Talos Energy is an independent oil 
and gas company led by a management 
team with decades of experience in 
offshore exploration and production. 
We are experts at acquiring operated 
shelf and developed deepwater assets 
in the Gulf of Mexico, then exploring, 
exploiting and optimizing those assets 
using innovative techniques and 
cutting-edge seismic technologies.

2018 was a historic year for Talos Energy 
as we completed and fully integrated our 
transformative merger with Stone Energy. 
The merger signifi cantly expanded the scale 
and operational breadth of Talos, and its 
benefi ts were immediately noticeable. 

Addi(cid:415) onally, the merger set the stage for us to more broadly share 

our story and values as a publicly-traded company focused on posi(cid:415) ve 
free cash fl ow, moderate, sustainable growth and balance sheet discipline. 
In 2018, Talos delivered solid fi nancial performance and successfully 
executed on a number of complex projects and we expect more of the 
same in 2019 and beyond.

We also believe in our diff eren(cid:415) ated strategy, which we have refi ned 
and validated over nearly two decades. We leverage our deep 
understanding of the basins in which we operate, the US Gulf of Mexico 
(“GOM”) and off shore Mexico, to iden(cid:415) fy and execute on highly economic 
drilling projects. In the US GOM, we are able to capitalize on the ample 
infrastructure and premium commodity pricing closely (cid:415) ed to Brent, 
and the current market environment further allows us to engage in low 
cost acquisi(cid:415) ons and infrastructure-led explora(cid:415) on and exploita(cid:415) on 
with conven(cid:415) onal off shore wells. These conven(cid:415) onal wells boast lower 
ini(cid:415) al declines as compared to onshore shale projects. Complimen(cid:415) ng 
these more mature assets, off shore Mexico provides Talos early access 
to an emerging basin with a signifi cant resource base in shallow water 
depths that allows for low oil price break-evens and facilitates shorter 
development cycles. I believe our por(cid:414) olio of assets will allow Talos to 
con(cid:415) nue to grow at a measured pace in the US GOM while con(cid:415) nuing 
to generate posi(cid:415) ve free cash fl ow, with the ini(cid:415) a(cid:415) on of produc(cid:415) on 
from our off shore Mexico assets driving a step-change in Talos’s 
produc(cid:415) on and cash fl ows in the future. 

As we conduct our opera(cid:415) ons, we con(cid:415) nue to live by the highest 
standards of health, safety and environmental focus and stewardship. 
We believe in and support the communi(cid:415) es along the coasts of both 
countries in which we operate, and we appreciate and deeply value 
the symbio(cid:415) c rela(cid:415) onship that we have with these communi(cid:415) es.

Quality Asset Base
Talos has a solid asset base from which to grow our company. We are 
currently execu(cid:415) ng on projects that will further stabilize our produc(cid:415) on 

base and add signifi cant new volumes in 2019. In addi(cid:415) on, I’m very 
excited about numerous drilling prospects that we have iden(cid:415) fi ed 
and are currently evalua(cid:415) ng. Some of these prospects are on previously 
held Talos leases while others have been added through our targeted 
business development eff orts.

Upon closing of the merger with Stone, we focused on lower-risk 
but high impact projects that could grow produc(cid:415) on in 2018 while 
also posi(cid:415) oning the company for sustainable growth and maintaining 
our ability to generate posi(cid:415) ve free cash fl ow for years to come. And 
our team has delivered on these goals to date. Our 2018 produc(cid:415) on was 
approximately 5% higher than pro forma 2017 Talos and Stone produc(cid:415) on 
and we increased Proved Developed reserves by 20%, as compared to 
our pro forma reserves as of December 31, 2017.

In November 2018, we ini(cid:415) ated the appraisal of the Zama discovery in 
off shore Mexico. I am extremely proud of our team for the opera(cid:415) onal 
excellence they have achieved in Mexico as we con(cid:415) nue to safely execute 
the project ahead of schedule and under budget.

Our Proved Reserves as of December 31, 2018 were 151.7 MMBoe, and the 
present value of these reserves discounted at 10% was $3.9 billion on a 
pre-tax basis. Approximately 80% of these reserves reside in our US GOM 
deepwater assets. Importantly, the Zama discovery in off shore Mexico 
is not yet included in our proved reserves, per SEC guidelines, un(cid:415) l we 
reach a Final Investment Decision (“FID”).

Low Entry Cost M&A and Best Prac(cid:415) ces Seismic Reprocessing 
Leads to Be(cid:425)  er Drilling Economics
A key aspect of our strategy is the variety of low cost business development 
opportuni(cid:415) es that are available to us. Talos is well-posi(cid:415) oned as a credible 
consolida(cid:415) on candidate in the US GOM and is ready to capitalize on the 
lower valua(cid:415) on market dynamics driven by the over-alloca(cid:415) on of capital 
in various onshore shale plays and the resul(cid:415) ng underinvestment in off shore 
projects. We were able to exploit some consolida(cid:415) on opportuni(cid:415) es in

2018 by closing three small bolt-on transac(cid:415) ons, including the Ram Powell 
and Gunfl int assets in our Mississippi Canyon core area and the Green 
Canyon 18 asset in our Green Canyon core area. These assets were acquired 
at compelling valua(cid:415) on metrics and add to our scalable infrastructure 
base upon which we will drive further growth.

In 2018, we commenced our appraisal program on the Zama discovery, 
which includes three reservoir penetra(cid:415) ons that we expect will advance 
our progress toward FID in 2020. Our fi rst penetra(cid:415) on was successful 
and in line with our expecta(cid:415) ons, thus valida(cid:415) ng our geophysical models. 
The appraisal program is expected to conclude by mid-year 2019.

Through these acquisi(cid:415) ons we have access to underu(cid:415) lized produc(cid:415) on 
facili(cid:415) es. The combina(cid:415) on of infrastructure with throughput capacity in 
an area where we have a deep geological exper(cid:415) se and our reprocessed 
seismic allows Talos to develop drilling opportuni(cid:415) es with enhanced 
economics. For example, since the announcement of our Green Canyon 18 
acquisi(cid:415) on, we were able to acquire nearby leases with subsea prospects 
through the semi-annual federal lease sale, we farmed into a lease as 
the operator with a drill-ready prospect, and we purchased a stranded 
discovery from Exxon, all of which will (cid:415) e into the Green Canyon 18 facility 
if they are successful. These business development ac(cid:415) vi(cid:415) es around 
acquired infrastructure exemplify our strategy of execu(cid:415) ng low-entry 
cost acquisi(cid:415) ons in order to facilitate a(cid:425) rac(cid:415) ve economic explora(cid:415) on, 
exploita(cid:415) on and development ac(cid:415) vi(cid:415) es.

Globally Recognized Zama Discovery
We opportunis(cid:415) cally entered off shore Mexico in the fi rst private sector 
lease auc(cid:415) on in July 2015 and competed against a number of globally 
recognized companies. We narrowly outbid the compe(cid:415) tors and were 
awarded two Produc(cid:415) on Sharing Contracts covering a total of over 
160,000 acres in Block 7 and Block 2, both in the Sureste Basin.

Our focus was on the explora(cid:415) on of the same geological trends that 
we focus on in the US GOM, which are the Lower Pliocene through the 
Miocene sec(cid:415) on. These geological trends have been under-explored in an 
otherwise prolifi c basin off shore Mexico. A(cid:332) er proprietarily reprocessing 
the available seismic data, in 2017 we drilled the fi rst off shore explora(cid:415) on 
well by the private sector in the history of Mexico resul(cid:415) ng in the Zama 
discovery, which was awarded the worldwide Discovery of the Year by 
Wood Mackenzie. This is an extremely pres(cid:415) gious honor for Talos and 
validates our ability to execute once-in-a-genera(cid:415) on projects. Projects 
like Zama serve to propel Talos forward as a compe(cid:415) (cid:415) ve force and an 
industry leader.

Building for the Future
I believe Talos maintains all of the cri(cid:415) cal elements necessary to con(cid:415) nue 
to drive material, long-term value crea(cid:415) on for our shareholders. The 
company’s strategy has been validated through mul(cid:415) ple commodity 
cycles by focusing on an environment we know best, being both pa(cid:415) ent 
and opportunis(cid:415) c, and conserva(cid:415) vely managing cash fl ow and leverage 
to protect our balance sheet and capital program. Today, I am very 
proud that Talos has been able to generate posi(cid:415) ve free cash fl ow while 
so many companies in our industry have not been able to do so. We 
have also accumulated a deep inventory of highly economic projects 
and a globally recognized discovery in Zama, maintained a conserva(cid:415) ve 
balance sheet and established ourselves as a trusted counterparty to 
transact with. We believe that we have established a great founda(cid:415) on 
to build on.

In 2018, we asked a lot of our team. We successfully integrated a 
signifi cant merger while simultaneously taking our fi rst steps as a 
publicly-traded company. We balanced a series of challenging projects 
and acquisi(cid:415) ons that helped expand the scale of our business. And we 
advanced our world-class Zama discovery towards future FID on schedule. 
Throughout all of these ac(cid:415) vi(cid:415) es, we proved we can reliably generate 
posi(cid:415) ve free cash fl ow, maintain appropriate debt and liquidity metrics and 
deliver opera(cid:415) onally. I am pleased with all that Talos has accomplished 
in 2018, but we’re already looking ahead. I am truly excited about what 
the future holds.

Sincerely Yours,

Talos is a growing company 
that fosters an entrepreneurial 
culture of development. 

We pair the profi ciency of our geological and engineering staff  with cu(cid:427)  ng-edge science 
and technology. By combining the infl uence of refi ned data and the transfer of knowledge 
and best prac(cid:415) ces, we enrich our ability to access hydrocarbon reservoirs more safely, 
resourcefully and in a manner that protects both the public and the environment. 

The safety, health and welfare of employees, contractors, visitors and the public is our 
number one priority and foremost core value. Talos off ers compe(cid:415) (cid:415) ve benefi ts, fl exible work 
schedules to promote work/life balance, opportuni(cid:415) es for advancement and much more. 

Every year since our incep(cid:415) on, Talos has been ranked a Top Workplace on the Houston Chronicle 
Top Workplaces list. We strive to make a posi(cid:415) ve impact on our local community through 
our Community Commi(cid:425) ee. Our community ma(cid:425) ers greatly to us, and has given our employees 
so much that we feel it’s our responsibility to give back. We off er a $500 annual allowance 
for each employee that can be used towards a not-for-profi t organiza(cid:415) on of their choice. 
Whether it be a community fundraiser, a child’s athle(cid:415) c team, or a cause-worthy dona(cid:415) on, 
our employees know Talos stands behind them. 

In addi(cid:415) on, we also hold quarterly events with na(cid:415) onal and local organiza(cid:415) ons such as 
Houston Children’s Charity, Houston Food Bank and Oilfi eld Helping Hands in order to 
provide direct opportuni(cid:415) es for our employees to make a diff erence.

HSE AT TALOS ENERGY:

KEY 2018 TALOS HSE ACCOMPLISHMENTS INCLUDE:

2018 was an exci(cid:415) ng year for Talos. We acquired 
new key assets, added talent and solidifi ed our

Phoenix Complex

The Phoenix Complex, located in our Green Canyon core area, is the biggest 

producing asset in our por(cid:414) olio. The complex includes the Tornado fi eld, which 

Talos discovered in 2016. Following the discovery, Talos drilled a second well in 

the fi eld and began produc(cid:415) on from it in December 2017. In December of 2018, 

Talos successfully drilled the third well in the Tornado fi eld and expects to 

commence produc(cid:415) on during the second quarter of 2019.

Produc(cid:415) on from the Phoenix Complex fl ows to the Helix Producer-1 ship, 

which successfully completed its regulatory dry-dock in the fi rst quarter of 2019. 

In addi(cid:415) on to Tornado 3, we also drilled the Boris 3 well in January of 2019, which 

we also expect to commence produc(cid:415) on during the second quarter of 2019.

Average produc(cid:415) on from the Phoenix Complex in 2018 was approximately 

17,900 Boe per day and as of December 31, 2018, the proved reserves were 

63.9 MMBoe, of which 78% was oil and 86% was liquids.

Pompano and Amberjack

Pompano and Amberjack were acquired as part of the merger with Stone Energy, and they provide 

a solid founda(cid:415) on for growth in the area. In July of 2018, Talos commenced produc(cid:415) on from the 

Mt. Providence well, which was a subsea (cid:415) eback to the Pompano produc(cid:415) on facility. 

From the closing of the Stone Energy merger to December 31, 2018, average produc(cid:415) on from the 

Mississippi Canyon core area was approximately 12,555 Boe per day, and as of December 31, 2018, 

the proved reserves were 36.4 MMBoe, of which 83% was oil and 87% was liquids.

Ram Powell

Ram Powell was acquired from subsidiaries of Royal Dutch Shell, ExxonMobil 

Corpora(cid:415) on and Anadarko Petroleum Corpora(cid:415) on in May of 2018, immediately 

prior to the closing of the merger with Stone Energy. The asset is located in a 

strategic area of the US Gulf of Mexico where oil discoveries have been made 

in recent years. Talos expects to commence an explora(cid:415) on and exploita(cid:415) on 

drilling campaign around Ram Powell in the coming years.

Average produc(cid:415) on from Ram Powell in 2018, from the closing of the Stone 

Energy merger to December 31, 2018, was approximately 7,856 Boe per day. 

As of December 31, 2018, proved reserves were 18.1 MMBoe, of which 59% 

was oil and 72% was liquids.

Talos was awarded the Block 2 Produc(cid:415) on Sharing Contract in 2015. In 2018, Talos 

signed a cross-assignment of interest with a subsidiary of Pan American Energy to 

acquire 25% in Block 31, in exchange for 25% in Block 2 to Pan American, subject 

to government approvals.

In 2018, Talos concluded its technical study of Blocks 2 and 31. In 2019, we expect 

to drill four wells in the area. Of those, the Olmeca project has been de-risked by 

a Pemex well drilled in 2003. The 2019 drilling campaign will appraise the same

proceeds from the sale of such production exceed production expenses and taxes.

Proved developed reserves. In general, proved reserves that can be expected to be recovered from existing wells 
with  existing  equipment  and  operating  methods.  The  Securities  and  Exchange  Commission  provides  a  complete 
definition of developed oil and gas reserves in Rule 4-10(a)(6) of Regulation S-X.

3

6696_10K.pdf

Proved reserves. Proved reserves are those quantities of oil and natural gas, which, by analysis of geoscience and 
engineering  data,  can  be  estimated  with  reasonable  certainty  to  be  economically  producible  –  from  a  given  date 
forward,  from  known  reservoirs  and  under  existing  economic  conditions,  operating  methods  and  government 
regulations — prior to the time at which contracts providing the right to operate expire, unless evidence indicates 
that  renewal  is  reasonably  certain,  regardless  of  whether  deterministic  or  probabilistic  methods  are  used  for  the 
estimation.  The  project  to  extract  the  hydrocarbons  must  have  commenced  or  the  operator  must  be  reasonably 
certain that it will commence the project within a reasonable time.

Proved  undeveloped  reserves.  In  general,  proved  reserves  that  are  expected  to  be  recovered  from  new  wells  on 
undrilled  acreage  or  from  existing  wells  where  a  relatively  major  expenditure  is  required  for  recompletion.  The 
Securities  and  Exchange  Commission  provides  a  complete  definition  of  undeveloped  oil  and  gas  reserves  in 
Rule 4-10(a)(31) of Regulation S-X.

PV-10.  The  present  value  of  estimated  future  revenues,  discounted  at  10%  annually,  to  be  generated  from  the 
production of proved reserves determined in accordance with Securities and Exchange Commission guidelines, net 
of estimated production and future development costs, using prices and costs as of the date of estimation without 
future  escalation,  without  giving  effect  to  (i)  non-property  related  expenses  such  as  general  and  administrative 
expenses, derivatives, debt service and future income tax expense or (ii) depreciation depletion and amortization 
expense.

SEC. The Securities and Exchange Commission.

SEC pricing. The unweighted average first-day-of-the-month commodity price for crude oil or natural gas for the 
period beginning January 1, 2018 and ending December 1, 2018, adjusted by lease for market differentials (quality, 
transportation,  fees,  energy  content,  and  regional  price  differentials).  The  Securities  and  Exchange  Commission 
provides a complete definition of prices in “Modernization of Oil and Gas Reporting” (Final Rule, Release Nos. 
33-8995; 34-59192).

Shelf. Water depths up to 600 feet.

Standardized Measure: The present value of estimated future net revenue to be generated from the production of 
proved reserves, determined in accordance with the rules, regulations or standards established by the SEC and the 
Financial Accounting Standards Board (“FASB”) (using prices and costs in effect as of the date of estimation), less 
future development, production and income tax expenses, and discounted at 10% per annum to reflect the timing of 
future net revenue. For the year ending December 31, 2018, we were subject to U.S. federal and state income taxes 
at the entity level. For the tax years ending December 31, 2017 and 2016, we were not subject to U.S. federal or 
state income taxes (in most states) at the entity level and thus made no provision for U.S. federal or state income 
taxes  in  the  calculation  of  our  standardized  measure.  Standardized  measure  does  not  give  effect  to  derivative 
transactions.

Undeveloped  acreage.  Lease  acreage  on  which  wells  have  not  been  drilled  or  completed  to  a  point  that  would 
permit the production of commercial quantities of oil and gas regardless of whether such acreage contains proved 
reserves.

Working  interest.  The  operating  interest  that  gives  the  owner  the  right  to  drill,  produce  and  conduct  operating 
activities on the property and a share of production.

WTI  or  West  Texas  Intermediate.  A  light  crude  oil  produced  in  the  United  States  with  an  API  gravity  of 
approximately 38-40 and the sulfur content is approximately 0.3%.

We caution you that these forward-looking statements are subject to numerous risks and uncertainties, most 
of which are difficult to predict and many of which are beyond our control. These risks include, but are not limited 
to,  commodity  price  volatility,  inflation,  lack  of  availability  of  drilling  and  production  equipment  and  services, 
environmental  risks,  failure    to  find,  acquire  or  gain  access  to  other  discoveries  and  prospects  or  to  successfully 
develop and produce from our current discoveries and prospects, geologic risk, drilling and other operating risks, 
well control risk, regulatory changes, the uncertainty inherent in estimating reserves and in projecting future rates 
of production, cash flow and access to capital, the timing of development expenditures, potential adverse reactions 
or competitive responses to the business combination between Talos Energy LLC and Stone Energy Corporation, 
the possibility that the anticipated benefits of such business combination are not realized when expected or at all, 
including as a result of the impact of, or problems arising from, the integration of the two companies, and the other 
risks discussed in Part I, Item 1A, “Risk Factors” which are included herein.

Reserve engineering is a process of estimating underground accumulations of oil, natural gas and NGLs that 
cannot be measured in an exact way. The accuracy of any reserve estimate depends on the quality of available data, 
the interpretation of such data and price and cost assumptions made by reserve engineers. In addition, the results of 
drilling, testing and production activities may justify upward or downward revisions of estimates that were made 
previously.  If  significant,  such  revisions  would  change  the  schedule  of  any  further  production  and  development 
drilling. Accordingly, reserve estimates may differ significantly from the quantities of oil, natural gas and NGLs 
that are ultimately recovered. 

Should  one  or  more  of  the  risks  or  uncertainties  described  herein  occur,  or  should  underlying  assumptions 
prove incorrect, our actual results and plans could differ materially from those expressed in any forward-looking 
statements. All forward-looking statements, expressed or implied, included in this report are expressly qualified in 
their entirety by this cautionary statement. This cautionary statement should also be considered in connection with 
any  subsequent  written  or  oral  forward-looking  statements  that  we  or  persons  acting  on  our  behalf  may  issue. 
Except as otherwise required by applicable law, we disclaim any duty to update any forward-looking statements, all 
of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of 
this report.

Items 1. Business 

Overview

PART 1

We are a technically driven independent exploration and production company with operations in the United 
States Gulf of Mexico and offshore Mexico. Our focus in the United States Gulf of Mexico is the acquisition of 
deep water assets with existing infrastructure and the exploration, exploitation and development of such assets in 
key geological trends. Offshore Mexico provides us high impact exploration opportunities in an oil rich emerging 
basin. We use our access to an extensive seismic database and our deep technical expertise to identify, acquire and 
exploit attractive assets with robust economic profiles. As of December 31, 2018, deepwater assets represent 83% 
of our proved reserves. 

We have historically focused our operations in the Gulf of Mexico because we believe this area provides us 
with favorable geologic and economic conditions, including multiple reservoir formations, comprehensive geologic 
databases, extensive infrastructure and an attractive acquisition market and because we have significant experience 
and technical expertise in the basin. Additionally, we have access to state-of-the-art three-dimensional seismic data, 
some of which is aided by new and enhanced reprocessing techniques that have not been previously applied to our 
current  acreage  position.  We  use  our  broad  regional  seismic  database  and  our  reprocessing  efforts  to  generate  a 
large and expanding inventory of high-quality prospects, which we believe greatly improves our development and 
exploration  success.  The  application  of  our  extensive  seismic  database,  coupled  with  our  ability  to  effectively 
reprocess this seismic data, allows us to both optimize our organic drilling program and better evaluate acquisition 
and joint venture opportunities.

In order to determine the most attractive returns for our drilling program, we employ a disciplined portfolio 
management  approach  to  stochastically  evaluate  all  of  our  drilling  prospects,  whether  they  are  generated 
organically from our existing acreage or are acquisition or joint venture opportunities. We add to and reevaluate 
our inventory in order to deploy capital as efficiently as possible.

Talos Energy Inc. was incorporated on November 14, 2017 under the laws of the state of Delaware for the 
purpose of effecting the previously disclosed business combination between Talos Energy LLC (“Talos Energy”) 
and Stone Energy Corporation (“Stone”), pursuant to which each of Talos Energy and Stone became our wholly-
owned  subsidiary.  We  refer  to  this  business  combination  as  the  “Stone  Combination,”  and  its  date  of 
consummation,  May  10,  2018,  as  the  “Closing  Date.”  In  addition,  as  used  in  this  report  and  unless  otherwise 
indicated or the context otherwise requires, references to “we,” “us,” “our,” “Talos Energy Inc.,” “Talos” and the 
“Company” refer to, from and after the Closing Date, Talos Energy Inc. and its consolidated subsidiaries and prior 
to the Closing Date, Talos Energy and its consolidated subsidiaries. 

Prior to the Stone Combination, Talos Energy Inc. had not conducted any material activities other than those 
incident  to  its  incorporation  and  certain  matters  contemplated  by  that  certain  Transaction  Agreement  (the 
“Transaction Agreement”), dated as of November 21, 2017, among Stone, Talos Energy, us and Sailfish Merger 
Sub Corporation (“Merger Sub”). The transactions contemplated by the Transaction Agreement were accounted for 
as  a  business  combination  in  accordance  with  accounting  principles  generally  accepted  in  the  United  States  of 
America (“GAAP”), with Talos Energy treated as the “acquirer” and Stone treated as the “acquired” company for 
financial  reporting  purposes.  Accordingly,  the  reported  financial  condition  and  results  of  operations  of  Talos 
Energy Inc. reflect the assets, liabilities and results of operations of Talos Energy (as our predecessor) prior to the 
Closing  Date,  and  do  not  reflect  the  assets,  liabilities  and  results  of  operations  of  Stone  prior  to  such  date.  The 
assets,  liabilities  and  results  of  operations  of  Talos  Energy  Inc.  have  not  been,  and  will  not  be,  restated 
retrospectively to reflect the historical financial position or results of operations of Stone.

For  more  information  on  Talos  Energy,  our  predecessor  for  financial  reporting  purposes,  please  read  “—

Talos Energy LLC.” For more information on the Stone Combination, please read “— Stone Combination.”

Talos Energy LLC

Talos  Energy  was  formed  in  2011  under  the  laws  of  the  state  of  Delaware  and  commenced  commercial 
operations  on  February  6,  2013.  Prior  to  February  6,  2013,  Talos  Energy  had  incurred  only  certain  general  and 
administrative expenses associated with the start-up of its operations.  

7

6696_10K.pdf

On  February  3,  2012,  Talos  Energy  completed  a  transaction  with  funds  and  other  alternative  investment 
vehicles managed by Apollo Management VII, L.P. and Apollo Commodities Management, L.P., with respect to 
Series  I  (“Apollo  Funds”),  and  entities  controlled  by  or  affiliated  with  Riverstone  Energy  Partners  V,  L.P. 
(“Riverstone Funds”, and together with the Apollo Funds, the “Sponsors”) and members of management pursuant 
to which Talos Energy received a private equity capital commitment.

On February 6, 2013, Talos Energy acquired all of the equity of Energy Resource Technology GOM, LLC 
(“ERT”)  and  its  subsidiary  from  Helix  Energy  Solutions  Group,  Inc.  (“Helix”)  for  approximately  $625.2 million 
(inclusive  of  purchase  price  and  working  capital  adjustments  of  approximately  $15.2 million),  and  payments  for 
ongoing  guarantees  from  Helix  to  third-parties.  Additionally,  Talos  Energy  agreed  to  assign  Helix  an  overriding 
royalty interest in certain properties acquired in the transaction at closing. We refer to this purchase as the “ERT 
Acquisition.” The ERT Acquisition was effective December 1, 2012 and closed on February 6, 2013. Prior to the 
closing  of  the  ERT  Acquisition,  the  Sponsors  and  members  of  management  had  invested  an  aggregate  of 
approximately $325 million in Talos Energy to fund a portion of the ERT Acquisition as well as to fund other asset 
purchases. 

In September 2015, Talos Energy, together with consortium partners Sierra Oil and Gas S. de R.L de C.V. 
(“Sierra”) and Premier Oil Plc (“Premier”, and together with Talos Energy and Sierra, the “Consortium”) executed 
two Production Sharing Contracts (“PSCs”) with the National Hydrocarbons Commission (“CNH”), Mexico’s oil 
and gas regulator, for Blocks 2 and 7 of Round 1. The PSCs were awarded to the Consortium during the first tender 
of Mexico’s oil and natural gas fields in over 80 years. Blocks 2 and 7 are located in the Sureste Basin, a prolific 
proven  hydrocarbon  province,  in  the  shallow  waters  off  the  coast  of  Mexico’s  Veracruz  and  Tabasco  states, 
respectively. Blocks 2 and 7 contain approximately 162,904 gross acres with numerous high impact prospects in 
well-established and emerging plays. In 2017, the Consortium drilled Zama-1, the initial exploration well in Block 
7, resulting in the discovery of the Zama Field.  As of December 31, 2018, we were in the process of appraising the 
discovery.

Stone Combination

On  the  Closing  Date,  we  consummated  the  transactions  contemplated  by  the  Transaction  Agreement  and 
Talos  Energy  and  Stone  became  our  wholly-owned  subsidiaries.  Pursuant  to  the  Transaction  Agreement,  the 
following  transactions,  among  others,  occurred:  (i) Stone  underwent  a  reorganization  pursuant  to  which  Merger 
Sub merged with and into Stone, with Stone continuing as the surviving corporation and our direct wholly-owned 
subsidiary (the “Merger”), and each share of Stone’s common stock outstanding immediately prior to the Merger 
(other than treasury shares held by Stone, which were cancelled for no consideration) was converted into the right 
to receive one share of our common stock, par value $0.01 (the “Common Stock”) and (ii) the Sponsors contributed 
all of the equity interests in Talos Production LLC (“Talos Production”) (which at that time owned 100% of the 
equity interests in Talos Energy) to us in exchange for an aggregate of 31,244,085 shares of Common Stock (the 
“Sponsor Equity Exchange”).

Concurrently  with  the  consummation  of  the  Transaction  Agreement,  we  consummated  the  transactions 
contemplated by that certain Exchange Agreement, dated as of November 21, 2017 (the “Exchange Agreement”), 
among us, Stone, the Talos Issuers (defined below), the various lenders and noteholders of the Talos Issuers listed 
therein, certain funds controlled by Franklin Advisers, Inc. (“Franklin”) (such controlled noteholders, the “Franklin 
Noteholders”), and certain clients of MacKay Shields LLC (“MacKay Shields”) (such noteholders, the “MacKay 
Noteholders”),  pursuant  to  which  (i) the  Apollo  Funds  and  Riverstone  Funds  contributed  $102.0 million  in 
aggregate  principal  amount  of  9.75%  senior  notes  due  2022  (“9.75%  Senior  Notes”)  issued  by  Talos  Production  
and Talos Production Finance, Inc. (together, the “Talos Issuers”) to us in exchange for an aggregate of 2,874,049 
shares  of  Common  Stock  (the  “Sponsor  Debt  Exchange”);  (ii)  the  holders  of  second  lien  bridge  loans  (“11.00% 
Bridge  Loans”)  issued  by  the  Talos  Issuers  exchanged  such  11.00%  Bridge  Loans  for  $172.0  million  aggregate 
principal amount of 11.00% Second-Priority Senior Secured Notes due 2022 of the Talos Issuers (“11.00% Senior 
Secured  Notes”)  and  (iii) Franklin  Noteholders  and  MacKay  Noteholders  exchanged  their  7.50%  Senior  Secured 
Notes due 2022 issued by Stone (“7.50% Stone Senior Notes”) for $137.4 million aggregate principal amount of 
11.00% Senior Secured Notes.

8

6696_10K.pdf

Substantially concurrent therewith, we consummated an exchange offer and consent solicitation, pursuant to 
which the holders of the 7.50% Stone Senior Notes, excluding the 7.50% Stone Senior Notes held by the Franklin 
Noteholders and the MacKay Noteholders, exchanged their 7.50% Stone Senior Notes for 11.00% Senior Secured 
Notes and a cash payment, and a solicitation of consents to proposed amendments to the 7.50% Stone Senior Notes. 
Approximately  $81.5  million  in  aggregate  principal  amount  of  the  7.50%  Stone  Senior  Notes  were  validly 
tendered,  and  approximately  $6.1  million  in  aggregate  principal  amount  of  7.50%  Stone  Senior  Notes  remained 
outstanding as of the Closing Date.

As a result of the closing of the transactions contemplated by the Transaction Agreement and the Exchange 
Agreement  (the  “Transactions”)  the  former  stakeholders  of  Talos  Energy  held  approximately  63%  of  the 
Company’s  outstanding  Common  Stock  and  the  former  stockholders  of  Stone  held  approximately  37%  of  the 
Company’s outstanding Common Stock as of the Closing Date.

Business Strategy

We intend to increase stockholder value through the following strategies:

Grow  Production,  Reserves  and  Cash  Flow  by  Developing  Our  Attractive  Asset  Base  in  a  Capital  Efficient 
Manner. 

Our  team  is  focused  on  continuously  improving  capital  efficiency,  and  we  believe  the  combination  of  our 
experience  and  the  existing  infrastructure  in  the  U.S.  Gulf  of  Mexico  will  allow  us  to  continue  to  benefit  from 
attractive  finding  and  development  costs.  We  also  benefit  from  our  proven  ability  to  increase  production  from 
legacy fields and identified projects. Furthermore, we intend to use our technical expertise and seismic database to 
find additional drilling projects in proximity to our existing assets.

Expand Our Reserves and Production Through Lease Acquisitions and Diversified Business Development. 

We intend to deploy our expertise and seismic resources to identify and acquire attractive leasehold acreage 
in federal lease sales for the U.S. Gulf of Mexico. In many cases, acreage available in the federal lease sales has not 
been  evaluated  with  the  latest  reprocessed  seismic  data,  resulting  in  an  opportunity  for  us  to  identify  previously 
unknown drilling prospects. In the latest federal lease of the August 2018 sale, we were the fifth most active bidder 
in the U.S. Gulf of Mexico, and we were the high bidder on 14 lease blocks. During that sale, we focused on blocks 
that adjoin our existing properties, and we have identified specific prospects through reprocessed seismic data. In 
addition, our proven track record through the drillbit and our strong financial position frequently attracts potential 
drilling partners. Our deep industry relationships, technical expertise and extensive regional seismic database allow 
us  to  effectively  identify  and  evaluate  these  third-party  proposed  drilling  projects.  We  intend  to  continue  to 
strategically pursue these types of drilling projects with other operators on a selected basis.

Evaluate and Pursue Accretive Acquisitions.

We  intend  to  continue  to  opportunistically  expand  our  asset  base  by  evaluating  the  supply  of  acquisition 
opportunities  in  the  U.S.  Gulf  of  Mexico  and  offshore  Mexico.  Our  acquisition  strategy  is  focused  on  operated 
deepwater  assets  with  a  geological  setting  that  can  benefit  from  our  ability  to  use  our  seismic  database  and  our 
reprocessing expertise to re-evaluate the acquired assets. By applying our disciplined valuation methodology, we 
seek  to  reduce  the  risk  of  underperformance  of  the  acquired  properties  while  maintaining  upside  potential.  In 
addition,  we  may  consider  acquisition  opportunities  in  other  offshore  basins  with  analogous  geologies  that  are 
suitable  for  our  operational  and  technical  expertise  to  the  extent  we  believe  they  will  create  additional  value  for 
stockholders.

Maintain High Operatorship to Leverage Our Technical Expertise. 

We  operate  properties  that  generate  approximately  94%  of  our  production,  and  we  strive  to  maintain  a 
majority  of  operational  control  over  our  producing  properties.  We  believe  that  maintaining  control  of  our 
production  enables  us  to  apply  leading  practices  to  every  aspect  of  our  operations.  In  addition,  maintaining  high 
operatorship allows us to leverage our technical team’s deep regional experience and modern seismic expertise in 
order  to  generate  attractive  investment  opportunities  on  our  properties  while  concurrently  controlling  execution.

Properties 

United States Gulf of Mexico Properties

Our  area  of  focus  in  the  United  States  is  the  Gulf  of  Mexico  deepwater,  which  is  generally  considered  to 
comprise  water  depths  over  600  feet.  Our  strategy  is  focused  in  areas  characterized  by  clearly  defined 
infrastructure,  well  known  production  history  and  geological  well  control,  which  reduces  operational  and 
investment risk. We believe the potential for large discoveries and increasing success rates in the sub-salt and mini-
basin lower Pliocene and Miocene plays have resulted in increased industry focus on this area over the last decade.  

We  believe  our  deepwater  operations  in  the  U.S.  Gulf  of  Mexico  provide  significant  potential  growth 
opportunities  through  our  planned  drilling  program.  Through  our  technical  approach  of  starting  with  known 
hydrocarbon  systems  and  applying  modern  seismic  reprocessing  techniques,  we  have  generated  a  substantial 
inventory  of  deepwater  prospects  that  we  believe  are  capable  of  delivering  predictable  production  growth.  We 
focus  our  exploitation  and  exploration  efforts  around  our  existing  infrastructure.  This  subsea  tie-back  strategy 
allows for better project economics and shorter periods between a discovery and production.

In  the  United  States,  at  December 31,  2018,  we  had  an  interest  in  271.0  gross  producing  wells  (228.9 
net producing  wells)  on  885,888  gross  (624,891  net)  total  acres,  of  which  477,190  gross  (342,604  net)  are 
developed acres. We operate properties that contain 98% of our proved reserves at December 31, 2018. 

At December 31, 2018, our core properties in the United States, which represent approximately 68% of our 

2018 production and 78% of our December 31, 2018 proved reserves are illustrated below:

Production volumes and estimated proved reserves include the Tornado, Boris and Typhoon areas of the Phoenix Field, all of which tie 
back to the HP-I.

Production  volumes  and  estimated  proved  reserves  include  the  Pompano  and  Cardona  Fields,  both  of  which  tie  back  to  the  Pompano 
Platform.

Other United States Properties includes Gulf of Mexico shelf and deepwater.

Production for the Pompano, Ram Powell and Amberjack Core Properties are presented from the Closing Date of the Stone Combination 
through December 31, 2018.

Phoenix Field—The Phoenix Field is comprised of six operated blocks, which include Green Canyon Blocks 

236, 237, 238, 280, 281, and 282, located in the deepwaters offshore Louisiana.

There are no conventional fixed or moored production platforms in the field-instead the subsea wells are tied 
back to a dynamically positioned floating production unit, the Helix Producer I (“HP-I”). The HP-I interconnects 
with the Phoenix Field through a production buoy that can be disconnected if the HP-I cannot maintain its position 
on  station,  such  as  the  approach  of  a  hurricane  or  in  the  event  of  a  mechanical  problem  with  the  dynamic 
positioning system. There are eight active wells in the Phoenix Field and the average net daily production for the 
year ended December 31, 2018 was 17,907 Boepd.

Pompano  Field—  The  Pompano  Field  is  comprised  of  seven  operated  blocks  which  include  Viosca  Knoll 
Blocks  989  and  990,  and  Mississippi  Canyon  Blocks  26,  27,  28,  29  and  72  located  in  the  deepwaters  offshore 
Louisiana. The Pompano Field’s three current subsea systems are tied back to a fixed leg platform with a total of 23 
active wells. The field’s average net daily production since the Closing Date of the Stone Combination was 10,534 
Boepd. 

Ram Powell Field— The Ram Powell Field is comprised of six operated blocks which include Viosca Knoll 
Blocks 911, 912, 913, 955, 956 and 957 located in the deepwaters offshore Louisiana. The Ram Powell Field has 
eight active dry tree wells that are located on a tension leg platform in Viosca Knoll Block 956. The field’s average 
net daily production since the Closing Date of the Stone Combination was 7,856 Boepd. 

Amberjack  Field—The  Amberjack  Field  is  comprised  of  three  operated  blocks  which  include  Mississippi 
Canyon Block 108, 109 and 110. The Amberjack Field has 29 active conventional dry tree wells located on a fixed 
structure  platform  in  Mississippi  Canyon  Block  109.  The  field’s  average  net  daily  production  since  the  Closing 
Date of the Stone Combination was 2,021 Boepd.

Mexico Properties

In September 2015, we, together with the Consortium, executed a PSC with the CNH for each of Blocks 2 
and 7 of Round 1. The PSCs were awarded to the Consortium during the first tender of Mexico’s oil and natural 
gas fields in over 80 years. Blocks 2 and 7 are located in the Sureste Basin, a prolific proven hydrocarbon province, 
in the shallow waters off the coast of Mexico’s Veracruz and Tabasco states, respectively. Blocks 2 and 7 contain 
approximately 162,904 gross acres with numerous high impact prospects in well-established and emerging plays. 
Our participation interest (“PI”) in Block 2 is currently 20% and our PI in Block 7 is 35%. We are the operator of 
Block 7.

The PSCs include a cost recovery feature pursuant to which eligible costs in relation to the minimum work 
program activities are recoverable in-kind at a rate of 125% of costs from future production volumes. Production 
volumes are allocated in-kind between the Consortium and the United Mexican States on a monthly basis based on 
the contractual value of the hydrocarbons as defined in the PSCs. Up to 60% of the monthly contractual value of 
the  hydrocarbons  will  be  allocated  to  the  Consortium  to  recover  eligible  costs  incurred  in  petroleum  activities. 
Eligible  costs  exceeding  60%  of  the  current  month  contractual  value  of  the  hydrocarbons  will  be  recoverable  in 
future periods. Between 7.5% and 14% of the contractual value of the oil will be allocated to the United Mexican 
States  in  the  form  of  a  royalty,  depending  upon  the  price  of  a  barrel  of  oil,  with  a  collar  between  $48.00  and 
$100.00 per Bbl. The allocation for the royalty on natural gas is 0% when the price per MMBtu is below $5.00 and, 
if the natural gas price exceeds $5.00 per MMBtu, the royalty allocation percentage is calculated as the price per 
MMBtu  divided  by  100.  The  remaining  value  of  the  hydrocarbons  after  the  allocation  for  cost  recovery  and 
royalties is considered operating profit under the PSCs. The allocation of operating profit to the Consortium after 
the allocation for cost recovery and royalties on Blocks 2 and 7 is 44% and 31%, respectively. Additionally, in the 
event that the cumulative project internal rate of return in any one month exceeds 25%, the barrels of oil allocated 
to the Consortium after cost recovery (“Profit Oil”) is reduced on a sliding scale. The reduction in Profit Oil varies 
linearly  between  0%  and  75%  of  the  entitled  amount.  The  maximum  75%  reduction  occurs  once  the  cumulative 
project internal rate of return meets or exceeds 40%. 

At December 31, 2018, our core properties in Mexico are presented in the following acreage map: 

• Block 7— In July 2017, we completed drilling operations on the offshore Mexico Zama-1 exploration well 
in Block 7, reaching a total depth of 13,480 feet. The Zama-1 well is the first offshore exploration well to 
be drilled in Mexico by the private sector. Well results confirmed the base of the reservoir section, with no 
penetration  of  an  oil-water  contact.  The  gross  oil  bearing  interval  is  over  1,100  feet  with  petrophysical 
data indicating excellent rock properties and an oil sample with 30 degree American Petroleum Institute 
(“API”) gravity oil. The well has been suspended as a future producer. We are now analyzing all the data 
gathered from the Zama-1 well and evaluating the optimal methods for appraisal and development of the 
discovery. These contingent resources are not included in proved reserves. 

12

6696_10K.pdf

In the fourth quarter of 2018, we spud the Zama-2 well, the first appraisal well to be drilled in the field. 
The  Zama-2  well  confirmed  the  results  of  the  original  Zama-1  exploration  well.  The  Zama  appraisal 
campaign is expected to be completed by mid-year 2019. If the appraisal of the Zama Field confirms our 
initial  estimates,  we  expect  to  announce  a  Final  Investment  Decision  in  2020,  following  Mexican 
government  approval  of  the  development  plan.  In  addition  to  Zama,  other  prospects  within  Block  7  are 
being analyzed and matured to potentially be drilled over the next several years, assuming an extension of 
the  Exploration  Period  is  approved  by  the  CHH.  See  Part  II,  Item  8.  Financial  Statements  and 
Supplementary Data — Note 4 — Property, Plant & Equipment for further detail on Mexico properties.

Pre-Unitization  Agreement  with  Pemex.  In  September  2018,  we  and  our  consortium  partners  in  Block  7 
signed a Pre-Unitization Agreement (“PUA”) with Pemex Exploration y Produccion (“Pemex”) related to 
certain  tracts  within  the  Amoca-Yaxche-03  allocation  and  the  contiguous  Block  7  PSC.  Both  areas  are 
situated  in  the  offshore  portion  of  the  Sureste  Basin.  The  two  year  PUA  enables  information  sharing 
related to the Zama discovery and potential extension into Pemex’s neighboring block. The PUA has been 
approved by the Mexican Secretariat of Energy (“SENER”). 

• Block 2—In September 2018, we entered into a transaction (the “Hokchi Cross Assignment”) with Hokchi 
Energy,  S.A.  de  C.V.  (“Hokchi”),  a  subsidiary  of  Pan  American  Energy  LLC  (“PAE”),    to  cross  assign 
25% PIs in Block 2 and Block 31. Our assignment of a 25% PI in Block 2 to Hokchi closed on December 
21, 2018, and Hokchi has assumed operator responsibilities with respect to Block 2. Hokchi’s assignment 
of an interest in Block 31 to us will be completed upon final approval by the CNH. In addition, Premier 
exercised its option to reduce its PI in Block 2 to zero and assign a 5% PI to each of Sierra and us. Such 
assignment  is  also  subject  to  CNH’s  approval.  Upon  completion  of  the  Hokchi  Cross  Assignment  and 
Premier’s option exercise, we will own a 25% PI in each of Block 2 and Block 31, and Hokchi will be the 
operator of both blocks.

In  February  2019,  the  CHN  granted  approval  for  drilling  in  the  Acan-1  exploration  well  in  Block  2. 
Operations are expected to begin in March 2019 and extend into the second quarter. Soon thereafter, we 
plan to participate in two prospects in Block 31. Beyond the Acan prospects, we believe that Blocks 2 and 
31  contain  a  significant  portfolio  of  compelling  prospects  with  strong  technical  ties  to  offsetting 
discoveries.

Recent Developments

Gunflint Acquisition

On  January  11,  2019,  pursuant  to  a  Purchase  Sale  Agreement  with  Samson  Offshore  Mapleleaf,  LLC  we 
acquired  an  approximate  9.6%  non-operated  working  interest  in  the  Gunflint  Field  located  in  the  Mississippi 
Canyon area for $29.6 million.

HP-I Dry-Dock Downtime

During  the  first  quarter  of  2019,  the  HP-I  entered  into  its  regulatory  required  dry-dock  period.  Regulators 
require  the  ship  to  go  to  dry-dock  twice  every  five  years.  On  May  7,  2019,  the  HP-I  completed  its  dry-dock 
requirement and departed the shipyard. After a period of sea trials, we expect production from the Phoenix Field to 
commence in late March 2019. The annualized production impact of the shut-in in the Phoenix Field is estimated to 
be between 2.0 MBoepd and 3.0 MBoepd.

Drilling and Exploration Activities

The Tornado 3 well’s drilling operations completed in December 2018 and completed in January 2019. We 
expect production to commence by early second quarter, 2019, with an expected net production rate between 10.0 
MBoepd and 15.0 MBoepd. We are the operator and own a 65% working interest.

The  Boris  3  wells  started  drilling  operations  in  January  2019  and  completed  in  February  2019.  We  expect 
production  to  commence  in  the  second  quarter  of  2019,  with  a  net  production  between  or  2.8  Mboepd  and  4.6 
MBoepd. We are the operator and own a 100% working interest.

Reconciliation of PV-10 to Standardized Measure

PV-10 is a non-GAAP financial measure and differs from the standardized measure of discounted future net 
cash  flows,  which  is  the  most  directly  comparable  GAAP  financial  measure.  PV-10  is  a  computation  of  the 
standardized  measure  of  discounted  future  net  cash  flows  on  a  pre-tax  basis.  PV-10  is  equal  to  the  standardized 
measure  of  discounted  future  net  cash  flows  at  the  applicable  date,  before  deducting  future  income  taxes, 
discounted at 10 percent. We believe that the presentation of PV-10 is relevant and useful to investors because it 
presents the discounted future net cash flows attributable to our estimated net proved reserves prior to taking into 
account future corporate income taxes, and it is a useful measure for evaluating the relative monetary significance 
of our oil and natural gas properties. Further, investors may utilize the measure as a basis for comparison of the 
relative size and value of our reserves to other companies without regard to the specific tax characteristics of such 
entities. We use this measure when assessing the potential return on investment related to our oil and natural gas 
properties. PV-10, however, is not a substitute for the standardized measure of discounted future net cash flows. 
Our PV-10 measure and the standardized measure of discounted future net cash flows do not purport to represent 
the fair value of our oil and natural gas reserves.

