Letter to TEP 
Unitholders

 CHAPTER 4/YEAR 4—A TRADITIONAL MIDSTREAM MLP

  Once  again,  we  turn  the  page  on  another  year  at  Tallgrass.  And 
what a year! 2016 was a year of extremes, the kind of year in the energy 
space—and the MLP space in particular—that we seem to have every 
five  to  seven  years.  We  saw  extremes  in  energy  commodity  pricing, 
particularly to the downside, that eventually rippled through the entire 
energy space—upstream, midstream and downstream.

  Even  though  2016  was  a  rough  year  for  much  of  the  industry, 
Tallgrass never missed a beat and consistently executed our business 
strategy. We continued to increase distributions and deliver the kind of 
value our unitholders have come to expect from us. Before I dive into 
our 2016 performance, I’d like to remind everyone who we are.

  Tallgrass  Energy  Partners,  LP  (TEP)  is  a  traditional  midstream 
operator providing long-term sustainable distribution growth to inves-
tors fueled by strong customer relationships, a significant geographic 
footprint, solid growth potential and a flexible capital structure.

  Again in 2016, I believe we lived up to that reputation. 

It occurs to me as I write this fourth annual letter to my fellow uni-
tholders  that  my  message  may  seem  repetitive.  There’s  a  reason  for 
that: many of our messages at Tallgrass are worth repeating. We have 
a track record for doing what we say we’re going to do. I’ll leave it to 
you to decide if you believe our actions of the past and our facts of the 
present  will  translate  into  our  vision  and  performance  of  the  future 
for Tallgrass. 

MORE ON 2016—PERFORMANCE AND PRESENT VALUE

In February 2016, TEP units hit a 52-week low closing price of 
$25.87—largely  due  to  us  being  painted  with  the  same  brush  as  our 
upstream counterparts. In January 2017, we pushed back up to about 
the $50.00 per unit mark. On Feb. 12, 2016, TEP paid an annualized dis-
tribution of $2.56, which at the time meant that TEP yielded close to 10 
percent.  Even  though  our  unit  price  has  recovered  significantly,  I 
believe TEP remains undervalued. 

  On Feb. 14, 2017, TEP paid an annualized distribution of $3.26 per 
unit ($0.815 quarterly). At a current TEP price of ~$49.00, that equates 
to a yield of nearly 7 percent. Let me lay out my case for why I believe 
TEP is still undervalued.
1. From  February  2016  to  February  2017,  we  raised  our  distribution  by 

27.3 percent—a top 5 annualized growth rate in the MLP space.

2. We  have  told  the  market  we  believe  we  will  have  20  percent  annual-

ized distribution growth in 2017.

3. At  ~7  percent,  TEP’s  current  yield  is  above  both  the  average  and 
median  yield  of  all  MLPs.  Our  view  is  that  on  a  comparative  basis, 
TEP is significantly better than average (the mean) and deserving of a 
much lower yield than the middle value (the median).

4. For 2016 we covered our distribution by greater than 1.25x, generating 
almost  $90  million  in  excess  of  cash  distributed  to  our  unitholders. 
Since  going  public  in  May  2013,  we  have  generated  more  than  $130 
million  of  excess  distribution  coverage  that  we  have  used  to  repay 
debt and reinvest in our business. In 2017 we believe we will cover our 
distributions  by  ~1.40x,  generating  almost  $175  million  in  excess  of 
anticipated distributions, while still growing our distributions at a 20 
percent annualized rate.

5. TEP has an investment grade balance sheet by almost any measure 
and maintains a best-in-class Debt to EBITDA ratio of approximately 
three times.

6. In 2016, as in prior years, we have done what we said we were going 

to do. We intend to keep on doing the same.

2016—ANOTHER  YEAR  OF  EXECUTION—A  YEAR  OF  ~$2.0+ 
BILLION IN ACQUISITIONS AND EXPANSIONS

Pony Express—On Jan. 1, 2016, we bought our final interest 
in the Pony Express crude oil pipeline for $743.6 million, bringing our 
total ownership to 98 percent. At the time, the Seller—TDEV—took back 
6.518 million TEP common units valued at $41.21 a share. In addition, 
TEP  retained  the  right  to  repurchase  (or  “call”)  the  shares  back  at  a 
price of $42.50. We are pleased to report that from that time, TEP was 
able to raise equity at an average price of $47.25 and buy back all 6.518 
million units—netting TEP a retained difference of approximately $31 
million,  thus  reducing  the  transaction  price  by  that  much  as  well  as 
reducing  the  multiple  paid  down  to  an  8.7x  multiple  of  cash  flow.  To 
our  knowledge,  this  is  the  first  time  a  call  strategy  has  been  used 
when issuing equity to a related party and further shows on a histori-
cal  basis  TEP’s  creativity  and  TDEV’s  continuing  commitment  to  the 
ongoing success of TEP.

Rockies Express Pipeline (REX)—In May 2016, we purchased a 
25  percent  equity  interest  in  REX  from  a  subsidiary  of  Sempra  U.S. 
Gas  and  Power  for  $436  million.  The  overall  enterprise  value  of  the 
transaction  exceeded  $1.0  billion.  This  was  TEP’s  first  acquisition  of 
an interest in REX. Our private affiliate, TDEV, still owns 50 percent of 
REX  and  we  expect  sometime  over  the  next  two  years  to  acquire 
TDEV’s 50 percent interest in REX, continuing our growth at TEP. 

At REX, we constructed our Zone 3 Capacity Enhancement proj-
ect.  This  project  added  an  additional  0.8  Bcf/day  of  east-to-west 
capacity in Zone 3 by adding additional horsepower at three new com-
pressor  stations  and  enhancing  two  existing  stations.  This  project 
was placed in full service in early January 2017. We and our partners 
at REX spent approximately $525 million on this project, which is fully 
contracted for 15 years.

We  also  restructured  REX’s  largest  legacy  contract  (0.5  Bcf/d) 
with Encana. The contract was extended to 2024, giving Encana short-
term  rate  relief  in  exchange  for  a  longer-term  contract  with  REX.  It 
was NPV positive at a nice discount rate and was a win/win for both 
REX and its customer.

REX  reached  an  agreement  to  settle  its  $303  million  breach  of 
contract  claim  against  Ultra  Resources,  a  legacy  customer.  REX  will 
receive $150 million in cash during 2017 and a new seven-year contract 
for 0.2 Bcf/d commencing in 2019 for ~$27 million per year. This settle-
ment essentially keeps us whole on our original contract, takes capac-
ity  out  of  the  marketplace  and  allows  us  to  have  a  healthy,  solvent 
customer for the long term at REX.

With two contracts that extend beyond 2019, we now have nearly 
40 percent (0.7 Bcf/d) of the west-end volumes contracted at average 
rates  of  $0.67  with  a  weighted  average  life  of  more  than  five  years 
(post-2019). Combined with the fully contracted zone 3 volumes of 2.6 
Bcf/d,  we  have  now  re-contracted  greater  than  85  percent  of  REX’s 
original cashflow on a long-term basis. With more than two and one 
half years remaining before the rest of the west-end contracts expire, 
we are confident in our ability to secure additional transportation vol-
umes  on  REX,  whether  they  come  from  our  current  customers  or 
potential new customers.

 
 
 
 
 
 
 
 
 
TIGT—At  TIGT,  we  successfully  settled  a  rate  case  with  agreement 
from our customers and approval from the FERC on all issues includ-
ing modernizing our tariff, establishing new reservation rates, imple-
menting fuel and power cost trackers, and simplifying our zoned rate 
structure from five zones to two, all resulting in a $13 million increase 
in annual revenues.

Senior  Notes  Offering—On  Sept.  1,  2016,  we  closed  our  inaugural 
offering of $400 million of senior unsecured notes at one of the lowest 
historical  initial  yields  (5.50  percent)  in  the  high  yield  energy  space. 
This offering added another arrow to our quiver and created additional 
available  capacity  on  our  revolving  credit  facility  which  ultimately 
gives us more flexibility for future dropdowns and potential M&A. We 
expect to be an investment grade debt issuer in the near future. 

2017—MUCH TO LOOK FORWARD TO

Moving into 2017, we believe things are looking up with respect 
to  the  energy  industry  as  a  whole.  From  what  we  see  and  hear,  our 
customers,  shippers,  drillers  and  end-users  are  more  positive  and 
looking optimistically toward the future.

On Jan. 3, 2017, TEP purchased Tallgrass Terminals—inclusive of 
two  organic  development  projects—and  the  operator  of  REX  from 
TDEV for $140 million. These two businesses bring about $17 million 
of cash flow to the table for TEP. 

The following are a few of the things we have to look forward to in 

2017 and beyond:

• Pony Express—

o We  are  working  to  add  additional  refineries  to  create  additional 

demand pull on the system.

o We are working on new joint tariffs to allow our shipper customers to 
ship competitively to the Gulf Coast should they choose to do so.
o We expect to have more capacity utilized (up to 100k+/bpd) on top of 
our  existing  contracted  capacity  as  drilling  resumes  and  oil  prices 
recover to healthier levels.

o We  remind  everyone  that  we  are  the  lowest-cost  alternative  to 
Cushing  from  the  Bakken,  the  DJ/Niobrara  and  the  Powder  River 
basins.

o We expect to add a lighter stream of condensate to our mix of prod-

ucts being shipped.

• REX—

o We  believe  our  recent  Zone  3  Capacity  Enhancement  project  may 
allow  for  even  more  volumes  to  become  available  to  our  shippers 
due to its well-engineered design. Stay tuned.

o Look  for  us  to  start  modifying  REX  zones  1  and  2  to  allow  them  to 
ship bi-directionally post-2019, along with zone 3—this will allow for 
many more revenue possibilities. 

o Although  still  more  than  two  and  one  half  years  away,  look  for  our 
re-contracting in zones 1 and 2 to take shape with a newly modified 
system.

o Finally, if the market warrants it—and we believe it does—look for us 
to optimize looping opportunities on REX in zone 3 over the next five 
years.  The  seven  interconnects  we  have  with  others  in  zone  3  are 
well in excess of zone 3’s current capacity of 2.6 Bcf/day.

o We  are  seeing  many  natural  gas  electric  generation  plants  being 
co-located  on  our  systems—TIGT,  Trailblazer  and  REX—and  we 
believe we will get our fair share of these demand-pull load plants in 
the future. In fact, our first large plant hook-up is underway. 

• NGL and Water Businesses

o NGL  pricing  was  destroyed  along  with  oil  prices  in  late  2015  and 
2016. Now that oil is recovering, we’re optimistic that our processing 
business  will  be  resilient  as  well.  We  are  capable  of  more  ethane 
recovery than anyone in the Powder River Basin with our cryogenic 
plant capabilities.

o Organic growth in our water business will continue. We will continue 
to  look  for  opportunities  to  acquire  systems  that  complement  our 
existing assets, and the strong relationships we have with our cus-
tomers will allow us to organically grow into the foreseeable future.

• M&A—Emphasis on Acquisitions

o As of right now, we have over $500 million of dry powder available to 
us  for  acquisitions.  We  are  conservatively  levered  at  ~3.0x  debt  to 
EBITDA  at  year-end  2016.  We  have  no  current  need  to  access  the 
equity markets. As always, this could change for the right opportunity. 
o Our management team has a rich history of successfully completing 
deals  that  benefit  Tallgrass.  In  fact,  we  have  completed  more  than 
$6.5 billion of acquisitions and growth projects over the last four and 
one half years. As always, we will be prudent in the acquisitions we 
pursue,  and  I’m  confident—knowing  my  team—that  we  will  con-
tinue our success in this area too. 

WE HAVE ONLY JUST BEGUN

  At  Tallgrass,  we  play  long  ball.  We’re  steady  in  the  face  of  short-
term movements in both the stock and commodities markets. We have 
our eye on the horizon, which means we’re constantly looking to create 
long-term value for our unitholders. We maintain an unwavering focus 
on  the  things  we  can  control,  and  we  manage  our  business  for  long-
term success. Going forward, Tallgrass has the right assets, the right 
contracts  with  the  right  counterparties,  the  right  balance  sheet  and 
ample liquidity to move our company forward and to meet our objec-
tives and your expectations. 

  Once  again,  in  2016  Tallgrass  Energy  delivered.  I  hope  that  each 
owner of TEP will join me in sincerely thanking the Tallgrass employ-
ees  for  their  continued  outstanding  effort.  In  addition  to  our  employ-
ees,  we  again  thank  our  supporters,  our  unitholders,  our  customers 
and  our  suppliers.  All  of  you  are  our  partners  too.  You  all  make  our 
future possible, and you make our future bright.

  On this date in 2017, we at TEP renew our commitment to you, our 
partners,  to  putting  forth  an  outstanding  effort  to  steward  our 
business;  to  grow  that  business;  to  expand  our  services;  and  most 
importantly,  to  translate  all  of  that  into  outstanding  and  sustainable 
investment returns.

Sincere regards,

• TIGT and Trailblazer

o We  remind  everyone  that  Trailblazer  remains  the  least  expensive 

route out of the Rockies; this is a clear competitive advantage.

(a) Indicated amounts presented for the twelve months ended December 31, 2013 are on a pro forma basis, which assumes that our initial public offering and related formation transactions, including bor-
rowings under our revolving credit facility, had closed on January 1, 2013. No cash distributions were paid with respect to the first quarter of 2013, and a prorated distribution of available cash was paid 
for the period from the closing of the IPO (May 17, 2013) through the end of the second quarter. Pro forma distributions were calculated using the minimum quarterly distribution for the first two quarters 
of 2013 and the increased distribution for the third and fourth quarters. Actual cash distributions for the twelve month period ending December 31, 2013, were $0.7547/unit. Pro forma interest expense 
(inclusive of commitment fees) for the twelve months ended December 31, 2013, was calculated by multiplying the actual cash interest cost for Q3 by three and adding the actual cash interest cost for 
Q4. Actual cash interest cost for the twelve month period ended December 31, 2013, was $3,555,000.

Management believes the pro forma presentation of distributable cash flow, distribution coverage and net income per limited partner unit provides investors with useful information to compare our historical 
financial results to future periods. These pro forma financial measures are presented for illustrative purposes only and are not necessarily indicative of the operating results or the financial position that 
would have been achieved had the initial public offering and related formation transactions been consummated on January 1, 2013 or of the results that may be obtained in the future.

indirectly controls our general partner. In connection with our initial public offering on May 17, 2013 (the "IPO"), Tallgrass
Development contributed to us 100% of the membership interests in TIGT and TMID. Since then, we have acquired the 
following additional assets from Tallgrass Development: (1) in April 2014, a 100% membership interest in Trailblazer, (2) in 
three separate transactions, the most recent of which was effective on January 1, 2016, a 98% membership interest in Pony 
Express, and (3) in January 2017, a 100% membership interest in NatGas and Terminals. In addition, in May 2016 Tallgrass
Development assigned us its right to purchase a 25% membership interest in Rockies Express from a unit of Sempra U.S. Gas 
and Power ("Sempra") pursuant to the purchase agreement originally entered into between Tallgrass Development's wholly-
owned subsidiary and Sempra in March 2016. Tallgrass Development continues to own a 50% interest in Rockies Express and a 
2% interest in Pony Express.

Pursuant to an Omnibus Agreement entered into upon the closing of our IPO, among us, TEP GP, Tallgrass Development 

and Tallgrass Energy Holdings (the "TEP Omnibus Agreement"), Tallgrass Development granted us a right of first offer to 
acquire certain assets held by Tallgrass Development at the time of our IPO, which we refer to as the Retained Assets, if 
Tallgrass Development decides to sell such assets. The Retained Assets include Tallgrass Development's 50% interest in 
Rockies Express and Tallgrass Development's remaining 2% noncontrolling interest in Pony Express. Tallgrass Development is 
otherwise under no obligation to offer to sell us additional assets or to pursue acquisitions jointly with us, and we are under no 
obligation to buy any assets from Tallgrass Development or pursue any such joint acquisitions. However, given the significant 
economic interest in us held by Tallgrass Development and its affiliates, including Tallgrass Energy Holdings, we believe 
Tallgrass Development will be incentivized to offer us the opportunity to acquire the Retained Assets.

Acquisitions

The acquisition of midstream assets and businesses that are strategic and complementary to our existing operations 
constitutes an integral component of our business strategy and growth objectives. Such assets and businesses include crude oil 
transportation, storage and terminalling assets, natural gas transportation, storage and processing assets and water business 
services assets and other energy assets that have characteristics and provide opportunities similar to our existing business lines 
and enable us to leverage our assets, knowledge and skill sets. Below are summaries of significant acquisitions we completed in 
2016 and in January 2017. See Note 4 – Acquisitions to our Consolidated Financial Statements in Item 8.—Financial 
Statements and Supplementary Data for a full discussion regarding our acquisition activities.

Additional Membership Interest in Pony Express. Effective January 1, 2016, we acquired an 
additional 31.3% membership interest in Pony Express in exchange for cash consideration of $475
million and 6,518,000 TEP common units (valued at approximately $268.6 million based on the December 31, 2015 
closing price of our common units), issued to Tallgrass Development, for total consideration of approximately $743.6
million. The transaction increased our aggregate membership interest in Pony Express to 98%.

Rockies Express Pipeline LLC. Effective May 6, 2016, we acquired a 25% membership interest in Rockies Express 
from Sempra for cash consideration of approximately $436 million, or an enterprise value of approximately $1.08 
billion when adjusted for our proportionate share of outstanding indebtedness at Rockies Express as of the acquisition 
date.

Additional Membership Interest in Water Solutions. On July 1, 2016, we acquired the remaining 8% noncontrolling 
equity interest in Water Solutions and additional interests in Water Solutions' subsidiaries from Regency Investments I, 
LLC and BSEG Water Group LLC for total cash consideration of $6.0 million. Subsequent to the closing of the 
transaction, our aggregate membership interest in Water Solutions is 100%.

Terminals and NatGas. Effective January 1, 2017, we acquired 100% of the issued and outstanding membership 
interests in Terminals and 100% of the issued and outstanding membership interests in NatGas from Tallgrass
Development for total cash consideration of $140 million.

Competition

All of our businesses face strong competition for acquisitions and development of new projects from both established and 

start-up companies. Competition may increase the cost to acquire existing facilities or businesses and may result in fewer 
commitments and lower returns for new pipelines or other development projects. Our competitors may have greater financial 
resources than we possess or may be willing to accept lower returns or greater risks. Competition differs by region and by the 
nature of the business or the project involved.

8

Additionally, pending and future construction projects, if and when brought online, may also compete with our crude oil 

transportation, storage and terminalling services, natural gas transportation, storage and processing services and water 
transportation, gathering and disposal services. Further, natural gas as a fuel, and fuels derived from crude oil, compete with 
other forms of energy available to users, including electricity, coal, other liquid fuels and alternative energy. Increased demand 
for such forms of energy at the expense of natural gas or fuels derived from crude oil could lead to a reduction in demand for 
our services. Moreover, several other factors may influence the demand for natural gas and crude oil which in turn influences 
the demand for our services, including price changes, the availability of natural gas and crude oil and other forms of energy, the 
level of business activity, conservation, legislation and governmental regulations, weather, and the ability to convert to 
alternative fuels.

Pony Express encounters competition in the crude oil transportation business. A number of pipeline companies compete 
with Pony Express to service takeaway volumes in markets that Pony Express currently serves, including pipelines owned and 
operated by Spectra Energy, Sinclair, Plains All American, Suncor, SemGroup, Magellan Midstream Partners, Anadarko, NGL
Energy Partners, Energy Transfer Partners, and Enbridge Energy Partners. Pony Express also competes with rail facilities, 
which can provide more delivery optionality to crude oil producers and marketers looking to capitalize on basis differentials
between two primary crude oil price benchmarks (West Texas Intermediate Crude and Brent Crude), and with refineries that 
source barrels in areas served by Pony Express. In addition, Terminals encounters competition in the crude oil storage and 
terminalling business from similar facilities owned by Arc Logistics Partners LP, Magellan Midstream Partners, and NGL
Energy Partners, that provide similar services near its Buckingham Terminal.

Our principal competitors in our natural gas transportation and storage business include companies that own major natural 
gas pipelines, such as Spectra Energy, Wyoming Interstate Company, LLC, Colorado Interstate Gas Company, LLC, Cheyenne 
Plains Gas Pipeline Company, LLC, Northern Natural Gas Company, and Southern Star Central Gas Pipeline, Inc., some of 
whom also have existing storage facilities connected to their transportation systems that compete with our storage facilities. In 
addition to this competition, which is primarily comprised of other pipeline companies that transport gas out of the Rocky 
Mountain region, Trailblazer also delivers gas into a very competitive marketplace that receives gas from the developing shale 
plays like the Bakken, Marcellus and Utica. As these supplies increase, it reduces the need for traditional Rockies gas 
production that is accessible from Trailblazer.

We also experience competition in the natural gas processing business. Our principal competitors for processing business 
include other facilities that service our supply areas, such as the other regional processing and treating facilities in the greater 
Powder River Basin which include plants owned and operated by Kinder Morgan, Inc., which we refer to as Kinder Morgan,
ONEOK Partners, LP, Western Gas Partners, LP, Williams Partners L.P. and Meritage Midstream Services II, LLC. In addition, 
due to the competitive nature of the liquids-rich plays in the Wind River Basin and Powder River Basin, it is possible that one 
of our competitors could build additional processing facilities that service our supply areas. Further, we experience competition 
in the water business services. Our principal competitors in such business are other midstream companies, such as NGL Energy
Partners, who compete with Water Solutions in areas of concentrated production activity.

Regulatory Environment

Federal Energy Regulatory Commission

We provide open-access interstate transportation service on our natural gas transportation systems pursuant to tariffs

approved by the FERC. As interstate transportation and storage systems, the rates, terms of service and continued operations of 
the Rockies Express Pipeline, the TIGT System, and the Trailblazer Pipeline are subject to regulation by the FERC, under 
among other statutes, the Natural Gas Act of 1938, or NGA, the Natural Gas Policy Act of 1978, or the NGPA, and the Energy
Policy Act of 2005, or EPAct 2005. The rates and terms of service on the Pony Express System are subject to regulation by the 
FERC under the Interstate Commerce Act, or the ICA, and the Energy Policy Act of 1992. We provide interstate transportation 
service on the Pony Express System pursuant to tariffs on file with the FERC. Our NGL pipeline that interconnects with 
Overland Pass Pipeline is leased to a third party who has obtained a waiver for itself from the FERC from the tariff, filing and 
reporting requirements of the ICA, and our NGL pipeline that interconnects with the ONEOK's Bakken NGL Pipeline is leased 
to a third party who is obligated to operate the leased pipeline in conformance with the ICA as a FERC regulated NGL pipeline.

The FERC has jurisdiction over, among other things, the construction, ownership and commercial operation of pipelines 
and related facilities used in the transportation and storage of natural gas in interstate commerce, including the modification, 
extension, enlargement and abandonment of such facilities. The FERC also has jurisdiction over the rates, charges and terms 
and conditions of service for the transportation and storage of natural gas in interstate commerce. The FERC's authority over 
interstate crude oil pipelines is less broad than its authority over interstate natural gas pipelines and includes rates, rules and 
regulations for service, the form of tariffs governing service, the maintenance of accounts and records, and depreciation and 
amortization policies.

9

The rates and terms for access to interstate natural gas pipeline transportation services are subject to extensive regulation 

and the FERC has undertaken various initiatives to increase competition within the natural gas industry. As a result of these 
initiatives, interstate natural gas transportation and marketing entities have been substantially restructured to remove barriers 
and practices that historically limited non-pipeline natural gas sellers, including producers, from competing effectively with 
interstate pipelines for sales to local distribution companies and large industrial and commercial customers. The FERC's 
regulations require, among other things, that interstate natural gas pipelines provide firm and interruptible transportation service 
on an open access basis, provide internet access to current information about available pipeline capacity and other relevant 
information, and permit pipeline shippers under certain circumstances to release contracted transportation and storage capacity 
to other shippers, thereby creating secondary markets for such services. The result of the FERC's initiatives has been to 
eliminate interstate natural gas pipelines' historical role of providing bundled sales service of natural gas and to require 
pipelines to offer unbundled storage and transportation services on a not unduly discriminatory or preferential basis. The rates 
for such transportation and storage services are subject to the FERC's ratemaking authority, and the FERC exercises its 
authority by applying cost-of-service principles to limit the maximum and minimum levels of tariff-based recourse rates; 
however, it also allows for discounted or negotiated rates as an alternative to cost-based rates and may grant market-based rates 
in certain circumstances, typically with respect to storage services. The FERC regulations also restrict interstate natural gas 
pipelines from sharing certain transportation or customer information with marketing affiliates and require that the transmission 
function personnel of interstate natural gas pipelines operate independently of the marketing function personnel of the pipeline 
or its affiliates.

FERC; Market Behavior Rules; Posting and Reporting Requirement; Other Enforcement Authorities

EPAct 2005, among other matters, amended the NGA to add an anti-manipulation provision that makes it unlawful for any 

entity to engage in prohibited behavior in contravention of rules and regulations to be prescribed by the FERC and, 
furthermore, provides the FERC with additional civil penalty authority. The FERC adopted rules implementing the anti-
manipulation provision of EPAct 2005 that make it unlawful for any entity, directly or indirectly in connection with the 
purchase or sale of natural gas transportation services subject to the jurisdiction of the FERC to (1) use or employ any device, 
scheme or artifice to defraud; (2) to make any untrue statement of material fact or omit to make any such statement necessary 
to make the statements made not misleading; or (3) to engage in any act or practice that operates as a fraud or deceit upon any 
person.

These anti-manipulation rules apply to interstate gas pipelines and storage companies and intrastate 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" gas sales, purchases or transportation subject to FERC jurisdiction. EPAct 2005 also amended 
the NGA and the NGPA to give the FERC authority to impose civil penalties for violations of these statutes of more than $1 
million per day per violation. In connection with this enhanced civil penalty authority, the FERC issued policy statements on 
enforcement to provide guidance regarding the enforcement of the statutes, orders, rules and regulations it administers, 
including factors to be considered in determining the appropriate enforcement action to be taken. Should we fail to comply with 
all applicable FERC-administered statutes, rule, regulations and orders, we could be subject to substantial penalties and fines, 
including the disgorgement of unjust profits.

EPAct 2005 also amended the NGA to authorize the FERC to facilitate price transparency in markets for the sale or 
transportation of physical natural gas in interstate commerce. The FERC has taken steps to enhance its market oversight and 
monitoring of the natural gas industry by adopting rules that (1) require buyers and sellers of annual quantities of 2,200,000 
MMBtu or more of gas in any year to report by May on the aggregate volumes of natural gas they purchased or sold at 
wholesale in the prior calendar year; (2) report whether they provide prices to any index publishers and, if so, whether their 
reporting complies with the FERC's policy statement on price reporting; and (3) increase the Internet posting obligations of 
interstate pipelines.

In addition, the Commodity Futures Trading Commission, or CFTC, is directed under the Commodities Exchange Act, or 
CEA, to prevent price manipulations for the commodity and futures markets, including the energy futures markets. Pursuant to 
the Dodd-Frank Wall Street Reform and Consumer Protection Act, or Dodd-Frank Act, in July 2010 and other authority, the 
CFTC has adopted anti-market manipulation regulations that prohibit fraud and price manipulation in the commodity and 
futures markets. The CFTC also has statutory authority to seek civil penalties of up to the greater of more than $1 million or 
triple the monetary gain to the violator for violations of the anti-market manipulation sections of the CEA.

Further, the Federal Trade Commission, or FTC, has the authority under the Federal Trade Commission Act, or FTCA, and 

the Energy Independence and Security Act of 2007, or EISA, to regulate wholesale petroleum markets. The FTC has adopted 
anti-market manipulation rules, including prohibiting fraud and deceit in connection with the purchase or sale of certain 
petroleum products, and prohibiting omissions of material information which distort or are likely to distort market conditions 
for such products. In addition to other enforcement powers it has under the FTCA, the FTC can sue violators under EISA and 
request that a court impose fines of more than $1 million per violation per day.

10

The FERC also has the authority under the ICA to regulate the interstate transportation of petroleum on common carrier 

pipelines, including whether a pipeline's rates or rules and regulations for service are "just and reasonable." Among other 
enforcement powers, FERC can order prospective rate changes, suspend the effectiveness of rates, and order reparations for 
damages. In addition, the ICA imposes potential criminal liability for certain violations of the statute. 

Certain Outstanding Notices Issued by the FERC

FERC Advanced Notice of Proposed Rulemaking, Revisions to Indexing Policies and Page 700 of FERC Form No. 6, 

Docket No. RM17-1-000

On November 2, 2016, the FERC issued an Advanced Notice of Proposed Rulemaking, under which the FERC is 

proposing changes to its regulation of oil pipelines in two different areas: (1) its policies regarding the permissible scope of rate 
increases based on its annual issuance of changes to the generic oil pipeline index, based on specific pipelines' earnings or their 
specific changes to costs; and (2) the reporting requirements for page 700 of FERC Form No. 6, Annual Report of Oil Pipeline 
Companies. The FERC's Advanced Notice of Proposed Rulemaking does not propose specific regulations, and may be 
followed by a Notice of Proposed Rulemaking proposing specific regulations or a Policy Statement announcing new or 
changed policies. Initial comments to such notice were required to be submitted by January 19, 2017. 

Inquiry Regarding the FERC's Policy for Recovery of Income Tax Costs

On December 15, 2016, the FERC issued a Notice of Inquiry regarding the FERC's policy for recovery of income tax costs 

in pipeline cost of service rates. The FERC is seeking comments regarding how to address any double recovery resulting from 
the FERC's current income tax allowance and rate of return policies. This Notice of Inquiry follows the U.S. Court of Appeals
for the District of Columbia Circuit holding in United Airlines, Inc., et al. v. FERC that the FERC failed to demonstrate that 
there is no double recovery of taxes for a partnership pipeline as a result of the income tax allowance and return on equity 
determined pursuant to the discounted cash flow methodology. The FERC has set a deadline for initial comments to be 
submitted by March 8, 2017.

Certain of our Dockets at the FERC

Rockies Express Zone 3 Capacity Enhancement Project

On March 31, 2015 in Docket No. CP15-137-000, Rockies Express filed with the FERC an application for authorization to 
construct and operate (1) three new mainline compressor stations located in Pickaway and Fayette Counties, Ohio and Decatur 
County, Indiana; (2) additional compression at one existing compressor station in Muskingum County, Ohio; and (3) certain 
ancillary facilities. As proposed, the facilities would increase the Rockies Express Zone 3 east-to-west mainline capacity by 0.8 
Bcf/d. Pursuant to the FERC's obligations under the National Environmental Policy Act, FERC staff issued an Environmental 
Assessment for the project on August 31, 2015. On February 25, 2016, the FERC issued a Certificate of Public Convenience 
and Necessity authorizing Rockies Express to proceed with the project. On March 14, 2016, Rockies Express commenced 
construction of the project facilities. The project was placed in-service for the 0.8 Bcf/d on January 6, 2017.

Rockies Express Seneca Lateral Facilities Conversion

On March 2, 2015 in Docket No. CP15-102-000, Rockies Express filed with the FERC an application for (1) authorization 

to convert certain existing and operating pipeline and compression facilities located in Noble and Monroe Counties, Ohio 
(Seneca Lateral Facilities described in Docket Nos. CP13-539-000 and CP14-194-000) from NGPA Section 311 authority to 
NGA Section 7 jurisdiction, and (2) issuance of a certificate of public convenience and necessity authorizing Rockies Express 
to operate and maintain the Seneca Lateral Facilities. On April 7, 2016, the FERC issued a Certificate to Rockies Express 
granting its requested authorizations and on June 1, 2016 Rockies Express commenced NGA service on the Seneca Lateral.

TIGT 2015 General Rate Case Filing

On October 30, 2015, TIGT filed a general rate case with the FERC pursuant to Section 4 of the NGA. The rate case 
proposed a general system-wide increase in the maximum tariff rates for all firm and interruptible services offered by TIGT. In 
addition, TIGT proposed certain changes to the transportation rate design of its system to replace the current rate zone structure 
with a single "postage stamp" rate. TIGT also proposed new incremental charges, including (i) a charge for deliveries made to 
points without certain electronic flow measurement equipment, and (ii) a Cost Recovery Mechanism ("CRM") charge to 
completely or partially reimburse TIGT for certain expenses and costs it incurs to comply with anticipated new PHMSA and 
EPA regulations. TIGT also proposed to replace its fixed fuel and lost and unaccounted for ("FL&U") charge with a FL&U 
tracker that would compensate TIGT for its actual FL&U expenses and adjust each year to reflect the previous period's under/
over collection and the forecasted FL&U expense for the upcoming period. TIGT also proposed to implement a power cost 
tracker to recover the actual power costs incurred by TIGT to power its compressors. Finally, TIGT proposed certain revisions 
to its FERC Gas Tariff addressing a number of other rate and non-rate matters. Under the NGA and the FERC's regulations, 
TIGT's shippers and other interested parties, including the FERC's Trial Staff, have a right to challenge any aspect of TIGT's
rate case filing. Accordingly, numerous TIGT customers protested aspects of TIGT's NGA Section 4 rate filing.

11

On November 30, 2015, the FERC issued an order accepting and suspending the proposed rates and a majority of the 
proposed tariff records to be effective upon motion May 1, 2016, subject to refund, certain modifications to TIGT's proposed 
CRM charge, and the outcome of an evidentiary hearing before a FERC Administrative Law Judge (the "TIGT Suspension 
Order"). In the TIGT Suspension Order, the FERC also accepted two tariff records related to force majeure events and 
reservation charge crediting to be effective December 1, 2015, subject to certain modifications. On December 21, 2015, TIGT
made a compliance filing with the FERC to modify TIGT's proposed CRM charge and update the tariff records related to force
majeure events and reservation charge crediting as directed by the FERC in the TIGT Suspension Order. No comments or 
protests were filed in response to the compliance filing and the FERC accepted the compliance filing on February 1, 2016. On 
March 31, 2016, the FERC issued an order denying certain rehearing requests pertaining to the proposed CRM charge and 
removed from hearing the non-rate issues related to proposed pro forma tariff records, placing the non-rate issues under a 
separate review process, and allowing interveners further opportunity to comment on the pro forma tariff. TIGT and certain 
intervenors have since filed additional information and/or comments with respect to the proposed pro forma tariff. On February 
3, 2017, the FERC accepted TIGT’s pro forma tariff records, subject to conditions, and directed TIGT to file the actual tariff
records within 30 days.

On June 8, 2016, TIGT filed an Offer of Settlement ("TIGT Rate Case Settlement") with the FERC, which resolved all 
issues set for hearing. On July 14, 2016, the presiding Administrative Law Judge certified the TIGT Rate Case Settlement to the 
FERC, finding that settlement was uncontested, presented no issues of first impression, had no FERC policy implications, and 
appeared to be just, reasonable and in the public interest. On November 2, 2016, the FERC issued an order approving the TIGT
Rate Case Settlement, finding that it appeared to be fair and reasonable and in the public interest. The FERC also directed TIGT
to file revised tariff records to implement the TIGT Rate Case Settlement, which TIGT filed, and the FERC subsequently 
approved on December 23, 2016. The November 2, 2016 order also terminated all matters in the TIGT rate case, apart from the 
non-rate issues related to the pro forma tariff which remain pending before the FERC. Per the terms of the TIGT Rate Case 
Settlement, TIGT is required to file a new general rate case on May 1, 2019 (provided that such rate case is not pre-empted by a 
pre-filing settlement), and no Supporting/Non-Contesting Participant, as defined in the TIGT Rate Case Settlement, is 
permitted to, inter alia, file to change the settlement rates or any other provisions set forth in the TIGT Rate Case Settlement 
prior to May 1, 2019.

Pipeline and Hazardous Materials Safety Administration

We are also subject to safety regulations imposed by PHMSA, including those regulations requiring us to develop and 
maintain integrity management programs to comprehensively evaluate certain areas along our pipelines and take additional 
measures to protect pipeline segments located in areas, which are referred to as high consequence areas, or HCAs, where a leak 
or rupture could potentially do the most harm.

In January 2012, the Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011, or The Pipeline Safety Act of 
2011, which amended the Pipeline Safety Improvement Act of 2002, increased penalties for violations of safety laws and rules, 
among other matters, and may result in the imposition of more stringent regulations in the next few years. This legislation also 
requires the U.S. Department of Transportation to study and report to Congress on other areas of pipeline safety, including 
expanding the reach of the integrity management regulations beyond high consequence areas, but restricts the U.S. Department 
of Transportation from promulgating expanded integrity management rules during the review period and for a period following 
submission of its report to Congress unless the rulemaking is needed to address a present condition that poses a risk to public 
safety, property or the environment. PHMSA issued a final rule effective October 25, 2013 that implemented aspects of the new 
legislation. Among other things, the final rule increases the maximum civil penalties for violations of pipeline safety statutes or 
regulations, broadens PHMSA's authority to submit information requests, and provides additional detail regarding PHMSA's 
corrective action authority. In addition, the Protecting our Infrastructure of Pipelines and Enhancing Safety Act of 2016, or 
PIPES Act, reauthorized PHMSA's oil and gas pipeline programs through 2019 and gave PHMSA power to issue emergency
orders upon finding an imminent hazard, required PHMSA to issue safety standards for underground natural gas storage 
facilities, set deadlines for conducting post-inspection briefings and making findings, required liquid pipeline operators to 
undertake new safety measures, and required certain updates to the PHMSA website.

Additionally, PHMSA is also currently considering changes to its regulations. On December 14, 2016, PHMSA issued an
interim final rule, or IFR, that addresses safety issues related to downhole facilities, including well integrity, well bore tubing, and
casing at underground natural gas storage facilities. The IFR incorporates by reference two of the American Petroleum Institute’s
Recommended Practice standards and mandates certain reporting requirements for operators of underground natural gas storage
facilities. Operators of natural gas storage facilities have one year from January 18, 2017, the effective date of the IFR, to implement
this first set of PHMSA regulations governing underground storage fields. On January 13, 2017, PHMSA finalized new hazardous
liquid pipeline safety regulations. Among other things, the final rule requires additional event-driven and periodic inspections,
requires the use of leak detection systems on all hazardous liquid pipelines, modifies repair criteria, and requires certain pipelines
12

to eventually accommodate in-line inspection tools. Because the rule was finalized at the end of the Obama Administration, the
rule is subject to a regulatory freeze pending review by the Trump Administration, unless exempted due to health and safety
considerations. Assuming the rule survives the review process or is exempted from the regulatory freeze, the rule will become
effective six months after its publication in the Federal Register, although certain provisions of the Final Rule will have longer
compliance periods. Also, on April 8, 2016, PHMSA published a notice of proposed rule-making, or NPRM, addressing natural
gas transmission and gathering lines. The proposed rule would include changes to existing integrity management requirements
and would expand assessment and repair requirements to pipelines in areas with medium population densities (referred to as
Moderate Consequence Areas or MCAs), along with other changes. This NPRM builds on an Advisory Bulletin PHMSA issued
in May 2012, which advised pipeline operators of anticipated changes in annual reporting requirements and that if they are relying
on design, construction, inspection, testing, or other data to determine the pressures at which their pipelines should operate, the
records of that data must be traceable, verifiable and complete. Locating such records and, in the absence of any such records,
verifying maximum pressures through physical testing (including hydrotesting) or modifying or replacing facilities to meet the
demands of such pressures, could significantly increase our costs. TIGT continues to investigate and, when necessary, report to
PHMSA the miles of pipeline for which it has incomplete records for maximum allowable operating pressure, or MAOP. We are
currently undertaking an extensive internal record review in view of the anticipated PHMSA annual reporting requirements.
Additionally, failure to locate such records or verify maximum pressures could result in reductions of allowable operating pressures,
which would reduce available capacity on our pipelines. At the state level, several states have passed legislation or promulgated
rulemaking dealing with pipeline safety. There can be no assurance as to the amount or timing of future expenditures for pipeline
integrity regulation, and actual future expenditures may be different from the amounts we currently anticipate. Regulations, changes
to regulations or an increase in public expectations for pipeline safety may require additional reporting, the replacement of some
of our pipeline segments, the addition of monitoring equipment and more frequent inspection or testing of our pipeline facilities.
Any repair, remediation, preventative or mitigating actions may require significant capital and operating expenditures.