The following table provides a reconciliation of the standardized measure of discounted future net cash flows 

to PV-10 of our proved reserves at December 31, 2018, 2017, and 2016.

For the tax years ended December 31, 2017 and 2016, we were not a taxpaying entity for federal income tax purposes, we were not subject 
to  federal  or  state  income  taxes  and  thus  made  no  provision  for  federal  or  state  income  taxes  in  the  calculation  of  our  standardized 
measure.

Changes in Proved Developed Reserves 

Our proved developed reserves as of December 31, 2018 increased by 61.8 MMBoe to 115.5 MMBoe from 

53.7 MMBoe at December 31, 2017, a 115% increase. This increase was due to:  

• acquisitions of 58.0 MMBoe from the Stone Combination and 3.5 MMBoe from the Whistler Acquisition, 
for  more  information,  see  Part  II,  Item  8.  Financial  Statements  and  Supplementary  Data  —  Note  3  — 
Acquisitions;

• Positive revisions of 4.5 MMboe; 

• Proved undeveloped reserves (“PUD”) conversions of 10.0 MMBoe 

• extensions and discoveries of 2.5 MMBoe primarily attributable to wells drilled in Ewing Bank Block 305 

(1.3 MMBoe) and Ship Shoal Block 224 (0.5 MMBoe); and offset by

• production of 16.7 MMBoe

Our PUD reserves at December 31, 2018 decreased by 10.7 MMBoe, or 23% primarily due to: 

Extensions and Discoveries. We added 3.1 MMBoe of PUD reserves through an evaluation of Green Canyon 
Block  18  which  was  initially  acquired  in  the  Whistler  Acquisition.  See  Part  II,  Item  8.  Financial  Statements  and 
Supplementary Data — Note 3 — Acquisitions, for more information.

Revisions  of  Previous  Estimates.  Downward  reserves  revisions  of  4.5  MMBoe  primarily  due  to  timing  of 
development  of  certain  PUD  locations  to  move  beyond  5  years  of  3.3  MMBoe  and  downward  revisions  of  1.2 
MMBoe.  The  revisions  were  caused  by  a  new  geological  data  and  changes  in  overall  project  economics,  and 
expiration of a block. Future development costs related to the PUD revisions decreased by $4.0 million primarily 
due to a review of completion strategy and optimization of capital expenditures in the Phoenix Field.

Acquired. We added a 0.7 MMBoe PUD reserves in Bayou Hebert Field through the Stone Combination.

Conversion to Proved Developed Producing. 2017 PUD to proved developed conversions of 10.0 MMBoe 
are  primarily  attributable  to  the  Phoenix  Field,  Tornado  #3ST  and  two  wells  in  Main  Pass  Block  74,  A8ST  and 
A11ST.

We  annually  review  all  PUD  reserves  to  ensure  an  appropriate  plan  for  development  exists.  Our  PUD 
reserves  are  required  to  be  converted  to  proved  developed  reserves  within  five  years  of  the  date  they  are  first 
booked  as  PUD  reserves.  Future  development  costs  associated  with  our  PUD  reserves  at  December 31,  2018 
totaled approximately $396.7 million, primarily attributable the Phoenix Field’s $317.3 million future development 
costs.  When  considering  capital  expenditures  associated  with  other  exploration  projects  and  abandonment 
obligations, we expect to fund the development of PUD reserves using cash flows from operations and, if needed, 
availability under the Bank Credit Facility, in each future annual period prior to the five year expiration. Our 2019 
drilling  program  includes  development  of  PUD  reserves,  and  the  conversion  rate  may  not  be  uniform  due  to 
obligatory wells, newly acquired PUD reserves and production performance targets.

At  December 31,  2018,  2017  and  2016,  proved  oil,  natural  gas  and  NGL  reserves  attributable  to  our  net 
interests  in  oil  and  natural  gas  properties  were  estimated  and  compiled  for  reporting  purposes  by  our  reservoir 
engineers  and  audited  by  Netherland,  Sewell  &  Associates,  Inc.  (“NSAI”),  independent  petroleum  engineers  and 
geologists, as described in further detail below.

Our policies regarding internal controls over the determination of reserves estimates require reserves reserve 
quantities, reserves categorization, future producing rates, future net revenue and the present value of such future 
net revenue to prepared using the definitions set forth in Regulation S-X, Rule 4-10(a) and subsequent SEC staff 
interpretations  and  guidance.  These  internal  controls,  which  are  intended  to  ensure  reliability  of  our  reserves 
estimations, include, but are not limited to, the following: 

• Reserve  information,  as  well  as  models  used  to  estimate  such  reserves,  is  stored  on  secure  database 
applications to which only authorized personnel are given access rights consistent with their assigned job 
function. 

• A comparison of historical expenses is made to the lease operating costs in the reserve database. 

•

Internal  reserves  estimates  are  reviewed  by  well  and  by  area  by  our  reservoir  engineers.  A  variance 
analysis by well to the previous year-end reserve report is performed. 

• Reserve  estimates  are  reviewed  and  approved  by  certain  members  of  senior  management,  including  our 

President and Chief Executive Officer. 

• We  engaged  NSAI  to  perform  an  independent  audit  of  our  processes  and  the  reasonableness  of  our 
estimates  of  proved  reserves  at  December 31,  2018,  2017  and  2016.  Our  management  requires  that  the 
independent  petroleum  engineers  and  geologist’s  and  our  reserve  quantities  and  calculation  of  the  net 
present value of the reserves, collectively, vary by no more than 10% in the aggregate, in accordance with 
SPEE auditing standards. 

• Data is transferred to NSAI through a secure file transfer protocol site. 

• Material reserve variances are discussed among NSAI, as applicable, our internal reservoir engineers and 

our Director of Reserves to ensure the best estimate of remaining reserves. 

Because  these  estimates  depend  on  many  assumptions,  any  or  all  of  which  may  differ  substantially  from 
actual  results,  reserve  estimates  may  be  different  from  the  quantities  of  oil,  natural  gas  and  NGLs  that  are 
ultimately recovered. 

During the reserves audit, NSAI did not independently verify the accuracy and completeness of information 
and data furnished by us with respect to ownership interests, oil, natural gas and NGL production, well test data, 
historical  costs  of  operation  and  development,  product  prices  or  any  agreements  relating  to  current  and  future 
operations of the fields and sales of production. However, if in the course of the examination something came to 
the attention of NSAI that brought into question the validity or sufficiency of any such information or data, NSAI 
did  not  rely  on  such  information  or  data  until  it  had  satisfactorily  resolved  its  questions  relating  thereto  or  had 
independently verified such information or data. When compared on a well by well basis, some of our estimates are 
greater and some are less than the estimates of NSAI. Given the inherent uncertainties and judgments that go into 
estimating  proved  reserves,  differences  between  internal  and  external  estimates  are  to  be  expected.  NSAI 
determined that its estimates of reserves have been prepared in accordance with the definitions and regulations of 
the SEC, including the criteria of “reasonable certainty,” as it pertains to expectations about the recoverability of 
reserves in future years, under existing economic and operating conditions, consistent with the definition in Rule 4-
10(a)(24)  of  Regulation  S-X.  NSAI  issued  unqualified  audit  opinions  on  our  reserves  as  of  December 31,  2018, 
2017 and 2016 based upon its evaluations. NSAI concluded that our estimates of reserves were, in the aggregate, 
reasonable and have been prepared in accordance with Standards Pertaining to the Estimating and Auditing of Oil 
and Gas Reserves Information promulgated by the SPEE. The NSAI reports are filed as exhibits this report.

Technologies Used in Reserve Estimation 

The SEC’s reserves rules allow the use of techniques that have been proved effective by actual production 
from projects in the same reservoir or an analogous reservoir or by other evidence using reliable technology that 
establishes  reasonable  certainty.  The  term  “reasonable  certainty”  implies  a  high  degree  of  confidence  that  the 
quantities  of  oil,  natural  gas  and/or  NGLs  actually  recovered  will  equal  or  exceed  the  estimate.  To  achieve 
reasonable certainty, our internal reservoir engineers employed technologies that have been demonstrated to yield 
results with consistency and repeatability. The technologies and economic data used in the estimation of our proved 
reserves  include,  but  are  not  limited  to,  well  logs,  geologic  maps,  seismic  data,  well  test  data,  production  data, 
historical  price  and  cost  information  and  property  ownership  interests.  The  accuracy  of  the  estimates  of  our 
reserves is a function of: 

•

the quality and quantity of available data and the engineering and geological interpretation of that data; 

• estimates regarding the amount and timing of future operating costs, development costs and workovers, all 

of which may vary considerably from actual results; 

•

•

future prices of oil, natural gas and NGLs, which may vary considerably from those mandated by the SEC; 
and 

the judgment of the persons preparing the estimates.

As of December 31, 2018, two exploratory and appraisal wells have been excluded from the table until a determination is made if the wells 
have  found  proved  reserves.  Also  excluded  from  the  table  are  two  development  wells  awaiting  completion.  These  wells  are  shown  as 
“Wells Suspended or Waiting on Completion” in the table below.

A productive well is an exploratory or development well found to be capable of producing either oil or natural gas in sufficient quantities 
to justify completion as an oil or natural gas producing well. Productive wells are included in the table in the year they were determined to 
be productive, as opposed to the year the well was drilled.

A dry well is an exploratory or development well that is not a productive well. Dry wells are included in the table in the year they were 
determined not to be productive well, as opposed to the year the well was drilled.

Undeveloped  acreage  is  considered  to  be  those  leased  acres  on  which  wells  have  not  been  drilled  or 
completed to a point that would permit the production of commercial quantities of oil and natural gas regardless of 
whether or not such acreage contains proved reserves. Included within undeveloped acreage are those leased acres 
(held by production under the terms of a lease) that are not within the spacing unit containing, or acreage assigned 
to,  the  productive  well  holding  such  lease.  The  terms  of  our  leases  on  undeveloped  acreage  as  of  December 31,

Expenditures and Costs Incurred 

For  information  on  property  development,  exploration  and  acquisition  costs,  see  Part  II,  Item  8.  Financial 

Statements and Supplementary Data — Note 14 — Supplemental Oil and Gas Disclosures. 

Title to Properties 

We believe that we have satisfactory title to our oil and natural gas properties in accordance with generally 
accepted  industry  standards.  Individual  properties  may  be  subject  to  burdens  such  as  royalty,  overriding  royalty, 
and  carried,  net  profits,  working  and  other  outstanding  interests  customary  in  the  industry.  In  addition,  interests 
may  be  subject  to  obligations  or  duties  under  applicable  laws  or  burdens  such  as  production  payments,  ordinary 
course  liens  incidental  to  operating  agreements  and  for  current  taxes  and  development  obligations  under  oil  and 
natural gas leases. As is customary in the industry in the case of undeveloped properties, often limited investigation 
of record title is made at the time of acquisition. Title search investigations are made prior to the consummation of 
an acquisition of producing properties and before commencement of drilling operations on undeveloped properties. 
To  the  extent  title  opinions  or  other  investigations  reflect  defects  affecting  such  undeveloped  properties,  we  are 
typically responsible for curing any such title defects at our expense. 

Commodity Price Risks and Price Risk Management Activities 

Production from our properties is marketed using methods that are consistent with industry practices. Sales 
prices for oil and natural gas production are negotiated based on factors normally considered in the industry, such 
as  an  index  or  spot  price,  price  regulations,  distance  from  the  well  to  the  pipeline,  commodity  quality  and 
prevailing supply and demand conditions. We enter into derivative contracts on our oil and natural gas production 
primarily  to  stabilize  cash  flows  and  reduce  the  risk  and  financial  impact  of  downward  commodity  price 
movements  on  commodity  sales.  For  additional  information  regarding  our  commodity  price  risk  and  commodity 
derivative instruments, see Part II, Item 7A — Quantitative and Qualitative Disclosures About Market Risk.

Significant Customers 

Oil and natural gas companies spend capital on exploration, drilling and production operations expenditures, 
the amount of which is generally dependent on the prevailing view of future oil and natural gas prices which are 
subject  to  many  external  factors  which  may  contribute  to  significant  volatility  in  future  prices.  We  market 
substantially all of our oil, natural gas and NGL production from the properties we operate and those we do not 
operate.  Our  customers  consist  primarily  of  major  oil  and  gas  companies,  well-established  oil  and  pipeline 
companies and independent oil and natural gas producers and suppliers. We perform ongoing credit evaluations of 
our customers and provide allowances for probable credit losses when necessary. For the year ended December 31, 
2018, 65% and 18% of our oil, natural gas and NGL revenues were attributable to Shell Trading (US) Company 
and Phillips 66, respectively, which are the customers that individually represented 10% or more of our oil, natural 
gas and NGL revenues. 

Competitive Conditions 

The oil and natural gas business is highly competitive in the exploration for and acquisition of reserves, the 
acquisition of oil and natural gas leases, equipment and personnel required to find and produce reserves and in the 
gathering  and  marketing  of  oil,  natural  gas  and  NGLs.  We  compete  with  large  integrated  oil  and  natural  gas 
companies  as  well  as  independent  exploration  and  production  companies.  Certain  of  our  competitors  may  have 
significantly  more  financial  or  other  resources  available  to  them.  In  addition,  certain  of  the  larger  integrated 
companies  may  be  better  able  to  respond  to  industry  changes,  including  price  fluctuation,  oil  and  natural  gas 
demand and governmental regulations. 

However,  we  believe  our  high  quality  oil-weighted  production  base,  proven  expertise  in  utilizing  seismic 
technology to identify, evaluate and develop exploitation and exploration opportunities, balanced mix of assets in 
the Gulf of Mexico deep and shallow waters and significant operating control give us a strong competitive position 
relative to many of our competitors. 

Seasonality of Business 

Weather  conditions  affect  the  demand  for,  and  prices  of,  oil  and  natural  gas.  Due  to  these  seasonal 
fluctuations, our results of operations for individual quarterly periods may not be indicative of the results that may 
be realized on an annual basis. Generally, but not always, the demand for gas decreases during the summer months 
and  increases  during  the  winter  months.  Seasonal  anomalies  such  as  mild  winters  or  hot  summers  may  impact 
general seasonal changes in demand.

Insurance Matters 

Our oil and natural gas operations are subject to risks incident to the operation of oil and gas wells, including 
but  not  limited  to  uncontrolled  flows  of  oil,  gas,  brine  or  well  fluids  into  the  environment,  blowouts,  cratering, 
mechanical  difficulties,  fires,  explosions  or  other  physical  damage,  pollution  or  other  risks,  any  of  which  could 
result in substantial losses to us. In addition, our oil and natural gas properties are located in the Gulf of Mexico, 
which makes us more vulnerable to tropical storms and hurricanes. These hazards can cause personal injury or loss 
of life, severe damage to and destruction of property and equipment, pollution or environmental damage and the 
suspension  of  operations.  Damages  arising  from  such  occurrences  may  result  in  lawsuits  asserting  large  claims. 
Insurance  may  not  be  sufficient  or  effective  under  all  circumstances  or  against  all  hazards  to  which  we  may  be 
subject. A successful claim for which we are not fully insured could have a material adverse effect on our financial 
condition, results of operations and cash flow. Although we obtain insurance against some of these risks, we cannot 
insure against all possible losses. As a result, any damage or loss not covered by insurance could have a material 
adverse effect on our financial condition, results of operations and cash flow. 

We have insurance policies to cover some of our risk of loss associated with our operations, and we maintain 
the  amount  of  insurance  we  believe  is  prudent.  However,  not  all  of  our  business  activities  can  be  insured  at  the 
levels we desire because of either limited market availability or unfavorable economics (limited coverage for the 
underlying cost). 

Our  general  property  damage  insurance  provides  varying  ranges  of  coverage  based  upon  several  factors, 
including  well  counts  and  the  cost  of  replacement  facilities.  Our  general  liability  insurance  program  provides  a 
limit  of  $500 million  for  each  occurrence  and  in  the  aggregate,  and  includes  varying  deductibles.  Our  Offshore 
Pollution Act insurance is subject to a maximum of up to $150 million for each occurrence and in the aggregate, 
including  a  $100,000  retention.  Coverage  is  provided  for  damage  to  our  assets  resulting  from  a  named  Gulf  of 
Mexico windstorm; however, such coverage is subject to a maximum of $155 million per named windstorm and in 

21

6696_10K.pdf

the aggregate, and is also subject to a maximum of $25 million per occurrence retention. We separately maintain an 
operators  extra  expense  policy  with  additional  coverage  for  an  amount  up  to  $500 million  for  Gulf  of  Mexico 
deepwater  drilling  wells,  $150 million  for  Gulf  of  Mexico  shelf  drilling  wells,  $75 million  for  Gulf  of  Mexico 
producing and shut-in wells, $50 million for drilling and workover in inland waters and $25 million for drilling and 
workover in onshore fields that would cover costs involved in making a well safe after a blow-out or getting the 
well under control; re-drilling a well to the depth reached prior to the well being out of control or blown out; costs 
for  plugging  and  abandoning  the  well;  and  costs  for  clean-up  and  containment  and  for  damages  caused  by 
contamination  and  pollution.  For  our  Mexico  insurance  policies,  we  maintain  $250 million  in  operators  extra 
expense coverage for operations and $500 million per occurrence and aggregate limit for general liability.

We  may  increase  or  decrease  insurance  coverage  around  our  key  strategic  assets,  including  potentially 
purchasing  catastrophic  bond  instruments.  Our  highest  value  assets,  which  are  located  in  the  Phoenix  Field, 
produce through the HP-I floating production system, which has the capability to disconnect and move away in the 
event of a storm, mitigating the risk of property damage. 

We customarily have reciprocal agreements with our customers and vendors in which each contracting party 
is responsible for its respective personnel for liability related to work performed for us. Under these agreements, we 
generally  are  indemnified  against  third  party  claims  related  to  the  injury  or  death  of  our  customers’  or  vendors’ 
personnel, subject to the application of various states’ laws. 

Government Regulation 

Exploration  and  development  and  the  production  and  sale  of  oil,  natural  gas  and  NGLs  are  subject  to 
extensive federal, state, local and foreign regulations. An overview of these regulations is set forth below. We do 
not believe that compliance with existing requirements will have a material adverse effect on our financial position, 
results  of  operations  or  cash  flows.  However,  current  regulatory  requirements  may  change,  currently  unforeseen 
environmental  incidents  may  occur  or  past  non-compliance  with  environmental  laws  or  regulations  may  be 
discovered. Because such rules and regulations are frequently amended or reinterpreted, we are unable to predict 
the future cost or impact of complying with such laws. Although the regulatory burden on the oil and natural gas 
industry increases our cost of doing business and, consequently, affects our profitability, these burdens generally do 
not affect us any differently or to any greater or lesser extent than they affect others in our industry with similar 
types, quantities and locations of production. 

General Overview 

Our oil and natural gas operations are subject to various federal, state, local and foreign laws and regulations. 

Generally speaking, these regulations relate to matters that include, but are not limited to: 

•

location of wells; 

• size of drilling and spacing units or proration units; 

• number of wells that may be drilled in a unit; 

• unitization or pooling of oil and natural gas properties; 

• drilling and casing of wells; 

•

issuance of permits in connection with exploration, drilling and production; 

• well production; 

• spill prevention plans; 

• protection of private and public surface and ground water supplies; 

• emissions permitting or limitations; 

• protection of endangered species; 

• use, transportation, storage and disposal of fluids and materials incidental to oil and natural gas operations; 

• surface usage and the restoration of properties upon which wells have been drilled; 

• calculation and disbursement of royalty payments and production taxes; 

22

6696_10K.pdf

•

requirements  for  the  posting  of  supplemental  bonds  or  providing  other  forms  of  financial  assurance  for 
P&A obligations; 

• plugging and abandoning of wells; and 

•

transportation of production. 

Outer Continental Shelf (“OCS”) Regulation. Our operations on federal oil and natural gas leases in the Gulf 
of  Mexico  are  subject  to  regulation  by  the  Bureau  of  Safety  and  Environmental  Enforcement  (“BSEE”)  and  the 
Bureau  of  Ocean  Energy  Management  (“BOEM”),  both  agencies  of  the  U.S.  Department  of  the  Interior  (“DOI). 
These  leases  contain  relatively  standardized  terms  and  require  compliance  with  detailed  BSEE  and  BOEM 
regulations and orders issued pursuant to various federal laws, including the federal Outer Continental Shelf Lands 
Acts (“OCSLA”). These laws and regulations are subject to change, and many new requirements, including those 
related  to  safety,  permitting  and  performance,  were  imposed  by  BSEE  and  BOEM  subsequent  to  the 2010 
Deepwater  Horizon  incident.  For  offshore  operations,  lessees  must  obtain  BOEM  approval  for  exploration, 
development and production plans prior to the commencement of such operations. In addition to permits required 
from other agencies such as the U.S Environmental Protection Agency (the “EPA”), lessees must obtain a permit 
from  BSEE  prior  to  the  commencement  of  drilling  and  comply  with  regulations  governing,  among  other  things, 
engineering and construction specifications for production facilities, safety procedures, P&A of wells on the OCS, 
calculation of royalty payments and the valuation of production for this purpose, and removal of facilities. 

These  rules  are  frequently  subject  to  change.  For  example,  in  2016,  BSEE  published  a  final  rule  on  well 
control that, among other things, imposes rigorous standards relating to the design, operation and maintenance of 
blow-out  preventers,  real-time  monitoring  of  deepwater,  high  temperature,  high  pressure  drilling  activities,  and 
enhanced  reporting  requirements.  Pursuant  to  President  Trump’s  Executive  Orders  dated  March 28,  2017,  and 
April 28,  2017  (the  “Executive  Orders”),  BSEE  initiated  a  review  of  the  well  control  regulations  to  determine 
whether  the  rules  are  consistent  with  the  stated  policy  of  encouraging  energy  exploration  and  production,  while 
ensuring  that  any  such  activity  is  safe  and  environmentally  responsible.  In  October 2017,  BSEE  announced,  in  a 
report published by the DOI, that it is considering several revisions to the regulations and that it is in the process of 
determining the most effective way to engage stakeholders in the process. In another example, the BSEE published 
a final rule in September 2018 amending its production safety systems regulations, which includes the imposition 
of operational and design standards and the removal of the requirement of offshore operators to certify through an 
independent third party that their critical safety and pollution prevention equipment (e.g. subsea safety equipment, 
including blowout preventers) is operation and functioning as designed in the most extreme conditions.

In a third example, BOEM published a proposed rule in April 2016 that would update existing air emissions 
requirements relating to offshore oil and natural gas activity on the OCS. BOEM regulates these air emissions in 
connection  with  its  review  of  exploration  and  development  plans,  rights  of  way  (“ROWs”)  and  rights  of  use 
(“RUEs”)  applications.  The  proposed  rule  would  bolster  existing  air  emissions  requirements  by,  among  other 
things, requiring the reporting and tracking of the emissions of all pollutants defined by the EPA to affect human 
health and public welfare. Pursuant to the Executive Orders, BOEM is reviewing the proposed air quality rule. In 
October 2017,  the  DOI  announced  that  it  is  currently  reviewing  recommendations  on  how  to  proceed,  including 
promulgating  final  rules  for  certain  necessary  provisions  and  issuing  a  new  proposed  rule  that  may  withdraw 
certain provisions and seek additional input on others. 

Compliance  with  new  and  future  regulations  could  result  in  significant  costs,  including  increased  capital 
expenditures  and  operating  costs,  and  could  adversely  impact  our  business.  In  addition,  under  certain 
circumstances,  BSEE  may  require  our  operations  on  federal  leases  to  be  suspended  or  terminated.  Any  such 
suspension or termination could adversely affect our financial condition and operations. 

Furthermore,  hurricanes  in  the  Gulf  of  Mexico  can  have  a  significant  impact  on  oil  and  natural  gas 
operations. The effects from past hurricanes have included structural damage to fixed production facilities, semi-
submersibles and jack-up drilling rigs. BOEM and BSEE continue to be concerned about the loss of these facilities 
and rigs as well as the potential for catastrophic damage to key infrastructure and the resultant pollution from future 
storms. In an effort to reduce the potential for future damage, BOEM and BSEE have periodically issued guidance 
aimed  at  improving  platform  survivability  by  taking  into  account  environmental  and  oceanic  conditions  in  the 
design  of  platforms  and  related  structures.  It  is  possible  that  similar,  if  not  more  stringent,  requirements  will  be 
issued by BOEM and BSEE for future hurricane seasons. New requirements, if any, could increase our operating 
costs and/or capital expenditures. 

23

6696_10K.pdf

In  addition,  in  order  to  cover  the  various  decommissioning  obligations  of  lessees  on  the  OCS,  BOEM 
generally requires that lessees post some form of acceptable financial assurances that such obligations will be met, 
such as surety bonds. The cost of such bonds or other financial assurance can be substantial, and we can provide no 
assurance that we can continue to obtain bonds or other surety in all cases. For example, in the Notice to Lessees 
and  operators  (“NTL”)  #2016-N01  (the  “2016  NTL”),  BOEM  announced  updated  financial  assurance  and  risk 
management requirements for offshore leases. The 2016 NTL details procedures to determine a lessee’s ability to 
carry  out  its  lease  obligations—primarily  the  decommissioning  of  facilities—and  whether  to  require  lessees  to 
furnish additional financial assurance to meet BOEM’s estimate of the lessees decommissioning obligations. The 
2016 NTL supersedes the agency’s prior practice of allowing operators of a certain net worth to waive the need for 
supplemental  bonds  and  provides  updated  criteria  for  determining  a  lessee’s  ability  to  self-insure  only  a  small 
portion of its OCS liabilities based upon the lessee’s financial capacity and financial strength. The 2016 NTL also 
allows lessees to meet their additional financial security requirements pursuant to an individually approved tailored 
plan, whereby an operator and BOEM agree to set a timeframe for the posting of additional financial assurances. 
The 2016 NTL became effective in September 2016, but the BOEM has since extended indefinitely beyond June 
30, 2017 the start date for implementation of this NTL, except for certain circumstances where there is a substantial 
risk of nonperformance of the interest holder’s decommissioning liabilities, so as to provide BOEM with time to 
review its complex financial assurance program.

In late 2016, we received orders from BOEM to provide additional financial assurance in material amounts 
relating to our OCS properties (the “BOEM 2016 Orders”). We entered into discussions with BOEM regarding the 
requested additional financial security and submitted a proposed tailored plan for the posting of additional financial 
security  to  the  agency  for  review.  However,  the  BOEM  has  indefinitely  delayed  beyond  June  30,  2017 
implementation  of  the  2016  NTL,  has  rescinded  the  BOEM  2016  Orders  while  BOEM  reviews  its  financial 
assurance  program  and,  to  date,  has  taken  no  action  with  respect  to  our  previously  submitted  proposed  tailored 
plan.

We remain in active discussions with our government regulators and our industry peers with regard to any 
future  rule  making  and  financial  assurance  requirements.  The  BOEM  is  continuing  to  review  and  reconsider  its 
financial assurance program and thus the amounts of any financial assurance that may be demanded by the agency 
is  uncertain  at  this  time.  Notwithstanding  the  2016  NTL,  BOEM  may  also  bolster  its  financial  assurance 
requirements  mandated  by  rule  for  all  companies  operating  in  federal  waters.  The  BOEM  could  also  make  new 
demands for additional financial assurance in material amounts in the event the agency chooses to implement the 
2016  NTL.    Such  demands  could  exceed  our  ability  to  provide  any  additional  financial  assurance  that  may  be 
required  by  BOEM  in  the  future.  The  future  cost  of  compliance  with  our  existing  supplemental  bonding 
requirements, including the obligations imposed upon us as a result of the 2016 NTL, to the extent implemented, as 
well  as  any  other  future  BOEM  directives,  or  any  other  changes  to  BOEM’s  rules  applicable  to  our  or  our 
subsidiaries’  properties,  could  materially  and  adversely  affect  our  financial  condition,  cash  flows,  and  results  of 
operations. 

Regulation  in  Shallow  Waters  Off  the  Coast  of  Mexico.  Our  operations  on  oil  and  natural  gas  blocks  in 
shallow waters off the coast of Mexico’s Veracruz and Tabasco states, and in other Mexican offshore areas where 
we are assessing other exploration opportunities, are subject to regulation by SENER, the CNH and other Mexican 
regulatory bodies. The CNH is responsible for, among other things, overseeing the tender procedures for awarding 
contracts for the exploration and production of oil and natural gas in Mexican waters, managing and supervising 
contracts  that  have  been  awarded,  and  approving  exploration  and  production  plans.  The  PSCs  that  we  and  our 
consortium partners have entered into for the development of these acreages contain terms that impose on us the 
duty  to  comply  with  various  laws  and  regulations.  These  laws  and  regulations  govern,  among  other  things,  the 
exploration  and  exploitation  of  hydrocarbons  (including  certain  national  content  requirements),  the  treatment, 
conveyance,  marketing,  transport  and  storage  of  petroleum,  and  requirements  for  industrial  safety,  operational 
security,  and  facility  decommissioning.  Failure  to  comply  can  result  in  the  imposition  of  monetary  penalties, 
revocation of permits, rescission of the relevant PSC, suspension of operations, and ordered decommissioning of 
offshore  facilities  and  systems.  The  laws  and  regulations  governing  activities  in  the  Mexican  energy  sector  are 
relatively new, having been significantly reformed in 2013, and the legal regulatory framework continues to evolve 
as SENER, the CNH and other Mexican regulatory bodies issue new regulations and guidance. Such regulations 
are subject to change, and it is possible that SENER, the CNH or other Mexican regulatory bodies may impose new 
or  revised  requirements  that  could  increase  our  operating  costs  and/or  capital  expenditures  for  operations  in 
Mexican offshore waters.

Environmental Regulations 

We  are  subject  to  various  federal,  state,  local  and  foreign  regulations  concerning  occupational  safety  and 
health as well as the discharge of materials into, and the protection of, the environment. Environmental laws and 
regulations relate to, among other things: 

• assessing the environmental impact of seismic acquisition, drilling or construction activities; 

•

•

•

the generation, storage, transportation and disposal of waste materials; 

the emission of certain gases into the atmosphere; 

the  monitoring,  abandonment,  reclamation  and  remediation  of  well  and  other  sites,  including  sites  of 
former operations; 

• various environmental permitting requirements, such as permits for wastewater discharges; 

•

the development of emergency response and spill contingency plans; and 

• protection of private and public surface and ground water supplies. 

Based on regulatory trends and increasingly stringent laws, our capital expenditures and operating expenses 
related to the protection of the environment and safety and health compliance have increased over the years and it 
is possible such expenses will continue to increase. We cannot predict with any reasonable degree of certainty our 
future exposure concerning such matters and the cost of compliance could be significant. Failure to comply with 
these  laws  and  regulations  may  result  in  the  assessment  of  administrative,  civil  and  criminal  penalties,  the 
imposition of remedial obligations, natural resource damages or the issuance of injunctive relief (including orders 
to cease operations). Both onshore and offshore drilling in certain areas has been opposed by environmental groups 
and,  in  certain  areas,  has  been  restricted.  Moreover,  some  environmental  laws  and  regulations  may  impose  strict 
liability,  which  could  subject  us  to  liability  for  conduct  that  was  lawful  at  the  time  it  occurred  or  conduct  or 
conditions caused by prior operators or third parties. To the extent laws are enacted or other governmental action is 
taken that prohibits or restricts onshore or offshore drilling or imposes environmental protection requirements that 
result in increased costs to the oil and gas industry in general, our business and financial results could be adversely 
affected. 

We  expect  to  continue  making  expenditures  on  a  regular  basis  relating  to  environmental  compliance.  We 
maintain insurance coverage for spills, pollution and certain other environmental risks, although we are not fully 
insured  against  all  such  risks.  Our  insurance  coverage  provides  for  the  reimbursement  to  us  of  certain  costs 
incurred for the containment and clean-up of materials that may be suddenly and accidentally released in the course 
of our operations, but such insurance does not fully insure against pollution and similar environmental risks. We do 
not anticipate that we will be required under current environmental laws and regulations to expend amounts that 
will  have  a  material  adverse  effect  on  our  consolidated  financial  position  or  our  results  of  operations.  However, 
since environmental costs and liabilities are inherent in our operations and in the operations of companies engaged 
in similar businesses and since regulatory requirements frequently change and may become more stringent, there 
can be no assurance that material costs and liabilities will not be incurred in the future. Such costs may result in 
increased costs of operations and acquisitions and decreased production. 

Water Discharges. Our discharges into waters of the United States are limited by the federal Clean Water Act 
(“CWA”) and analogous state laws. The CWA prohibits any discharge of pollutants, including spills and leaks of 
oil and other substances, into waters of the United States, except in compliance with permits issued by federal and 
state governmental agencies. These discharge permits also include monitoring and reporting obligations. Failure to 
comply with the CWA, including discharge limits set by permits issued pursuant to the CWA, may also result in 
administrative, civil or criminal enforcement actions. Violations of the CWA can result in suspension, debarment 
or  the  imposition  of  statutory  disability,  each  of  which  prevents  companies  and  individuals  from  participating  in 
government  contracts  and  receiving  some  non-procurement  government  benefits.  The  CWA  also  requires  the 
preparation of oil spill response plans and spill prevention, control and countermeasure plans. 

25

6696_10K.pdf

Oil  Pollution  Act.  The  Oil  Pollution  Act  of  1990  (“OPA”)  holds  owners  and  operators  of  offshore  oil 
production or handling facilities, including the lessee or permittee of the area where an offshore facility is located, 
strictly liable for the costs of removing oil discharged into waters of the United States and for certain damages from 
such  spills.  OPA  assigns  joint  and  several  strict  liability,  without  regard  to  fault,  to  each  liable  party  for  all 
containment and oil removal costs and a variety of public and private damages including, but not limited to, the 
costs  of  responding  to  a  release  of  oil,  natural  resource  damages  and  economic  damages  suffered  by  persons 
adversely  affected  by  an  oil  spill.  Although  defenses  exist  to  the  liability  imposed  by  OPA,  they  are  limited.  In 
addition, in January 2018, BOEM raised OPA’s damages liability cap to $137.7 million; however, a party cannot 
take  advantage  of  liability  limits  if  a  spill  was  caused  by  gross  negligence  or  willful  misconduct,  resulted  from 
violation of a federal safety, construction or operating regulation, or if the party failed to report a spill or cooperate 
fully  in  the  clean-up.  OPA  also  requires  responsible  parties  to  maintain  evidence  of  financial  responsibility  in 
prescribed  amounts.  OPA  currently  requires  a  minimum  financial  responsibility  demonstration  of  between 
$35 million  to  $150 million  for  companies  operating  on  the  OCS,  although  BOEM  may  increase  this  amount  in 
certain  situations.  From  time  to  time,  the  United  States  Congress  has  proposed  amendments  to  OPA  raising  the 
financial responsibility requirements. If OPA is amended to increase the minimum level of financial responsibility, 
we  may  experience  difficulty  in  providing  financial  assurances  sufficient  to  comply  with  this  requirement.  We 
cannot predict at this time whether OPA will be amended or whether the level of financial responsibility required 
for  companies  operating  on  the  OCS  will  be  increased.  In  any  event,  if  an  oil  discharge  or  substantial  threat  of 
discharge were to occur, we may be liable for costs and damages, which costs and liabilities could be material to 
our results of operations and financial position. 

National  Environmental  Policy  Act.  The  National  Environmental  Policy  Act  (“NEPA”)  requires  federal 
agencies, including the DOI, to consider the impacts their actions have on the human environment, and to prepare 
detailed  statements  for  major  federal  actions  having  the  potential  to  significantly  impact  the  environment.  These 
requirements can lead to additional costs and delays in permitting for operators as the DOI or its bureaus may need 
to  prepare  Environmental  Assessments  (“EA”)  and  more  detailed  Environmental  Impact  Statements  (“EIS”)  in 
support  of  its  leasing  and  other  activities  that  have  the  potential  to  significantly  affect  the  quality  of  the 
environment. If the EA indicates that no significant impact is likely, then the agency can release a finding of no 
significant impact and carry on with the proposed action. Otherwise, the agency must then conduct a full-scale EIS. 
The NEPA process involves public input through comment. These comments, as well as the agency’s analysis of 
the proposed project, can result in changes to the nature of a proposed project, such as by limiting the scope of the 
project or requiring resource-specific mitigation. The adequacy of the agency’s NEPA process can be challenged in 
federal  court  by  process  participants.  This  process  may  result  in  delaying  the  permitting  and  development  of 
projects, and result in increased costs. 

Endangered Species Act. The Endangered Species Act (“ESA”) restricts activities that may affect federally 
identified  endangered  and  threatened  species  or  their  habitats.  Additionally,  the  Migratory  Bird  Treaty  Act 
(“MBTA”) implements various treaties and conventions between the United States and certain other nations for the 
protection  of  migratory  birds.  Under  the  MBTA,  the  taking,  killing  or  possessing  of  migratory  birds  is  unlawful 
without a permit. The Marine Mammal Protection Act similarly prohibits the taking of marine mammals without 
authorization. We conduct operations on oil and natural gas leases in areas where certain species that are protected 
by  the  ESA,  MBTA  and  Marine  Mammal  Protection  Act  are  known  to  exist  and  where  other  species  that 
potentially  could  be  protected  under  these  statutes.  The  U.S.  Fish  and  Wildlife  Service  or  the  National  Marine 
Fisheries  Service  may  designate  critical  habitat  that  it  believes  is  necessary  for  survival  of  a  threatened  or 
endangered species. A critical habitat designation could result in further material restrictions to federal land use and 
may materially delay or prohibit access to protected areas for oil and natural gas development. These statutes may 
result in operating restrictions or a temporary, seasonal or permanent ban in affected areas. 

Hazardous  Substances  and  Waste  Management.  The  Resource  Conservation  and  Recovery  Act  (“RCRA”) 
generally  regulates  the  disposal  of  solid  and  hazardous  wastes  and  imposes  certain  environmental  cleanup 
obligations.  Although  RCRA  specifically  excludes  from  the  definition  of  hazardous  waste  “drilling  fluids, 
produced waters and other wastes associated with the exploration, development or production of crude oil, natural 
gas  or  geothermal  energy,”  the  EPA  and  state  agencies  may  regulate  these  wastes  as  solid  wastes.  However, 
pursuant  to  a  consent  decree  issued  by  the  U.S.  District  Court  for  the  District  of  Columbia  in  2016,  the  EPA  is 
required  to  propose  no  later  than  March  15,  2019,  a  rulemaking  for  revision  of  certain  Subtitle  D  criteria 
regulations that could result in oil and natural gas exploration and production wastes being regulated as hazardous 
wastes,  or  sign  a  determination  that  revision  of  the  regulations  is  unnecessary.  If  EPA  proposes  rulemaking  for 

26

6696_10K.pdf

revised  oil  and  gas  regulations,  the  consent  decree  requires  that  the  EPA  take  final  action  following  notice  and 
comment rulemaking no later than July 15, 2021. A loss of the RCRA exclusion for drilling fluids, produced waters 
and  related  wastes  could  result  in  increased  costs  to  manage  and  dispose  of  generated  wastes.  Also,  ordinary 
industrial  wastes,  such  as  paint  wastes,  waste  solvents,  laboratory  wastes  and  waste  oils,  may  be  regulated  as 
hazardous waste. 

Comprehensive  Environmental  Response,  Compensation  and  Liability  Act.  Comprehensive  Environmental 
Response,  Compensation  and  Liability  Act  (“CERCLA”)  and  comparable  state  laws  impose  liability,  without 
regard  to  fault  or  the  legality  of  the  original  conduct,  on  persons  that  are  considered  to  have  contributed  to  the 
release of a “hazardous substance” into the environment. Such “responsible persons” may be subject to joint and 
several liability under CERCLA for the costs of cleaning up the hazardous substances that have been released into 
the environment and for damages to natural resources. Further, it is not uncommon for coastal landowners or other 
third parties to file claims for personal injury and property damage allegedly caused by the hazardous substances 
released into the environment. 

Air  Emissions.  The  Clean  Air  Act  (“CAA”)  and  comparable  state  statutes  restrict  the  emission  of  air 
pollutants and affect both onshore and offshore oil and natural gas operations. New facilities may be required to 
obtain separate construction and operating permits before construction work can begin or operations may start, and 
existing  facilities  may  be  required  to  incur  capital  costs  in  order  to  remain  in  compliance.  Also,  the  EPA  has 
developed, and continues to develop, more stringent regulations governing emissions of toxic air pollutants, and is 
considering the regulation of additional air pollutants and air pollutant parameters. For example, in October 2015, 
the EPA lowered the National Ambient Air Quality Standard (“NAAQS”) for ozone from 75 to 70 parts per billion. 
State implementation of the revised NAAQS could result in stricter permitting requirements, delay or prohibit our 
ability  to  obtain  such  permits,  and  result  in  increased  expenditures  for  pollution  control  equipment,  the  costs  of 
which could be significant. 

Worker Health and Safety. The Occupational Safety and Health Act (“OSHA”) and comparable state statutes 
regulate  the  protection  of  the  health  and  safety  of  workers.  The  OSHA  hazard  communication  standard  requires 
maintenance  of  information  about  hazardous  materials  used  or  produced  in  operations  and  provision  of  such 
information to employees. Other OSHA standards regulate specific worker safety aspects of our operations. Failure 
to comply with OSHA requirements can lead to the imposition of penalties. 

Climate  Change.  From  time  to  time,  the  United  States  Congress  has  considered  a  variety  of  tax,  energy-
related  or  environmental  market-based  mechanisms  to  promote  or  induce  the  reduction  of  emissions  of  Green 
House Gasses (“GHG”s) by several commercial or industrial sectors. In addition, more than one half of the states 
already  have  begun  implementing  legal  measures  such  as  renewable  energy  requirements  or  cap  and  trade 
programs to reduce emissions of GHGs. 

Additionally,  the  United  States  is  one  of  almost  200  nations  that,  in  December  2015,  agreed  to  the  Paris 
Agreement,  an  international  climate  change  agreement  in  Paris,  France  that  calls  for  countries  to  set  their  own 
GHG emissions targets and be transparent about the measures each country will use to achieve its GHG emissions 
targets. The Paris Agreement entered into force on November 4, 2016. In June 2017, President Trump stated that 
the United States would withdraw from the Paris Agreement, but may enter into a future international agreement 
related  to  GHGs.  The  Paris  Agreement  provides  for  a  four-year  exit  process  beginning  when  it  took  effect  in 
November 2016, which would result in an effective exit date of November 2020. The United States’ adherence to 
the  exit  process  is  uncertain  and/or  the  terms  on  which  the  United  States  may  reenter  the  Paris  Agreement  or  a 
separately negotiated agreement are unclear at this time. 

In addition, the EPA has determined that emissions of carbon dioxide, methane and other GHGs present an 
endangerment to public health and the environment because emissions of such gases contribute to warming of the 
earth’s atmosphere and other climatic changes. Based on these findings, the EPA began adopting and implementing 
regulations to restrict emissions of GHGs under existing provisions of the federal CAA. The EPA has adopted rules 
regulating  GHG  emissions  under  the  existing  CAA,  including  a  rule  regulating  emissions  of  GHGs  from  certain 
large  stationary  sources  through  preconstruction  and  operating  permit  requirements.  The  EPA  has  also  adopted 
rules requiring the reporting of GHG emissions from specified large GHG emission sources in the United States, on 
an annual basis. Currently, our operations include one active floating production unit (the HP-I,) and our facilities 
at the Ram Powell and Pompano Fields are subject to those EPA GHG reporting requirements. 

27

6696_10K.pdf

The  EPA  has  also  taken  steps  to  limit  methane  emissions,  a  GHG,  from  certain  new  modified  or 
reconstructed  facilities  in  the  oil  and  natural  gas  sector  through  the  adoption  of  a  final  rule  in  June  2016 
establishing Subpart OOOOa standards for methane emissions. However, in 2017, the EPA published a proposed 
rule to stay certain portions of these Subpart OOOOa standards for two years but the rule was not finalized. Rather, 
in  February  2018,  the  EPA  finalized  amendments  to  certain  requirements  of  the  June  2016  final  rule,  and  in 
September  2018  the  EPA  proposed  additional  amendments,  including  rescission  of  certain  requirements  and 
revisions to other requirements, such as fugitive emission monitoring frequency. In the event that the EPA’s June 
2016 rule should remain or be placed in effect, or should any other new methane emission standards be imposed on 
the oil and natural gas sector, such requirements could result in increased costs to our operations as well as result in 
restrictions,  delays  or  cancellations  in  such  operations,  which  costs,  restrictions,  delays  or  cancellations  could 
adversely affect our business.

Environmental Regulation in Shallow Waters Off the Coast of Mexico. Our operations on oil and natural gas 
blocks  in  shallow  waters  off  the  coast  of  Mexico’s  Veracruz  and  Tabasco  states,  and  in  other  Mexican  offshore 
areas  where  we  are  assessing  other  exploration  opportunities,  are  subject  to  regulation  by  the  Mexican  National 
Agency of Industrial Safety and Environmental Protection of the Hydrocarbons Sector (“ASEA”). We must obtain 
ASEA-issued  permits  and  comply  with  ASEA  regulations  governing  hydrocarbon  activities,  including 
requirements  for  environmental  impact  and  risk  assessments,  industrial  safety,  waste  management,  water  and  air 
emissions,  operational  security,  and  facility  decommissioning.  Failure  to  comply  with  applicable  laws  and 
regulations can result in the imposition of monetary penalties, revocation of permits, suspension of operations, and 
ordered decommissioning of offshore facilities and systems. The laws and regulations governing the protection of 
health,  safety,  and  the  environment  from  activities  in  the  Mexican  energy  sector  are  relatively  new,  having  been 
significantly  reformed  in  2013  and  2014,  and  the  legal  regulatory  framework  continues  to  evolve  as  ASEA  and 
other Mexican regulatory bodies issue new regulations and guidance. Such regulations are subject to change, and it 
is  possible  that  ASEA  or  other  Mexican  regulatory  bodies  may  impose  new  or  revised  requirements  that  could 
increase our operating costs and/or capital expenditures for operations in Mexican offshore waters. 

Under the PSCs, we are jointly and severally liable, along with Sierra and Premier, for the performance of all 
obligations  under  the  PSCs,  including  exploration,  appraisal,  extraction,  and  abandonment  activities  and 
compliance with all environmental regulations, and failure to perform such obligations could result in contractual 
recession of the PSCs.

Federal Regulation of Sales and Transportation of Natural Gas 

Our sales of natural gas are affected directly or indirectly by the availability, terms and cost of natural gas 
transportation.  The  prices  and  terms  for  access  to  pipeline  transportation  of  natural  gas  are  subject  to  extensive 
federal and state regulation. The transportation and sale for resale of natural gas in interstate commerce is regulated 
primarily under the Natural Gas Act of 1938 (“NGA”) and the Natural Gas Policy Act of 1978 (“NGPA”) and by 
regulations and orders promulgated under the NGA and/or NGPA by the Federal Energy Regulatory Commission 
(“FERC”). In certain limited circumstances, intrastate transportation and wholesale sales of natural gas may also be 
affected directly or indirectly by laws enacted by the United States Congress and by FERC regulations. However, 
certain offshore gathering and transportation services we rely upon are subject to limited FERC regulation and are 
regulated by the states. 

Pursuant  to  authority  delegated  to  it  by  the  Energy  Policy  Act  of  2005  (“EPAct  2005”),  the  FERC 
promulgated  anti-manipulation  regulations  establishing  violation  enforcement  mechanisms  that  make  it  unlawful 
for any entity, directly or indirectly, in connection with the purchase or sale of natural gas or the purchase or sale of 
transportation  services  subject  to  the  jurisdiction  of  FERC  to  (i) use  or  employ  any  device,  scheme  or  artifice  to 
defraud, (ii) make any untrue statement of a material fact or to omit to state a material fact necessary in order to 
make  the  statements  made,  in  the  light  of  the  circumstances  under  which  they  were  made,  not  misleading,  or 
(iii) engage in any act, practice or course of business that operates or would operate as a fraud or deceit upon any 
entity. The EPAct 2005 also amended the NGA and the NGPA to give FERC authority to impose civil penalties for 
violations  of  these  statutes  and  regulations,  up  to  $1,269,500  per  violation,  per  day  for  2019  (this  amount  is 
adjusted annually for inflation). The FERC may also order disgorgement of profits and corrective action. The anti-
market manipulation rule does not apply to activities that relate only to intrastate or other non-jurisdictional sales or 
gathering,  but  does  apply  to  activities  of  natural  gas  pipelines  and  storage  companies  that  provide  interstate 
services,  as  well  as  otherwise  non-jurisdictional  entities  to  the  extent  the  activities  are  conducted  “in  connection 
with” natural gas sales, purchases or transportation subject to FERC jurisdiction, which includes annual reporting 

28

6696_10K.pdf

requirements for entities that purchase or sell a certain volume of natural gas in a given calendar year. We believe, 
however, that neither the EPAct 2005 nor the regulations promulgated by FERC as a result of the EPAct 2005 will 
affect  us  in  a  way  that  materially  differs  from  the  way  they  affect  other  natural  gas  producers,  gatherers  and 
marketers with which we compete. 

Our  sales  of  oil  and  natural  gas  are  also  subject  to  market  manipulation  and  anti-disruptive  requirements 
under the Commodity Exchange Act (“CEA”) as amended by the Dodd-Frank Wall Street Reform and Consumer 
Protection Act (the “Dodd-Frank Act”), and regulations promulgated thereunder by the U.S. Commodity Futures 
Trading  Commission  (the  “CFTC”).  The  CFTC  prohibits  any  person  from  manipulating  or  attempting  to 
manipulate  the  price  of  any  commodity  in  interstate  commerce  or  futures  on  such  commodity.  The  CEA  also 
prohibits  knowingly  delivering  or  causing  to  be  delivered  false  or  misleading  or  knowingly  inaccurate  reports 
concerning market information or conditions that affect or tend to affect the price of a commodity. 

The  current  statutory  and  regulatory  framework  governing  interstate  natural  gas  transactions  is  subject  to 
change  in  the  future,  and  the  nature  of  such  changes  is  impossible  to  predict.  We  cannot  predict  whether  new 
legislation  to  regulate  natural  gas  might  be  proposed,  what  proposals,  if  any,  might  actually  be  enacted  by  the 
United States Congress, the applicable federal agencies, or the various state legislatures, and what effect, if any, the 
proposals might have on our operations. The natural gas industry historically has been very heavily regulated. In 
the past, the federal government regulated the prices at which natural gas could be sold. Since 1978, various federal 
laws have been enacted that have resulted in the complete removal of all price and non-price controls for sales of 
domestic natural gas sold in “first sales,” which include all of our sales of our own production. However, we are 
subject to reporting requirements imposed by FERC. There is always some risk, however, that the United States 
Congress  may  reenact  price  controls  in  the  future.  Changes  in  law  and  to  FERC  policies  and  regulations  may 
adversely  affect  the  availability  and  reliability  of  firm  and/or  interruptible  transportation  service  on  interstate 
pipelines  or  impose  additional  reporting  or  other  requirements  upon  our  operations,  and  we  cannot  predict  what 
future  action  the  FERC  will  take.  Therefore,  there  is  no  assurance  that  the  current  regulatory  approach  recently 
pursued  by  the  FERC  and  the  United  States  Congress  will  continue.  We  do  not  believe,  however,  that  any 
regulatory  changes  will  affect  us  in  a  way  that  materially  differs  from  the  way  they  will  affect  other  natural  gas 
producers, gatherers and marketers with which we compete. 

Federal Regulation of Sales and Transportation of Crude Oil 

The FERC regulates the interstate pipeline of crude oil, petroleum products, and other liquids, such as NGLs. 
Our sales of crude oil and condensate are currently not regulated and are made at negotiated prices. There is always 
some  risk,  however,  that  the  United  States  Congress  may  reenact  crude  oil,  petroleum  products  and  NGL  price 
controls  in  the  future.  We  cannot  predict  whether  new  legislation  to  regulate  crude  oil,  or  the  prices  charged  for 
crude oil might be proposed, what proposals, if any, might actually be enacted by the United States Congress or the 
various  state  legislatures  and  what  effect,  if  any,  the  proposals  might  have  on  our  operations.  Additionally,  such 
sales may be subject to certain state, and potentially federal, reporting requirements. 

Our ability to transport and sell such products is dependent on pipelines whose rates, terms and conditions of 
service  are  subject  to  FERC  jurisdiction  under  the  Interstate  Commerce  Act  (“ICA”),  and  intrastate  oil  pipeline 
transportation rates are subject to regulation by state regulatory commissions. Certain regulations implemented by 
the FERC in recent years and certain pending rulemaking and other proceedings could result in an increase in the 
cost  of  transportation  service  on  certain  petroleum  products  pipelines.  The  basis  for  intrastate  oil  pipeline 
regulation,  and  the  degree  of  regulatory  oversight  and  scrutiny  given  to  intrastate  oil  pipeline  rates,  varies  from 
state to state. We do not believe, however, that any regulatory changes will affect us in a way that materially differs 
from the way they will affect other crude oil and condensate producers with which we compete. 

Further, interstate and intrastate common carrier oil pipelines must provide service on a non-discriminatory 
basis. Under this open access standard, common carriers must offer service to all shippers requesting service on the 
same  terms  and  under  the  same  rates.  When  oil  pipelines  operate  at  full  capacity,  access  is  governed  by 
prorationing  provisions  set  forth  in  the  pipelines’  published  tariffs.  Accordingly,  we  believe  that  access  to  oil 
pipeline  transportation  services  generally  will  be  available  to  us  to  the  same  extent  as  to  other  crude  oil  and 
condensate producers with which we compete.

Our SP 49 Pipeline LLC system is subject to regulation by FERC under the ICA, the Energy Policy Act of 
1992,  and  the  rules  and  orders  promulgated  thereunder.    The  ICA  requires  that  tariff  rates  for  liquids  pipelines, 
which  include  both  crude  oil  pipelines  and  refined  products  pipelines,  be  just  and  reasonable  and  non-
discriminatory.  FERC-regulated liquids pipelines, including SP 49 Pipeline LLC, typically use the FERC indexing 
methodology to change its rates. The FERC, however, retained cost-of-service ratemaking, market-based rates and 
settlement rates as alternatives to the indexing approach that may be used in certain specified circumstances.  The 
FERC reviews the index formula every five years. Effective July 1, 2016, the annual index adjustment for the five-
year  period  ending  June  30,  2021,  will  equal  the  producer  price  index  for  finished  goods  for  the  applicable  year 
plus an adjustment factor of 1.23%. Pipelines may raise their rates to the rate ceiling level generated by application 
of the annual index adjustment factor each year; however, a shipper may challenge such increase if the increase in 
the  pipeline’s  rates  was  substantially  in  excess  of  the  actual  cost  increases  incurred  by  the  pipeline  during  the 
relevant year. Because the indexing methodology for the next five-year period is tied to an inflation index and is 
not based on pipeline-specific costs, the indexing methodology could hamper our ability to recover cost increases.  
On  March  15,  2018,  FERC  issued  a  Revised  Policy  Statement  on  Treatment  of  Income  Taxes  (“Revised  Policy 
Statement”)  stating,  among  other  things,  that  with  respect  to  oil  and  refined  products  pipelines  subject  to  FERC 
jurisdiction, the impacts of the Revised Policy Statement and the Tax Cuts and Jobs Act of 2017 on the costs of 
FERC-regulated oil and NGL pipelines will be reflected in FERC’s next five-year review of the oil pipeline index, 
which will generate the index level to be effective July 1, 2021. FERC’s establishment of a just and reasonable rate, 
including  the  determination  of  the  appropriate  oil  pipeline  index,  is  based  on  many  components,  and  tax-related 
changes will affect two such components, the allowance for income taxes and the amount for accumulated deferred 
income  taxes,  while  other  pipeline  costs  also  will  continue  to  affect  FERC’s  determination  of  the  appropriate 
pipeline index. Accordingly, depending on FERC’s application of its indexing rate methodology for the next five-
year term of index rates, the Revised Policy Statement and tax effects related to the Tax Cuts and Jobs Act of 2017 
may impact our revenues associated with any transportation services we may provide pursuant to cost-of-service 
based rates in the future, including indexed rates.

FERC historically has not investigated rates of liquids pipelines on its own initiative when those rates have 
not  been  the  subject  of  a  protest  or  complaint  by  a  shipper.  FERC  issued  an  Advance  Notice  of  Proposed 
Rulemaking  on  October  20,  2016,  that  addressed  issues  related  to  FERC’s  indexing  methodology  and  liquids 
pipeline  reporting  practices.  If  implemented,  the  proposals  in  this  rulemaking  could  affect  the  profitability  of 
certain liquids pipelines. 

We  have  an  undivided  interest  in  a  pipeline  owned  by  CKB  Petroleum,  Inc.  that  is  subject  to  FERC 
jurisdiction under the ICA, but FERC has granted us a temporary waiver of the filing and reporting requirements. 
This pipeline is still subject to FERC’s jurisdiction under the ICA and is still subject to the other requirements of 
the ICA. If the facts upon which the waiver was granted change materially, we are required to inform the FERC, 
which may result in revocation of the waiver.  If conditions change such that the pipeline no longer qualifies for a 
waiver,  we  may  be  subject  to  regulation  by  FERC  of  the  rates,  terms,  and  conditions  of  service  on  the  CKB 
Petroleum, Inc. pipeline, however these burdens generally would not affect us any differently or to any greater or 
lesser extent than they affect others in our industry with similar pipelines. 

The FERC also implements the OCSLA pertaining to transportation and pipeline issues, which requires that 
all pipelines operating on or across the OCS provide nondiscriminatory transportation service. We own and operate 
pipelines that are located in the OCS and are subject to the non-discrimination requirements in the OCSLA. 

Employees 

We had 374 employees as of March 6, 2019.

Item 1A. Risk Factors

Certain  factors  may  have  a  material  adverse  effect  on  our  business,  financial  condition,  and  results  of 
operations.  You  should  consider  carefully  the  risks  and  uncertainties  described  below,  in  addition  to  other 
information contained in this Annual Report on Form 10-K, including our consolidated financial statements and 
related  notes.  The  risks  and  uncertainties  described  below  are  not  the  only  ones  we  face.  Additional  risks  and 
uncertainties  that  we  are  unaware  of,  or  that  we  currently  believe  are  not  material,  may  also  become  important 
factors  that  adversely  affect  our  business.  If  any  of  the  following  risks  actually  occur,  our  business,  financial 
condition, results of operations and future prospects could be materially and adversely affected. In that event, the 
trading price of our common stock could decline, and you could lose part or all of your investment.

Oil  and  natural  gas  prices  are  volatile.  Significant  declines  in  commodity  prices  in  the  future  may  adversely 
affect our financial condition and results of operations, cash flows, access to the capital markets, and ability to 
grow. 

Our revenues, cash flows, profitability, and future rate of growth substantially depend upon the market prices 
of oil and natural gas. Prices affect our cash flows available for capital expenditures and our ability to access funds 
under  our  Bank  Credit  Facility  and  through  the  capital  markets.  The  amount  available  for  borrowing  under  our 
Bank  Credit  Facility  is  subject  to  a  borrowing  base,  which  is  determined  by  the  lenders  taking  into  account  our 
estimated proved reserves, and is subject to periodic redeterminations based on pricing models to be determined by 
the lenders at such time. Oil and natural gas prices significantly declined in the second half of 2014, with sustained 
lower prices continuing throughout 2015, 2016 and 2017. Despite a modest recovery from late 2017 to mid-2018, 
commodity prices could remain suppressed or decline further in the future, which will likely have material adverse 
effects on our proved reserves and borrowing base. Further, because we use the full cost method of accounting for 
our  oil  and  gas  operations,  we  perform  a  ceiling  test  each  quarter,  which  is  impacted  by  declining  prices. 
Significant  price  declines  could  cause  us  to  take  ceiling  test  write-downs,  which  would  be  reflected  as  non-cash 
charges against current earnings. See the Risk Factor entitled “Lower oil and natural gas prices and other factors in 
the  future  may  result  in  ceiling  test  write-downs  and  other  impairments  of  our  asset  carrying  values”  for  further 
discussion. 

In addition, significant or extended price declines may also adversely affect the amount of oil and natural gas 
that we can produce economically. A reduction in production could result in a shortfall in our expected cash flows 
and  require  us  to  reduce  our  capital  spending  or  borrow  funds  to  cover  any  such  shortfall.  Any  of  these  factors 
could negatively impact our ability to replace our production and our future rate of growth. 

The  markets  for  oil  and  natural  gas  have  been  volatile  historically  and  are  likely  to  remain  volatile  in  the 
future. For example, during the period January 1, 2016 through December 31, 2018, the NYMEX WTI crude oil 
price  per  Bbl  ranged  from  a  low  of  $30.62  to  a  high  of  $70.76,  and  the  NYMEX  natural  gas  price  per  MMBtu 
ranged from a low of $1.71 to a high of $4.72. The high, low and average prices for NYMEX WTI and NYMEX 
Henry Hub are monthly contract prices. The prices we receive for our oil and natural gas depend upon many factors 
beyond our control, including, among others: 

• changes in the supply of and demand for oil and natural gas; 

• market uncertainty; 

•

level of consumer product demands; 

• hurricanes and other adverse weather conditions; 

• domestic and foreign governmental regulations and taxes; 

• price and availability of alternative fuels; 

• political and economic conditions in oil-producing countries, particularly those in the Middle East, Russia, 

South America and Africa; 

• actions  by  the  Organization  of  Petroleum  Exporting  Countries  and  other  state-controlled  oil  companies 

relating to oil and natural gas price and production controls; 

• U.S. and foreign supply of oil and natural gas; 

• price and quantity of oil and natural gas imports and exports; 

31

6696_10K.pdf

•

•

•

the level of global oil and natural gas exploration and production; 

the level of global oil and natural gas inventories; 

localized supply and demand fundamentals and transportation availability; 

• speculation as to the future price of oil and the speculative trading of oil and natural gas futures contracts; 

• price and availability of competitors’ supplies of oil and natural gas; 

•

technological advances affecting energy consumption; and 

• overall domestic and foreign economic conditions. 

These  factors  make  it  very  difficult  to  predict  future  commodity  price  movements  with  any  certainty. 
Substantially all of our oil and natural gas sales are made in the spot market or pursuant to contracts based on spot 
market  prices  and  are  not  long-term  fixed  price  contracts.  Further,  oil  prices  and  natural  gas  prices  do  not 
necessarily  fluctuate  in  direct  relation  to  each  other.  Because  oil,  natural  gas,  and  NGLs  accounted  for 
approximately  74%,  19%,  and  7%,  respectively,  of  our  estimated  proved  reserves  as  of  December 31,  2018,  and 
approximately 70%, 23%, and 7%, respectively, of our 2018 production on an MBoe basis, our financial results are 
sensitive to movements in oil, natural gas, and NGL prices. 

We  are  required  to  meet  a  minimum  work  program  expressed  in  work  units  during  a  four-year  exploration 
period according to our PSCs with the CNH. 

On September 11, 2018, we entered into a transaction with Hokchi, a subsidiary of PAE, to cross assign 25% 
PIs in Block 2 and Block 31, both in the Sureste Basin off the coast of Mexico. Our assignment of a 25% PI in 
Block 2 to Hokchi closed on December 21, 2018, and Hokchi has assumed operator responsibilities with respect to 
Block 2. Hokchi’s assignment of Block 31 to us will be completed upon final approval by the CNH. In addition, 
Premier exercised its option to reduce its PI in Block 2 to zero and assign a 5% PI to each of Sierra and us. Such 
assignment is also subject to CNH’s approval. Upon the completion of the Hokchi Cross Assignment and Premier’s 
option exercise, Hockchi will be the operator of both blocks, we will own a 25% PI in Block 31 and our PI in Block 
2, and our pro rata portion of the minimum work program on Block 2 will decrease from 45% to 25%. We posted  
an additional $8.7 million required in letters of credit to cover our pro rata portion of the minimum work program 
on Block 31 pursuant to the relevant PSC.

If we or the Consortium is unable to meet a minimum work program, we could be liable along with the other 
members  in  the  Consortium  for  the  remaining  financial  guarantee,  and  the  CNH  could  rescind  the  PSC  for  a 
default.

Our debt level and the covenants in our current or future agreements governing our debt, including our Bank 
Credit Facility and the indenture for our 11.00% Senior Secured Notes, could negatively impact our financial 
condition, results of operations, and business prospects. Our failure to comply with these covenants could result 
in the acceleration of our outstanding indebtedness. 

The  terms  of  the  agreements  governing  our  debt  impose  significant  restrictions  on  our  ability  to  take  a 

number of actions that we may otherwise desire to take, including:

•

incurring additional debt; 

• paying dividends on stock, redeeming stock, or redeeming subordinated debt; 

• making investments; 

• creating liens on our assets; 

• selling assets; 

• guaranteeing other indebtedness; 

• entering into agreements that restrict dividends from our subsidiaries to us; 

• merging, consolidating, or transferring all or substantially all of our assets; 

32

6696_10K.pdf

• hedging future production; and 

• entering into transactions with affiliates. 

Our level of indebtedness, and the covenants contained in the agreements governing our debt, including the 
Bank Credit Facility and the indenture for our 11.00% Senior Secured Notes, have important consequences on our 
operations, including: 

•

•

•

requiring  that  we  dedicate  a  substantial  portion  of  our  cash  flow  from  operating  activities  to  required 
payments on debt, thereby reducing the availability of cash flow for working capital, capital expenditures, 
and other general business activities; 

limiting  our  ability  to  obtain  additional  financing  in  the  future  for  working  capital,  capital  expenditures, 
acquisitions, and other general business activities; 

limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we 
operate; 

• detracting from our ability to successfully withstand a downturn in our business or the economy generally; 

• placing us at a competitive disadvantage against other less leveraged competitors; and 

• making  us  vulnerable  to  increases  in  interest  rates  because  debt  under  our  Bank  Credit  Facility  is  at 

variable rates. 

We may be required to repay all or a portion of our debt on an accelerated basis in certain circumstances. If 
we fail to comply with the covenants and other restrictions in the agreements governing our debt, it could lead to an 
event of default and the acceleration of repayment of outstanding debt. Our ability to comply with these covenants 
and other restrictions may be affected by events beyond our control, including prevailing economic and financial 
conditions.  Sustained  low  oil  and  natural  gas  prices  have  a  material  and  adverse  effect  on  our  liquidity  position. 
Our  cash  flow  is  highly  dependent  on  the  prices  we  receive  for  oil  and  natural  gas,  which  have  declined 
significantly as compared to mid-2014. 

We depend on our Bank Credit Facility for a portion of our future capital needs. We are required to comply 
with certain debt covenants and certain financial ratios under the Bank Credit Facility. Our borrowing base under 
the Bank Credit Facility, which is redetermined semi-annually, is based on an amount established by the lenders 
after their evaluation of our proved oil and natural gas reserve values. If, due to a redetermination of our borrowing 
base,  our  outstanding  borrowings  plus  outstanding  letters  of  credit  exceed  our  redetermined  borrowing  base 
(referred to as a borrowing base deficiency), we could be required to repay such borrowing base deficiency. Our 
Bank  Credit  Facility  allows  us  to  cure  a  borrowing  base  deficiency  through  any  combination  of  the  following 
actions:  (i) repay  amounts  outstanding  sufficient  to  cure  the  borrowing  base  deficiency  within  30  days  after  the 
existence of such deficiency; (ii) add additional oil and gas properties acceptable to the banks to the borrowing base 
and take such actions necessary to grant the banks a mortgage in such oil and gas properties within 30 days after 
the  existence  of  such  deficiency;  (iii) pay  the  deficiency  in  four  equal  monthly  installments  with  the  first 
installment due within 30 days after the existence of such deficiency; or (iv) any combination of the above. We are 
required to elect one of the foregoing options within 10 days after the existence of such deficiency. 

We may not have sufficient funds to make such repayments. If we do not repay our debt out of cash on hand, 
we could attempt to restructure or refinance such debt, reduce or delay investments and capital expenditures, sell 
assets, or repay such debt with the proceeds from an equity offering. We cannot assure you that we will be able to 
generate sufficient cash flows from operating activities to pay the interest on our debt or that future borrowings, 
equity financings, or proceeds from the sale of assets are available to pay or refinance such debt. Any refinancing 
of indebtedness could be at higher interest rates and may require us to comply with more onerous covenants, which 
could  further  restrict  business  operations.  The  terms  of  our  debt,  including  our  Bank  Credit  Facility  and  the 
indenture for our 11.00% Senior Secured Notes, may also prohibit us from taking such actions. Factors that affect 
our ability to raise cash through offerings of our capital stock, a refinancing of our debt, or a sale of assets include 
financial  market  conditions  and  our  market  value  and  operating  performance  at  the  time  of  such  offerings, 
refinancing, or sale of assets. We cannot assure you that any such offerings, restructuring, refinancing, or sale of 
assets would be successfully completed.

Regulatory  requirements  and  permitting  procedures  imposed  by  the  BOEM  and  the  BSEE  could  significantly 
delay our ability to obtain permits to drill new wells in offshore waters. 

BSEE  and  BOEM  have  imposed  new  and  more  stringent  permitting  procedures  and  regulatory  safety  and 
performance  requirements  for  new  wells  to  be  drilled  in  federal  waters.  Compliance  with  these  added  and  more 
stringent regulatory requirements and with existing environmental and spill regulations, together with uncertainties 
or inconsistencies in decisions and rulings by governmental agencies and delays in the processing and approval of 
drilling  permits  and  exploration,  development,  oil  spill  response,  and  decommissioning  plans  and  possible 
additional regulatory initiatives could result in difficult and more costly actions and adversely affect or delay new 
drilling  and  ongoing  development  efforts.  Moreover,  these  governmental  agencies  are  continuing  to  evaluate 
aspects of safety and operational performance in the Gulf of Mexico and, as a result, are continuing to develop and 
implement  new,  more  restrictive  requirements.  For  example,  in  April  2016,  BSEE  published  a  final  rule  on  well 
control that, among other things, imposes rigorous standards relating to the design, operation, and maintenance of 
blow-out  preventers,  real-time  monitoring  of  deepwater,  high  temperature,  high  pressure  drilling  activities,  and 
enhanced  reporting  requirements.  Pursuant  to  the  Executive  Orders,  BSEE  initiated  a  review  of  the  well  control 
regulations to determine whether the rules are consistent with the stated policy of encouraging energy exploration 
and production, while ensuring that any such activity is safe and environmentally responsible. One consequence of 
this review is that in September 2018, BSEE published final revisions to its regulations regarding offshore drilling 
safety  equipment,  which  includes  the  removal  of  the  requirement  for  offshore  operators  to  certify  through  an 
independent third party that their critical safety and pollution prevention equipment (e.g., subsea safety equipment, 
including blowout preventers) is operational and functioning as designed in the most extreme conditions. 

Also, in April 2016, BOEM published a proposed rule that would update existing air emissions requirements 
relating to offshore oil and natural gas activity on the OCS. BOEM regulates these air emissions in connection with 
its review of exploration and development plans, rights of way and rights of use, and/or easement applications. The 
proposed rule would bolster existing air emissions requirements by, among other things, requiring the reporting and 
tracking of the emissions of all pollutants defined by the EPA to affect human health and public welfare. Pursuant 
to the Executive Orders, BOEM has ceased rulemaking activities for and is reviewing the proposed air quality rule. 
In October 2017, the DOI announced that it is currently reviewing recommendations on how to proceed, including 
promulgating  final  rules  for  certain  necessary  provisions  and  issuing  a  new  proposed  rule  that  may  withdraw 
certain provisions and seek additional input on others. 

Compliance  with  new  and  future  regulations  could  result  in  significant  costs,  including  increased  capital 
expenditures  and  operating  costs,  and  could  adversely  impact  our  business.  Furthermore,  among  other  adverse 
impacts,  to  the  extent  that  BOEM  and  BSEE  do  not  reduce  the  stringency  of  existing  oil  and  gas  safety  and 
performance-related  regulations  and  other  regulatory  initiatives,  the  regulatory  requirements  imposed  by  such 
existing  or  future,  more  stringent  regulations  or  other  regulatory  initiatives  could  delay  operations,  disrupt  our 
operations, or increase the risk of leases expiring before exploration and development efforts have been completed 
due to the time required to develop new technology. Additionally, if left unchanged, the existing, or future, more 
stringent oil and gas safety and performance-related regulations and other regulatory initiatives imposed by BOEM 
and BSEE could result in incurrence of associated added costs, limit operational activities in certain areas, or cause 
us to incur penalties or shut-in production at one or more of our facilities. Also, if material spill incidents were to 
occur  in  the  future,  the  United  States  or  other  countries  where  such  an  event  may  occur  could  elect  to  issue 
directives to temporarily cease drilling activities and, in any event, may from time to time issue further safety and 
environmental  laws  and  regulations  regarding  offshore  oil  and  natural  gas  exploration  and  development,  any  of 
which could have a material adverse effect on our business. We cannot predict with any certainty the full impact of 
any new laws or regulations on our drilling operations or on the cost or availability of insurance to cover some or 
all of the risks associated with such operations. 

New  guidelines  issued  by  BOEM  related  to  financial  assurance  requirements  to  cover  decommissioning 
obligations for operations on the OCS may have a material adverse effect on our business, financial condition, 
or results of operations. 

BOEM  requires  that  lessees  demonstrate  financial  strength  and  reliability  according  to  its  regulations  or 
provide  acceptable  financial  assurances  to  assure  satisfaction  of  lease  obligations,  including  decommissioning 
activities  on  the  OCS.    In  July  2016,  BOEM  issued  the  2016  NTL  to  clarify  the  procedures  and  guidelines  that 
BOEM Regional Directors use to determine if and when additional financial assurances may be required for OCS 
leases,  ROWs  or  RUEs.    The  2016  NTL  became  effective  in  September  2016,  but  BOEM  has  since  extended 
indefinitely beyond June 30, 2017 the start date for implementing this NTL, except in certain circumstances where 
there is a substantial risk of nonperformance of the interest holder’s decommissioning liabilities, so as to provide 
BOEM with time to review its complex financial assurance program.

6696_10K.pdf

In late 2016, we received orders from BOEM to provide additional financial assurance in material amounts 
relating to our OCS properties (the “BOEM 2016 Orders”). We entered into discussions with BOEM regarding the 
requested additional financial security and submitted a proposed tailored plan for the posting of additional financial 
security  to  the  agency  for  review.  However,  as  noted,  BOEM  has  indefinitely  delayed  beyond  June  30,  2017 
implementation  of  the  2016  NTL,  has  rescinded  the  BOEM  2016  Orders  while  BOEM  reviews  its  financial 
assurance  program  and,  to  date,  has  taken  no  action  with  respect  to  our  previously  submitted  proposed  tailored 
plan.

As  of  the  filing  date  of  this  Annual  Report  on  Form  10-K,  we  have  no  outstanding  BOEM  orders  for 
financial  assurance  obligations,  although  we  are  in  discussions  with  the  agency  regarding  providing  financial 
assurance in what we view as the normal course of business for one well, Mount Providence, that was completed 
July 2018.  Following completion of its review of its financial assurance program, BOEM may elect to retain the 
2016  NTL  in  its  current  form  or  may  make  revisions  thereto.  Thus,  until  the  review  is  completed  and  BOEM 
determines  what  additional  financial  assurance  may  be  required  by  us,  we  cannot  provide  any  assurance  of  the 
amount of any additional financial assurance, which may be material, that may be ordered by BOEM and required 
in  any  proposed  tailored  plan  that  we  may  submit  to  BOEM  in  the  future  for  approval,  or  that  such  additional 
financial  assurance  amounts  can  be  obtained.    Moreover,  BOEM  could  in  the  future  make  new  demands  for 
additional financial assurances in material amounts relating to the decommissioning of our OCS properties. BOEM 
may reject our proposals to satisfy any such additional financial assurance coverage and make demands that exceed 
our capabilities.

If we fail to comply with the current or future orders of BOEM to provide additional surety bonds or other 
financial  assurances,  BOEM  could  commence  enforcement  proceedings  or  take  other  remedial  action,  including 
assessing civil penalties, suspending operations or production, or initiating procedures to cancel leases, which, if 
upheld,  would  have  a  material  adverse  effect  on  our  business,  properties,  results  of  operations  and  financial 
condition.

In  addition,  if  fully  implemented,  the  2016  NTL  is  likely  to  result  in  the  loss  of  supplemental  bonding 
waivers for a large number of operators on the OCS, which could in turn force these operators to seek additional 
surety bonds and could, consequently, challenge the surety bond market’s capacity for providing such additional 
financial assurance. Operators who have already leveraged their assets as a result of the declining oil market could 
face  difficulty  obtaining  surety  bonds  because  of  concerns  the  surety  companies  may  have  about  the  priority  of 
their  lien  on  the  operator’s  collateral.  Moreover,  depressed  oil  prices  could  result  in  sureties  seeking  additional 
collateral to support existing bonds, such as cash or letters of credit, and we cannot provide assurance that we will 
be  able  to  satisfy  collateral  demands  for  future  bonds  to  comply  with  supplemental  bonding  requirements  of 
BOEM. If we are required to provide collateral in the form of cash or letters of credit, our liquidity position could 
be negatively impacted and we may be required to seek alternative financing. To the extent we are unable to secure 
adequate financing, we may be forced to reduce our capital expenditures. All of these factors may make it more 
difficult for us to obtain the financial assurances required by BOEM to conduct operations on the OCS. These and 
other  changes  to  BOEM  bonding  and  financial  assurance  requirements  could  result  in  increased  costs  on  our 
operations and consequently have a material adverse effect on our business and results of operations. 

We have a subsidiary that is subject to a plea agreement with the Department of Justice (“DOJ”) pursuant to 
which certain exploration and production activities must comply with a Safety and Environmental Compliance 
Program  (“SECP”).  Noncompliance  with  the  SECP  could  result  in  a  violation  of  the  plea  agreement  and 
provide a basis for revocation or modification of probation. 

In February 2014, we received a grand jury subpoena from the DOJ addressing activities that occurred on the 
Ship Shoal 225A production platform operated by one of our subsidiaries, ERT. On November 30, 2015, ERT was 
charged with two violations of the OCSLA in connection with hot work and blowout preventer testing activities, 
and  with  two  violations  of  the  CWA  for  self-reported  activities  surrounding  overboard  discharge  sampling  and 
unpermitted discharges. On January 6, 2016, ERT pled guilty to these charges. On April 6, 2016, the United States 
District  Court  for  the  Eastern  District  of  Louisiana  (the  “Court”)  accepted  ERT’s  plea  and  sentenced  ERT, 
consistent with the plea agreement, to pay a penalty of $4.2 million, which ERT has paid. The Court placed ERT 
on  probation  for  three  years. The  conditions  of  probation  include  compliance  with  an  agreed  SECP,  pursuant  to 
which  ERT  and  another  subsidiary  of  ours  must  implement  enhanced  safety  and  environmental  compliance 
inspections,  reviews  and  audits,  implement  a  comprehensive  training  program,  implement  enhanced  operational 
controls  to  better  manage,  detect  and  prevent  safety  and  environmental  violations,  and  preparation  and 
implementation  of  a  schedule  for  decommissioning.  Any  failure  to  comply  with  the  SECP  could  result  in  a 
violation  of  the  plea  agreement  and  provide  a  basis  for  revocation  or  modification  of  probation,  which  could 
adversely our financial condition and operations.

A  financial  crisis  may  impact  our  business  and  financial  condition  and  may  adversely  impact  our  ability  to 
obtain funding under our Bank Credit Facility or in the capital markets. 

We use our cash flows from operating activities and borrowings under our Bank Credit Facility to fund our 
capital  expenditures,  and  we  rely  on  the  capital  markets  and  asset  monetization  transactions  to  provide  us  with 
additional capital for large or exceptional transactions. However, we may not be able to access adequate funding 
under our Bank Credit Facility as a result of (i) a decrease in our borrowing base due to the outcome of a borrowing 
base  redetermination  or  a  breach  or  default  under  our  Bank  Credit  Facility,  including  a  breach  of  a  financial 
covenant  or  (ii) an  unwillingness  or  inability  on  the  part  of  our  lending  counterparties  to  meet  their  funding 
obligations. In addition, we may face limitations on our ability to access the debt and equity capital markets and 
complete asset sales, an increased counterparty credit risk on our derivatives contracts, and the requirement by our 
contractual counterparties to post collateral guaranteeing performance. 

We require substantial capital expenditures to conduct our operations and replace our production, and we may 
be unable to obtain needed financing on satisfactory terms necessary to fund our planned capital expenditures. 

We  spend  a  substantial  amount  of  capital  for  the  acquisition,  exploration,  exploitation,  development,  and 
production  of  oil  and  natural  gas  reserves.  We  fund  our  capital  expenditures  primarily  through  operating  cash 
flows, cash on hand and borrowings under our Bank Credit Facility, if necessary. The actual amount and timing of 
our future capital expenditures may differ materially from our estimates as a result of, among other things, oil and 
natural  gas  prices,  actual  drilling  results,  the  availability  of  drilling  rigs  and  other  services  and  equipment,  and 
regulatory, technological and competitive developments. A further reduction in commodity prices may result in a 
further decrease in our actual capital expenditures, which would negatively impact our ability to grow production. 

Our cash flow from operations and access to capital is subject to a number of variables, including: 

• our proved reserves; 

•

•

the level of hydrocarbons we are able to produce from our wells; 

the prices at which our production is sold; 

• our ability to acquire, locate, and produce new reserves; and 

• our ability to borrow under our Bank Credit Facility. 

If low oil and natural gas prices, operating difficulties, declines in reserves or other factors, many of which 
are beyond our control, cause our revenues, cash flows from operating activities, and the borrowing base under our 
Bank  Credit  Facility  to  decrease,  we  may  be  limited  in  our  ability  to  fund  the  capital  necessary  to  complete  our 
capital expenditure program. After utilizing our available sources of financing, we may be forced to raise additional 
debt  or  equity  proceeds  to  fund  such  capital  expenditures.  We  cannot  be  sure  that  additional  debt  or  equity 
financing will be available, and we cannot be sure that cash flows provided by operations will be sufficient to meet 
these  requirements.  For  example,  the  ability  of  oil  and  gas  companies  to  access  the  equity  and  high  yield  debt 
markets has been significantly limited since the significant decline in commodity prices as compared to mid-2014. 
Access to the equity and high yield debt markets continue to be limited.

We are a holding company that has no material assets other than our ownership of the equity interests of Talos 
Production.  Accordingly,  we  are  dependent  upon  distributions  from  Talos  Production  to  pay  taxes,  cover  our 
corporate and other overhead expenses and pay dividends, if any, on our common stock.

We  are  a  holding  company  that  has  no  material  assets  other  than  our  ownership  of  the  equity  interests  of 
Talos  Production.  We  have  no  independent  means  of  generating  revenue.  To  the  extent  Talos  Production  has 
available cash, we will cause Talos Production to make distributions of cash to us, directly and indirectly through 
our wholly owned subsidiaries, to pay taxes, cover our corporate and other overhead expenses and pay dividends, if 
any,  on  our  common  stock.  As  we  have  never  declared  or  paid  any  cash  dividends  on  our  common  stock,  we 
anticipate  that  any  available  cash,  other  than  the  cash  distributed  to  us  to  pay  taxes  and  cover  our  corporate  and 
other  overhead  expenses,  will  be  retained  by  Talos  Production  to  satisfy  its  operational  and  other  cash  needs. 
Accordingly,  we  do  not  anticipate  paying  any  cash  dividends  on  our  common  stock  in  the  foreseeable  future. 
Although we do not expect to pay dividends on our common stock, if our board of directors decides to do so in the 
future,  our  ability  to  do  so  may  be  limited  to  the  extent  Talos  Production  is  limited  in  its  ability  to  make 
distributions to us, including the significant restrictions the agreements governing Talos Production’s debt impose 
on the ability of Talos Production to make distributions and other payments to us. To the extent that we need funds 
and Talos Production is restricted from making such distributions under applicable law or regulation or under the 
terms of our financing agreements, or is otherwise unable to provide such funds, it could materially adversely affect 
our liquidity and financial condition.

Our production, revenue and cash flow from operating activities are derived from assets that are concentrated in 
a single geographic area, making us vulnerable to risks associated with operating in one geographic area. 

Our  production,  revenue,  and  cash  flow  from  operating  activities  are  derived  from  assets  that  are 
concentrated in a single geographic area, the Gulf of Mexico and in the shallow waters off the coast of Mexico. 
Unlike other entities that are geographically diversified, we may not have the resources to effectively diversify our 
operations or benefit from the possible spreading of risks or offsetting of losses. Our lack of diversification may 
subject  us  to  numerous  economic,  competitive  and  regulatory  developments,  any  or  all  of  which  may  have  an 
adverse  impact  upon  the  particular  industry  in  which  we  operate,  and  result  in  our  dependency  upon  a  single  or 
limited number of hydrocarbon basins. In addition, the geographic concentration of our properties in the Gulf of 
Mexico and in the shallow waters off the coast of Mexico means that some or all of our properties could be affected 
should the region experience: 

• severe weather, such as hurricanes and other adverse weather conditions; 

• delays or decreases in production, the availability of equipment, facilities or services; 

• delays or decreases in the availability or capacity to transport, gather or process production; 

• changes  in  the  status  of  pipelines  that  we  depend  on  for  transportation  of  our  production  to  the 

marketplace; 

• extensive governmental regulation (including regulations that may, in certain circumstances, impose strict 
liability for pollution damage or require posting substantial bonds to address decommissioning and P&A 
costs) and interruption or termination of operations by governmental authorities based on environmental, 
safety or other considerations; and/or 

• changes  in  the  regulatory  environment  such  as  the  guidelines  issued  by  BOEM  related  to  financial 

assurance requirements to cover decommissioning obligations for operations on the OCS. 

Because all or a number of our properties could experience many of the same conditions at the same time, 
these conditions may have a relatively greater impact on our results of operations than they might have on other 
producers who have properties over a wider geographic area. 

We may experience significant shut-ins and losses of production due to the effects of hurricanes in the Gulf of 
Mexico and in the shallow waters off the coast of Mexico. 

Our production is primarily associated with our properties in the Gulf of Mexico and in the shallow waters 
off  the  coast  of  Mexico.  Accordingly,  if  the  level  of  production  from  these  properties  substantially  declines,  it 
could  have  a  material  adverse  effect  on  our  overall  production  level  and  our  revenue.  We  are  particularly 
vulnerable to significant risk from hurricanes and tropical storms in the Gulf of Mexico. We are unable to predict 
what impact future hurricanes and tropical storms might have on our future results of operations and production. 

A significant portion of our production, revenue and cash flow is concentrated in our Phoenix Field and our 
Pompano  Field.  Because  of  this  concentration,  any  production  problems,  impacts  of  adverse  weather  or 
inaccuracies in reserve estimates could have a material adverse impact on our business. 

For the year ended December 31, 2018, approximately 39% and 15% of our historical production and 41% 
and 17% of our historical oil, natural gas, and NGL revenue was attributable to our Phoenix Field and our Pompano 
Field,  respectively,  both  of  which  are  located  in  the  federal  waters  offshore  in  the  Gulf  of  Mexico.  This 
concentration  in  these  fields  means  that  any  impact  on  our  production  from  these  fields,  whether  because  of 
mechanical  problems,  adverse  weather,  well  containment  activities,  changes  in  the  regulatory  environment,  or 
otherwise,  could  have  a  material  effect  on  our  business.  We  produce  the  Phoenix  Field  through  the  HP-I,  a 
dynamically positioned floating production facility that is operated by Helix. The HP-I interconnects the Phoenix 
Field through a production buoy that can be disconnected if the HP-I cannot maintain its position on station, such 
as  in  the  event  of  a  mechanical  problem  with  the  dynamic  positioning  system  or  the  approach  of  a  hurricane. 
Because  the  HP-I  may  have  to  be  disconnected  from  the  Phoenix  Field  if  circumstances  require,  our  production 
from the Phoenix Field may be subject to more frequent interruptions than if the Phoenix Field was produced by a 
more conventional platform. We are also required to disconnect and dry-dock the HP-I every two to three years for 
inspection as required by the United States Coast Guard, during which time we are unable to produce the Phoenix 
Field. As of the filing date of this Annual Report on Form 10-K, Helix has dry-docked the HP-I, and the shut-in is 
estimated to through March 2019. On September 10, 2016, the HP-I was disconnected from the production buoy 

37

6696_10K.pdf

and released for dry dock for 28 days. Upon completion of the dry dock, the HP-I remained disconnected from the 
buoy connecting it to the Phoenix Field due to Federal Emergency Management Agency testing of test upgrades to 
the power management system, preventing us from reconnecting the HP-I to the Phoenix Field for a further five 
days.  Once  the  buoy  was  connected,  Phoenix  Field  production  remained  shut-in  for  an  additional  five  days  to 
conduct  buoy  remediation  of  the  swivel  piping.  In  addition,  for  25  days  in  March  2015,  we  were  required  to 
disconnect  the  HP-I  from  the  production  buoy  due  to  upgrades  to  the  power  management  system  of  the  vessel, 
which  is  an  integral  part  of  the  dynamic  positioning  system.  The  upgrade  work  was  followed  by  sea  trials  that 
tested the dynamic positioning system and were required by various regulatory groups, including the United States 
Coast Guard. 

The HP-I is part of the Helix Well Containment Group (“HWCG”), which is a consortium that is available to 
respond to any deepwater well control event, such as the Macondo well oil spill. If such an event were to occur and 
the HWCG was to be utilized for well control, the HP-I, which is the vessel that would be used to respond to the 
deepwater well control event, would be required to disconnect from the Phoenix Field until such time as the well 
control event was resolved and the HP-I could return to the Phoenix Field. During such time period, we would not 
be  able  to  produce  the  Phoenix  Field.  In  the  event  the  HP-I  has  to  disconnect  from  the  Phoenix  Field,  our 
production, revenue, and cash flow could be adversely affected, which could have a material adverse effect on our 
business, financial condition, results of operations and cash flows. 

In  addition,  all  of  our  production  from  the  Phoenix  Field  flows  through  the  Green  Canyon  19  connection 
facility  operated  by  Shell  GOM  Pipeline  Company  LLC.  To  the  extent  Shell  GOM  Pipeline  Company  LLC 
temporarily shuts in its Green Canyon 19 connection facility, whether for maintenance or otherwise, we would not 
able  to  produce  the  Phoenix  Field  during  this  period  of  time,  which  may  have  a  material  adverse  effect  on  our 
business, financial condition, results of operations and cash flows. 

If the actual reserves associated with the Phoenix Field are less than our estimated reserves, such a reduction 
of reserves could have a material adverse effect on our business, financial condition, results of operations and cash 
flows. 

In  addition,  all  of  our  production  from  the  Pompano  Field  flows  through  the  Pompano  Pipeline  System 
operated  by  Crimson  Gulf  LLC.  To  the  extent  Crimson  Gulf  LLC  temporarily  shuts  in  the  Pompano  Pipeline 
System,   whether for maintenance or otherwise, we would not be able to produce the Pompano Field during this 
period of time, which may have a material adverse effect on our business, financial condition, results of operations 
and cash flows.

If  the  actual  reserves  associated  with  the  Pompano  Field  are  less  than  our  estimated  reserves,  such  a 
reduction of reserves could have a material adverse effect on our business, financial condition, results of operations 
and cash flows.

We are not insured against all of the operating risks to which our business is exposed. 

In accordance with industry practice, we maintain insurance against some, but not all, of the operating risks 
to  which  our  business  is  exposed.  We  insure  some,  but  not  all,  of  our  properties  from  operational  loss-related 
events. We have insurance policies that include coverage for general liability, physical damage to our oil and gas 
properties,  operational  control  of  well,  named  Gulf  of  Mexico  windstorm,  oil  pollution,  construction  all  risk, 
workers’ compensation and employers’ liability and other coverage. Our insurance coverage includes deductibles 
that have to be met prior to recovery, as well as sub-limits or self-insurance. Additionally, our insurance is subject 
to  exclusions  and  limitations,  and  there  is  no  assurance  that  such  coverage  will  adequately  protect  us  against 
liability from all potential consequences, damages or losses. 

We have general liability insurance coverage with an annual aggregate limit of $500 million. We selectively 
purchase  physical  damage  insurance  coverage  for  our  pipelines,  platforms,  facilities  and  umbilicals  for  losses 
resulting from named windstorms and operational activities. 