Pipeline Integrity Issues

The ultimate costs of compliance with the integrity management rules are difficult to predict. Changes such as advances of 

in-line inspection tools, identification of additional threats to a pipeline's integrity and changes to the amount of pipe 
determined to be located in HCAs or expansion of integrity management requirements to areas outside of HCAs can have a 
significant impact on the costs to perform integrity testing and repairs. We will continue pipeline integrity testing programs to 
assess and maintain the integrity of our existing and future pipelines as required by the U.S. Department of Transportation
regulations. The results of these tests could cause us to incur significant and unanticipated capital and operating expenditures 
for repairs or upgrades deemed necessary to ensure the continued safe and reliable operation of our pipelines, which 
expenditures could be material.

From time to time, our pipelines may experience integrity issues. These integrity issues may cause explosions, fire, damage 
to the environment, damage to property and/or personal injury or death. In connection with these incidents, we may be sued for 
damages caused by an alleged failure to properly mark the locations of our pipelines and/or to properly maintain our pipelines. 
Depending upon the facts and circumstances of a particular incident, state and federal regulatory authorities may seek civil and/
or criminal fines and penalties and we may also be subject to private civil liability for such matters. 

Trailblazer

Trailblazer is currently operating at less than its current MAOP, public notice of which was first provided in June 2014. As
a result of smart tool surveys in 2014, Trailblazer has identified approximately 25 - 35 miles of pipe that will likely need to be 
repaired or replaced in order for the pipeline to operate at its MAOP of 1,000 pounds per square inch across all segments of the 
Trailblazer Pipeline. Such repair or replacement will likely occur over a period of years, depending upon the remediation and 
repair plan implemented by Trailblazer. Segments of the Trailblazer Pipeline that require full replacement could cost as much as 
$2.7 million per mile and repair costs on sections of the pipeline that do not require full replacement are expected to be less on 
a per mile basis. The current pressure reduction is not expected to prevent Trailblazer from fulfilling its firm service obligations 
at existing subscription levels and to date it has not had a material adverse financial impact on us.

With respect to the approximately 25 - 35 miles of pipe that has been identified, Trailblazer completed 32 excavation digs 
in 2015 at an aggregate cost of approximately $1.3 million. During 2016, Trailblazer completed additional excavation digs and 
replaced approximately 8 miles of pipe at an aggregate cost of approximately $19.0 million. Trailblazer is currently exploring 
all possible cost recovery options to recover such out of pocket costs, including recovery through a general rate increase, 
negotiated rate agreements with its customers, or other FERC-approved recovery mechanisms. 

13

In connection with our acquisition of the Trailblazer Pipeline, TD agreed to contractually indemnify TEP for any out of 
pocket costs incurred between April 1, 2014 and April 1, 2017 related to repairing or remediating the Trailblazer Pipeline, to the 
extent that such actions are necessitated by external corrosion caused by the pipeline's disbonded Hi-Melt CTE coating. The
contractual indemnity provided by TD is capped at $20 million and is subject to an annual $1.5 million deductible. In 
connection with the 2016 repairs and remediation on the Trailblazer Pipeline, TEP has received $17.9 million from TD pursuant 
to the contractual indemnity.

Pony Express

In connection with certain crack tool runs on the Pony Express System completed in 2015 and 2016, Pony Express 

completed approximately $9.8 million of remediation in 2016 for anomalies identified on the Pony Express System associated 
with portions of the pipeline that were converted from natural gas to crude oil service, and expects to complete additional 
remediation in 2017 on the Pony Express System of approximately $9 million.

Environmental, Health and Safety Matters

General

The ownership, operation and expansion of our assets are subject to federal, state and local laws, regulations and potential 

liabilities arising under or relating to the protection or preservation of the environment, natural resources and human health. 
These laws and regulations can restrict or impact our business activities in many ways, such as restricting the way we can 
handle or dispose of our wastes, requiring remedial action to mitigate pollution conditions that may be caused by our operations 
or that are attributable to former operations, regulating future construction activities to mitigate harm to threatened or 
endangered species, wetlands and migratory birds, and requiring the installation and operation of pollution control or seismic 
monitoring equipment. The cost of complying with these laws and regulations can be significant, and we expect to incur 
significant compliance costs in the future as new, more stringent requirements are adopted and implemented. 

Failure to comply with existing environmental laws, regulations, permits, approvals or authorizations or to meet the 

requirements of new environmental laws, regulations or permits, approvals and authorizations may trigger a variety of 
administrative, civil and criminal enforcement measures, including the assessment of monetary penalties and/or temporary or 
permanent interruptions in our operations that could influence our business, financial position, results of operations and 
prospects. Certain environmental statutes impose strict joint and several liability for costs required to clean up and restore sites 
where hazardous substances, hydrocarbons or wastes have been disposed or otherwise released. The costs and liabilities 
resulting from a failure to comply with environmental laws and regulations could negatively affect our business, financial 
position, results of operations and prospects. Moreover, it is not uncommon for neighboring landowners and other third parties 
to file claims for personal injury and property damage allegedly caused by the release of hazardous substances, hydrocarbons or 
other waste products into the environment.

In addition, we have agreed to a number of conditions in our environmental permits, approvals and authorizations that 
require the implementation of environmental habitat restoration, enhancement and other mitigation measures that involve, 
among other things, ongoing maintenance and monitoring. Governmental authorities may require, and community groups and 
private persons may seek to require, additional mitigation measures in the future to further protect ecologically sensitive areas 
where we currently operate, and would operate in the future, and we are unable to predict the effect that any such measures 
would have on our business, financial position, results of operations or prospects.

We are also subject to the requirements of the Occupational Health and Safety Act, or OSHA, the Pipeline Safety Act and 

other comparable federal and state statutes. In general, we expect that we may have to increase expenditures in the future to 
comply with higher industry and regulatory safety standards. Such increases in expenditures could become significant over 
time.

Historically, our total expenditures for environmental control measures and for remediation have not been significant in 
relation to our consolidated financial position or results of operations. It is reasonably likely, however, that the long-term trend 
in environmental legislation and regulations will continue towards more restrictive standards. Compliance with these standards 
is expected to increase the cost of conducting business.

Air Emissions

Our operations are subject to the federal Clean Air Act, or CAA, and comparable state laws and regulations. These laws 
and regulations regulate emissions of air pollutants from various industrial sources, including natural gas processing plants and 
compressor stations, and also impose various monitoring and reporting requirements. Such laws and regulations may require 
that we obtain pre-approval for the construction or modification of certain projects or facilities expected to produce air 
emissions or result in the increase of existing air emissions (including GHG emissions, as discussed below), obtain and strictly 
comply with air permits containing various emissions and operational limitations and/or install emission control equipment. We
may be required to incur certain capital expenditures in the future for air pollution control equipment and technology in 
connection with obtaining and maintaining operating permits and approvals for air emissions.

The EPA finalized a rule, effective August 2, 2016, under the New Source Performance Standard Program, or NSPS 
Program, to limit methane emissions from the oil and gas and transmission sectors. The rule sets additional emissions limits for 
volatile organic compounds and regulates methane emissions for new and modified sources in the oil and gas industry. The EPA
also finalized a rule regarding the alternative criteria for aggregating multiple small surface sites into a single source for air-
quality permitting purposes. Also, effective January 17, 2017 the Bureau of Land Management of the U.S. Department of the 
Interior, or BLM, imposed new rules to reduce venting, flaring and leaks during oil and natural gas production activities on 
onshore Federal and Indian lands. 

Developments in GHG Regulations

Methane, a primary component of natural gas, and carbon dioxide, a byproduct of the burning of natural gas and products 
produced from crude oil, are examples of GHGs. The EPA has determined that the emission of GHGs present an endangerment 
to public health and the environment because emissions of such gases contribute to the warming of the Earth's atmosphere and 
other climatic changes. Various laws and regulations exist or are under development that seek to regulate the emission of such 
GHGs, including the EPA programs to control GHG emissions and state actions to develop statewide or regional programs. In 
recent years, the U.S. Congress has considered, but not adopted, legislation to reduce emissions of GHGs. There have also been 
efforts to regulate GHGs at an international level, most recently in the Paris Agreement, which was signed on April 22, 2016 by 
175 countries, including the United States. The Paris Agreement will require countries to review and "represent a progression" 
in their intended, nationally-determined contributions, which set GHG emission reduction goals, every five years beginning in 
2020.

Because our operations, including our compressor stations, emit various types of GHGs, primarily methane and carbon 

dioxide, such new legislation or regulation could increase our costs related to operating and maintaining our facilities. 
Depending on the particular new law, regulation or program adopted, we could be required to incur capital expenditures for 
installing new emission controls on our facilities, acquire permits or other authorizations for emissions of GHGs from our 
facilities, acquire and surrender allowances for our GHG emissions, pay taxes related to our GHG emissions and administer 
and manage a GHG emissions program. We are not able at this time to estimate such increased costs; however, as is the case 
with similarly situated entities in the industry, they could be significant to us. While we may be able to include some or all of 
such increased costs in the rates charged by our pipelines, such recovery of costs in all cases is uncertain and may depend on 
events beyond our control including the outcome of future rate proceedings before the FERC and the provisions of any final 
legislation or other regulations. Similarly, while we may be able to recover some or all of such increased costs in the rates 
charged by our processing facilities, such recovery of costs is uncertain and may depend on the terms of our contracts with our 
customers. In addition, new laws, regulations, or programs adopted could also impact our customers' operations or the overall 
demand for fossil fuels. Any of the foregoing could have an adverse effect on our business, financial position, results of 
operations and prospects.

Regulation of Hydraulic Fracturing

A sizeable portion of the hydrocarbons we transport, process, and store comes from hydraulically fractured wells. 
Hydraulic fracturing is an important and common practice that is used to stimulate production of hydrocarbons from tight 
formations. The process typically involves the injection of water, sand and a small percentage of chemicals under pressure into 
the formation to fracture the surrounding rock and stimulate production. The process is regulated by state agencies, typically 
the state's oil and gas commission; however, the EPA has asserted federal regulatory authority over certain hydraulic fracturing 
activities involving diesel under the federal Safe Drinking Water Act, or SDWA and has released draft permitting guidance for 
hydraulic fracturing activities that use diesel in fracturing fluids in those states where the EPA is the permitting authority. A
number of federal agencies, including the EPA and the U.S. Department of Energy, are analyzing, or have been requested to 
review, a variety of environmental issues associated with hydraulic fracturing. In addition, some states, including those in 
which we operate, have adopted, and other states are considering adopting, regulations that could impose more stringent 
disclosure and/or well construction requirements on hydraulic fracturing operations. Other states, including states in which we 
operate, have restrictions on produced water storage from hydraulic fracturing operations and the operation of produced water 
disposal wells. Local government also may seek to adopt ordinances within their jurisdictions regulating the time, place and 

15

manner of drilling activities in general or hydraulic fracturing activities in particular, and in some cases, may seek to ban 
hydraulic fracturing entirely. Some state and local authorities have considered or imposed new laws and rules related to 
hydraulic fracturing, including temporary or permanent bans, additional permit requirements, operational restrictions and 
chemical disclosure obligations on hydraulic fracturing in certain jurisdictions or in environmentally sensitive areas. 

 If new laws or regulations that significantly restrict hydraulic fracturing are adopted, such laws could make it more 
difficult or costly for our customers to perform fracturing to stimulate production from tight formations. Restrictions on 
hydraulic fracturing could also reduce the volume of crude oil, natural gas, and NGLs that our customers produce, and could 
thereby adversely affect our revenues and results of operations.

Hazardous Substances and Waste

Our operations are subject to environmental laws and regulations relating to the management and release of hazardous 
substances, nonhazardous and hazardous wastes and petroleum hydrocarbons. These laws generally regulate the generation, 
storage, treatment, transportation and disposal of nonhazardous and hazardous waste and may impose strict joint and several 
liability for the investigation and remediation of affected areas where hazardous substances may have been released or 
disposed. For instance, the Comprehensive Environmental Response, Compensation, and Liability Act, or CERCLA, and 
comparable state laws impose liability, without regard to fault or the legality of the original conduct, on certain classes of 
persons that contributed to the release or threatened release of a hazardous substance into the environment. We may handle 
hazardous substances within the meaning of CERCLA, or analogous state laws, in the course of our ordinary operations and, as 
a result, may be jointly and severally liable under CERCLA for all or part of the costs required to clean up sites at which these 
hazardous substances have been released or threatened to be released into the environment.

We also generate wastes that are subject to the Resource Conservation and Recovery Act, or RCRA, and comparable state 

laws. RCRA regulates both nonhazardous and hazardous solid wastes, but it imposes strict requirements on the generation, 
storage, treatment, transportation and disposal of hazardous wastes. It is possible that wastes resulting from our operations that 
are currently treated as non-hazardous wastes could be designated as "hazardous wastes" in the future, subjecting us to more 
rigorous and costly management and disposal requirements. It is also possible that federal or state regulatory agencies will 
adopt stricter management or disposal standards for non-hazardous wastes, including natural gas wastes. Any such changes in 
the laws and regulations could have a material adverse effect on our business, financial position, results of operations and 
prospects or otherwise impose limits or restrictions on our operations or those of our customers.

In some cases, we own or lease properties where hydrocarbons are being or have been handled for many years. 

Hydrocarbons or other wastes may have been disposed of or released on or under the properties owned or leased by us or on or 
under the locations where these hydrocarbons and wastes have been transported for treatment or disposal. We could also have 
liability for releases or disposal on properties owned or leased by others. These properties and the wastes disposed thereon may 
be subject to CERCLA, RCRA and analogous state laws. Under these laws, we could be required to remove or remediate 
previously disposed wastes (including wastes disposed of or released by prior owners and operators), to clean up contaminated 
property (including contaminated groundwater) or to perform remedial operations to prevent future contamination.

Our produced water disposal operations require us to comply with the Class II well standards under the federal SDWA.
The SDWA imposes requirements on owners and operators of Class II wells through the EPA's Underground Injection Control 
program, including construction, operating, monitoring and testing, reporting and closure requirements. Our disposal wells are 
also subject to comparable state laws and regulations. Compliance with current and future laws and regulations regarding our 
produced water disposal wells may impose substantial costs and restrictions on our produced water disposal operations, as well 
as adversely affect demand for our produced water disposal services. State and federal regulatory agencies recently have 
focused on a possible connection between the operation of produced water injection wells used for oil and gas waste disposal 
and seismic activity and tremors. When caused by human activity, such events are called induced seismicity. In some instances, 
operators of produced water injection wells in the vicinity of minor seismic events have been ordered to reduce produced water 
injection volumes or suspend operations. Regulatory agencies are continuing to study possible linkage between produced water 
injection activity and induced seismicity. These developments could result in additional regulation of produced water injection 
wells, such regulations could impose additional costs and restrictions on our produced water disposal operations.

Federal and State Waters

The Federal Water Pollution Control Act, also known as the Clean Water Act, or the CWA, and comparable state laws 
impose restrictions and strict controls regarding the discharge of pollutants, including petroleum products, into state waters or 
waters of the United States. The EPA and the U.S. Army Corps of Engineers recently adopted a rule to clarify the meaning of 
the term "waters of the United States" with respect to federal jurisdiction; that rule is currently stayed nationwide. Many 
interested parties believe that the rule expands federal jurisdiction under the CWA. Regulations promulgated pursuant to the 
CWA and analogous state laws require that entities that discharge into federal and/or state waters obtain National Pollutant 
Discharge Elimination System, or NPDES, permits and/or state permits authorizing these discharges. The CWA and analogous 
state laws assess administrative, civil and criminal penalties for discharges of unauthorized pollutants into the water and impose 
16

substantial liability for the costs of removing spills from such waters. In addition, the CWA and analogous state laws require 
that individual permits or coverage under general permits be obtained by covered facilities for discharges of storm water runoff.
Some states also maintain groundwater protection programs that require permits for discharges or operations that may impact 
groundwater. We believe that we are in substantial compliance with the CWA permitting requirements as well as the conditions 
imposed thereunder and that continued compliance with such existing permit conditions will not have a material effect on our 
results of operations. 

The primary federal law related to oil spill liability is the Oil Pollution Act, or OPA, which amends and augments oil spill 
provisions of the CWA and imposes certain duties and liabilities on certain "responsible parties" related to the prevention of oil 
spills and damages resulting from such spills in or threatening United States waters or adjoining shorelines. Spill prevention, 
control and countermeasure requirements of federal laws and analogous state laws require us to maintain spill prevention 
control and countermeasure plans. These laws also require appropriate containment berms and similar structures to help prevent 
the contamination of regulated waters in the event of a hydrocarbon tank spill, rupture or leak. Regulations promulgated 
pursuant to OPA further require certain facilities to maintain oil spill prevention and oil spill contingency plans. A liable 
"responsible party" includes the owner or operator of a facility, vessel or pipeline that is a source of an oil discharge or that 
poses the substantial threat of discharge, or in the case of offshore facilities, the lessee or permittee of the area in which a 
discharging facility is located. OPA assigns joint and several liability, without regard to fault, to each liable party for oil 
removal costs and a variety of public and private damages. Although defenses exist to the liability imposed by OPA, they are 
limited. In the event of an oil discharge or substantial threat of discharge, we may be liable for costs and damages.

Endangered Species

The Endangered Species Act, or ESA, restricts activities that may affect endangered or threatened species or their habitats. 

While some of our operations may be located in areas that are designated as habitats for endangered or threatened species, we 
believe that we are in substantial compliance with the ESA. However, the designation of previously unlisted endangered or 
threatened species could cause us to incur additional costs or become subject to operating restrictions or bans or limit future 
development in the affected areas.

National Environmental Policy Act

The National Environmental Policy Act, or NEPA, establishes a national environmental policy and goals for the protection, 
maintenance and enhancement of the environment and provides a process for implementing these goals within federal agencies. 
A major federal agency action having the potential to significantly impact the environment requires review under NEPA and, as 
a result, many activities requiring FERC or other federal approval must undergo a NEPA review. A NEPA review can create 
delays and increased costs that could materially adversely affect our operations.

Employee Safety

We are subject to the requirements of OSHA and comparable state statutes that regulate the protection of the health and 

safety of workers. In addition, the OSHA hazard communication standard requires that information be maintained about 
hazardous materials used or produced in operations and that this information be provided to employees, state and local 
government authorities and citizens. We believe that our operations are in substantial compliance with OSHA requirements, 
including general industry standards, record keeping requirements, and monitoring of occupational exposure to regulated 
substances.

Seasonality

Weather generally impacts natural gas demand for power generation, heating purposes and other natural gas usages, which 

in turn influences the value of transportation and storage. Price volatility also affects gas prices, which in turn influences 
drilling and production. Peak demand for natural gas typically occurs during the winter months, caused by heating demand. 
Nevertheless, because a high percentage of our natural gas transportation and storage and crude oil transportation revenues are 
derived from firm capacity reservation fees under long-term firm fee contracts, our revenues attributable to those segments are 
not generally seasonal in nature. We experience some seasonality in our processing segment, as volumes at our processing 
facilities are slightly higher in the summer months. We also experience some seasonality in our maintenance, repair, overhaul, 
integrity, and other projects, as warm weather months are most conducive to efficient execution of these activities.

Title to Properties and Rights-of-Way

Our real property generally falls into two categories: (i) parcels that we own in fee and (ii) parcels in which our interest 

derives from leases, easements, rights-of-way, permits, surface use agreements, or licenses from landowners or governmental 
authorities, permitting the use of such land for our operations. Portions of the land on which our pipelines and facilities are 
located are owned by us in fee title, and we believe that we have satisfactory title to these lands. The remainder of the land on 
which our pipelines and facilities are located are held by us pursuant primarily to leases, easements, rights-of-way, permits, 
surface use agreements or licenses between us, as grantee, and a third party, as grantor. We believe that we have satisfactory 

17

title to all of our material parcels that we own in fee and the material parcels in which our interest derives from leases, 
easements, rights-of-way, permits and licenses, and we have no knowledge of any challenge that we expect will impact our title 
to such assets or their underlying fee title in any material respect.

Some of the leases, easements, rights-of-way, permits and licenses we acquire, including those we acquired in the IPO, 

require the consent of the grantor for the assignment/conveyance of such rights, which in certain instances is a governmental 
entity. The transferor, such as Tallgrass Development or its affiliates, may continue to hold record title to portions of certain 
assets until we make the appropriate filings in the jurisdictions in which such assets are located and obtain any consents and 
approvals that are not obtained prior to transfer. Such consents and approvals would include those required by federal and state 
agencies or political subdivisions. In some cases, Tallgrass Development may, where required consents or approvals have not 
been obtained, temporarily hold record title to property as nominee for our benefit and in other cases may, on the basis of 
expense and difficulty associated with the conveyance of title, cause its affiliates to retain title, as nominee for our benefit, until 
a future date. We anticipate that there will be no material change in the tax treatment of our common units resulting from 
Tallgrass Development holding the title to any part of such assets subject to future conveyance or as our nominee.

Insurance

We generally share insurance coverage with Tallgrass Development and TEGP, for which we reimburse Tallgrass
Development and its affiliates for our share of the cost pursuant to the terms of the TEP Omnibus Agreement. This shared 
insurance program includes general and excess liability insurance, auto liability insurance, workers' compensation insurance, 
pollution, business interruption and property and director and officer liability insurance. All insurance coverage is in amounts 
which management believes are reasonable and appropriate.

Employees

We do not have any employees. We are managed and operated by the board of directors and executive officers of our 
general partner. All of our employees are employed by an affiliate of Tallgrass Energy Holdings and devote the portion of their 
time to our business and affairs that is reasonably required to manage and conduct our operations. Under the terms of the TEP
Omnibus Agreement and our partnership agreement, we reimburse Tallgrass Development and our general partner, respectively,
for the provision of various general and administrative services for our benefit and for direct expenses incurred by Tallgrass
Development or our general partner on our behalf, including services performed and expenses incurred by our executive 
management personnel in connection with our business and affairs.

Available Information

We make certain filings with the SEC, including our Annual Report on Form 10-K, quarterly reports on Form 10-Q, 
current reports on Form 8-K, and all amendments and exhibits to those reports. We make such filings available free of charge
through our website, www.tallgrassenergy.com, as soon as reasonably practicable after they are filed with the SEC. The filings 
are also available through the SEC's website, www.sec.gov, at the SEC's Public Reference Room at 100 F Street, N.E., 
Washington, D.C. 20549 or by calling 1-800-SEC-0330. Our press releases and recent presentations are also available on our 
website.

Item 1A. Risk Factors

Limited partner interests are inherently different from shares of capital stock of a corporation, although many of the 
business risks to which we are subject are similar to those that would be faced by a corporation engaged in similar businesses. 
If any of the following risks were to occur, our business, financial condition or results of operations could be materially 
adversely affected. In that case, we might not be able to pay quarterly distributions on our common units at the current 
distribution level, or pay any distribution at all, and the trading price of our common units could decline.

Risks Related to Our Business

We may not have sufficient cash from operations following the establishment of cash reserves and payment of fees and 

expenses, including cost reimbursements to our general partner and its affiliates, to enable us to pay the quarterly 
distribution at the current distribution level, or at all, to holders of our common units.

We may not have sufficient available cash from operating surplus each quarter to enable us to pay the quarterly distribution 

at the current distribution level, at the minimum quarterly distribution level, or at all. The amount of cash we can distribute on 
our units principally depends upon the amount of cash we generate from our operations, which will fluctuate from quarter to 
quarter based on, among other things:

•

•

the level of firm services we provide to customers pursuant to firm fee contracts and the volume of customer products 
we transport, store, process, gather, treat and dispose using our assets;

our ability to renew or replace expiring long-term firm fee contracts with other long-term firm fee contracts;

18

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

the creditworthiness of our customers, particularly customers who are subject to firm fee contracts;

our ability to complete and integrate acquisitions from Tallgrass Development or from third parties; 

the level of production of crude oil, natural gas and other hydrocarbons and the resultant market prices of natural gas, 
NGLs, crude oil and other hydrocarbons;

the actual and anticipated future prices, and the volatility thereof, of natural gas, crude oil and other commodities;

changes in the fees we charge for our services, including firm services and interruptible services;

our ability to identify, develop, and complete internal growth projects or expansion capital expenditures on favorable 
terms to improve optimization of our current assets;

regional, domestic and foreign supply and perceptions of supply of natural gas, crude oil and other hydrocarbons; 

the level of demand and perceptions of demand in end-user markets we directly or indirectly serve; 

applicable laws and regulations affecting our and our customers' business, including the market for natural gas, crude 
oil, other hydrocarbons and water, the rates we can charge on our assets, how we contract for services, our existing 
contracts, our operating costs or our operating flexibility;

prevailing economic conditions;

the effect of seasonal variations in temperature and climate on the amount of customer products we are able to 
transport, store, process, gather, treat and dispose using our assets;

the realized pricing impacts on revenues and expenses that are directly related to commodity prices;

the level of competition from other midstream energy companies in our geographic markets;

the level of our operating and maintenance costs;

damage to our assets and surrounding properties caused by earthquakes, floods, fires, severe weather, explosions and 
other natural disasters or acts of terrorism;

outages in our assets;

the relationship between natural gas and NGL prices and resulting effect on processing margins; and

leaks or accidental releases of hazardous materials into the environment, whether as a result of human error or 
otherwise.

In addition, the actual amount of cash we will have available for distribution will depend on other factors, including:

•

•

•

•

•

•

•

•

•

our ability to borrow funds and access capital markets;

the level, timing and characterization of capital expenditures we make;

the level of our general and administrative expenses, including reimbursements to our general partner and its affiliates,
including Tallgrass Development, for services provided to us;

the cost of pursuing and completing acquisitions, if any;

our debt service requirements and other liabilities;

fluctuations in our working capital needs;

restrictions contained in our debt agreements;

the amount of cash reserves established by our general partner; and

other business risks affecting our cash levels.

19

If we are not able to renew or replace expiring customer contracts at favorable rates or on a long-term basis, our 
financial condition, results of operations, cash flows and ability to make cash distributions to our unitholders will be 
adversely affected.

A substantial majority of our contracts for transporting, storing, and processing our customers' products on our systems are 
long-term firm fee contracts with terms of various durations. For the year ended December 31, 2016, approximately 89% of our 
crude oil transportation revenues were generated under firm fee transportation contracts and approximately 92% of our natural 
gas transportation and storage revenues were generated under firm fee transportation and storage contracts. As of December 31,
2016, the weighted average remaining life of our oil transportation contracts was approximately three years, the weighted 
average remaining life of our long-term natural gas transportation contracts and natural gas storage contracts at TIGT and 
Trailblazer was approximately three years and five years, respectively, and the weighted average remaining life of our natural 
gas processing contracts was approximately two years. In addition, a majority of Rockies Express' west-to-east pipeline 
capacity is subject to long-term firm fee contracts that expire in 2019 and a significant amount of Rockies Express' revenue in 
2016 was derived under these contracts. 

We may be unable to maintain the long-term nature and economic structure of our current contract portfolio over time. 

Depending on prevailing market conditions at the time of a contract renewal, our natural gas transportation, storage and 
processing customers with long-term fee-based contracts may desire to enter into contracts with reduced fees, and may be 
unwilling to enter into long-term contracts at all. In addition, most of the long-term contracts for the Pony Express Pipeline 
expire in 2019 and those customers may unilaterally decide whether to renew such contract. If those customers do not renew 
their contract, under current FERC policy, Pony Express is generally prohibited from entering into new long-term contracts that 
grant contract shippers priorities in prorationing under the ICA unless such contract relates to an increase in the capacity of the 
Pony Express Pipeline. 

Our ability to renew or replace our expiring contracts on terms similar to, or more attractive than, those of our existing 

contracts is uncertain and depends on a number of factors beyond our control, including:

•

•

•

•

•

the level of existing and new competition to provide competing services to our markets;

the macroeconomic factors affecting crude oil and natural gas economics for our current and potential customers;

the balance of supply and demand for natural gas, crude oil and other hydrocarbons, on a short-term, seasonal and 
long-term basis, in the markets we serve;

the extent to which the current and potential customers in our markets are willing to provide firm fee commitments on 
a long-term basis; and

the effects of federal, state or local laws or regulations on the contracting practices of our customers.

In the current commodity environment, which included significant price reduction and volatility in crude oil, natural gas 

and other hydrocarbons from the second half of 2014 through the first half of 2016, we expect customers will generally 
continue to be less likely to enter into long-term firm fee contracts until prices recover and stability returns to the commodity 
markets. Customers who do enter into long-term contracts may only be willing to provide acreage dedications to our assets 
rather than firm fee commitments. Acreage dedications typically do not require our customers to pay us unless they utilize our 
assets, and they may also be subject to challenge in bankruptcy proceedings. 

To the extent we are unable to renew or replace our existing contracts on terms that are favorable to us or successfully 
manage the long-term nature and economic structure of our contract profile over time, our revenues and cash flows could 
decline and our ability to make distributions to our unitholders could be materially and adversely affected.

We are exposed to the creditworthiness and performance of our customers, suppliers and contract counterparties, and 

any material nonpayment or nonperformance by one or more of these parties could adversely affect our financial condition, 
cash flows, and operating results.

Although we attempt to assess the creditworthiness of our customers, suppliers and contract counterparties, there can be no 

assurance that our assessments will be accurate or that there will not be a rapid or unanticipated deterioration in their 
creditworthiness, which may have an adverse impact on our business, results of operations, financial condition and ability to 
make cash distributions to our unitholders. Our long-term firm fee contracts obligate our customers to pay demand charges
regardless of whether they utilize our assets, except for certain circumstances outlined in applicable customer agreements. As a 
result, during the term of our long-term firm fee contracts, and absent an event of force majeure, our revenues will generally 
depend on our customers' financial condition and their ability to pay rather than upon the extent to which our customers 
actually utilize our assets. The decline and volatility in natural gas and crude oil prices during the second half of 2014 through 
the first half of 2016 negatively impacted the financial condition of our customers and future declines, lower prices, or volatility 
could impact their ability to meet their financial obligations to us. Further, our contract counterparties may not perform or 
adhere to our existing or future contractual arrangements. To the extent one or more of our contract counterparties is in 

20

financial distress or commences bankruptcy proceedings, contracts with these counterparties may be subject to renegotiation or 
rejection under applicable provisions of the United States Bankruptcy Code. Any material nonpayment or nonperformance by 
our contract counterparties due to inability or unwillingness to perform or adhere to contractual arrangements could have a 
material adverse impact on our business, results of operations, financial condition and ability to make cash distributions to our 
unitholders.

For example, in 2016, Ultra Resources, Inc., or Ultra, defaulted on its firm transportation service agreement with Rockies 

Express for approximately 0.2 Bcf/d through November 11, 2019, and as a result, Rockies Express filed a lawsuit seeking 
approximately $303 million in damages and other relief. Approximately 13% of Rockies Express' revenue in 2015 was derived 
from the Ultra contract. In April 2016 Ultra filed for bankruptcy protection. On January 12, 2017, Rockies Express and Ultra 
agreed to settle Rockies Express’s claim against Ultra's bankruptcy estate. The settlement includes Ultra's agreement to pay 
Rockies Express $150 million in cash no later than October 30, 2017 and enter into a new, seven-year firm transportation 
agreement with Rockies Express commencing December 1, 2019, for west-to-east service of 0.2 Bcf/d at a rate of 
approximately $0.37, or approximately $26.8 million annually. The settlement is part of Ultra's Chapter 11 reorganization plan, 
and therefore subject to the approval of the U.S. Bankruptcy Court. There is no assurance that Ultra's Chapter 11 reorganization
plan will be approved or that Ultra will meet the terms and conditions for such plan to become effective.

In addition, Triad Hunter, LLC, or Triad, sought bankruptcy relief in December 2015. At the time Triad commenced the 

bankruptcy proceedings, Triad and Rockies Express were parties to a precedent agreement that provided Triad with an 
approximate 0.1 Bcf/d of firm capacity in connection with the Rockies Express Zone 3 Capacity Enhancement Project. In order 
to settle its claim, Rockies Express agreed to amend certain material terms of the precedent agreement, including reducing 
Triad's firm capacity under the precedent agreement to an approximate 0.05 Bcf/d. 

Although the Triad and Ultra claims were ultimately settled, and on terms TEP and Rockies Express view as favorable, the 

settlements will not deliver the same benefits as the underlying contract at issue in each circumstance.  

The procedures and policies we use to manage our exposure to credit risk, such as credit analysis, credit monitoring and, in 
some cases, requiring credit support, cannot fully eliminate counterparty credit risks. In accordance with FERC regulations and 
our own internal credit policies, counterparties with investment grade credit ratings are deemed able to meet their financial 
obligations to us without requiring credit support in the form of a letter of credit or prepayment. With the decline and volatility 
in natural gas and crude oil prices over the last two years and the corresponding deterioration of the financial condition of some 
of our customers, the percent of our revenue from customers with investment grade credit ratings fell to slightly under 45%
during the year ended December 31, 2016. Although we ask for credit support from customers without investment grade credit 
ratings, some customers may be unwilling or unable to provide it due to liquidity constraints. To the extent our procedures and 
policies prove to be inadequate or we are unable to obtain credit support, our financial position and results of operations may be 
negatively impacted.

Some of our counterparties may be highly leveraged or have limited financial resources and are subject to their own 
operating and regulatory risks. Even if our credit review and analysis mechanisms work properly, we may experience financial 
losses in our dealings with such parties. As seen with the decline and volatility in crude oil prices from the second half of 2014 
through the first half of 2016, prices for crude oil and natural gas are subject to large fluctuations in response to changes in 
supply and demand, market uncertainty and a variety of other factors that are beyond our control. Such volatility in commodity 
prices might have an impact on many of our counterparties and their ability to borrow and obtain additional capital on attractive 
terms, which, in turn, could have a negative impact on their ability to meet their obligations to us and may also increase the 
magnitude of these obligations. 

Any material nonpayment or nonperformance by our counterparties could require us to pursue substitute counterparties for 
the affected operations, reduce operations or provide alternative services. There can be no assurance that any such efforts would 
be successful or would provide similar financial and operational results.

We depend on certain key customers for a significant portion of our revenues and are exposed to credit risks of these
customers. The loss of or material nonpayment or nonperformance by any of these key customers could adversely affect our
cash flow and results of operations.

We rely on certain key customers for a portion of revenues. For example, for the year ended December 31, 2016, Continental
Resources and Shell accounted for approximately 16% and 13% of our revenues on a consolidated basis, respectively. In addition,
for the year ended December 31, 2016, approximately 60% of our consolidated revenues were represented by the top ten customers
on our Pony Express System. We own a 25% membership interest in Rockies Express, which is not consolidated for financial
reporting purposes. Approximately 23%, 12%, 10%, and 10%, respectively, of Rockies Express' total revenues as of December
31, 2016 were represented by Rockies Express' four largest non-affiliated shippers.

21

We may be unable to negotiate extensions or replacements of contracts with key customers on favorable terms. For 

additional detail, see "—If we are not able to renew or replace expiring customer contracts at favorable rates or on a long-term 
basis, our financial condition, results of operations, cash flows and ability to make cash distributions to our unitholders will be 
adversely affected."

 In addition, some of these key customers may experience financial problems that could have a significant effect on their 
creditworthiness. For example, Rockies Express terminated its contract with its third largest non-affiliated shipper by total 2015 
revenue, Ultra, in March 2016. For more detail regarding Ultra, see "—We are exposed to the creditworthiness and performance 
of our customers, suppliers and contract counterparties, and any material nonpayment or nonperformance by one or more of 
these parties could adversely affect our financial condition, cash flows, and operating results."

Severe financial problems encountered by our customers could limit our ability to collect amounts owed to us, or to 
enforce performance of obligations under contractual arrangements. To the extent one or more of our key customers is in 
financial distress or commences bankruptcy proceedings, contracts with these customers may be subject to renegotiation or 
rejection under applicable provisions of the United States Bankruptcy Code. Additionally, many of our customers finance their 
activities through cash flow from operations, the incurrence of indebtedness or the issuance of equity. The combination of 
reduction of cash flow resulting from declines in commodity prices, a reduction in borrowing bases under credit facilities and 
the lack of availability of debt or equity financing may result in a significant reduction of our customers' liquidity and limit 
their ability to make payments or perform on their obligations to us. Furthermore, some of our customers may be highly 
leveraged and subject to their own operating and regulatory risks, which increases the risk that they may default on their 
obligations to us. The loss of all or even a portion of the contracted volumes of these key customers, as a result of competition, 
creditworthiness or otherwise, could have a material adverse effect on our business, cash flows, ability to make distributions to 
our unitholders, the price of our units, our results of operations and ability to conduct our business.

If we are unable to make acquisitions on economically acceptable terms from Tallgrass Development or third parties, 
our future growth will be limited, and the acquisitions we do make may reduce, rather than increase, our cash generated 
from operations on a per unit basis.

Our ability to grow depends, in part, on our ability to make acquisitions that increase our cash generated from operations 

on a per unit basis. 

The acquisition component of our strategy is based, in part, on our expectation of ongoing divestitures of midstream energy

assets by industry participants, including Tallgrass Development. Many factors could impair our access to future midstream 
assets, including a change in control of Tallgrass Development. A material decrease in divestitures of midstream energy assets 
from Tallgrass Development or otherwise would limit our opportunities for future acquisitions and could have a material 
adverse effect on our business, results of operations, financial condition and ability to make quarterly cash distributions to our 
unitholders.

Our future growth and ability to increase distributions will be limited if we are unable to make accretive acquisitions from 
Tallgrass Development or third parties because, among other reasons, (i) Tallgrass Development elects not to sell or contribute 
additional assets to us or to offer acquisition opportunities to us, (ii) we are unable to identify attractive third-party acquisition 
opportunities, (iii) we are unable to negotiate acceptable purchase contracts with Tallgrass Development or third parties, (iv) we 
are unable to obtain financing for these acquisitions on economically acceptable terms, (v) we are outbid by competitors or (vi) 
we are unable to obtain necessary governmental or third-party consents. Furthermore, even if we do make acquisitions that we 
believe will be accretive, these acquisitions may nevertheless result in a decrease in the cash generated from operations on a per 
unit basis. For example, we acquired a 25% membership interest in Rockies Express in May 2016, and if certain risks or 
unanticipated liabilities were to arise, the desired benefits of the acquisition may not be fully realized and our future financial 
performance and results of operations could be negatively impacted.

Any acquisition involves potential risks, including, among other things:

• mistaken assumptions about volumes, revenue and costs, including synergies and potential growth;

•

•

•

•

•

•

an inability to maintain or secure adequate customer commitments to use the acquired systems or facilities;

an inability to successfully integrate the assets or businesses we acquire;

the assumption of unknown liabilities for which we are not indemnified or for which our indemnity is inadequate;

the diversion of management's and employees' attention from other business concerns;

unforeseen difficulties operating in new geographic areas or business lines; and

a decrease in liquidity and increased leverage as a result of using significant amounts of available cash or debt to 
finance an acquisition.

22

If any acquisition eventually proves not to be accretive to our distributable cash flow per unit, it could have a material 
adverse effect on our business, results of operations, financial condition and ability to make quarterly cash distributions to our 
unitholders.

If we are unable to obtain needed capital or financing on satisfactory terms to fund expansions of our asset base, our 

ability to make quarterly cash distributions may be diminished or our financial leverage could increase.

In order to expand our asset base through acquisitions or capital projects, we may need to make expansion capital 
expenditures. If we do not make sufficient or effective expansion capital expenditures, we will be unable to expand our 
business operations and may be unable to maintain or raise the level of our quarterly cash distributions. We could be required to 
use cash from our operations or incur borrowings or sell additional common units or other limited partner interests in order to 
fund our expansion capital expenditures. Using cash from operations will reduce cash available for distribution to our common 
unitholders. Our ability to obtain bank financing or to access the capital markets for future equity or debt offerings may be 
limited by our financial condition at the time of any such financing or offering as well as the covenants in our debt agreements, 
general economic conditions and contingencies and uncertainties that are beyond our control. Even if we are successful in 
obtaining funds for expansion capital expenditures through equity or debt financings, the terms thereof could limit our ability to 
pay distributions to our common unitholders. In addition, incurring additional debt may significantly increase our interest 
expense and financial leverage, and issuing additional limited partner interests may result in significant common unitholder 
dilution and increase the aggregate amount of cash required to maintain the then-current distribution rate, which could 
materially decrease our ability to pay distributions at the then-current distribution rate. We do not currently have any 
commitment with our general partner or other affiliates, including Tallgrass Development, for them to provide any direct or 
indirect financial assistance to us.