Our operational control of well coverage is expected to provide limits that vary by well location and depth 
and range from a combined single limit of $25 million to $500 million per occurrence. Exploratory deepwater wells 
have  a  coverage  limit  of  up  to  $500 million  per  occurrence.  Additionally,  we  maintain  up  to  $150 million  in  oil 
pollution  liability  coverage.  Our  operational  control  of  well  and  physical  damage  policy  limits  is  scaled 
proportionately to our working interests. Our general liability program utilizes a combination of assured’s interest 
and  scalable  limits.  All  of  our  policies  described  above  are  subject  to  deductibles,  sub-limits,  or  self-insurance. 
Under our service agreements, including drilling contracts, generally we are indemnified for injuries and death of 
the service provider’s employees as well as contractors and subcontractors hired by the service provider, subject to 
the application of various states’ laws.

An operational or hurricane or other adverse weather-related event may cause damage or liability in excess of 
our  coverage  that  might  severely  impact  our  financial  position.  We  may  be  liable  for  damages  from  an  event 
relating to a project in which we own a non-operating working interest. Such events may also cause a significant 
interruption  to  our  business,  which  might  also  severely  impact  our  financial  position.  We  may  experience 
production interruptions for which we do not have production interruption insurance. 

We reevaluate the purchase of insurance, policy limits and terms annually. Future insurance coverage for our 
industry  could  increase  in  cost  and  may  include  higher  deductibles  or  retentions.  In  addition,  some  forms  of 
insurance  may  become  unavailable  in  the  future  or  unavailable  on  terms  that  we  believe  are  economically 
acceptable.  No  assurance  can  be  given  that  we  will  be  able  to  maintain  insurance  in  the  future  at  rates  that  we 
consider reasonable, and we may elect to maintain minimal or no insurance coverage. We may not be able to secure 
additional  insurance  or  bonding  that  might  be  required  by  new  governmental  regulations.  This  may  cause  us  to 
restrict our operations in the Gulf of Mexico, which might severely impact our financial position. The occurrence 
of a significant event, not fully insured against, could have a material adverse effect on our financial condition and 
results of operations. 

Lower oil and natural gas prices and other factors in the future may result in ceiling test write-downs and other 
impairments of our asset carrying values. 

We use the full cost method of accounting for our oil and gas operations. Accordingly, we capitalize the costs 
to acquire, explore for and develop oil and gas properties. Under the full cost method of accounting, we compare, at 
the end of each financial reporting period for each cost center, the present value of estimated future net cash flows 
from proved reserves (based on a trailing 12-month average, hedge-adjusted commodity price and excluding cash 
flows related to estimated abandonment costs), to the net capitalized costs of proved oil and gas properties, net of 
related deferred taxes. We refer to this comparison as a ceiling test. If the net capitalized costs of proved oil and gas 
properties  exceed  the  estimated  discounted  future  net  cash  flows  from  proved  reserves,  we  are  required  to  write 
down the value of our oil and gas properties to the value of the estimated discounted future net cash flows. A write-
down of oil and gas properties does not impact cash flows from operating activities, but does reduce net income. 
The  risk  that  we  are  required  to  write-down  the  carrying  value  of  oil  and  gas  properties  increases  when  oil  and 
natural gas prices are low or volatile. In addition, write-downs may occur if we experience substantial downward 
adjustments  to  our  estimated  proved  reserves  or  our  undeveloped  property  values,  or  if  estimated  future 
development costs increase. Volatility in commodity prices, poor conditions in the global economic markets and 
other factors could cause us to record additional write-downs of our oil and natural gas properties and other assets 
in the future, and incur additional charges against future earnings. Any required write-downs or impairments could 
materially affect the quantities and present value of our reserves, which could adversely affect our business, results 
of operations and financial condition. 

Our  oil  and  gas  operations  are  subject  to  various  international,  foreign  and  U.S.  federal,  state  and  local 
governmental regulations that materially affect our operations. 

Our oil and gas operations are subject to various international, foreign and U.S. federal, state and local laws 
and  regulations.  These  laws  and  regulations  may  be  changed  in  response  to  economic  or  political  conditions. 
Regulated  matters  include:  permits  for  exploration,  development  and  production  operations;  limitations  on  our 
drilling activities in environmentally sensitive areas, such as marine habitats, and restrictions on the way we can 
discharge  materials  into  the  environment;  bonds  or  other  financial  responsibility  requirements  to  cover  drilling 
contingencies and well P&A and other decommissioning costs; reports concerning operations, the spacing of wells 
and  unitization  and  pooling  of  properties;  regulations  regarding  the  rate,  terms  and  conditions  of  transportation 
service  or  the  price,  terms,  and  conditions  related  to  the  purchase  and  sale  of  oil  and  natural  gas;  and  taxation. 
Failure to comply with these laws and regulations can result in the assessment of administrative, civil or criminal 
penalties, the issuance of remedial obligations and the imposition of injunctions limiting or prohibiting certain of 
our operations. In addition, because we hold federal leases, the federal government requires that we comply with 
numerous additional regulations applicable to government contractors. 

In July 2017, we, along with partners Sierra and Premier, reported the discovery of a significant reservoir of 
crude oil in the Sureste basin offshore Mexico through the Zama-1 well. Data from the Zama-1 well indicates that 
it  is  possible  the  deposit  could  be  part  of  a  field  that  extends  into  an  exploration  block  in  which  the  state  entity 
Pemex holds exploration and development rights. 

39

6696_10K.pdf

The  Ministry  of  Energy  of  Mexico  has  promulgated  guidelines  to  establish  procedures  for  conducting  the 
unitization  of  shared  reservoirs  and  approving  the  terms  and  conditions  of  unitization  and  unit  operating 
agreements, as well as the authority to direct parties holding rights in a potentially shared reservoir to appraise and 
potentially form a unit for development of such reservoir.  

Even with the final regulations in place, there are still some uncertainties regarding the unitization process, 
including the selection of a unit operator and the exact length of time that will take to obtain approvals of any unit 
agreements. Any unit operating agreement eventually agreed to by the relevant parties or any unit order issued by a 
governmental entity in Mexico could be adverse to us and affect the value that we are able to recognize from the 
reservoir discovery, including but not limited to an agreement or unit order that would require us to allow a third 
party to develop and produce the crude oil reservoir identified through the Zama-1 well. 

In  addition,  the  OPA  requires  operators  of  U.S.  offshore  facilities  to  prove  that  they  have  the  financial 
capability to respond to costs that may be incurred in connection with potential oil spills. Under the OPA and other 
environmental statutes such as the CERCLA, the RCRA and analogous state laws, owners and operators of certain 
defined onshore and offshore facilities are strictly liable for spills of oil and other regulated substances, subject to 
certain limitations. Consequently, a spill from one of our facilities subject to laws such as the OPA, CERCLA and 
RCRA could require the expenditure of additional, and potentially significant, amounts of capital, or could have a 
material  adverse  effect  on  our  earnings,  results  of  operations,  competitive  position  or  financial  condition.  We 
cannot predict the ultimate cost of compliance with these requirements or their impact on our earnings, operations 
or competitive position. 

In September 2015, we, together with the Consortium executed a PSC with the CNH for each of Blocks 2 
and  7  of  Round  1.  The  PSCs  require  that  the  Consortium  execute  a  minimum  work  program  expressed  in  work 
units during a four-year exploration period. The work units represent the performance of exploration studies and 
seismic and drilling activities. The aggregate value of the minimum work program under the PSCs is approximately 
$143.0 million (gross), of which we are responsible for a pro rata portion based on our PI. In order to guarantee the 
execution  of  the  minimum  work  program  under  the  PSCs,  the  Consortium  was  required  to  post  a  financial 
guarantee to the CNH of approximately $143.0 million (gross), of which our share was $48.7 million. We satisfied 
our share through a performance bond. As the Consortium completes the minimum work program under the PSCs, 
the  amount  of  the  financial  guarantee  will  be  reduced  accordingly  beginning  after  the  second  anniversary  of 
entering into the PSCs. Effective January 23, 2018, the activities already performed on Block 7 have satisfied the 
minimum work program on Block 7, reducing the $143.0 million (gross) in outstanding letters of credit by $65.7 
million  (gross).  Activities  on  Block  2  are  in  the  planning  phase  and  we  are  on  schedule  to  satisfy  the  minimum 
work program on Block 2 by September 4, 2019. 

Our  Mexican  operations  are  subject  to  certain  offshore  regulatory  and  environmental  laws  and  regulations 
promulgated by Mexico. 

Our  operations  on  oil  and  natural  gas  blocks  in  shallow  waters  off  the  coast  of  Mexico’s  Veracruz  and 
Tabasco  states,  and  in  other  Mexican  offshore  areas  where  we  are  assessing  other  exploration  opportunities,  are 
subject to regulation by the SENER, the CNH and other Mexican regulatory bodies. The CNH is responsible for, 
among other things, overseeing the tender procedures for awarding contracts for the exploration and production of 
oil and natural gas in Mexican waters, managing and supervising contracts that have been awarded, and approving 
exploration  and  production  plans.  The  PSCs  that  we  and  our  consortium  partners  have  entered  into  for  the 
development  of  these  acreages  contain  terms  that  impose  on  us  the  duty  to  comply  with  various  laws  and 
regulations.  These  laws  and  regulations  govern,  among  other  things,  the  exploration  and  exploitation  of 
hydrocarbons  (including  certain  national  content  requirements),  the  treatment,  conveyance,  marketing,  transport 
and  storage  of  petroleum,  requirements  for  industrial  safety,  operational  security,  and  facility  decommissioning. 
Failure  to  comply  can  result  in  the  imposition  of  monetary  penalties,  revocation  of  permits,  rescission  of  the 
relevant PSC, suspension of operations, and ordered decommissioning of offshore facilities and systems. The laws 
and  regulations  governing  activities  in  the  Mexican  energy  sector  are  relatively  new,  having  been  significantly 
reformed in 2013, and the legal regulatory framework continues to evolve as SENER, the CNH and other Mexican 
regulatory bodies issue new regulations and guidance. Such regulations are subject to change, and it is possible that 
SENER, the CNH or other Mexican regulatory bodies may impose new or revised requirements that could increase 
our operating costs and/or capital expenditures for operations in Mexican offshore waters.

40

6696_10K.pdf

In addition, our operations on oil and natural gas blocks in shallow waters off the coast of Mexico’s Veracruz 
and Tabasco states, and in other Mexican offshore areas where we are assessing other exploration opportunities, are 
subject  to  regulation  by  the  ASEA.  We  must  obtain  ASEA-issued  permits  and  comply  with  ASEA  regulations 
governing hydrocarbon activities, including requirements for environmental impact and risk assessments, industrial 
safety, waste management, water and air emissions, operational security and facility decommissioning. Failure to 
comply  with  applicable  laws  and  regulations  can  result  in  the  imposition  of  monetary  penalties,  revocation  of 
permits, suspension of operations, and ordered decommissioning of offshore facilities and systems. The laws and 
regulations governing the protection of health, safety and the environment from activities in the Mexican energy 
sector are relatively new, having been significantly reformed in 2013 and 2014, and the legal regulatory framework 
continues  to  evolve  as  ASEA  and  other  Mexican  regulatory  bodies  issue  new  regulations  and  guidance.  Such 
regulations are subject to change, and it is possible that ASEA or other Mexican regulatory bodies may impose new 
or  revised  requirements  that  could  increase  our  operating  costs  and/or  capital  expenditures  for  operations  in 
Mexican offshore waters.

Under  the  PSCs,  we  are  also  jointly  and  severally  liable,  along  with  Sierra,  Premier  and  Hokchi,  for  the 
performance  of  all  obligations  under  the  PSCs,  including  exploration,  appraisal,  extraction  and  abandonment 
activities and compliance with all environmental regulations, and failure to perform such obligations could result in 
contractual rescission of the PSCs.

Production periods or reserve lives for Gulf of Mexico properties may subject us to higher reserve replacement 
needs and may impair our ability to reduce production during periods of low oil and natural gas prices. 

Substantially all of our operations are in the Gulf of Mexico. As a result, our reserve replacement needs from 
new  prospects  may  be  greater  than  those  of  other  oil  and  gas  companies  with  longer-life  reserves  in  other 
producing areas. Our future oil and natural gas production is highly dependent upon our level of success in finding 
or acquiring additional reserves at a unit cost that is sustainable at prevailing commodity prices. 

Exploring  for,  developing  or  acquiring  reserves  is  capital  intensive  and  uncertain.  We  may  not  be  able  to 
economically  find,  develop  or  acquire  additional  reserves  or  make  the  necessary  capital  investments  if  our  cash 
flows from operations decline or external sources of capital become limited or unavailable. Our need to generate 
revenues to fund ongoing capital commitments or repay debt may limit our ability to slow or shut-in production 
from  producing  wells  during  periods  of  low  prices  for  oil  and  natural  gas.  We  cannot  assure  you  that  our  future 
exploitation, exploration, development and acquisition activities will result in additional proved reserves or that we 
will be able to drill productive wells at acceptable costs. Further, current market conditions may adversely impact 
our ability to obtain financing to fund acquisitions, and they have lowered the level of activity and depressed values 
in the oil and natural gas property sales market. 

Our actual recovery of reserves may substantially differ from our proved reserve estimates. 

Estimates  of  our  proved  oil  and  natural  gas  reserves  and  the  estimated  future  net  cash  flows  from  such 
reserves are based upon various assumptions, including assumptions required by the SEC relating to oil and natural 
gas  prices,  drilling  and  operating  expenses,  capital  expenditures,  taxes  and  availability  of  funds.  The  process  of 
estimating oil and natural gas reserves is complex. This process requires significant decisions and assumptions in 
the  evaluation  of  available  geological,  geophysical,  engineering  and  economic  data  for  each  reservoir  and  is 
therefore  inherently  imprecise.  Additionally,  our  interpretations  of  the  rules  governing  the  estimation  of  proved 
reserves could differ from the interpretation of staff members of regulatory authorities resulting in estimates that 
could be challenged by these authorities. 

Actual  future  production,  oil  and  natural  gas  prices,  revenues,  taxes,  development  expenditures,  operating 
expenses and quantities of recoverable oil and natural gas reserves will most likely vary from those estimated. Any 
significant variance could materially affect the estimated quantities and present value of reserves. Our properties 
may  also  be  susceptible  to  hydrocarbon  drainage  from  production  by  other  operators  on  adjacent  properties.  In 
addition,  we  may  adjust  estimates  of  proved  reserves  to  reflect  production  history,  results  of  exploration  and 
development, prevailing oil and natural gas prices and other factors, many of which are beyond our control. 

41

6696_10K.pdf

You should not assume that any present value of future net cash flows from our proved reserves represents 
the market value of our estimated oil and natural gas reserves. We base the estimated discounted future net cash 
flows  from  our  proved  reserves  at  December 31,  2018  on  historical  12-month  average  prices  and  costs  as  of  the 
date  of  the  estimate.  Actual  future  prices  and  costs  may  be  materially  higher  or  lower.  Further,  actual  future  net 
revenues are affected by factors such as: 

•

•

the amount and timing of capital expenditures and decommissioning costs; 

the rate and timing of production; 

• changes in governmental regulations or taxation; 

• volume, pricing and duration of our oil and natural gas hedging contracts; 

• supply of and demand for oil and natural gas; 

• actual prices we receive for oil and natural gas; and 

• our actual operating costs in producing oil and natural gas. 

The timing of both our production and our incurrence of expenses in connection with the development and 
production  of  oil  and  natural  gas  properties  affects  the  timing  of  actual  future  net  cash  flows  from  reserves,  and 
thus their actual present value. In addition, the 10% discount factor that we use to calculate the net present value of 
future net revenues and cash flows may not necessarily be the most appropriate discount factor based on our cost of 
capital in effect from time to time and the risks associated with our business and the oil and gas industry in general. 

At December 31, 2018, approximately 24% of our estimated proved reserves (by volume) were undeveloped 
and approximately 25% were non-producing. Any or all of our PUD or proved developed non-producing reserves 
may  not  be  ultimately  developed  or  produced.  Furthermore,  any  or  all  of  our  undeveloped  and  developed  non-
producing  reserves  may  not  be  ultimately  produced  during  the  time  periods  we  plan  or  at  the  costs  we  budget, 
which could result in the write-off of previously recognized reserves. Recovery of undeveloped reserves generally 
requires  significant  capital  expenditures  and  successful  drilling  operations.  Our  reserve  estimates  include  the 
assumptions  that  we  incur  capital  expenditures  to  develop  these  undeveloped  reserves  and  the  actual  costs  and 
results  associated  with  these  properties  may  not  be  as  estimated.  Any  material  inaccuracies  in  these  reserve 
estimates or underlying assumptions materially affects the quantities and present value of our reserves, which could 
adversely affect our business, results of operations and financial condition. 

Three-dimensional  seismic  interpretation  does  not  guarantee  that  hydrocarbons  are  present  or  if  present 
produce in economic quantities. 

We rely on 3D seismic studies to assist us with assessing prospective drilling opportunities on our properties, 
as  well  as  on  properties  that  we  may  acquire.  Such  seismic  studies  are  merely  an  interpretive  tool  and  do  not 
necessarily  guarantee  that  hydrocarbons  are  present  or,  if  present,  produce  in  economic  quantities,  and  seismic 
indications  of  hydrocarbon  saturation  are  generally  not  reliable  indicators  of  productive  reservoir  rock.  These 
limitations  of  3D  seismic  data  may  impact  our  drilling  and  operational  results,  and  consequently  our  financial 
condition. 

SEC rules could limit our ability to book additional PUD reserves in the future. 

SEC  rules  require  that,  subject  to  limited  exceptions,  PUD  reserves  may  only  be  booked  if  they  relate  to 
wells scheduled to be drilled within five years after the date of booking. This requirement may limit our ability to 
book additional PUD reserves as we pursue our drilling program. Moreover, we may be required to write down our 
PUD reserves if we do not drill those wells within the required five-year timeframe. 

Our acreage has to be drilled before lease expiration in order to hold the acreage by production. If commodity 
prices become depressed for an extended period of time, it might not be economical for us to drill sufficient wells 
in  order  to  hold  acreage,  which  could  result  in  the  expiry  of  a  portion  of  our  acreage,  which  could  have  an 
adverse effect on our business. 

Unless production is established as required by the leases covering the undeveloped acres, the leases for such 

acreage may expire. 

42

6696_10K.pdf

Our drilling plans for areas not held by production are subject to change based upon various factors. Many of 
these factors are beyond our control, including drilling results, oil and natural gas prices, the availability and cost of 
capital, drilling and production costs, availability of drilling services and equipment, gathering system and pipeline 
transportation  constraints  and  regulatory  approvals.  On  the  acreage  that  we  do  not  operate,  we  have  less  control 
over the timing of drilling, and therefore there is additional risk of expirations occurring in those sections. 

The  marketability  of  our  production  depends  mostly  upon  the  availability,  proximity,  and  capacity  of  oil  and 
natural gas gathering systems, pipelines and processing facilities. 

The marketability of our production depends upon the availability, proximity, operation and capacity of oil 
and natural gas gathering systems, pipelines and processing facilities. The lack of availability or capacity of these 
gathering systems, pipelines and processing facilities could result in the shut-in of producing wells or the delay or 
discontinuance  of  development  plans  for  properties.  The  disruption  of  these  gathering  systems,  pipelines  and 
processing facilities due to maintenance and/or weather could negatively impact our ability to market and deliver 
our  products.  Federal,  state,  and  local  regulation  of  oil  and  natural  gas  production  and  transportation,  general 
economic conditions, and changes in supply and demand could adversely affect our ability to produce and market 
our  oil  and  natural  gas.  If  market  factors  changed  dramatically,  the  financial  impact  could  be  substantial.  The 
availability of markets and the volatility of product prices are beyond our control and represent a significant risk. 

Our actual production could differ materially from our forecasts. 

From time to time, we may provide forecasts of expected quantities of future oil and gas production. These 
forecasts are based on a number of estimates, including expectations of production from existing wells. In addition, 
our forecasts may assume that none of the risks associated with our oil and natural gas operations summarized in 
this section would occur, such as facility or equipment malfunctions, adverse weather effects or significant declines 
in commodity prices or material increases in costs, which could make certain production uneconomical. 

Our operations are subject to numerous risks of oil and natural gas drilling and production activities. 

Oil  and  gas  drilling  and  production  activities  are  subject  to  numerous  risks,  including  the  risk  that  no 
commercially productive oil or natural gas reserves are found. The cost of drilling and completing wells is often 
uncertain. To the extent we drill additional wells in the Gulf of Mexico deepwater and/or in the Gulf Coast deep 
gas,  our  drilling  activities  increases  capital  cost.  In  addition,  the  geological  complexity  of  the  areas  in  which  we 
have oil and natural gas operations make it more difficult for us to sustain the historical rates of drilling success. 
Oil and natural gas drilling and production activities may be shortened, delayed or cancelled as a result of a variety 
of factors, many of which are beyond our control. These factors include: 

• unexpected drilling conditions; 

• pressure or irregularities in formations; 

• equipment failures or accidents; 

• hurricanes and other adverse weather conditions; 

• shortages in experienced labor; and 

• shortages or delays in the delivery of equipment. 

The prevailing prices of oil and natural gas also affect the cost of and the demand for drilling rigs, production 
equipment  and  related  services.  We  cannot  assure  you  that  the  wells  we  drill  will  be  productive  or  that  we  will 
recover all or any portion of our investment. Drilling for oil and natural gas may be unprofitable. Drilling activities 
can  result  in  dry  holes  and  wells  that  are  productive  but  do  not  produce  sufficient  cash  flows  to  recoup  drilling 
costs. 

Our industry experiences numerous operating risks. 

The exploration, development and production of oil and gas properties involves a variety of operating risks, 
including the risk of fire, explosions, blowouts, pipe failure, abnormally pressured formations and environmental 
hazards. Environmental hazards include oil spills, gas leaks, pipeline ruptures or discharges of toxic gases. We are 
also involved in completion operations that utilize hydraulic fracturing, which may potentially present additional 
operational and environmental risks. Additionally, our offshore operations are subject to the additional hazards of 
marine  operations,  such  as  capsizing,  collisions  and  adverse  weather  and  sea  conditions,  including  the  effects  of 
hurricanes. 

43

6696_10K.pdf

In  addition,  an  oil  spill  on  or  related  to  our  properties  and  operations  could  expose  us  to  joint  and  several 
strict liability, without regard to fault, under applicable law for containment and oil removal costs and a variety of 
public  and  private  damages,  including,  but  not  limited  to,  the  costs  of  responding  to  a  release  of  oil,  natural 
resource damages and economic damages suffered by persons adversely affected by an oil spill. If an oil discharge 
or substantial threat of discharge were to occur, we could be liable for costs and damages, which costs and damages 
could be material to our results of operations and financial position. 

Our business is also subject to the risks and uncertainties normally associated with the exploration for and 
development  and  production  of  oil  and  natural  gas  that  are  beyond  our  control,  including  uncertainties  as  to  the 
presence, size and recoverability of hydrocarbons. We may not encounter commercially productive oil and natural 
gas  reservoirs.  We  may  not  recover  all  or  any  portion  of  our  investment  in  new  wells.  The  presence  of 
unanticipated pressures or irregularities in formations, miscalculations or accidents may cause our drilling activities 
to be unsuccessful and/or result in a total loss of our investment, which could have a material adverse effect on our 
financial condition, results of operations and cash flows. In addition, we may be uncertain as to the future cost or 
timing of drilling, completing and operating wells. 

We  have  an  interest  in  deepwater  fields  and  may  attempt  to  pursue  additional  operational  activity  in  the 
future  and  acquire  additional  fields  and  leases  in  the  deepwaters  of  the  Gulf  of  Mexico.  Exploration  for  oil  or 
natural gas in the deepwater of the Gulf of Mexico generally involves greater operational and financial risks than 
exploration on the Gulf of Mexico Conventional Shelf. Deepwater drilling generally requires more time and more 
advanced  drilling  technologies,  involving  a  higher  risk  of  technological  failure  and  usually  higher  drilling  costs. 
For  example,  the  drilling  of  deepwater  wells  requires  specific  types  of  drilling  rigs  with  significantly  higher  day 
rates  and  limited  availability  as  compared  to  the  rigs  used  in  shallower  water.  Deepwater  wells  often  use  subsea 
completion techniques with subsea trees tied back to host production facilities with flow lines. The installation of 
these subsea trees and flow lines requires substantial time and the use of advanced remote installation mechanics. 
These operations may encounter mechanical difficulties and equipment failures that could result in cost overruns. 
Furthermore, the deepwater operations generally lack the physical and oilfield service infrastructure present on the 
Gulf of Mexico Conventional Shelf. As a result, a considerable amount of time may elapse between a deepwater 
discovery and the marketing of the associated oil or natural gas, increasing both the financial and operational risk 
involved with these operations. Because of the lack and high cost of infrastructure, some reserve discoveries in the 
deepwater may never be produced economically. 

If  any  of  these  industry  operating  risks  occur,  we  could  have  substantial  losses.  Substantial  losses  may  be 
caused  by  injury  or  loss  of  life,  severe  damage  to  or  destruction  of  property,  natural  resources  and  equipment, 
pollution  or  other  environmental  damage,  clean-up  responsibilities,  regulatory  investigation  and  penalties, 
suspension  of  operations  and  production  and  repairs  to  resume  operations.  Any  of  these  industry  operating  risks 
could have a material adverse effect on our business, results of operations and financial condition. 

Our  business  could  be  negatively  affected  by  security  threats,  including  cybersecurity  threats,  terrorist 

attacks and other disruptions. 

As  an  oil  and  gas  producer,  we  have  various  security  threats,  including  cybersecurity  threats  to  gain 
unauthorized  access  to  sensitive  information  or  to  render  data  or  systems  unusable,  threats  to  the  security  of  our 
facilities and infrastructure or third-party facilities and infrastructure, such as processing plants and pipelines, and 
threats  from  terrorist  acts.  The  potential  for  such  security  threats  subjects  our  operations  to  increased  risks  that 
could have a material adverse effect on our business. In particular, the implementation of various procedures and 
controls  to  monitor  and  mitigate  security  threats  and  to  increase  security  for  our  information,  facilities  and 
infrastructure  may  result  in  increased  capital  and  operating  costs.  Moreover,  there  can  be  no  assurance  that  such 
procedures and controls are sufficient to prevent security breaches from occurring. If any of these security breaches 
were to occur, they could lead to losses of sensitive information, critical infrastructure or capabilities essential to 
our operations and could have a material adverse effect on our reputation, financial position, results of operations 
or cash flows. Cybersecurity attacks in particular are becoming more sophisticated and include, but are not limited 
to,  malicious  software,  attempts  to  gain  unauthorized  access  to  data  and  systems  and  other  electronic  security 
breaches  that  could  lead  to  disruptions  in  critical  systems,  unauthorized  release  of  confidential  or  otherwise 
protected information and corruption of data. These events could damage our reputation and lead to financial losses 
from remedial actions, loss of business or potential liability.

The  U.S.  government  has  issued  warnings  that  U.S.  energy  assets  may  be  the  future  targets  of  terrorist 
organizations.  These  developments  subject  our  operations  to  increased  risks.  Any  future  terrorist  attack  at  our 
facilities, or those of our purchasers or vendors, could have a material adverse effect on our financial condition and 
operations. 

Our  estimates  of  future  asset  retirement  obligations  may  vary  significantly  from  period  to  period  and 
unanticipated decommissioning costs could materially adversely affect our future financial position and results 
of operations. 

We are required to record a liability for the discounted present value of our asset retirement obligations to 
plug  and  abandon  inactive,  non-producing  wells,  to  remove  inactive  or  damaged  platforms,  facilities  and 
equipment, and to restore the land or seabed at the end of oil and natural gas operations. These costs are typically 
considerably more expensive for offshore operations as compared to most land-based operations due to increased 
regulatory scrutiny and the logistical issues associated with working in waters of various depths. Estimating future 
restoration and removal costs in the Gulf of Mexico is especially difficult because most of the removal obligations 
may be many years in the future, regulatory requirements are subject to change or more restrictive interpretation, 
and asset removal technologies are constantly evolving, which may result in additional or increased or decreased 
costs.  As  a  result,  we  may  significantly  increase  or  decrease  our  estimated  asset  retirement  obligations  in  future 
periods. For example, because we operate in the Gulf of Mexico, platforms, facilities and equipment are subject to 
damage or destruction as a result of hurricanes and other adverse weather conditions. The estimated costs to plug 
and abandon a well or dismantle a platform can change dramatically if the host platform from which the work was 
anticipated  to  be  performed  is  damaged  or  toppled  rather  than  structurally  intact.  Accordingly,  our  estimates  of 
future  asset  retirement  obligations  could  differ  dramatically  from  what  we  may  ultimately  incur  as  a  result  of 
damage  from  a  hurricane  or  other  natural  disaster.  Also,  a  sustained  lower  commodity  price  environment  may 
cause  our  non-operator  partners  to  be  unable  to  pay  their  share  of  costs,  which  may  require  us  to  pay  our 
proportionate share of the defaulting party’s share of costs. 

Moreover, the timing for pursuing restoration and removal activities has accelerated for operators in the U.S 
Gulf  of  Mexico  following  BSEE’s  issuance  of  an  NTL  that  established  a  more  stringent  regimen  for  the  timely 
decommissioning of what is known as “idle iron” wells, which are wells, platforms and pipelines that are no longer 
producing or serving exploration or support functions with respect to an operator’s lease in the Gulf of Mexico. The 
idle iron NTL, which was initially issued in 2010 and re-issued with a more streamline framework in December 
2018,  requires  decommissioning  of  any  well  that  has  not  been  used  during  the  past  five  years  for  exploration  or 
production  on  active  leases  and  is  no  longer  capable  of  producing  in  paying  quantities,  which  must  then  be 
permanently plugged or temporarily abandoned within three years’ time. Similarly, platforms or other facilities no 
longer  useful  for  operations  must  be  removed  within  five  years  of  the  cessation  of  operations.  We  may  have  to 
draw  on  funds  from  other  sources  to  satisfy  decommissioning  costs.  The  use  of  other  funds  to  satisfy  such 
decommissioning  costs  could  have  a  material  adverse  effect  on  our  financial  position  and  results  of  operations. 
Moreover,  as  a  result  of  the  implementation  of  the  idle  iron  NTL,  there  is  expected  to  be  increased  demand  for 
salvage contractors and equipment operating in the Gulf of Mexico, resulting in increased estimates of plugging, 
abandonment and removal costs and associated increases in operators’ asset retirement obligations. 

In addition, we could become responsible for decommissioning liabilities related to offshore facilities we no 
longer  own  or  operate.  Under  existing  BOEM  rules  relating  to  assignment  of  offshore  leases  and  other  legal 
interests  on  the  OCS,  assignors  of  such  interest  may  be  held  jointly  and  severally  liable,  regardless  of  any 
indemnity agreements, for decommissioning of OCS facilities existing at the time the assignment was approved by 
the BOEM in the event that the assignee, or any subsequent assignee, is unable or unwilling to conduct required 
decommissioning obligations. The costs of performance of required decommissioning obligations, whether our or 
any  assignees,  may  be  material.    Moreover,  several  onshore  and  offshore  exploration  and  production  companies 
have  sought  bankruptcy  protection  over  the  past  several  years.  The  government  may  seek  to  impose  a  bankrupt 
entity’s  P&A  obligations  on  us  or  other  predecessors-in-interest,  which  could  be  significant  and  have  a  material 
adverse effect on our business, results of operations, financial condition and cash flows. 

We may not receive payment for a portion of our future production. 

We may not receive payment for a portion of our future production. We attempt to diversify our sales and 
obtain credit protections, such as parent guarantees, from certain of our purchasers. The tightening of credit in the 
financial  markets  may  make  it  more  difficult  for  customers  to  obtain  financing  and,  depending  on  the  degree  to 
which this occurs, there may be a material increase in the nonpayment and nonperformance by customers. We are 
unable  to  predict  what  impact  the  financial  difficulties  of  certain  purchasers  may  have  on  our  future  results  of 
operations and liquidity.

The market price of our common stock may decline as a result of the Stone Combination.

The  market  price  of  our  common  stock  may  decline  as  a  result  of  the  Stone  Combination  if,  among  other 
things, we are unable to achieve the expected benefits of the transaction, or if the transaction costs related to the 
Stone  Combination  and  integration  are  greater  than  expected.  The  market  price  also  may  decline  if  we  do  not 
achieve  the  perceived  benefits  of  the  Stone  Combination  as  rapidly  or  to  the  extent  anticipated  by  financial  or 
industry  analysts  or  if  the  effect  of  the  Stone  Combination  on  our  financial  results  is  not  consistent  with  the 
expectations of financial or industry analysts.

We  may  not  realize  all  of  the  anticipated  benefits  from  our  future  acquisitions,  and  we  may  be  unable  to 
successfully integrate future acquisitions. 

Our growth strategy will, in part, rely on acquisitions. We have to plan and manage acquisitions effectively 
to achieve revenue growth and maintain profitability in our evolving market. We expect to grow in the future by 
expanding  the  exploitation  and  development  of  our  existing  assets,  in  addition  to  growing  through  targeted 
acquisitions in the Gulf of Mexico or in other basins. We may not realize all of the anticipated benefits from our 
future  acquisitions,  such  as  increased  earnings,  cost  savings  and  revenue  enhancements,  for  various  reasons, 
including difficulties integrating operations and personnel, higher than expected acquisition and operating costs or 
other  difficulties,  inexperience  with  operating  in  new  geographic  regions,  unknown  liabilities,  inaccurate  reserve 
estimates and fluctuations in market prices. 

In addition, integrating acquired businesses and properties involves a number of special risks and unforeseen 
difficulties  can  arise  in  integrating  operations  and  systems  and  in  retaining  and  assimilating  employees.  These 
difficulties include, among other things: 

• operating a larger organization; 

• coordinating geographically disparate organizations, systems and facilities; 

•

integrating corporate, technological and administrative functions; 

• diverting management’s attention from regular business concerns; 

• diverting financial resources away from existing operations; 

•

•

increasing our indebtedness; and 

incurring potential environmental or regulatory liabilities and title problems. 

Any  of  these  or  other  similar  risks  could  lead  to  potential  adverse  short-term  or  long-term  effects  on  our 
operating results. The process of integrating our operations could cause an interruption of, or loss of momentum in, 
the  activities  of  our  business.  Members  of  our  management  may  be  required  to  devote  considerable  amounts  of 
time to this integration process, which decreases the time they have to manage our business. If our management is 
not able to effectively manage the integration process, or if any business activities are interrupted as a result of the 
integration process, our business could suffer. 

Our future acquisitions could expose us to potentially significant liabilities, including P&A liabilities. 

We  expect  that  future  acquisitions  will  contribute  to  our  growth.  In  connection  with  potential  future 

acquisitions, we may only be able to perform limited due diligence. 

Successful  acquisitions  of  oil  and  natural  gas  properties  require  an  assessment  of  a  number  of  factors, 
including estimates of recoverable reserves, the timing of recovering reserves, exploration potential, future oil and 
natural  gas  prices,  operating  costs  and  potential  environmental,  regulatory  and  other  liabilities,  including  P&A 
liabilities. Such assessments are inexact and may not disclose all material issues or liabilities. In connection with 
our  assessments,  we  perform  a  review  of  the  acquired  properties.  However,  such  a  review  may  not  reveal  all 
existing or potential problems. In addition, our review may not permit us to become sufficiently familiar with the 
properties to fully assess their deficiencies and capabilities. 

There  may  be  threatened,  contemplated,  asserted  or  other  claims  against  the  acquired  assets  related  to 
environmental,  title,  regulatory,  tax,  contract,  litigation  or  other  matters  of  which  we  are  unaware,  which  could 
materially  and  adversely  affect  our  production,  revenues  and  results  of  operations.  We  may  be  successful  in 
obtaining  contractual  indemnification  for  preclosing  liabilities,  including  environmental  liabilities,  but  we  expect 
that  we  will  generally  acquire  interests  in  properties  on  an  “as  is”  basis  with  limited  remedies  for  breaches  of 
representations  and  warranties.  In  addition,  even  if  we  are  able  to  obtain  such  indemnification  from  the  sellers, 
these  indemnification  obligations  usually  expire  over  time  and  could  potentially  expose  us  to  unindemnified 
liabilities, which could materially adversely affect our production, revenues and results of operations.

We may be exposed to liabilities under the U.S. Foreign Corrupt Practices Act (the “FCPA”). 

We are subject to the FCPA and other laws that prohibit improper payments or offers of payments to foreign 
governments and their officials and political parties for the purpose of obtaining or retaining business. We may do 
business  in  the  future  in  countries  and  regions  in  which  we  may  face,  directly  or  indirectly,  corrupt  demands  by 
officials, tribal or insurgent organizations, or private entities. Thus, we face the risk of unauthorized payments or 
offers of payments by one of our employees or consultants, given that these parties may not always be subject to 
our  control.  Our  existing  safeguards  and  any  future  improvements  may  prove  to  be  less  than  effective,  and  our 
employees and consultants may engage in conduct for which we might be held responsible. 

Under the PSCs with the CNH, we work as a consortium with other partners: Sierra, Premier and Hokchi. 
Violations of the FCPA, by any consortium partner, may result in severe criminal or civil sanctions, and we may be 
subject to other liabilities, which could negatively affect our business, operating results and financial condition. In 
addition, the CNH has the authority to rescind the PSCs if these violations occur. 

Our operations may be adversely affected by political and economic circumstances in the countries in which we 
operate. 

Our  oil  and  gas  exploration,  development  and  production  activities  are  subject  to  political  and  economic 
uncertainties  (including  but  not  limited  to  changes,  sometimes  frequent  or  marked,  in  energy  policies  or  the 
personnel administering them), expropriation of property, cancellation or modification of contract rights, changes 
in  laws  and  policies  governing  operations  of  foreign-based  companies,  unilateral  renegotiation  of  contracts  by 
governmental entities, redefinition of international boundaries or boundary disputes, foreign exchange restrictions, 
currency fluctuations, royalty and tax increases, and other risks arising out of governmental sovereignty over the 
areas in which our operations are conducted, as well as risks of loss due to acts of terrorism, piracy, disease, illegal 
cartel  activities  and  other  political  risks,  including  tension  and  confrontations  among  political  parties.  Some  of 
these  risks  may  be  higher  in  the  developing  countries  in  which  we  conduct  our  activities,  namely,  Mexico. 
Mexico’s  most  recent  presidential  election  was  held  in  July  2018.  Presidential  reelection  is  not  permitted  in 
Mexico.  President  Andrés  Manuel  López  Obrador,  took  office  on  December  1,  2018,  and  his  political  party, 
Movimiento Regeneración Nacional has a majority in both houses of Mexico’s congress. Mr. Lopez Obrador, and 
certain  members  of  his  cabinet  have,  in  the  past,  made  statements  that  would  call  into  question  the  degree  of 
support their administration will have for Mexico’s energy reforms. However, at this time we cannot predict what 
changes (if any) will result from this change in administration. Political events in Mexico could adversely affect 
economic  conditions  and/or  the  oil  and  gas  industry  and,  by  extension,  our  results  of  operations  and  financial 
position. 

Our  operations  may  be  exposed  to  risks  of  illegal  cartel  activities,  local  economic  conditions,  political 

disruption, and governmental policies that may: 

• disrupt our operations; 

•

•

•

restrict the movement of funds or limit repatriation of profits; 

in the case of our non-U.S. operations, lead to U.S. government or international sanctions; and 

limit access to markets for periods of time. 

Disruptions may occur in the future, and losses caused by these disruptions may not be covered by insurance. 
Consequently, our exploration, development and production activities may be substantially affected by factors that 
could have a material adverse effect on our financial condition and results of operations. Furthermore, in the event 
of a dispute arising from non-U.S. operations, we may be subject to the exclusive jurisdiction of courts outside the 
United States or may not be successful in subjecting non-U.S. persons to the jurisdiction of courts in the United 
States, which could adversely affect the outcome of such dispute. 

Our operations are adversely affected by laws and policies of the jurisdictions, including Mexico, the United 
States,  the  Netherlands  and  other  jurisdictions,  in  which  we  do  business  that  affect  foreign  trade  and  taxation. 
Changes in any of these laws or policies or the implementation thereof could have a material adverse effect on our 
results of operations and financial position.

New technologies may cause our current exploration and drilling methods to become obsolete, and we may not 
be able to keep pace with technological developments in our industry. 

The oil and natural gas industry is subject to rapid and significant advancements in technology, including the 
introduction  of  new  products  and  services  using  new  technologies.  As  competitors  use  or  develop  new 
technologies,  we  may  be  placed  at  a  competitive  disadvantage,  and  competitive  pressures  may  force  us  to 
implement  new  technologies  at  a  substantial  cost.  In  addition,  competitors  may  have  greater  financial,  technical, 
and personnel resources that allow them to enjoy technological advantages and that may in the future allow them to 
implement new technologies before we can. We rely heavily on the use of seismic technology to identify low-risk 
development  and  exploitation  opportunities  and  to  reduce  our  geological  risk.  Seismic  technology  or  other 
technologies that we may implement in the future may become obsolete. We cannot be certain that we will be able 
to  implement  technologies  on  a  timely  basis  or  at  a  cost  that  is  acceptable  to  us.  If  we  are  unable  to  maintain 
technological  advancements  consistent  with  industry  standards,  our  business,  results  of  operations  and  financial 
condition may be materially adversely affected. 

We  may  not  be  in  a  position  to  control  the  timing  of  development  efforts,  the  associated  costs  or  the  rate  of 
production of the reserves from our non-operated properties. 

As  we  carry  out  our  drilling  program,  we  may  not  serve  as  operator  of  all  planned  wells.  We  may  have 
limited ability to exercise influence over the operations of some non-operated properties and their associated costs. 
Our dependence on the operator and other working interest owners and our limited ability to influence operations 
and associated costs of properties operated by others could prevent the realization of anticipated results in drilling 
or acquisition activities. The success and timing of development and exploitation activities on properties operated 
by others depends upon a number of factors that could be largely outside of our control, including: 

•

•

•

the timing and amount of capital expenditures; 

the  availability  of  suitable  offshore  drilling  rigs,  drilling  equipment,  support  vessels,  production  and 
transportation infrastructure and qualified operating personnel; 

the operator’s expertise and financial resources; 

• approval of other participants in drilling wells; 

•

risk of other non-operator’s failing to pay its share of costs, which may require us to pay our proportionate 
share of the defaulting party’s share of costs; 

• selection of technology; 

•

•

the rate of production of the reserves; and 

the timing and cost of P&A operations. 

In addition, with respect to oil and natural gas projects that we do not operate, we have limited influence over 
operations, including limited control over the maintenance of safety and environmental standards. The operators of 
those properties may, depending on the terms of the applicable joint operating agreement: 

•

•

refuse to initiate exploration or development projects; 

initiate exploration or development projects on a slower or faster schedule than we would prefer; 

• delay the pace of exploratory drilling or development; and/or 

• drill more wells or build more facilities on a project than we can afford, whether on a cash basis or through 
financing, which may limit our participation in those projects or limit the percentage of our revenues from 
those projects. 

The  occurrence  of  any  of  the  foregoing  events  could  have  a  material  adverse  effect  on  our  anticipated 

exploration and development activities. 

48

6696_10K.pdf

Competition within our industry may adversely affect our operations. 

Competition within our industry is intense, particularly with respect to the acquisition of producing properties 
and  undeveloped  acreage.  We  compete  with  major  oil  and  gas  companies  and  other  independent  producers  of 
varying sizes, all of which are engaged in the acquisition of properties and the exploration and development of such 
properties.  Many  of  our  competitors  have  financial  resources  and  exploration  and  development  budgets  that  are 
substantially  greater  than  our  budget,  which  may  adversely  affect  our  ability  to  compete.  If  other  companies 
relocate  to  the  Gulf  of  Mexico  region,  levels  of  competition  may  increase  and  our  business  could  be  adversely 
affected. In the exploration and production business, some of the larger integrated companies may be better able 
than we are to respond to industry changes including price fluctuations, oil and gas demand, political change and 
government regulations. 

We  actively  compete  with  other  companies  when  acquiring  new  leases  or  oil  and  gas  properties.  For 
example, new leases acquired from BOEM are acquired through a “sealed bid” process and are generally awarded 
to  the  highest  bidder.  These  additional  resources  can  be  particularly  important  in  reviewing  prospects  and 
purchasing properties. The competitors may also have a greater ability to continue drilling activities during periods 
of low oil and gas prices, such as the current decline in oil prices, and to absorb the burden of current and future 
governmental regulations and taxation. Competitors may be able to evaluate, bid for and purchase a greater number 
of properties and prospects than our financial or personnel resources permit. Competitors may also be able to pay 
more for productive oil and gas properties and exploratory prospects than we are able or willing to pay. Further, our 
competitors  may  be  able  to  expend  greater  resources  on  the  existing  and  changing  technologies  that  we  believe 
impacts attaining success in the industry. If we are unable to compete successfully in these areas in the future, our 
future revenues and growth may be diminished or restricted. 

The  loss  of  our  larger  customers  could  materially  reduce  our  revenue  and  materially  adversely  affect  our 
business, financial condition and results of operations. 

We  have  a  limited  number  of  customers  that  provide  a  substantial  portion  of  our  revenue.  The  loss  of  our 
larger  customers,  including  Shell  Trading  (US)  Company,  could  adversely  affect  our  current  and  future  revenue, 
and could have a material adverse effect on our business, financial condition and results of operations. 

Our  business  depends  on  access  to  oil  and  natural  gas  processing,  gathering  and  transportation  systems  and 
facilities. 

The marketability of our oil and natural gas production depends in large part on the operation, availability, 
proximity, capacity and expansion of processing, gathering and transportation facilities owned by third parties. We 
can provide no assurance that sufficient processing, gathering and/or transportation capacity exists or that we will 
be  able  to  obtain  sufficient  processing,  gathering  and/or  transportation  capacity  on  economic  terms.  A  lack  of 
available capacity on processing, gathering and transportation facilities or delays in their planned expansions could 
result  in  the  shut-in  of  producing  wells  or  the  delay  or  discontinuance  of  drilling  plans  for  properties.  A  lack  of 
availability of these facilities for an extended period of time could negatively impact our revenues. In addition, we 
enter  into  contracts  for  firm  transportation,  and  any  failure  to  renew  those  contracts  on  the  same  or  better 
commercial  terms  could  increase  our  costs  and  our  exposure  to  the  risks  described  above.  In  addition,  the  rates 
charged for processing, gathering and transportation services may increase over time. 