The Throughput and Deficiency Agreements for the Pony Express System and some of our service agreements with 
respect to our water business services contain provisions that can reduce the cash flow stability that the agreements were 
designed to achieve.

The Throughput and Deficiency Agreements, or TDAs, for the Pony Express System and some of our service agreements 

with respect to our water services business are firm fee contracts with minimum volume commitments that are designed to 
generate stable cash flows and minimize direct commodity price risk. Under these minimum volume commitments, our 
customers agree to ship a minimum volume of crude oil or to have a minimum volume of water serviced, as the case may be, 
over certain periods during the term of the applicable agreement. 

If a customer's actual throughput volumes or volumes serviced are less than its minimum volume commitment for the 
applicable period, it must make a deficiency payment at the end of the applicable period based upon the difference between the 
minimum volume commitment and the actual amounts serviced. A customer may apply any deficiency payments it makes as a 
credit against payment for volumes transported or serviced by us in excess of its minimum volume commitment in future 
periods. Upon termination of the Pony Express TDAs, customers may continue to use any remaining deficiency credits against 
any volumes serviced by us for a period of six months following termination, even though such customers may no longer have 
a minimum volume commitment. 

To the extent that a customer's actual throughput volumes or volumes serviced are above its minimum volume commitment 

for the applicable period, the customer may use the excess volumes to credit against future deficiency payments in subsequent 
periods. As of December 31, 2016, Pony Express had a cumulative net deficiency balance of $60.6 million and a cumulative 
shipper incremental balance of $24.4 million.

Some or all of these provisions can apply in combination with one another. As a result, in the future we may not receive 
any cash payments for volumes shipped or serviced by us, and we may not receive deficiency payments as a result of excess 
volumes shipped in prior periods. This would result in reduced revenue and cash flows to us.

We may not be able to compete effectively in our midstream services activities and our business is subject to the risk of a 

capacity overbuild of midstream energy infrastructure in the areas where we operate.

We face competition in all aspects of our business and may not be able to compete effectively against our competitors. In 

general, competition comes from a wide variety of players in a wide variety of contexts, including new entrants and existing 
players and in connection with day-to-day business, expansion capital projects, acquisitions and joint venture activities. Some 
of our competitors have capital resources greater than ours and control greater supplies of crude oil, natural gas or NGLs.

23

Our ability to renew or replace our existing contracts at rates sufficient to maintain current revenues and current cash flows 

could be adversely affected by the activities of our competitors. Some of our competitors have assets in closer proximity to 
certain hydrocarbon supplies and have available idle capacity in existing assets that may require no or minimal capital 
investments for use. For example, several pipelines access many of the same basins as our assets and provide transport to 
customers in the Rocky Mountain, Appalachian Mountain and Midwest regions of the United States, such as the Saddlehorn-
Grand Mesa Pipeline and White Cliffs Pipeline that compete with the Pony Express Pipeline. Pony Express also competes with 
rail facilities, which can provide more delivery optionality to crude oil producers and marketers looking to capitalize on basis 
differentials between two primary crude oil benchmarks (West Texas Intermediate Crude and Brent Crude). Furthermore, 
Tallgrass Development and its affiliates are not limited in their ability to compete with us. 

Our competitors may expand or construct new midstream services assets that would create additional competition for the 

services we provide to our customers, or our customers may develop their own facilities in lieu of using ours. A significant 
driver of competition in some of the markets where we operate (including, for example, the Rocky Mountain and Appalachian
Mountain regions) has been the rapid development of new midstream energy infrastructure capacity in recent years. As a result, 
we are exposed to the risk that the areas in which we operate become overbuilt, resulting in an excess of midstream energy
infrastructure capacity. If we experience a significant capacity overbuild in one or more of the areas where we operate, it could 
have a significant adverse impact on our financial position, cash flows and ability to pay or increase distributions to our 
unitholders. For example, our competitors in these areas could substantially decrease the prices at which they offer their 
services, and we may be unable to compete effectively. This could materially impair our cash flows and ability to make 
distributions to our unitholders.

Further, natural gas as a fuel, and fuels derived from crude oil, compete with other forms of energy available to users, 
including electricity, coal, other liquid fuels and alternative energy. Increased demand for such forms of energy at the expense 
of natural gas or fuels derived from crude oil could lead to a reduction in demand for our services.

All of these competitive pressures could make it more difficult for us to renew our existing long-term firm fee contracts 
when they expire or to attract new customers as we seek to expand our business, which could have a material adverse effect on 
our business, financial condition, results of operations and prospects. In addition, competition could intensify the negative 
impact of factors that decrease demand for natural gas and crude oil in the markets we serve, such as adverse economic 
conditions, weather, higher fuel costs and taxes or other governmental or regulatory actions decreasing demand.

Constructing new assets subjects us to risks of project delays, cost overruns and lower-than-anticipated volumes of 

natural gas or crude oil once a project is completed. Our operating cash flows from our capital projects may not be 
immediate or meet our expectations.

One of the ways we may grow our business is by constructing additions or modifications to our existing facilities. We also 

may construct new facilities, either near our existing operations or in new areas. Construction projects require significant 
amounts of capital and involve numerous regulatory, environmental, political, legal and operational uncertainties, many of 
which are beyond our control. We may be unable to complete announced construction projects on schedule, at the budgeted 
cost, or at all, which could have a material adverse effect on our business and results of operations. For example, on June 17, 
2014, Michels Corporation, or Michels, filed a complaint and request for relief against Rockies Express as a result of work 
performed by Michels to construct the Seneca Lateral Pipeline in Ohio. Michels sought unspecified damages from Rockies 
Express and asserted claims of breach of contract, negligent misrepresentation, unjust enrichment and quantum meruit, and also 
filed notices of Mechanic's Liens in Monroe and Noble Counties, asserting $24.2 million as the amount due. On February 2, 
2017, Rockies Express and Michels entered into a binding settlement agreement to resolve the claims brought by Michels in 
exchange for a $10 million cash payment by Rockies Express.

These projects also involve numerous economic uncertainties and the cash flow generated from these projects may not 
meet expectations or project estimates. Moreover, we may not receive any material increase in operating cash flow from a 
project for some time or at all. For instance, with respect to the Rockies Express Zone 3 Capacity Enhancement Project, 
substantially all of the construction expenditures have been incurred during 2015 and 2016, yet Rockies Express will only 
receive increases in cash flow from the project now that it is completed and was placed in-service in January 2017. 

The project specifications and expectations regarding project cost, timing, asset performance, investment returns and other 

matters usually rely in part on the expertise of third parties such as engineers, technical experts and construction contractors. 
These estimates may prove to be inaccurate because of numerous operational, technological, economic and other uncertainties. 
We also rely in part on estimates from producers regarding the timing and volume of anticipated natural gas and crude oil 
production. Production estimates are subject to numerous uncertainties, nearly all of which are beyond our control. These
estimates may prove to be inaccurate, and new facilities may not attract sufficient volumes to achieve our expected cash flow 
and investment return.

24

We have certain long-term fixed priced natural gas and crude oil transportation contracts that cannot be adjusted even 

if our costs increase. As a result, our costs could exceed our revenues.

As of December 31, 2016, approximately 40% of our contracted natural gas transportation firm capacity was provided 

under long-term, fixed price "negotiated or discount rate" contracts that are not subject to adjustment, even if our cost to 
perform such services exceeds the revenues received from such contracts, and, as a result, our costs could exceed our revenues 
received under such contracts. It is possible that costs to perform services under our "negotiated or discount rate" contracts will 
exceed the negotiated or discounted rates. It is also possible with respect to discounted rates that if our filed "recourse rates" 
should ever be reduced below applicable discounted rates, we would only be allowed by the FERC to charge the lower recourse 
rates, since FERC policy does not allow discount rates to be charged to the extent that they exceed applicable recourse rates. If 
these events were to occur, it could decrease the cash flow realized by our assets and, therefore, the cash we have available for 
distributions to our unitholders. 

Under FERC policy, a regulated service provider and a customer may mutually agree to sign a contract for service at a 
"negotiated rate," which is generally fixed between the natural gas pipeline and the shipper for the contract term and does not 
necessarily vary with changes in the level of cost-based "recourse rates," provided that the affected customer is willing to agree 
to such rates and that the FERC has accepted the negotiated rate agreement. These "negotiated or discount rate" contracts are 
not generally subject to adjustment for increased costs which could be caused by inflation or other factors relating to the 
specific facilities being used to perform the services. Any shortfall of revenue, representing the difference between "recourse 
rates" (if higher) and negotiated or discounted rates, under current FERC policy, may be recoverable from other shippers in 
certain circumstances. For example, the FERC may recognize this shortfall in the determination of prospective rates in a future 
rate case. However, if the FERC were to disallow the recovery of such costs from other customers, it could decrease the cash 
flow realized by our assets and, therefore, the cash we have available for distributions to our unitholders.

Rates under Pony Express' TDAs are typically subject to change only per contract terms and conditions, including Pony 

Express' right to file changes to contract rates to reflect annual index percentage adjustments published by the FERC. We
generally cannot file for rate increases with respect to committed shippers who have signed TDAs, other than to reflect annual 
index adjustments or to recover compliance costs imposed by governmental actions. 

A significant amount of the revenue currently generated by the Pony Express System, and a significant amount of 
Rockies Express' revenue, are from contracts that contain most favored nations rights, limiting flexibility to offer certain 
capacity to new shippers.

Approximately 90% of the Pony Express System's current available capacity is provided to committed shippers under long-

term TDAs. Some of the TDAs contain most favored nations rights, or MFNs, which could result in lower rates being charged
to certain committed shippers to ensure that the rates such shippers are paying are no greater than ninety to one hundred percent 
of the rates being charged to other similarly situated shippers for similar service at similar volumes and terms. Triggering the 
MFNs on the TDAs could lead to a reduction in revenue generated by Pony Express, which could have a material adverse effect
on our revenues, cash flow, results of operations and our ability to make distributions to our unitholders.

Rockies Express' foundation and anchor shippers for west-to-east service hold certain MFNs granting them a right to a rate 
reduction in certain instances where Rockies Express provides service to another shipper at a rate lower than the foundation or 
anchor shipper rate for a term of one year or greater or, in the case of the foundation shipper, from certain specified receipt 
locations. The MFNs effectively limit Rockies Express' flexibility in negotiating rates for some of its services with other 
shippers, because triggering the MFNs of the foundation and anchor shippers could lead to a reduction in the rates that Rockies 
Express charges, which could have a material adverse effect on Rockies Express' revenues, cash flow and results of operations, 
which in turn could impair our ability to make distributions to our unitholders. 

If third-party pipelines or other facilities interconnected to our systems become partially or fully unavailable, or if the 

volumes we transport do not meet the quality requirements of such pipelines or facilities, our revenues and our ability to 
make distributions to our unitholders could be adversely affected.

Our assets typically connect to other pipelines or facilities owned, leased and/or operated by unaffiliated third parties, such 
as the ONEOK Bakken Pipeline, L.L.C., Deeprock Development, Whiting, and others. For example, our Pony Express System 
connects to upstream joint tariff pipelines, including the Belle Fourche Pipeline owned by the True Companies (which also own 
and operate the Bridger Pipeline upstream of the Belle Fourche Pipeline) and the Double H Pipeline owned by Kinder Morgan,
which are responsible for delivering a substantial portion of the crude oil for transportation on the Pony Express System. In 
addition, part of the crude oil we transport on the Pony Express System is either stored in crude oil tanks located on, or pumped 
over to downstream pipelines that interconnect through the Cushing Terminal, which we do not operate.

25

The continuing operation of such third-party facilities and other midstream facilities is not within our control. These
pipelines, plants and other midstream facilities may become unavailable to us for any number of reasons, including because of 
testing, turnarounds, line repair, extended unscheduled maintenance, reduced operating pressure, lack of operating capacity,
regulatory requirements, curtailments of receipt or deliveries due to insufficient capacity or because of damage from weather 
events or other operational hazards. For example, the operations of the Bridger Pipeline's Poplar System were down for 
approximately five months during the first half of 2015 due to a pipeline release. Bridger declared a force majeure as a result of 
this event and temporarily lacked the capacity to make up volumes on other lines that directly or indirectly deliver crude oil into 
designated origin points on the Pony Express System or the Belle Fourche Pipeline. The largest committed shipper on the Pony 
Express System also declared a force majeure as a result of this incident. 

If the costs to us to access and transport on these third-party pipelines or any alternative pipelines significantly increase, if 

any of these pipelines or other midstream facilities become unable to receive, transport, store or process products from our 
assets, or if the volumes we transport or process do not meet the quality requirements of such pipelines or facilities, our 
revenues and our ability to make quarterly cash distributions to our unitholders could be adversely affected.

The lack of diversification of our assets and geographic locations could adversely affect our ability to make 

distributions to our common unitholders.

We rely on revenues generated from our assets, which are primarily located in the Rocky Mountain, Appalachian Mountain 
and Midwest regions of the United States. Revenues on our assets primarily depend on exploration and production activities of 
our customers located in these regions. Due to our lack of diversification in assets and geographic location, an adverse 
development in these businesses or our customers' areas of operations, including adverse developments due to catastrophic 
events, weather, regulatory action and decreases in supply or demand for hydrocarbons, could have a significantly greater 
impact on our results of operations and cash available for distribution to our common unitholders than if we maintained more 
diverse assets and locations. For example, our water business services are concentrated in a limited number of assets and 
primarily consists of our water business operations in Weld County, Colorado. Thus, the growth and profitability of our water 
business services will be especially vulnerable to conditions and fluctuations in the local Weld County economy and subject to 
changes in local government regulations and priorities.

Our operations are dependent on our rights and ability to receive or renew the required permits and other approvals 

from governmental authorities and other third parties.

Performance of our operations requires that we obtain and maintain numerous environmental and land use permits and 
other approvals authorizing our business activities. A decision by a governmental authority or other third party to deny, delay or 
restrictively condition the issuance of a new or renewed permit or other approval, or to revoke or substantially modify an 
existing permit or other approval, could have a material adverse effect on our ability to initiate or continue operations at the 
affected location or facility. Expansion of our existing operations is also predicated on securing the necessary environmental or 
land use permits and other approvals, which we may not receive in a timely manner or at all.

In order to obtain permits and renewals of permits and other approvals in the future, we may be required to prepare and 
present data to governmental authorities pertaining to the potential adverse impact that any proposed activities may have on the 
environment, individually or in the aggregate, including on public and Indian lands. Certain approval procedures may require 
preparation of archaeological surveys, endangered species studies and other studies to assess the environmental impact of new 
sites or the expansion of existing sites. Compliance with these regulatory requirements is expensive and significantly lengthens 
the time needed to develop a site or pipeline alignment. Also, obtaining or renewing required permits or other approvals is 
sometimes delayed or prevented due to community opposition and other factors beyond our control. The denial of a permit or 
other approval essential to our operations or the imposition of restrictive conditions with which it is not practicable or feasible 
to comply could impair or prevent our ability to develop or expand a property or right-of-way. Significant opposition to a 
permit or other approval by neighboring property owners, members of the public or non-governmental organizations, or other 
third parties or delay in the environmental review and permitting process also could impair or delay our ability to develop or 
expand a property or right-of-way. New legal requirements, including those related to the protection of the environment, could 
be adopted at the federal, state and local levels that could materially adversely affect our operations, our cost structure or our 
customers' ability to use our services. Such current or future regulations could have a material adverse effect on our business 
and we may not be able to obtain or renew permits or other approvals in the future.

26

Difficult conditions in the global capital markets, the credit markets and the economy in general could negatively affect

our business and results of operations.

Our business may be negatively impacted by adverse economic conditions or future disruptions in the global financial 
markets. Included among these potential negative impacts are reduced energy demand and lower prices for our services and 
increased difficulty in collecting amounts owed to us by our customers which could reduce our access to credit markets, raise 
the cost of such access or require us to provide additional collateral to our counterparties. Our ability to access available 
capacity under our revolving credit facility could be impaired if one or more of our lenders fails to honor its contractual 
obligation to lend to us. If financing is not available when needed, or is available only on unfavorable terms, we may be unable 
to implement our business plans or otherwise take advantage of business opportunities or respond to competitive pressures. 

The amount of cash we have available for distribution to unitholders depends primarily on our cash flow rather than on 

our profitability, which may prevent us from making distributions, even during periods in which we record net income.

The amount of cash we have available for distribution depends primarily upon our cash flow and not solely on profitability,
which will be affected by non-cash items. As a result, we may make cash distributions during periods when we record losses for 
financial accounting purposes and may not make cash distributions during periods when we record net earnings for financial 
accounting purposes.

The revenue in our Processing & Logistics segment largely depends on the amount of natural gas that our customers 

actually deliver to our natural gas processing plants.

As of December 31, 2016, approximately 99% of our reserved capacity at our Casper and Douglas natural gas processing 

plants was subject to firm or volumetric fee contracts, with the majority of the fee revenue being based on the volumes actually 
processed (the remaining 1% was subject to commodity sensitive contracts such as percent of proceeds or keep whole 
processing contracts). On these volumetric fee contracts, our revenue is largely tied to the amount of natural gas that our 
customers actually deliver to our Casper and Douglas plants for processing. Unlike many pipeline transportation customers, our 
natural gas processing customers are not generally subject to "take or pay" obligations. Thus, if our natural gas processing 
customers do not produce natural gas and deliver that natural gas to our processing plants to be processed, revenue for our 
Processing & Logistics segment will decline. As natural gas, crude oil or NGL prices decline, which was the case from the 
second half of 2014 through the first half of 2016, our customers will likely make less money from the production of natural 
gas, crude oil or NGLs than it costs them to produce it. If that happens, our customers may not continue to produce natural gas 
and our revenue will decline. The decreased commodity prices in late 2014 through 2016 contributed to a significant drop in 
actual and anticipated volumes from several producers from which TMID receives natural gas for processing. If a gradual 
recovery of commodity prices and a corresponding increase in volumes over time to TMID does not occur, we could have an 
impairment of the goodwill at the TMID reporting unit, which is a component of our Processing & Logistics segment, and our 
revenue will decline. In addition, the fees our customers pay to reserve capacity at our processing plants may not deter those 
customers from processing their natural gas volumes at other facilities, with whom they may have had prior arrangements or 
otherwise.

We are exposed to direct commodity price risk with respect to some of our processing revenues, and our exposure to 

direct commodity price risk may increase in the future.

Our Processing & Logistics segment operates under three types of contracts, two of which directly expose our cash flows 
to increases and decreases in the price of natural gas and NGLs: percent of proceeds and keep whole processing contracts. As of 
December 31, 2016, approximately 1% of the reserved capacity in our Processing & Logistics segment was contracted under 
percent of proceeds or keep whole processing contracts. We do not currently hedge the commodity exposure inherent in these 
types of processing contracts, and as a result, our revenues and results of operations are impacted by fluctuations in the prices 
of natural gas and NGLs.

Percent of proceeds processing contracts generally provide upside in high commodity price environments, but result in 
lower margins in low commodity price environments. Under keep whole processing contracts, our revenues and our cash flows 
generally increase or decrease as the prices of natural gas and NGLs fluctuate. The relationship between natural gas prices and 
NGL prices may also affect our profitability. When natural gas prices are low relative to NGL prices, it is more profitable for us 
to process natural gas under keep whole arrangements. When natural gas prices are high relative to NGL prices, it is less 
profitable for us and our customers to process natural gas both because of the higher value of natural gas and the increased cost 
(principally that of natural gas as a feedstock and a fuel) of separating the mixed NGLs from the natural gas. As a result, we 
may experience periods in which higher natural gas prices relative to NGL prices reduce our processing margins or reduce the 
volume of natural gas processed at some of our plants. In addition, NGL prices have historically been related to the market 
price of oil and as a result any significant changes in oil prices could also indirectly impact our operations. Indirectly, reduced 
commodity prices impact us through reduced exploration and production activity, which results in fewer opportunities for new 
business to offset natural volume declines. NGL and natural gas prices are volatile and are impacted by changes in the supply 
and demand for NGLs and natural gas, as well as market uncertainty. From the second half of 2014 through the first half of 

27

2016, natural gas and crude oil prices declined substantially and these declines directly and indirectly resulted in lower 
processing volumes and realizations on our percent of proceeds and keep whole processing contracts.

Our success depends on the supply and demand for natural gas and crude oil.

The success of our business is in many ways impacted by the supply and demand for natural gas and crude oil. For 
example, our business can be negatively impacted by sustained downturns in supply and demand for natural gas and crude oil 
in the markets that we serve, including reductions in our ability to renew contracts on favorable terms and to construct new 
infrastructure. Further, a portion of the demand for our water business services depends substantially on the level of 
expenditures by the oil and gas industry for the exploration, development and production of oil and natural gas reserves. These
expenditures are generally dependent on the industry's view of future oil and natural gas prices and are sensitive to the 
industry's view of future economic growth and the resulting impact on demand for oil and natural gas. Declines, as well as 
anticipated declines, in oil and gas prices could also result in project modifications, delays or cancellations, general business 
disruptions, and delays in, or nonpayment of, amounts that are owed to us. These effects could have a material adverse effect on 
our financial condition, results of operations and cash flows.

One of the major factors that will impact natural gas demand will be the potential growth of the demand for natural gas in 
the power generation market, particularly driven by the speed and level of existing coal-fired power generation that is replaced 
with natural gas-fired power generation. One of the major factors impacting domestic natural gas and crude oil supplies has 
been the significant growth in unconventional sources such as shale plays and the continued progression of hydraulic fracturing 
technology. The supply and demand for natural gas and crude oil, and therefore the future rate of growth of our business, 
depends on these and many other factors outside of our control, including, but not limited to:

•

•

•

•

•

•

•

•

•

•

•

•

adverse changes in general global economic conditions;

adverse changes in domestic regulations;

technological advancements that may drive further increases in production and reduction in costs of developing crude 
oil and natural gas shale plays;

the price and availability of other forms of energy, including alternative energy which may benefit from government 
subsidies;

prices for natural gas, crude oil and NGLs;

decisions of the members of the Organization of the Petroleum Exporting Countries, or OPEC, regarding price and 
production controls;

increased costs to explore for, develop, produce, gather, process and transport natural gas or crude oil;

weather conditions, seasonal trends and hurricane disruptions;

the nature and extent of, and changes in, governmental regulation, for example GHG legislation, taxation and 
hydraulic fracturing; 

perceptions of customers on the availability and price volatility of our services and natural gas and crude oil prices, 
particularly customers' perceptions on the volatility of natural gas and crude oil prices over the long-term; 

capacity and transportation service into, or out of, our markets; and

petrochemical demand for NGLs.

The oil and gas industry historically has experienced periodic downturns, and from the second half of 2014 through the 
first half of 2016 experienced a sustained period of decline and volatility in natural gas and crude oil prices. Any prolonged 
downturns in the oil and gas industry could result in a reduction in demand for our services and could adversely affect our 
financial condition, results of operations and cash flows.

Any significant decrease in available supplies of hydrocarbons in our areas of operation, or redirection of existing 
hydrocarbon supplies to other markets, could adversely affect our business and operating results. If recent lower commodity 
prices are prolonged beyond our contract lives, we will likely experience lower throughput volumes and reduced cash flows.

Our business is dependent on the continued availability of natural gas and crude oil production and reserves. Production 
from existing wells and natural gas and crude oil supply basins with access to our assets will naturally decline over time. The
amount of natural gas and crude oil reserves underlying these wells may also be less than anticipated, and the rate at which 
production from these reserves declines may be greater than anticipated. Accordingly, to maintain or increase the contracted 
capacity and/or the volume of products utilizing our assets, our customers must continually obtain adequate supplies of natural 
gas and crude oil.

28

However, the development of additional natural gas and crude oil reserves requires significant capital expenditures by 

others for exploration and development drilling and the installation of production, storage, transportation and other facilities 
that permit natural gas and crude oil to be produced and products delivered to our facilities. In addition, low prices for natural 
gas and crude oil, regulatory limitations, including environmental regulations, or the lack of available capital for these projects 
could have a material adverse effect on the development and production of additional reserves, as well as storage, pipeline 
transportation, and import and export of natural gas and crude oil supplies. The volatility and sustained lower prices for crude 
oil and refined products from the second half of 2014 through the first half of 2016 led to a decline in drilling activity,
production and refining of crude oil, and import levels in these areas. For example, in response to recent declines in crude oil 
prices, a number of producers in our areas of operation significantly reduced their capital budgets and drilling plans in 2015 and 
2016. Even if those producers increase their capital budgets in areas we serve in 2017, it may take months before the increased 
capital spending has the possibility of resulting in increased utilization of our assets. In addition, production may fluctuate for 
other reasons, including, for example, in the case of crude oil, the extent to which the members of OPEC abide by recent 
agreements regarding production controls. Furthermore, competition for natural gas and crude oil supplies to serve other 
markets could reduce the amount of natural gas and crude oil supply available for our customers. Accordingly, to maintain or 
increase the contracted capacity and/or the volume of products utilizing our assets, our customers must compete with others to 
obtain adequate supplies of natural gas and crude oil.

If new supplies of natural gas and crude oil are not obtained to replace the natural decline in volumes from existing supply 
basins, if natural gas and crude oil supplies are diverted to serve other markets, if environmental regulations restrict new natural 
gas and crude oil drilling or if OPEC does not maintain production controls, the overall demand for services on our systems 
will likely decline, which could have a material adverse effect on our ability to renew or replace our current customer contracts 
when they expire and on our business, financial condition, results of operations and ability to make quarterly cash distributions 
to our unitholders.

Our natural gas and crude oil operations are subject to extensive regulation by federal, state and local regulatory 
authorities which could have a material adverse effect on our business, financial condition, and results of operations.

We provide open-access interstate transportation service on our interstate natural gas transportation systems pursuant to 
tariffs approved by the FERC. Our interstate natural gas transportation and storage operations are regulated by the FERC, under 
the NGA, the NGPA, and the EPAct 2005. The Rockies Express Pipeline, the TIGT System and the Trailblazer Pipeline each 
operate under a tariff approved by the FERC that establishes rates and terms and conditions of service to our customers. The
rates and terms of service on the Pony Express System are subject to regulation by the FERC under the ICA, and the Energy
Policy Act of 1992. We provide interstate transportation service on the Pony Express System pursuant to tariffs on file with the 
FERC. Our NGL pipeline that interconnects with Overland Pass Pipeline is leased to a third party who has obtained a waiver 
for itself from the FERC from the tariff, filing and reporting requirements of the ICA, and our NGL pipeline that interconnects 
with the ONEOK's Bakken NGL Pipeline is leased to a third party who is obligated to operate the leased pipeline in 
conformance with the ICA as a FERC regulated NGL pipeline.

Generally, the FERC's authority over natural gas facilities extends to:

•

•

•

•

•

•

•

•

•

•

rates, operating terms and conditions of service;

the form of tariffs governing service;

the types of services we may offer to our customers;

the certification and construction of new, or the expansion of existing, facilities;

the acquisition, extension, disposition or abandonment of facilities;

customer creditworthiness and credit support requirements;

the maintenance of accounts and records;

relationships among affiliated companies involved in certain aspects of the natural gas business;

depreciation and amortization policies; and

the initiation and discontinuation of services.

The FERC's authority over crude oil pipelines is less broad, extending to:

•

•

•

rates, rules and regulations of service;

the form of tariffs governing rates and service;

the maintenance of accounts and records; and

29

•

depreciation and amortization policies.

Interstate natural gas pipelines subject to the jurisdiction of the FERC may not charge rates or impose terms and conditions 

of service that, upon review by the FERC, are found to be unjust, unreasonable, unduly discriminatory, or preferential. The
maximum recourse rates that we may charge for our natural gas transportation and storage services is established through the 
FERC's ratemaking process. The maximum applicable recourse rates and terms and conditions for service are set forth in our 
FERC-approved tariffs.

For example, TIGT filed a general rate case with the FERC pursuant to Section 4 of the NGA in October 2015, which 
resulted in the TIGT Rate Case Settlement that was approved by an order issued by the FERC on November 2, 2016. The TIGT
Rate Case Settlement established settlement rates to be effective through at least April 30, 2019. In the event the assumptions 
relied upon during settlement negotiations were incorrect or the actual costs incurred to operate the TIGT System increase, 
TIGT's cash flows and its results of operations could be adversely affected.

Pursuant to the NGA, existing interstate natural gas transportation and storage rates and terms and conditions of service 
may be challenged by complaint and are subject to prospective change by the FERC. Additionally, rate increases and changes to 
terms and conditions of service proposed by a regulated interstate pipeline may be protested and such increases or changes can 
be delayed and may ultimately be rejected by the FERC. We currently hold authority from the FERC to charge and collect (i) 
"recourse rates" (i.e., the maximum cost-based rates an interstate natural gas pipeline may charge for its services under its 
tariff); (ii) "discount rates" (i.e., rates offered by the natural gas pipeline to shippers at discounts vis-à-vis the recourse rates and 
that fall within the cost-based maximum and minimum rate levels set forth in the natural gas pipeline's tariff); and (iii) 
"negotiated rates" (i.e., rates negotiated and agreed to by the pipeline and the shipper for the contract term that may fall within 
or outside of the cost-based maximum and minimum rate levels set forth in the tariff, and which are individually filed with the 
FERC for review and acceptance). When capacity is available and offered for sale, the rates (which include reservation, 
commodity, surcharges, and FL&U) at which such capacity is sold are subject to regulatory approval and oversight. Regulators 
and customers on our natural gas pipeline systems have the right to protest or otherwise challenge the rates that we charge
under a process prescribed by applicable regulations. The FERC may also initiate reviews of our rates. Customers on our 
interstate natural gas pipeline systems may also dispute terms and conditions contained in our agreements, as well as the 
interpretation and application of our tariffs, among other things.

Rates for interstate crude oil transportation service must be filed as a tariff with the FERC and are subject to applicable 
FERC regulation. The filed tariff rates include contract rates entered into with shippers willing to make long-term commitments 
to the pipeline to support new pipeline capacity. Contract rates generally are not subject to regulation or change by the FERC. 
Non-contract "walk-up" rates are available to uncommitted non-contract shippers and generally are subject to regulation and 
change by the FERC. Interstate crude oil pipelines typically must reserve at least ten percent of their capacity for walk-up 
shippers. Contract tariff rates may be changed by Pony Express on an annual basis to reflect annual FERC index adjustments to 
the extent permitted by contract. Non-contract rates may be adjusted, positively or negatively, on an annual basis pursuant to a 
FERC indexing procedure. An interstate crude oil pipeline may also file new tariff rates at any time, subject to contract 
restrictions and provisions, and FERC regulatory procedures. The filing of any indexed rate increase or other rate increase may 
be protested by parties having standing, subject to applicable regulatory and contract provisions, and thereby be subjected to 
cost-of-service review by the FERC to determine whether the proposed new rate is just and reasonable.

Under the ICA, which applies to the Pony Express System, parties having standing and not restricted by contract may 
protest newly filed rates and terms and conditions of service within a prescribed notice period. The FERC is authorized to 
suspend, subject to refund, the effectiveness of a protested rate for up to seven months while it determines if the protested rate 
is just and reasonable. Our rates may be reduced and we may be required to issue refunds as a result of settlement or by an 
order of the FERC following a hearing finding that a protested rate is unjust and unreasonable. Parties having standing and not 
restricted by contract may file a complaint at any time regarding existing rates and terms and conditions of service. If the 
complaint is not resolved by settlement, the FERC may conduct a hearing and order the crude oil pipeline to make reparations 
going back for up to two years prior to the date on which a complaint was filed if a rate is found to be unjust and unreasonable. 
We cannot guarantee that any new or existing local or joint tariff rate for service on the Pony Express System would not be 
rejected or modified by the FERC, or subjected to refunds or reparations. While the FERC regulates rates and terms and 
conditions of service for transportation of crude oil in interstate commerce by pipeline, state agencies may also regulate 
facilities (including construction, acquisition, disposition, financing, and abandonment), rates, and terms and conditions of 
service for crude oil pipeline transportation in intrastate commerce. Any successful challenge by a regulator or shipper in any of 
these matters could have a material adverse effect on our business, financial condition and results of operations.

30

Pony Express Pipeline's tariff rates may not always be eligible for increases to reflect a FERC index adjustment. For 

example, on November 2, 2016, the FERC issued an Advanced Notice of Proposed Rulemaking, under which the FERC is 
proposing changes to its policies regarding the permissible scope of rate increases based on its annual issuance of changes to 
the generic oil pipeline index, based on specific pipelines' earnings or their specific changes to costs. The FERC's Advanced
Notice of Proposed Rulemaking does not propose specific regulations, and may be followed by a Notice of Proposed 
Rulemaking proposing specific regulations or a Policy Statement announcing new or changed policies.

The FERC's jurisdiction over natural gas facilities extends to the certification and construction of interstate transportation 

and storage facilities, including, but not limited to, acquisitions, facility maintenance and upgrades, expansions, and 
abandonment of facilities and services. With some exceptions applicable to smaller projects, auxiliary facilities, and certain 
facility replacements, prior to commencing construction and/or operation of new or existing interstate natural gas transportation 
and storage facilities, an interstate natural gas pipeline must obtain a certificate authorizing the construction from, or file to 
amend its existing certificate with, the FERC. Typically, a significant expansion project requires review by a number of 
governmental agencies, including state and local agencies, whose cooperation is important in completing the regulatory process 
on schedule. Any delay or refusal by an agency to issue authorizations or permits as requested for one or more of these projects 
may mean that they will be constructed in a manner or with capital requirements that we did not anticipate or that we will not 
be able to pursue these projects. Such delay, modification or refusal could materially and negatively impact the additional 
revenues expected from these projects. The FERC does not regulate the construction, expansion, or abandonment of crude oil 
or NGL pipelines, whether interstate or intrastate, nor the initiation or discontinuation of services on those pipelines, provided 
that the action taken is not discriminatory or preferential among similarly situated shippers.

The FERC has the authority to conduct audits of regulated entities to assess compliance with FERC regulations and 
policies. The FERC also conducts audits to verify that the websites of interstate natural gas pipelines accurately provide 
information on the operations and availability of services on the pipeline. FERC regulations also require entities providing 
interstate natural gas and crude oil transportation services to comply with uniform terms and conditions for service, as set forth 
in publicly available tariffs or, as it concerns natural gas facilities, agreements for transportation and storage services executed 
between interstate pipelines and their customers. Natural gas transportation service agreements are generally required to 
conform, in all material respects, with the standard form of service agreements set forth in the natural gas pipeline's FERC-
approved tariff. The pipeline and a customer may choose to enter into a non-conforming service agreement so long as the 
agreement is filed with, and accepted by, the FERC. In the event that the FERC finds that a natural gas transportation 
agreement, in whole or part, is materially non-conforming, the FERC could reject the agreement or require us to modify the 
agreement, or alternatively require us to modify our tariff so that the non-conforming provisions are generally available to all 
customers. Transportation agreements entered into with crude oil shippers are generally not subject to FERC regulation or 
required to be available for FERC or public review, but the rates and terms and services provided to similarly situated shippers 
may not be unduly discriminatory or preferential.

The FERC has promulgated rules and policies covering many aspects of our natural gas pipeline business, including 
regulations that require us to provide firm and interruptible transportation service on an open access basis that is not unduly 
discriminatory or preferential, provide internet access to current information about our available pipeline capacity and other 
relevant transmission information, and permit pipeline shippers to release contracted transportation and storage capacity to 
other shippers, thereby creating secondary markets for such services. FERC regulations also prevent interstate natural gas 
pipelines from sharing customer information with marketing affiliates, and restrict how interstate natural gas pipelines share 
transportation information with marketing affiliates. FERC regulations require that certain transmission function personnel of 
interstate natural gas pipelines function independently of personnel engaged in natural gas marketing functions. Crude oil 
pipelines subject to the ICA must comply with FERC regulations that require the pipeline to act as a common carrier and not 
engage in undue discrimination or preferential treatment with respect to shippers. The ICA also prevents crude oil and NGL
pipelines from disclosing certain shipper information. 

FERC policies also govern how interstate natural gas pipelines respond to interconnection requests from third party 
facilities, including other pipelines. Generally, an interstate natural gas pipeline must grant an interconnection request upon the 
satisfaction of several conditions. As a consequence, an interstate natural gas pipeline faces the risk that an interconnecting 
third-party pipeline may pose a risk of additional competition to serve a particular market or customer. Failure to comply with 
applicable provisions of the NGA, NGPA, EPAct 2005 and certain other laws, as well as with the regulations, rules, orders, 
restrictions and conditions associated with these laws, could result in the imposition of administrative and criminal remedies, 
including without limitation, revocation of certain authorities, disgorgement of ill-gotten gains, and civil penalties of more than 
$1 million per day, per violation. Violations of the ICA, the Energy Policy Act of 1992, or regulations and orders promulgated 
by the FERC are also subject to administrative and criminal penalties and remedies, including forfeiture and individual liability.

31

In addition, new laws or regulations or different interpretations of existing laws or regulations applicable to our pipeline 
systems or midstream facilities could have a material adverse effect on our business, financial condition, results of operations 
and prospects. For example, the FERC may not continue to pursue its approach of pro-competitive policies as it considers 
matters such as interstate pipeline rates and rules and policies that may affect rights of access to natural gas transportation 
capacity and transportation and storage facilities. We may face challenges to our rates or terms of service in the future. Any
successful challenge could materially and adversely affect our future earnings and cash flows.

The rates and terms and conditions of our regulated assets are subject to review and possible adjustment by federal and 

state regulators, which could adversely affect our business, results of operations, financial condition and ability to make 
quarterly cash distributions to our unitholders.

Our shippers or other interested stakeholders, such as state natural gas utility regulatory agencies, may challenge the rates 

or the terms and conditions of service applicable to our natural gas or crude oil pipeline tariffs, unless they have entered into 
agreements not to challenge such tariffs. The FERC has authority to investigate our rates and terms and conditions of service 
pursuant to NGA Section 5 for natural gas pipelines and the ICA for common carrier oil pipelines. Our crude oil contract 
shippers have generally agreed not to complain or protest rates unless they are in conflict with their contracts. FERC generally 
does not regulate crude oil transportation contracts, but contract rates must be filed with FERC and tariff rules and regulations 
generally apply to contract shippers.

On our interstate crude oil pipeline system, the Pony Express System, shippers may generally challenge new or existing 

rates at any time unless they have contractually agreed not to. As a result of settlement or by order of the FERC following 
hearing, our rates may be reduced. If a shipper files a lawful complaint, and if the complaint is not resolved with that shipper, to 
the extent the FERC determines after hearing that we have collected payment on rates that were not previously just and 
reasonable, we may be required to pay reparations to that shipper for up to two years prior to the date on which a complaint was 
filed. Regardless of the prospective just and reasonable rate, reparations may not be required below the last rates determined by 
the FERC to be just and reasonable. In other words, crude oil pipelines are not required to make reparations that refund 
revenues collected pursuant to rates previously determined to be just and reasonable.

Further, the FERC's actions are subject to court challenge, which may have broader implications for other regulated 
pipelines. For example, in July 2016, the United States Court of Appeals for the District of Columbia Circuit issued its opinion 
in United Airlines, Inc., et al. v. FERC, finding that the FERC had acted arbitrarily and capriciously when it failed to 
demonstrate that permitting an interstate petroleum products pipeline organized as a limited partnership to include an income 
tax allowance in the cost of service underlying its rates in addition to the discounted cash flow return on equity would not result 
in the pipeline partnership owners double-recovering their income taxes. The court vacated the FERC's order and remanded to 
the FERC to consider mechanisms for demonstrating that there is no double recovery as a result of the income tax allowance.  

On December 15, 2016, the FERC issued a Notice of Inquiry regarding the FERC's policy for recovery of income tax costs 

in pipeline cost of service rates. The FERC is seeking comments regarding how to address any double recovery resulting from 
the FERC's current income tax allowance and rate of return policies following the holding in United Airlines, Inc., et al. v.
FERC. The FERC has set a deadline for initial comments to be submitted by March 8, 2017.

There is not likely to be a definitive resolution of these issues for some time, and the ultimate outcome of this proceeding is 
not certain and could result in changes going forward to the FERC's treatment of income tax allowances in the cost of service or 
to the discounted cash flow return on equity. Depending upon the resolution of these issues, the cost of service rates of our 
interstate natural gas pipelines and interstate crude oil pipeline could be affected to the extent we propose new rates or changes 
to our existing rates or if our rates are subject to complaint or challenge by the FERC.

Successful challenges to rates charged on our natural gas and crude oil pipeline systems, or to the terms and conditions of 

service on those systems, could have a material adverse effect on our business, results of operations, financial condition and 
ability to make quarterly cash distributions to our unitholders.

We are subject to numerous hazards and operational risks.

Our operations are subject to all the risks and hazards typically associated with transportation, storage, terminalling, 

processing, gathering and disposing of hydrocarbons and water. These operating risks include, but are not limited to:

•

•

•

•

damage to pipelines, facilities, equipment and surrounding properties caused by hurricanes, earthquakes, tornadoes, 
floods, fires or other adverse weather conditions and other natural disasters and acts of terrorism;

inadvertent damage from construction, vehicles, farm and utility equipment;

uncontrolled releases of crude oil, natural gas and other hydrocarbons or hazardous materials, including water from 
hydraulic fracturing;

leaks, migrations or losses of natural gas and crude oil as a result of the malfunction of equipment or facilities;

32

•

•

•

outages at our facilities;

ruptures, fires, leaks and explosions; and

other hazards that could also result in personal injury and loss of life, pollution and other environmental risks, and 
suspension of operations.

These risks could result in substantial losses due to personal injury and/or loss of life, severe damage to and destruction of 
property and equipment and pollution or other environmental damage. The location of our assets, including certain segments of 
our pipeline systems in or near populated areas, including residential areas, commercial business centers, industrial sites and 
other public gathering areas could increase the level of damages resulting from these risks. Despite the precautions we take, 
events could cause considerable harm to people or property, could result in loss of service available to customers, and could 
have a material adverse effect on our financial condition and results of operations and ability to make distributions to 
unitholders. For example, approximately 10,000 bbls of crude oil were released at the Sterling Terminal in January 2017. Our 
initial review indicates that the release was restricted to the containment area located at the Sterling Terminal and was the result 
of a defective roof drain system on a storage tank. While approximately 9,000 bbls have been recovered and we do not 
anticipate that our total costs to remediate such release will exceed $500,000, our ultimate remediation costs may exceed our 
estimates.

In addition, maintenance, repair and remediation activities could result in service interruptions on segments of our systems 

or alter the operational profile of our systems. Any such service interruption or alteration could limit our ability to satisfy 
customer requirements, could obligate us to provide reservation charge credits to customers for constrained capacity, or could 
allow existing customers to be solicited by other companies for potential new projects that would compete directly with our 
services.

We could be required by regulatory authorities to test or undertake modifications to our systems, operations or both that 
could result in a material adverse impact on our business, financial condition and results of operations. Such actions, including 
those required by PHMSA, could materially and adversely impact our ability to meet contractual obligations and retain 
customers, with a resulting material adverse impact on our business and results of operations, and could also limit or prevent 
our ability to make quarterly cash distributions to our unitholders. Some or all of our costs arising from these operational risks 
may not be recoverable under insurance, contractual indemnification or increases in rates charged to our customers.

Our insurance coverage may not be adequate.

We are not insured or fully insured against all risks that could affect our business, including losses from environmental 
accidents or cyber security threats. For example, we do not maintain business interruption insurance in the type and amount to 
cover all possible losses. In addition, we do not carry insurance for certain environmental exposures, including but not limited 
to potential environmental fines and penalties, certain business interruptions, named windstorm or hurricane exposures and, in 
limited circumstances, certain political risk exposures. Further, in the event there is a total or partial loss of one or more of our 
insured assets, any insurance proceeds that we may receive in respect thereof may be insufficient to effect a restoration of such 
asset to the condition that existed prior to such loss. In addition, we are either not insured or not fully insured with respect to the 
legal proceedings described in Note 18 – Legal and Environmental Matters to the consolidated financial statements and may,
depending upon the circumstances, need to pay self-insured retention amounts prior to having losses covered by the insurance 
providers. The occurrence of any operating risks not fully covered by insurance could have a material adverse effect on our 
business, financial condition, results of operations and cash flows.

Furthermore, we may not be able to maintain or obtain insurance of the type and amount we desire at reasonable rates, and 

we have elected and may elect in the future to self-insure a portion of our risks of loss. As a result of market conditions, 
premiums and deductibles for certain types of insurance policies may substantially increase, and in some instances, certain 
types of insurance could become unavailable or available only for reduced amounts of coverage. Any insurance coverage we do 
obtain may contain large deductibles or fail to cover certain hazards or cover all potential losses.

Our pipeline integrity program may impose significant costs and liabilities on us, while increased regulatory 
requirements relating to the integrity of our pipeline systems may require us to make additional capital and operating 
expenditures to comply with such requirements.

We are subject to extensive laws and regulations related to pipeline integrity. There are, for example, federal requirements 
set by PHMSA for owners and operators of pipelines in the areas of pipeline design, construction, and testing, the qualification 
of personnel and the development of operations and emergency response plans. The rules require pipeline operators to develop 
integrity management programs to comprehensively evaluate their pipelines and take measures to protect pipeline segments 
located in what the rules refer to as HCAs.

33

Our pipeline operations are subject to pipeline safety regulations administered by PHMSA. These regulations, among other 
things, include requirements to monitor and maintain the integrity of our pipeline systems and determine the pressures at which 
our pipeline systems can operate. The Pipeline Safety Act of 2011, enacted January 3, 2012, amends the Pipeline Safety 
Improvement Act of 2002 in a number of significant ways, including:

•

•

•

•

reauthorizing funding for federal pipeline safety programs, increasing penalties for safety violations and establishing 
additional safety requirements for newly constructed pipelines;

requiring PHMSA to adopt appropriate regulations within two years and requiring the use of automatic or remote- 
controlled shutoff valves on new or rebuilt pipeline facilities;

requiring operators of pipelines to verify MAOP and report exceedances within five days; and

requiring studies of certain safety issues that could result in the adoption of new regulatory requirements for new and 
existing pipelines, including changes to integrity management requirements for HCAs, and expansion of those 
requirements to areas outside of HCAs.

In August 2012, PHMSA published rules to update pipeline safety regulations to reflect provisions included in the Pipeline 

Safety Act of 2011, including increasing maximum civil penalties from $0.1 million to $0.2 million per violation per day of 
violation and from $1.0 million to $2.0 million as a maximum amount for a related series of violations as well as changing 
PHMSA's enforcement process. PHMSA recently published an IFR that will increase the per-day violation penalty to $205,638 
and the maximum penalty for a related series of violations to $2,056,380, effective August 1, 2016. On January 13, 2017, 
PHMSA finalized new hazardous liquid pipeline safety regulations extending certain regulatory reporting requirements to all 
hazardous liquid gathering (including oil) pipelines. The final rule requires additional event-driven and periodic inspections, 
requires the use of leak detection systems on all hazardous liquid pipelines, modifies repair criteria, and requires certain 
pipelines to eventually accommodate in-line inspection tools. Because the rule was finalized at the end of the Obama 
Administration, the rule is subject to a regulatory freeze pending review by the Trump Administration, unless exempted due to a 
determination by PHMSA and OMB to allow its effect due to health and safety considerations. Assuming the rule survives the 
review process or is exempted from the regulatory freeze, the rule will become effective six months after its publication in the 
Federal Register, although certain provisions of the Final Rule will have longer compliance periods. In addition, on April 8, 
2016, PHMSA published a notice of proposed rule-making, or NPRM, addressing natural gas transmission and gathering lines. 
The proposed rule would include changes to existing integrity management requirements and would expand assessment and 
repair requirements to pipelines in MCAs, along with other changes. Further, this NPRM would build on the requirements in an 
Advisory Bulletin PHMSA issued in May 2012, which advised pipeline operators of anticipated changes in annual reporting 
requirements and that if they are relying on design, construction, inspection, testing, or other data to determine the pressures at 
which their pipelines should operate, the records of that data must be traceable, verifiable and complete. Comments on the 
NPRM were due on July 7, 2016; further action is pending. We are still monitoring and evaluating the effects of these proposed 
and recently finalized requirements on our operations. 

On June 22, 2016, President Obama signed the PIPES Act, that reauthorizes PHMSA's oil and gas pipeline programs 

through 2019 and provides for the following new mandates, among others:

•

•

•

•

•

Empowers PHMSA to issue emergency orders to individual operators, groups of operators, or the industry upon a 
written finding that an unsafe condition or practice constitutes or is causing an imminent hazard; 

Requires PHMSA, in consultation with other Federal agencies, to issue minimum safety standards for underground
natural gas storage facilities within two years;

Requires PHMSA to conduct post-inspection briefings outlining any concerns within 30 days and providing written 
preliminary findings within 90 days to the extent practicable;

Requires liquid pipeline operators to provide safety data sheets on spilled product to the designated Federal On-Scene 
Coordinator and appropriate State and local emergency responders within 6 hours of telephonic or electronic notice of 
an accident to the National Response Center; and

Requires PHMSA to publish updates on its website every 90 days on the status of an outstanding final rule required by 
a statutory mandate.

On December 14, 2016, PHMSA issued an IFR that addresses safety issues related to downhole facilities, including well
integrity, well bore tubing and casing at underground natural gas storage facilities. The IFR incorporates by reference two of the
American Petroleum Institute’s Recommended Practice standards and mandates certain reporting requirements for operators of
underground natural gas storage facilities. Operators of natural gas storage facilities will have one year from January 18, 2017,
the effective date of the IFR, to implement this first set of PHMSA regulations governing underground storage fields.

34

The ultimate costs of compliance with the integrity management rules are difficult to predict. Changes such as advances of 

in-line inspection tools, identification of additional threats to a pipeline's integrity and changes to the amount of pipe 
determined to be located in HCAs or expansion of integrity management requirements to areas outside of HCAs, such as the 
MCAs proposed by the April 2016 NPRM, can have a significant impact on the costs to perform integrity testing and repairs. 

For example, Trailblazer is currently operating at less than its current MAOP, public notice of which was first provided in 

June 2014. As a result of smart tool surveys in 2014, Trailblazer has identified approximately 25 - 35 miles of pipe that will 
likely need to be repaired or replaced in order for the pipeline to operate at its MAOP of 1,000 pounds per square inch across all 
segments of the Trailblazer Pipeline. Such repair or replacement will likely occur over a period of years, depending upon the 
remediation and repair plan implemented by Trailblazer. Segments of the Trailblazer Pipeline that require full replacement 
could cost as much as $2.7 million per mile and repair costs on sections of the pipeline that do not require full replacement are 
expected to be less on a per mile basis. 

With respect to the approximately 25 - 35 miles of pipe that has been identified, Trailblazer completed 32 excavation digs 
in 2015 at an aggregate cost of approximately $1.3 million. During 2016, Trailblazer completed additional excavation digs and 
replaced approximately 8 miles of pipe at an aggregate cost of approximately $19.0 million. Trailblazer may not recover all 
such out of pocket costs through the available cost recovery options, such as a general rate increase, negotiated rate agreements 
with its customers, or other FERC-approved recovery mechanisms. 

Additionally, in connection with certain crack tool runs on the Pony Express System completed in 2015 and 2016, Pony 
Express completed approximately $9.8 million of remediation in 2016 for anomalies identified on the Pony Express System 
associated with portions of the pipeline converted from natural gas to crude oil service, and expects to complete additional 
remediation in 2017 on the Pony Express System of approximately $9 million.

There can be no assurance as to the amount or timing of future expenditures required to remediate or resolve these issues, 
and actual future expenditures may be different from the amounts we currently anticipate. These integrity issues could have a 
material adverse effect on our business, financial position, results of operations and prospects.

We will continue pipeline integrity testing programs to assess and maintain the integrity of our existing and future pipelines 

as required by the U.S. Department of Transportation regulations. The results of these tests could cause us to incur potentially 
material unanticipated capital and operating expenditures for repairs or upgrades. 

Further, additional laws, regulations and policies that may be enacted or adopted in the future or a new interpretation of 
existing laws and regulations could significantly increase the amount of these expenditures. For example, PHMSA issued an 
Advisory Bulletin in May 2012 which advised pipeline operators that they must have records to document the MAOP for each 
section of their pipeline and that the records must be traceable, verifiable and complete. Locating such records and, in the 
absence of any such records, verifying maximum pressures through physical testing (including hydrotesting) or modifying or 
replacing facilities to meet the demands of verifiable pressures, could significantly increase our costs. TIGT continues to 
investigate and, when necessary, report to PHMSA the miles of pipeline for which it has incomplete records for MAOP. We are 
currently undertaking an extensive internal record review in view of the anticipated PHMSA annual reporting requirements. 
Additionally, failure to locate such records or verify maximum pressures could require us to operate at reduced pressures, 
which would reduce available capacity on our natural gas pipeline systems. These specific requirements do not currently apply 
to crude oil pipelines, but proposed regulations implementing the Pipeline Safety Act of 2011 and future regulations 
implementing the PIPES Act likely will expand the scope of regulation applicable to crude oil pipelines. There can be no 
assurance as to the amount or timing of future expenditures required to comply with pipeline integrity regulation, and actual 
future expenditures may be different from the amounts we currently anticipate. In addition, we may be subject to enforcement 
actions and penalties for failure to comply with pipeline regulations. Revised or additional regulations that result in increased 
compliance costs or additional operating restrictions could have a material adverse effect on our business, financial position, 
results of operations and prospects. In addition, we may be subject to enforcement actions and penalties for failure to comply 
with pipeline regulations.

Our operations are subject to governmental laws and regulations relating to the protection of the environment, which 

may expose us to significant costs, liabilities and expenditures that could exceed our current expectations.

Substantial costs, liabilities, delays and other significant issues related to environmental laws and regulations are inherent 
in our crude oil transportation, storage and terminalling, natural gas transportation, storage and processing, NGL transportation 
and water business services, and as a result, we may be required to make substantial expenditures that could exceed current 
expectations. Our operations are subject to extensive federal, state, and local laws and regulations governing health and safety 
aspects of our operations, environmental protection, including the discharge of materials into the environment, and the security 
of chemical and industrial facilities. These laws include, but are not limited to, the following:

•

CAA and analogous state and local laws, which impose obligations related to air emissions and which the EPA has 
relied upon as authority for adopting climate change regulatory initiatives;

35

•

•

•

•

•

•

•

•

•

•

•

CWA and analogous state and local laws, which regulate discharge of pollutants or fill material from our facilities to 
state and federal waters, including wetlands and which require compliance with state water quality standards;

CERCLA and analogous state and local laws, which regulate the cleanup of hazardous substances that may have been 
released at properties currently or previously owned or operated by us or locations to which we have sent wastes for 
disposal;

RCRA and analogous state and local laws, which impose requirements for the handling and discharge of hazardous 
and nonhazardous solid waste from our facilities;

The SDWA, which ensures the quality of the nation's public drinking water through adoption of drinking water 
standards and controls the waste fluids from disposal wells into below-ground formations;

OSHA and analogous state and local laws, which establish workplace standards for the protection of the health and 
safety of employees, including the implementation of hazard communications programs designed to inform employees 
about hazardous substances in the workplace, potential harmful effects of these substances, and appropriate control 
measures;

NEPA and analogous state and local laws, which require federal agencies to evaluate major agency actions having the 
potential to significantly impact the environment and which may require the preparation of Environmental 
Assessments and more detailed Environmental Impact Statements that may be made available for public review and 
comment;

The Migratory Bird Treaty Act, or MBTA, and analogous state and local laws, which implement various treaties and 
conventions between the United States and certain other nations for the protection of migratory birds and, pursuant to 
which the taking, killing or possessing of migratory birds is unlawful without a permit, thereby potentially requiring 
the implementation of operating restrictions or a temporary, seasonal, or permanent ban in affected areas;

ESA and analogous state and local laws, which seek to ensure that activities do not jeopardize endangered or 
threatened animals, fish and plant species, nor destroy or modify the critical habitat of such species;

Bald and Golden Eagle Protection Act, or BGEPA, and analogous state and local laws, which prohibit anyone, without 
a permit issued by the Secretary of the Interior, from "taking" bald or golden eagles, including their parts, nests, or 
eggs, and defines "take" as "pursue, shoot, shoot at, poison, wound, kill, capture, trap, collect, molest or disturb;"

OPA and analogous state and local laws, which impose liability for discharges of oil into waters of the United States 
and requires facilities which could be reasonably expected to discharge oil into waters of the United States to maintain 
and implement appropriate spill contingency plans; and

National Historic Preservation Act, or NHPA, and analogous state and local laws, which are intended to preserve and 
protect historical and archeological sites.

Various governmental authorities, including but not limited to the EPA, the U.S. Department of the Interior, the U.S. 
Department of Homeland Security, and analogous federal, state and local agencies have the power to enforce compliance with 
these and other similar laws and regulations and the permits and related plans issued under them, oftentimes requiring difficult
and costly actions. Failure to comply with these and other similar laws, regulations, permits, plans and agreements may result in 
the assessment of administrative, civil and criminal penalties, the imposition of remedial obligations, the imposition of stricter 
conditions on or revocation of permits, the issuance of injunctions limiting or preventing some or all of our operations, and 
delays in granting permits.

There is inherent risk of the incurrence of environmental costs and liabilities in our business, some of which may be 
material, due to our handling of the products we transport, process, treat, dispose, gather or store, air emissions related to our 
operations, historical industry operations, and waste disposal practices, such as the prior use of flow meters and manometers 
containing mercury. These activities are subject to stringent and complex federal, state and local laws and regulations governing 
environmental protection, including the discharge of materials into the environment and the protection of plants, wildlife, and 
natural and cultural resources. These laws and regulations can restrict or impact our business activities in many ways, such as 
restricting the way we handle or dispose of wastes or requiring remedial action to mitigate pollution conditions that may be 
caused by our operations or that are attributable to former operators. Joint and several, strict liability may be incurred without 
regard to fault under certain environmental laws and regulations, including but not limited to CERCLA, RCRA and analogous 
state laws, for the remediation of contaminated areas and in connection with spills or releases of materials associated with oil, 
natural gas and wastes on, under, or from our properties and facilities, many of which have been used for midstream activities 
for a number of years, oftentimes by third parties not under our control. We are generally responsible for all liabilities 
associated with the environmental condition of our facilities and assets, whether acquired or developed, regardless of when the 
liabilities arose and whether they are known or unknown. In connection with certain acquisitions and divestitures, we could 
acquire, or be required to provide indemnification against, environmental liabilities that could expose us to material losses, 

36

which may not be covered by insurance. In addition, the steps we could be required to take to bring certain facilities into 
compliance could be prohibitively expensive, and we might be required to shut down, divest or alter the operation of those 
facilities, which might cause us to incur losses. We are currently conducting remediation at several sites to address 
contamination. For these ongoing environmental remediation projects, we spent approximately $497,000 in 2015 and 
approximately $990,000 in 2016, and we have budgeted approximately $718,000 for 2017. 

Private parties, including but not limited to the owners of properties through which our pipelines pass and facilities where 
our wastes are taken for reclamation or disposal, may have the right to pursue legal actions to enforce compliance as well as to 
seek damages for non-compliance with environmental laws, regulations and permits issued thereunder, or for personal injury or 
property damage arising from our operations. Some sites at which we operate are located near current or former third-party 
hydrocarbon storage, processing, operations or other facilities, and there is a risk that contamination has migrated from those 
sites to ours that could result in remedial action. In addition, increasingly strict laws, regulations and enforcement policies could 
materially increase our compliance costs and the cost of any remediation that may become necessary. Our insurance does not 
cover all environmental risks and costs and may not provide sufficient coverage if an environmental claim is made against us.

In June 2013, the EPA extended its National Enforcement Initiatives, enforcement priorities list, including an initiative 
related to Energy Extraction Activities, for 2014 through 2016, and the EPA plans to retain the Energy Extraction Activities
initiative for an additional three years, effective October 2016. We cannot predict what the results of the current initiative or any 
future initiative will be, or whether federal, state or local laws or regulations will be enacted in this area. If new regulations are 
imposed related to oil and gas extraction, the volumes of products, including hydrocarbons and water, that we transport, store, 
gather, dispose and/or process could decline and our results of operations could be materially and adversely affected.

Our business may be materially and adversely affected by changed regulations and increased costs due to stricter pollution 

control requirements or liabilities resulting from non-compliance with required operating or other regulatory permits or plans 
developed thereunder. Also, we might not be able to obtain or maintain from time to time all required environmental regulatory 
approvals for our operations, or may have to implement contingencies or conditions in order to obtain such approvals. If there 
is a delay in obtaining any required environmental regulatory approvals, or if we fail to obtain and comply with them, the 
operation, maintenance or construction of our facilities could be prevented or become subject to additional costs, resulting in 
potentially material adverse consequences to our business, financial condition, results of operations and cash flows. For 
instance, on November 25, 2014, the Wyoming Department of Environmental Quality issued a Notice of Violation for 
violations of Part 60 Subpart OOOO related to the Casper Gas Plant Depropanizer project. TMID had discussed the issues in a 
meeting with WDEQ in Cheyenne on November 17, 2014 and submitted a disclosure on November 20, 2014 detailing the 
regulatory issues and potential violations. The project triggered a modification of the CAA's NSPS Subpart OOOO for the 
entire plant. The project equipment as well as plant equipment subjected to Subpart OOOO was not monitored timely, and 
initial notification was not made timely. Settlement negotiations with WDEQ are currently ongoing. Costs associated with 
penalties and to comply with the terms of any consent decree or settlement, as well as with Subpart OOOO, could be material.

We are also generally responsible for all liabilities associated with the environmental condition of our facilities and assets, 
whether acquired or developed, regardless of when the liabilities arose and whether they are known or unknown. In connection 
with certain acquisitions and divestitures we could acquire, or be required to provide indemnification against, environmental 
liabilities that could expose us to material losses, which may not be covered by insurance. In addition, the steps we could be 
required to take to bring certain facilities into compliance could be prohibitively expensive, and we might be required to shut 
down, divest or alter the operation of those facilities, which might cause us to incur losses. As an example, the Casper Gas Plant 
is part of the Mystery Bridge Road/U.S. Highway 20 Superfund Site also known as Casper Mystery Bridge Superfund Site. 
Remediation work at the Casper Gas Plant has been completed, and we have requested that the portion of the site attributable to 
us be delisted from the National Priorities List. As another example, in August 2011, the EPA and the Wyoming Department of 
Environmental Quality conducted an inspection of the Leak Detection and Repair Program, or LDAR, at the Casper Plant in 
Wyoming. In September 2011, TMID received a letter from the EPA alleging violations of the Standards of Performance of 
Equipment Leaks for Onshore Natural Gas Processing Plant requirements under the CAA. TMID received a letter from the EPA
concerning settlement of this matter in April 2013 and received additional settlement communications from the EPA and 
Department of Justice beginning in July 2014. In July 2014, the EPA provided TMID with a draft Consent Decree that has been 
the basis for subsequent settlement negotiations. Subsequently, the EPA indicated that it intends to join TIGT as a defendant in 
this matter based on TIGT's ownership of the compressor station located adjacent to the Casper Gas Plant in order to address 
alleged LDAR issues at the compressor station. Most recently, the parties held a settlement meeting in August 2015. Following 
the settlement meeting, negotiations are continuing and the parties have entered into tolling agreements that have tolled the 
statute of limitations until January 31, 2017. We are not currently able to estimate the costs that may be associated with a 
settlement or other resolution of this matter, which could be material.

37

We have agreed to a number of conditions in our environmental permits and associated plans, approvals and authorizations 
that require the implementation of environmental habitat restoration, enhancement and other mitigation measures that involve, 
among other things, ongoing maintenance and monitoring. Governmental authorities may require, and community groups and 
private persons may seek to require, additional mitigation measures in the future to further protect ecologically sensitive areas 
where we currently operate, and would operate if our facilities are extended or expanded, or if we construct new facilities, and 
we are unable to predict the effect that any such measures would have on our business, financial position, results of operations 
or prospects.

Also, on June 29, 2015, the EPA and the U.S. Army Corps of Engineers, or Corps, issued a final rule to clarify the term 

"waters of the United States" as it pertains to federal jurisdiction under the CWA. The rule is currently stayed nationwide. 
Although it is unclear how the Corps and the EPA will implement this rule if the stay is lifted, the rule may require additional 
Corps or EPA authorizations or involvement in our future operations, for instance, if we extend our pipelines into or across 
areas (such as certain ditches) newly considered "waters of the United States" under the final rule.

The trend in environmental regulation is to place more restrictions and limitations on activities that may affect the 
environment. There can be no assurance as to the amount or timing of future expenditures for environmental compliance or 
remediation, and actual future expenditures may be materially different from the amounts we currently anticipate. Revised or 
additional regulations that result in increased compliance costs or additional operating restrictions, particularly if those costs are 
not fully recoverable from our customers, could have a material adverse effect on our business, financial position, results of 
operations and prospects.

Climate change regulation at the federal, state or regional levels could result in increased operating and capital costs for

us and reduced demand for our services.

The United States Congress has from time to time considered adopting legislation to reduce emissions of GHGs, and there 

has been a wide-ranging policy debate, both nationally and internationally, regarding the impact of these gases and possible 
means for their regulation. In addition, efforts have been made and continue to be made in the international community toward 
the adoption of international treaties or protocols that would address global climate change issues. In 2015, the United States 
participated in the United Nations Conference on Climate Change, which led to the creation of the Paris Agreement. On April
22, 2016, 175 countries, including the United States, signed the Paris Agreement. The Paris Agreement will require countries to 
review and "represent a progression" in their intended nationally determined contributions, which set GHG emission reduction 
goals, every five years beginning in 2020. Following a finding by the EPA that certain GHGs represent an endangerment to 
human health, the EPA adopted two sets of rules regulating GHG emissions under the CAA, one that requires a reduction in 
emissions of GHGs from motor vehicles and another that regulates emissions of GHGs from certain large stationary sources. 
The EPA also expanded its existing GHG emissions reporting requirements to include upstream petroleum and natural gas 
systems that emit 25,000 metric tons or more of CO2 equivalent per year. Some of our facilities are required to report under this 
rule, and operational and/or regulatory changes could require additional facilities to comply with GHG emissions reporting 
requirements. Furthermore, the EPA adopted a final rule, effective August 2, 2016, imposing more stringent controls on 
methane and volatile organic compounds emissions from oil and gas development, production, and transportation operations 
under the New Source Performance Standard, or NSPS, program. EPA also finalized a rule regarding the alternative criteria for 
aggregating multiple small surface sites into a single source for air quality permitting purposes. This rule could cause small 
facilities, on an aggregate basis, to be deemed a major source, thereby triggering more stringent air permitting processes and 
requirements across the oil and gas industry. On November 10, 2016, the EPA issued a final information collection request that 
requires oil and gas companies to provide EPA with extensive information that EPA could use in crafting regulations of existing 
methane sources under CAA Section 111(d). The BLM also adopted new rules, effective January 17, 2017, to reduce venting, 
flaring, and leaks during oil and natural gas production activities on onshore Federal and Indian leases. In addition, many states 
have already taken legal measures to reduce emissions of GHGs, primarily through the planned development of GHG emission 
inventories and/or regional GHG cap and trade programs. Most of these cap and trade programs work by requiring either major 
sources of emissions, such as electric power plants, or major producers of fuels, to acquire and surrender emission allowances 
with the number of allowances available for purchase reduced each year until the overall GHG emission reduction goal is 
achieved.

The adoption of legislation or regulations imposing reporting or permitting obligations on, or limiting emissions of GHGs 
from, our equipment and operations could require us to incur additional costs to reduce emissions of GHGs associated with our 
operations, could adversely affect our operations in the absence of any permits that may be required to regulate emission of 
GHGs, or could adversely affect demand for the crude oil and natural gas we gather, process, or otherwise handle. For instance, 
EPA's recently finalized NSPS rules or future rules under CAA Section 111(d) could result in the direct regulation of GHGs 
associated with our operations, including the operations of Rockies Express. We are not able at this time to estimate such 
increased costs; however, they could be significant. While we may be able to recover some or all of such increased costs in the 
rates charged by our processing facilities, such recovery of costs is uncertain and may depend on the terms of our contracts with 
our customers.

38

If new laws or regulations that significantly restrict GHGs are adopted, such laws could also make it more difficult or 
costly for our customers to operate, which could reduce our customers' production and therefore the demand for our services. 
While we are not able at this time to estimate such additional costs, as is the case with similarly situated entities in the industry,
they could be significant for us. Restrictions on GHG emissions could also reduce the volume of natural gas that our customers 
produce, and could thereby adversely affect our revenues and results of operations. Compliance with such rules could also 
generally result in additional costs, including increased capital expenditures and operating costs, for us and our customers, 
which could ultimately decrease end-user demand for our services and could have a material adverse effect on our business. In 
addition, to the extent financial markets view climate change and GHG emissions as a financial risk, this could materially and 
adversely impact our cost of and access to capital. Legislation or regulations that may be adopted to address climate change, or 
incentives to conserve energy or use alternative energy sources, could also affect the markets for our services by making natural 
gas and crude oil products less desirable than competing sources of energy.

Increased regulation of hydraulic fracturing and other oil and natural gas processing operations could affect our 
operations and result in reductions or delays in production by our customers, which could have a material adverse impact 
on our revenues.

A sizeable portion of our customers' production comes from hydraulically fractured wells. Hydraulic fracturing is an 
important and common practice that is used to stimulate production of hydrocarbons from tight formations. The process 
typically involves the injection of water, sand and a small percentage of chemicals under pressure into the formation to fracture 
the surrounding rock and stimulate production. The process is regulated by state agencies, typically the state's oil and gas 
commission; however, the EPA has asserted federal regulatory authority over certain hydraulic fracturing activities involving 
diesel under the SDWA and has released draft permitting guidance for hydraulic fracturing activities that use diesel in fracturing 
fluids in those states where the EPA is the permitting authority. A number of federal agencies, including the EPA and the U.S. 
Department of Energy, are analyzing, or have been requested to review, a variety of environmental issues associated with 
hydraulic fracturing. For example, on May 19, 2014, the EPA published an advance notice of rulemaking under the Toxic
Substances Control Act, to gather information regarding the potential regulation of chemical substances and mixtures used in 
oil and gas exploration and production. In May 2016, the EPA issued final rules that update new source performance standard 
requirements and that will impose more stringent controls on methane and volatile organic compounds emissions from oil and 
gas development and production operations, including hydraulic fracturing and other well completion activity. The EPA also 
issued a final rule in June 2016 that prohibits the discharge of hydraulic fracturing wastewater from onshore unconventional oil 
and gas extraction facilities into publicly owned sewage treatment plants. Also, effective June 24, 2015, the BLM adopted rules 
regarding well stimulation, chemical disclosures, water management, and other requirements for hydraulic fracturing on federal 
and Indian lands, but a Wyoming federal judge struck down the rules in June 2016, finding that the BLM lacked congressional 
authority to promulgate them. The BLM is appealing this decision to the U.S. Court of Appeals for the Tenth Circuit. The BLM 
also adopted new rules effective January 17, 2017, to reduce venting, flaring, and leaks during oil and natural gas production 
activities on onshore federal and Indian leases.

Congress from time to time has considered the adoption of legislation to provide for federal regulation of hydraulic 
fracturing under the SDWA and to require disclosure of the chemicals used in the hydraulic fracturing process. In addition, 
some states, including those in which we operate, have adopted, and other states are considering adopting, regulations that 
could impose more stringent disclosure and/or well construction requirements on hydraulic fracturing operations. Local 
government also may seek to adopt ordinances within their jurisdictions regulating the time, place and manner of drilling 
activities in general or hydraulic fracturing activities in particular, and in some cases, may seek to ban hydraulic fracturing 
entirely. Some state and local authorities have considered or imposed new laws and rules related to hydraulic fracturing, 
including temporary or permanent bans, additional permit requirements, operational restrictions and chemical disclosure 
obligations on hydraulic fracturing in certain jurisdictions or in environmentally sensitive areas. Other governmental agencies, 
including the U.S. Department of Energy and the EPA, have evaluated or are evaluating various other aspects of hydraulic 
fracturing such as the potential environmental effects of hydraulic fracturing on drinking water and groundwater. On December 
13, 2016, the EPA released a study of the potential adverse effects that hydraulic fracturing may have on water quality and 
public health, concluding that there is scientific evidence that hydraulic fracturing activities potentially can impact drinking 
water resources in the United States under some circumstances.

If new laws or regulations that significantly restrict hydraulic fracturing are adopted, such laws could make it more difficult
or significantly more costly for our customers to perform fracturing to stimulate production from tight formations. Restrictions 
on hydraulic fracturing could also reduce the volume of crude oil, natural gas or other hydrocarbons that our customers 
produce, and could thereby adversely affect our revenues and results of operations. Compliance with such rules could also 
generally result in additional costs, including increased capital expenditures and operating costs, for us and our customers, 
which could ultimately decrease end-user demand for our services and could have a material adverse effect on our business.

39

Our produced water disposal operations may be subject to additional regulation and liability or claims of environmental 

damages.

We operate produced water disposal wells, which are regulated under the federal SDWA as Class II wells and under state 

laws. State laws and regulations that govern these operations can be more stringent than the SDWA. In addition, the possibility 
exists that stricter laws, regulations or enforcement policies could significantly increase our compliance costs and the cost of 
any remediation that may become necessary. We may also incur material environmental costs and liabilities. Furthermore, our 
insurance may not provide sufficient coverage in the event an environmental claim is made against us. In addition, although the 
disposal wells have received certain governmental regulatory licenses, permits or approvals, this does not shield us from 
potential claims from third parties claiming contamination of their water supply or other environmental damages. Remediation 
of environmental contamination or damages can be extremely costly and such costs, if we are found liable, may have a material 
adverse effect on our business, financial condition and results of operations.

Produced water injection well operations and hydraulic fracturing may cause induced seismicity.

State and federal regulatory agencies recently have focused on a possible connection between hydraulic fracturing related 

activities and the increased occurrence of seismic activity. When caused by human activity, such events are called induced 
seismicity. In a few instances, operators of produced water injection wells in the vicinity of seismic events have been ordered to 
reduce produced water injection volumes or suspend operations. Some state regulatory agencies, including those in Colorado 
and Texas, have modified their regulations to account for induced seismicity. Regulatory agencies at all levels are continuing to 
study the possible linkage between oil and gas activity and induced seismicity. In 2015, the United States Geological Study 
identified eight states, including Colorado, Oklahoma and Texas, with areas of increased rates of induced seismicity that could 
be attributed to fluid injection or oil and gas extraction. In addition, a number of lawsuits have been filed, most recently in 
Oklahoma, alleging that produced water disposal well operations have caused damage to neighboring properties or otherwise 
violated state and federal rules regulating waste disposal. The Oklahoma Corporation Commission has also adopted a plan 
calling for mandatory reductions in oil and gas wastewater disposal well volumes, the implementation of which has involved 
reductions of injection or shut-ins of disposal wells. These developments could result in additional regulation and restrictions 
on the use of produced water injection wells and hydraulic fracturing. Such regulations and restrictions could have a material 
adverse effect on our business, financial condition and results of operations.

We are exposed to costs associated with lost and unaccounted for volumes.

A certain amount of natural gas and crude oil may be lost or unaccounted for in normal operations in connection with their 

transportation across a pipeline system. Under our tariffs and contractual arrangements with our customers we are entitled to 
retain a specified volume of natural gas and crude oil in order to compensate us for such lost and unaccounted for volumes, as 
well as the natural gas used to run our natural gas compressor stations, which we refer to collectively as fuel usage. Our 
pipeline tariffs currently contain fuel usage true-up mechanisms. The use of fuel (natural gas, electric and lost and unaccounted 
for gas) trackers on the Rockies Express Pipeline, the TIGT System, and the Trailblazer Pipeline, while minimizing risk over 
time, nevertheless leaves the systems exposed to the possibility of under- or over-collections on an annual basis. The level of 
lost and unaccounted for volumes, and natural gas fuel usage, on our pipeline systems may exceed the natural gas and crude oil 
volumes retained from our customers as compensation for our lost and unaccounted for volumes, and fuel usage, pursuant to 
our tariffs and contractual agreements, and it may be necessary to purchase natural gas or crude oil in the market to make up for 
the difference, which exposes us to commodity price risk. Future exposure to the volatility of natural gas and crude oil prices as 
a result of lost and unaccounted for volume imbalances could have a material adverse effect on our business, financial 
condition, results of operations and ability to make quarterly cash distributions to our unitholders. 

Any significant and prolonged change in or stabilization of natural gas prices could have a negative impact on our 

natural gas storage business.

Historically, natural gas prices have been seasonal and volatile, which has enhanced demand for our storage services. The

natural gas storage business has benefited from significant price fluctuations resulting from seasonal price sensitivity, which 
impacts the level of demand for our services and the rates we are able to charge for such services. On a system-wide basis, 
natural gas is typically injected into storage between April and October when natural gas prices are generally lower and 
withdrawn during the winter months of November through March when natural gas prices are typically higher. However, the 
market for natural gas may not continue to experience volatility and seasonal price sensitivity in the future at the levels 
previously seen. If volatility and seasonality in the natural gas industry decrease, because of increased production capacity or 
otherwise, then demand for our storage services and the prices that we will be able to charge for those services may decline.

In addition to volatility and seasonality, an extended period of high natural gas prices would increase the cost of acquiring 

base gas and likely place upward pressure on the costs of associated storage expansion activities. Alternatively, an extended 
period of low seasonal volatility in natural gas prices could adversely impact storage values for some period of time until 
market conditions adjust. These commodity price impacts could have a negative impact on our business, financial condition, 
results of operations and ability to make distributions to our unitholders.

Certain portions of our transportation, storage, and processing facilities have been in service for several decades. There 

could be unknown events or conditions or increased maintenance or repair expenses and downtime associated with our 
facilities that could have a material adverse effect on our business and results of operations.

Significant portions of our transportation, storage, and processing systems have been in service for several decades. The
age and condition of our facilities could result in increased maintenance or repair expenditures, and any downtime associated 
with increased maintenance and repair activities could materially reduce our revenue. Any significant increase in maintenance 
and repair expenditures or loss of revenue due to the age or condition of our facilities could adversely affect our business and 
results of operations and our ability to make cash distributions to our unitholders.

Our revolving credit facility and the indenture governing our 5.50% senior notes due 2024 contain certain restrictions 

which could adversely affect our business, financial condition, results of operations and ability to make quarterly cash 
distributions to our unitholders.

We are dependent upon certain earnings and cash flow generated by our operations in order to meet our debt service 

obligations. Our revolving credit facility and the indenture governing our 5.50% senior notes due 2024 (the "2024 Notes") 
contain, and any future financing agreements may contain, operating and financial restrictions and covenants that could restrict 
our ability to finance future operations or capital needs, or to expand or pursue our business activities, which may, in turn, limit 
our ability to make cash distributions to our unitholders. 

For example, our revolving credit facility limits our ability to, among other things:

•

•

incur or guarantee additional indebtedness;

redeem or repurchase units or make distributions under certain circumstances;

• make certain investments and acquisitions;

•

•

incur certain liens or permit them to exist;

enter into certain types of transactions with affiliates;

• merge or consolidate with another company; and

•

transfer, sell or otherwise dispose of assets.

Our revolving credit facility also contains covenants requiring us to maintain certain financial ratios. Our ability to meet 

those financial ratios and tests can be affected by events beyond our control, and we cannot assure you that we will meet those 
ratios and tests. Further, our obligations under the revolving credit facility are (i) guaranteed by us and each of our existing and 
subsequently acquired or organized direct or indirect wholly owned domestic subsidiaries, subject to our ability to designate 
certain subsidiaries as "Unrestricted Subsidiaries," and (ii) secured by a first priority lien on substantially all of the present and 
after acquired property owned by us and each guarantor (other than real property interests related to our pipelines).

Similarly, the indenture governing the 2024 Notes contains covenants that, among other things, limit our ability and the 
ability of our restricted subsidiaries to: (i) incur, assume or guarantee additional indebtedness or issue preferred units; (ii) create 
liens to secure indebtedness; (iii) pay distributions on equity interests, repurchase equity securities or redeem subordinated 
securities; (iv) make investments; (v) restrict distributions, loans or other asset transfers from our restricted subsidiaries; 
(vi) consolidate with or merge with or into, or sell substantially all of our properties to, another person; (vii) sell or otherwise 
dispose of assets, including equity interests in subsidiaries; and (viii) enter into transactions with affiliates.