The loss of key personnel could adversely affect our ability to operate. 

Our  industry  has  lost  a  significant  number  of  experienced  professionals  over  the  years  due  to  its  cyclical 
nature,  which  is  attributable,  among  other  reasons,  to  the  volatility  in  commodity  prices.  Our  operations  are 
dependent upon key management and technical personnel. We cannot assure you that individuals will remain with 
us for the immediate or foreseeable future. The unexpected loss of the services of one or more of these individuals 
could have an adverse effect on us and our operations. 

In  addition,  our  exploration,  production  and  decommissioning  activities  require  personnel  with  specialized 
skills  and  experience.  As  a  result,  our  ability  to  remain  productive  and  profitable  depends  upon  our  ability  to 
employ and retain skilled workers. Our ability to expand operations depends in part on our ability to increase the 
size of our skilled labor force, including geologists and geophysicists, field operations managers and engineers, to 
handle all aspects of our exploration, production and decommissioning activities. The demand for skilled workers 
in our industry is high, and the supply is limited. A significant increase in the wages paid by competing employers 
or the unionization of our Gulf of Mexico employees could result in a reduction of our labor force, increases in the 
wage rates that we will have to pay, or both. If either of these events were to occur, our capacity and profitability 
could be diminished and our growth potential could be impaired.

Resolution of litigation could materially affect our financial position and results of operations. 

Resolution of litigation could materially affect our financial position and results of operations. To the extent 
that potential exposure to liability is not covered by insurance or insurance coverage is inadequate, we may incur 
losses that could be material to our financial position or results of operations in future periods. 

We have operations in multiple jurisdictions, including jurisdictions in which the tax laws, their interpretation 
or their administration may change. As a result, our tax obligations and related filings are complex and subject 
to  change,  and  our  after-tax  profitability  could  be  lower  than  anticipated.  Additionally,  political  events  in  the 
United States or Mexico could result in changes to the taxation of our income and operations, which could also 
adversely impact our after-tax profitability.

We  are  subject  to  income,  withholding  and  other  taxes  in  the  United  States  on  a  worldwide  basis  and  in 
numerous  state,  local  and  foreign  jurisdictions  with  respect  to  our  income  and  operations  related  to  those 
jurisdictions.  Our  after-tax  profitability  could  be  affected  by  numerous  factors,  including  the  availability  of  tax 
credits, exemptions and other benefits to reduce our tax liabilities, changes in the relative amount of our earnings 
subject  to  tax  in  the  various  jurisdictions  in  which  we  operate,  the  potential  expansion  of  our  business  into  or 
otherwise  becoming  subject  to  tax  in  additional  jurisdictions,  changes  to  our  existing  business  structure  and 
operations, the extent of our intercompany transactions and the extent to which taxing authorities in the relevant 
jurisdictions respect those intercompany transactions.

Our after-tax profitability may also be affected by changes in the relevant tax laws and tax rates, regulations, 
administrative  practices  and  principles,  judicial  decisions,  and  interpretations,  in  each  case,  possibly  with 
retroactive effect. The United States recently enacted tax reform legislation in Public Law No. 115-97, commonly 
referred  to  as  the  Tax  Cuts  and  Jobs  Act.  Additionally,  the  Multilateral  Convention  to  Implement  Tax  Treaty 
Related Measures to Prevent BEPS recently entered into force among the jurisdictions that have ratified it. Both of 
these recent changes could result in further changes to our global taxation. These tax reforms provided for new and 
complex  provisions  that  significantly  change  how  the  United  States  and  other  jurisdictions  tax  entities  and 
operations,  and  those  provisions  are  subject  to  further  legislative  change  and  administrative  guidance  and 
interpretation,  all  of  which  may  differ  from  our  interpretation.  Additionally,  Mexico  recently  elected  a  new 
president, Andrés Manuel López Obrador, who took office on December 1, 2018. His political party, Movimiento 
Regeneración  Nacional,  has  a  majority  in  both  houses  of  Mexico’s  congress.  However,  it  is  unclear  at  this  time 
what changes (if any) to the taxation of our income and operations will result from these political events in Mexico. 
Future tax reforms in Mexico as a result of these political events or in any other jurisdictions in which we operate 
now or in the future could also adversely impact our after-tax profitability. 

Future  regulations  relating  to  and  interpretations  of  recently  enacted  U.S.  federal  income  tax  legislation  may 
vary from our current interpretation of such legislation.

The U.S. federal income tax legislation recently enacted in Public Law No. 115-97, commonly referred to as 
the  Tax  Cuts  and  Jobs  Act,  is  highly  complex  and  subject  to  interpretation.  The  presentation  of  our  financial 
condition and results of operations is based upon our current interpretation of the provisions contained in the Tax 
Cuts and Jobs Act. In the future, the Treasury Department and the Internal Revenue Service are expected to release 
regulations  relating  to  and  interpretive  guidance  of  the  legislation  contained  in  the  Tax  Cuts  and  Jobs  Act.  Any 
significant  variance  of  our  current  interpretation  of  such  legislation  from  any  future  regulations  or  interpretive 
guidance could result in a change to the presentation of our financial condition and results of operations and could 
negatively affect our business.

Climate  change  legislation  or  regulations  restricting  emissions  of  GHGs  could  result  in  increased  operating 
costs and reduced demand for the crude oil and natural gas that we produce. 

Climate  change  continues  to  attract  considerable  public  and  scientific  attention.  As  a  result,  numerous 
proposals have been made and could continue to be made at the international, national, regional and state levels of 
government to monitor and limit emissions of GHGs. These efforts have included consideration of cap-and-trade 
programs, carbon taxes, GHG reporting and tracking programs, and regulations that directly limit GHG emissions 
from certain sources. At the federal level, no comprehensive climate change legislation has been implemented. The 
EPA,  however,  has  adopted  regulations  to  restrict  emissions  of  GHGs  under  existing  provisions  of  the  federal 
CAA. The EPA has adopted rules regulating GHG emissions under the existing CAA, including a rule requiring 
emissions  of  GHGs  from  certain  large  stationary  sources  through  preconstruction  and  operating  permit 
requirements. 

50

6696_10K.pdf

The  EPA  has  also  adopted  rules  requiring  the  reporting  of  GHG  emissions  from  specified  large  GHG 
emission sources in the United States, on an annual basis. Recent regulation of emissions of GHGs has focused on 
fugitive methane emissions. The EPA has also taken steps to limit methane emissions, a GHG, from certain new 
modified  or  reconstructed  facilities  in  the  oil  and  natural  gas  sector  through  the  adoption  of  a  final  rule  in  June 
2016  establishing  Subpart  OOOOa  standards  for  methane  emissions.  However,  in  2017,  the  EPA  published  a 
proposed  rule  to  stay  certain  portions  of  these  Subpart  OOOOa  standards  for  two  years  but  the  rule  was  not 
finalized. Rather, in February 2018, the EPA finalized amendments to certain requirements of the June 2016 final 
rule,  and  in  September  2018  the  EPA  proposed  additional  amendments,  including  rescission  of  certain 
requirements and revisions to other requirements, such as fugitive emission monitoring frequency. In the event that 
the  EPA’s  June  2016  rule  should  remain  or  be  placed  in  effect,  or  should  any  other  new  methane  emission 
standards  be  imposed  on  the  oil  and  natural  gas  sector,  such  requirements  could  result  in  increased  costs  to  our 
operations  as  well  as  result  in  restrictions,  delays  or  cancellations  in  such  operations,  which  costs,  restrictions, 
delays or cancellations could adversely affect our business. 

In  addition,  while  the  United  States  Congress  has  not  taken  any  legislative  action  to  reduce  emissions  of 
GHGs, many states have established GHG cap and trade programs. Most of these cap and trade programs work by 
requiring major sources of emissions, such as electric power plants, or major producers of fuels, such as refineries 
and gas processing plants, to acquire and surrender emission allowances. The number of allowances available for 
purchase is reduced each year in an effort to achieve the overall GHG emission reduction goal. 

Additionally,  the  United  States  is  one  of  almost  200  nations  that,  in  December  2015,  agreed  to  the  Paris 
Agreement,  an  international  climate  change  agreement  in  Paris,  France  that  calls  for  countries  to  set  their  own 
GHG  emissions  targets  and  be  transparent  about  the  measures  each  country  uses  to  achieve  its  GHG  emissions 
targets.  The  Paris  Agreement  entered  into  force  on  November 4,  2016.  However,  in  August  2017,  the  U.S.  State 
Department  officially  informed  the  United  Nations  of  the  intent  of  the  United  States  to  withdraw  from  the  Paris 
Agreement. The Paris Agreement provides for a four-year exit process beginning when it took effect in November 
2016,  which  would  result  in  an  effective  exit  date  of  November  2020.  The  United  States’  adherence  to  the  exit 
process is uncertain and/or the terms on which the United States may reenter the Paris Agreement or a separately 
negotiated agreement are unclear at this time. 

The  adoption  of  legislation  or  regulatory  programs  to  reduce  emissions  of  GHG  could  require  us  to  incur 
increased  operating  costs,  such  as  costs  to  purchase  and  operate  emissions  control  systems,  to  acquire  emissions 
allowances or to comply with new regulatory or reporting requirements. Substantial limitations on GHG emissions 
could  also  adversely  affect  demand  for  the  oil  and  natural  gas  we  produce  and  lowers  the  value  of  our  reserves. 
Consequently, legislation and regulatory programs to reduce emissions of GHG could have an adverse effect on our 
business,  financial  condition  and  results  of  operations.  Additionally,  with  concerns  over  GHG  emissions,  certain 
non-governmental  activists  have  recently  directed  their  efforts  at  advocating  the  shifting  of  funding  away  from 
companies with energy-related assets, which could result in limitations or restrictions on certain sources of funding 
for the energy sector.   

In addition, claims have been made against certain energy companies alleging that GHG emissions from oil 
and natural gas operations constitute a public nuisance under federal and/or state common law. As a result, private 
individuals or public entities may seek to enforce environmental laws and regulations against us and could allege 
personal injury, property damage, or other liabilities. While our business is not a party to any such litigation, we 
could be named in actions making similar allegations. An unfavorable ruling in any such case could significantly 
impact our operations and could have an adverse impact on our financial condition. 

Finally,  some  scientists  have  concluded  that  increasing  concentrations  of  GHG  in  the  Earth’s  atmosphere 
may  produce  climate  changes  that  have  significant  physical  effects,  such  as  increased  frequency  and  severity  of 
storms,  droughts,  floods,  and  other  climatic  events.  Our  offshore  operations  are  particularly  at  risk  from  severe 
climatic  events.  If  any  such  climate  changes  were  to  occur,  they  could  have  an  adverse  effect  on  our  financial 
condition and results of operations. 

The enactment of derivatives legislation could have an adverse effect on our ability to use derivative instruments 
to reduce the effect of commodity price, interest rate and other risks associated with our business. 

The Dodd-Frank Act, enacted on July 21, 2010, expanded federal oversight and regulation of the over-the-
counter derivatives market and entities that participate in that market. The Dodd-Frank Act requires the CFTC and 
the SEC to promulgate rules and regulations implementing the Dodd-Frank Act. Although the CFTC and the SEC 
have finalized certain regulations, others remain to be finalized or implemented and it is not possible at this time to 
predict when this is accomplished.

In  one  of  its  rulemaking  proceedings  still  pending  under  the  Dodd-Frank  Act,  the  CFTC  issued  on 
December 5,  2016,  re-proposed  rules  imposing  position  limits  for  certain  futures  and  option  contracts  in  various 
commodities (including oil and gas) and for swaps that are their economic equivalents. Under the proposed rules on 
position limits, certain types of hedging transactions are exempt from these limits on the size of positions that may 
be held, provided that such hedging transactions satisfy the CFTC’s requirements for certain enumerated “bona fide 
hedging”  transactions  or  positions.  As  these  new  position  limit  rules  are  not  yet  final,  the  impact  of  those 
provisions on us is uncertain at this time. 

The CFTC has designated certain interest rate swaps and credit default swaps for mandatory clearing and the 
associated  rules  also  requires  us,  in  connection  with  covered  derivative  activities,  to  comply  with  clearing  and 
trade-execution requirements or to take steps to qualify for an exemption to such requirements. Although we expect 
to  qualify  for  the  end-user  exception  from  the  mandatory  clearing  requirements  for  swaps  to  be  entered  into  to 
hedge our commercial risks, the application of the mandatory clearing and trade execution requirements to other 
market  participants,  such  as  swap  dealers,  may  change  the  cost  and  availability  of  the  swaps  that  we  use  for 
hedging.  In  addition,  certain  banking  regulators  and  the  CFTC  have  recently  adopted  final  rules  establishing 
minimum margin requirements for uncleared swaps. Although we expect to qualify for, and to utilize, the end-user 
exception  from  such  margin  requirements  for  swaps  to  be  entered  into  to  hedge  our  commercial  risks,  the 
application  of  such  requirements  to  other  market  participants,  such  as  swap  dealers,  may  change  the  cost  and 
availability of the swaps that we use for hedging. If any of our swaps do not qualify for the commercial end-user 
exception,  posting  of  collateral  could  impact  liquidity  and  reduce  cash  available  to  us  for  capital  expenditures, 
therefore reducing our ability to execute hedges to reduce risk and protect cash flows. 

The  full  impact  of  the  Dodd-Frank  Act  and  related  regulatory  requirements  upon  our  business  will  not  be 
known until the regulations are fully implemented and the market for derivatives contracts has adjusted. The Dodd-
Frank Act and any new regulations could significantly increase the cost of derivative contracts, materially alter the 
terms  of  derivative  contracts,  reduce  the  availability  of  derivatives  to  protect  against  risks  we  may  encounter,  or 
reduce our ability to monetize or restructure our existing derivative contracts. If we reduce our use of derivatives as 
a result of the Dodd-Frank Act and regulations implementing the Dodd-Frank Act, our results of operations may 
become more volatile and our cash flows may be less predictable, which could adversely affect our ability to plan 
for and fund capital expenditures. Finally, the Dodd-Frank Act was intended, in part, to reduce the volatility of oil 
and gas prices, which some legislators attributed to speculative trading in derivatives and commodity instruments 
related  to  oil  and  natural  gas.  Our  revenues  could  therefore  be  adversely  affected  if  a  consequence  of  the  Dodd-
Frank Act and implementing regulations is to lower commodity prices. Any of these consequences could have a 
material adverse effect on us, our financial condition and our results of operations. 

In  addition,  the  European  Union  and  other  non-U.S.  jurisdictions  have  implemented  and  continue  to 
implement new regulations with respect to the derivatives market. To the extent we transact with counterparties in 
foreign jurisdictions, we may become directly subject to such regulations and in any event the global derivatives 
market  are  affected  to  the  extent  that  foreign  counterparties  are  affected  by  such  regulations.  At  this  time,  the 
impact of such regulations is not clear.

Hedging transactions may limit our potential gains. 

In order to manage our exposure to price risks in the marketing of our oil, natural gas and natural gas liquids, 
we  periodically  enter  into  oil,  natural  gas  and  natural  gas  liquids  price  hedging  arrangements  with  respect  to  a 
portion  of  our  expected  production.  Our  hedging  policy  provides  that  we  may  enter  into  hedging  arrangements 
covering  up  to  the  following  maximum  percentages  of  volumes:  (i) 90%  of  the  reasonably  anticipated  quarterly 
production  of  oil,  natural  gas  and  natural  gas  liquids  of  proved  developed  producing  (“PDP”)  volumes  during 
months  January  through  July  and  November  through  December,  (ii)  65%  of  the  reasonably  anticipated  quarterly 
production of oil, natural gas and natural gas liquids of PDP volumes during months August through October, (iii) 
50%  of  the  reasonably  anticipated  quarterly  production  of  oil,  natural  gas  and  natural  gas  liquids  of  our  proved 
developed non-producing volumes during months January through July and November through December and (iv) 
0%  of  the  reasonably  anticipated  quarterly  production  of  oil,  natural  gas  and  natural  gas  liquids  of  its  proved 
developed  non-producing  volumes  during  months  August  through  October.  These  arrangements  may  include 
futures contracts on the NYMEX. While intended to reduce the effects of volatile oil and natural gas prices, such 
transactions, depending on the hedging instrument used, may limit our potential gains if oil and natural gas prices 
were to rise substantially over the price established by the hedge. In addition, such transactions may expose us to 
the risk of financial loss in certain circumstances, including instances in which: 

• our production is less than expected or is shut-in for extended periods due to hurricanes or other factors; 

•

•

there is a widening of price differentials between delivery points for our production and the delivery point 
to be assumed in the hedge arrangement; 

the counterparties to our futures contracts fails to perform the contracts; 

• a sudden, unexpected event materially impacts oil or natural gas prices; or 

• we are unable to market our production in a manner contemplated when entering into the hedge contract. 

A majority of our outstanding commodity derivative instruments are with certain lenders or affiliates of the 
lenders  under  our  Bank  Credit  Facility.  Our  derivative  agreements  with  the  lenders  are  secured  by  the  security 
documents  executed  by  the  parties  under  the  Bank  Credit  Facility.  Future  collateral  requirements  for  our 
commodity hedging activities are uncertain and depend on the arrangements we negotiate with the counterparty and 
the volatility of oil and natural gas prices and market conditions. 

We are controlled by Apollo Funds and Riverstone Funds. The interests of Apollo Funds and Riverstone Funds 
may differ from the interests of our other stockholders.

Immediately  following  the  closing  of  the  Stone  Combination,  the  Apollo  Funds  and  Riverstone  Funds 
beneficially  owned  and  possessed  voting  power  over  63%  of  our  common  stock.  Under  the  Stockholders’ 
Agreement,  the  Apollo  Funds  and  the  Riverstone  Funds  may  acquire  additional  shares  of  our  common  stock 
without the approval of our Independent Directors as defined in that certain Stockholders’ Agreement, dated as of 
May 10, 2018 (the “Stockholders’ Agreement”). 

Through their ownership of a majority of our voting power and the provisions set forth in our Amended and 
Restated Certificate of Incorporation, Amended and Restated Bylaws and the Stockholders’ Agreement, the Apollo 
Funds  and  the  Riverstone  Funds  have  the  ability  to  designate  a  majority  of  our  directors  to  be  nominated  for 
election by our stockholders. As a result of the Apollo Funds’ and the Riverstone Funds’ ownership of a majority 
of the voting power of our common stock, we are a “controlled company” as defined in NYSE listing rules and, 
therefore,  we  are  not  subject  to  NYSE  requirements  that  would  otherwise  require  us  to  have  a  majority  of 
independent directors and nominating and compensation committees composed solely of independent directors. We 
have not elected to take advantage of the “controlled company” exemptions available to us, but we may do so in the 
future. 

The  Apollo  Funds  and  the  Riverstone  Funds  also  have  control  over  all  other  matters  submitted  to 
stockholders for approval, including changes in capital structure, transactions requiring stockholder approval under 
Delaware  law,  and  corporate  governance,  subject  to  the  terms  of  the  Stockholders’  Agreement  that  require  the 
Apollo Funds and the Riverstone Funds to vote in a specified manner on certain actions, including their agreement 
to vote in favor of director nominees not designated by the Apollo Funds and the Riverstone Funds. The Apollo 
Funds  and  the  Riverstone  Funds  may  have  different  interests  than  other  holders  of  our  common  stock  and  may 
make decisions adverse to your interests.

53

6696_10K.pdf

Among other things, the Apollo Funds’ and Riverstone Funds’ control could delay, defer or prevent a sale of 
us  that  our  other  stockholders  support,  or,  conversely,  this  control  could  result  in  the  consummation  of  such  a 
transaction that other stockholders do not support. This concentrated control could discourage a potential investor 
from seeking to acquire our common stock and, as a result, might harm the market price of our common stock.

If securities or industry analysts do not publish research or reports about our business, if they adversely change 
their recommendations regarding our common stock, or if our operating results do not meet their expectations, 
the price of our common stock could decline.

The  trading  market  for  our  common  stock  will  be  influenced  by  the  research  and  reports  that  industry  or 
securities analysts publish about us or our business. If one or more of these analysts cease coverage of us or fail to 
publish  reports  on  us  regularly,  we  could  lose  visibility  in  the  financial  markets,  which  in  turn  could  cause  our 
stock price or trading volume to decline. Moreover, if one or more of the analysts who cover us downgrades our 
common stock or if our operating results do not meet their expectations, our stock price could decline.

Negative publicity may adversely impact us.

Media  coverage  and  public  statements  that  insinuate  improper  actions  by  us,  regardless  of  their  factual 
accuracy or truthfulness, may result in negative publicity, litigation or governmental investigations by regulators. 
Addressing  negative  publicity  and  any  resulting  litigation  or  investigations  may  distract  management,  increase 
costs and divert resources. Negative publicity may have an adverse impact on our reputation and the morale of our 
employees,  which  could  materially  adversely  affect  our  business,  financial  position,  results  of  operations,  cash 
flows, growth prospects and stock price. 

The  corporate  opportunity  provisions  in  our  Amended  and  Restated  Certificate  of  Incorporation  could  enable 
others to benefit from corporate opportunities that might otherwise be available to us.

Subject to the limitations of applicable law, our Amended and Restated Certificate of Incorporation, among 

other things:

• permits  us  to  enter  into  transactions  with  entities  in  which  one  or  more  of  our  officers  or  directors  are 

financially or otherwise interested;

• permits the Apollo Funds, the Riverstone Funds, and any of our officers or directors who is also an officer, 
director, employee, managing director, or other affiliate of the Apollo Funds or the Riverstone Funds to conduct 
business  that  competes  with  us  and  to  make  investments  in  any  kind  of  property  in  which  we  may  make 
investments; and

• provides that if the Apollo Funds, the Riverstone Funds, or any of our officers or directors who is also an 
officer,  director,  employee,  managing  director  or  other  affiliate  of  the  Apollo  Funds  or  the  Riverstone  Funds 
becomes aware of a potential business opportunity, transaction or other matter (other than one expressly offered to 
that director or officer in writing solely in his or her capacity as an director or officer of us), that director or officer 
will have no duty to communicate or offer that opportunity to us, and will be permitted to communicate or offer 
that opportunity to any other entity or individual and that director or officer will not be deemed to have acted in a 
manner inconsistent with his or her fiduciary duty to us or our stockholders.

These provisions create the possibility that a corporate opportunity that would otherwise be available to us 

may be used for the benefit of others. 

Our  Amended  and  Restated  Certificate  of  Incorporation  designates  the  Court  of  Chancery  of  the  State  of 
Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by 
our  stockholders,  which  could  limit  our  stockholders’  ability  to  obtain  a  favorable  judicial  forum  for  disputes 
with us or our directors, officers, employees or agents.

Our  Amended  and  Restated  Certificate  of  Incorporation  provides  that,  unless  we  consent  in  writing  to  the 
selection  of  an  alternative  forum,  the  Court  of  Chancery  of  the  State  of  Delaware  will  be  the  sole  and  exclusive 
forum for (i) any derivative action or proceeding brought on behalf of us, (ii) any action asserting a claim of breach 
of  a  fiduciary  duty  owed  by  any  of  our  current  or  former  directors,  officers,  employees,  agents  or  stockholders 
(including a beneficial owner of stock) to us or our stockholders, (iii) any action asserting a claim arising pursuant 
to any provision of the Delaware General Corporation Law, our Amended and Restated Certificate of Incorporation 
or Amended and Restated Bylaws, or (iv) any action asserting a claim governed by the internal affairs doctrine, in 
each  case  subject  to  the  Court  of  Chancery  having  personal  jurisdiction  over  the  indispensable  parties  named  as 

54

6696_10K.pdf

defendants  in  the  case.  Any  person  or  entity  purchasing  or  otherwise  acquiring  any  interest  in  any  share  of  our 
capital  stock  will  be  deemed  to  have  notice  of  and  consent  to  these  provisions  of  our  Amended  and  Restated 
Certificate of Incorporation. This exclusive forum provision may limit a stockholder’s ability to bring a claim in a 
judicial forum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may 
discourage such lawsuits against us and such persons. Alternatively, if a court were to find these provisions of our 
Amended and Restated Certificate of Incorporation inapplicable to, or unenforceable in respect of, one or more of 
the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters 
in other jurisdictions, which could adversely affect our business, financial condition or results of operations.

The Apollo Funds and the Riverstone Funds are prohibited from transferring a portion of their shares of our 
common  stock  until  the  first  anniversary  of  the  Closing  Date,  after  which,  subject  to  restrictions,  they  will  be 
permitted to transfer their shares of our common stock, which could have a negative impact on our stock price.

Pursuant to the Stockholders’ Agreement, and unless approved by a majority of our Independent Directors 
(as defined in the Stockholders’ Agreement), the Apollo Funds and the Riverstone Funds will be restricted from 
transferring,  other  than  to  an  affiliate,  25%  of  the  respective  shares  of  our  common  stock  held  by  each  on  the 
Closing  Date,  until  May  10,  2019.  Beginning  on  May  10,  2019,  the  lock-up  will  cease  to  apply  and  the  Apollo 
Funds  and  the  Riverstone  Funds  will  be  permitted,  subject  to  certain  restrictions,  to  transfer  such  shares  of  our 
common stock, including in public offerings pursuant to registration rights granted by us. Any such transfer could 
significantly  increase  the  number  of  shares  of  our  common  stock  available  in  the  market,  which  could  cause  a 
decrease in the price of our common stock. 

Additionally, pursuant to the Stockholders’ Agreement, until the first anniversary of the Closing Date, each 
of the Apollo Funds and the Riverstone Funds will be prohibited from transferring any shares of our common stock 
in  any  transaction  that  would  result  in  the  transferee  owning  more  than  35%  of  the  outstanding  shares  of  our 
common stock without the prior approval of a majority of our Independent Directors, unless such transferee agrees 
in  writing  to  be  bound  by  substantially  the  same  provisions  as  the  stockholders  are  bound  by  pursuant  to  the 
Stockholders’ Agreement. Following the first anniversary of the Closing Date, the Apollo Funds and the Riverstone 
Funds  could  sell  a  significant  percentage  of  our  common  stock  to  a  third  party  that  is  not  subject  to  provisions 
similar to the provisions in the Stockholders’ Agreement. 

A change in the jurisdictional characterization of our FERC-jurisdictional pipelines, tribal or local regulatory 
agencies or a change in policy by those agencies may result in increased regulation of such asset, which may 
cause  our  revenues  to  decline  and  operating  expenses  to  increase  or  delay  or  increase  the  cost  of  expansion 
projects.

SP 49 Pipeline LLC is considered a common carrier pipeline subject to regulation by FERC under ICA. The 
ICA requires that we maintain a tariff on file with FERC for SP 49 Pipeline LLC that sets forth the rates we charge 
for providing transportation service as well as the rules and regulations governing such service. The ICA requires, 
among other things, that the rates, terms and conditions of service on interstate common carrier pipelines be “just 
and reasonable” and non-discriminatory.  In the event a shipper protests the rates, terms or conditions of service in 
effect pursuant to the tariff, we may be required to modify such rates, terms, or conditions, which could adversely 
affect  the  results  of  our  operations.    With  respect  to  CKB  Petroleum,  Inc.,  which  has  been  granted  a  waiver  of 
certain portions of the ICA and related regulations by FERC, should the pipeline’s circumstances change, FERC 
could, either at the request of other entities or on its own initiative, assert that such pipeline no longer qualifies for a 
waiver. In the event that FERC were to determine that CKB Petroleum, Inc. no longer qualified for a waiver, we 
would likely be required to file a tariff with FERC, provide a cost justification for the transportation charge, and 
provide service to all potential shippers without undue discrimination. Such a change in the jurisdictional status of 
transportation on the CKB Pipeline could adversely affect our results of operations.

Item 3. Legal Proceedings

We  are  named  as  a  party  in  certain  lawsuits  and  regulatory  proceedings  arising  in  the  ordinary  course  of 
business. We do not expect that these matters, individually or in the aggregate, will have a material adverse effect 
on our financial condition. 

On  January  6,  2016,  ERT  plead  guilty  to  two  violations  of  the  Clean  Water  for  self-reported  activities 
surrounding overboard discharge sampling and unpermitted discharges and two violations of OSCLA. On April 6, 
2016,  the  United  States  District  Court  for  the  Eastern  District  of  Louisiana  accepted  ERT’s  plea  and  sentenced 
ERT, consistent with the plea agreement, to pay a penalty of $4.2 million which ERT has paid. The Court placed 
ERT  on  probation  for  three  years.  The  conditions  of  probation  include  compliance  with  an  agreed  Safety  and 
Environmental  Compliance  Program.  As  a  result  of  ERT’s  conviction  for  violations  of  the  CWA,  ERT  was 
debarred  and  cannot  enter  into  contracts  with  or  receive  benefits  from  the  federal  government,  until  the  EPA 
reinstates ERT by certifying that ERT has corrected the conditions giving rise to the Clean Water convictions. EPA 
also imposed discretionary suspension and proposed debarment on Talos Production LLC, Talos Energy Offshore 
LLC  and  Talos  Energy  LLC  as  affiliates  of  ERT.  On  November  23,  2016,  EPA  terminated  and  administratively 
closed the suspension as to each of the three entities previously suspended. On August 29, 2017, EPA certified that 
the conditions giving rise to ERT’s conviction were corrected, and its debarment was lifted.  

The  following  proceedings  represent  previous  Stone  litigation  that  was  assumed  as  part  of  the  Stone 

Combination. 

On  November 17,  2014,  the  Pennsylvania  Department  of  Environmental  Protection  (“PADEP”)  issued  a 
Notice  of  Violation  (“NOV”)  to  Stone  alleging  releases  of  production  fluid  and  an  improper  closure  of  a  drill 
cuttings  pit  at  Stone’s  Loomis  No. 1  well  site  in  Susquehanna  County,  Pennsylvania.  Prior  to  this,  in  September 
2014,  Stone  had  transferred  ownership  of  the  Loomis  No. 1  well  site  to  Southwestern  Energy  Company 
(“Southwestern”).  PADEP  approved  the  transfer  on  November 24,  2014,  after  issuing  the  NOV  to  Stone.  Stone 
investigated the allegations found in the NOV and responded to PADEP on January 5, 2015. Reclamation of the 
site by Southwestern, with the participation of the PADEP and Stone, was completed. The PADEP may impose a 
penalty in this matter, but the amount of such penalty cannot be reasonably estimated at this time. 

On  November 11,  2013,  two  lawsuits  were  filed,  and  on  November 12,  2013,  a  third  lawsuit  was  filed, 
against Stone and other named co-defendants, by the Parish of Jefferson (“Jefferson Parish”), on behalf of Jefferson 
Parish and the State of Louisiana, in the 24th Judicial District Court for the Parish of Jefferson, State of Louisiana, 
alleging  violations  of  the  State  and  Local  Coastal  Resources  Management  Act  of  1978,  as  amended,  and  the 
applicable  regulations,  rules,  orders  and  ordinances  thereunder  (collectively,  the  “CRMA”),  relating  to  certain  of 
the  defendants’  alleged  oil  and  gas  operations  in  Jefferson  Parish,  and  seeking  to  recover  alleged  unspecified 
damages  to  the  Jefferson  Parish  Coastal  Zone  and  remedies,  including  unspecified  monetary  damages  and 
declaratory relief, restoration of the Jefferson Parish Coastal Zone and related costs and attorney’s fees. In March 
and April 2016, the Louisiana Attorney General and the Louisiana Department of Natural Resources, respectively, 
intervened  in  the  three  lawsuits.  In  connection  with  Stone’s  filing  of  bankruptcy  in  December  2016,  Jefferson 
Parish dismissed its claims against Stone in two of the three Jefferson Parish Coastal Zone Management lawsuits 
without  prejudice  to  refiling;  the  claims  of  the  Louisiana  Attorney  General  and  the  Louisiana  Department  of 
Natural  Resources  were  not  similarly  dismissed.  The  Jefferson  Parish  lawsuits  have  been  removed  to  the  United 
States District Court for the Eastern District of Louisiana. The plaintiffs have moved to remand the lawsuit to the 
state courts. 

On  November 8,  2013,  a  lawsuit  was  filed  against  Stone  and  other  named  co-defendants  by  the  Parish  of 
Plaquemines  (“Plaquemines  Parish”),  on  behalf  of  Plaquemines  Parish  and  the  State  of  Louisiana,  in  the  25th 
Judicial District Court for the Parish of Plaquemines, State of Louisiana, alleging violations of the CRMA, relating 
to certain of the defendants’ alleged oil and gas operations in Plaquemines Parish, and seeking to recover alleged 
unspecified  damages  to  the  Plaquemines  Parish  Coastal  Zone  and  remedies,  including  unspecified  monetary 
damages  and  declaratory  relief,  restoration  of  the  Plaquemines  Parish  Coastal  Zone,  and  related  costs  and 
attorney’s fees. In March and April 2016, the Louisiana Attorney General and the Louisiana Department of Natural 
Resources,  respectively,  intervened  in  the  lawsuit.  In  connection  with  Stone’s  filing  of  bankruptcy  in  December 
2016,  Plaquemines  Parish  dismissed  its  claims  against  Stone  without  prejudice  to  refiling;  the  claims  of  the 
Louisiana Attorney General and the Louisiana Department of Natural Resources were not similarly dismissed. The 
Plaquemines  Parish  lawsuit  has  been  stayed  pending  the  conclusion  of  trials  in  five  other  cases,  also  filed  in 
Plaquemines Parish and alleging violations of the CRMA, but not involving Stone. The Plaquemines Parish lawsuit

The  following  table  sets  forth  our  selected  consolidated  historical  financial  data  as  of  and  for  the  periods 
ended  on  the  dates  indicated  below.  The  selected  historical  statement  of  operations  data  for  the  years  ended 
December 31,  2018,  2017  and  2016  and  the  selected  historical  balance  sheet  data  as  of  December 31,  2018  and 
2017, have been derived from our audited consolidated financial statements and related notes for the year ended 
December 31,  2018,  which  are  included  elsewhere  in  this  report.  The  selected  historical  statement  of  operations 
data  for  the  years  ended  December 31,  2015  and  2014,  and  the  selected  historical  balance  sheet  data  as  of 
December 31, 2016, 2015 and 2014 have been derived from our audited consolidated financial statements, which 
have not been included in this report. Our consolidated financial statements have been prepared in accordance with 
GAAP.  Our  results  of  operations  in  any  period  may  not  necessarily  be  indicative  of  the  results  that  may  be 
expected for any future period. See Part I, Item 1A. Risk Factors for additional information.

As previously described, Stone and Talos Energy became our wholly-owned subsidiaries on the Closing Date 
in  connection  with  the  Stone  Combination.  Prior  to  the  Closing  Date,  Talos  Energy  Inc.  had  not  conducted  any 
material activities other than those incident to its incorporation and certain matters contemplated by the Transaction 
Agreement. Talos Energy is the acquirer of Stone for financial reporting and accounting purposes. Talos Energy 
was considered the accounting acquirer in the Transactions under GAAP. Accordingly, the selected consolidated 
historical financial data presented in the tables below, which covers periods prior to the Closing Date, reflects the 
assets, liabilities and operations of Talos Energy prior to the Closing Date and does not reflect the assets, liabilities 
and  operations  of  Stone  prior  to  the  Closing  Date.  In  addition,  we  incurred  material  costs  associated  with  the 
Transactions that are reflected in our historical results of operations for periods prior to the Closing Date, and Talos 
Energy did not incur United States federal income tax expense or the incremental expense associated with being a 
public company. 

The  selected  consolidated  historical  financial  information  should  be  read  in  conjunction  with  our  financial 
statements  and  the  related  notes  included  elsewhere  in  this  report,  as  well  as  Part  II,  Item  7.  Management’s

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Our Business 

We are a technically driven independent exploration and production company with operations in the United 
States Gulf of Mexico and offshore Mexico. Our focus in the United States Gulf of Mexico is the acquisition of 
deepwater  assets  with  existing  infrastructure  and  the  exploration,  exploitation  and  development  of  such  assets  in 
key geologic trends. Offshore Mexico provides us high impact exploration opportunities in an emerging basin. We 
use  our  access  to  an  extensive  seismic  database  and  our  deep  technical  expertise  to  identify,  acquire  and  exploit 
attractive assets with robust economic profiles. Our management and technical teams have a long history working 
together and have made significant discoveries in the deep waters of the Gulf of Mexico and offshore Mexico. 

On  the  Closing  Date,  we  acquired  Stone,  an  independent  oil  and  natural  gas  company  engaged  in  the 
acquisition,  exploration,  exploitation,  development  and  operation  of  oil  and  gas  properties.  The  Stone  properties 
acquired  in  the  Stone  Combination  are  located  primarily  in  the  deep  water  of  the  Gulf  of  Mexico,  with  limited 
exposure  to  Gulf  of  Mexico  conventional  shelf  and  deep  gas  properties.  As  of  the  closing  of  the  Stone 
Combination, Stone’s property portfolio consisted primarily of nine active properties and 34 primary term leases in 
the  Gulf  of  Mexico  Basin.  For  more  information  on  the  Stone  Combination,  please  read  Part  I,  Item  1  and  2. 
Business and Properties.

In order to determine the most attractive returns for our drilling program, we employ a disciplined portfolio 
management  approach  to  stochastically  evaluate  all  of  our  drilling  prospects,  whether  they  are  generated 
organically from our existing acreage or are acquisition or joint venture opportunities. We add to and reevaluate 
our inventory in order to deploy our capital as efficiently as possible. 

We  plan  to  opportunistically  expand  our  asset  base  by  evaluating  the  robust  supply  of  acquisition 
opportunities in the Gulf of Mexico. The acquisition strategy is focused on deep and shallow water assets with a 
geological  setting  which  we  believe  can  benefit  from  our  access  to  an  extensive  seismic  database  and  our 
reprocessing  expertise  to  reevaluate  the  acquired  assets.  We  expect  to  target  acquisitions  involving  assets  with 
physical  infrastructure  that  will  allow  us  to  focus  on  additional  drilling  opportunities.  By  applying  a  disciplined 
valuation  methodology,  we  seek  to  reduce  the  risk  of  acquired  property  underperformance  while  maintaining 
potential  for  higher  returns  on  our  investment.  In  addition,  we  may  consider  acquisition  opportunities  in  other 
offshore basins with analogous geologies that are suitable for our operational and technical expertise to the extent 
we believe it will increase our reserves and enhance returns on our investment and long-term growth prospects. 

Recent Developments 

In the fourth quarter of 2018, we spud the Zama-2 well, the first appraisal well to be drilled in the field. The 
Zama-2  well  confirmed  the  results  of  the  original  Zama-1  exploration  well.  The  Zama  appraisal  campaign  is 
expected to be completed by approximately mid-year 2019. If the appraisal of the Zama field confirms our initial 
estimates, we expect to announce a Final Investment Decision in 2020, following Mexican government approval of 
the development plan. In addition to Zama, other prospects are being analyzed and matured to potentially be drilled 
over the next several years.

In September 2018, we entered into a transaction the Hokchi Cross Assignment with Hokchi, to cross assign 
25% PIs in Block 2 and Block 31. Our assignment of a 25% PI in Block 2 to Hokchi closed on December 21, 2018, 
and Hokchi has assumed operator responsibilities with respect to Block 2. Hokchi’s assignment of Block 31 to us 
will be completed upon final approval by the CNH, Mexico’s upstream regulator. In addition, Premier exercised its 
option  to  reduce  its  PI  in  Block  2  to  zero  and  assign  a  5%  PI  to  each  of  Sierra  and  us.  Such  assignment  is  also 
subject to CNH’s approval. Upon completion of the Hokchi Cross Assignment and Premier’s option exercise, we 
will own a 25% PI in each of Block 2 and Block 31, and Hokchi will be the operator of both blocks.

In February 2019, CHN granted approval for drilling in the Acan prospect in Block 2. Hokchi intends to start 
drilling  in  March  2019.  Soon  thereafter,  we  plan  to  participate  in  two  prospects  in  Block  31.  Beyond  the  Acan 
prospects,  we  believe  that  Blocks  2  and  31  contain  a  significant  portfolio  of  compelling  prospects  with  strong 
technical ties to offsetting discoveries.

Factors Affecting the Comparability of our Financial Condition and Results of Operations 

Stone Combination 

As  previously  described,  Stone  and  Talos  Energy  became  our  wholly-owned  subsidiaries  on  the  Closing 
Date.  Prior  to  the  Closing  Date,  Talos  Energy  Inc.  had  not  conducted  any  material  activities  other  than  those 
incident to its incorporation and certain matters contemplated by the Transaction Agreement. Talos Energy is the 
acquirer  of  Stone  for  financial  reporting  and  accounting  purposes  and  considered  the  accounting  acquirer  in  the 
Transactions under GAAP. Accordingly, our historical financial and operating data, which covers periods prior to 
the Closing Date, reflects the assets, liabilities and results of operations of Talos Energy prior to the Closing Date 
and does not reflect the assets, liabilities and results of operations of Stone prior to the Closing Date. See Part II, 
Item 8. Financial Statements and Supplementary Data — Note 3 — Acquisitions for more information. 

Whistler Acquisition

On August 31, 2018, we completed the acquisition of all the issued and outstanding membership interests of 
Whistler  from  Whistler  Energy  II  Holdco,  LLC  for  $52.6 million  ($14.8 million  net  of  $37.8 million  of  cash 
acquired). See Part II, Item 8. Financial Statements and Supplementary Data — Note 3 — Acquisitions for more 
information. 

Sojitz Acquisition

On December 20, 2016, we purchased an additional 15% working interest in the Phoenix Field from Sojitz 
Energy  Venture,  Inc.  for  approximately  $85.8 million  in  cash  and  the  assumption  of  certain  asset  retirement 
obligations,  subject  to  customary  post-closing  adjustments.  The  purchase  price  was  funded  by  a  $93.8 million 
($91.9 million,  net  of  $1.9 million  of  transaction  fees)  contribution  from  the  Sponsors.  Additionally,  we  entered 
into  a  contingent  consideration  arrangement  in  the  form  of  an  earn-out  equal  to  5%  of  the  acquired  property’s 
monthly net profit if our realized oil price is greater than $65.00 per Bbl in a given month. The maximum payout 
under the earn-out is $10.0 million and has an indefinite life pursuant to the purchase and sale agreement. See Part 
II, Item 8. Financial Statements and Supplementary Data — Note 3 — Acquisitions for more information.

Transaction Expenses 

We  have  incurred  and  will  continue  to  incur  transaction  related  and  restructuring  costs  associated  with  the 
Stone  Combination  and  the  integration  of  the  businesses  of  Stone  and  Talos  Energy  that  are  not  reflected  in  our 
comparative historical results of operations. 

Income Tax Expenses 

Prior to the Stone Combination, Talos Energy LLC was a partnership for U.S. federal income tax purposes 
and  was  not  subject  to  U.S.  federal  income  tax  or  state  income  tax  (in  most  states)  at  the  entity  level.  As  such, 
Talos Energy LLC did not recognize U.S. federal income tax expense or state income tax expense in most states. 
Talos  Energy  LLC’s  operations  in  the  shallow  waters  off  the  coast  of  Mexico  were  conducted  under  a  different 
legal form and are subject to foreign income taxes. 

In  connection  with  the  Stone  Combination,  Talos  Energy  LLC  was  contributed  to  us.  We  are  subject  to 
federal and state income taxes. We record current income taxes based on estimates of current taxable income and 
provide for deferred income taxes to reflect estimated future income tax payments and receipts.

Third Party Planned Downtime 

Since  our  operations  are  offshore,  we  are  vulnerable  to  third  party  downtime  events  impacting  the 
transportation,  gathering  or  processing  of  production.  We  produce  the  Phoenix  Field  through  the  HP-I  that  is 
operated by Helix. Helix is required to disconnect and dry-dock the HP-I every two to three years for inspection as 
required  by  the  United  States  Coast  Guard,  during  which  time  we  are  unable  to  produce  the  Phoenix  Field.  In 
January 2019, Helix dry-docked the HP-I for inspection and the shut-in is expected to last until March 2019. For 
the  year  ended  December 31,  2018,  the  Phoenix  Field  produced  17.9  MBoepd.  The  impact  of  the  shut-in  on  the 
first quarter of 2019 production is estimated to be between 9.0 MBoepd and 13.0 MBoepd, whereas the annualized 
impact for full year 2019 is expected to be between 2.0 MBoepd and 3.0 MBoepd. In the current commodity price 
environment, the shut-in represents an estimated cash flow impact of $35.0 million to $55.0 million, primarily in 
the first quarter of 2019.

6696_10K.pdf

Known Trends and Uncertainties 

Volatility  in  Oil,  Natural  Gas  and  NGL  Prices.  Historically,  the  markets  for  oil  and  natural  gas  have  been 
volatile. Our revenue, profitability, access to capital and future rate of growth depends upon the price we receive 
for  our  sales  of  oil,  natural  gas  and  NGL  production.  Oil,  natural  gas  and  NGL  prices  are  subject  to  wide 
fluctuations in response to relatively minor changes in supply and demand. 

BOEM Bonding Requirements. In order to cover the various decommissioning obligations of lessees on the 
OCS,  BOEM  generally  requires  that  lessees  post  some  form  of  acceptable  financial  assurances  that  such 
obligations  will  be  met,  such  as  surety  bonds.  The  cost  of  such  bonds  or  other  financial  assurance  can  be 
substantial, and we can provide no assurance that we can continue to obtain bonds or other surety in all cases. As 
many BOEM regulations are being reviewed by the agency, we may be subject to additional financial assurance 
requirements  in  the  future.  For  example,  in  July  2016,  BOEM  issued  the  NTL  2016-N01  (“the  2016  NTL”)  to 
clarify  the  procedures  and  guidelines  that  BOEM  Regional  Directors  use  to  determine  if  and  when  additional 
financial  assurances  may  be  required  for  OCS  leases,  ROWs  and  RUEs.  The  2016  NTL  became  effective  in 
September 2016, but BOEM subsequently postponed any implementation of the 2016 NTL and has indicated they 
will  be  issuing  a  modified  or  substitute  NTL.  This  extension  for  implementation  currently  remains  in  effect.  We 
remain in active discussions with government regulators and industry peers with regard to any future rulemaking 
and financial assurance requirements. Notwithstanding BOEM’s 2016 NTL, BOEM may also bolster its financial 
assurance  requirements  mandated  by  rule  for  all  companies  operating  in  federal  waters.  The  future  cost  of 
compliance with respect to supplemental bonding, including the obligations imposed on us as a result of the 2016 
NTL, to the extent implemented, as well as any other future BOEM directives, or any other changes to BOEM’s 
rules  applicable  to  our  or  any  of  our  subsidiaries’  properties,  could  materially  and  adversely  affect  our  financial 
condition, cash flows and results of operations. 

Deepwater  Operations.  We  have  interests  in  deepwater  fields  in  the  Gulf  of  Mexico.  Operations  in  the 
deepwater can result in increased operational risks as has been demonstrated by the Deepwater Horizon disaster in 
2010.  Despite  technological  advances  since  this  disaster,  liabilities  for  environmental  losses,  personal  injury  and 
loss of life and significant regulatory fines in the event of a disaster could be well in excess of insured amounts and 
result in significant current losses on our statements of operations as well as going concern issues. 

Oil  Spill  Response  Plan.  We  maintain  a  Regional  Oil  Spill  Response  Plan  that  defines  our  response 
requirements,  procedures  and  remediation  plans  in  the  event  we  have  an  oil  spill.  Oil  Spill  Response  Plans  are 
generally  approved  by  BSEE  bi-annually,  except  when  changes  are  required,  in  which  case  revised  plans  are 
required to be submitted for approval at the time changes are made. Additionally, these plans are tested and drills 
are conducted periodically at all levels. 

Hurricanes. Since our operations are in the Gulf of Mexico, we are particularly vulnerable to the effects of 
hurricanes  on  production.  Additionally,  affordable  insurance  coverage  for  property  damage  to  our  facilities  for 
hurricanes has become less effective due to rising retentions and limitations on named windstorm coverage and has 
been  difficult  to  obtain  at  times  in  recent  years.  Significant  hurricane  impacts  could  include  reductions  and/or 
deferrals of future oil and natural gas production and revenues, increased lease operating expenses for evacuations 
and repairs and possible acceleration of P&A costs. 

How We Evaluate Our Operations 

We  use  a  variety  of  financial  and  operational  metrics  to  assess  the  performance  of  our  oil  and  natural  gas 

operations, including: 

• production volumes; 

•

•

realized prices on the sale of oil, natural gas and NGLs, including the effect of our commodity derivative 
contracts; 

lease operating expenses; 

• capital expenditures; and 

• Adjusted EBITDA, which is discussed under—Supplemental Non-GAAP Measure.

Basis of Presentation 

Sources of Revenues 

Our revenues are derived from the sale of our oil and natural gas production, as well as the sale of NGLs that 
are  extracted  from  our  natural  gas  during  processing.  Our  oil,  natural  gas  and  NGL  revenues  do  not  include  the 
effects of derivatives, which are reported in price risk management activities income in our consolidated statements 
of operations. The following table presents a breakout of each revenue component:

Our revenues may vary significantly from period to period as a result of changes in volumes of production 

sold or changes in commodity prices. 

Realized Prices on the Sale of Oil, Natural Gas and NGLs. The NYMEX WTI prompt month oil settlement 
price is a widely used benchmark in the pricing of domestic oil in the United States. The actual prices we realize 
from the sale of oil differ from the quoted NYMEX WTI price as a result of quality and location differentials. For 
example, the prices we realize on the oil we produce are affected by the Gulf of Mexico Basin’s proximity to U.S. 
Gulf  Coast  refineries  and  the  quality  of  the  oil  production  sold  in  Eugene  Island  Crude,  Louisiana  Light  Sweet 
Crude and Heavy Louisiana Sweet Crude markets. 

The NYMEX Henry Hub price of natural gas is a widely used benchmark for the pricing of natural gas in the 
United  States.  Similar  to  oil,  the  actual  prices  we  realize  from  the  sale  of  natural  gas  differ  from  the  quoted 
NYMEX  Henry  Hub  price  as  a  result  of  quality  and  location  differentials.  Currently,  the  sales  points  of  our  gas 
production are generally within close proximity to the Henry Hub which creates a minimal differential in the prices 
we receive for our production versus average Henry Hub prices. 

In the past, oil and natural gas prices have been extremely volatile, and we expect this volatility to continue, 
as indicated in the table below, which provides the high, low and average prices for NYMEX WTI and NYMEX 
Henry Hub monthly contract prices as well as our average realized oil and natural gas sales prices for the periods 
indicated.

To achieve more predictable cash flow, and to reduce exposure to adverse fluctuations in commodity prices, 
from time to time we enter into commodity derivative arrangements for our anticipated production. By removing a 
significant portion of price volatility associated with our anticipated production, we believe it will mitigate, but not 
eliminate, the potential negative effects of reductions in oil and natural gas prices on our cash flow from operations 
for  those  periods.  However,  in  a  portion  of  our  current  positions,  our  price  risk  management  activity  may  also 
reduce  our  ability  to  benefit  from  increases  in  prices.  We  will  sustain  losses  to  the  extent  our  commodity 
derivatives  contract  prices  are  lower  than  market  prices  and,  conversely,  we  will  sustain  gains  to  the  extent  our 
commodity derivatives contract prices are higher than market prices. 

We will continue to use commodity derivative instruments to manage commodity price risk in the future. Our 
hedging  strategy  and  future  hedging  transactions  will  be  determined  at  our  discretion  and  may  be  different  from 
what we have done on a historical basis. 

Expenses 

Direct lease operating expense. Direct lease operating expense consists of the daily costs incurred to bring 
oil,  natural  gas  and  NGLs  out  of  the  underground  formation  and  to  the  market,  together  with  the  daily  costs 
incurred to maintain our producing properties. Expenses for direct labor, HP-I lease, materials and supplies, rental 
and third party costs comprise the most significant portion of our direct lease operating expense. In July 2016, we 
executed a new contract for the HP-I accounted for as a capital lease, thus reducing the amount recorded as direct 
lease operating expenses going forward. 

Insurance expense. Insurance expense consists of the cost of insurance policies to cover some of our risk of 
loss associated with our operations, and we maintain the amount of insurance we believe is prudent based on our 
estimated  loss  potential.  Our  significant  domestic  and  international  policies  include  general  liability,  physical 
damage  to  our  oil  and  gas  properties,  operational  control  of  well,  named  Gulf  of  Mexico  windstorm  and  oil 
pollution. 

Production  taxes.  Production  taxes  consist  of  severance  taxes  levied  by  the  Louisiana  Department  of 
Revenue  on  production  of  oil  and  natural  gas  from  land  or  water  bottoms  within  the  boundaries  of  the  state  of 
Louisiana. 

Workover  and  maintenance  expense.  Workover  and  maintenance  expense  consists  of  costs  associated  with 
major remedial operations on completed wells to restore, maintain or improve the well’s production. Because the 
amount of workover and maintenance expense is closely correlated to the levels of workover activity, which is not 
regularly scheduled, workover and maintenance expense is not necessarily comparable from period to period. 

Depreciation,  depletion  and  amortization  expense.  Depreciation,  depletion  and  amortization  expense  is  the 
expensing of the capitalized costs incurred to acquire, explore and develop oil and natural gas reserves. We use the 
full  cost  method  of  accounting  for  oil  and  natural  gas  activities.  See  Part  II,  Item  8.  Financial  Statements  and 
Supplementary Data — Note 2 — Summary of Significant Accounting Policies for further discussion. 

Accretion expense. We have obligations associated with the retirement of our oil and natural gas wells and 
related infrastructure. We have obligations to plug wells when production on those wells is exhausted, when we no 
longer plan to use them or when we abandon them. We accrue a liability with respect to these obligations based on 
our estimate of the timing and amount to replace, remove or retire the associated assets. Accretion of the liability is 
recognized for changes in the value of the liability as a result of the passage of time over the estimated productive 
life of the related assets as the discounted liabilities are accreted to their expected settlement values. 

General and administrative expense. General and administrative expense generally consists of costs incurred 
for overhead, including payroll and benefits for our corporate staff, costs of maintaining our headquarters, costs of 
managing our production operations, bad debt expense, equity based compensation expense, audit and other fees 
for professional services and legal compliance. 

Interest  expense.  We  finance  a  portion  of  our  working  capital  requirements,  capital  expenditures  and 
acquisitions  with  borrowings  under  our  Bank  Credit  Facility  and  term  based  debt.  As  a  result,  we  incur  interest 
expense that is affected by both fluctuations in interest rates and our financing decisions. Interest includes interest 
incurred  under  our  debt  agreements,  the  amortization  of  deferred  financing  costs  (including  origination  and 
amendment fees), commitment fees, imputed interest on our capital lease, performance bond premiums and annual 
agency  fees.  Interest  expense  is  net  of  capitalized  interest  on  expenditures  made  in  connection  with  exploratory 
projects that are not subject to current amortization.

Price  risk  management  activities.  We  utilize  commodity  derivative  instruments  to  reduce  our  exposure  to 
fluctuations in the price of oil and natural gas. We recognize gains and losses associated with our open commodity 
derivative  contracts  as  commodity  prices  and  the  associated  fair  value  of  our  commodity  derivative  contracts 
change.  The  commodity  derivative  contracts  we  have  in  place  are  not  designated  as  hedges  for  accounting 
purposes. Consequently, these commodity derivative contracts are marked-to-market each quarter with fair value 
gains and losses recognized currently as a gain or loss in our results of operations. Cash flow is only impacted to 
the extent the actual settlements under the contracts result in making a payment to or receiving a payment from the 
counterparty.

Revenue.  Total  revenue  for  the  year  ended  December 31,  2018  was  $891.3  million  compared  to  $412.8 

million for the year ended December 31, 2017, an increase of approximately $478.5 million or 116%. 

Oil revenue increased by approximately $437.0 million, or 127%, during the year ended December 31, 2018 
compared to the corresponding period in 2017. This increase was primarily due to an increase of $17.50 per Bbl in 
our realized oil sales price and a 12.9 MBblpd increase in oil production volumes. The increase in oil production 
volumes was attributable to 11.7 MBblpd from the Stone Combination and the Whistler Acquisition collectively, 
and 3.2 MBblpd from the Tornado II well in the Phoenix Field which commenced initial production in December 
2017. The increase in production was partially offset by unplanned third party downtime.

Natural gas revenue increased by approximately $24.7 million, or 51%, during the year ended December 31, 
2018  compared  to  the  corresponding  period  in  2017.  This  increase  was  due  to  a  17.7  MMcfpd  increase  in  gas 
production volumes, which was attributable to 18.2 MMcfpd from the Stone Combination and Whistler Acquisition 
collectively. Natural gas revenue also increased due to a $0.23 per Mcf increase in our realized gas sales price.

NGL revenue increased by approximately $19.2 million, or 115%, during the year ended December 31, 2018 
compared to the corresponding period in 2017. This increase was due to an increase of a $6.91 per Bbl increase in 
our realized NGL sales price and a 1.3 MBblpd increase in NGL volumes, 1.2 MBblpd of which was attributable to 
the Stone Combination and Whistler Acquisition collectively.

Lease operating expense. Total lease operating expense for the year ended December 31, 2018 was $163.3 
million  compared  to  $121.4  million  for  the  year  ended  December 31,  2017  an  increase  of  approximately  $41.9 
million, or 35%. This increase was primarily related to $40.7 million of lease operating expense in connection with 
the Stone Combination and $2.8 million of lease operating expense in connection with the Whistler Acquisition. In 
addition,  lease  operating  expense  increased  due  to  a  more  competitive  offshore  environment,  offset  by  an  $8.7 
million  increase  in  PHA  reimbursements.  While  total  lease  operating  expense  has  increased,  lease  operating 
expense decreased $1.84 per Boe to $9.76 per Boe as a result of increased deepwater production from the Stone 
Combination and increased production in the Phoenix Field.

Depreciation,  depletion  and  amortization.  Depreciation,  depletion  and  amortization  expense  for  the  year 
ended December 31, 2018 was $288.7 million compared to $157.3 million for the year ended December 31, 2017, 
an increase of approximately $131.4 million, or 83%. This increase was primarily due to a $2.22 per Boe, or 15%, 
increase  in  the  depletion  rate  on  our  proved  oil  and  natural  gas  properties  during  the  year  ended  December 31, 
2018. Depletion on a per Boe basis increased primarily due to an increase in proved properties related to the Stone 
Combination and higher estimated future development costs related to proved undeveloped reserves in the Phoenix 
Field.

General  and  administrative  expense.  General  and  administrative  expense  for  the  year  ended  December 31, 
2018  was  $85.8  million  compared  to  $36.7  million  for  the  year  ended  December 31,  2017,  an  increase  of 
approximately  $49.1  million,  or  134%.  This  increase  was  primarily  attributable  to  $29.2 million  in  transaction 
related costs related to the Stone Combination and $16.4 million in additional payroll cost and additional general 
and administrative expenses as a result of the combined company. 

Other operating expense. Other operating expense for the year ended December 31, 2018 was $100.3 million 
compared to $52.1 million for year ended December 31, 2017, an increase of approximately $48.2 million, or 92%. 
This increase was primarily related to an increase of approximately $32.1 million and an increase of approximately 
$16.0  million  in  workover  and  maintenance  expense  and  accretion  expense,  respectively,  in  connection  with  the 
Stone Combination. 

Price  risk  management  activities.  Price  risk  management  activities  for  year  ended  December 31,  2018 
resulted  in  income  of  $60.4  million  compared  to  an  expense  of  $27.6  million  for  the  year  ended  December 31, 
2017.  The  income  of  $60.4  million  for  the  year  ended  December 31,  2018  consists  of  $111.1  million  in  cash 
settlement  losses  offset  by  $171.6  million  in  non-cash  gains  from  the  increase  in  the  fair  value  of  our  open 
derivative  contracts.  The  expense  of  $27.6  million  for  the  year  ended  December 31,  2017  consists  of  cash 
settlement gains of $23.8 million offset by a $51.4 million in non-cash losses from the decrease in the fair value of 
our open derivatives contracts. These unrealized gains on open derivative contracts relate to production for future 
periods; however, changes in the fair value of all of our open derivative contracts are recorded as a gain or loss on 
our consolidated statements of operations at the end of each month. As a result of the derivative contracts we have 
on our anticipated production volumes through 2019, we expect these activities to continue to impact net income 
(loss) based on fluctuations in market prices for oil and natural gas.

Revenue.  Total  revenue  for  the  year  ended  December 31,  2017  was  $412.8 million  compared  to 
$258.8 million for the year ended December 31, 2016, an increase of $154.0 million, or 60%. Oil revenue increased 
by  $147.2 million,  or  74%,  during  the  year  ended  December 31,  2017.  This  increase  was  primarily  due  to  an 
increase  of  $10.37  per  Bbl  in  our  realized  oil  sales  price  and  5.3  MBblpd  increase  in  production  volumes.  The 
increase in production volumes primarily related to a 6.2 MBblpd increase from the Tornado well, GC 281 #1ST 
(T-9) in the Phoenix Field. Initial production commenced in October 2016. 

Natural  gas  revenue  increased  by  $6.2 million,  or  14%,  during  the  year  ended  December 31,  2017.  The 
increase in natural gas revenue was due to a $0.75 per Mcf increase in our realized average natural gas sales price. 
This  increase  was  offset  by  a  7.4  MMcfpd  decrease  in  production  during  the  year  ended  December 31,  2017 
primarily due to third party pipeline maintenance and weather related downtime. 

Other revenue decreased by $6.4 million, or 72%, during the year ended December 31, 2017 primarily due to 
production handling agreements fees, commencing in 2017 from certain working interest partners in the Phoenix 
Field which are recorded as a reduction to lease operating expense. 

Lease  operating  expense.  Total  lease  operating  expense  for  the  year  ended  December 31,  2017  was 
$121.4 million compared to $139.4 million for the year ended December 31, 2016, a decrease of $18.0 million, or 
13%. The decrease was primarily attributed to a $14.3 million decrease in our production facility rental expense as 
a  result  of  the  newly  negotiated  seven  year  lease  agreement  with  Helix  for  use  of  the  HP-I  beginning  July  2016 
which is accounted for as a capital lease, as well as a $2.4 million decrease in our insurance expense. 

Depreciation,  depletion  and  amortization.  Depreciation,  depletion  and  amortization  expense  for  the  year 
ended  December 31,  2017  was  $157.4 million  and  $124.7 million  for  the  year  ended  December 31,  2016,  an 
increase of $32.7 million, or 26%. The increase is primarily due to a $1.03 per Boe, or 7%, increase in the depletion 
rate on our proved oil and natural gas properties during the year ended December 31, 2017. Depletion on a per Boe 
basis increased primarily due to inclusion in the full cost pool of the capital lease asset recorded in July 2016 for 
use of the HP-I. Since the HP-I is utilized in our oil and natural gas development activities, the asset is included 
within proved property and thus depleted as part of the full cost pool. 

General  and  administrative  expense.  General  and  administrative  expense  for  the  year  ended  December 31, 
2017  was  $36.7 million  compared  to  $28.7 million  for  the  year  ended  December 31,  2016,  an  increase  of 
$8.0 million, or 28%. The increase was primarily attributable to $9.7 million in transaction related costs associated 
with  the  Stone  Combination  and  our  2017  debt  exchange,  partially  offset  by  a  decrease  in  employee  related 
expenses of $0.7 million.

Other operating expense. Other operating expense for the year ended December 31, 2017 was $52.1 million 
compared  to  $46.6 million  for  the  year  ended  December 31,  2016,  an  increase  of  $5.5 million,  or  12%.  This 
increase was primarily related to an increase of $7.8 million in facility and major wellwork due to repairs on South 
Marsh  Island  130.  This  is  partially  offset  by  a  decrease  of  $2.5 million  in  accretion  expense  for  asset  retirement 
obligations settled in 2017. 

Interest  expense.  Interest  expense  for  the  year  ended  December 31,  2017  was  $80.9 million  compared  to 
$70.4 million  for  the  year  ended  December 31,  2016,  an  increase  of  $10.5 million,  or  15%.  The  change  was 
primarily due to an increase of $11.5 million from the HP-I capital lease that began in July 2016. 

Price risk management activities. Price risk management activities expense for the year ended December 31, 
2017  was  $27.6 million  compared  to  $57.4 million  for  the  year  ended  December 31,  2016.  The  decrease  of 
$29.8 million was attributable to a $178.2 million increase in fair value of our open derivative contracts offset by a 
$148.2 million decrease in cash settlement gains for the year ended December 31, 2017. These unrealized gains on 
open derivative contracts relate to production for future periods; however, changes in the fair value of all of our 
open derivative contracts are recorded as a gain or loss in our consolidated statements of operations at the end of 
each month. As a result of the derivative contracts we have in place on our anticipated production volumes through 
2019, we expect these activities to continue to impact net income (loss) based on fluctuations in market prices for 
oil and natural gas. 

Commitments and Contingencies 

For a further discussion of our commitments and contingencies, see Part II, Item 8. Financial Statements and 
Supplementary Data — Note 11 — Commitments and Contingencies. Additionally, we are party to lawsuits arising 
in the ordinary course of our business. We cannot predict the outcome of any such lawsuit with certainty, but our 
management believes it is remote that any such pending or threatened lawsuit will have a material adverse impact 
on our financial condition. See Part I, Item 3. Legal Proceedings for additional information. 

Due to the nature of our business, we are, from time to time, involved in other routine litigation or subject to 
disputes  or  claims  related  to  business  activities,  including  workers’  compensation  claims,  employment  related 
disputes  and  civil  penalties  by  regulators.  In  the  opinion  of  our  management,  none  of  these  other  pending 
litigations, disputes or claims against us, if decided adversely, will have a material adverse effect on our financial 
condition, cash flows or results of operation. See Part I, Item 3. Legal Proceedings for additional information. 

Supplemental Non-GAAP Measure 

Adjusted EBITDA 

“Adjusted EBITDA” is not a measure of net income (loss) as determined by GAAP. We use this measure as 
a  supplemental  measure  because  we  believe  it  provides  meaningful  information  to  our  investors.  We  define 
Adjusted  EBITDA  as  net  income  (loss)  plus  interest  expense,  income  tax  expense,  depreciation,  depletion  and 
amortization, accretion expense, loss on debt extinguishment, transaction related costs, the net change in the fair 
value of derivatives (mark to market effect, net of cash settlements and premiums related to these derivatives), non-
cash (gain) loss on sale of assets, non-cash write-down of oil and natural gas properties, non-cash write-down of 
other well equipment inventory and non-cash equity based compensation expense. We believe the presentation of 
Adjusted EBITDA is important to provide management and investors with (i) additional information to evaluate, 
with  certain  adjustments,  items  required  or  permitted  in  calculating  covenant  compliance  under  our  debt 
agreements, (ii) important supplemental indicators of the operational performance of our business, (iii) additional 
criteria for evaluating our performance relative to our peers and (iv) supplemental information to investors about 
certain  material  non-cash  and/or  other  items  that  may  not  continue  at  the  same  level  in  the  future.  Adjusted 
EBITDA  has  limitations  as  an  analytical  tool  and  should  not  be  considered  in  isolation  or  as  a  substitute  for 
analysis of our results as reported under GAAP or as an alternative to net income (loss), operating income (loss) or 
any other measure of financial performance presented in accordance with GAAP.

The  adjustments  for  the  derivative  fair  value  (gains)  losses  and  net  cash  receipts  on  settled  commodity  derivative  instruments have  the 
effect  of  adjusting  net  loss  for  changes  in  the  fair  value  of  derivative  instruments,  which  are  recognized  at  the  end  of  each  accounting 
period  because  we  do  not  designate  commodity  derivative  instruments  as  accounting  hedges.  This  results  in  reflecting  commodity 
derivative gains and losses within Adjusted EBITDA on a cash basis during the period the derivatives settled. 

Liquidity and Capital Resources 

Overview 

Our primary sources of liquidity are cash generated by our operations and borrowings under our Bank Credit 
Facility.  Our  primary  uses  of  cash  are  for  capital  expenditures,  working  capital,  debt  service  and  for  general 
corporate purposes. As of December 31, 2018, our available liquidity (cash plus available capacity under the Bank 
Credit Facility) was $460.3 million.  

As of December 31, 2018, total debt, net of discount and deferred financing costs, was approximately $655.3 
million,  comprised  of  our  $381.2  million  aggregate  principal  amount  of  the  New  Second  Lien  Notes  and  $6.1 
million aggregate principal amount of our 7.50% Stone Senior Notes, $257.4 million outstanding under our Bank 
Credit Facility, and $10.6 million aggregate principal amount of the Building Loan. We were in compliance with 
all  debt  covenants  at  December 31,  2018.  For  additional  details  on  our  debt,  see  Part  II,  Item  8.  Financial 
Statements and Supplementary Data — Note 6 — Debt. 

Based  on  our  current  level  of  operations  and  available  cash,  we  believe  our  cash  flows  from  operations, 
combined with availability under the Bank Credit Facility, provide sufficient liquidity to fund our board approved 
2019  capital  spending  project  of  $465.0 million  to  $485.0 million.  However,  our  ability  to  (i) generate  sufficient 
cash flows from operations or obtain future borrowings under the Bank Credit Facility, and (ii) repay or refinance 
any  of  our  indebtedness  on  commercially  reasonable  terms  or  at  all  for  any  potential  future  acquisitions,  joint 
ventures or other similar transactions, depends on operating and economic conditions, some of which are beyond 
our control. To the extent possible, we have attempted to mitigate certain of these risks (e.g. by entering into oil 
and natural gas derivative contracts to reduce the financial impact of downward commodity price movements on a 
substantial  portion  of  our  anticipated  production),  but  we  could  be  required  to,  or  we  or  our  affiliates  may  from 
time to time, take additional future actions on an opportunistic basis. To address further changes in the financial 
and/or commodity markets, future actions may include, without limitation, raising debt, including secured debt, or 
issuing equity to directly or independently repurchase or refinance our outstanding debt. 

As  of  December 31,  2018,  we  had  obtained  performance  bonds  primarily  related  to  P&A  of  wells  and 
removal of facilities in the United States Gulf of Mexico and to guarantee the completion of the minimum work 
program  under  the  PSCs  totaling  approximately  $644.1  million.  In  July  2016,  BOEM  issued  the  2016  NTL  to 
clarify  the  procedures  and  guidelines  the  BOEM  Regional  Directors  use  to  determine  if  and  when  additional

financial assurances may be required for OCS leases, ROWs and RUEs to meet BOEM’s estimate of the lessees’ 
decommissioning obligations. The 2016 NTL became effective in September 2016 and allows qualifying operators 
to self-insure for an amount up to 10% of their tangible net worth. The 2016 NTL also provides for operators to 
propose  a  tailored  plan  subject  to  BOEM  approval  that  allows  the  posting  of  additional  financial  assurance  over 
time. However, BOEM has indefinitely delayed beyond June 30, 2017 implementation of the 2016 NTL, except in 
certain circumstances where there is a substantial risk of nonperformance of the interest holder’s decommissioning 
liabilities,  to  allow  BOEM  time  to  reconsider  a  number  of  regulatory  initiatives.  We  received  the  BOEM  2016 
Orders  in  late  2016  ordering  us  to  secure  financial  assurances  in  the  form  of  additional  security  in  material 
amounts.  We  entered  into  discussions  with  BOEM  regarding  the  requested  security  and  submitted  a  proposed 
tailored plan for the posting of additional financial security to the agency for review. However, as noted, BOEM 
has indefinitely delayed implementation beyond June 30, 2017 of the 2016 NTL, has rescinded the BOEM 2016 
Orders while BOEM reviews its financial assurance program and, to date, has taken no action with respect to our 
previously submitted proposed tailored plan. We remain in active discussion with our government regulators and 
industry  peers  with  regard  to  any  future  rule  making  and  financial  assurance  requirements.  Notwithstanding  the 
2016  NTL,  BOEM  may  also  increase  its  financial  assurance  requirements  mandated  by  rule  for  all  companies 
operating  in  federal  waters.  BOEM  could  also  make  new  demands  for  additional  financial  security  in  material 
amounts  in  the  event  the  agency  chooses  to  implement  the  2016  NTL,  and  such  amounts  may  be  material  and 
exceed  our  capability  to  provide  additional  financial  assurance.  The  future  cost  of  compliance  with  our  existing 
supplemental  bonding  requirements,  including  with  respect  to  any  tailored  plan  that  is  subject  to  approval  by 
BOEM, the 2016 NTL, as well as any other future directives or any other changes to BOEM’s rules applicable to 
us  or  our  subsidiaries’  properties,  could  materially  and  adversely  affect  our  financial  condition,  cash  flows  and 
results of operations. 

New Second Lien Notes, 7.50% Stone Senior Notes 

In connection with the Stone Combination, we consummated the Transactions contemplated by the Exchange 
Agreement, pursuant to which (i) the Apollo Funds and Riverstone Funds contributed $102.0 million in aggregate 
principal amount of 9.75% Senior Notes to us in exchange for our common stock; (ii) the holders of 11.00% Bridge 
Loans exchanged such 11.00% Bridge Loans for $172.0 million aggregate principal amount of New Second Lien 
Notes and (iii) the Franklin Noteholders and the MacKay Noteholders exchanged their 7.50% Stone Senior Notes 
for $137.4 million aggregate principal amount of New Second Lien Notes. An additional $81.5 million of 7.50% 
Stone  Senior  Notes  held  by  non-affiliates  were  also  exchanged  for  New  Second  Lien  Notes  pursuant  to  an 
exchange offer and consent solicitation in connection with the Stone Combination. 

The  exchange  of  7.50%  Stone  Senior  Notes  for  New  Second  Lien  Notes  was  accounted  for  as  a  debt 
modification.  Under  a  debt  modification,  a  new  effective  interest  rate  that  equates  the  revised  cash  flows  to  the 
carrying amount of the New Second Lien Notes is computed and applied prospectively. Costs incurred with third 
parties  directly  related  to  the  modification  are  expensed  as  incurred.  We  incurred  approximately  $4.3 million  of 
transaction fees related to the exchange of 11.00% Bridge Loans and 7.50% Stone Senior Notes into New Second 
Lien  Notes,  which  were  expensed  and  reflected  in  general  and  administrative  expense  during  the  year  ended 
December 31,  2018,  respectively.  We  also  paid  $9.3 million  in  work  fees  to  debt  holders,  which  are  reflected  as 
debt discount reducing long-term debt on the consolidated balance sheet at December 31, 2018. 

11.00%  Second-Priority  Senior  Secured  Notes—due  April  2022.  The  New  Second  Lien  Notes  were  issued 
pursuant to an indenture dated as of the Closing Date, between the Talos Issuers, the subsidiary guarantors party 
thereto and Wilmington Trust, National Association, as trustee and collateral agent. The New Second Lien Notes 
mature  April 3,  2022  and  have  interest  payable  semi-annually  each  April 15  and  October 15.  Prior  to  May 10, 
2019,  we  may,  at  our  option,  redeem  all  or  a  portion  of  the  New  Second  Lien  Notes  at  100%  of  the  principal 
amount plus accrued and unpaid interest and a make-whole premium. Thereafter, we may redeem all or a portion of 
the  New  Second  Lien  Notes  at  redemption  prices  decreasing  annually  from  105.5%  to  100.0%  plus  accrued  and 
unpaid interest. 

7.50%  Senior  Secured  Notes—due  May  2022. The  7.50%  Stone  Senior  Notes  represent  the  remaining 
$6.1 million of long-term debt assumed in the Stone Combination that were not exchanged for New Second Lien 
Notes  pursuant  to  the  exchange  offer  and  consent  solicitation,  and  thus  remain  outstanding.  As  a  result  of  the 
Exchange Offer and Consent Solicitation, substantially all of the restrictive covenants relating to the 7.50% Stone 
Senior  Notes  have  been  removed  and  collateral  securing  the  7.50%  Stone  Senior  Notes  has  been  released.  The 
7.50%  Stone  Senior  Notes  mature  May 31,  2022  and  have  interest  payable  semiannually  each  May 31  and

November 30. Prior to May 31, 2020, we may, at our option, redeem all or a portion of the 7.50% Stone Senior 
Notes at 100% of the principal amount plus accrued and unpaid interest and a make-whole premium. Thereafter, 
we may redeem all or a portion of the 7.50% Stone Senior Notes at redemption prices decreasing annually from 
105.625% to 100.0% plus accrued and unpaid interest. 

Bank Credit Facility 

Talos  Production,  our  wholly  owned  subsidiary,  executed  the  Bank  Credit  Facility  in  conjunction  with  the 
Stone Combination with a syndicate of financial institutions with an initial borrowing base of $600.0 million. The 
Bank Credit Facility is currently scheduled to mature on May 10, 2022. 

The  Bank  Credit  Facility  bears  interest  based  on  the  borrowing  base  usage,  at  the  applicable  London 
InterBank Offered Rate, plus applicable margins ranging from 2.75% to 3.75% or an alternate base rate based on 
the federal funds effective rate plus applicable margins ranging from 1.75% to 2.75%. In addition, we are obligated 
to pay a commitment fee of 0.50% on the unfunded portion of the commitments under the Bank Credit Facility. 
The Bank Credit Facility has certain debt covenants, the most restrictive of which requires that we maintain a total 
debt to EBITDAX Ratio (as defined in the Bank Credit Facility) of no greater than 3.00 to 1.00 each quarter. We 
must  also  maintain  a  current  ratio  no  less  than  1.00  to  1.00  each  quarter.  According  to  the  Bank  Credit  Facility, 
undrawn  commitments  are  included  in  current  assets  in  the  current  ratio  calculation.  The  Bank  Credit  Facility  is 
secured by substantially all of our oil and natural gas assets. The Bank Credit Facility is fully and unconditionally 
guaranteed by us and certain of our wholly-owned subsidiaries. 

The Bank Credit Facility provides for determination of the borrowing base based on our proved producing 
reserves  and  a  portion  of  our  PUD  reserves.  The  borrowing  base  is  redetermined  by  the  lenders  at  least  semi-
annually during the second quarter and fourth quarter each year. On November 16, 2018, the borrowing base was 
increased  from  $600.0  million  to  $850.0  million.  We  elected  to  maintain  the  $600.0  million  commitment  based 
upon our current liquidity needs. The next redetermination is scheduled for April 2019.

As of December 31, 2018, commitments under our borrowing base was set at $600.0 million, of which no 
more than $200 million can be used as letters of credit. The amount that we are able to borrow with respect to the 
borrowing  base  is  subject  to  compliance  with  the  financial  covenants  and  other  provisions  of  the  Bank  Credit 
Facility.  We  were  in  compliance  with  all  debt  covenants  at  December 31,  2018.  As  of  December 31,  2018,  the 
Bank  Credit  Facility  had  approximately  $320.3  million  of  undrawn  commitments  (taking  into  account  $14.7 
million letters of credit and $265.0 million drawn from the Bank Credit Facility).

Building Loan 

In connection with the Stone Combination, we assumed Stone’s Building Loan maturing on November 20, 
2030.  The  Building  Loan  bears  interest  at  a  rate  of 4.20% per  annum  and  is  to  be  repaid  in 180 equal  monthly 
installments of approximately $0.1 million. As of December 31, 2018, the outstanding balance under the Building 
Loan totaled $10.6 million. The Building Loan is collateralized by our two office buildings in Lafayette, Louisiana. 
Under the financial covenants of the Building Loan, we must maintain a ratio of EBITDA to Net Interest Expense 
of not less than 2.00 to 1.00. In addition, the Building Loan contains certain customary restrictions or requirements 
with respect to change of control and reporting responsibilities. We are in compliance with all covenants under the 
Building Loan as of December 31, 2018. 

2018 Senior Notes 

9.75%  Senior  Notes—due  February  2018.  The  9.75%  Senior  Notes  due  2018  were  issued  by  the  Talos 
Issuers pursuant to an indenture dated February 6, 2013, among the Talos Issuers, the subsidiary guarantors party 
thereto  and  the  trustee.  On  February 15,  2018,  the  Talos  Issuers  redeemed  the  remaining  $25.0 million  principal 
amount of the 9.75% Senior Notes due 2018 at par.

Operating  Activities.  Net  cash  provided  by  operating  activities  increased  $87.4  million  in  2018  from  2017 
primarily  attributable  to  an  increase  in  revenue,  offset  by  a  decrease  in  cash  settlements  on  derivatives  and 
transaction related cost related to the Stone  Combination.  Net  cash  provided  by  operating  activities  increased 
$59.9 million from 2017 to 2016 primarily due to an increase in revenue, offset by a decrease in cash settlements 
gains on our derivative contracts. 

Investing Activities. Net cash used in (provided by) investing activities increased $195.1 million in 2018 from 
2017  primarily  attributable  to  $280.9  million  of  cash  received  from  the  Stone  Combination  and  Whistler 
Acquisition, partially offset by an increase of $85.7 million in capital expenditures. The increase of $41.3 million in 
net cash used in investing activities from 2017 to 2016 primarily related to a decrease in capital expenditures.

Financing Activities. Net cash used in (provided by) financing activities increased by $174.8 million in 2018 
from 2017 primarily attributable to the repayment of $403.0 million related to the LLC Bank Credit Facility, $54.0 
million related to the repayment of the Bank Credit Facility, $25.3 million related to the redemption of our 2018 
Senior  Notes  and  other  long-term  debt,  $17.0  million  in  deferred  financing  cost,  partially  offset  by  proceeds 
received  from  the  Bank  Credit  Facility  of  $319.0  million.  Net  cash  provided  by  financing  activities  decreased 
$110.0  million  in  2017  from  2016  primarily  related  to  a  reduction  of  $91.9  million  net  contribution  from  our 
Sponsors. 

Capital  Expenditures.  We  fund  exploration  and  development  activities  primarily  through  operating  cash 
flows,  cash  on  hand,  and  through  borrowings  under  the  Bank  Credit  Facility,  if  necessary.  Historically,  we  have 
funded  significant  property  acquisitions  with  the  issuance  of  senior  notes,  borrowings  under  the  Bank  Credit 
Facility and through additional equity issuances. We occasionally adjust our capital budget in response to changing 
operating cash flow forecasts and market conditions, including the prices of oil, natural gas and NGLs, acquisition 
opportunities and the results of our exploration and development activities. 

The following is a table of our capital expenditures, excluding acquisitions, for the year ended December 31,

Includes vessel commitments we will utilize for certain deep water well intervention and decommissioning activities. These commitments 
represent gross contractual obligations and accordingly, other joint owners in the properties operated by us will be billed for their working 
interest share of such costs. Includes commitments for drilling rigs and Helix’s Q4000 well intervention vessel we will utilize for certain 
deep water well intervention and decommissioning activities.

Includes committed purchase orders to execute planned future drilling and completion activities. Includes seismic use agreements. 
This table does not include our estimated discounted liability for dismantlement, abandonment and restoration costs of oil and natural gas 
properties  of  $382.8  million  as  of  December 31,  2018.  For  additional  information  regarding  these  liabilities,  please  see  Part  II,  Item  8. 
Financial Statements and Supplementary Data — Note 4 — Property, Plant and Equipment. 

Performance  Bonds.  As  of  December 31,  2018  and  2017,  we  had  secured  performance  bonds  primarily 
related  to  P&A  of  wells  and  removal  of  facilities  and  executing  the  minimum  work  program  under  the  PSCs 
totaling  approximately  $644.1  million  and  $287.8  million,  respectively.  As  of  December 31,  2018  and  2017,  we 
had $14.7 million and $4.9 million, respectively, in letters of credit issued under our Bank Credit Facility and our 
previous credit facility primarily for the P&A of wells and the removal of facilities. 

For additional information about certain of our obligations and contingencies, see Part II, Item 8. Financial 

Statements and Supplementary Data — Note 11 — Commitments and Contingencies. 

Critical Accounting Policies and Estimates 

The  preparation  of  financial  statements  in  conformity  with  GAAP  requires  our  management  to  make 
estimates  and  assumptions  that  affect  the  reported  amount  of  assets,  liabilities,  revenue  and  expense,  and  the 
disclosures of contingent assets and liabilities. We consider our critical accounting estimates to be those estimates 
that require complex or subjective judgment in the application of the accounting policy and that could significantly 
impact our financial results based on changes in those judgments. Changes in facts and circumstances may result in 
revised estimates and actual results may differ materially from those estimates. Our management has identified the 
following critical accounting estimates. Our significant accounting policies that have been implemented or changed 
since December 31, 2017 are described in Part II, Item 8. Financial Statements and Supplementary Data — Note 2 
— Summary of Significant Accounting Policies. 

Oil and Natural Gas Properties 

We follow the full cost method of accounting for oil and natural gas exploration and development activities. 
Under  the  full  cost  method,  substantially  all  costs  incurred  in  connection  with  the  acquisition,  development  and 
exploration  of  oil  and  natural  gas  reserves  are  capitalized.  These  capitalized  amounts  include  the  internal  costs 
directly  related  to  acquisition,  development  and  exploration  activities,  asset  retirement  costs  and  capitalized 
interest. Under the full cost method, dry hole costs and geological and geophysical costs are capitalized into the full 
cost pool, which is subject to amortization and assessed for impairment on a quarterly basis through a ceiling test 
calculation as discussed below. 

76

6696_10K.pdf

 
 
   
   
   
 
  
     
     
     
     
     
  
  
  
  
Capitalized costs associated with proved reserves are amortized on a country by country basis over the life of 
the  total  proved  reserves  using  the  unit  of  production  method,  computed  quarterly.  Conversely,  capitalized  costs 
associated  with  unproved  properties  and  related  geological  and  geophysical  costs,  wells  currently  drilling  and 
capitalized interest are initially excluded from the amortizable base. We transfer unproved property costs into the 
amortizable  base  when  properties  are  determined  to  have  proved  reserves  or  when  we  have  completed  an 
evaluation of the unproved properties resulting in an impairment. We evaluate each of these unproved properties 
individually  for  impairment  at  least  quarterly.  Additionally,  the  amortizable  base  includes  future  development 
costs,  dismantlement,  restoration  and  abandonment  costs,  net  of  estimated  salvage  values,  and  geological  and 
geophysical  costs  incurred  that  cannot  be  associated  with  specific  unproved  properties  or  prospects  in  which  we 
own a direct interest. 

Our capitalized costs are limited to a ceiling based on the present value of future net revenues from proved 
reserves,  discounted  at  10%,  plus  the  lower  of  cost  or  estimated  fair  value  of  unproved  oil  and  natural  gas 
properties not being amortized. Any costs in excess of the ceiling are recognized as a non-cash impairment expense 
on  our  consolidated  statement  of  operations  and  an  increase  to  accumulated  depreciation,  depletion  and 
amortization  on  our  consolidated  balance  sheet.  The  expense  will  not  be  reversed  in  future  periods,  even  though 
higher  oil,  natural  gas  and  NGL  prices  may  subsequently  increase  the  ceiling.  We  perform  this  ceiling  test 
calculation each quarter. In accordance with SEC rules and regulations, we utilize SEC Pricing when performing 
the ceiling test. We also hold prices and costs constant over the life of the reserves, even though actual prices and 
costs of oil and natural gas are often volatile and may change from period to period. The ceiling test computation 
did not result in a write-down of our oil and natural gas properties during the year ended December 31, 2018, 2017 
and 2016. 

Under the full cost method of accounting for oil and natural gas operations, assets whose costs are currently 
being  depreciated,  depleted  or  amortized  are  assets  in  use  in  the  earnings  activities  of  the  enterprise  and  do  not 
qualify  for  capitalization  of  interest  cost.  Investments  in  unproved  properties  for  which  exploration  and 
development  activities  are  in  progress  and  other  major  development  projects  that  are  not  being  currently 
depreciated, depleted or amortized are assets qualifying for capitalization of interest costs. 

When we sell or convey interests in oil and natural gas properties, we reduce our oil and natural gas reserves 
for the amount attributable to the sold or conveyed interest. We do not recognize a gain or loss on sales of oil and 
natural  gas  properties,  unless  those  sales  would  significantly  alter  the  relationship  between  capitalized  costs  and 
proved reserves. We treat sales proceeds on non-significant sales as reductions to the cost of our oil and natural gas 
properties. 

We recognize transportation costs as a component of direct lease operating expense when we are the shipper 
of  the  product.  Such  costs  during  the  year  ended  December 31,  2018,  2017  and  2016  were  $12.5 million, 
$10.3 million and $9.1 million, respectively. 

Proved Reserve Estimates 

We estimate our proved oil, natural gas and NGL reserves in accordance with the guidelines established by 
the  SEC.  Proved  oil,  natural  gas  and  NGL  reserves  are  those  quantities  of  oil,  natural  gas  and  NGLs,  which,  by 
analysis  of  geoscience  and  engineering  data,  can  be  estimated  with  reasonable  certainty  to  be  economically 
producible in future periods from known reservoirs and under existing economic conditions, operating methods and 
governmental regulations. Prices are determined using SEC pricing. 

Our  estimates  of  proved  reserves  are  made  using  available  geological  and  reservoir  data,  as  well  as 
production  performance  data.  The  estimates  of  proved  reserves  are  reviewed  annually  by  internal  reservoir 
engineers and revised, either upward or downward, as warranted by additional data. Revisions are necessary due to 
changes in, among other things, reservoir performance, prices, economic conditions and governmental restrictions. 
Decreases in price, for example, may cause a reduction in some proved reserves due to reaching economic limits at 
an  earlier  projected  date.  A  material  adverse  change  in  the  estimated  volumes  of  proved  reserves  could  have  a 
negative impact on depreciation, depletion and amortization or could result in property impairments. 

Fair Value Measure of Financial Instruments 

Our  financial  instruments  generally  consisted  of  cash  and  cash  equivalents,  restricted  cash,  accounts 
receivable, commodity derivatives, accounts payable and debt as of December 31, 2018. The carrying amount of 
cash and cash equivalents, restricted cash, accounts receivable and accounts payable approximates fair value due to 
the highly liquid nature of these instruments. 

77

6696_10K.pdf

Fair value accounting standards define fair value, establish a consistent framework for measuring fair value 
and stipulate the related disclosure requirements for each major asset and liability category measured at fair value 
on either a recurring or nonrecurring basis. These standards also clarify fair value as an exit price, presenting the 
amount  that  would  be  received  to  sell  an  asset  or  paid  to  transfer  a  liability,  in  an  orderly  transaction  between 
market participants. We follow a three-level hierarchy, prioritizing and defining the types of inputs used to measure 
fair value depending on the degree to which they are observable as follows: 

Level 1—Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities 

in active markets. 

Level 2—Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active 
markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the 
full term of the financial statement. 

Level 3—Inputs to the valuation methodology are unobservable (little or no market data), which require us to 

develop our own assumptions, and are significant to the fair value measurement. 

Assets  and  liabilities  measured  at  fair  value  are  based  on  one  or  more  of  three  valuation  techniques.  The 

valuation techniques are as follows: 

Market  Approach—Prices  and  other  relevant  information  generated  by  market  transactions  involving 

identical or comparable assets or liabilities. 

Cost  Approach—Amount  that  would  be  required  to  replace  the  service  capacity  of  an  asset  (replacement 

cost). 

Income Approach—Techniques to convert expected future cash flows to a single present value amount based 

on market expectations (including present value techniques, option-pricing and excess earnings models). 

Authoritative guidance on financial instruments requires certain fair value disclosures to be presented. The 
estimated  fair  value  amounts  have  been  determined  using  available  market  information  and  valuation 
methodologies. Considerable judgment is required in interpreting market data to develop the estimates of fair value. 
The use of different assumptions or valuation methodologies may have a material effect on the estimated fair value 
amounts. 

Asset Retirement Obligations 

We  are  required  to  record  our  asset  retirement  obligations  at  fair  value  in  the  period  such  obligations  are 
incurred with the associated asset retirement costs being capitalized as part of the carrying cost of the asset. Our 
asset  retirement  obligations  consist  of  estimated  costs  for  dismantlement,  removal,  site  reclamation  and  similar 
activities associated with our oil and natural gas properties. The estimate of the asset retirement cost is determined, 
inflated  to  an  estimated  future  value  using  a  ten  year  average  of  the  Consumer  Price  Index  and  discounted  to 
present  value  using  our  credit-adjusted  risk-free  rate.  Accretion  of  the  liability  is  recognized  for  changes  in  the 
value of the liability as a result of the passage of time over the estimated productive life of the related assets as the 
discounted liabilities are accreted to their expected settlement values. 