The provisions of our revolving credit facility and indenture governing the 2024 Notes may affect our ability to obtain 
future financing and pursue attractive business opportunities and our flexibility in planning for, and reacting to, changes in 
business conditions. In addition, a failure to comply with the provisions of our revolving credit facility or the indenture 
governing the 2024 Notes, including a failure to meet any of the required financial ratios and tests, could result in a default or 
an event of default that could enable our lenders or the holders of the 2024 Notes to declare the outstanding principal of that 
indebtedness, together with accrued and unpaid interest, to be immediately due and payable, and in the case of the revolving 
credit facility, would prohibit our ability to make quarterly distributions. If the payment of our indebtedness is accelerated and 
we are unable to repay the indebtedness in full, our lenders could foreclose on the assets pledged by us and the guarantors under 
the revolving credit facility. In that case, our assets may be insufficient to repay such indebtedness in full, and our unitholders 
could experience a partial or total loss of their investment.

Tallgrass Equity's ownership in our IDRs, our common units and our general partner interest, are pledged under 

Tallgrass Equity's revolving credit facility.

Tallgrass Equity's direct ownership of 20,000,000 of our common units and its direct ownership of our general partner 

(which owns our IDRs and general partner interest), are pledged as security under Tallgrass Equity's revolving credit facility.
Tallgrass Equity's revolving credit facility contains customary and other events of default. Upon an event of default, the lenders 
under Tallgrass Equity's revolving credit facility could foreclose on Tallgrass Equity's ownership interest in TEP GP and the 
20,000,000 of our common units owned by Tallgrass Equity. This could ultimately result in a change in control of TEP GP,
which would constitute an immediate event of default under our credit facility. This would have a material adverse effect on our 
business, financial condition and results of operations.

Our future indebtedness levels may limit our flexibility to obtain financing and to pursue other business opportunities.

Our level of indebtedness could have important consequences to us, including the following:

•

•

•

•

our ability to obtain additional financing, if necessary, for working capital, capital expenditures, acquisitions or other 
purposes may be impaired or such financing may not be available on favorable terms;

our funds available for operations, future business opportunities and distributions to unitholders will be reduced by 
that portion of our cash flow required to make interest payments on our indebtedness;

we may be more vulnerable to competitive pressures or a downturn in our business or the economy generally; and

our flexibility in responding to changing business and economic conditions may be limited.

Our ability to service our indebtedness depends upon, among other things, our future financial and operating performance, 
which will be affected by prevailing economic conditions and financial, business, regulatory and other factors, some of which 
are beyond our control. If our operating results are not sufficient to service our current or future indebtedness, we will be forced 
to take actions such as reducing distributions, reducing or delaying our business activities, acquisitions, investments or capital 
expenditures, selling assets or seeking additional equity capital. Taking any of these actions is likely to reduce the value of your 
investment. Plus, we may not be able to effect any of these actions on satisfactory terms or at all.

Increases in interest rates could adversely impact our unit price, our ability to issue equity or incur indebtedness for 

acquisitions or other purposes and our ability to make cash distributions at our intended levels.

The interest rate on borrowings under our revolving credit facility float based upon one or more of the prime rate, the U.S. 
federal funds rate or LIBOR. As a result, those borrowings, as well as borrowings under possible future credit facilities or debt 
offerings, could be higher than current levels, causing our financing costs to increase accordingly. We do not currently hedge 
the interest rate risk on borrowings under our revolving credit facility.

As with other yield-oriented securities, our unit price is impacted by the level of our cash distributions and implied 

distribution yield. The distribution yield is often used by investors to compare and rank yield-oriented securities for investment 
decision-making purposes. Therefore, changes in interest rates, either positive or negative, may affect the yield requirements of 
investors who invest in our units, and a rising interest rate environment could have an adverse impact on our unit price, our 
ability to issue equity or incur indebtedness for acquisitions or other purposes and our ability to make cash distributions at our 
intended levels.

Rockies Express has a substantial amount of indebtedness and Rockies Express may not be able to generate a sufficient

amount of cash flow to meet its debt service obligations.

As of December 31, 2016 Rockies Express had approximately $2.575 billion of total indebtedness outstanding. In addition, 

Rockies Express has a revolving credit facility, which will mature on January 31, 2020, with approximately $150 million of 
additional borrowing capacity available as of December 31, 2016.

The scheduled maturities of Rockies Express' outstanding indebtedness balances as of December 31, 2016 are summarized 

as follows (in millions):

The substantial indebtedness held by Rockies Express could have important consequences. For example, it could:

• make it more difficult for Rockies Express to satisfy its obligations with respect to its indebtedness;

•

•

•

•

•

•

increase the vulnerability of Rockies Express to general adverse economic and industry conditions;

limit the ability of Rockies Express to obtain additional financing for future working capital, capital expenditures and 
other general business purposes;

require Rockies Express to dedicate a substantial portion of its cash flow from operations to payments on its 
indebtedness, thereby reducing the availability of cash flow for operations and other purposes;

limit its flexibility in planning for, or reacting to, changes in its business and the industry in which Rockies Express 
operates;

place Rockies Express at a competitive disadvantage compared to its competitors that have less indebtedness; and

have a material adverse effect if Rockies Express fails to comply with the covenants in the indenture relating to its 
notes or in the instruments governing its other indebtedness.

The terms of the indentures governing the existing Rockies Express notes do not restrict the amount of additional 
unsecured indebtedness Rockies Express may incur, and the agreement governing its credit facility permits additional 
unsecured borrowings. If new indebtedness is added to the current indebtedness levels, these related risks could increase.

Rockies Express' ability to make scheduled payments or to refinance its obligations with respect to its indebtedness will 
depend on its financial and operating performance, which, in turn, is subject to prevailing economic conditions and to financial, 
business, and other factors beyond its control. In addition, a significant amount of Rockies Express' revenue in 2016 was 
generated by long-term contracts that expire in 2019 and Rockies Express may not be able to renew or replace expiring 
contracts at favorable rates or on a long-term basis, which may result in lower cash flows in periods subsequent to 2019. We
cannot assure you that Rockies Express' operating performance, cash flow and capital resources will be sufficient for payment 
of its indebtedness in the future. In the event that Rockies Express is required to dispose of material assets or restructure its 
indebtedness to meet its debt service and other obligations, we cannot assure you as to the terms of any such transaction or how 
soon any such transaction could be completed.

If Rockies Express' cash flow and capital resources are insufficient to fund its debt service obligations, it may be forced to 

sell material assets, obtain additional capital, including through capital contributions from its members, or restructure its 
indebtedness. The payment of additional capital contributions by us to Rockies Express to fund such obligations would reduce 
the amount of cash available to make distributions to our unitholders. 

Rockies Express' revolving credit facility contains certain restrictions which could limit its financial flexibility and 

increase its financing costs.

Rockies Express' revolving credit facility contains restrictive covenants that may prevent it from engaging in various 
transactions that Rockies Express deems beneficial and that may be beneficial to Rockies Express. The revolving credit facility 
generally requires Rockies Express to comply with various affirmative and negative covenants, including a limit on the 
leverage ratio (as defined in the credit agreement) of Rockies Express and restrictions on:

•

•

•

•

incurring secured indebtedness;

entering into mergers, consolidations and sales of assets;

granting liens;

entering into transactions with affiliates; and

• making restricted payments.

The instruments governing any future indebtedness may contain similar or more restrictive provisions. Rockies Express' 

ability to respond to changes in business and economic conditions and to obtain additional financing, if needed, may be 
restricted.

We do not own most of the land on which our assets are located, which could disrupt our operations and subject us to 

increased costs.

We do not own in fee but rather have leases, easements, rights-of-way, permits, surface use agreements and licenses for 
most of the land on which our assets are located, and we are therefore subject to the possibility of more onerous terms and/or 
increased costs to retain necessary land use if we do not have valid interests in the land, if such interests in the land lapse or 
terminate or if our facilities are not properly located within the boundaries of such interests in the land. For example, the West
Frenchie Draw treating facility is located on land leased from the Wyoming Board of Land Commissioners pursuant to a 

43

contract that can be terminated at any time. Although many of these rights are perpetual in nature, we occasionally obtain the 
right to construct and operate pipelines on other owners' land for a specific period of time. If we were to be unsuccessful in 
renegotiating our leases, easements, rights-of-way, permits, surface use agreements and licenses, we might incur increased costs 
to maintain our assets, which could have a material adverse effect on our business, results of operations, financial condition and 
ability to make distributions to our unitholders. In addition, we are subject to the possibility of increased costs under our rental 
agreements with landowners, primarily through rental increases and renewals of expired agreements.

Some leases, easements, rights-of-way, permits, surface use agreements and licenses for our assets are shared with other 
pipeline systems and other assets owned by third parties. We or owners of the other pipeline systems or assets may not have 
commenced or concluded eminent domain proceedings for some rights-of-way. In some instances, lands over which leases, 
easements, rights-of-way, permits, surface use agreements and licenses have been obtained are subject to prior liens which have 
not been subordinated to the grants to us.

Our interstate natural gas pipeline systems have federal eminent domain authority. Whether we have the power of eminent 

domain for the Pony Express crude oil pipeline varies from state to state, depending upon the laws of the particular state. 
Regardless, we must compensate landowners for the use of their property, which may include any loss of value to the remainder 
of their property not being used by us, which are sometimes referred to as "severance damages." Severance damages are often 
difficult to quantify and their amount can be significant. In eminent domain actions, such compensation may be determined by 
a court. Our inability to exercise the power of eminent domain could negatively affect our business if we were to lose the right 
to use or occupy the property on which our crude oil or natural gas pipeline systems are located.

A shortage of skilled labor in the midstream industry could reduce labor productivity and increase costs, which could 

have a material adverse effect on our business and results of operations.

The transportation, storage and terminalling of crude oil, the transportation, storage and processing of natural gas, and the 

transportation, gathering and disposal of water requires skilled laborers in multiple disciplines such as equipment operators, 
mechanics and engineers, among others. If we experience shortages of skilled labor in the future, our labor and overall 
productivity or costs could be materially and adversely affected. If our labor prices increase or if we experience materially 
increased health and benefit costs for employees, our results of operations could be materially and adversely affected.

If we fail to develop or maintain an effective system of internal controls, we may not be able to report our financial 
results accurately or prevent fraud, which would likely have a negative impact on the market price of our common units.

Upon the completion of our initial public offering, we became subject to the public reporting requirements of the Securities 
Exchange Act of 1934, as amended. Effective internal controls are necessary for us to provide reliable financial reports, prevent 
fraud and to operate successfully as a publicly traded partnership. Our efforts to develop and maintain our internal controls may 
not be successful, and we may be unable to maintain effective controls over our financial processes and reporting in the future 
or to comply with our obligations under Section 404 of the Sarbanes-Oxley Act of 2002, which we refer to as Section 404. For 
example, Section 404 requires us, among other things, to annually review and report on, and our independent registered public 
accounting firm to attest to, the effectiveness of our internal controls over financial reporting. Any failure to develop, 
implement or maintain effective internal controls or to improve our internal controls could harm our operating results or cause 
us to fail to meet our reporting obligations. Given the difficulties inherent in the design and operation of internal controls over 
financial reporting, we can provide no assurance as to our, or our independent registered public accounting firm's, conclusions 
about the effectiveness of our internal controls, and we may incur significant costs in our efforts to comply with Section 404. 
Ineffective internal controls will subject us to regulatory scrutiny and a loss of confidence in our reported financial information, 
which could have an adverse effect on our business and would likely have a negative effect on the trading price of our units.

New technologies, including those involving recycling of produced water or the replacement of water in fracturing 

fluid, may adversely affect our future results of operations and financial condition.

The produced water disposal industry is subject to the introduction of new waste treatment and disposal techniques and 
services using new technologies including those involving recycling of produced water, some of which may be subject to patent 
protection. As competitors and others use or develop new technologies or technologies comparable to our water business 
services in the future, we may lose market share or be placed at a competitive disadvantage. For example, some companies 
have successfully used propane as the fracturing fluid instead of water. Further, we may face competitive pressure to implement 
or acquire certain new technologies at a substantial cost. Some of our competitors may have greater financial, technical and 
personnel resources than we do, which may allow them to gain technological advantages or implement new technologies before 
we can. Additionally, we may be unable to implement new technologies or products at all, on a timely basis or at an acceptable 
cost. New technology could also make it easier for our customers to vertically integrate their operations or reduce the amount of 
waste produced in oil and natural gas drilling and production activities, thereby reducing or eliminating the need for third-party 
disposal. Limits on our ability to effectively use or implement new technologies, including in our water business services, may 
have a material adverse effect on our business, financial condition and results of operations.

Our business could be negatively impacted by security threats, including cyber security threats, and related disruptions.

We rely on our information technology infrastructure to process, transmit and store electronic information, including 
information we use to safely operate our assets. We may face cyber security and other security threats to our information 
technology infrastructure, which could include threats to our operational and safety systems that operate our pipelines, plants 
and assets. We could face unlawful attempts to gain access to our information technology infrastructure, including coordinated 
attacks from hackers, whether state-sponsored groups, "hacktivists," or private individuals. The age, operating systems or 
condition of our current information technology infrastructure and software assets and our ability to maintain and upgrade such 
assets could affect our ability to resist cyber security threats. We could also face attempts to gain access to information related 
to our assets through unauthorized access by targeting acts of deception against individuals with legitimate access to physical 
locations or information, otherwise known as "social engineering."

Our information technology infrastructure is critical to the efficient operation of our business and essential to our ability to 
perform day-to-day operations. Breaches in our information technology infrastructure or physical facilities, or other disruptions, 
could result in damage to our assets, service interruptions, safety incidents, damage to the environment, potential liability or the 
loss of contracts, and have a material adverse effect on our operations, financial position, results of operations and prospects.

If we are unable to protect our information and telecommunication systems against disruptions or failures, our 

operations could be disrupted.

We rely extensively on computer systems to process transactions, maintain information and manage our business. 
Disruptions in the availability of our computer systems could impact our ability to service our customers and adversely affect
our sales and results of operations. We are dependent on internal and third-party information technology networks and systems, 
including the Internet, wired, and wireless communications, to process, transmit and store electronic information. Our computer 
systems are subject to damage or interruption due to system replacements, implementations and conversions, power outages, 
computer or telecommunication failures, computer viruses, security breaches, catastrophic events such as fires, tornadoes, 
snowstorms and floods and usage errors by our employees, consultants, and contractors. If our computer systems are damaged 
or cease to function properly, we may have to make a significant investment to fix or replace them, and we may have 
interruptions in our ability to service our customers. Although we attempt to eliminate or reduce these risks by using redundant 
systems, this disruption caused by the unavailability of our computer systems could nevertheless significantly disrupt our 
operations or may result in financial damage or loss due to, among other things, lost or misappropriated information.

Our investment in Rockies Express is a minority interest and could be adversely affected by our lack of sole decision-

making authority.

As a minority-interest partner in Rockies Express, we do not control Rockies Express. Thus, our investment in Rockies 
Express involves risks that are not present when we are able to exercise control over an asset, including the possibility that the 
other members of Rockies Express might become bankrupt, fail to fund their required capital contributions or otherwise attempt 
to make business decisions with respect to Rockies Express that we do not believe are in its best interest. Moreover, under the 
Rockies Express limited liability company agreement, we are required to provide certain capital contributions in order to fund 
expenditures contemplated by Rockies Express' annual budget, and may be required to provide capital contributions under 
certain circumstances specified in the Rockies Express limited liability company agreement if determined to be reasonably 
necessary by a vote of Rockies Express' members. 

The other members of Rockies Express may have economic or other business interests or goals that are inconsistent with 
our business interests or goals. The Rockies Express limited liability company agreement expressly permits Rockies Express 
members, including Tallgrass Development, to make decisions with respect to their ownership interest without taking into 

45

account the interests of Rockies Express or any other member of Rockies Express, and we do not have a voting trust or other 
arrangement in place requiring us or Tallgrass Development to vote jointly. Under the limited liability company agreement of 
Rockies Express, as amended, substantially all matters are decided by a vote of 80% of the membership interests, other than 
certain fundamental decisions that require a vote of 90% of the membership interests. As a result, all of the decisions of the 
Rockies Express members effectively require unanimous approval of all three members of Rockies Express, including Tallgrass
Development and Phillips 66.

Our membership interest in Rockies Express is subject to a right of first refusal, which may make it more difficult to sell 

our interest in Rockies Express in the future.

Under the terms of Rockies Express' limited liability company agreement, if any member desires to transfer its membership 

interest to an unaffiliated third party, each other member first has a right to purchase its proportionate share of the membership 
interest being sold. If we desire to sell all or any portion of our interest in Rockies Express in the future, we will be required to 
first offer the sale of our membership interest to the other members, who will have 30 days to elect to purchase their 
proportionate interest before any sale or transfer to a third party may be consummated. This requirement could make it difficult
for us to sell our interest in Rockies Express.

Risks Inherent in an Investment in Us 

Our general partner and its affiliates, including Tallgrass Equity, TEGP and Tallgrass Energy Holdings, have conflicts 
of interest with us and limited duties to us and our unitholders, and they may favor their own interests to the detriment of us 
and our other common unitholders.

Tallgrass Equity owns our general partner and appoints all of the officers and directors of our general partner. TEGP owns 

a 36.94% membership interest in, and is the managing member of, Tallgrass Equity. TEGP Management is TEGP's general 
partner. Tallgrass Energy Holdings is the sole member of TEGP Management and is also the general partner of Tallgrass
Development.

All of our current officers and a majority of the current directors of our general partner are also officers and/or directors of 
Tallgrass Equity, TEGP Management and Tallgrass Energy Holdings. Certain of our directors are also officers or principals of 
Kelso or EMG, whose affiliated entities, along with certain members of our management, own and control Tallgrass Energy
Holdings. Although our general partner has a duty to manage us in a manner that is beneficial to us and our unitholders, the 
officers and directors of our general partner have a fiduciary duty to manage our general partner in a manner that is in the best 
interests of its owner, Tallgrass Equity. Conflicts of interest will arise between our general partner and its direct and indirect 
owners, on the one hand, and us and our unitholders, on the other hand. In resolving these conflicts of interest, our general 
partner may favor its own interests and the interests of its direct and indirect owners over our interests and the interests of our 
unitholders. These conflicts include the following situations, among others: 

•

•

•

•

•

Neither our partnership agreement nor any other agreement requires Tallgrass Equity, TEGP Management, Tallgrass
Energy Holdings or their respective direct and indirect owners to pursue a business strategy that favors us, and the 
officers and directors of Tallgrass Energy Holdings, TEGP Management and Tallgrass Equity may have a fiduciary 
duty to make these decisions in the best interests of Tallgrass Energy Holdings, TEGP Management and Tallgrass
Equity and their respective direct and indirect owners, respectively, which may be contrary to our interests. Tallgrass
Energy Holdings, TEGP Management or Tallgrass Equity may choose to shift the focus of their investment and growth 
to areas not served by our assets.

Tallgrass Energy Holdings, TEGP Management and Tallgrass Equity their respective direct and indirect owners, and 
their respective affiliates are not limited in their ability to compete with us and, other than Tallgrass Development's 
obligation to offer us certain assets (if Tallgrass Development decides to sell such assets) pursuant to the right of first 
offer under the TEP Omnibus Agreement, may offer business opportunities or sell midstream assets to third parties 
without first offering us the right to bid for them.

Our general partner is allowed to take into account the interests of parties other than us, such as Tallgrass Energy
Holdings, its direct and indirect owners, and their respective affiliates in resolving conflicts of interest and exercising 
certain rights under our partnership agreement, which has the effect of limiting its duty to our unitholders.

All of the current officers and a majority of the current directors of our general partner are also officers and/or 
directors of Tallgrass Energy Holdings and may owe fiduciary duties to Tallgrass Energy Holdings and Tallgrass
Development. Accordingly, these officers will devote significant time to the business of Tallgrass Development.

Our partnership agreement replaces the fiduciary duties that would otherwise be owed by our general partner with 
contractual standards governing its duties, limits our general partner's liabilities and restricts the remedies available to 
our unitholders for actions that, without such limitations, might constitute breaches of fiduciary duty.

Except in limited circumstances, our general partner has the power and authority to conduct our business without 
unitholder approval. 

Disputes may arise under our commercial agreements with Tallgrass Development and its affiliates.

Our general partner determines the amount and timing of asset purchases and sales, borrowings, issuance of additional 
partnership securities and the creation, reduction or increase of reserves, each of which can affect the amount of cash 
available for distribution to our unitholders. 

Our general partner determines the amount and timing of any capital expenditures and whether a capital expenditure is 
classified as a maintenance capital expenditure, which reduces operating surplus, or an expansion or investment capital 
expenditure, which does not reduce operating surplus. This determination can affect the amount of cash that is 
distributed to our unitholders. 

Our general partner determines which costs incurred by it are reimbursable by us. 

Our general partner may cause us to borrow funds in order to permit the payment of cash distributions, even if the 
purpose or effect of the borrowing is to make incentive distributions. 

Our partnership agreement permits us to classify up to $40 million as operating surplus, even if it is generated from 
asset sales, non-working capital borrowings or other sources that would otherwise constitute capital surplus. This cash 
may be used to fund distributions on our general partner units or to our general partner in respect of the IDRs. 

Our partnership agreement does not restrict our general partner from causing us to pay it or its affiliates for any 
services rendered to us or entering into additional contractual arrangements with any of these entities on our behalf. 

Our general partner may limit its liability regarding our contractual and other obligations. 

Our general partner may exercise its right to call and purchase all of the common units not owned by it and its 
affiliates if they own more than 80% of the common units. 

Our general partner controls the enforcement of the obligations that it and its affiliates owe to us, including Tallgrass
Development's and its affiliates' obligations under the TEP Omnibus Agreement and their commercial agreements with 
us.

Our general partner decides whether to retain separate counsel, accountants or others to perform services for us. 

Our general partner may transfer its IDRs without unitholder approval. 

Our general partner may elect to cause us to issue common units to it in connection with a resetting of the target
distribution levels related to our general partner's IDRs without the approval of the conflicts committee of the board of 
directors of our general partner or our unitholders. This election may result in lower distributions to our common 
unitholders in certain situations. 

Affiliates of our general partner are not limited in their ability to compete with us and have limited obligations to offer

us the opportunity to acquire additional assets or businesses, which could limit our ability to grow and could adversely affect
our results of operations and cash available for distribution to our unitholders. 

Affiliates of our general partner, including Kelso, EMG, Tallgrass Equity and its affiliates and Tallgrass Energy Holdings 

and its affiliates, including Tallgrass Development, are not prohibited from owning assets or engaging in businesses that 
compete directly or indirectly with us. In addition, in the future, affiliates of our general partner and the entities owned or 
controlled by affiliates of our general partner, including Tallgrass Development, may acquire, construct or dispose of additional 
midstream or other assets and may be presented with new business opportunities, without any obligation to offer us the 
opportunity to purchase or construct such assets or to engage in such business opportunities, other than Tallgrass Development's 
obligation to offer us certain assets (if Tallgrass Development decides to sell such assets) pursuant to the right of first offer
under the TEP Omnibus Agreement. While affiliates of our general partner may offer us the opportunity to buy these or other 
additional assets, these affiliates of our general partner, including Tallgrass Development, are not contractually obligated to do 
so, other than as described above, and we are unable to predict whether or when such opportunities may arise.

47

Pursuant to the terms of our partnership agreement, the doctrine of corporate opportunity, or any analogous doctrine, does 

not apply to our general partner, its executive officers and directors or any of its affiliates, including Tallgrass Development. 
Any such person or entity that becomes aware of a potential transaction, agreement, arrangement or other matter that may be an 
opportunity for us will not have any duty to communicate or offer such opportunity to us. Any such person or entity will not be 
liable to us or to any limited partner for breach of any fiduciary duty or other duty by reason of the fact that such person or 
entity pursues or acquires such opportunity for itself, directs such opportunity to another person or entity or does not 
communicate such opportunity or information to us. This may create actual and potential conflicts of interest between us and 
affiliates of our general partner, including Tallgrass Development, and result in less than favorable treatment of us and our 
common unitholders. 

Reimbursements due to our general partner and its affiliates for services provided to us or on our behalf will reduce 

cash available for distribution to our common unitholders. The amount and timing of such reimbursements will be 
determined by our general partner.

Under our partnership agreement and the TEP Omnibus Agreement, we will reimburse our general partner and Tallgrass

Energy Holdings and its affiliates for certain expenses incurred on our behalf, including administrative costs, such as 
compensation expense for those persons who provide services necessary to run our business, and insurance expenses. Our 
partnership agreement and the TEP Omnibus Agreement each provide that our general partner will determine in good faith the 
expenses that are allocable to us. The reimbursement of expenses and payment of fees, if any, to our general partner and 
Tallgrass Energy Holdings and its affiliates will reduce the amount of available cash to pay cash distributions to our common 
unitholders.

Our partnership agreement requires that we distribute our available cash, which could limit our ability to grow and 

make acquisitions. 

Our partnership agreement requires us to distribute our available cash to our unitholders. Accordingly, we will rely 
primarily upon external financing sources, including commercial bank borrowings and the issuance of debt and equity 
securities, to fund our acquisitions and expansion capital expenditures. As a result, to the extent we are unable to finance 
growth externally, our cash distribution policy will significantly impair our ability to grow.

In addition, because we intend to distribute our available cash, our growth may not be as fast as that of businesses that 

reinvest their available cash to expand ongoing operations. To the extent we issue additional units in connection with any 
acquisitions or expansion capital expenditures, the payment of distributions on those additional units may increase the risk that 
we will be unable to maintain or increase our per unit distribution level. There are no limitations in our partnership agreement 
on our ability to issue additional units, including units ranking senior to the common units. The incurrence of additional 
commercial borrowings or other indebtedness to finance our growth strategy would result in increased interest expense, which 
in turn may impact the available cash that we have to distribute to our unitholders. 

While our partnership agreement requires us to distribute our available cash, our partnership agreement, including 

provisions requiring us to make cash distributions contained therein, may be amended. 

While our partnership agreement requires us to distribute our available cash, our partnership agreement, including 
provisions requiring us to make cash distributions therein, may be amended. Our partnership agreement can be amended with 
the consent of our general partner and the approval of a majority of the outstanding common units (including common units 
held by our general partner and its affiliates, including Tallgrass Development and Tallgrass Equity). Tallgrass Development 
and Tallgrass Equity currently own approximately 7.8% and 27.7% of our outstanding common units, respectively.

The NYSE does not require a publicly traded partnership like us to comply with certain of its corporate governance 

requirements.

Our common units are listed on the New York Stock Exchange, or NYSE. Unlike most corporations, we are not required 

by NYSE rules to have, and we do not intend to have, a majority of independent directors on our general partner's board of 
directors or a compensation committee or a nominating and corporate governance committee. Additionally, any future issuance 
of additional common units or other securities, including to affiliates, will not be subject to the NYSE's shareholder approval 
rules. Accordingly, unitholders will not have the same protections afforded to certain corporations that are subject to all of the 
NYSE corporate governance requirements. 

If you are not an eligible taxable holder, you will not be entitled to allocations of income or loss or distributions or 

voting rights on your common units and your common units will be subject to redemption. 

In order to avoid any material adverse effect on the maximum applicable rates that can be charged to customers by our 
subsidiaries on assets that are subject to rate regulation by the FERC or an analogous regulatory body, we have adopted certain 
requirements regarding those investors who may own our common units. Eligible holders are individuals or entities subject to 
United States federal income taxation on the income generated by us or entities not subject to United States federal income 

48

taxation on the income generated by us, so long as all of the entity's owners are subject to such taxation. If a holder of our 
common units (other than affiliates of our general partner) is not a person who fits the requirements to be an eligible taxable 
holder, such holder will not be entitled to receive allocations of income or loss or distributions or voting rights on its units and 
will run the risk of having its units redeemed by us at the market price calculated in accordance with our partnership agreement 
as of the date of redemption. The redemption price will be paid in cash or by delivery of a promissory note, as determined by 
our general partner.

Our partnership agreement replaces our general partner's fiduciary duties to holders of our common units with 

contractual standards governing its duties. 

Our partnership agreement contains provisions that eliminate the fiduciary standards to which our general partner would 

otherwise be held by state fiduciary duty law and replaces those duties with several different contractual standards. For 
example, our partnership agreement permits our general partner to make a number of decisions in its individual capacity, as 
opposed to in its capacity as our general partner, free of any duties to us and our unitholders other than the implied contractual 
covenant of good faith and fair dealing (which provides that a court will enforce the reasonable expectations of the partners 
where the language in the partnership agreement does not provide for a clear course of action). This provision entitles our 
general partner to consider only the interests and factors that it desires and relieves it of any duty or obligation to give any 
consideration to any interest of, or factors affecting, us, our affiliates or our limited partners. Examples of decisions that our 
general partner may make in its individual capacity include: 

•

•

•

•

•

•

•

how to allocate business opportunities among us and its affiliates;

whether to exercise its limited call right; 

whether to seek approval of the resolution of a conflict of interest by the conflicts committee of the board of directors 
of our general partner; 

how to exercise its voting rights with respect to the units it owns; 

whether to elect to reset target distribution levels; 

whether to transfer the IDRs or any units it owns to a third party; and 

whether or not to consent to any merger, consolidation or conversion of the partnership or amendment to the 
partnership agreement. 

In addition, our partnership agreement provides that any construction or interpretation of our partnership agreement and 

any action taken pursuant thereto or any determination, in each case, made by our general partner in good faith, shall be 
conclusive and binding on all unitholders. 

Our partnership agreement restricts the remedies available to holders of our common units for actions taken by our 

general partner that might otherwise constitute breaches of fiduciary duty.

Our partnership agreement contains provisions that restrict the remedies available to unitholders for actions taken by our 

general partner that might otherwise constitute breaches of fiduciary duty under state fiduciary duty law. For example, our 
partnership agreement provides that: 

•

•

•

whenever our general partner, the board of directors of our general partner or any committee thereof (including the 
conflicts committee) makes a determination or takes, or declines to take, any other action in their respective capacities, 
our general partner, the board of directors of our general partner and any committee thereof (including the conflicts 
committee), as applicable, is required to make such determination, or take or decline to take such other action, in good 
faith, meaning that it subjectively believed that the decision was in the best interests of our partnership, and, except as 
specifically provided by our partnership agreement, will not be subject to any other or different standard imposed by 
our partnership agreement, Delaware law, or any other law, rule or regulation, or at equity; 

our general partner will not have any liability to us or our unitholders for decisions made in its capacity as a general 
partner so long as such decisions are made in good faith; 

our general partner and its officers and directors will not be liable for monetary damages to us or our limited partners 
resulting from any act or omission unless there has been a final and non-appealable judgment entered by a court of 
competent jurisdiction determining that our general partner or its officers and directors, as the case may be, acted in 
bad faith or engaged in fraud or willful misconduct or, in the case of a criminal matter, acted with knowledge that the 
conduct was criminal; and 

49

•

our general partner will not be in breach of its obligations under the partnership agreement (including any duties to us 
or our unitholders) if a transaction with an affiliate or the resolution of a conflict of interest is: 

approved by the conflicts committee of the board of directors of our general partner (although our general 
partner is not obligated to seek such approval); 

approved by the vote of a majority of the outstanding common units, excluding any common units owned by 
our general partner and its affiliates;

determined by the board of directors of our general partner to be on terms no less favorable to us than those 
generally being provided to or available from unrelated third parties; or 

determined by the board of directors of our general partner to be fair and reasonable to us, taking into account 
the totality of the relationships among the parties involved, including other transactions that may be 
particularly favorable or advantageous to us. 

In connection with a situation involving a transaction with an affiliate or a conflict of interest, any determination by our 
general partner or the conflicts committee must be made in good faith. If an affiliate transaction or the resolution of a conflict of 
interest is not approved by our common unitholders or the conflicts committee and the board of directors of our general partner 
determines that the resolution or course of action taken with respect to the affiliate transaction or conflict of interest satisfies 
either of the standards set forth in the last two bullets above, then it will be presumed that, in making its decision, the board of 
directors acted in good faith, and in any proceeding brought by or on behalf of any limited partner or the partnership 
challenging such determination, the person bringing or prosecuting such proceeding will have the burden of overcoming such 
presumption.

Holders of our common units have limited voting rights and are not entitled to select our general partner or elect 

members of its board of directors. 

Unlike the holders of common stock in a corporation, unitholders have only limited voting rights on matters affecting our 
business and, therefore, limited ability to influence management's decisions regarding our business. Unitholders have no right 
on an annual or ongoing basis to select our general partner or elect its board of directors. Rather, the board of directors of our 
general partner, including the independent directors, is appointed by Tallgrass Equity, as a result of it owning our general 
partner, and not by our unitholders. Tallgrass Energy Holdings effectively controls our business and affairs through the exercise 
of its rights as the party that controls Tallgrass Equity. Furthermore, if the unitholders are dissatisfied with the performance of 
our general partner, they have little ability to remove our general partner. As a result of these limitations, the price at which the 
common units trade could be diminished because of the absence or reduction of a takeover premium in the trading price. Our 
partnership agreement also contains provisions limiting the ability of unitholders to call meetings or to acquire information 
about our operations, as well as other provisions limiting the unitholders' ability to influence the manner or direction of 
management.

Even if holders of our common units are dissatisfied, they cannot currently remove our general partner without its 

consent.

Unitholders are currently unable to remove our general partner without its consent because our general partner and its 

affiliates own sufficient units to be able to prevent its removal. The vote of the holders of at least 66 2/3% of all outstanding 
common units is required to remove our general partner. Tallgrass Development and Tallgrass Equity currently own 
approximately 7.8% and 27.7% of our outstanding common units, respectively. This gives our affiliates the ability to prevent 
the involuntary removal of our general partner. Cause is narrowly defined to mean that a court of competent jurisdiction has 
entered a final, non-appealable judgment finding our general partner liable for actual fraud or willful misconduct in its capacity 
as our general partner and does not include most cases of charges of poor management of the business. 

Our partnership agreement restricts the voting rights of unitholders owning 20% or more of our common units. 

Unitholders' voting rights are further restricted by a provision of our partnership agreement providing that any units held by 

a person that owns 20% or more of any class of units then outstanding, other than our general partner, its affiliates, their 
transferees, persons who acquired such units with the prior approval of the board of directors of our general partner and 
transferees of any of the foregoing, provided such transferee is an affiliate of the transferor, cannot vote on any matter.

Our general partner interest or the control of our general partner may be transferred to a third party without unitholder 

consent.

Our general partner may transfer its general partner interest to a third party without the consent of the unitholders. 

Furthermore, our partnership agreement does not restrict the ability of Tallgrass Energy Holdings to cause the transfer of all or a 
portion of Tallgrass Equity's ownership interest in our general partner to a third party. For example, on May 12, 2015, Tallgrass
Energy Holdings completed the initial public offering of TEGP that indirectly owns all of our incentive distribution rights, our 

50

general partner interest, and a certain number of our common units. Under this new structure, Tallgrass Energy Holdings 
continues to indirectly control our general partner, but, if, in the future, Tallgrass Energy Holdings no longer controls, directly 
or indirectly, our general partner, then a third party with a controlling interest in our general partner would be in a position to 
replace the board of directors and officers of our general partner with its own designees and thereby exert significant control 
over the decisions made by the board of directors and officers. This effectively permits a "change of control" without the vote 
or consent of the unitholders.

The IDRs of our general partner may be transferred to a third party without unitholder consent. 

Our general partner may transfer its IDRs to a third party at any time without the consent of our unitholders. If our general 

partner transfers its IDRs to a third party but retains its general partner interest, our general partner may not have the same 
incentive to grow our partnership and increase quarterly distributions to unitholders over time as it would if it had retained 
ownership of its IDRs. For example, a transfer of IDRs by our general partner could reduce the likelihood of Tallgrass
Development selling or contributing additional midstream assets to us, because Tallgrass Energy Holdings, Tallgrass
Development's general partner, would have less of an economic incentive to grow our business, which in turn would impact our 
ability to grow our asset base. 

We may issue additional units without unitholder approval, which could negatively impact unitholders' existing 

ownership interests. 

Our partnership agreement does not limit the number of additional limited partner interests, including limited partner 
interests that rank senior to the common units, that we may issue at any time without the approval of our unitholders. The
issuance by us of additional common units or other equity securities of equal or senior rank could have the following effects:

•

•

•

•

•

•

our existing unitholders' proportionate ownership interest in us will decrease; 

the amount of cash available for distribution on each unit may decrease; 

because the amount payable to holders of IDRs is based on a percentage of the total cash available for distribution, the 
distributions to holders of IDRs will increase even if the per unit distribution on common units remains the same; 

the ratio of taxable income to distributions may increase; 

the relative voting strength of each previously outstanding unit may be diminished; and 

the market price of the common units may decline. 

Further, at times during recent years, the capital markets have limited the availability of capital through traditional issuances
of common units. As these periods occur in the future, it may be necessary for us to issue preferred units, convertible units, or
other securities that rank senior to the common units in order to raise capital, which could further magnify the dilutive and other
negative effects on unitholders' existing ownership interests.

Affiliates of our general partner, including Tallgrass Development, may sell units in the public or private markets, and 

such sales could have an adverse impact on the trading price of the common units. 

Tallgrass Development currently holds 5,619,218 common units and Tallgrass Equity, which owns our general partner,
currently holds 20,000,000 common units. In addition, we have agreed to provide our general partner and its affiliates with 
certain registration rights. For example, the 5,619,218 common units owned by Tallgrass Development have been registered 
pursuant to our Form S-3/A (File No. 333-210976) filed with the SEC on May 6, 2016, which became effective May 17, 2016. 
The sale of these units in the public or private markets could have an adverse impact on the price of the common units or on 
any trading market that may develop. For additional information, see Note 12 – Partnership Equity and Distributions to our 
Consolidated Financial Statements in Item 8.—Financial Statements and Supplementary Data in this Form 10-K.

Our general partner may limit its liability regarding our obligations. 

Our general partner may limit its liability under contractual arrangements so that the counterparties to such arrangements 

have recourse only against our assets, and not against our general partner or its assets. Our general partner may therefore cause 
us to incur indebtedness or other obligations that are nonrecourse to our general partner. Our partnership agreement permits our 
general partner to limit its liability, even if we could have obtained more favorable terms without the limitation on liability. In 
addition, we are obligated to reimburse or indemnify our general partner to the extent that it incurs obligations on our behalf. 
Any such reimbursement or indemnification payments would reduce the amount of cash otherwise available for distribution to 
our unitholders. 

51

Our general partner has a limited call right that may require unitholders to sell units at an undesirable time or price. 

If at any time our general partner and its affiliates own more than 80% of the common units, our general partner will have 

the right, which it may assign to any of its affiliates or to us, but not the obligation, to acquire all, but not less than all, of the 
common units held by unaffiliated persons at a price that is not less than their then-current market price, as calculated pursuant 
to the terms of our partnership agreement. As a result, unitholders may be required to sell common units at an undesirable time 
or price and may not receive any return on investment. 

Unitholders may also incur a tax liability upon a sale of your units. Tallgrass Development and Tallgrass Equity, each an 
affiliate of our general partner, currently own approximately 7.8% and 27.7% of our outstanding common units, respectively.

Our general partner, or any transferee holding a majority of the IDRs, may elect to cause us to issue common units to it 

in connection with a resetting of the minimum quarterly distribution and the target distribution levels related to the IDRs, 
without the approval of the conflicts committee of our general partner or our unitholders. This election may result in lower 
distributions to our common unitholders in certain situations. 

The holder or holders of a majority of the IDRs, which is currently our general partner, have the right, at any time when 
there are no subordinated units outstanding and the holders have received incentive distributions at the highest level to which 
they are entitled (48%) for each of the prior four consecutive fiscal quarters (and the amount of each such distribution did not 
exceed adjusted operating surplus for each such quarter), to reset the minimum quarterly distribution and the initial target
distribution levels at higher levels based on our cash distribution at the time of the exercise of the reset election. Following a 
reset election, the minimum quarterly distribution will be reset to an amount equal to the average cash distribution per unit for 
the two fiscal quarters immediately preceding the reset election (such amount is referred to as the "reset minimum quarterly 
distribution"), and the target distribution levels will be reset to correspondingly higher levels based on percentage increases 
above the reset minimum quarterly distribution. We have been paying quarterly cash distributions at the highest distribution 
level (48%) since our distribution with respect to the fourth quarter of 2014. Our general partner has the right to transfer the 
IDRs at any time, in whole or in part, and any transferee holding a majority of the IDRs would have the same rights as our 
general partner with respect to resetting target distributions. 