Revenue Recognition, Imbalances and Production Handling Fees 

We  record  revenues  from  the  sale  of  oil,  natural  gas  and  NGLs  based  on  quantities  of  production  sold  to 
purchasers under short-term contracts (less than twelve months) at market prices when delivery to the customer has 
occurred, title has transferred, prices are fixed and determinable and collection is reasonably assured. This occurs 
when production has been delivered to a pipeline or when a barge lifting has occurred. 

Under  previous  accounting  guidance,  we  used  the  entitlement  method  to  account  for  sales  and  production. 
Under the entitlement method, revenue was recorded based on our entitled share of production with any difference 
recorded as an imbalance on the consolidated balance sheet. Upon the adoption of ASC 606, revenues are recorded 
based on the actual sales volumes sold to purchasers. An imbalance receivable or payable is recorded only to the 
extent the imbalance is in excess of its share of remaining proved developed reserves in an underlying property. 
The  change  in  accounting  method  from  the  entitlements  method  to  the  sales  method  resulted  in  an  immaterial 
cumulative-effect adjustment to members’ deficit on the date of adoption. Our imbalances are recorded gross on 
our consolidated balance sheets. At December 31, 2018, our imbalance receivable was approximately $1.7 million 
and  imbalance  payable  was  approximately  $2.5 million.  At  December 31,  2017,  our  imbalance  receivable  was 
approximately $2.1 million and imbalance payable was approximately $2.7 million. 

78

6696_10K.pdf

Under  previous  accounting  guidance,  we  presented  certain  reimbursements  for  costs  from  certain  third 
parties  as  other  revenue  on  the  consolidated  statement  of  operations.  Upon  the  adoption  of  ASC 606,  the 
reimbursements  are  presented  as  a  reduction  of  direct  lease  operating  expense  on  the  consolidated  statement  of 
operations. The impact of the reclassification for the year ended December 31, 2018 was immaterial. 

Income Taxes 

Our provision for income taxes includes both state, federal and foreign taxes. We record our federal income 
taxes in accordance with accounting for income taxes under GAAP which results in the recognition of deferred tax 
assets and liabilities for the expected future tax consequences of temporary differences between the book carrying 
amounts and the tax basis of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax 
rates expected to apply to taxable income in the years in which those temporary differences and carryforwards are 
expected  to  be  recovered  or  settled.  The  effect  on  deferred  tax  assets  and  liabilities  of  a  change  in  tax  rates  is 
recognized in income in the period that includes the enactment date. A valuation allowance is established to reduce 
deferred tax assets if it is more likely than not that the related tax benefits will not be realized. As of December 31, 
2018, we believe it is more likely than not that the net deferred tax asset will not be realized and therefore have 
recorded a valuation allowance.

We apply significant judgment in evaluating our tax positions and estimating our provision for income taxes. 
During  the  ordinary  course  of  business,  there  are  many  transactions  and  calculations  for  which  the  ultimate  tax 
determination is uncertain. The actual outcome of these future tax consequences could differ significantly from our 
estimates, which could impact our financial position, results of operations and cash flows. 

We also account for uncertainty in income taxes recognized in the financial statements in accordance with 
GAAP by prescribing a recognition threshold and measurement attribute for a tax position taken or expected to be 
taken  in  a  tax  return.  Authoritative  guidance  for  accounting  for  uncertainty  in  income  taxes  requires  that  we 
recognize  the  financial  statement  benefit  of  a  tax  position  only  after  determining  that  the  relevant  tax  authority 
would more likely than not sustain the position following an audit. For tax positions meeting the more likely than 
not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50% 
likelihood of being realized upon ultimate settlement with the relevant tax authority.

Accounting Standards applicable to us. 

Item 7A. Quantitative and Qualitative Disclosures About Market Risk 

We are currently exposed to market risk in two areas: commodity prices and, to a lesser extent, interest rate 
risk. Our risk management activities involve the use of derivative financial instruments to mitigate the impact of 
market price risk exposures primarily related to our oil and natural gas production. All derivatives are recorded on 
the consolidated balance sheet at fair value with settlements of such contracts and changes in the unrealized fair 
value recorded as price risk management activities income (expense) on the consolidated statements of operations 
in each period. 

Commodity Price Risks 

Oil and natural gas prices can fluctuate significantly and have a direct impact on our revenues, earnings and 
cash flow. During year ended December 31, 2018, our average oil price realizations after the effect of derivatives 
increased 9% to $57.12 per Bbl from $52.46 per Bbl in the comparable 2017 period. Our average natural gas prices 
realizations after the effect of derivatives increased 8% during the year ended December 31, 2018 to $3.16 per Mcf 
from $2.93 per Mcf in the comparable 2017 period.

Price Risk Management Activities 

We have attempted to mitigate commodity price risk and stabilize cash flows associated with our forecasted 
sales of oil and natural gas production through the use of oil and natural gas swaps. These contracts will impact our 
earnings as the fair value of these derivatives changes. Our derivatives will not mitigate all of the commodity price 
risks  of  our  forecasted  sales  of  oil  and  natural  gas  production  and,  as  a  result,  we  will  be  subject  to  commodity 
price risks on our remaining forecasted production. 

We had commodity derivative instruments in place to reduce the price risk associated with future production 
of 9,146 MBbls of crude oil and 11,133 MMBtu of natural gas at December 31, 2018, with a net derivative liability 
position of $74.9 million. For additional information regarding our commodity derivative instruments, see Part II, 
Item 8. Financial Statements and Supplementary Data — Note 5 — Financial Instruments, included elsewhere in 
this report. The table below presents the hypothetical sensitivity of our commodity price risk management activities 
to  changes  in  fair  values  arising  from  immediate  selected  potential  changes  in  oil  and  natural  gas  prices  at 
December 31, 2018 (in thousands):

Variable Interest Rate Risks 

We  had  total  debt  outstanding  of  $655.3  million  at  December 31,  2018,  net  of  unamortized  original  issue 
discount and deferred financing costs. Of this, $397.9 million was from our New Second Lien Notes, 7.50% Stone 
Senior  Notes  and  Building  Loan,  which  bear  interest  at  fixed  rates.  The  remaining  $257.4  million  is  from 
borrowings  under  our  Bank  Credit  Facility  with  variable  interest  rates.  We  are  subject  to  the  risk  of  changes  in 
interest rates under our Bank Credit Facility. In addition, the terms of our Bank Credit Facility require us to pay 
higher interest rates as we utilize a larger percentage of our available borrowing base. We manage our interest rate 
exposure by maintaining a combination of fixed and variable rate debt and monitoring the effect of market changes 
in interest rates. We believe our interest rate risk exposure is partially mitigated as a result of fixed interest rates on 
61% of our debt. The interest rate on our variable rate debt at December 31, 2018 was 5.46%. A 10% change in the 
interest  rate  on  this  variable  rate  debt  balance  at  December 31,  2018  would  change  interest  expense  for  the  year 
ended December 31, 2018 by approximately $0.7 million.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our  management,  with  the  participation  of  our  chief  executive  officer  and  chief  financial  officer,  has 
evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a- 15(e) and 15d- 15(e) 
under the Exchange Act) as of the end of the period covered by this Annual Report on Form 10-K. Based on such 
evaluation, our chief executive officer and chief financial officer have concluded that as of December 31, 2018, our 
disclosure  controls  and  procedures  are  designed  at  a  reasonable  assurance  level  and  are  effective  to  provide 
reasonable  assurance  that  information  we  are  required  to  disclose  in  reports  that  we  file  or  submit  under  the 
Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and 
forms  of  SEC,  and  that  such  information  is  accumulated  and  communicated  to  our  management,  including  our 
chief  executive  officer  and  chief  financial  officer,  as  appropriate,  to  allow  timely  decisions  regarding  required 
disclosures.

Management’s Annual Report on Internal Control over Financial Reporting

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial 
reporting  as  defined  in  Rule  13a-15(f)  under  the  Exchange  Act.  Management  conducted  an  assessment  of  the 
effectiveness  of  our  internal  control  over  financial  reporting  based  on  the  criteria  set  forth  in  Internal  Control—
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 
framework). Based on the assessment, management has concluded that its internal control over financial reporting 
was  effective  as  of  December  31,  2018  to  provide  reasonable  assurance  regarding  the  reliability  of  financial 
reporting and the preparation of financial statements in accordance with U.S. GAAP. Our independent registered 
public  accounting  firm,  Ernst  &  Young  LLP,  has  issued  an  audit  report  with  respect  to  our  internal  control  over 
financial reporting, which is included in this Annual Report on Form 10-K.

Changes in Internal Control over Financial Reporting

There were no changes in our internal controls over financial reporting identified in management's evaluation 
pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the fourth quarter of 2018 that  materially 
affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of 
Talos Energy Inc. 

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Talos Energy Inc. (the Company) as of 
December 31, 2018 and 2017, the related consolidated statements of operations, changes in stockholders’ equity 
(deficit), and cash flows for each of the three years in the period ended December 31, 2018, and the related notes 
(collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial 
statements present fairly, in all material respects, the financial position of the Company at December 31, 2018 and 
2017, and the results of its operations and its cash flows for each of the three years in the period ended December 
31, 2018, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2018, based 
on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (2013 framework), and our report dated March 13, 2019 expressed an 
unqualified opinion thereon. 

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an 
opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered 
with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. 
federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the 
PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether the financial statements are free of material 
misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of 
material misstatement of the financial statements, whether due to error or fraud, and performing procedures that 
respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and 
disclosures in the financial statements. Our audits also included evaluating the accounting principles used and 
significant estimates made by management, as well as evaluating the overall presentation of the financial 
statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ Ernst & Young LLP

We have served as the Company’s auditor since 2010.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of 
Talos Energy Inc. 

Opinion on Internal Control Over Financial Reporting

We have audited Talos Energy Inc.’s internal control over financial reporting as of December 31, 2018, based on 
criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Talos Energy 
Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of 
December 31, 2018, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2018 and 2017, the 
related consolidated statements of operations, changes in stockholders’ equity (deficit) and cash flows for each of 
the three years in the period ended December 31, 2018, and the related notes (collectively referred to as the 
“consolidated financial statements”) and our report dated March 13, 2019 expressed an unqualified opinion 
thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and 
for its assessment of the effectiveness of internal control over financial reporting included in the accompanying 
Report of Management on Internal Control over Financial Reporting. Our responsibility is to express an opinion on 
the Company’s internal control over financial reporting based on our audit. We are a public accounting firm 
registered with the PCAOB and are required to be independent with respect to the Company in accordance with the 
U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission 
and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting 
was maintained in all material respects. 

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a 
material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on 
the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We 
believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance 
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in 
accordance with generally accepted accounting principles. A company’s internal control over financial reporting 
includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, 
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable 
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance 
with generally accepted accounting principles, and that receipts and expenditures of the company are being made 
only in accordance with authorizations of management and directors of the company; and (3) provide reasonable 
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’
s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect 
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that 
controls may become inadequate because of changes in conditions, or that the degree of compliance with the 
policies or procedures may deteriorate.

TALOS ENERGY INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2018

Note 1 — Formation and Basis of Presentation

Formation and Nature of Business

Talos  Energy  Inc.  (“Talos”  or  the  “Company”)  is  a  technically  driven  independent  exploration  and 
production  company  with  operations  in  the  United  States  (“U.S.”)  Gulf  of  Mexico  and  offshore  Mexico.  The 
Company’s focus in the U.S. Gulf of Mexico is the acquisition of deep water assets with existing infrastructure and 
the exploration, exploitation and development of such assets in key geological trends. Offshore Mexico provides 
high  impact  exploration  opportunities  in  an  oil  rich  emerging  basin.  The  Company  uses  access  to  an  extensive 
seismic  database  and  its  deep  technical  expertise  to  identify,  acquire  and  exploit  attractive  assets  with  robust 
economic profiles. 

Talos  Energy  Inc.  was  formed  in  connection  with  the  previously  disclosed  business  combination  between 
Talos  Energy  LLC  and  Stone  Energy  Corporation  (“Stone”)  that  occurred  on  May  10,  2018,  pursuant  to  which 
Talos Energy LLC and Stone became indirect wholly owned subsidiaries of Talos Energy Inc. 

Talos Energy LLC

Talos Energy LLC was formed in 2011 and commenced commercial operations on February 6, 2013. Prior to 
February 6, 2013, Talos Energy LLC had incurred certain general and administrative expenses associated with the 
start-up of its operations.  

On February 3, 2012, Talos Energy LLC completed a transaction with funds and other alternative investment 
vehicles managed by Apollo Management VII, L.P. and Apollo Commodities Management, L.P., with respect to 
Series  I  (“Apollo  Funds”),  and  entities  controlled  by  or  affiliated  with  Riverstone  Energy  Partners  V,  L.P. 
(“Riverstone Funds”, and together with the Apollo Funds, the “Sponsors”) and members of management pursuant 
to which the Company received a private equity capital commitment.

Stone Combination

On  May  10,  2018  (the  “Closing  Date”),  the  Company  (f/k/a  Sailfish  Energy  Holdings  Corporation) 
consummated  the  transactions  contemplated  by  that  certain  Transaction  Agreement,  dated  as  of  November  21, 
2017  (the  “Transaction  Agreement”),  by  and  among  Stone,  the  Company,  Sailfish  Merger  Sub  Corporation 
(“Merger  Sub”),  Talos  Energy  LLC  and  Talos  Production  LLC,  pursuant  to  which,  among  other  items,  each  of 
Stone,  Talos  Production  LLC  and  Talos  Energy  LLC  became  wholly-owned  subsidiaries  of  the  Company  (the 
“Stone Combination”). Prior to the Closing Date, the Company did not conduct any material activities other than 
those incident to its formation and the matters contemplated by the Transaction Agreement. 

On  Closing  Date,  the  following  transactions,  among  others,  occurred:  (i) Stone  underwent  a  reorganization 
pursuant to which Merger Sub merged with and into Stone, with Stone continuing as the surviving corporation and 
a  direct  wholly-owned  subsidiary  of  the  Company  (the  “Merger”)  and  each  share  of  Stone’s  common  stock 
outstanding immediately prior to the Merger (other than treasury shares held by Stone, which were cancelled for no 
consideration) was converted into the right to receive one share of the Company’s common stock, par value $0.01 
(the “Common Stock”) and (ii) the Sponsors contributed all of the equity interests in Talos Production LLC (which 
at  that  time  owned  100%  of  the  equity  interests  in  Talos  Energy  LLC)  to  the  Company  in  exchange  for  an 
aggregate of 31,244,085 shares of Common Stock (the “Sponsor Equity Exchange”).

Concurrently  with  the  consummation  of  the  Transaction  Agreement,  the  Company  consummated  the 
transactions  contemplated  by  that  certain  Exchange  Agreement,  dated  as  of  November 21,  2017  (the  “Exchange 
Agreement”), among the Company, Stone, the Talos Issuers (defined below), the various lenders and noteholders 
of the Talos Issuers listed therein, certain funds controlled by Franklin Advisers, Inc. (“Franklin”) (such controlled 
noteholders, the “Franklin Noteholders”), and certain clients of MacKay Shields LLC (“MacKay Shields”) (such 
noteholders, the “MacKay Noteholders”), pursuant to which (i) the Apollo Funds and Riverstone Funds contributed 
$102.0 million in aggregate principal amount of 9.75% Senior Notes due 2022 (“9.75% Senior Notes”) issued by 
Talos  Production  LLC  and  Talos  Production  Finance,  Inc.  (together,  the  “Talos  Issuers”)  to  the  Company  in 
exchange for an aggregate of 2,874,049 shares of Common Stock (the “Sponsor Debt Exchange”); (ii) the holders 
of second lien bridge loans (“11.00% Bridge Loans”) issued by the Talos Issuers exchanged such 11.00% Bridge 

F-8

6696_10K.pdf

Loans for $172.0 million aggregate principal amount of 11.00% Second-Priority Senior Secured Notes due 2022 of 
the  Talos  Issuers  (“11.00%  Senior  Secured  Notes”)  and  (iii) Franklin  Noteholders  and  MacKay  Noteholders 
exchanged their 7.50% Senior Secured Notes due 2022 issued by Stone (“7.50% Stone Senior Notes”) for $137.4 
million aggregate principal amount of 11.00% Senior Secured Notes.

Substantially  concurrent  therewith,  the  Company  consummated  an  exchange  offer  and  consent  solicitation, 
pursuant to which the holders of the 7.50% Stone Senior Notes, excluding the 7.50% Stone Senior Notes held by 
the  Franklin  Noteholders  and  the  MacKay  Noteholders,  exchanged  their  7.50%  Stone  Senior  Notes  for  11.00% 
Senior  Secured  Notes  and  a  cash  payment,  and  a  solicitation  of  consents  to  proposed  amendments  to  the  7.50% 
Stone Senior Notes. Approximately $81.5 million in aggregate principal amount of the 7.50% Stone Senior Notes 
were validly tendered, and approximately $6.1 million in aggregate principal amount of 7.50% Stone Senior Notes 
remained outstanding as of the Closing Date.

As a result of the closing of the transactions contemplated by the Transaction Agreement and the Exchange 
Agreement  (the  “Transactions”)  the  former  stakeholders  of  Talos  Energy  LLC  held  approximately  63%  of  the 
Company’s  outstanding  Common  Stock  and  the  former  stockholders  of  Stone  held  approximately  37%  of  the 
Company’s outstanding Common Stock as of the Closing Date.

Basis of Presentation and Consolidation

The consolidated financial statements have been prepared in accordance with accounting principles generally 
accepted  in  the  United  States  of  America  (“GAAP”)  and  include  each  subsidiary  from  the  date  of  inception.  All 
intercompany  transactions  have  been  eliminated.  All  adjustments  are  of  a  normal,  recurring  nature  and  are 
necessary to fairly present the financial position, results of operations and cash flows for the periods are reflected 
herein. The Company has evaluated subsequent events through the date the consolidated financial statements were 
issued.

Talos  Energy  LLC  was  considered  the  accounting  acquirer  in  the  Stone  Combination  under  GAAP. 
Accordingly,  the  historical  financial  and  operating  data  of  Talos  Energy  Inc.,  which  covers  periods  prior  to  the 
Closing Date, reflects the assets, liabilities and results of operations of Talos Energy LLC and does not reflect the 
assets,  liabilities  and  results  of  operations  of  Stone.  For  the  periods  prior  to  May  10,  2018,  the  Company 
retrospectively adjusted its Statement of Changes in Stockholders’ Equity and the weighted average shares used in 
determining  earnings  per  share  to  reflect  the  number  of  shares  Talos  Energy  LLC  received  in  the  Stone 
Combination. Beginning on May 10, 2018, common stock is presented to reflect the legal capital of Talos Energy 
Inc.

The preparation of financial statements in conformity with GAAP requires management to make estimates 
and  assumptions  that  affect  the  reported  amounts  of  assets  and  liabilities  and  disclosure  of  contingent  assets  and 
liabilities  as  of  the  date  of  the  financial  statements,  the  reported  amounts  of  revenues  and  expenses  during  the 
reporting periods and the reported amounts of proved oil and natural gas reserves. Actual results could differ from 
those estimates.

The  Company  has  one  reportable  segment,  which  is  the  exploration  and  production  of  oil  and  natural  gas. 
Substantially  all  the  Company’s  long-lived  assets,  proved  reserves  and  production  sales  are  related  to  the 
Company’s operations in the United States.

Recently Adopted Accounting Standards

Revenue Recognition

On January 1, 2018, the Company adopted Accounting Standards Codification (“ASC”) 606, Revenue from 
Contracts with Customers using the modified retrospective approach. ASC 606 supersedes the revenue recognition 
requirements in Topic 615, Revenue Recognition, and industry-specific guidance in Subtopic 932-605, Extractive 
Activities – Oil and Gas – Revenue Recognition. The new standard includes a five-step revenue recognition model 
to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the 
Company expects to be entitled in exchange for these goods and services. 

The Company records revenues from the sale of oil, natural gas and NGLs based on quantities of production 
sold  to  purchasers  under  short-term  contracts  (less  than  twelve  months)  at  market  prices  when  delivery  to  the 
customer has occurred, title has transferred, prices are fixed and determinable and collection is reasonably assured. 
This occurs when production has been delivered to a pipeline or when a barge lifting has occurred.

F-9

6696_10K.pdf

The Company applied the practical expedient in ASC 606 exempting the disclosure of the transaction price 
allocated  to  remaining  performance  obligations  if  the  variable  consideration  is  allocated  entirely  to  a  wholly 
unsatisfied  performance  obligation.  Each  unit  of  product  typically  represents  a  separate  performance  obligation, 
therefore,  future  volumes  are  wholly  unsatisfied  and  disclosure  of  the  transaction  price  allocated  to  remaining 
performance obligations is not required.

Gas Imbalances. Under previous accounting guidance, the Company used the entitlement method to account 
for  sales  and  production.  Under  the  entitlement  method,  revenue  was  recorded  based  on  the  Company’s  entitled 
share  of  production  with  any  difference  recorded  as  an  imbalance  on  the  consolidated  balance  sheet.  Upon  the 
adoption of ASC 606, revenues are recorded based on the actual sales volumes sold to purchasers. An imbalance 
receivable  or  payable  is  recorded  only  to  the  extent  the  imbalance  is  in  excess  of  its  share  of  remaining  proved 
developed reserves in an underlying property. The change in accounting method from the entitlements method to 
the  sales  method  resulted  in  an  immaterial  cumulative-effect  adjustment  to  stockholders’  deficit  on  the  date  of 
adoption.

Production  Handling  Fees.  Under  previous  accounting  guidance,  the  Company  presented  certain 
reimbursements for costs from certain third parties as other revenue on the consolidated statement of operations. 
Upon the adoption of ASC 606, the reimbursements are presented as a reduction of direct lease operating expense 
on  the  consolidated  statement  of  operations.  The  impact  of  the  reclassification  for  the  year  ended  December 31, 
2018 was immaterial.

Recently Issued Accounting Standards

Leases.  In  February  2016,  the  FASB  issued  ASU  2016-02,  Leases  (Topic  842).  This  ASU  supersedes  the 
lease requirements in Topic 840, Leases, and requires that a lessee recognize a right-of-use asset and lease liability 
for leases that do not meet the definition of a short-term lease. The right-of-use asset and lease liability are to be 
measured  on  the  balance  sheet  at  the  present  value  of  the  lease  payments.  For  income  statement  purposes,  ASU 
2016-02 retains a dual model requiring leases to be classified as either operating or finance within the Company’s 
consolidated  statements  of  operations.  Lease  costs  for  operating  leases  are  recognized  as  a  single  lease  cost, 
calculated so that the cost of the lease is allocated over the lease term on a straight-line basis. For finance leases, 
interest  expense  is  recognized  on  the  lease  liability  separately  from  amortization  of  the  right-to-use  asset.  ASU 
2016-02 does not apply to leases for oil and natural gas properties, but does apply to equipment used to explore and 
develop  oil  and  natural  gas  reserves.  This  ASU  is  effective  for  fiscal  years  beginning  after  December  15,  2018, 
including the first quarter of 2019. The Company will adopt this standard using the modified retrospective method 
applied  to  all  leases  that  exist  on  January  1,  2019.  Talos  made  certain  elections  allowing  the  Company  not  to 
reassess contracts that commenced prior to adoption and to not recognize right-of-use assets or lease liabilities for 
short-term  leases.  Upon  adoption,  the  Company  expects  the  right-to-use  asset  and  lease  liability  reported  on  the 
consolidated balance sheet to be material. The Company is finalizing the implementation of the changes to business 
processes, systems and controls to support accounting and disclosure requirements of this ASU.

Note 2 — Summary of Significant Accounting Policies

Below are the Company’s significant accounting policies.

Cash and Cash Equivalents

The Company presents cash as cash and cash equivalents on the Company’s consolidated balance sheets. The 
Company considers all cash, money market funds and highly liquid investments with an original maturity of three 
months or less as cash and cash equivalents. Cash and cash equivalents are carried at cost, which approximates fair 
value.

Accounts Receivable and Allowance for Uncollectible Accounts

Accounts  receivable  are  stated  at  the  historical  carrying  amount  net  of  an  allowance  for  uncollectible 
accounts of $8.7 million at December 31, 2018 and $5.9 million at December 31, 2017. The Company establishes 
provisions for losses on accounts receivable with other parties if it believes that it will not collect all or part of the 
outstanding  balance.  On  a  quarterly  basis,  the  Company  reviews  collectability  and  establishes  or  adjusts  the 
Company’s allowance as necessary using the specific identification method. 

F-10

6696_10K.pdf

Prepaid Assets

Prepaid  assets  primarily  represent  deposits  with  the  Office  of  Natural  Resources  Revenue  (“ONRR”).  The 
deposits  are  the  Company’s  estimated  ONRR  royalties  payable  within  thirty  days  of  the  production  rate.  On  a 
monthly basis the Company adjusts the deposit based on actual royalty payments remitted to the ONRR.

Revenue Recognition

Upon  the  adoption  of  ASC  606,  revenues  are  recorded  based  from  the  sale  of  oil,  natural  gas  and  NGL 

quantities sold to purchasers. See Note 1 — Formation and Basis of Presentation for additional information.

Accounting for Oil and Natural Gas Activities

The Company follows the full cost method of accounting for oil and natural gas exploration and development 
activities.  Under  the  full  cost  method,  substantially  all  costs  incurred  in  connection  with  the  acquisition, 
development and exploration of oil and natural gas reserves are capitalized. These capitalized amounts include the 
internal  costs  directly  related  to  acquisition,  development  and  exploration  activities,  asset  retirement  costs  and 
capitalized interest. Under the full cost method, dry hole costs and geological and geophysical costs are capitalized 
into the full cost pool, which is subject to amortization and assessed for impairment on a quarterly basis through a 
ceiling test calculation as discussed below. In August 2016, the Company entered into a capital lease for the use of 
the  Helix  Producer  I  (“HP-I”),  a  dynamically  positioned  floating  production  facility  that  interconnects  with  the 
Phoenix  Field  through  a  production  buoy,  and  recorded  a  $124.3  million  capital  lease  asset.  Since  the  HP-I  is 
utilized in the Company’s oil and natural gas development activities, the asset is included within proved property 
and subject to the ceiling test calculation described below. Due to the inclusion within proved properties, the HP-I 
is depleted as part of the full cost pool. See Note 11 — Commitments and Contingencies for additional information.

Capitalized costs associated with proved reserves are amortized on a country by country basis over the life of 
the  total  proved  reserves  using  the  unit  of  production  method,  computed  quarterly.  Conversely,  capitalized  costs 
associated  with  unproved  properties  and  related  geological  and  geophysical  costs,  exploration  wells  currently 
drilling and capitalized interest are initially excluded from the amortizable base. The Company transfers unproved 
property  costs  into  the  amortizable  base  when  properties  are  determined  to  have  proved  reserves  or  when  the 
Company  has  completed  an  unproved  properties  evaluation  resulting  in  an  impairment.  The  Company  evaluates 
each of these unproved properties individually for impairment at least quarterly. Additionally, the amortizable base 
includes  future  development  costs,  dismantlement,  restoration  and  abandonment  costs,  net  of  estimated  salvage 
values, and geological and geophysical costs incurred that cannot be associated with specific unproved properties 
or prospects in which the Company owns a direct interest. 

The Company’s capitalized costs are limited to a ceiling based on the present value of future net revenues 
from proved reserves, computed using a discount factor of 10 percent, plus the lower of cost or estimated fair value 
of unproved oil and natural gas properties not being amortized less the related tax effects. Any costs in excess of 
the  ceiling  are  recognized  as  a  non-cash  impairment  expense  on  the  consolidated  statement  of  operations  and  an 
increase  to  accumulated  depreciation,  depletion  and  amortization  on  the  Company’s  consolidated  balance  sheets. 
The  expense  may  not  be  reversed  in  future  periods,  even  though  higher  oil,  natural  gas  and  NGL  prices  may 
subsequently increase the ceiling. The Company performs this ceiling test calculation each quarter. In accordance 
with  the  SEC  rules  and  regulations,  the  Company  utilize  SEC  Pricing  when  performing  the  ceiling  test.  The 
Company also holds prices and costs constant over the life of the reserves, even though actual prices and costs of 
oil and natural gas are often volatile and may change from period to period. The ceiling test computation did not 
result in a write-down of the Company’s oil and natural gas properties during the years ended December 31, 2018, 
2017 and 2016.

Under the full cost method of accounting for oil and natural gas operations, assets whose costs are currently 
being  depreciated,  depleted  or  amortized  are  assets  in  use  in  the  earnings  activities  of  the  enterprise  and  do  not 
qualify  for  capitalization  of  interest  cost.  Investments  in  unproved  properties  for  which  exploration  and 
development  activities  are  in  progress  and  other  major  development  projects  that  are  not  being  currently 
depreciated, depleted or amortized are assets qualifying for capitalization of interest costs. 

When the Company sells or conveys interests in oil and natural gas properties, the Company reduces its oil 
and  natural  gas  reserves  for  the  amount  attributable  to  the  sold  or  conveyed  interest.  The  Company  treats  sales 
proceeds  on  non-significant  sales  as  reductions  to  the  cost  of  the  Company’s  oil  and  natural  gas  properties.  The 
Company  does  not  recognize  a  gain  or  loss  on  sales  of  oil  and  natural  gas  properties,  unless  those  sales  would 
significantly alter the relationship between capitalized costs and proved reserves. 

F-11

6696_10K.pdf

The Company recognizes transportation costs as a component of direct lease operating expense when it is the 
shipper  of  the  product.  Such  costs  were  $12.5  million,  $10.3  million  and  $9.1  million  in  the  years  ended 
December 31, 2018, 2017 and 2016, respectively.

Other Property and Equipment

Other property and equipment is recorded at cost and consists primarily of leasehold improvements, office 
furniture  and  fixtures,  computer  hardware  and  software.  Acquisitions,  renewals  and  betterments  are  capitalized; 
maintenance  and  repairs  are  expensed  as  incurred.  Depreciation  is  provided  using  the  straight-line  method  over 
estimated useful lives of three to ten years. 

Other Well Equipment Inventory

Other well equipment inventory primarily represents the cost of equipment to be used in the Company’s oil 
and natural gas drilling and development activities such as drilling pipe, tubulars and certain wellhead equipment. 
When this inventory is supplied to wells, the cost of this inventory is capitalized in oil and gas properties, and if 
such  property  is  jointly  owned,  the  proportionate  costs  will  be  reimbursed  by  third  party  participants.  The 
Company’s  inventory  is  stated  at  the  lower  of  cost  or  net  realizable  value.  The  Company  recorded  $0.2  million, 
$0.3  million,  $0.2  million  of  impairment  to  adjust  inventory  to  net  realizable  value,  which  was  expensed  and 
reflected  in  workover/maintenance  expense,  during  the  years  ended  December 31,  2018,  2017  and  2016, 
respectively.

Fair Value Measure of Financial Instruments

Financial  instruments  generally  consist  of  cash  and  cash  equivalents,  restricted  cash,  accounts  receivable, 
commodity  derivatives,  accounts  payable  and  debt.  The  carrying  amount  of  cash  and  cash  equivalents,  restricted 
cash,  accounts  receivable  and  accounts  payable  approximates  fair  value  due  to  the  highly  liquid  nature  of  these 
instruments. 

Current fair value accounting standards define fair value, establish a consistent framework for measuring fair 
value and stipulate the related disclosure requirements for each major asset and liability category measured at fair 
value on either a recurring or nonrecurring basis. These standards also clarify fair value is an exit price, presenting 
the amount that would be received to sell an asset or paid to transfer a liability, in an orderly transaction between 
market participants. The Company follows a three-level hierarchy, prioritizing and defining the types of inputs used 
to measure fair value depending on the degree to which they are observable as follows: 

Level 1 – Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities 
in active markets.

Level 2 – Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active 
markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially 
the full term of the financial statement.

Level 3 – Inputs to the valuation methodology are unobservable (little or no market data), which require the 
reporting entity to develop its own assumptions, and are significant to the fair value measurement.

Assets  and  liabilities  measured  at  fair  value  are  based  on  one  or  more  of  three  valuation  techniques.  The 

valuation techniques are as follows:

Market  Approach –  Prices  and  other  relevant  information  generated  by  market  transactions  involving 
identical or comparable assets or liabilities.

Cost  Approach –  Amount  that  would  be  required  to  replace  the  service  capacity  of  an  asset  (replacement 
cost).

Income Approach – Techniques to convert expected future cash flows to a single present value amount based 
on market expectations (including present value techniques, option-pricing and excess earnings models).

Authoritative guidance on financial instruments requires certain fair value disclosures to be presented. The 
estimated  fair  value  amounts  have  been  determined  using  available  market  information  and  valuation 
methodologies. Considerable judgment is required in interpreting market data to develop the estimates of fair value. 
The use of different assumptions or valuation methodologies may have a material effect on the estimated fair value 
amounts.

Asset Retirement Obligations

The Company is required to record its asset retirement obligations at fair value in the period such obligations 
are incurred with the associated asset retirement costs being capitalized as part of the carrying cost of the asset. The 
Company’s asset retirement obligations consist of estimated costs for dismantlement, removal, site reclamation and 
similar activities associated with the Company’s oil and natural gas properties. The estimate of the asset retirement 
cost is determined, inflated to an estimated future value using a ten year average of the Consumer Price Index and 
discounted  to  present  value  using  the  Company’s  credit-adjusted  risk-free  rate.  Accretion  of  the  liability  is 
recognized for changes in the value of the liability as a result of the passage of time over the estimated productive 
life of the related assets as the discounted liabilities are accreted to their expected settlement values.

Price Risk Management Activities

The Company uses commodity price derivatives to manage fluctuating oil and natural gas market risks. The 
Company  periodically  enters  into  commodity  derivative  contracts,  which  may  require  payments  to  (or  receipts 
from) counterparties based on the differential between a fixed price and a variable price for a fixed quantity of oil 
or natural gas without the exchange of underlying volumes.

Commodity derivatives are recorded on the consolidated balance sheets at fair value with settlements of such 
contracts and changes in the unrealized fair value recorded in earnings each period. Realized gains and losses on 
the settlement of commodity derivatives and changes in their unrealized gains and losses are reported in price risk 
management activities income (expense) in the consolidated statements of operations. The Company classifies cash 
flows related to derivative contracts based on the nature and purpose of the derivative. As the derivative cash flows 
are considered an integral part of the Company’s oil and natural gas operations, they are classified as cash flows 
from operating activities. The Company does not enter into derivative agreements for trading or other speculative 
purposes.

The  commodity  derivative’s  fair  value  reflects  the  Company’s  best  estimate  with  priority  based  upon 
exchange  or  over-the-counter  quotations.  Quoted  valuations  may  not  be  available  due  to  location  differences  or 
terms  that  extend  beyond  the  period  for  which  quotations  are  available.  Where  quotes  are  not  available,  the 
Company then utilizes other valuation techniques or models to estimate market values. These modeling techniques 
require  the  Company  to  make  estimations  of  future  prices,  price  correlation,  market  volatility  and  liquidity.  The 
Company’s actual results may differ from its estimates, and these differences can be favorable or unfavorable. 

Income Taxes

Prior to the Stone Combination, Talos Energy LLC was a partnership for U.S. federal income tax purposes 
and  was  not  subject  to  U.S.  federal  income  tax  or  state  income  tax  (in  most  states)  at  the  entity  level.   As  such, 
Talos  Energy  LLC  did  not  recognize  U.S.  federal  income  tax  expense  or  state  income  tax  expense  in  most 
states.  In connection with the Stone Combination, Talos Energy LLC was contributed to the Company, which is 
subject to U.S. federal and state income taxes. The Company records current income taxes based on estimates of 
current taxable income and provides for deferred income taxes to reflect estimated future income tax payments and 
receipts. Changes in tax laws are recorded in the period they are enacted. Deferred taxes represent the tax impacts 
of  differences  between  the  financial  statement  and  tax  bases  of  assets  and  liabilities  and  carryovers  at  each  year 
end. The Company classifies all deferred tax assets and liabilities, along with any related valuation allowance, as 
long-term on the consolidated balance sheets. 

The  realization  of  deferred  tax  assets  depends  on  recognition  of  sufficient  future  taxable  income  during 
periods  in  which  those  temporary  differences  are  deductible.  The  Company  reduces  deferred  tax  assets  by  a 
valuation allowance when, based on estimates, it is more likely than not that a portion of those assets will not be 
realized  in  a  future  period.  The  deferred  tax  asset  estimates  are  subject  to  revision,  either  up  or  down,  in  future 
periods  based  on  new  facts  or  circumstances.  In  evaluating  the  Company’s  valuation  allowances,  the  Company 
considers cumulative book losses, the reversal of existing temporary differences, the existence of taxable income in 
carryback years, tax planning strategies and future taxable income for each of its taxable jurisdictions, the latter two 
of  which  involve  the  exercise  of  significant  judgment.  Changes  to  the  Company’s  valuation  allowances  could 
materially impact its results of operations.

The Company’s policy is to classify interest and penalties associated with underpayment of income taxes as 

interest expense and general and administrative expense, respectively.

Earnings Per Share 

Basic  net  income  per  common  share  (“EPS”)  is  computed  by  dividing  net  income  (loss)  by  the  weighted 
average  number of shares  of  common  stock  outstanding  during  the  period. Except  when  the  effect  would  be 
antidilutive, diluted EPS includes the impact of restricted stock units (“RSUs”), performance share units (“PSUs”) 
and outstanding warrants. See Note 9 — Earnings Per Share for additional information.

Share-Based Compensation 

Certain of the Company’s employees participate in its equity based compensation. The Company measures 
all  employee  equity  based  compensation  awards  at  fair  value  as  calculated  using  an  option  pricing  method  for 
valuing  such  securities  on  the  date  awards  are  granted  to  its  employees  and  recognize  compensation  cost  on  a 
straight-line basis in the Company’s financial statements over the vesting period of each grant according to ASC 
718, Compensation—Stock Compensation. 

During 2018, the Company issued RSUs and PSUs to certain employees and non-employee directors.  The 
fair value of the stock-based awards is determined at the date of grant and is not remeasured for awards classified 
as  equity,  but  is  remeasured  at  each  reporting  period  for  awards  classified  as  a  liability.  The  Company  records 
share-based compensation, net of actual forfeitures, for the RSUs and PSUs in general and administrative expense 
on  the  consolidated  statement  of  operations,  net  of  amounts  capitalized  to  oil  and  gas  properties.  See  Note  7  — 
Employee Benefits Plans and Share-Based Compensation for additional information.

RSUs. Share-based compensation is based on the market price of the Company’s Common Stock on the grant 
date  and  recognized  over  the  vesting  period  using  the  straight-line  method  as  the  requisite  service  period  is 
fulfilled. 

PSUs.  Share-based  compensation  is  based  on  the  grant  date  fair  value  determined  using  a  Monte  Carlo 
valuation model and recognized over the vesting period using the straight-line method. Estimates used in the Monte 
Carlo  valuation  model  are  considered  highly-complex  and  subjective.  The  number  of  shares  of  Common  Stock 
issuable  upon  vesting  ranges  from  zero  to  200%  of  the  number  of  PSUs  granted  based  on  the  Company’s  total 
shareholder  return  (“TSR”)  relative  to  the  TSR  achieved  by  a  specified  industry  peer  group.  Share-based 
compensation related to PSUs is recognized as the requisite service period is fulfilled, even if the market condition 
is not achieved.

Concentration of Credit Risk

Consisting  principally  of  cash  and  cash  equivalents,  restricted  cash,  accounts  receivable  and  commodity 

derivatives, the Company is subject to concentrated financial instruments credit risk.

Cash  and  cash  equivalents  and  restricted  cash  balances  are  maintained  in  financial  institutions,  which  at 
times, exceed federally insured limits. The Company monitors the financial condition of these institutions and has 
not experienced losses on these accounts. 

Commodity derivatives are entered into with registered swap dealers, the majority of which participate in the 
Company’s senior reserve-based revolving credit facility (the “Bank Credit Facility”). The Company monitors the 
financial  condition  of  these  institutions  and  has  not  experienced  losses  due  to  counterparty  default  on  these 
instruments.

The  Company  markets  substantially  all  of  its  oil  and  natural  gas  production,  and  all  of  its  revenues  are 
attributable to the U.S. The majority of the Company’s oil, natural gas and NGL production is sold to customers 
under  short-term  (less  than  12  months)  contracts  at  market-based  prices.  The  Company’s  customers  consist 
primarily of major oil and natural gas companies, well-established oil and pipeline companies and independent oil 
and gas producers and suppliers. The Company performs ongoing credit evaluations of its customers and provide 
allowances  for  probable  credit  losses  when  necessary.  The  percent  of  consolidated  revenue  of  major  customers, 
those whose total represented 10% or more of the Company’s oil, natural gas and NGL revenues, was as follows:

Shell Trading (US) Company
Phillips 66
Chevron U.S.A Inc.

The loss of a major customer could have material adverse effect on the Company in the short term. However, 
the Company believes it would be able to obtain other customers to market its oil, natural gas and NGL production.

Note 3 — Acquisitions

Business Combination

Combination Between Talos Energy LLC and Stone Energy Corporation

The  Stone  Combination  qualified  as  a  business  combination  and  was  accounted  for  under  the  acquisition 
method  of  accounting,  which  requires,  among  other  items,  that  assets  acquired  and  liabilities  assumed  be 
recognized on the consolidated balance sheet at their fair values as of the acquisition date, May 10, 2018. The fair 
value measurements of the oil and natural gas properties acquired and asset retirement obligations assumed were 
derived utilizing an income approach and based, in part, on significant inputs not observable in the market. These 
inputs represent Level 3 measurements in the fair value hierarchy and include, but are not limited to, estimates of 
reserves,  future  operating  and  development  costs,  future  commodity  prices,  estimated  future  cash  flows  and 
appropriate discount rates. These inputs required significant judgments and estimates at the time of the valuation. 

On May 10, 2018, the Company consummated the Transactions contemplated by the Transaction Agreement 
and Exchange Agreement, pursuant to which, among other things, Talos Energy LLC and Stone became wholly-
owned subsidiaries of the Company. The combination was executed as an all-stock transaction whereby the former 
stakeholders of Talos Energy LLC held approximately 63% of the Company’s outstanding Common Stock and the 
former  stockholders  of  Stone  held  approximately  37%  of  the  Company’s  outstanding  Common  Stock  as  of  the 
Closing Date. 

The  purchase  price  of  $732.0  million  is  based  on  the  closing  price  of  Stone  common  stock  and  common 
warrants immediately prior to closing. The following table summarizes the purchase price (in thousands, except per 
share data): 

Stone Energy common stock - issued and outstanding as of May 9, 2018

The Company incurred approximately $88.6 million of transaction related costs, of which, $32.5 million was 
expensed  and  reflected  in  general  and  administrative  expense  on  the  consolidated  statement  of  operations.  The 
remaining  $56.1  million  was  the  result  of  (i)  $9.3  million  in  work  fees  paid  to  holders  of  the  11.00%  Senior 
Secured Notes reflected as a debt discount reducing long-term debt on the consolidated balance sheet and (ii) $46.8 
million in fees for seismic use agreements for change in control provisions and reflected in proved properties on the 
consolidated balance sheet.

While the Company has substantially completed the determination of the fair values of the assets acquired 
and  liabilities  assumed,  the  Company  is  still  finalizing  the  fair  value  analysis  related  to  oil  and  natural  gas 
properties  acquired  by  Stone  prior  to  Closing.  The  Company  anticipates  finalizing  the  determination  of  the  fair 
values by March 31, 2019.

During the third and fourth quarters of 2018, certain adjustments were recorded to reflect new information 
obtained subsequent to recording the preliminary allocation of the purchase price. Income tax receivables decreased 
by $5.5 million, trade receivables increased by $1.0 million, other long-term liabilities increased by $2.7 million 
and unproved properties increased by $7.2 million. Had these adjustments been recorded as of the acquisition date, 
May 10, 2018, there would have been no corresponding impact to net income subsequent to the acquisition. These 
adjustments are reflected in the preliminary purchase price allocation table below.

Asset Acquisitions

Each of the acquisitions below qualified as an asset acquisition that requires, among other items, that the cost 
of the assets acquired and liabilities assumed to be recognized on the balance sheet by allocating the asset cost on a 
relative  fair  value  basis.  The  fair  value  measurements  of  the  oil  and  natural  gas  properties  acquired  and  asset 
retirement obligations assumed were derived utilizing an income approach and based, in part, on significant inputs 
not observable in the market. These inputs represent Level 3 measurements in the fair value hierarchy and include, 
but  are  not  limited  to,  estimates  of  reserves,  future  operating  and  development  costs,  future  commodity  prices, 
estimated  future  cash  flows  and  appropriate  discount  rates.  These  inputs  required  significant  judgments  and 
estimates  by  the  Company’s  management  at  the  time  of  the  valuation.  Transaction  costs  incurred  on  an  asset 
acquisition are capitalized as a component of the assets acquired and any contingent consideration is recognized as 
the contingency is resolved. 

Acquisition of Whistler Energy II, LLC 

On August 31, 2018, the Company completed the acquisition of all the issued and outstanding membership 
interests of Whistler Energy II, LLC (“Whistler”) from Whistler Energy II Holdco, LLC, an affiliate of the Apollo 
Funds, for $52.6 million ($14.8 million, net of $37.8 million of cash acquired). The $37.8 million of cash acquired 
consists  of  $30.8  million  of  cash  collateral  posted  by  Whistler  and  released  by  third  party  surety  companies  at 
closing  and  $7.0  million  of  cash  on  hand  for  working  capital  purposes.  Through  the  acquisition,  the  Company 
acquired all of Whistler’s oil and natural gas assets located in Green Canyon Block 18, Green Canyon Block 69 
and Ewing Bank Block 988, including a fixed production platform on Green Canyon Block 18. The Company also 
assumed  the  associated  asset  retirement  obligations.  The  Company  refers  to  the  acquisition  of  all  the  issued  and 
outstanding membership interests as the “Whistler Acquisition.”

Acquisition of Additional Working Interest in the Phoenix Field 

On  December  20,  2016,  the  Company  purchased  an  additional  15%  working  interest  in  the  Phoenix  Field 
from Sojitz Energy Venture Inc. (“Sojitz”) for approximately $85.8 million in cash and the assumption of certain 
asset  retirement  obligations,  subject  to  customary  post-closing  adjustments.  The  purchase  price  was  funded  by  a 
$93.8 million ($91.9 million, net of $1.9 million of transaction fees) contribution from the Sponsors. Additionally, 
the  Company  entered  into  a  contingent  consideration  arrangement  in  the  form  of  an  earn-out  equal  to  5%  of  the 
acquired property’s monthly net profit if its realized oil price is greater than $65.00 per Bbl in a given month. The 
maximum payout under the earn-out is $10.0 million and it has an indefinite life pursuant to the purchase and sale 
agreement. The Company refers to the acquisition of assets from Sojitz as the “Sojitz Acquisition.”

Through  December  31,  2017,  the  Company  recorded  $2.5  million  in  post-closing  adjustments  related  to 
activity between the effective date and closing date of the acquisition. The following table presents the allocation of

Proved Properties. The Company’s interests in oil and natural gas proved properties are located in the United 
States,  primarily  in  the  Gulf  of  Mexico  deep  and  shallow  waters.  The  Company  follows  the  full  cost  method  of 
accounting for its oil and natural gas exploration and development activities. In August 2016, the Company entered 
into  a  capital  lease  for  the  use  of  the  HP-I  and  recorded  a  $124.3  million  capital  lease  asset.  Since  the  HP-I  is 
utilized in its oil and natural gas development activities, the asset is included within proved property, subject to the 
ceiling test calculation described below, and is depleted as part of the full cost pool. 

Pursuant  to  SEC  Regulation  S-X,  Rule  4-10,  under  the  full  cost  method  of  accounting,  the  Company’s 
capitalized oil and natural gas costs are limited to a ceiling based on the present value of future net revenues from 
proved  reserves,  computed  using  a  discount  factor  of  10%,  plus  the  lower  of  cost  or  estimated  fair  value  of 
unproved oil and natural gas properties not being amortized less the related tax effects. The Company performs this 
ceiling test calculation each quarter utilizing SEC pricing. During 2018, 2017 and 2016, the Company’s ceiling test 
computations did not result in a write-down of its U.S. oil and natural gas properties. At December 31, 2018, its 
ceiling  test  computation  was  based  on  SEC  pricing  of  $69.42  per  Bbl  of  oil,  $3.08  per  Mcf  of  natural  gas  and 
$29.50 per Bbl of NGLs.

Unproved  Properties.  Unproved  capitalized  costs  of  oil  and  natural  gas  properties  excluded  from 
amortization  relate  to  unevaluated  properties  associated  with  acquisitions,  leases  awarded  in  the  U.S.  Gulf  of 
Mexico federal lease sales, certain geological and geophysical costs, costs associated with certain exploratory wells 
in progress and capitalized interest. Unproved properties also include costs associated with the two blocks (Block 2 
and Block 7) awarded on September 4, 2015 to the Company together with Sierra Oil & Gas S. de R.L de C.V. 
(“Sierra”)  and  Premier  Oil  Plc  (“Premier”),  the  (“Consortium”),  located  in  the  shallow  waters  off  the  coast  of 
Mexico’s Veracruz and Tabasco states, by the National Hydrocarbons Commission (“CNH”), Mexico’s upstream 
regulator.

In September 2018, the Company entered into a transaction (the “Hokchi Cross Assignment”) with Hokchi 
Energy, S.A. de C.V. (“Hokchi”), a subsidiary of Pan American Energy (“PAE”), to cross assign 25% participation 
interests (“PIs”) in Block 2 and Block 31. The Company’s assignment of a 25% PI in Block 2 to Hokchi closed on 
December  21,  2018,  and  Hokchi  has  assumed  operator  responsibilities  with  respect  to  Block  2.  Hokchi’s 
assignment  of  Block  31  to  the  Company  will  be  completed  upon  final  approval  by  the  CNH  subsequent  to 
December 31, 2018. In addition, Premier exercised its option to reduce its PI in Block 2 to zero and assign a 5% PI 
to each of Sierra and the Company. Such assignment is also subject to CNH’s approval which had not occurred as 
of  December  31,  2018.  Upon  completion  of  the  Hokchi  Cross  Assignment  and  Premier’s  option  exercise,  the 
Company will own a 25% PI in each of Block 2 and Block 31, and Hokchi will be the operator of both blocks. 

The  following  table  sets  forth  a  summary  of  the  Company’s  oil  and  natural  gas  property  costs  not  being

The excluded costs will be included in the amortization base as properties are evaluated and proved reserves 

are established or impairment is determined. The Company expects this process to occur over the next five years.

Capitalized Overhead. General and administrative expense in the Company’s financial statements is reflected 
net  of  capitalized  overhead.  The  Company  capitalizes  overhead  costs  that  are  directly  related  to  exploration, 
acquisition  and  development  activities.  Capitalized  overhead  for  the  years  ended  December 31,  2018,  2017  and 
2016 was $21.9 million, $13.7 million and $12.5 million, respectively. 

Asset  Retirement  Obligations.  The  Company  has  obligations  associated  with  the  retirement  of  its  oil  and 
natural gas wells and related infrastructure. The Company has obligations to plug wells when production on those 
wells  is  exhausted,  when  the  Company  no  longer  plans  to  use  them  or  when  the  Company  abandons  them.  The 
Company  accrues  a  liability  with  respect  to  these  obligations  based  on  its  estimate  of  the  timing  and  amount  to 
replace, remove or retire the associated assets.

In  estimating  the  liability  associated  with  its  asset  retirement  obligations,  the  Company  utilizes  several 
assumptions,  including  a  credit-adjusted  risk-free  interest  rate,  estimated  costs  of  decommissioning  services, 
estimated  timing  of  when  the  work  will  be  performed  and  a  projected  inflation  rate.  Changes  in  estimate  in  the 
table  below  represent  changes  to  the  expected  amount  and  timing  of  payments  to  settle  its  asset  retirement 
obligations. Typically, these changes result from obtaining new information about the timing of its obligations to 
plug and abandon oil and natural gas wells and the costs to do so. After initial recording, the liability is increased 
for  the  passage  of  time,  with  the  increase  being  reflected  as  accretion  expense  in  the  Company’s  consolidated 
statements of operations. If the Company incurs an amount different from the amount accrued for decommissioning 
obligations, the Company recognizes the difference as an adjustment to proved properties.

The carrying amounts are net of discount and deferred financing costs.

As of December 31, 2018 and 2017, the carrying amounts of cash and cash equivalents, accounts receivable, 
restricted  cash  and  accounts  payable  approximate  their  fair  values  because  of  the  short-term  nature  of  these 
instruments. 

11.00%  Second-Priority  Senior  Secured  Notes  –  due  April  2022.  The  $390.9  million  aggregate  principal 
amount of 11.00% Senior Secured Notes is reported on the consolidated balance sheet at its carrying value, net of 
original  issue  discount  and  deferred  financing  costs,  see  Note  6  —  Debt.  The  fair  value  of  the  11.00%  Senior 
Secured Notes is estimated (representing a Level 1 fair value measurement) using quoted secondary market trading 
prices.

7.50% Senior Secured Notes – due May 2022. The $6.1 million aggregate principal amount of 7.50% Stone 
Senior Notes is reported on the consolidated balance sheet as of December 31, 2018 at its carrying value, see Note 
6  —  Debt.  The  fair  value  of  the  7.50%  Stone  Senior  Notes  is  estimated  (representing  a  Level  1  fair  value 
measurement) using quoted secondary market trading prices.

Bank  Credit  Facility  –  due  May  2022.  On  May  10,  2018,  in  connection  with  the  Stone  Combination,  the 
Talos  Energy  LLC  senior  reserve-based  revolving  credit  facility  (“LLC  Bank  Credit  Facility”)  was  repaid  and 
terminated, and the Company executed a new Bank Credit Facility with an initial borrowing base of $600.0 million 
(the  “Bank  Credit  Facility”).  The  LLC  Bank  Credit  Facility  was  repaid  with  borrowings  from  the  Bank  Credit 
Facility  and  cash  acquired  in  the  Stone  Combination.  The  Company’s  Bank  Credit  Facility  is  reported  on  the 
consolidated balance sheet as of December 31, 2018 at its carrying value net of deferred financing costs, see Note 6 
—  Debt.  The  fair  value  of  the  Bank  Credit  Facility  is  estimated  based  on  the  outstanding  borrowings  under  the 
Company’s Bank Credit Facility since it is secured by the Company’s reserves and the interest rates are variable 
and reflective of market rates (representing a Level 2 fair value measurement). 

Oil and natural gas derivatives. The Company attempts to mitigate a portion of its commodity price risk and 
stabilize cash flows associated with sales of oil and natural gas production through the use of oil and natural gas 
swaps and costless collars. Swaps are contracts where the Company either receives or pays depending on whether 
the oil or natural gas floating market price is above or below the contracted fixed price. Costless collars consist of a 
purchased put option and a sold call option with no net premiums paid to or received from counterparties. Collar 
contracts  typically  require  payments  by  the  Company  if  the  NYMEX  average  closing  price  is  above  the  ceiling 
price or payments to the Company if the NYMEX average closing price is below the floor price.

The Company has elected not to designate any of its derivative contracts for hedge accounting. Accordingly, 
commodity  derivatives  are  recorded  on  the  consolidated  balance  sheet  at  fair  value  with  settlements  of  such 
contracts, and changes in the unrealized fair value, recorded as price risk management activities income (expense) 
on the consolidated statements of operations in each period. 

The  following  table  presents  the  impact  that  derivatives,  not  qualifying  as  hedging  instruments,  had  on  its 

consolidated statements of operations (in thousands):

Financial  Statement  Presentation.  Derivatives  are  classified  as  either  current  or  non-current  assets  or 
liabilities based on their anticipated settlement dates. Although the Company has master netting arrangements with 
its  counterparties,  the  Company  present  its  derivative  financial  instruments  on  a  gross  basis  in  its  consolidated 
balance sheets. On derivative contracts recorded as assets in the table below, the Company is exposed to the risk 
the counterparties may not perform. The following table presents the fair value of derivative financial instruments 
at December 31, 2018 and 2017 (in thousands):

Credit  Risk.  The  Company  is  subject  to  the  risk  of  loss  on  its  financial  instruments  as  a  result  of 
nonperformance by counterparties pursuant to the terms of their contractual obligations. The Company entered into 
International Swaps and Derivative Association agreements with counterparties to mitigate this risk. The Company 
also maintains credit policies with regard to its counterparties to minimize overall credit risk. These policies require 
(i)  the  evaluation  of  potential  counterparties’  financial  condition  to  determine  their  credit  worthiness;  (ii)  the 
regular monitoring of counterparties’ credit exposures; (iii) the use of contract language that affords the Company 
netting or set off opportunities to mitigate exposure risk; and (iv) potentially requiring counterparties to post cash 
collateral, parent guarantees or letters of credit to minimize credit risk. The Company’s assets and liabilities from 
commodity  price  risk  management  activities  at  December 31,  2018  represent  derivative  instruments  from  nine 
counterparties;  all  of  which  are  registered  swap  dealers  that  have  an  “investment  grade”  (minimum  Standard  & 
Poor’s  rating  of  BBB-  or  better)  credit  rating,  and  seven  of  which  are  parties  under  the  Company’s  Bank  Credit 
Facility.  The  Company  enters  into  derivatives  directly  with  these  counterparties  and,  subject  to  the  terms  of  the 
Company’s Bank Credit Facility, is not required to post collateral or other securities for credit risk in relation to the 
derivative activities.

In connection with the Stone Combination, the Company consummated the Transactions, pursuant to which 
(i) the  Apollo  Funds  and  Riverstone  Funds  contributed  $102.0 million  in  aggregate  principal  amount  of  9.75% 
Senior Notes to the Company in exchange for Common Stock; (ii) the holders of 11.00% Bridge Loans exchanged 
such  11.00%  Bridge  Loans  for  $172.0  million  aggregate  principal  amount  of  11.00%  Senior  Secured  Notes  and 
(iii) Franklin Noteholders and MacKay Noteholders exchanged their 7.50% Stone Senior Notes for $137.4 million 
aggregate principal amount of 11.00% Senior Secured Notes. An additional $81.5 million of 7.50% Stone Senior 
Notes held by non-affiliates were also exchanged for 11.00% Senior Secured Notes pursuant to an exchange offer 
and consent solicitation in connection with the Stone Combination. 

The  exchanges  to  11.00%  Senior  Secured  Notes  were  accounted  for  as  a  debt  modification.  Under  a  debt 
modification, a new effective interest rate that equates the revised cash flows to the carrying amount of the 11.00% 
Senior Secured Notes is computed and applied prospectively. Costs incurred with third parties directly related to 
the modification are expensed as incurred. The Company incurred approximately $4.3 million of transaction fees 
related  to  the  modification  which  were  expensed  and  reflected  in  general  and  administrative  expense  on  the 
consolidated  statements  of  operations  during  the  year  ended  December 31,  2018.  The  Company  also  paid  $9.3 
million in work fees to holders of the 11.00% Senior Secured Notes, which are reflected as debt discount reducing 
long-term debt on the consolidated balance sheet.

11.00%  Second-Priority  Senior  Secured  Notes  –  due  April  2022.  The  11.00%  Senior  Secured  Notes  were 
issued  pursuant  to  an  indenture  dated  May  10,  2018,  between  the  Talos  Issuers,  the  subsidiary  guarantors  party 
thereto  and  Wilmington  Trust,  National  Association,  as  trustee  and  collateral  agent.  The  11.00%  Senior  Secured 
Notes mature April 3, 2022 and have interest payable semi-annually each April 15 and October 15. Prior to May 
10, 2019, the Company may, at its option, redeem all or a portion of the 11.00% Senior Secured Notes at 100% of 
the principal amount plus accrued and unpaid interest and a make-whole premium. Thereafter, the Company may 
redeem all or a portion of the 11.00% Senior Secured Notes at redemption prices decreasing annually from 105.5% 
to 100.0% plus accrued and unpaid interest.

The  indenture  governing  the  11.00%  Senior  Secured  Notes  applies  certain  limitations  on  the  Company’s 
ability and the ability of its subsidiaries to, among other things, (i) incur additional indebtedness or issue certain 
preferred  shares;  (ii)  pay  dividends  and  make  certain  other  restricted  payments;  (iii)  create  restrictions  on  the 
payment  of  dividends  or  other  distributions  to  the  Company  from  its  restricted  subsidiaries;  (iv)  create  liens  on 
certain assets to secure debt; (v) make certain investments; (vi) engage in sales of assets and subsidiary stock; (vii) 
transfer all or substantially all of its assets or enter into merger or consolidation transactions; and (viii) engage in 
transactions with affiliates. The 11.00% Senior Secured Notes contain customary quarterly and annual reporting, 
financial and administrative covenants. The Company was in compliance with all debt covenants at December 31, 
2018.

7.50% Senior Secured Notes – due May 2022.  The 7.50% Stone Senior Notes represent the remaining $6.1 
million of long-term debt assumed in the Stone Combination that were not exchanged for 11.00% Senior Secured 
Notes  pursuant  to  the  Exchange  Offer  and  Consent  Solicitation,  and  thus  remain  outstanding.  As  a  result  of  the 
exchange  offer  and  consent  solicitation,  substantially  all  of  the  restrictive  covenants  relating  to  the  7.50%  Stone 
Senior  Notes  have  been  removed  and  collateral  securing  the  7.50%  Stone  Senior  Notes  has  been  released.  The 
7.50%  Stone  Senior  Notes  mature  May  31,  2022  and  have  interest  payable  semi-annually  each  May  31  and 
November 30. Prior to May 31, 2020, the Company may, at its option, redeem all or a portion of the 7.50% Stone 
Senior  Notes  at  100%  of  the  principal  amount  plus  accrued  and  unpaid  interest  and  a  make-whole  premium. 
Thereafter,  the  Company  may  redeem  all  or  a  portion  of  the  7.50%  Stone  Senior  Notes  at  redemption  prices 
decreasing annually from 105.625% to 100.0% plus accrued and unpaid interest. 

Bank  Credit  Facility  –  due  May  2022.  Talos  Production  LLC,  a  subsidiary  of  the  Company,  executed  the 
Bank Credit Facility in conjunction with the Stone Combination with a syndicate of financial institutions, with an 
initial  borrowing  base  of  $600.0  million.  The  Bank  Credit  Facility  is  currently  scheduled  to  mature  on  May  10, 
2022.  

The  Bank  Credit  Facility  bears  interest  based  on  the  borrowing  base  usage,  at  the  applicable  London 
InterBank Offered Rate, plus applicable margins ranging from 2.75% to 3.75% or an alternate base rate, based on 
the federal funds effective rate plus applicable margins ranging from 1.75% to 2.75%. In addition, the Company is 
obligated to pay a commitment fee of 0.50% on the unfunded portion of the commitments under the Bank Credit 
Facility.  The  Bank  Credit  Facility  has  certain  debt  covenants,  the  most  restrictive  of  which  is  that  the  Company 
must maintain a total debt to EBITDAX Ratio (as defined in the Bank Credit Facility) of no greater than 3.00 to 
1.00  each  quarter.  The  Company  must  also  maintain  a  current  ratio  no  less  than  1.00  to  1.00  each  quarter. 
According  to  the  Bank  Credit  Facility,  undrawn  commitments  are  included  in  current  assets  in  the  current  ratio 
calculation.  The  Bank  Credit  Facility  is  secured  by  substantially  all  of  the  oil  and  natural  gas  assets  of  the 
Company.  The  Bank  Credit  Facility  is  fully  and  unconditionally  guaranteed  by  the  Company  and  certain  of  its 
wholly-owned subsidiaries.

The Bank Credit Facility provides for determination of the borrowing base based on the Company’s proved 
producing reserves and a portion of its proved undeveloped reserves. The borrowing base is redetermined by the 
lenders at least semi-annually during the second quarter and fourth quarter. On November 16, 2018 the borrowing 
base was increased from $600.0 million to $850.0 million. However, the Company elected to maintain the $600.0 
million commitment based upon its current liquidity needs. The next redetermination is scheduled for April 2019.

As of December 31, 2018, commitments under the Company’s borrowing base was set at $600.0 million, of 
which no more than $200.0 million can be used as letters of credit. The amount the Company is able to borrow with 
respect  to  the  borrowing  base  is  subject  to  compliance  with  the  financial  covenants  and  other  provisions  of  the 
Bank  Credit  Facility.  The  Company  was  in  compliance  with  all  debt  covenants  at  December 31,  2018.  As  of 
December 31, 2018, the Bank Credit Facility had approximately $320.3 million of undrawn commitments (taking 
into account $14.7 million letters of credit and $265.0 million drawn from the Bank Credit Facility).

Building  Loan  –  due  November  2030.  In  connection  with  the  Stone  Combination,  the  Company  assumed 
Stone’s 4.20% term loan maturing on November 20, 2030 (the “Building Loan”). The Building Loan bears interest 
at a rate of 4.20% per annum and is to be repaid in 180 equal monthly installments of approximately $0.1 million. 
As  of  December 31,  2018,  the  outstanding  balance  under  the  Building  Loan  totaled $10.6  million.  The  Building 
Loan  is  collateralized  by  the  Company’s  two  office  buildings  in  Lafayette,  Louisiana.  Under  the  financial 
covenants of the Building Loan, the Company must maintain a ratio of EBITDA to Net Interest Expense of not less 
than 2.00 to  1.00.  In  addition,  the  Building  Loan  contains  certain  customary  restrictions  or  requirements  with 
respect  to  change  of  control  and  reporting  responsibilities.  The  Company  was  in  compliance  with  all  covenants 
under the Building Loan as of December 31, 2018.

9.75% Senior Notes – due February 2018. The 2018 Senior Notes were issued pursuant to an indenture dated 
February 6, 2013 among the Talos Issuers, the subsidiaries, as issuers, the subsidiary guarantors party thereto and 
the trustee. On February 15, 2018, the Talos Issuers redeemed the remaining $25.0 million principal amount of the 
9.75% Senior Notes at par. 

Subsequent Event. On January 22, 2019, the Company borrowed $35.0 million from the Bank Credit Facility 

to fund 2019 acquisition activities, see Note 15 — Subsequent Events.

Note 7 — Employee Benefits Plans and Share-Based Compensation  

Stone Change of Control and Severance Plans

The  Company  maintains  the  Stone  Energy  Corporation  Executive  Severance  Plan  and  Stone  Energy 
Corporation  Employee  Severance  Plan,  each  a  legacy  plan  of  Talos  Petroleum  LLC  (f/k/a  Stone  Energy 
Corporation). The plans provide for the payment of severance and change in control benefits to certain individuals 
who, prior to the Stone Combination, were executive officers or employees of Talos Petroleum LLC, in each case 
upon  an  involuntary  termination  within  twelve  months  of  Closing.  For  the  year  ended  December 31,  2018  the 
Company  incurred  $7.8  million  of  severance  expense,  reflected  in  general  and  administrative  expense  on  the 
consolidated  statement  of  operations.  Approximately  $0.3  million  of  such  expense  remained  unpaid  at 
December 31, 2018. 

Talos Energy Inc. Long Term Incentive Plan

In connection with the Closing, the Company adopted the Talos Energy Inc. Long Term Incentive Plan (the 
“LTIP”),  pursuant  to  which  the  Company  may  issue,  subject  to  Board  approval,  grants  of  options,  stock 
appreciation  rights,  restricted  stock,  restricted  stock  units,  stock  awards,  dividend  equivalents,  other  stock-based 
awards,  cash  awards,  substitute  awards  or  any  combination  of  the  foregoing  to  employees,  directors  and 
consultants.  The  LTIP  authorizes  the  Company  to  grant  awards  of  up  to  5,415,576  shares  of  the  Company’s 
Common Stock.  

Restricted  Stock  Units  –  Employees.  During  the  year  ended  December 31,  2018,  the  Company  granted 
116,448  RSUs  under  the  LTIP  to  employees.  These  RSUs  had  a  grant  date  fair  value  of  $3.9  million  and  vest 
ratably  over  an  approximate  three  year  period,  which  began  on  May 14,  2018,  subject  to  such  employee’s 
continued service through each vesting date. Upon vesting, each RSU represents a contingent right to receive one 
share  of  Common  Stock.  The  total  unrecognized  share-based  compensation  expense  related  to  these  RSUs  at 
December 31, 2018 was approximately $3.3 million, which is expected to be recognized over a weighted average 
period of 2.4 years. 

Restricted  Stock  Units  –  Non-employee  Directors.  On  May  21,  2018,  the  Company  granted  22,963  RSUs 
under the LTIP to non-employee directors. These RSUs had a grant date fair value of $0.8 million and vest on May 
19, 2019, subject to such non-employee director’s continued service through the vesting date. Upon vesting, these 
RSUs represent a contingent right to receive one share of Common Stock for each RSU for 60% or 13,778 of these 
RSUs, and cash for the remaining 40% or 9,185 of these RSUs. The total unrecognized share-based compensation 
expense  related  to  these  RSUs  at  December 31,  2018  was  approximately  $0.2  million,  which  is  expected  to  be 
recognized over a weighted average period of 0.4 years. Of the unrecognized share-based compensation expense, 
$0.1 million relates to liability awards and will be subsequently remeasured at each reporting period.

Performance  Share  Units  –  Employees.  During  the  year  ended  December 31,  2018,  the  Company  granted 
232,891  PSUs  to  employees  with  each  PSU  representing  the  contingent  right  to  receive  one  share  of  Common 
Stock.  However,  the  number  of  Common  Stock  shares  issuable  upon  vesting  ranges  from  zero  to  200%  of  the 
number of PSUs granted based on the total shareholder return (“TSR”) of the Common Stock relative to the TSR 
achieved  by  a  specific  industry  peer  group  over  an  approximate  three-year  performance  period,  the  last  day  of 
which is also the vesting date. The total unrecognized share-based compensation expense related to these PSUs at 
December 31, 2018 was approximately $9.2 million, which is expected to be recognized over a weighted average 
period of 2.4 years.

Prior to the Stone Combination, the Limited Liability Company Agreement of Talos Energy LLC established 
Series  A,  Series  B  and  Series  C  Units.  Series  B  Units  were  generally  intended  to  be  used  as  incentives  for 
Company employees. Series B Units do not participate in distributions prior to vesting or until Series A Units have 
received cumulative distributions equal to (i) the original cash contributed to the Company for such Series A Units 
and (ii) an 8% return, compounded annually (the “Aggregate Series A Payout”), and Series C Units have received 
$25.0 million in distributions. In connection with the Transactions, the Series A, Series B and Series C Units were 
exchanged  for  an  equivalent  number  of  units  in  each  of  an  entity  affiliated  with  the  Apollo  Funds  and  an  entity 
affiliated with the Riverstone Funds, each of which hold Common Stock of the Company. The modification did not 
result in incremental value to the Series B Units. 

For accounting and financial reporting purposes, the Series B Units are deemed to be equity awards, and the 
compensation  expense  related  to  these  awards  is  recorded  on  a  straight-line  basis  over  the  vesting  period  in  the 
Company’s consolidated financial statements and is reflected as a corresponding credit to accumulated deficit on 
the consolidated balance sheet. 

The  Company’s  unrecognized  compensation  expense  at  December 31,  2018  is  approximately  $2.7 million. 
Of  this  amount,  approximately  $0.5 million  of  the  unrecognized  compensation  expense  will  continue  to  be 
recognized  on  a  straight-line  basis  over  the  remainder  of  the  four  year  requisite  service  period.  The  remaining 
$2.2 million will be recognized upon an Aggregate Series A Payout. The weighted-average period over which the 
unrecognized compensation expense for the Series B Units will be recognized is 1.7 years. 

New Talos Energy LLC Series B Units

In  connection  with  the  transactions  contemplated  in  the  Exchange  Agreement  on  May  10,  2018,  an  entity 
affiliated with the Apollo Funds and an entity affiliated with the Riverstone Funds, each of which hold Common 
Stock in the Company as a result of the Sponsor Debt Exchange, established new Series A Units (“New Series A 
Units”) and new Series B Units (“New Series B Units”). The New Series B Units are generally intended to be used 
as incentives for Company employees.  

The New Series B Units do not participate in distributions prior to vesting or until the New Series A Units 
have received cumulative distributions of $102.0 million. After issuance, 80% of the New Series B Units vest on a 
monthly basis over a four year period based on the initial vesting schedule of the original Series B Units, subject to 
continued  employment.  All  unvested  New  Series  B  Units  fully  vest  upon  the  cumulative  distribution  of  $102.0 
million.

For accounting and financial reporting purposes, the New Series B Units are deemed to be equity awards, and 
the compensation expense related to these awards is recorded on a straight-line basis over the vesting period in the 
Company’s consolidated financial statements and is reflected as a corresponding credit to accumulated deficit on 
the consolidated balance sheet.  

The New Series B Units issued were valued using the option pricing method for valuing securities. In this 
method,  the  rights  and  claims  of  each  security  are  modeled  as  a  portfolio  of  Black-Scholes-Merton  call  options 
written on the total equity of the entities affiliated with the Apollo Funds and Riverstone Funds. The total value of 
the equity is calculated in an iterative process that results in the New Series A Units being valued at par. The risk-
free rate of interest is based on the U.S. Treasury yield curve on the grant date. The expected time to a liquidity 
event  is  based  on  a  weighted  average  calculation  of  management’s  estimate  considering  market  conditions  and 
expectations.  The  expected  volatility  of  equity  is  based  on  the  volatility  of  the  assets  of  similar  publicly  traded 
companies using a Black-Scholes-Merton model. The discount for lack of marketability is based on the restrictions 
on the New Series B Units and the volatility of the New Series B Units using a Black-Scholes-Merton model.

The  Company’s  unrecognized  compensation  expense  at  December 31,  2018  is  approximately  $1.2 million. 
Of  this  amount,  approximately  $0.2 million  of  the  unrecognized  compensation  expense  will  continue  to  be 
recognized  on  a  straight-line  basis  over  the  remainder  of  the  four  year  requisite  service  period.  The  remaining 
$1.0 million will be recognized upon the New Series A Units receiving the cumulative distribution. The weighted-
average period over which the unrecognized compensation expense will be recognized is 0.8 months.

Share-based Compensation Expense, net

Share-based compensation expense associated with RSUs, PSUs and Series B Units are reflected as general 
administrative  expense,  net  amounts  capitalized  to  oil  and  gas  properties  in  the  consolidated  statement  of 
operations.  Because  of  the  non-cash  nature  of  share-based  compensation,  the  expensed  portion  of  share-based 
compensation is added back to net income in arriving at net cash used in or provided by operating activities in the 
consolidated statement of cash flows. 

For  the  year  ended  December 31,  2018,  share-based  compensation  expense  did  not  have  any  associated 
income  tax  benefit.  The  Company  recognized  the  following  share-based  compensation  expense,  net  for  the

Prior to the Stone Combination, Talos Energy LLC was a partnership for U.S. federal income tax purposes 
and  was  not  subject  to  U.S.  federal  income  tax  or  state  income  tax  (in  most  states)  at  the  entity  level.  As  such, 
Talos Energy LLC did not recognize U.S. federal income tax expense or state income tax expense in most states. 
Talos  Energy  LLC’s  operations  in  the  shallow  waters  off  the  coast  of  Mexico  were  conducted  under  a  different 
legal form and are subject to foreign income taxes. 

In  connection  with  the  Stone  Combination,  Talos  Energy  LLC  was  contributed  to  the  Company,  which  is 
subject to federal and state income taxes. The Company is also subject to foreign income taxes. Due to the change 
in tax status, deferred taxes are recorded for differences in book and tax basis. The Company’s differences in its 
book and tax basis in its assets and liabilities is primarily related to different cost recovery periods utilized for book 
and tax purposes for the Company’s oil and natural gas properties, asset retirement obligations and net operating 
loss carryforwards. A valuation allowance is established to reduce deferred tax assets when it is more likely than 
not that some portion or all of the deferred tax asset will not be realized. The Company believes it is more likely

than not that the net federal deferred tax asset will not be realized and therefore recorded a valuation allowance. 
Due to the valuation allowance, the tax expense resulting from the initial book and tax basis difference from the 
change  in  tax  status  was  zero.  The  Company  accounted  for  the  book  and  tax  basis  difference  from  the  Stone 
Combination  in  acquisition  method  accounting  and  recorded  an  estimated  state  deferred  tax  liability  of  $2.7 
million.  

As  part  of  the  Stone  Combination,  entities  related  to  the  Apollo  Funds  and  Riverstone  Funds  contributed 
entities to the Company that were under common control. At December 31, 2018, the Company also estimated a 
net  deferred  tax  asset  related  to  tax  loss  carryforwards  and  differences  in  book  and  tax  basis  of  assets.  The  net 
deferred  tax  asset  and  valuation  allowance  from  the  contribution  is  accounted  for  in  stockholder’s  equity.  The 
Company  believes  it  is  more  likely  than  not  that  the  net  deferred  tax  asset  will  not  be  realized  and  therefore 
recorded a valuation allowance.

As a result of the Stone Combination, the Company acquired a current income tax receivable of $10.7 million 

primarily related to the carryback of specified liability losses.  

Tax Cuts and Jobs Act. On December 22, 2017, the President signed into law Public Law No. 115-97 (“Tax 
Act”), an Act to provide for reconciliation pursuant to titles II and V of the concurrent resolution on the budget for 
fiscal year 2018. The Tax Act made broad and complex changes to the U.S. tax code. The SEC issued SAB 118, 
which has since been codified into ASC 740, providing guidance on the accounting for the tax effects of the Tax 
Act. ASC 740 provides a measurement period that should not extend beyond one year from the Tax Act enactment 
date to complete the accounting under ASC 740. In accordance with this pronouncement, the Company completed 
its  assessment  on  certain  effects  of  the  Tax  Act  in  the  financial  statements  for  the  period  ending  December  31, 
2018. In assessing the need for a valuation allowance on its deferred tax assets, the Company considered whether it 
was more likely than not that some portion or all of them will not be realized. Due to a full valuation allowance 
against the Company’s deferred tax assets, the adjustments did not have any net impact on tax expense for 2018.

The Company’s effective tax rate for the year ending December 31, 2018, differed from the federal statutory 
rate of 21.0% primarily due to recording a valuation allowance for its deferred tax assets. The effective tax rate for 
years 2017 and 2016 differed from the federal statutory rate of 35.0% because the Company was not subject to U.S. 
federal or state taxation as a partnership and the Company’s Mexico operations did not incur a material income tax 
expense.

Income Tax Receivables and Payables

As of December 31, 2018, the Company recorded current income tax receivables of $10.7 million. As a result 
of  the  Stone  Combination,  the  Company  acquired  the  current  income  tax  receivable  primarily  related  to  the 
carryback  of  specified  liability  losses.  The  Company  has  also  recorded  an  income  tax  payable  of  $1.3  million 
primarily related to estimated taxes for the 2018 Mexico tax returns.

Revenue Code (“IRC”). IRC Section 382 provides an annual limitation with respect to the ability of a corporation 
to utilize its tax attributes, against future U.S. taxable income in the event of a change in ownership. If not utilized, 
such carryforwards would begin to expire in 2034.

Valuation Allowance 

During  2018,  the  Company  recorded  a  valuation  allowance  of  $94.1  million  related  to  federal,  state  and 
foreign  deferred  tax  assets.  Deferred  tax  assets  are  recorded  related  to  net  operating  losses  and  temporary 
differences  between  the  book  and  tax  basis  of  assets  and  liabilities  expected  to  produce  tax  deductions  in  future 
periods. The realization of these assets depends on recognition of sufficient future taxable income in specific tax 
jurisdictions in which those temporary differences or net operating losses are deductible. In assessing the need for a 
valuation  allowance  on  deferred  tax  assets,  the  Company  considers  whether  it  is  more  likely  than  not  that  some 
portion  or  all  of  them  will  not  be  realized. As  of  December 31,  2018,  the  Company  had  a  valuation  allowance 
related to federal, state and foreign deferred tax assets. The Company did not record a valuation allowance during 
2017 for federal and state deferred tax assets as the Company was not subject to taxation as a partnership during 
this period.   

Uncertain Tax Positions 

The table below sets forth the beginning and ending balance of the total amount of unrecognized tax benefits.  
There  are  no  unrecognized  benefits  that  would  impact  the  effective  tax  rate  if  recognized.  While  amounts  could 
change  in  the  next  12  months,  the  Company  does  not  anticipate  having  a  material  impact  on  its  financial 
statements.  

Balances in the uncertain tax positions are as follows (in thousands): 

Total unrecognized tax benefits, beginning balance

The  Company  recognizes  interest  and  penalties  related  to  uncertain  tax  positions  as  interest  expense  and 

general and administrative expenses, respectively.  

Years open to examination 

The 2015 through 2017 tax years remain open to examination by the tax jurisdictions in which the Company 
is subject to tax. The statute of limitations with respect to the U.S. federal income tax returns of the Company for 
years ending on or before December 31, 2014 are closed.  

Note 9 — Earnings Per Share

Basic earnings per common share is computed by dividing net income (loss) by the weighted average number 
of shares of common stock outstanding during the period.  Except when the effect would be antidilutive, diluted 
earnings per common share includes the impact of RSUs, PSUs and outstanding warrants. 

As  of  December 31,  2018,  the  Company  had  approximately  3.5  million  outstanding  warrants.   These 
warrants  have  an  exercise  price  of  $42.04  per  share  and  a  term  of  four  years  ending  February  28,  2021.  As  of 
December 31,  2018,  the  Company  had  138,704  and  231,542  outstanding  RSUs  and  PSUs,  respectively,  which 
settle in shares of Common Stock.  

For the year ended December 31, 2018, dilutive weighted average shares for RSUs and PSUs totaled 2,819 
shares  resulting  in  an  increase  to  the  basic  weighted  average  common  shares  of  46,058,216  to  arrive  at  diluted 
weighted  average  common  shares  outstanding  of  46,061,035.  For  the  year  ended  December 31,  2018,  419,639 
weighted  average  antidilutive  RSUs  and  PSUs  were  excluded  from  the  computation  of  diluted  earnings  per 
common  share.  Additionally,  for  the  year  ended  December 31,  2018,  all  outstanding  warrants  were  considered

For  the  periods  prior  to  May  10,  2018,  the  Company  retrospectively  adjusted  the  weighted  average  shares 
used  in  determining  earnings  per  share  to  reflect  the  number  of  shares  Talos  Energy  LLC  received  in  the  Stone 
Combination.  There  is  no  impact  in  fiscal  year  2017  and  2016  on  diluted  earnings  per  common  share  from  the 
RSUs, PSUs and outstanding warrants as these instruments did not exist throughout such periods.

Registration  Rights  Agreement  with  each  of  the  Apollo  Funds,  Riverstone  Funds,  Franklin  and  MacKay  Shields 
relating to the registered resale of its Common Stock owned by such parties as of Closing. The Company will bear 
all  of  the  expenses  incurred  in  connection  with  the  offer  and  sale,  while  the  Apollo  Funds,  Riverstone  Funds, 
Franklin and MacKay Shields are responsible for paying underwriting fees, discounts and commissions or similar 
charges.  Fees incurred by the Company in conjunction with the Equity Registration Rights Agreement were $1.8 
million for the year ended December 31, 2018.

Legal Fees. The Company has engaged the law firm Vinson & Elkins L.L.P. to provide legal services. An 
immediate family member of William S. Moss III, the Company’s Executive Vice President and General Counsel 
and one of its executive officers, is a partner at Vinson & Elkins L.L.P. For the year ended December 31, 2018, 
2017  and  2016,  the  Company  incurred  fees  of  approximately  $4.4  million,  $4.0  million  and  $0.7  million, 
respectively,  of  which  $1.1  million,  $4.0  million  and  $0.1  million  were  payable  at  each  respective  balance  sheet 
date for legal services performed by Vinson & Elkins L.L.P.

not  receive  any  cash  contributions  or  make  any  distributions  to  Apollo  Funds  and  Riverstone  Funds.  During  the 
year  ended  December  31,  2016,  the  Company  received  a  $93.8  million  ($91.9  million  net  of  $1.9  million  of 
transaction  fees)  capital  contribution  from  Apollo  Funds  and  Riverstone  Funds  primarily  to  fund  the  Sojitz

Transaction  Fee  Agreement.  As  part  of  the  agreements  with  Apollo  Funds  and  Riverstone  Funds,  the 
Company paid a transaction fee equal to 2% of capital contributions made by Apollo Funds and Riverstone Funds. 
For the years ended December 31, 2018 and 2017, there were no capital contributions and thus the Company did 
not  incur  or  pay  transaction  fees  related  to  capital  contributions.  For  the  year  ended  December  31,  2016  the 
Company incurred fees totaling $1.9 million related to the capital contributions received from Apollo Funds and

agreement,  the  Company  paid  a  fee  equal  to  the  higher  of  (i)  a  certain  percentage  of  earnings  before  interest, 
income taxes, depletion, depreciation and amortization and (ii) a fixed fee payable quarterly, provided, however, 
such  fees  did  not  exceed  in  each  case  $0.5 million,  in  aggregate,  for  any  calendar  year.  For  the  year  ended 
December 31,  2018,  2017  and  2016,  the  Company  incurred  approximately  $0.5  million,  $0.5  million  and  $0.5 
million,  respectively,  for  these  services.  These  fees  are  recognized  in  general  and  administrative  expense  on  the 
consolidated statements of operations. In connection with the Stone Combination on May 10, 2018, the Service Fee 
Agreement was terminated.

Note 11 — Commitments and Contingencies

Capital Lease

On August 2, 2016, the Company executed a seven-year lease agreement (the “Agreement”), effective June 
1, 2016, with Helix for use of the HP-I to process hydrocarbons produced from the Phoenix Field. Under the terms 
of  the  Agreement,  the  Company  paid  Helix  a  $49.0  annual  fixed  demand  charge  plus  a  potential  $0.5  million 
quarterly incentive payment if certain uptime rates were achieved. Thereafter the Company will pay a $45.0 annual 
fixed demand charge plus a potential $0.8 million quarterly incentive payment if certain uptime rates are achieved. 

The Agreement with Helix is accounted for as a capital lease. The Company initially recorded both a capital 
lease  asset  and  obligation  of  $124.3  million  on  its  consolidated  balance  sheet.  As  of  December 31,  2018,  the 
balance of the capital lease obligation on the consolidated balance sheet is $93.6 million, of which $14.1 million is 
included in other current liabilities and $79.5 million is included in other long-term liabilities. As a result of the 
Agreement being accounted for as a capital lease, the lease payments are reflected as (i) a reduction of the capital 
lease obligation, (ii) interest expense and (iii) direct lease operating expense. 

As of December 31, 2018, minimum lease commitments for the capital lease in future years are as follows (in 

thousands):

2019
2020
2021

On January 6, 2016, Energy Resource Technology GOM, LLC (“ERT”) plead guilty to two violations of the 
Clean Water for self-reported activities surrounding overboard discharge sampling and unpermitted discharges and 
two  violations  of  Outer  Continental  Shelf  Lands  Act.  On  April  6,  2016,  the  United  States  District  Court  for  the 
Eastern District of Louisiana accepted ERT’s plea and sentenced ERT, consistent with the plea agreement, to pay a 
penalty of $4.2 million which ERT has paid. The Court placed ERT on probation for three years. The conditions of 
probation include compliance with an agreed Safety and Environmental Compliance Program. As a result of ERT’s 
conviction for violations of the Clean Water Act, ERT was debarred and cannot enter into contracts with or receive 
benefits  from  the  federal  government,  until  the  EPA  reinstates  ERT  by  certifying  that  ERT  has  corrected  the 
conditions  giving  rise  to  the  Clean  Water  convictions.  EPA  also  imposed  discretionary  suspension  and  proposed 
debarment on Talos Production LLC, Talos Energy Offshore LLC and Talos Energy LLC as affiliates of ERT. On 
November  23,  2016,  EPA  terminated  and  administratively  closed  the  suspension  as  to  each  of  the  three  entities 
previously suspended. On August 29, 2017, EPA certified that the conditions giving rise to ERT’s conviction were 
corrected, and its debarment was lifted.  

The  Company  is  named  as  a  party  in  certain  lawsuits  and  regulatory  proceedings  arising  in  the  ordinary 
course of business. The Company does not expect that these matters, individually or in the aggregate, will have a 
material adverse effect on its financial condition.

Performance Obligations 

Regulations  with  respect  to  offshore  operations  govern,  among  other  things,  engineering  and  construction 
specifications for production facilities, safety procedures, plugging and abandonment of wells, removal of facilities 
and to guarantee the execution of the minimum work program under the Mexico production sharing contracts. As 
of  December 31,  2018  and  2017,  the  Company  had  secured  performance  bonds  totaling  approximately  $644.1 
million and $287.8 million, respectively. As of December 31, 2018 and 2017, the Company had $14.7 million and 
$4.9 million, respectively, in letters of credit issued under its Bank Credit Facility.

Estimated Quantities of Proved Oil, Natural Gas and NGL Reserves

The  Company  employs  full-time  experienced  reserve  engineers  and  geologists  who  are  responsible  for 
determining  proved  reserves  in  compliance  with  SEC  guidelines.  There  are  numerous  uncertainties  inherent  in 
estimating  quantities  of  proved  reserves  and  projecting  future  rates  of  production  and  timing  of  development 
expenditures.  The  reserve  data  in  the  following  tables  only  represent  estimates  and  should  not  be  construed  as 
being exact. Engineering reserve estimates were prepared based upon interpretation of production performance data 
and  sub-surface  information  obtained  from  the  drilling  of  existing  wells.  The  Company’s  Director  of  Reserves, 
internal reservoir engineers and geologists analyzed and prepared reserve estimates on all oil and natural gas fields. 
All of the Company’s proved oil, natural gas and NGL reserves are located in the United States primarily offshore 
Gulf of Mexico.

At December 31, 2018, 2017 and 2016, 100% of proved oil, natural gas and NGL reserves attributable to all 
of  the  Company’s  oil  and  natural  gas  properties  were  estimated  and  complied  for  reporting  purposes  by  the 
Company’s  reservoir  engineers  and  audited  by  Netherland,  Sewell  &  Associates,  Inc.  (“NSAI”),  independent 
petroleum engineers and geologists.

During 2018, the Company added 51.1 MMBoe of estimated proved reserves, which included 62.8 MMBoe 
added  through  purchases  of  59.3  MMBoe  from  the  Stone  Combination  and  3.5  MMBoe  from  the  Whistler 
Acquisition. The Company also added 5.6 MMBoe of estimated proved reserves from extensions and discoveries 
primarily from an evaluation of Green Canyon Block 18. The increase was partially offset by a decrease of 16.7 
MMBoe of production.  

During  2017,  the  Company  added  12.5  MMBoe  of  estimated  proved  reserves  from  extensions  and 
discoveries  primarily  from  drilling  the  Tornado  II  exploration  prospect  in  the  Phoenix  Field.  The  increase  was 
offset by a decrease of 10.5 MMBoe of production and 5.1 MMBoe of negative performance revisions. 

During  2016,  the  Company  added  13.9  MMBoe  of  estimated  proved  reserves  through  the  purchase  of 
reserves  from  the  Sojitz  Acquisition.  The  Company  also  added  26.6  MMBoe  of  estimated  proved  reserves  from 
extensions and discoveries from successful drilling of the Tornado exploration well in the Phoenix Field.

For  December  31,  2017  and  2016,  the  standardized  measure  of  discounted  future  net  cash  flows  did  not  include  the  impact  of  future 
federal income taxes because Talos Energy LLC was not subject to federal income taxes prior to the Stone Combination.

Future  cash  inflows  are  computed  by  applying  SEC  Pricing  to  year-end  quantities  of  proved  reserves.  The 
discounted future cash flow estimates do not include the effects of derivative instruments. See the following table 
for base prices used in determining the standardized measure:

Oil price per Bbl
Natural gas prices per Mcf
NGL price per Bbl

Future net cash flows are discounted at the prescribed rate of 10%. Actual future net cash flows may vary 
considerably from these estimates. Although the Company’s estimates of total proved reserves, development costs 
and production rates were based on the best information available, the development and production of oil and gas 
reserves may not occur in the periods assumed. Actual prices realized, costs incurred and production quantities may 
vary  significantly  from  those  used.  Therefore,  such  estimated  future  net  cash  flow  computations  should  not  be 
considered to represent the Company’s estimate of the expected revenues or the current value of existing proved 
reserves.