In the event of a reset of the minimum quarterly distribution and the target distribution levels, the holders of the IDRs will 
be entitled to receive, in the aggregate, the number of common units equal to that number of common units which would have 
entitled the holders to an average aggregate quarterly cash distribution in the prior two quarters equal to the average of the 
distributions on the IDRs in the prior two quarters. Our general partner will also be issued the number of general partner units 
necessary to maintain its general partner interest in us that existed immediately prior to the reset election. We anticipate that our 
general partner would exercise this reset right in order to facilitate acquisitions or internal growth projects that would not 
otherwise be sufficiently accretive to cash distributions per common unit. It is possible, however, that our general partner or a 
transferee could exercise this reset election at a time when it is experiencing, or expects to experience, declines in the cash 
distributions it receives related to its IDRs and may therefore desire to be issued common units rather than retain the right to 
receive incentive distribution payments based on target distribution levels that are less certain to be achieved in the then current 
business environment. This risk could be elevated if our IDRs have been transferred to a third party. As a result, a reset election 
may cause our common unitholders to experience dilution in the amount of cash distributions that they would have otherwise 
received had we not issued common units to our general partner in connection with resetting the target distribution levels. 

Your liability may not be limited if a court finds that unitholder action constitutes control of our business. 

A general partner of a partnership generally has unlimited liability for the obligations of the partnership, except for those 

contractual obligations of the partnership that are expressly made without recourse to the general partner. Our partnership is 
organized under Delaware law, and we conduct business in a number of other states. The limitations on the liability of holders 
of limited partner interests for the obligations of a limited partnership have not been clearly established in some of the other 
states in which we do business. You could be liable for any and all of our obligations as if you were a general partner if a court 
or government agency were to determine that: 

•

•

we were conducting business in a state but had not complied with that particular state's partnership statute; or 

your right to act with other unitholders to remove or replace our general partner, to approve some amendments to our 
partnership agreement or to take other actions under our partnership agreement constitute "control" of our business. 

Unitholders may have liability to repay distributions that were wrongfully distributed to them. 

Under certain circumstances, unitholders may have to repay amounts wrongfully returned or distributed to them. Under 
Section 17-607 of the Delaware Revised Uniform Limited Partnership Act, we may not make a distribution if the distribution 
would cause our liabilities to exceed the fair value of our assets. Delaware law provides that for a period of three years from the 
date of an impermissible distribution, limited partners who received the distribution and who knew at the time of the 
distribution that it violated Delaware law will be liable to the limited partnership for the distribution amount. Transferees of 

52

common units are liable both for the obligations of the transferor to make contributions to the partnership that were known to 
the transferee at the time of transfer and for those obligations that were unknown if the liabilities could have been determined 
from the partnership agreement. Neither liabilities to partners on account of their partnership interest nor liabilities that are non-
recourse to the partnership are counted for purposes of determining whether a distribution is permitted. 

Tax Risks to Common Unitholders

Our tax treatment depends on our status as a partnership for U.S. federal income tax purposes, as well as our not being 

subject to a material amount of entity-level taxation by individual states. If the Internal Revenue Service treats us as a 
corporation for U.S. federal income tax purposes or we become subject to material additional amounts of entity-level 
taxation for state tax purposes, then our cash available for distribution to our unitholders would be substantially reduced.

The anticipated after-tax economic benefit of an investment in the common units depends in part on our being treated as a 
partnership for U.S. federal income tax purposes. We have not requested, and except as described below, do not plan to request, 
a ruling from the Internal Revenue Service, or IRS, on this or any other tax matter affecting us.

Despite the fact that we are a limited partnership under Delaware law, it is possible in certain circumstances for a publicly 

traded partnership such as ours to be treated as a corporation rather than a partnership for U.S. federal income tax purposes. 
Although we do not believe based upon our current operations that we are so treated, a change in our business or a change in 
current law could cause us to be treated as a corporation for U.S. federal income tax purposes or otherwise subject us to 
taxation as an entity.

For example, from time to time, members of the U.S. Congress propose and consider substantive changes to the U.S. 

federal income tax laws that affect publicly traded partnerships. We are unable to predict whether any such changes, or 
proposals, will be considered or will ultimately be enacted or whether judicial or administrative interpretations of applicable 
law will change. Any such changes could negatively impact the value of an investment in our common units. Any modification 
to the U.S. federal income tax laws may be applied retroactively and could make it more difficult or impossible to meet the 
exception for certain publicly traded partnerships to be treated as partnerships for U.S. federal income tax purposes.

On January 24, 2017, final regulations by the IRS and the U.S. Department of the Treasury were published in the Federal
Register that provide industry-specific guidance regarding whether income earned from certain activities will constitute qualifying
income. We believe that we will continue to be able to meet the exception for us to be treated as a partnership for U.S. federal
income tax purposes under the new rules.

If we were treated as a corporation for U.S. federal income tax purposes, we would pay U.S. federal income tax on our 
taxable income at the corporate tax rate, which is currently a maximum of 35%, and would likely pay state and local income tax 
at varying rates. Our distributions would generally be taxed again as corporate dividends (to the extent of our current and 
accumulated earnings and profits), and no income, gains, losses, deductions, or credits would flow through to you. Because a 
tax would be imposed upon us as a corporation, our cash available for distribution to you would be substantially reduced. 
Therefore, if we were treated as a corporation for U.S. federal income tax purposes there would be a material reduction in our 
anticipated cash flow and after tax return to our unitholders, likely causing a substantial reduction in the value of our common 
units.

At the state level, several states are evaluating ways to subject partnerships to entity-level taxation through the imposition 

of state income, franchise and other forms of taxation. Imposition of such a tax on us by any state will reduce the cash available 
for distributions to our unitholders.

Our partnership agreement provides that, if a law is enacted or existing law is modified or interpreted in a manner that 
subjects us to taxation as a corporation or otherwise subjects us to entity-level taxation for federal, state or local income tax 
purposes, the minimum quarterly distribution amount and the target distribution amounts may be adjusted to reflect the impact 
of that law on us.

Our unitholders' share of our income will be taxable to them for U.S. federal income tax purposes even if they do not 

receive any cash distributions from us. 

A unitholder will be treated as a partner who is subject to allocation of taxable income which could be different in amount 

than the cash we distribute. A unitholder's allocable share of our taxable income will be taxable to the unitholder, which may 
require the payment of U.S. federal income taxes and, in some cases, state and local income taxes even if no cash distributions 
are received from us. Our unitholders may not receive cash distributions from us equal to their share of our taxable income or 
even equal to the actual tax liability that results from that income. 

53

If the IRS contests the U.S. federal income tax positions we take, the market for our common units may be adversely 

impacted and the cost of any IRS contest will reduce our cash available for distribution to our unitholders. 

We have not requested a ruling from the IRS with respect to our treatment as a partnership for U.S. federal income tax 
purposes or any other matter affecting us. The IRS may adopt positions that differ from the positions we take, and the IRS's 
positions may ultimately be sustained. It may be necessary to resort to administrative or court proceedings to sustain some or all 
of the positions we take. A court may not agree with some or all of the positions we take. Any contest with the IRS, and the 
outcome of any IRS contest, may have a materially adverse impact on the market for our common units and the price at which 
they trade. In addition, our costs of any contest with the IRS will be borne indirectly by our unitholders and our general partner 
because the costs will reduce our cash available for distribution. 

Tax gain or loss on the disposition of our common units could be more or less than expected. 

If you sell your common units, you will recognize a gain or loss for U.S. federal income tax purposes equal to the 
difference between the amount realized and your tax basis in those common units. Because distributions in excess of your 
allocable share of our net taxable income decrease your tax basis in your common units, some, or all of any of such prior excess 
distributions with respect to the common units you sell will, in effect, become taxable income to you if you sell such common 
units at a price greater than your tax basis in those common units, even if the price you receive is less than your original cost. 
Furthermore, a substantial portion of the amount realized on any sale or other disposition of your common units, whether or not 
representing gain, may be taxed as ordinary income due to potential recapture items, including depreciation recapture. In 
addition, because the amount realized includes a unitholder's share of our nonrecourse liabilities, if you sell your common units, 
you may incur a tax liability in excess of the amount of cash you receive from the sale. 

Tax-exempt entities and non-U.S. persons face unique tax issues from owning our common units that may result in 

adverse tax consequences to them. 

Investment in common units by tax-exempt entities, such as employee benefit plans and individual retirement accounts 

(known as IRAs), and non-U.S. persons raises issues unique to them. For example, virtually all of our income allocated to 
organizations that are exempt from U.S. federal income tax, including IRAs and other retirement plans, will be unrelated 
business taxable income and will be taxable to them. Distributions to non-U.S. persons will generally be reduced by 
withholding taxes at the highest applicable effective tax rate, and non-U.S. persons will be required to file U.S. federal income 
tax returns and pay tax on their share of our taxable income. If you are a tax-exempt entity or a non-U.S. person, you should 
consult a tax advisor before investing in our common units. 

We will treat each purchaser of common units as having the same tax benefits without regard to the actual common 

units purchased. The IRS may challenge this treatment, which could adversely affect the value of the common units. 

Because we cannot match transferors and transferees of common units and because of other reasons, we will adopt 

depreciation and amortization positions that may not conform to all aspects of existing Treasury Regulations. A successful IRS 
challenge to those positions could adversely affect the amount of tax benefits available to you. A successful IRS challenge also 
could affect the timing of these tax benefits or the amount of gain from your sale of common units and could have a negative 
impact on the value of our common units or result in audit adjustments to your tax returns. 

We prorate our items of income, gain, loss and deduction for U.S. federal income tax purposes between transferors and 
transferees of our units each month based upon the ownership of our units on the first day of each month, instead of on the 
basis of the date a particular unit is transferred. The IRS may challenge this treatment, which could change the allocation 
of items of income, gain, loss and deduction among our unitholders. 

We prorate our items of income, gain, loss and deduction for U.S. federal income tax purposes between transferors and 
transferees of our units each month based upon the ownership of our units on the first day of each month, instead of on the basis 
of the date a particular unit is transferred. The use of this proration method may not be permitted under existing Treasury
Regulations, and although the U.S. Treasury Department adopted final Treasury Regulations allowing a similar monthly 
simplifying convention for taxable years beginning on or after August 3, 2015, such regulations do not specifically authorize 
the use of the proration method we have adopted. If the IRS were to challenge this method or new Treasury regulations were 
issued, we may be required to change the allocation of items of income, gain, loss and deduction among our unitholders. 

54

A unitholder whose common units are loaned to a "short seller" to cover a short sale of common units may be 
considered as having disposed of those common units. If so, the unitholder would no longer be treated for U.S. federal 
income tax purposes as a partner with respect to those common units during the period of the loan and may recognize gain 
or loss from the disposition. 

Because a unitholder whose common units are loaned to a "short seller" to cover a short sale of common units may be 
considered as having disposed of the loaned common units, the unitholder may no longer be treated for U.S. federal income tax 
purposes as a partner with respect to those common units during the period of the loan to the short seller and may recognize 
gain or loss from such disposition. Moreover, during the period of the loan to the short seller, any of our income, gain, loss or 
deduction with respect to those common units may not be reportable by the unitholder and any cash distributions received by 
the unitholder as to those common units could be fully taxable as ordinary income. Our unitholders desiring to assure their 
status as partners and avoid the risk of gain recognition from a loan to a short seller should consult a tax advisor to discuss 
whether it is advisable to modify any applicable brokerage account agreements to prohibit their brokers from loaning their 
common units. 

We have adopted certain valuation methodologies in determining a unitholder's allocations of income, gain, loss and 
deduction. The IRS may challenge these methodologies or the resulting allocations, and such a challenge could adversely 
affect the value of our common units.

In determining the items of income, gain, loss and deduction allocable to our unitholders, we must routinely determine the 

fair market value of our assets. Although we may from time to time consult with professional appraisers regarding valuation 
matters, we make many fair market value estimates using a methodology based on the market value of our common units as a 
means to measure the fair market value of our assets. The IRS may challenge these valuation methods and the resulting 
allocations of income, gain, loss and deduction. 

A successful IRS challenge to these methods or allocations could adversely affect the timing or amount of taxable income 

or loss being allocated to our unitholders. It also could affect the amount of gain from our unitholders' sale of common units 
and could have a negative impact on the value of the common units or result in audit adjustments to our unitholders' tax returns 
without the benefit of additional deductions.

The sale or exchange of 50% or more of our capital and profits interests during any twelve-month period will result in 

the termination of our partnership for U.S. federal income tax purposes. 

We will be considered to have technically terminated our partnership for U.S. federal income tax purposes if there is a sale 

or exchange of 50% or more of the total interests in our capital and profits within a twelve-month period. Tallgrass
Development and its direct and indirect owners own a substantial interest in our capital and profits. Therefore, a transfer by 
them of all or a portion of their interests in us could result in a termination of our partnership for U.S. federal income tax 
purposes. For purposes of determining whether the 50% threshold has been met, multiple sales of the same interest will be 
counted only once. Our technical termination would, among other things, result in the closing of our taxable year for all 
unitholders, which would result in us filing two tax returns (and our unitholders could receive two Schedules K-1 if relief was 
not available, as described below) for one fiscal year if the termination occurs on a day other than December 31 and could 
result in a deferral of depreciation deductions allowable in computing our taxable income. In the case of a unitholder reporting 
on a taxable year other than a fiscal year ending December 31, the closing of our taxable year may also result in more than 
twelve months of our taxable income or loss being includable in the unitholder's taxable income for the year of termination. Our 
termination currently would not affect our classification as a partnership for U.S. federal income tax purposes, but instead we 
would be treated as a new partnership for tax purposes. If treated as a new partnership, we must make new tax elections and 
could be subject to penalties if we are unable to determine that a termination occurred. The IRS has announced a publicly 
traded partnership technical termination relief program whereby, if a publicly traded partnership that technically terminated 
requests publicly traded partnership technical termination relief and such relief is granted by the IRS, among other things, the 
partnership will only have to provide one Schedule K-1 to unitholders for the year notwithstanding two partnership tax years. 

As a result of investing in our common units you will likely become subject to state and local taxes and return filing 

requirements in jurisdictions where we operate or own or acquire properties. 

In addition to U.S. federal income taxes, our unitholders will likely be subject to other taxes, including state and local 
taxes, unincorporated business taxes and estate, inheritance or intangible taxes that are imposed by the various jurisdictions in 
which we conduct business or own property now or in the future, even if they do not live in any of those jurisdictions. Our 
unitholders will likely be required to file state and local income tax returns and pay state and local income taxes in some or all 
of these various jurisdictions. Further, our unitholders may be subject to penalties for failure to comply with those 
requirements. We currently own property or conduct business in a number of states, most of which currently impose a personal 
income tax on individuals. Most of these states also impose an income tax on corporations and other entities. As we make 
acquisitions or expand our business, we may own property or conduct business in additional states that impose a personal 
income tax. It is your responsibility to file all federal, state and local tax returns. 

55

Compliance with and changes in tax laws could adversely affect our performance. 

We are subject to extensive tax laws and regulations, including federal and state income tax laws and transactional tax laws 
such as excise, sales/use, payroll, franchise and ad valorem tax laws. New tax laws and regulations and changes in existing tax 
laws and regulations are continuously being enacted that could result in increased tax expenditures in the future. Further, taxing 
authorities may change their application of existing taxes, so that additional entities or transactions may become subject to an 
existing tax. Many of these tax liabilities are subject to audits by the respective taxing authority. These audits may result in 
additional tax payments, as well as interest and penalties. In one such audit, Rockies Express has appealed an excise tax 
assessment on the gross receipts from certain transactions issued by the Ohio Department of Taxation. If the appeal is 
unsuccessful, Rockies Express may be subject to substantial additional excise taxes in the future, and imposition of such excise 
taxes could reduce the cash available for distribution to our unitholders.

We have subsidiaries that are treated as corporations for U.S. federal income tax purposes and subject to corporate level

income taxes and may conduct additional activities in taxable corporate subsidiaries in the future.

Even though we (as a partnership for U.S. federal income tax purposes) are not subject to U.S. federal income tax, we have
subsidiaries that are organized as corporations for U.S. federal income tax purposes. Although these subsidiaries have not previously
generated any material taxable income, we may elect to conduct additional activities in one or more subsidiaries treated as
corporations for U.S. federal income tax purposes in the future that could generate material taxable income. For example, it is
unclear whether and to what extent our share of water business services income from Water Solutions will be treated as qualifying
income. On January 24, 2017, final regulations by the IRS and the U.S. Department of the Treasury were published in the Federal
Register providing that income from water delivery services is not qualifying income unless the partnership providing those services
also collects, cleans, recycles or otherwise disposes of the water after use in accordance with applicable law. While we have not
requested a ruling from the IRS that income from Water Solutions, or a portion of such income, is qualifying income, we may
request such a ruling in the future, although the IRS may be unwilling or unable to provide a favorable ruling in a timely manner
or at all. If it becomes necessary in order to preserve our status as a partnership, we may elect to conduct all or portions of our
Water Solutions business in a taxable corporate subsidiary (see "—Our tax treatment depends on our status as a partnership for
U.S. federal income tax purposes. If the IRS were to treat us as a corporation for U.S. federal income tax purposes, which would
subject us to entity-level taxation, then our cash available for distribution to our unitholders would be substantially reduced.").

The taxable income, if any, of any subsidiary that is treated as a corporation for U.S. federal income tax purposes, is 
subject to corporate-level U.S. federal income taxes, which may reduce the cash available for distribution to us and, in turn, to 
our unitholders. If the IRS or other state or local jurisdictions were to successfully assert that this corporation has more tax 
liability than we anticipate or legislation was enacted that increased the corporate tax rate, the cash available for distribution 
could be further reduced. The income tax return filing positions taken by corporate subsidiaries could require significant 
judgment, use of estimates, and the interpretation and application of complex tax laws. Significant judgment could also be 
required in assessing the timing and amounts of deductible and taxable items. Despite our belief that the income tax return 
positions taken by our corporate subsidiaries would be fully supportable, certain positions may be successfully challenged by 
the IRS, state or local jurisdictions.

If the IRS makes audit adjustments to our income tax returns for tax years beginning after 2017, it may collect any 

resulting taxes (including any applicable penalties and interest) directly from us, in which case our cash available for 
distribution to our unitholders might be substantially reduced.

Pursuant to the Bipartisan Budget Act of 2015, if the IRS makes audit adjustments to our income tax returns for tax years 

beginning after 2017, it may collect any resulting taxes (including any applicable penalties and interest) directly from us. We
will generally have the ability to shift any such tax liability to our general partner and our unitholders in accordance with their 
interests in us during the year under audit, but there can be no assurance that we will be able to (or will choose to) do so under 
all circumstances. If we are required to make payments of taxes, penalties and interest resulting from audit adjustments, our 
cash available for distribution to our unitholders might be substantially reduced.

As of February 15, 2017, there were 64 unitholders of record of our common units. This number does not include 
unitholders whose units are held in trust by other entities. The actual number of beneficial unitholders is greater than the 
number of holders of record. In addition, as of February 15, 2017, our general partner owned all 834,391 of our general partner 
units.

Equity Compensation Plan

See Item 12.—Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters for 

information regarding our Equity Compensation Plan.

Distributions of Available Cash

General. Our partnership agreement requires that, within 45 days after the end of each quarter, we distribute our available 

cash to unitholders of record on the applicable record date, as determined by our general partner.

Definition of Available Cash. The term "available cash" generally means, for any quarter, all cash and cash equivalents on 

hand at the end of that quarter:

•

less the amount of cash reserves established by our general partner to:

provide for proper conduct of business;

comply with applicable law or regulation, any of our debt instruments or other agreements; or

provide funds for distributions to unitholders and to our general partner for any one or more of the next four 
quarters;

•

plus, if our general partner so determines, all or any portion of the cash on hand on the date of distribution of available
cash for the quarter, including cash on hand resulting from working capital borrowings made subsequent to the end of
such quarter.

58

Minimum Quarterly Distribution. We intend to make cash distributions to the holders of common units on a quarterly basis 

in an amount equal to at least the minimum quarterly distribution, or MQD, of $0.2875 per unit or $1.15 per unit on an 
annualized basis, to the extent we have sufficient cash from our operations after establishment of cash reserves and payment of 
fees and expenses, including payments to our general partner and its affiliates. However, there is no guarantee that we will pay 
the MQD on the units in any quarter. Even if our cash distribution policy is not modified or revoked, the amount of 
distributions paid under our policy and the decision to make any distribution is determined by our general partner, taking into 
consideration the terms of our partnership agreement. Our general partner has broad discretion to establish cash reserves that it 
determines are necessary or appropriate to properly conduct our business. These can include cash reserves for future capital and 
maintenance expenditures, reserves to stabilize distributions of cash to our unitholders, reserves to reduce debt or, as necessary,
reserves to comply with the terms of any of our agreements or obligations. We will be prohibited from making any distributions 
to unitholders if it would cause an event of default or if an event of default exists under our credit agreement.

General Partner Interest. Our general partner is currently entitled to approximately 1.14% of all quarterly distributions that 

we make prior to our liquidation based on its ownership of the general partner interest. As of February 15, 2017, our general 
partner interest is represented by 834,391 general partner units. Our general partner has the right, but not the obligation, to 
contribute a proportional amount of capital to us to maintain its general partner interest, up to 2%. The general partner's 
proportionate interest in our quarterly distributions will be reduced if we issue additional units in the future and our general 
partner does not contribute a proportional amount of capital to us to maintain its general partner interest.

Incentive Distribution Rights. As quarterly distributions exceed the MQD and other higher target distribution levels, our 
general partner, as the holder of the IDRs, becomes entitled to increasing percentages (13%, 23% and 48%) of the distributions 
after the MQD. Such higher target distribution levels have been achieved and we have been distributing 48% on the IDRs since 
our distribution with respect to the fourth quarter of 2014. For additional information, see Note 12 – Partnership Equity and 
Distributions to our Consolidated Financial Statements in Item 8.—Financial Statements and Supplementary Data in this Form 
10-K.

Conversion of Subordinated Units. Under the terms of our partnership agreement and upon the payment of our quarterly 
cash distribution to unitholders on February 13, 2015, our subordination period ended. As a result, our 16,200,000 subordinated 
units held by TD converted into common units on a one for one basis on February 17, 2015. The conversion of the subordinated 
units did not impact the aggregate amount of cash distributions paid.

Item 6. Selected Financial Data

The historical financial statements included in this Annual Report reflect the combined results of operations of TIGT and 

TMID, which we refer to collectively as "our Predecessor." As discussed further in Note 2 – Summary of Significant Accounting
Policies to the accompanying consolidated financial statements, the financial statements of our Predecessor for historical 
periods beginning after November 13, 2012 have been recast to reflect the operations of Trailblazer, which was acquired on 
April 1, 2014, and Pony Express, of which TEP acquired a controlling 33.3% membership interest effective September 1, 2014.

In connection with our initial public offering on May 17, 2013, TD contributed to us its equity interests in our Predecessor.

The term "TEP Pre-Predecessor" refers to the Tallgrass Energy Partners Pre-Predecessor, which represents the combined 
results of operations of TIGT and TMID that were owned by Kinder Morgan Energy Partners, LP ("TEP Pre-Predecessor
Parent") prior to November 13, 2012, at which date TEP Pre-Predecessor Parent sold those assets, among others, to TD. 
Financial information for the TEP Pre-Predecessor has not been recast to reflect the operations of Trailblazer and Pony 
Express. The following discussion analyzes the financial condition and results of operations of our Predecessor. In certain 
circumstances and for ease of reading we discuss the financial results of the Predecessor as being "our" financial results
during historic periods, although TIGT and TMID were owned by TD from November 13, 2012 until May 17, 2013, Trailblazer
was owned by TD from November 13, 2012 to March 31, 2014, and Pony Express was wholly-owned by TD from November 13, 
2012 to August 31, 2014. As used in this Annual Report, unless the context otherwise requires, "we," "us," our," the 
"Partnership," "TEP" and similar terms refer to Tallgrass Energy Partners, LP, together with its consolidated subsidiaries.

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

Historical periods have been recast to reflect the operations of Trailblazer, which was acquired on April 1, 2014, and Pony 

Express, of which TEP acquired a controlling 33.3% membership interest effective September 1, 2014. TEP's subsequent 
acquisitions of an additional 33.3% and 31.3% membership interest in Pony Express on March 1, 2015 and January 1, 2016, 
respectively, represent acquisitions of noncontrolling interests. As a result, financial information for periods prior to those 
transactions have not been recast to reflect the additional 33.3% and 31.3% membership interests. In certain circumstances
and for ease of reading we discuss the financial results of these entities prior to their respective acquisitions as being "our" 
financial results during historic periods, although Trailblazer was owned by TD from November 13, 2012 to March 31, 2014, 
and Pony Express was wholly-owned by TD from November 13, 2012 to August 31, 2014. 

The following discussion and analysis of our financial condition and results of operations should be read in conjunction 

with the consolidated financial statements and related notes thereto included elsewhere in this Annual Report. 

Overview

We are a publicly traded, growth-oriented limited partnership formed in 2013 to own, operate, acquire and develop 
midstream energy assets in North America. Our operations are located in and provide services to certain key United States 
hydrocarbon basins, including the Denver-Julesburg, Powder River, Wind River, Permian and Hugoton-Anadarko Basins and 
the Niobrara, Mississippi Lime, Eagle Ford, Bakken, Marcellus, and Utica shale formations.

We intend to continue to leverage our relationship with TD and utilize the significant experience of our management team 

to execute our growth strategy of acquiring midstream assets from TD and third parties, increasing utilization of our existing 
assets and expanding our systems through construction of additional assets. Our reportable business segments are:

•

•

•

Crude Oil Transportation & Logistics—the ownership and operation of a FERC-regulated crude oil pipeline system 
and crude oil storage and terminalling facilities;

Natural Gas Transportation & Logistics—the ownership and operation of FERC-regulated interstate natural gas 
pipelines and integrated natural gas storage facilities; and

Processing & Logistics—the ownership and operation of natural gas processing, treating and fractionation facilities, 
the provision of water business services primarily to the oil and gas exploration and production industry and the 
transportation of NGLs.

Additional information about our operations and assets is contained in the business overview included in Item 1.—

Business under "Overview" and "Our Assets."

Summary of Results for the Year Ended December 31, 2016

During 2016, we completed the acquisitions of an additional 31.3% membership interest in Pony Express, a 25% 

membership interest in Rockies Express and an additional 8% membership interest in Water Solutions. In addition, we issued 
$400 million in aggregate principal amount of 5.50% senior notes due 2024 (the "2024 Notes") and received aggregate net 
proceeds of $427.7 million from the issuance of 10,113,695 common units through a combination of public and private 
issuances.

Net income attributable to partners for the year ended December 31, 2016 was $263.5 million, with Adjusted EBITDA and 

Distributable Cash Flow (each as defined below under "Non-GAAP Financial Measures") of $423.5 million and $408.5
million, respectively, compared to net income attributable to partners for the year ended December 31, 2015 of $160.5 million,
with Adjusted EBITDA and Distributable Cash Flow of $252.3 million and $220.5 million, respectively. The increase in net 
income, Adjusted EBITDA, and Distributable Cash Flow was largely driven by the ramping up of commercial operations at 
Pony Express and the lateral in Northeast Colorado, our acquisition of an additional 31.3% membership interest in Pony 
Express on January 1, 2016, and our acquisition of a 25% membership interest in Rockies Express on May 6, 2016, as 
discussed further under "Results of Operations" below.

Recent Developments

Distribution Declared

On January 24, 2017, the Board of Directors of our general partner declared a cash distribution for the quarter 

ended December 31, 2016 of $0.815 per common unit. The distribution was paid on February 14, 2017, to unitholders of record 
on February 3, 2017.

62

Exercise of Call Option and Repurchase of Additional Common Units Owned by TD

On February 1, 2017, we exercised the remainder of the call option granted by TD, as discussed in Note 4 – Acquisitions,
covering 1,703,094 common units for a cash payment of $72.4 million, and we repurchased 736,262 common units from TD
for a negotiated cash payment of approximately $35.3 million, or $47.99 per common unit, which repurchase was approved by 
the conflicts committee of the board of directors of our general partner. These 2,439,356 common units in the aggregate equal 
the number of common units sold under our equity distribution agreements since November 3, 2016 and were deemed canceled 
and no longer issued and outstanding as of such transaction date.

Acquisition of Tallgrass Terminals, LLC and Tallgrass NatGas Operator, LLC

Effective January 1, 2017, we acquired 100% of the issued and outstanding membership interests in Terminals and 100%

of the issued and outstanding membership interests in NatGas from TD for total cash consideration of $140 million.

Terminals owns and operates several fully operational assets providing storage capacity and additional injection points for 

the Pony Express System, including the Sterling Terminal near Sterling, Colorado, with approximately 1.3 million bbls of 
storage capacity and the Buckingham Terminal in Weld County, Colorado, with four truck unloading skids capable of receiving 
up to approximately 16,000 bbls per day. Terminals also owns a 20% interest in the Deeprock Development, which owns the 
Cushing Terminal in Cushing, Oklahoma, with approximately 2.3 million bbls of storage capacity. In addition, Terminals owns 
projects currently under development, including approximately 550 acres in Cushing, Oklahoma and approximately 250 acres 
in Guernsey, Wyoming which is under development to provide additional storage capacity and other potential service 
opportunities.

NatGas is the operator of the Rockies Express Pipeline and receives a fee from Rockies Express as compensation for its 

services.

Ultra Settlement

In early 2016, Ultra defaulted on its firm transportation service agreement with Rockies Express for approximately 0.2
Bcf/d through November 11, 2019 on the Rockies Express Pipeline and on April 14, 2016, Rockies Express filed a lawsuit 
against Ultra for breach of contract and damages in Harris County, Texas, seeking approximately $303 million in damages and 
other relief. On April 29, 2016, Ultra and certain of its debtor affiliates filed for protection under Chapter 11 of the U.S. 
Bankruptcy Code in U.S. Bankruptcy Court for the Southern District of Texas, which operated as a stay of the Harris County 
state court proceeding.

On January 12, 2017, Rockies Express and Ultra entered an agreement to settle Rockies Express' approximately $303 

million claim against Ultra's bankruptcy estate. The settlement agreement includes Ultra's agreement to: (i) make a cash 
payment to Rockies Express of $150 million in accordance with the plan of reorganization, but no later than October 30, 2017; 
and (ii) enter a new, seven-year firm transportation agreement with Rockies Express commencing December 1, 2019, for west-
to-east service of 0.2 Bcf/d at a rate of approximately $0.37, or approximately $26.8 million annually. The settlement is part of 
Ultra's Chapter 11 reorganization plan, which must be submitted to the U.S. Bankruptcy Court for approval.

Factors and Trends Impacting Our Business

We expect to continue to be affected by certain key factors and trends described below. Our expectations are based on 

assumptions made by us and information currently available to us. To the extent our underlying assumptions about, or 
interpretations of, available information prove to be incorrect, our actual results may vary materially from our expected results. 
See also Item 1A.—Risk Factors.

Long-Term U.S. Crude Oil and Natural Gas Prospects

Crude oil, natural gas, and products derived from both continue to be critical components of energy supply and demand in 

the United States. Although crude oil and natural gas prices declined significantly from the second half of 2014 through the first 
half of 2016, and could experience further declines or remain at or near current levels for the foreseeable future, we 
nevertheless believe that prices may have stabilized during the latter part of 2016 and that the long-term prospects for continued 
crude oil and natural gas production increases are favorable.

63

We believe long-term growth will be driven, in part, by a combination of increased domestic demand resulting from 
population and economic growth, higher industrial consumption in the U.S. spurred by the lower commodity price of feedstock 
and fuel, and a desire to reduce domestic reliance on imports. One example is that we expect natural gas to gradually displace 
coal-fired electricity generation due to the low prices of natural gas and stricter environmental regulations on the mining and 
burning of coal. We expect productivity of oil and natural gas wells to continue increasing over the long-term in some basins 
across the United States because of the increasing precision and efficiency of horizontal drilling and hydraulic fracturing in oil 
and natural gas extraction. We also believe there is a substantial inventory of drilled but uncompleted wells in the basins we 
serve, including the Bakken shale and Denver-Julesburg basin, that are likely to be completed and turned into production as 
commodity prices continue to recover and stabilize.

Current Commodity Environment

Starting in the second half of 2014, the prices of crude oil, natural gas, and NGLs were extremely volatile and declined 

significantly. This volatility and downward pressure on commodity prices continued through the first half of 2016. Such 
volatility and reduced prices impact our business in several ways.

Demand for our services depends, in part, on the development of additional natural gas and crude oil reserves by third 

parties. This requires significant capital expenditures by others to install facilities that extract natural gas and crude oil. 
However, low commodity prices may result in a lack of available capital for these types of expenditures. To the extent our 
customers cannot finance these activities, we expect they may be less likely to enter into demand based, long-term firm fee 
contracts until there is further commodity price recovery and stability in the markets. The commodity price declines over the 
past two years may also negatively impact the financial condition of our customers and could impact their ability to meet their 
financial obligations to us.

Additionally, lower commodity prices may lead to reduced utilization of our assets. For example, reduced utilization could 
result in increased deficiency balances held by customers of our Pony Express System. For additional information, see Item 1A.
—Risk Factors, "The Throughput and Deficiency Agreements for the Pony Express System and some of our service agreements
with respect to our water business services contain provisions that can reduce the cash flow stability that the agreements were
designed to achieve."

Growth Associated with Acquisitions and Expansion Projects

Growth associated with acquisitions

We believe that we are well-positioned to grow through accretive acquisitions. We intend to pursue acquisition 
opportunities from third parties as they become available and expect to continue to acquire assets from TD's portfolio of 
midstream assets, which includes TD's 50% interest in the Rockies Express Pipeline. We expect TD to retain its 2% ownership 
interest in Pony Express for the foreseeable future. Pursuant to the TEP Omnibus Agreement, TD granted us the right of first 
offer to acquire each of the remaining Retained Assets if TD decides to sell those assets. Other than its obligations under the 
TEP Omnibus Agreement, TD is under no obligation to offer to sell us additional assets or to pursue acquisitions jointly with 
us, and we are under no obligation to buy any assets from TD or pursue any such joint acquisitions. However, given the 
significant economic interest in us held by TD and its affiliates, we believe TD will be incentivized to offer us the opportunity 
to acquire its assets. 

Growth associated with expansion projects

We also believe that we are well positioned to increase volumes to our systems through cost-effective capacity expansions 
and other methods for improving efficiency, such as the use of drag reducing agents in our crude oil pipelines. For example, in 
2014, Pony Express completed the conversion and construction of its approximately 698-mile crude oil pipeline commencing 
in Guernsey, Wyoming, and terminating in Cushing, Oklahoma. In 2015, Pony Express completed the construction of an 
approximately 66-mile lateral in Northeast Colorado commencing in Weld County, Colorado, and interconnecting with the 
pipeline just east of Sterling, Colorado. In January 2017, Rockies Express placed in service the Rockies Express Zone 3 
Capacity Enhancement Project that added an incremental 0.8 Bcf/d of east-to-west capacity within Zone 3 of the Rockies 
Express Pipeline.

Energy Capital Markets and Interest Rates

During the second half of 2015 and into mid-2016, the energy credit markets experienced a material increase in the yields 

for long-term debt, which caused an issuance of senior unsecured notes to be a less attractive financing option until the third 
quarter of 2016, when we were able to issue the 2024 Notes. At the same time, the downturn in commodity prices generally 
limited the availability of capital through traditional public issuances of common units for much of 2016. While the downturn 
did not change our business plans, including our growth through acquisitions and expansion projects, it did temporarily alter 
some of our financing strategies. 

64

In addition, the Federal Reserve increased short-term interest rates which marginally impacted the rates on our floating rate 

revolving credit facility. If the economy continues to strengthen, it is likely that monetary policy will continue to tighten, 
resulting in higher interest rates to counter possible inflation. If this occurs, interest rates on our floating rate credit facilities 
and future offerings in the debt capital markets could be at higher rates, causing our financing costs to increase accordingly. For 
additional information, please read Item 7A.—Quantitative and Qualitative Disclosures About Market Risk.

How We Evaluate Our Operations 

We evaluate our results using, among other measures, contract profile and volumes, operating costs and expenses, Adjusted

EBITDA and Distributable Cash Flow. Adjusted EBITDA and Distributable Cash Flow are non-GAAP measures and are 
defined below.

Contract Profile and Volumes

Our results are driven primarily by the volume of crude oil transportation, storage and terminalling capacity, natural gas 

transportation and storage capacity, NGL transportation capacity, and water transportation, gathering and disposal capacity 
under firm fee contracts, as well as the volume of natural gas that we process and the fees assessed for such services. 

Operating Costs and Expenses

The primary components of our operating costs and expenses that we evaluate include cost of sales, cost of transportation 

services, operations and maintenance and general and administrative costs. Our operating expenses are driven primarily by 
expenses related to the operation, maintenance and growth of our asset base.

Adjusted EBITDA and Distributable Cash Flow

Adjusted EBITDA and Distributable Cash Flow are non-GAAP supplemental financial measures that management and 
external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies, may 
use to assess:

•

•

•

•

our operating performance as compared to other publicly traded partnerships in the midstream energy industry,
without regard to historical cost basis or, in the case of Adjusted EBITDA, financing methods;

the ability of our assets to generate sufficient cash flow to make distributions to our unitholders;

our ability to incur and service debt and fund capital expenditures; and

the viability of acquisitions and other capital expenditure projects and the returns on investment of various expansion 
and growth opportunities.

We believe that the presentation of Adjusted EBITDA and Distributable Cash Flow provides useful information to 

investors in assessing our financial condition and results of operations. Adjusted EBITDA and Distributable Cash Flow should 
not be considered alternatives to net income, operating income, net cash provided by operating activities or any other measure 
of financial performance or liquidity presented in accordance with GAAP, nor should Adjusted EBITDA and Distributable Cash 
Flow be considered alternatives to available cash, operating surplus, distributions of available cash from operating surplus or 
other definitions in our partnership agreement. Adjusted EBITDA and Distributable Cash Flow have important limitations as 
analytical tools because they exclude some but not all items that affect net income and net cash provided by operating 
activities. Additionally, because Adjusted EBITDA and Distributable Cash Flow may be defined differently by other companies 
in our industry, our definition of Adjusted EBITDA and Distributable Cash Flow may not be comparable to similarly titled 
measures of other companies, thereby diminishing their utility.

Non-GAAP Financial Measures

We generally define Adjusted EBITDA as net income excluding the impact of interest, income taxes, depreciation and 
amortization, non-cash income or loss related to derivative instruments, non-cash long-term compensation expense, impairment 
losses, gains or losses on asset or business disposals or acquisitions, gains or losses on the repurchase, redemption or early 
retirement of debt, and earnings from unconsolidated investments, but including the impact of distributions from 
unconsolidated investments. We also use Distributable Cash Flow, which we generally define as Adjusted EBITDA, plus 
deficiency payments received from or utilized by our customers and preferred distributions received from Pony Express in 
excess of its distributable cash flow attributable to our net interest, less cash interest expense, maintenance capital expenditures, 
distributions to noncontrolling interests in excess of earnings allocated to noncontrolling interests, and certain cash reserves 
permitted by our partnership agreement, to analyze our performance.

65

Maintenance capital expenditures are cash expenditures incurred (including expenditures for the construction or 
development of new capital assets) that we expect to maintain our long-term operating income or operating capacity. These
expenditures typically include certain system integrity, compliance and safety improvements, and are presented net of 
noncontrolling interest and reimbursements. As discussed in Note 2 – Summary of Significant Accounting Policies, prior to 
December 31, 2015, we received preferred distributions from Pony Express. Effective January 1, 2016 with our acquisition of 
an additional 31.3% membership interest in Pony Express, distributable cash flow from Pony Express is distributed pro rata 
based on ownership. Pony Express collects deficiency payments for barrels committed by the customer to be transported in a 
month but not physically received for transport or delivered to the customers' agreed upon destination point. These deficiency 
payments are recorded as a deferred liability until the barrels are physically transported and delivered by TEP. Earnings at Pony 
Express prior to December 31, 2015 were allocated between TEP and noncontrolling interests in accordance with a substantive 
profit sharing arrangement rather than pro rata by ownership. Distributions made by Pony Express to its noncontrolling 
interests reduce the Distributable Cash Flow available to TEP.

66

Distributable Cash Flow and Adjusted EBITDA are not presentations made in accordance with GAAP. The following table 
presents a reconciliation of Adjusted EBITDA to net income and net cash provided by operating activities and a reconciliation 
of Distributable Cash Flow to net cash provided by operating activities, the most directly comparable GAAP financial

Year Ended December 31, 2016 Compared to the Year Ended December 31, 2015

Revenues. Total revenues were $605.1 million for the year ended December 31, 2016, compared to $536.2 million for the 
year ended December 31, 2015, which represents an increase of $68.9 million, or 13%, in total revenues. The overall increase
in revenue was largely driven by increased revenues of $76.3 million in the Crude Oil Transportation & Logistics segment, 
partially offset by decreased revenues of $4.3 million and $2.8 million in the Processing & Logistics and Natural Gas 
Transportation & Logistics segments, respectively, as discussed further below.

Operating costs and expenses. Operating costs and expenses were $348.8 million for the year ended December 31, 2016
compared to $338.3 million for the year ended December 31, 2015, which represents an increase of $10.5 million, or 3%. The
overall increase in operating costs and expenses is primarily driven by increased operating costs and expenses of $20.0
million in the Crude Oil Transportation & Logistics segment, partially offset by decreased operating costs and expenses 
of $10.9 million and $0.7 million in the Natural Gas Transportation & Logistics and Processing & Logistics segments, 
respectively, as discussed further below, as well as a $2.3 million increase in corporate general and administrative costs due to 
increased overhead costs allocated from TD.

Interest expense, net. Interest expense of $40.7 million for the year ended December 31, 2016 was primarily composed of 
interest and fees associated with our revolving credit facility and the 2024 Notes issued on September 1, 2016. Interest expense 
of $15.5 million for the year ended December 31, 2015 was primarily composed of interest and fees associated with our 
revolving credit facility, partially offset by interest income of $0.4 million on the cash balance swept to TD under the Pony 
Express cash management agreement. The increase in interest and fees in 2016 is primarily associated with our revolving credit 
facility due to increased borrowings to fund a portion of our 2015 acquisitions and our recent acquisitions of an additional 
31.3% membership interest in Pony Express effective January 1, 2016 and a 25% membership interest in Rockies Express 
effective May 6, 2016, as well as the higher incremental borrowing rate on the 2024 Notes, the proceeds of which were used to 
repay borrowings under our revolving credit facility.

Unrealized loss on derivative instrument. Unrealized loss on derivative instrument of $1.3 million represents the change in 

fair value of the call option received from TD as part of the acquisition of an additional 31.3% membership interest in Pony 
Express effective January 1, 2016.

Equity in earnings of unconsolidated investment. Equity in earnings of unconsolidated investment of $51.8 million for the 

year ended December 31, 2016 reflects our portion of earnings and the amortization of a negative basis difference of $9.1 
million associated with our acquisition of a 25% membership interest in Rockies Express effective May 6, 2016. The equity in 
earnings for the year ended December 31, 2016 includes recognition of our portion of the $65 million settlement received by 
Rockies Express related to the lawsuit between Interior and Rockies Express as discussed in Note 18 – Legal and 
Environmental Matters.

Other income, net. Other income, net typically includes rental income and income earned from certain customers related to 

the capital costs we incurred to connect these customers to our system. Other income for the year ended December 31, 2016
was $1.7 million compared to $2.4 million for the year ended December 31, 2015. The decrease in other income was driven by 
lower income related to reimbursable projects at TIGT due to a contract termination during the year ended December 31, 2016.

Net (income) loss attributable to noncontrolling interests. Net income attributable to noncontrolling interests of $4.4
million for the year ended December 31, 2016 primarily reflects the net income allocated to TD's 2% noncontrolling interest in 
Pony Express. Net income attributable to noncontrolling interest of $24.3 million for the year ended December 31, 2015
primarily reflects the net income allocated to TD's 66.7% noncontrolling interest in Pony Express for the period from January 
1, 2015 to February 28, 2015 and TD's 33.3% noncontrolling interest for the period from March 1, 2015 to December 31, 2015.

Year Ended December 31, 2015 Compared to the Year Ended December 31, 2014

Revenues. Total revenues were $536.2 million for the year ended December 31, 2015, compared to $371.6 million for the 

year ended December 31, 2014, which represents an increase of $164.6 million, or 44%, in total revenues. The
overall increase in revenue was primarily driven by increased revenues of $275.9 million in the Crude Oil Transportation & 
Logistics segment, partially offset by decreases in revenues of $102.7 million and $8.4 million in the Processing & Logistics 
and Natural Gas Transportation & Logistics segments, respectively, as discussed further below.

Operating costs and expenses. Operating costs and expenses were $338.3 million for the year ended December 31, 2015
compared to $318.1 million for the year ended December 31, 2014, which represents an increase of $20.1 million, or 6%. The
overall increase in operating costs and expenses was primarily driven by increased operating costs and expenses of $120.0
million in the Crude Oil Transportation & Logistics segment, partially offset by decreases in operating costs and expenses of 
$86.8 million and $9.3 million in the Processing & Logistics and Natural Gas Transportation & Logistics segments, 
respectively, as discussed further below.

70

Interest expense, net. Interest expense of $15.5 million for the year ended December 31, 2015 was primarily composed of 
interest and fees associated with TEP's revolving credit facility, partially offset by interest income of $0.4 million on the cash 
balance swept to TD under the Pony Express cash management agreement. Interest expense of $7.3 million for the year ended 
December 31, 2014 was primarily composed of interest and fees associated with TEP's revolving credit facility, partially offset
by interest income of $1.5 million on the cash balance swept to TD under the Pony Express cash management agreement. The
increase in interest and fees associated with TEP's revolving credit facility in 2015 was driven by increased borrowings 
throughout 2014 and 2015 to fund the acquisitions of Trailblazer and a 66.7% membership interest in Pony Express.

Gain on remeasurement of unconsolidated investment. Gain on remeasurement of unconsolidated investment of $9.4
million for the year ended December 31, 2014 was related to the remeasurement to fair value of our original 50% equity 
investment in Grasslands Water Services I, LLC ("GWSI") in connection with TEP's consolidation of the Water Solutions 
business on May 13, 2014.

Equity in earnings of unconsolidated investment. Equity in earnings of unconsolidated investment of $0.7 million for
the year ended December 31, 2014 was related to our investment in GWSI prior to TEP's consolidation of the Water Solutions 
business on May 13, 2014.

Other income, net. Other income, net typically includes rental income, income earned from certain customers related to the 
capital costs we incurred to connect these customers to our system, and the allowance for funds used during construction at our 
regulated entities. Other income for the year ended December 31, 2015 was $2.4 million compared to $3.1 million for the year
ended December 31, 2014.

Net (income) loss attributable to noncontrolling interests. Net income attributable to noncontrolling interests of $24.3
million for the year ended December 31, 2015 primarily reflects the net income allocated to TD's 66.7% noncontrolling interest 
in Pony Express for the period from January 1, 2015 to February 28, 2015 and TD's 33.3% noncontrolling interest for the 
period from March 1, 2015 to December 31, 2015. Net loss attributable to noncontrolling interest of $11.4 million for the year
ended December 31, 2014 primarily reflects TD's 66.7% noncontrolling interest in Pony Express.

Year Ended December 31, 2016 Compared to the Year Ended December 31, 2015

Revenues. Crude Oil Transportation & Logistics segment revenues were $380.5 million for the year ended December 31, 

2016, compared to $304.2 million for the year ended December 31, 2015, which represents an increase of $76.3 million, or 
25%, in segment revenues due to a $74.5 million increase in crude oil transportation services revenue and a $3.8 million
increase in sales of natural gas, NGLs, and crude oil primarily due to increased volumes sold during the year ended December 
31, 2016. The increase in crude oil transportation services was primarily driven by a $42.6 million increase in revenue from a 
full period of operations on the lateral in Northeast Colorado, which began commercial operations during the second quarter of 
2015, a $19.6 million increase related to the activation of one of our joint tariffs in the second quarter of 2015, and lower 
revenue of $9.8 million during the year ended December 31, 2015 due to a force majeure at one of our joint tariff partners.

Operating costs and expenses. Operating costs and expenses in the Crude Oil Transportation & Logistics segment were 

$164.7 million for the year ended December 31, 2016 compared to $144.8 million for the year ended December 31, 2015,
which represents an increase of $20.0 million, or 14%. The overall increase in operating costs and expenses was primarily 
driven by an $8.2 million increase in cost of transportation services, primarily due to $4.2 million associated with drag-
reduction agents and higher electrical costs at pump stations associated with increased transportation volumes, and increases of 
$4.3 million, $4.2 million, and $2.8 million in operations and maintenance costs, depreciation and amortization, and taxes, 
other than income taxes, respectively, all primarily driven by the costs associated with a full period of operations on the lateral 
in Northeast Colorado.

Year Ended December 31, 2015 Compared to the Year Ended December 31, 2014

Revenues. Crude Oil Transportation & Logistics segment revenues were $304.2 million for the year ended December 31, 

2015 compared to $28.3 million for the year ended December 31, 2014. Revenue for the year ended December 31, 2015
represents a full year of operations at Pony Express, including approximately $62.6 million of revenue from a partial year of 
operations on the lateral in Northeast Colorado, which began commercial operations during the second quarter of 2015, and 
approximately $32.8 million related to the activation of one of our joint tariffs in the second quarter of 2015. Revenue for the 
year ended December 31, 2014 represents a partial year of operations at the mainline portion of the Pony Express System, 
which began commercial operations in October 2014.

Operating costs and expenses. Operating costs and expenses in the Crude Oil Transportation & Logistics segment 

were $144.8 million for the year ended December 31, 2015 compared to $24.7 million for the year ended December 31, 2014.
Operating costs and expenses for the year ended December 31, 2015 represents a full year of operations at Pony Express as 
well as a partial year of operations on the lateral in Northeast Colorado, which began commercial operations during the second 
quarter of 2015. Operating costs and expenses for the year ended December 31, 2014 represents a partial year of operations at 
the mainline portion of the Pony Express System, which began commercial operations in October 2014.

Year Ended December 31, 2016 Compared to the Year Ended December 31, 2015

Revenues. Natural Gas Transportation & Logistics segment revenues were $128.9 million for the year ended December 31, 

2016, compared to $131.7 million for the year ended December 31, 2015, which represents a decrease of $2.8 million, or 2%,
in segment revenues driven by a $3.1 million decrease in sales of natural gas, NGLs, and crude oil as a result of lower volumes 
of natural gas sold. The decrease in sales of natural gas, NGLs, and crude oil was partially offset by a $0.3 million increase in 
natural gas transportation services primarily driven by a $2.3 million increase at TIGT, partially offset by a $1.9 million 
decrease at Trailblazer due to warmer weather in the first quarter of 2016, resulting in lower volumes transported during the 
year ended December 31, 2016. The increase in natural gas transportation services revenue at TIGT was primarily driven by 
increased tariff rates, partially offset by a change in the fuel recovery structure, beginning May 1, 2016 as a result of the rate 
case settlement discussed in Note 17 – Regulatory Matters.

Operating costs and expenses. Operating costs and expenses in the Natural Gas Transportation & Logistics segment were 
$79.0 million for the year ended December 31, 2016 compared to $89.9 million for the year ended December 31, 2015, which 
represents a decrease of $10.9 million, or 12%. The overall decrease in operating costs and expenses was primarily driven by 
a $5.9 million decrease in cost of transportation services due to lower costs associated with fuel reimbursements as a result of 
the change in the fuel recovery structure discussed above, a $2.5 million decrease in cost of sales due to lower volumes of 
natural gas sold, and a $2.0 million decrease in depreciation and amortization due to lower depreciation rates as of May 1, 2016 
as a result of the TIGT rate case settlement.

Year Ended December 31, 2015 Compared to the Year Ended December 31, 2014

Revenues. Natural Gas Transportation & Logistics segment revenues were $131.7 million for the year ended December 31, 

2015, compared to $140.1 million for the year ended December 31, 2014, which represents an $8.4 million, or 6%, decrease in
segment revenues primarily due to a $6.7 million decrease in natural gas transportation services revenue driven by lower fuel 
reimbursements as a result of decreased prices and a $1.5 million decrease in revenue from the sales of natural gas, NGLs, and 
crude oil as a result of a 46% decrease in natural gas prices, partially offset by favorable hedge settlements and increased 
volumes sold.

Operating costs and expenses. Operating costs and expenses in the Natural Gas Transportation & Logistics segment were 
$89.9 million for the year ended December 31, 2015 compared to $99.2 million for the year ended December 31, 2014, which 
represents a decrease of $9.3 million, or 9%. The overall decrease in operating costs and expenses was primarily driven by a 
$7.2 million decrease in the cost of transportation services, due to lower fuel reimbursements as a result of decreased prices, a 
$1.3 million decrease in taxes, other than income taxes, due to revised property tax estimates as a result of successful appeals 
with state taxing authorities on the assessed value of property, a $0.9 million decrease in depreciation and amortization driven 
by a change in rates at Trailblazer as a result of the rate case settlement in 2014, and a $0.7 million decrease in cost of sales, due 
to a 51% decrease in natural gas prices, partially offset by increased volumes sold.

Year Ended December 31, 2016 Compared to the Year Ended December 31, 2015

Revenues. Processing & Logistics segment revenues were $101.4 million for the year ended December 31, 2016, compared 
to $105.7 million for the year ended December 31, 2015, which represents a $4.3 million, or 4%, decrease in segment revenues. 
The decrease in segment revenues was primarily due to a $3.4 million decrease in the sales of natural gas, NGLs, and crude oil 
driven by lower NGL and natural gas sales due to lower volumes processed, partially offset by increased NGL prices, and a 
$0.9 million decrease in processing and other revenues driven by lower processing fees of $4.9 million due to decreased 
volumes processed, partially offset by a $4.0 million increase in revenue primarily attributable to the recently acquired Western
and West Texas assets.

Operating costs and expenses. Operating costs and expenses in the Processing & Logistics segment were $100.3 million
for the year ended December 31, 2016 compared to $101.0 million for the year ended December 31, 2015, which represents a
decrease of $0.7 million, or 1%. The decrease in operating costs and expenses was driven by (i) a decrease of $2.9 million in 
loss on disposal of assets as a result of the $1.8 million loss on assets destroyed by fire as a result of a lightning strike during 
the year ended December 31, 2016, compared to a $4.8 million non-cash loss recognized on the sale of compressor and other 
assets in 2015; (ii) a decrease of $1.0 million in cost of sales, driven by decreased NGL volumes processed as discussed above; 
(iii) a $0.8 million decrease in depreciation and amortization driven by an intangible asset becoming fully amortized as of 
December 31, 2015, partially offset by increased depreciation related to the new NGL transportation line; and (iv) a $0.7
million decrease in operations and maintenance costs due to less downtime for plant maintenance activities during the year
ended December 31, 2016 compared to the year ended December 31, 2015, partially offset by higher costs associated with the 
recently acquired Western and West Texas assets. These decreases were partially offset by (i) a $2.5 million increase in cost of 
transportation services due to costs associated with Western, which was acquired on December 16, 2015; (ii) a $1.8 million
increase in general and administrative costs due to increased costs allocated to Water Solutions as a result of increased 
operating income related to our acquisitions of Western and West Texas; and (iii) a $0.6 million increase in taxes, other than 
income taxes, due to higher property tax estimates for 2016 as a result of the Western acquisition.

74

Year Ended December 31, 2015 Compared to the Year Ended December 31, 2014

Revenues. Processing & Logistics segment revenues were $105.7 million for the year ended December 31, 2015, compared 

to $208.4 million for the year ended December 31, 2014, which represents a $102.7 million, or 49%, decrease in segment 
revenues. The decrease in segment revenues was primarily due to a $101.4 million decrease in the sales of natural gas, NGLs, 
and crude oil driven by a 58% decrease in NGL prices and lower volumes processed, and a $1.3 million decrease in processing 
and other revenues driven by lower processing fees at TMID due to decreased volumes processed under a large, fee-based 
contract, partially offset by increased revenue at Water Solutions, including water transportation services and revenue 
associated with a contract to construct a water pipeline for a customer during the year ended December 31, 2015. Prior to its 
consolidation in May 2014, TEP's investment in Water Solutions was accounted for under the equity method of accounting and 
as a result TEP recognized no revenues from Water Solutions for the period from January 1, 2014 to May 13, 2014.

Operating costs and expenses. Operating costs and expenses in the Processing & Logistics segment were $101.0 million
for the year ended December 31, 2015 compared to $187.8 million for the year ended December 31, 2014, which represents a
decrease of $86.8 million, or 46%. The decrease in operating costs and expenses was driven by a decrease of $95.8 million in
cost of sales, primarily due to decreased NGL prices and volumes processed as discussed above. The decrease in cost of sales 
was partially offset by $4.8 million of non-cash losses recognized on the sale of compressor and other assets in 2015, and 
overall increases in the cost of transportation services, operations and maintenance costs, depreciation and amortization, and 
general and administrative costs, all primarily driven by the costs associated with Water Solutions, which was consolidated in 
May 2014.

Liquidity and Capital Resources Overview

Our primary sources of liquidity for the year ended December 31, 2016 were proceeds from the issuance of long-term debt 

as discussed further below, borrowings under our revolving credit facility, cash generated from operations, and proceeds from 
the issuance of common units. We expect our sources of liquidity in the future to include:

•

•

•

cash generated from our operations;

borrowing capacity available under our revolving credit facility; and

future issuances of additional partnership units and/or debt securities.

We believe that cash on hand, cash generated from operations and availability under our revolving credit facility will be 

adequate to meet our operating needs, our planned short-term maintenance capital and debt service requirements and our 
planned cash distributions to unitholders. We believe that future internal growth projects or potential acquisitions will be funded 
primarily through a combination of borrowings under our revolving credit facility and issuances of debt and/or equity 
securities.

Our total liquidity as of December 31, 2016 and 2015 was as follows:

(1) Effective January 4, 2016, in connection with the acquisition of an additional 31.3% membership interest in Pony 

Express, TEP exercised the committed accordion feature to increase the total capacity of the revolving credit facility to 
$1.5 billion. In connection with the acquisition of a 25% membership interest in Rockies Express, TEP amended the 
revolving credit facility to increase the total capacity to $1.75 billion, which increase became effective May 6, 2016.

(2) As of February 3, 2017, our outstanding borrowings under the revolving credit facility were approximately $1.130

billion.

Revolving Credit Facility

We have a senior secured revolving credit facility with Barclays Bank PLC, as administrative agent, and a syndicate of 
lenders (as amended, the "Credit Agreement") which will mature on May 17, 2018. As of December 31, 2016, the revolving 
credit facility has a total capacity of $1.75 billion and includes a $75 million sublimit for letters of credit and a $60 million
sublimit for swing line loans. The unused portion of the revolving credit facility is subject to a commitment fee, which ranges 
from 0.300% to 0.500%, based on our total leverage ratio. As of December 31, 2016, the weighted average interest rate on 
outstanding borrowings was 2.48%. During the year ended December 31, 2016, our weighted average effective interest rate, 
including the interest on outstanding borrowings, commitment fees, and amortization of deferred financing costs, was 2.75%.

The revolving credit facility contains various covenants and restrictive provisions that, among other things, limit or restrict 

our ability (as well as the ability of our restricted subsidiaries) to incur or guarantee additional debt, incur certain liens on 
assets, dispose of assets, make certain distributions (including distributions from available cash, if a default or event of default 
under the credit agreement then exists or would result from making such a distribution), change the nature of our business, 
engage in certain mergers or make certain investments and acquisitions, enter into non-arms-length transactions with affiliates
and designate certain subsidiaries as "Unrestricted Subsidiaries." In addition, we are required to maintain a consolidated 
leverage ratio of not more than 4.75 to 1.00 (which will be increased to 5.25 to 1.00 for certain measurement periods following 
the consummation of certain acquisitions) and a consolidated interest coverage ratio of not less than 2.50 to 1.00. As of 
December 31, 2016, we are in compliance with the covenants required under the revolving credit facility.

Senior Unsecured Notes

On September 1, 2016, TEP and Tallgrass Energy Finance Corp. (the "Co-Issuer" and together with TEP, the "Issuers"), the 

Guarantors named therein and U.S. Bank, National Association, as trustee, entered into an Indenture dated September 1, 2016 
(the "Indenture"), pursuant to which the Issuers issued $400 million in aggregate principal amount of the Issuers' 5.50% senior 
notes due 2024 (the "2024 Notes"). TEP used the net proceeds of the issuance to repay outstanding borrowings under its 
existing revolving credit facility.

The 2024 Notes are general unsecured senior obligations of the Issuers. The 2024 Notes are unconditionally guaranteed 
jointly and severally on a senior unsecured basis by TEP's existing direct and indirect wholly owned subsidiaries (other than the 
Co-Issuer) and certain of TEP's future subsidiaries (the "Guarantors"). The 2024 Notes rank equal in right of payment with all 
existing and future senior indebtedness of the Issuers, and senior in right of payment to any future subordinated indebtedness of 
the Issuers. The 2024 Notes will mature on September 15, 2024 and interest on the 2024 Notes is payable in cash semi-annually 
in arrears on each March 15 and September 15, commencing March 15, 2017. TEP may redeem the 2024 Notes prior to their 
scheduled maturity at the applicable redemption price set forth in the Indenture, plus accrued and unpaid interest.

The Indenture contains covenants that, among other things, limit TEP's ability and the ability of its restricted subsidiaries 

to: (i) incur, assume or guarantee additional indebtedness or issue preferred units; (ii) create liens to secure indebtedness; 
(iii) pay distributions on equity interests, repurchase equity securities or redeem subordinated securities; (iv) make investments; 
(v) restrict distributions, loans or other asset transfers from TEP's restricted subsidiaries; (vi) consolidate with or merge with or 
into, or sell substantially all of TEP's properties to, another person; (vii) sell or otherwise dispose of assets, including equity 
interests in subsidiaries; and (viii) enter into transactions with affiliates. As of December 31, 2016, we are in compliance with 
the covenants required under the 2024 Notes.

Equity Distribution Agreements

On October 31, 2014, we entered into an equity distribution agreement pursuant to which we may sell from time to time 

through a group of managers, as our sales agents, common units representing limited partner interests having an aggregate 
offering price of up to $200 million. On May 13, 2015, the amount was subsequently amended to $100.2 million in order to 
account for follow-on equity offerings under our S-3 shelf registration statement. On May 17, 2016, we entered into a new 
equity distribution agreement allowing for the sale of common units with an aggregate offering price of up to $657.5 million.
Sales of common units, if any, will be made by means of ordinary brokers' transactions, to or through a market maker or 
directly on or through an electronic communication network, a "dark pool" or any similar market venue, or as otherwise agreed 
by the Partnership and one or more of the managers. We intend to use the net cash proceeds from any sale of the units for 
general partnership purposes, which may include, among other things, the Partnership's exercise of the call option with respect 
to the 6,518,000 common units issued to TD in connection with the Partnership's acquisition of an additional 31.3% of Pony 
Express in January 2016, repayment or refinancing of debt, funding for acquisitions, capital expenditures and additions to 
working capital.

76

During the year ended December 31, 2016, we issued and sold 7,696,708 common units with a weighted average sales 
price of $44.46 per unit under our equity distribution agreements for net cash proceeds of approximately $337.7 million (net of 
approximately $4.5 million in commissions and professional service expenses). During the period from January 1, 2017 to 
February 15, 2017, we issued and sold an additional 2,075,546 common units with a weighted average sales price of $48.19 per 
unit under our equity distribution agreements for net cash proceeds of approximately $99.0 million (net of approximately $1.0
million in commissions and professional service expenses). We used the net cash proceeds for general partnership purposes as 
described above. 

During the year ended December 31, 2015, we issued and sold 65,744 common units with a weighted average sales price 

of $45.58 per unit under our equity distribution agreement for net cash proceeds of approximately $3.0 million (net of 
approximately $30,000 in commissions and professional service expenses). We used the net cash proceeds for general 
partnership purposes as described above. 

During the year ended December 31, 2014, we issued and sold 28,625 common units with a weighted average sales price 

of $44.20 per unit under our equity distribution agreement for net cash proceeds of approximately $1.1 million (net of 
approximately $215,000 in commissions and professional service expenses). We used the net cash proceeds for general 
partnership purposes as described above. 

Private Placement

On April 28, 2016, we issued an aggregate of 2,416,987 common units for net cash proceeds of $90.0 million in a private 

placement transaction to certain funds managed by Tortoise Capital Advisors, L.L.C. The units were subsequently registered 
pursuant to our Form S-3/A (File No. 333-210976) filed with the SEC on May 6, 2016, which became effective May 17, 2016.

Working Capital

Working capital is the amount by which current assets exceed current liabilities. While various other factors may impact 
our working capital requirements from period to period, our working capital requirements have typically been, and we expect 
will continue to be, driven by changes in accounts receivable, accounts payable and deferred revenue. We manage our working 
capital needs through borrowings and repayments of borrowings under our revolving credit facility. Factors impacting changes 
in accounts receivable and accounts payable could include the timing of collections from customers, payments to suppliers, and 
the level of spending for capital expenditures. Changes in the market prices of energy commodities, primarily NGLs, that we 
buy and sell in the normal course of business can also impact the timing of changes in accounts receivable and accounts 
payable. Factors impacting deferred revenue include the volume of crude oil transported, the amount of deficiency payments 
received, and the volume of prior deficiencies utilized during the period.

As of December 31, 2016, we had a working capital deficit of $38.3 million compared to a working capital deficit of $11.7

million at December 31, 2015, which represents a decrease in working capital of $26.6 million. The overall decrease in 
working capital was primarily attributable to changes in the following components:

•

•

•

an increase in deferred revenue of $34.2 million primarily from deficiency payments collected by Pony Express;

an increase in accrued liabilities of $6.5 million primarily due to $7.3 million of interest accrued at December 31, 2016 
associated with the 2024 Notes issued on September 1, 2016, partially offset by a decrease in environmental accruals 
due to remediation spending during the year ended December 31, 2016; and

an increase in accrued taxes of $2.5 million as a result of higher tax assessments for 2016 due to the Pony Express 
lateral in Northeast Colorado and the recently acquired Western assets, partially offset by reduced assessments at 
certain assets as a result of successful appeals with state taxing authorities on the assessed value of property.

These working capital decreases were partially offset by:

•

•

an increase of $11.0 million in derivative assets at fair value as a result of the call option derivative asset remaining as 
of December 31, 2016; and

an increase of $4.0 million in prepayments and other current assets as a result of prepayment of insurance policies by 
TEP, which had previously been paid by TD and reimbursed by TEP as they were incurred. 

A material adverse change in operations, available financing under our revolving credit facility, or available financing from 

the equity or debt capital markets could impact our ability to fund our requirements for liquidity and capital resources in the 
future.

ended December 31, 2016 and 2015, respectively. The increase in net cash flows provided by operating activities of $120.2
million was primarily driven by the increase in operating results as discussed above, $51.8 million of distributions received 
from Rockies Express, and a net increase in cash inflows from changes in working capital, primarily driven by a $17.6 million
increase in net cash inflows from accounts receivable due to collection of receivables during the year ended December 31, 2016 
associated primarily with an increase in incremental barrels shipped at Pony Express, and a $13.2 million increase in deferred 
revenue associated primarily with deficiency payments collected by Pony Express during the year ended December 31, 2016.

Investing Activities. Cash flows used in investing activities were $581.7 million for the year ended December 31, 2016.

Investing cash outflows for the year ended December 31, 2016 were primarily driven by:

•

•

•

•

cash outflows of $436.0 million for the acquisition of a 25% membership interest in Rockies Express on May 6, 2016;

capital expenditures of $70.7 million, primarily due to post in-service spending on Pony Express System projects and 
the Pipeline Integrity Management Program at Trailblazer;

cash outflows of $49.1 million for a portion of the acquisition of an additional 31.3% membership interest in Pony 
Express on January 1, 2016, the remainder of which is classified as a financing activity as discussed below; and

contributions to Rockies Express in the amount of $50.0 million.

These cash outflows were partially offset by $24.1 million of distributions from Rockies Express in excess of cumulative 

earnings recognized.

Cash flows used in investing activities were $845.3 million for the year ended December 31, 2015. Investing cash outflows 

for the year ended December 31, 2015 were primarily driven by:

•

•

the cash outflow of $700.0 million for the acquisition of an additional 33.3% membership interest in Pony Express, 
which allowed TD to continue funding the pipeline construction at Pony Express; and

the cash outflow of $75.0 million for the acquisition of Western, and capital expenditures of $65.4 million, primarily 
due to construction of the Pony Express System, including the lateral in Northeast Colorado.

Financing Activities. Cash flows provided by financing activities were $172.5 million for the year ended December 31, 

2016. Financing cash inflows for the year ended December 31, 2016 were primarily driven by:

•

•

•

•

•

proceeds from the issuance of $400.0 million in aggregate principal amount of 5.50% Senior Notes due 2024;

the issuance of 7,696,708 common units under the Equity Distribution Agreements for net cash proceeds of $337.7
million;

net borrowings under the revolving credit facility of $262.0 million;

the issuance of 2,416,987 common units representing limited partnership interests in a private placement transaction 
for net cash proceeds of $90.0 million; and

contributions from TD of $17.9 million, which consisted of contributions from TD to TEP in order to indemnify TEP
for any out of pocket costs incurred between April 1, 2014 and April 1, 2017 related to repairing or remediating the 
Trailblazer Pipeline, as discussed further in Note 18 – Legal and Environmental Matters.

78

 
These financing cash inflows were partially offset by cash outflows of:

•

•

•

$425.9 million for the portion of the acquisition of an additional 31.3% membership interest in Pony Express which 
exceeds the cumulative capital spending on the underlying assets acquired;

distributions to unitholders of $292.8 million; and

$204.6 million for the partial exercise of the call option granted by TD covering 4,814,906 common units.

Cash flows provided by financing activities were $556.7 million for the year ended December 31, 2015. Financing cash 

inflows for the year ended December 31, 2015 were primarily driven by:

•

•

net cash proceeds of $554.1 million from the issuance of 11,200,000 common units in a public offering and 65,744
common units issued under the Equity Distribution Agreements during 2015; and

net borrowings under the revolving credit facility of $194.0 million.

These financing cash inflows were partially offset by cash outflows of:

•

•

distributions to unitholders of $161.8 million; and

distributions to noncontrolling interests of $25.1 million, primarily driven by distributions to TD from Pony Express.

Year Ended December 31, 2015 Compared to the Year Ended December 31, 2014

Operating Activities. Cash flows provided by operating activities were $289.3 million and $79.4 million for the years

ended December 31, 2015 and 2014, respectively. The increase in net cash flows provided by operating activities of $209.9
million was primarily driven by the increase in operating results and a net increase in cash inflows from changes in working 
capital, primarily driven by a $31.6 million decrease in net cash outflows from accounts payable and accrued liabilities due to 
increased property tax accruals and related party payables and a $14.0 million increase in net cash inflows from deficiency 
payments received by Pony Express, partially offset by a decrease in net cash inflows of $15.3 million from accounts 
receivable, due to increased receivables at Pony Express.

Investing Activities. Cash flows used in investing activities were $845.3 million for the year ended December 31, 2015.
Investing cash outflows for the year ended December 31, 2015 were primarily driven by the acquisitions of Western and an 
additional 33.3% membership interest in Pony Express, as discussed above.

Cash flows used in investing activities were $1.1 billion for the year ended December 31, 2014. Investing cash outflows 

for the year ended December 31, 2014 were primarily driven by:

•

•

•

capital expenditures of $665.7 million, primarily due to construction at Pony Express, including the lateral in 
Northeast Colorado, as well as the capacity expansion projects at TMID and other expansion projects at Trailblazer;

cash outflows of $270.0 million associated with the related party loan to TD under the Pony Express cash management 
agreement; and

cash outflows of $150.0 million, $27.0 million, and $7.6 million for the acquisitions of Trailblazer, Pony Express, and 
Water Solutions, respectively.

These cash outflows were partially offset by cash inflows of $20.0 million from the return of funds deposited with Shell in 

support of the crude oil resale obligation of Pony Express.

Financing Activities. Cash flows provided by financing activities were $556.7 million for the year ended December 31, 
2015. Financing cash inflows for the year ended December 31, 2015 were primarily driven by proceeds from the issuance of 
common units and net borrowings under the revolving credit facility, partially offset by distributions to unitholders and 
noncontrolling interests, as discussed above. 

Cash flows provided by financing activities were $1.0 billion for the year ended December 31, 2014. Financing cash 

inflows for the year ended December 31, 2014 were primarily driven by: 

•

•

•

•

net borrowings under the revolving credit facility of $424.0 million;

net proceeds of $320.4 million from the issuance of 8,050,000 common units in a public offering and 28,625 common 
units issued under the Equity Distribution Agreements during 2014;

net contributions from Predecessor Entities of $312.1 million; and

a contribution from TD of $27.5 million representing the difference between the carrying amount of the Replacement 
Gas Facilities, as defined in Note 5 – Related Party Transactions, and the proceeds received from TD.

These cash inflows were partially offset by distributions to unitholders of $68.1 million.

79

Distributions

We do not have a legal obligation to pay distributions except as provided in our partnership agreement. A distribution 

of $0.815 per unit, or $88.2 million in the aggregate, for the three months ended December 31, 2016 was declared on 
January 24, 2017 and was paid on February 14, 2017 to unitholders of record on February 3, 2017. As of February 15, 2017, we 
had a total of 72,973,429 common and general partner units outstanding, which equates to an aggregate minimum quarterly 
distribution of approximately $21.0 million per quarter and approximately $83.9 million per year. We intend to continue to pay 
quarterly distributions at or above the amount of the minimum quarterly distribution, which is $0.2875 per unit.

Capital Requirements

The midstream energy business can be capital-intensive, requiring significant investment to maintain and upgrade existing 

operations. Our capital requirements have consisted primarily of, and we anticipate will continue to consist of, the following:

• maintenance capital expenditures, which are cash expenditures incurred (including expenditures for the construction or 
development of new capital assets) that we expect to maintain our long-term operating income or operating capacity.
These expenditures typically include certain system integrity, compliance and safety improvements; and

•

expansion capital expenditures, which are cash expenditures to increase our operating income or operating capacity 
over the long-term. Expansion capital expenditures include acquisitions or capital improvements (such as additions to 
or improvements on the capital assets owned, or acquisition or construction of new capital assets).

We expect to incur approximately $55 million for capital expenditures in 2017, of which approximately $39 million is 
expected for expansion projects and approximately $16 million, net of anticipated reimbursements from affiliates, is expected 
for maintenance capital expenditures.

The determination of capital expenditures as maintenance or expansion is made at the individual asset level during our 

budgeting process and as we approve, execute, and monitor our capital spending. The following table summarizes the 
maintenance and expansion capital expenditures incurred at our consolidated entities:

Year Ended December 31,

2016

Capital expenditures incurred represent capital expenditures paid and accrued during the period. Capital expenditures are 
presented net of noncontrolling interest, and contributions and reimbursements received. The decrease in maintenance capital 
expenditures to $11.3 million for the year ended December 31, 2016 from $12.1 million for the year ended December 31, 2015
is primarily driven by decreased maintenance capital expenditures in the Processing & Logistics segment. Maintenance capital 
expenditures on our assets occur on a regular schedule, but most major maintenance projects are not required every year so the 
level of maintenance capital expenditures naturally varies from year to year and from quarter to quarter. The increase in
expansion capital expenditures to $30.6 million for the year ended December 31, 2016 from $16.9 million for the year ended 
December 31, 2015 is primarily driven by increased expansion capital expenditures in the Crude Oil Transportation & Logistics 
segment due to post in-service spending on Pony Express System projects. Expansion capital expenditures of $16.9 million for 
the year ended December 31, 2015 consisted primarily of spending on the NGL pipeline in Northeast Colorado. During the year 
ended December 31, 2015, substantially all of the expansion capital expenditures related to Pony Express System projects were 
funded by TD as discussed in Note 4 – Acquisitions and Note 12 – Partnership Equity and Distributions.

The increase in maintenance capital expenditures to $12.1 million for the year ended December 31, 2015 from $9.9

million for the year ended December 31, 2014 is primarily driven by increased maintenance capital expenditures in the Natural 
Gas Transportation & Logistics and Processing & Logistics segments. Maintenance capital expenditures on our assets occur on 
a regular schedule, but most major maintenance projects are not required every year so the level of maintenance capital 
expenditures naturally varies from year to year and from quarter to quarter. The decrease in expansion capital expenditures to 
$16.9 million for the year ended December 31, 2015 from $193.7 million for the year ended December 31, 2014 is primarily 
driven by the significant spending on the Pony Express System prior to commencement of commercial operations in October 
2014. Expansion capital expenditures of $16.9 million for the year ended December 31, 2015 consisted primarily of spending 
on the NGL pipeline in Northeast Colorado prior to commencement of commercial service in the fourth quarter of 2015.

80

 
In addition, we invested cash in unconsolidated affiliates of $50.0 million during the year ended December 31, 2016 and

$2.0 million during the year ended December 31, 2014 to fund our share of capital projects. There were no investments in 
unconsolidated affiliates during the year ended December 31, 2015. We expect to make contributions to unconsolidated 
affiliates of approximately $24 million to fund our 25% portion of capital projects at Rockies Express during the year ending 
December 31, 2017.

We intend to make cash distributions to our unitholders and our general partner. Due to our cash distribution policy, we 
expect that we will distribute to our unitholders most of the cash generated by our operations. We expect to fund future capital 
expenditures with funds generated from our operations, borrowings under our revolving credit facility, the issuance of 
additional partnership units and/or the issuance of long-term debt. If these sources are not sufficient, we may reduce our 
discretionary spending.

(1) Debt obligations at December 31, 2016 consisted of borrowings under the revolving credit facility and the 2024 Notes. For 
additional information, see Note 11 – Long-term Debt to the Consolidated Financial Statements in Item 8.—Financial 
Statements and Supplementary Data. 

(2)

Interest on debt obligations is estimated using current borrowings and interest rates as of December 31, 2016. For 
additional information, see Note 11 – Long-term Debt to the Consolidated Financial Statements in Item 8.—Financial 
Statements and Supplementary Data.

(3) Operating leases and service contracts consist of leases for crude oil storage as well as office space and equipment. Lease 
obligations include approximately $255.8 million in future minimum lease payments to Terminals related to the Sterling 
Terminal facilities, which we acquired effective January 1, 2017. Lease obligations for the crude oil storage at the Sterling 
and Deeprock Terminals assume renewal for the full 20-year lease term. For additional information, see Note 13 – 
Commitments & Contingent Liabilities to our Consolidated Financial Statements in Item 8.—Financial Statements and 
Supplementary Data in this Form 10-K.

(4) Land site lease and right-of-way contracts consist of payments to landowners, primarily in our Crude Oil Transportation & 
Logistics and Natural Gas Transportation & Logistics segments. For additional information, see Note 13 – Commitments & 
Contingent Liabilities to our Consolidated Financial Statements in Item 8.—Financial Statements and Supplementary Data 
in this Form 10-K.

(5) Other purchase commitments primarily relate to planned non-reimbursable capital expenditures and operating and 

maintenance expenditures. 

On May 17, 2013, in connection with the closing of TEP's IPO, TEP and its general partner entered into the TEP Omnibus 

Agreement, which provides that, among other things, TEP will reimburse TD and its affiliates for all expenses they incur and 
payments they make on TEP's behalf, including the costs of employee and director compensation and benefits as well as the 
cost of the provision of certain centralized corporate functions performed by TD, including legal, accounting, cash 
management, insurance administration and claims processing, risk management, health, safety and environmental, information 
technology and human resources in each case to the extent reasonably allocable to TEP.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Critical Accounting Policies and Estimates

Our significant accounting policies and the anticipated impact of recently issued accounting standards are described in 
Note 2 – Summary of Significant Accounting Policies to the consolidated financial statements included in Item 8 of this Annual
Report. Management's discussion and analysis of financial condition and results of operations are based upon our financial 
statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires 
management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and 
the related disclosure of contingent assets and liabilities. The accounting policies discussed below are considered by 
management to be critical to an understanding of our financial statements as their application places the most significant 
demands on management's judgment. Due to the inherent uncertainties involved with this type of judgment, actual results could 
differ significantly from estimates and may have a material adverse impact on our results of operations, equity or cash flows. 
For additional information concerning our other accounting policies, please read the notes to the financial statements included 
in this report.

Description

Judgments and Uncertainties

Effect if Actual Results Differ from
Assumptions

Using the impairment review methodology 
described herein, we have not recorded any 
impairment charges on long-lived assets during 
the year ended December 31, 2016. If actual 
results are not consistent with our assumptions 
and estimates or our assumptions and estimates 
change due to new information, we may be 
exposed to an impairment charge. A prolonged 
period of lower commodity prices may 
adversely affect our estimate of future operating 
results, which could result in future impairment 
due to the potential impact on our operations 
and cash flows.

We review our long-lived assets for 
impairment whenever events or changes in 
circumstances indicate that the carrying 
amount of an asset may not be recoverable. 
Our impairment analyses require 
management to apply judgment in 
estimating future cash flows as well as 
asset fair values, including forecasting 
useful lives of the assets, assessing the 
probability of different outcomes, including 
anticipated volumes, contract renewals and 
changes in our regulated rates, and 
selecting the discount rate that reflects the 
risk inherent in future cash flows. If the 
carrying value is not recoverable, we assess 
the fair value of long-lived assets using a 
discounted cash flow model and other 
commonly accepted techniques.

Impairment of Long-lived Assets
We periodically evaluate
whether the carrying value
of long-lived assets has
been impaired when
circumstances indicate the
carrying value of those
assets may not be
recoverable. This
evaluation is based on
undiscounted cash flow
projections expected to be
realized over the remaining
useful life of the primary
asset. The carrying amount
is not recoverable if it
exceeds the sum of
undiscounted cash flows
expected to result from the
use and eventual disposition
of the asset. If the carrying
value is not recoverable, the
impairment loss is
measured as the excess of
the asset's carrying value
over its fair value.

82

Description

Judgments and Uncertainties

Effect if Actual Results Differ from
Assumptions

We determine fair value using widely
accepted valuation techniques, primarily
discounted cash flow and market multiple
analyses. These techniques are also used
when assigning the purchase price to
acquired assets and liabilities. These types
of analyses require us to make assumptions
and estimates regarding industry and
economic factors and the profitability of
future business strategies. Our impairment
analyses require management to apply
judgment in estimating future cash flows as
well as asset fair values, including
forecasting useful lives of the assets,
assessing the probability of different
outcomes, including anticipated volumes,
contract renewals and changes in our
regulated rates, and selecting the discount
rate that reflects the risk inherent in future
cash flows. It is our policy to conduct
impairment testing based on our current
business strategy in light of present
industry and economic conditions, as well
as future expectations.

When available, quoted market prices or
prices obtained through external sources
are used to determine a contract's fair
value. For contracts with a delivery
location or duration for which quoted
market prices are not available, fair value is
determined based on pricing models
developed primarily from historical
information and the expected relationship
with quoted market prices.

Estimating the fair value of each award, the
number of awards that will ultimately vest,
and the forfeiture rate requires management
to apply judgment to estimate the tenure of
our employees and the achievement of
certain performance targets over the
performance period.

We primarily use a discounted cash flow
analysis, supplemented by a market approach
analysis, to perform the assessment. Key
assumptions in the analysis include the use of
an appropriate discount rate, terminal year
multiples, and estimated future cash flows
including an estimate of operating and general
and administrative costs. In estimating cash
flows, we incorporate current market
information, as well as historical and other
factors, into our forecasted commodity prices. If
our assumptions are not appropriate, or future
events indicate that our goodwill is impaired,
our net income would be impacted by the
amount by which the carrying value exceeds the
fair value of the reporting unit, to the extent of
the balance of goodwill. A prolonged period of
lower commodity prices may adversely affect
our estimate of future operating results, which
could result in future goodwill impairment for
reporting units due to the potential impact on
our operations and cash flows. We completed
our impairment testing of goodwill in the third
quarter of 2016 using the methodology
described herein, and determined there was no
impairment.

If our estimates of fair value are inaccurate, we
may be exposed to losses or gains that could be
material. See Item 7A.—Quantitative and
Qualitative Disclosures About Market Risk for
details regarding the impact of potential
changes in the crude oil and natural gas forward
price curves on our derivative instruments at
December 31, 2016.

If actual results are not consistent with our 
assumptions and judgments or our assumptions 
and estimates change due to new information, 
we may experience material changes in 
compensation expense.

Impairment of Goodwill
We evaluate goodwill for
impairment annually in the
third quarter, and whenever
events or changes in
circumstances indicate it is
more likely than not that the
fair value of a reporting
unit is less than its carrying
amount.

Risk Management Activities
Derivative assets and
liabilities are recorded on
our consolidated balance
sheets at their estimated fair
value as of each reporting
date. Changes in the fair
value of derivative
contracts are recognized in
earnings in the period in
which the change occurs.

Equity-Based Compensation
Equity-based compensation
grants are measured at their
grant date fair value and
related compensation cost is
recognized over the vesting
period of the grant.
Compensation cost for
awards with graded vesting
provisions is recognized on
a straight-line basis over
the requisite service period
of each separately vesting
portion of the award.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Commodity Price Risk

As of December 31, 2016, approximately 99% of our reserved processing capacity was subject to firm or volumetric fee 

contracts, with the majority of fee revenue based on the volumes actually processed. The remaining 1% was subject to 
commodity sensitive contracts such as percent of proceeds or keep whole processing contracts. The profitability of our 
commodity sensitive processing contracts that include keep whole or percent of proceeds components is affected by volatility 
in prevailing NGL and natural gas prices. We do not currently hedge the commodity exposure in our commodity sensitive 
contracts in our Processing & Logistics segment and we do not expect to in the foreseeable future. Starting in the second half of 
2014, the prices of crude oil, natural gas, and NGLs became extremely volatile and declined significantly. Downward pressure 
and volatility on commodity prices continued in 2015 before recovering somewhat in 2016. These declines directly and 
indirectly resulted in lower realizations and processing volumes on our percent of proceeds and keep whole processing 
contracts. Our Processing & Logistics segment comprised approximately 4%, 9% and 30% of our Adjusted EBITDA for the 
years ended December 31, 2016, 2015 and 2014, respectively.

The following table summarizes the percentage of our Adjusted EBITDA at each reportable segment by contract type for

Historically, we have had a limited amount of direct commodity price exposure related to natural gas collected for 
electrical compression costs and lost and unaccounted for gas on the TIGT System. Accordingly, we have historically entered 
into derivative contracts with third parties for a substantial majority of the natural gas we expected to collect for the purpose of 
hedging our commodity price exposures. In 2016, we also entered into long natural gas swaps covering a portion of the natural 
gas that TMID expects to purchase in 2017. In addition, we have a limited amount of direct commodity price exposure related 
to crude oil collected as part of our contractual pipeline loss allowance at Pony Express. During 2016, we began entering into 
derivative contracts for the sale of crude oil inventory.

We measure the risk of price changes in our natural gas swaps utilizing a sensitivity analysis model. The sensitivity 
analysis measures the potential income or loss (i.e., the change in fair value of the derivative instruments) based upon a 
hypothetical 10% movement in the underlying quoted market prices. In addition to these variables, the fair value of each 
portfolio is influenced by fluctuations in the notional amounts of the instruments and the discount rates used to determine the 
present values. We enter into derivative contracts solely for the purpose of mitigating the risks that accompany certain of our 
business activities and, therefore, both the sensitivity analysis model and the change in the market value of our outstanding 
derivative contracts are offset largely by changes in the value of the underlying physical commodity prices. 

The following table summarizes our commodity derivatives and the change in fair value that would be expected from a 

10% price increase or decrease as of December 31, 2016, assuming a parallel shift in the forward curve through the end of 
2017:

(1) Represents long natural gas swaps outstanding with a notional volume of approximately 0.4 Bcf covering a portion of 

the natural gas that is expected to be purchased by our Processing & Logistics segment throughout 2017.

(2) Represents short natural gas swaps outstanding with a notional volume of approximately 0.3 Bcf covering a portion of

The Commodity Futures Trading Commission ("CFTC") has promulgated regulations to implement the Dodd-Frank Wall
Street Reform and Consumer Protection Act's changes to the Commodity Exchange Act, including the definition of commodity-
based swaps subject to those regulations. The CFTC regulations implemented new reporting and record keeping requirements 
related to those swap transactions and a mandatory clearing and exchange-execution regime for various types, categories or 
classes of swaps, subject to certain exemptions, including the trade-option and end-user exemptions. Although we anticipate 
that most, if not all, of our swap transactions should qualify for an exemption to the clearing and exchange-execution 
requirements, we will still be subject to record keeping and reporting requirements. 

Interest Rate Risk

As described in "Liquidity and Capital Resources Overview" above, on September 1, 2016 we issued $400 million in 

5.50% senior notes due 2024. In addition, we currently have a $1.75 billion revolving credit facility with borrowings of 
approximately $1.0 billion as of December 31, 2016. Borrowings under the revolving credit facility will bear interest, at our 
option, at either (a) a base rate, which will be a rate equal to the greatest of (i) the prime rate, (ii) the U.S. federal funds rate 
plus 0.5% and (iii) a one-month reserve adjusted Eurodollar rate plus 1.00% or (b) a reserve adjusted Eurodollar Rate, plus, in 
each case, an applicable margin. The applicable margin ranges from 0.75% to 2.75%, based upon our total leverage ratio and 
whether we have elected the base rate or the reserve adjusted Eurodollar rate. 

We do not currently hedge the interest rate risk on our borrowings under the revolving credit facility. However, in the 
future we may consider hedging the interest rate risk or may consider choosing longer Eurodollar borrowing terms in order to 
fix all or a portion of our borrowings for a period of time. We estimate that a 1% increase in interest rates would decrease the 
fair value of the debt by $0.5 million based on our debt obligations as of December 31, 2016.

Credit Risk

We are exposed to credit risk. Credit risk represents the loss that we would incur if a counterparty fails to perform under its 

contractual obligations. We manage our exposure to credit risk associated with customers to whom we extend credit through a 
credit approval process which includes credit analysis, the establishment of credit limits and ongoing monitoring procedures. 
We may request letters of credit, cash collateral, prepayments or guarantees as forms of credit support. 

A substantial majority of our revenue is produced under long-term firm fee contracts with high-quality customers. The
customer base we currently serve under these contracts generally has a strong credit profile, with slightly under 45% of our 
revenues derived from customers who have an investment grade credit rating or are part of corporate families with investment 
grade credit ratings as of December 31, 2016. This represents a decrease in the portion of our revenues derived from customers 
with an investment grade credit rating from 2015, primarily as a result of credit downgrades at several of our customers and 
throughout the industry due to the soft commodity price environment.

We also have indirect credit risk exposure with respect to our investment in Rockies Express. See Item 1A.—Risk Factors 

for additional information.

Item 8. Financial Statements and Supplementary Data

Report of Independent Registered Public Accounting Firm

To the Partners of Tallgrass Energy Partners, LP

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income, equity and 
cash flows present fairly, in all material respects, the financial position of Tallgrass Energy Partners, LP and its subsidiaries at
December 31, 2016 and 2015, and the results of their operations and their cash flows for each of the three years in the period 
ended December 31, 2016, in conformity with accounting principles generally accepted in the United States of America. Also
in our opinion, the Partnership maintained, in all material respects, effective internal control over financial reporting as of 
December 31, 2016, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee 
of Sponsoring Organizations of the Treadway Commission (COSO). The Partnership's management is responsible for these 
financial statements, for maintaining effective internal control over financial reporting and for its assessment of the 
effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial 
Reporting appearing under Item 9A.  Our responsibility is to express opinions on these financial statements and on the 
Partnership's internal control over financial reporting based on our audits (which were integrated audits in 2016 and 2015). We
conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial 
statements are free of material misstatement and whether effective internal control over financial reporting was maintained in 
all material respects.  Our audits of the financial statements included examining, on a test basis, evidence supporting the 
amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by 
management, and evaluating the overall financial statement presentation.  Our audit of internal control over financial reporting 
included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness 
exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.  Our 
audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our 
audits provide a reasonable basis for our opinions.

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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (ii) 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 (iii) 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Description of Business

Tallgrass Energy Partners, LP ("TEP" or the "Partnership") is a publicly traded, growth-oriented limited partnership formed 

to own, operate, acquire and develop midstream energy assets in North America. "We," "us," "our" and similar terms refer to 
TEP together with its consolidated subsidiaries. Our operations are located in and provide services to certain key United States 
hydrocarbon basins, including the Denver-Julesburg, Powder River, Wind River, Permian and Hugoton-Anadarko Basins and 
the Niobrara, Mississippi Lime, Eagle Ford, Bakken, Marcellus, and Utica shale formations. Our reportable business segments 
are:

•

•

•

Crude Oil Transportation & Logistics—the ownership and operation of a FERC-regulated crude oil pipeline system 
and crude oil storage and terminalling facilities; 

Natural Gas Transportation & Logistics—the ownership and operation of FERC-regulated interstate natural gas 
pipelines and integrated natural gas storage facilities; and

Processing & Logistics—the ownership and operation of natural gas processing, treating and fractionation facilities, 
the provision of water business services primarily to the oil and gas exploration and production industry and the

outstanding.

(3) Tallgrass MLP GP, LLC (the "general partner") also holds all of TEP's incentive distribution rights.

(4) As of February 15, 2017, there were 72,973,429 total limited partner and general partner units outstanding. 

The term "Trailblazer Predecessor" refers to Trailblazer Pipeline Company LLC ("Trailblazer") for the period from 

November 13, 2012 to its acquisition by TEP on April 1, 2014, and the term "Pony Express Predecessor" refers to Pony Express 
for the period from November 13, 2012 to September 1, 2014, the date on which TEP acquired a 33.3% membership interest. 
Trailblazer Predecessor and Pony Express Predecessor are collectively referred to as the Predecessor Entities, as further 
discussed in Note 2 – Summary of Significant Accounting Policies. Financial results for all prior periods have been recast to 
reflect the operations of the Predecessor Entities. Predecessor Equity as presented in the consolidated financial statements 
represents the capital account activity of Trailblazer Predecessor prior to April 1, 2014 and of Pony Express Predecessor prior 
to September 1, 2014. For additional information regarding these acquisitions, see Note 4 – Acquisitions.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statements and related notes were prepared in accordance with the accounting principles 

contained in the Financial Accounting Standards Board's Accounting Standards Codification, the single source of generally 
accepted accounting principles in the United States of America ("GAAP"). In this report, the Financial Accounting Standards 
Board is referred to as the FASB and the FASB Accounting Standards Codification is referred to as the Codification or ASC.
Certain prior period amounts have been reclassified to conform to the current presentation.

The accompanying consolidated financial statements of TEP include historical cost-basis accounts of the assets of 

Trailblazer for the periods prior to April 1, 2014, the date TEP acquired Trailblazer from TD, and Pony Express for the periods 
prior to September 1, 2014, the date TEP acquired a controlling 33.3% membership interest in Pony Express, and include 
charges from TD for direct costs and allocations of indirect corporate overhead. Management believes that the allocation 
methods are reasonable, and that the allocations are representative of costs that would have been incurred on a stand-alone 
basis. TEP and the Predecessor Entities are all considered "entities under common control" as defined under GAAP and, as 
such, the transfers between the entities of the assets and liabilities have been recorded by TEP at historical cost.

As further discussed in Note 4 – Acquisitions, TEP closed the acquisition of Trailblazer on April 1, 2014 and the 

acquisition of a 33.3% membership interest in Pony Express effective September 1, 2014. As the acquisitions of Trailblazer and 
the initial 33.3% membership interest in Pony Express are considered transactions between entities under common control, and 
a change in reporting entity, the financial information presented has been recast to include Trailblazer and the 
initial 33.3% membership interest in Pony Express for all periods presented. The acquisitions of an additional 33.3% and 
31.3% membership interest in Pony Express effective March 1, 2015, and January 1, 2016, respectively, represent transactions 
between entities under common control and acquisitions of noncontrolling interests. As a result, financial information for 
periods prior to March 1, 2015 and January 1, 2016 have not been recast to reflect the additional 33.3% and 31.3% membership
interests.

The consolidated financial statements include the accounts of TEP and its subsidiaries and controlled affiliates. Significant 
intra-entity items have been eliminated in the presentation. Net equity contributions of the Predecessor Entities included in the 
consolidated statements of cash flows represent transfers of cash as a result of TD's centralized cash management systems prior 
to April 1, 2014 for Trailblazer and September 1, 2014 for Pony Express, under which cash balances were swept daily and 
recorded as loans from the subsidiaries to TD. These loans were then periodically recorded as equity distributions. Prior to 
January 1, 2016, Pony Express participated in a cash management agreement with TD, which currently holds a 2.0% common
membership interest in Pony Express, under which cash balances were swept periodically and recorded as loans from Pony 
Express to TD. Effective January 1, 2016, Pony Express entered into a cash management agreement with TEP.

Net income or loss from consolidated subsidiaries that are not wholly-owned by TEP is attributed to TEP and 

noncontrolling interests. This is done in accordance with substantive profit sharing arrangements, which generally follow the 
allocation of cash distributions and may not follow the respective ownership percentages held by TEP. Concurrent with TEP's
acquisition of an initial 33.3% membership interest in Pony Express effective September 1, 2014, TEP, TD, and Pony Express 
entered into the Second Amended and Restated Limited Liability Agreement of Tallgrass Pony Express Pipeline, LLC ("the 
Second Amended Pony Express LLC Agreement"), which provided TEP a minimum quarterly preference payment of $16.65
million (prorated to approximately $5.4 million for the quarter ended September 30, 2014) through the quarter ended 
September 30, 2015. Effective March 1, 2015 with TEP's acquisition of an additional 33.3% membership interest in Pony 

94

Express, the Second Amended Pony Express LLC Agreement was further amended (as amended, "the Pony Express LLC 
Agreement") to increase the minimum quarterly preference payment to $36.65 million (prorated to approximately $23.5
million for the quarter ended March 31, 2015) and extend the term of the preference period through the quarter ended 
December 31, 2015. The Pony Express LLC Agreement provides that the net income or loss of Pony Express be allocated, to 
the extent possible, consistent with the allocation of Pony Express cash distributions. Under the terms of the Pony Express LLC 
Agreement, Pony Express distributions and net income for periods beginning after December 31, 2015 are attributed to TEP
and its noncontrolling interests in accordance with the respective ownership interests.

A variable interest entity ("VIE") is a legal entity that possesses any of the following characteristics: an insufficient amount 

of equity at risk to finance its activities, equity owners who do not have the power to direct the significant activities of the 
entity (or have voting rights that are disproportionate to their ownership interest), or equity owners who do not have the 
obligation to absorb expected losses or the right to receive the expected residual returns of the entity. Companies are required to 
consolidate a VIE if they are its primary beneficiary, which is the enterprise that has a variable interest that could be significant 
to the VIE and the power to direct the activities that most significantly impact the entity's economic performance. We have 
presented separately in our consolidated balance sheets, to the extent material, the liabilities of our consolidated VIEs for which 
creditors do not have recourse to our general credit. Our consolidated VIEs do not have material assets that can only be used to 
settle specific obligations of the consolidated VIEs. Pony Express was considered to be a VIE under the applicable authoritative 
guidance prior to our acquisition of an additional 31.3% membership interest effective January 1, 2016. Effective January 1, 
2016, Pony Express is no longer considered to be a VIE. We continue to consolidate our membership interest in Pony Express.

Use of Estimates

Certain amounts included in or affecting these consolidated financial statements and related disclosures must be estimated, 
requiring management to make certain assumptions with respect to values or conditions which cannot be known with certainty 
at the time the financial statements are prepared. These estimates and assumptions affect the amounts reported for assets, 
liabilities, revenues, and expenses during the reporting period, and the disclosure of contingent assets and liabilities at the date 
of the financial statements. Management evaluates these estimates on an ongoing basis, utilizing historical experience, 
consultation with experts and other methods it considers reasonable in the particular circumstances. Nevertheless, actual results 
may differ significantly from these estimates. Any effects on our business, financial position or results of operations resulting 
from revisions to these estimates are recorded in the period in which the facts that give rise to the revision become known.

Cash and Cash Equivalents

We consider all highly liquid investments purchased with an original maturity of three months or less to be cash 

equivalents.

Net equity distributions of the Predecessor Entities included in the consolidated statements of cash flows represent 

transfers of cash as a result of TD's centralized cash management systems prior to April 1, 2014 for Trailblazer and September 
1, 2014 for Pony Express, under which cash balances were swept daily and recorded as loans from the subsidiaries to TD.
These loans were then periodically recorded as equity distributions. 

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are carried at their estimated collectible amounts. We make periodic reviews and evaluations of the 

appropriateness of the allowance for doubtful accounts based on a historical analysis of uncollected amounts, and adjustments 
are recorded as necessary for changed circumstances and customer-specific information. When specific receivables are 
determined to be uncollectible, the reserve and receivable are relieved. Our allowance for doubtful accounts totaled $0.6
million at December 31, 2016 and 2015.

Inventories

Inventories primarily consist of gas in underground storage, materials and supplies, natural gas liquids and crude oil. Gas 

in underground storage, sometimes referred to as working gas, and natural gas liquids are recorded at the lower of historical 
cost or market using the average cost method. As discussed further under "Revenue Recognition" below, a loss allowance is 
factored into the crude oil tariffs to offset losses in transit. As crude oil is transported, we earn oil for our services as pipeline 
allowance oil, which we can then sell. As pipeline allowance oil is accumulated, it is recorded as inventory at the lower of 
historical cost or market using the average cost method. Materials and supplies are valued at weighted average cost and 
periodically reviewed for physical deterioration and obsolescence. For additional information, see "Gas in Underground
Storage" below.

95

Accounting for Regulatory Activities

Regulated activities are accounted for in accordance with the "Regulated Operations" Topic of the Codification. This Topic

prescribes the circumstances in which the application of GAAP is affected by the economic effects of regulation. Regulatory 
assets and liabilities represent probable future revenues or expenses associated with certain charges and credits that will be 
recovered from or refunded to customers through the ratemaking process. We recorded regulatory assets of approximately $2.9
million and $2.8 million included in "Deferred charges and other assets" in the consolidated balance sheets at December 31,
2016 and 2015, respectively. Regulatory assets at December 31, 2016 and December 31, 2015 were primarily attributable to 
costs associated with both TIGT's 2015 Rate Case Filing and Trailblazer's 2013 Rate Case Filing as well as fuel tracker assets at 
our regulated natural gas pipelines. We recorded regulatory liabilities of approximately $1.7 million and $2.2 million included 
in "Other current liabilities" in the consolidated balance sheet at December 31, 2016 and 2015, respectively, related to fuel 
tracker liabilities at our regulated natural gas pipelines. For further information regarding our rate case filings and fuel tracker 
balances, see Note 17 – Regulatory Matters.

Property, Plant and Equipment

Property, plant and equipment is stated at historical cost, which for constructed plants includes indirect costs such as 
payroll taxes, other employee benefits, allowance for funds used during construction for regulated assets and other costs 
directly related to the projects. Expenditures that increase capacities, improve efficiencies or extend useful lives are capitalized 
and depreciated over the remaining useful life of the asset or major asset component. We also capitalize certain costs related to 
the construction of assets, including internal labor costs, interest and engineering costs.

Routine maintenance, repairs and renewal costs are expensed as incurred. The cost of normal retirements of the regulated 

depreciable utility property, plant and equipment, plus the cost of removal less salvage value and any gain or loss recognized, is 
recorded in accumulated depreciation and/or the negative salvage liability discussed under "Depreciation and Amortization"
below, as appropriate, with no effect on current period earnings. Gains or losses are recognized upon retirement of non-
regulated or regulated property, plant and equipment constituting an operating unit or system, and land, when sold or 
abandoned and costs of removal or salvage are expensed when incurred.

Intangible Assets

We account for intangible assets in accordance with ASC 805, which established that an intangible asset is identifiable if it 

meets either the separability criterion or the contractual-legal criterion. Further, in accordance with ASC 805, contract-based 
intangible assets represent the value of rights that arise from contractual arrangements. Use rights such as drilling, water, air,
timber cutting, and route authorities are an example of contract-based intangible assets. Intangible assets arose at Pony Express 
from the acquisition of rights associated with the ability and regulatory permissions to convert a section of TIGT's natural gas 
pipeline, which was subsequently purchased by Pony Express, to crude oil and includes the operational and financial benefits 
that accrue due to those rights and the ability to make that asset more valuable ("the Pony Express oil conversion use rights"). 
These intangible assets are amortized on a straight-line basis over a period of 35 years, the period of expected future benefit. 
Intangible assets arose at BNN Redtail, LLC ("Redtail") as a result of a significant customer contract with favorable market 
terms which was acquired as part of the Water Solutions transaction discussed in Note 4 – Acquisitions. This intangible asset 
was amortized on a straight-line basis over a period of 1.6 years, the remaining term of the contract at the time of acquisition, 
and was fully amortized as of December 31, 2015.

Impairment of Long-Lived Assets

We review our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying 

amount of an asset or asset group may not be recoverable. An impairment loss results when the estimated undiscounted future 
net cash flows expected to result from the asset or asset group's use and its eventual disposition are less than its carrying 
amount. We assess our long-lived assets for impairment in accordance with the relevant Codification guidance. A long-lived 
asset or asset group is tested for impairment whenever events or changes in circumstances indicate its carrying amount may 
exceed its fair value.

Examples of long-lived asset impairment indicators include:

•

•

•

a significant decrease in the market value of a long-lived asset or asset group;

a significant adverse change in the extent or manner in which a long-lived asset or asset group is being used or in its 
physical condition;

a significant adverse change in legal factors or in the business climate could affect the value of long-lived asset or 
asset group, including an adverse action or assessment by a regulator which would exclude allowable costs from the 
rate-making process;

96

•

•

•

an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction 
of the long-lived asset or asset group;

a current period operating cash flow loss combined with a history of operating cash flow losses or a projection or 
forecast that demonstrates continuing losses associated with the use of a long-lived asset or asset group; and

a current expectation that, more likely than not, a long-lived asset or asset group will be sold or otherwise disposed of 
significantly before the end of its previously estimated useful life. 

When an impairment indicator is present, we first assess the recoverability of the long-lived assets by comparing the sum 
of the undiscounted future cash flows expected to result from the use and eventual disposition of the asset or asset group to its 
carrying amount. If the carrying amount is higher than the undiscounted future cash flows, the fair value of the asset or asset 
group is assessed using a discounted cash flow analysis and used to determine the amount of impairment, if any, to be 
recognized.

Gas in Underground Storage

Gas in underground storage represents the cost of base gas, which refers to the volumes necessary to maintain pressure and 

deliverability requirements in our storage facilities. We record base gas as a component of property, plant and equipment.

We maintain working gas in our underground storage facilities on behalf of certain third parties. We receive a fee for our 

storage services but do not reflect the value of third-party gas in the accompanying consolidated financial statements. We
occasionally acquire volumes of working gas for our own account. These volumes of working gas are recorded as natural gas 
inventory at the lower of cost or market. 

Depreciation and Amortization

For non-regulated assets, we have elected to use the straight-line method of depreciation. For our regulated assets, we have 
elected to compute depreciation using a composite method employed by applying a single depreciation rate to a group of assets 
with similar economic characteristics. This composite method of depreciation approximates a straight-line method of 
depreciation. The depreciation rates for our regulated natural gas pipeline assets include two components, one based on 
economic service life (capital recovery) and one based on net costs of removal (negative salvage). The accumulated liability 
related to negative salvage is classified as "Other long-term liabilities and deferred credits" in our consolidated balance sheets.

The rates of depreciation for the various classes of depreciable assets are as follows: 

Crude oil pipelines .......................................................................
Natural gas pipelines ....................................................................
Processing & treating assets .........................................................
Water business assets....................................................................
Replacement Gas Facilities (1) ......................................................

2.9 - 25.0%

(1) Represents the Replacement Gas Facilities as discussed in Note 5 – Related Party Transactions and Note 17 – 

Regulatory Matters.

Gas Imbalances

Gas imbalances receivable and payable represent the difference between customer nominations and actual gas receipts 

from and gas deliveries to interconnecting pipelines under various operational balancing and imbalance agreements. Gas 
imbalances are either made up in-kind or settled in cash, subject to the terms and valuations of the various agreements. 
Imbalances are valued at applicable average market index prices.

Deferred Financing Costs

Costs incurred in connection with the issuance of long-term debt are deferred and amortized over the related financing 

period using the effective interest method. Deferred financing costs associated with long-term debt are presented with the 
corresponding debt in our consolidated balance sheets. Deferred financing costs associated with our revolving credit facility are 
presented as noncurrent assets in our consolidated balance sheets.

97

Goodwill

We evaluate goodwill for impairment on an annual basis and whenever events or changes in circumstances necessitate an 

evaluation for impairment. Examples of such facts and circumstances include changes in the magnitude of the excess of fair 
value over carrying amount in the last valuation or changes in the business environment. Our annual impairment testing date is 
August 31. We evaluate goodwill for impairment at the reporting unit level, which is an operating segment as defined in the 
segment reporting guidance of the Codification, using either the qualitative assessment option or the two-step test approach 
depending on facts and circumstances of the reporting unit. If we, after performing the qualitative assessment, determine it is 
"more likely than not" that the fair value of a reporting unit is greater than its carrying amount, the two-step impairment test is 
unnecessary. When goodwill is evaluated for impairment using the two-step test, the carrying amount of the reporting unit is 
compared to its fair value in Step 1 and if the fair value exceeds the carrying amount, Step 2 is unnecessary. If the carrying 
amount exceeds the reporting unit's fair value, this could indicate potential impairment and Step 2 of the goodwill evaluation 
process is required to determine if goodwill is impaired and to measure the amount of impairment loss to recognize, if any.
When Step 2 is necessary, the fair value of individual assets and liabilities is determined using valuations, or other observable 
sources of fair value, as appropriate. If the carrying amount of goodwill exceeds its implied fair value, the excess is recognized 
as an impairment loss. See Note 8 – Goodwill and Other Intangible Assets for additional information regarding impairment 
testing performed during 2016.

Investment in Unconsolidated Affiliates

We use the equity method to account for investments in 20% or greater owned affiliates that are not variable interest 
entities and where we do not have the ability to exercise control, and for investments in less than 20% owned affiliates where 
we have the ability to exercise significant influence.

We evaluate our investments in unconsolidated affiliates for impairment whenever events or changes in circumstances 
indicate that the carrying value of such investments may have experienced a decline in value. When there is evidence of loss in 
value, we compare the estimated fair value of the investment to the carrying value of the investment to determine whether 
impairment has occurred. We assess the fair value of our investments in unconsolidated affiliates using commonly accepted 
techniques, and may use more than one method, including, but not limited to, recent third party comparable sales and 
discounted cash flow models. The difference between the carrying amount of the unconsolidated affiliates and their estimated 
fair value is recognized as an impairment loss when the loss in value is deemed to be other-than-temporary. See Note 9 – 
Investments in Unconsolidated Affiliates for additional information regarding our investment in unconsolidated affiliates.

Revenue Recognition

We recognize revenues as services are rendered or goods are sold to a purchaser at a fixed and determinable price, delivery 

has occurred, title has transferred and collectability is reasonably assured. We provide various types of natural gas storage and 
transportation services and crude oil transportation services to our customers in which the commodity remains the property of 
these customers at all times.

Crude oil transportation services occur in the Crude Oil Transportation & Logistics segment. We provide various types of 

crude oil transportation services to our customers and, other than pipeline allowance oil, do not take title to the crude oil and do 
not incur the risks and rewards of ownership. In many cases the customer has committed to ship a fixed quantity of oil barrels 
per month. For barrels physically received by us and delivered to the customers' agreed upon destination point, revenue is 
recognized in the period the service is provided. Shipper deficiencies, or barrels committed by the customer to be transported in 
a month but not physically received by us for transport or delivered to the customers' agreed upon destination point, are charged
at the committed tariff rate per barrel and recorded as a liability until the barrels are physically transported and delivered. In the 
case of non-committed shippers, revenue is recognized in the same manner utilized for the barrels physically transported and 
delivered. A loss allowance is factored into the crude oil tariffs to offset losses in transit. As crude oil is transported, we earn oil 
for our services as pipeline allowance oil. Any pipeline allowance oil that remains after replacing losses in transit can be 
sold. We take title and record revenue at market prices when the volumes included in the pipeline loss allowance are delivered 
from the customer. When pipeline loss allowance oil is eventually sold, we record revenue at the contractual sales price and 
cost of sales at average cost as discussed in "Inventories" above. 

98

Natural gas transportation and storage services occur in the Natural Gas Transportation & Logistics segment. In many 
cases (generally described as "firm service"), the customer pays a two-part rate that includes (i) a fee reserving the right to 
transport or store natural gas in our facilities and (ii) a per-unit rate for volumes actually transported or injected into/withdrawn 
from storage. The fee-based component of the overall rate is recognized as revenue in the period the service is provided. The
per-unit charge is recognized as revenue when the volumes are delivered to the customers' agreed upon delivery point, or when 
the volumes are injected into/withdrawn from our storage facilities. In other cases (generally described as "interruptible 
service"), there is no fixed fee associated with the services because the customer accepts the possibility that service may be 
interrupted at our discretion in order to serve customers who have purchased firm service. In the case of interruptible service, 
revenue is recognized in the same manner utilized for the per-unit rate for volumes actually transported under firm service 
agreements. In addition to "firm" and "interruptible" transportation services, we also provide natural gas park and loan services 
to assist customers in managing short-term gas surpluses or deficits. Revenues are recognized as services are provided, based 
on the terms negotiated under these contracts.

Natural gas liquids sales occur in the Processing & Logistics segment and consist of the sale of outputs from our 

processing plants and the marketing of natural gas liquids that are delivered by our suppliers under either fee-based 
arrangements or percent-of-proceeds arrangements. Under these arrangements, we treat and process the natural gas delivered 
by our suppliers, and then sell the resulting NGLs and condensate based on published index market prices. We remit to the 
producers an agreed-upon percentage of the actual proceeds that we receive from our sales of the NGLs and condensate. We
keep the difference between the proceeds received and the amount remitted back to the producer. We generally report gross 
revenues in the consolidated statements of income, as we typically act as the principal in these transactions, take custody of the 
product, and incur the risks and rewards of ownership. Processing and other revenues primarily represent fees for processing, 
treating and fractionation of natural gas and NGLs earned under fee-based arrangements and revenue from water services 
earned in the Processing & Logistics segment.

Natural gas sales occur in both the Natural Gas Transportation & Logistics segment and in the Processing & Logistics 
segment. In the Natural Gas Transportation & Logistics segment, transportation services revenue is recognized when a portion 
of the natural gas transported by customers is collected as a contractual fee to compensate us for fuel consumed by pipeline and 
storage operations. We take title and record revenue at market prices when the volumes included in the contractual fee are 
delivered from the customer and injected into our storage facility. When the excess volumes are eventually sold, we record 
natural gas sales revenue at the contractual sales price and cost of sales at average cost. In addition, when operational 
conditions allow, we occasionally sell "base gas," which refers to the minimum volume of natural gas required in order to 
operate the storage facility. In the Processing & Logistics segment, we purchase natural gas primarily for use in our operations 
and for meeting contractual requirements to deliver natural gas to certain customers. In addition, some of our contractual 
arrangements allow us to keep a portion of the processed natural gas as compensation for processing services. We generate 
revenue by selling the volumes of natural gas received or purchased that exceed our business needs.

Commitments and Contingencies

We recognize liabilities for other commitments and contingencies when, after fully analyzing the available information, we 

determine it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. When a range of 
probable loss can be estimated, we accrue the most likely amount, or if no amount is more likely than another, we accrue the 
minimum of the range of probable loss.

Environmental Costs

We expense or capitalize, as appropriate, environmental expenditures that relate to current operations. We expense amounts 

that relate to an existing condition caused by past operations that do not contribute to current or future revenue generation. We
do not discount environmental liabilities to a net present value, and record environmental liabilities when environmental 
assessments and/or remedial efforts are probable and costs can be reasonably estimated. Recording of these accruals coincides 
with the completion of a feasibility study or a commitment to a formal plan of action. Estimates of environmental liabilities are 
based on currently available facts and presently enacted laws and regulations taking into consideration the likely effects of 
other factors including our prior experience in remediating contaminated sites, other companies' clean-up experience and data 
released by government organizations. Our estimates are subject to revision in future periods based on actual cost or new 
information.

Fair Value

Fair value, as defined in the Codification, is the price that would be received to sell an asset or paid to transfer a liability in 
an orderly transaction between market participants at the measurement date, or exit price. We apply the fair value measurement 
guidance to financial assets and liabilities in determining the fair value of derivative assets and liabilities, and to nonfinancial 
assets and liabilities upon the acquisition of a business or in conjunction with the measurement of an impairment loss on an 
asset group or goodwill under the accounting guidance for the impairment of long-lived assets or goodwill.

99

The fair value measurement accounting guidance requires that we make assumptions that market participants would use in 
pricing an asset or liability based on the best information available. These factors include nonperformance risk (the risk that the 
obligation will not be fulfilled) and credit risk of the reporting entity (for liabilities) and of the counterparty (for assets). The
fair value measurement guidance prohibits the inclusion of transaction costs and any adjustments for blockage factors in 
determining the instruments' fair value. The principal or most advantageous market should be considered from the perspective 
of the reporting entity.

Fair value, where available, is based on observable market prices. Where observable market prices or inputs are not 
available, different valuation models and techniques are applied. These models and techniques attempt to maximize the use of 
observable inputs and minimize the use of unobservable inputs. The process involves varying levels of management judgment, 
the degree of which is dependent on the price transparency of the instruments or market and the instruments' complexity.

To increase consistency and enhance disclosure of fair value, the Codification creates a fair value hierarchy to prioritize the 
inputs used to measure fair value into three categories. An asset or liability's level within the fair value hierarchy is based on the 
lowest level of input significant to the fair value measurement, where Level 1 is the highest and Level 3 is the lowest. The three 
levels are defined as follows:

•

•

•

Level 1 Inputs-quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity 
has the ability to access at the measurement date;

Level 2 Inputs-inputs other than quoted prices included within Level 1 that are observable for the asset or liability,
either directly or indirectly. If the asset or liability has a specified (contractual) term, a Level 2 input must be 
observable for substantially the full term of the asset or liability; and

Level 3 Inputs-unobservable inputs for the asset or liability. These unobservable inputs reflect the entity's own 
assumptions about the assumptions that market participants would use in pricing the asset or liability, and are 
developed based on the best information available in the circumstances (which might include the reporting entity's 
own data).

Any transfers between levels within the fair value hierarchy are recognized at the end of the reporting period.

For information regarding financial instruments measured at fair value on a recurring basis, see Note 10 – Risk

Management. For information regarding the fair value of financial instruments not measured at fair value in the consolidated 
balance sheets, see Note 11 – Long-term Debt.

Risk Management Activities

We utilize energy derivatives for the purpose of mitigating our risk resulting from fluctuations in the market price of crude 
oil and natural gas. We record derivative contracts at their estimated fair values as of each reporting date. For more information 
on our risk management activities, see Note 10 – Risk Management.

Equity-Based Compensation

Equity-based compensation grants are measured at their grant date fair value and related compensation cost is recognized 
over the vesting period of the grant. Compensation cost for awards with graded vesting provisions is recognized on a straight-
line basis over the requisite service period of each separately vesting portion of the award. As discussed in Note 16 – Equity-
Based Compensation, a portion of the expense recognized relating to equity-based compensation grants is charged to TD.

Income Taxes

Prior to September 1, 2014, TEP was comprised solely of limited liability companies that were flow-through entities (that 

is, partnerships or disregarded entities) for income tax purposes. As discussed above, effective September 1, 2014 TEP acquired 
a 33.3% membership interest in Pony Express, which in turn owned 99.8% of Tallgrass Pony Express Pipeline (Colorado), Inc. 
("PXP Colorado"), a C corporation. At that time, PXP Colorado was in the process of constructing the lateral in Northeast 
Colorado and had not yet commenced operations or generated any income. PXP Colorado was subsequently merged into Pony 
Express prior to the commencement of commercial operations on the lateral in Northeast Colorado.

On September 14, 2015, TEP, through its membership interest in Pony Express, formed a new C corporation, Tallgrass

Colorado Pipeline, Inc. ("Tallgrass Colorado"), which is 99.8% owned by Pony Express. The remaining 0.2% interest in 
Tallgrass Colorado is held by direct and indirect wholly owned subsidiaries of TEP. Tallgrass Colorado was formed for the 
purpose of the potential construction of a lateral pipeline that would interconnect with the Pony Express System's existing 
lateral in Northeast Colorado and has not yet commenced operations or generated any income. In addition, during the year 
ended December 31, 2015, we formed Tallgrass Energy Finance Corp., a wholly owned subsidiary that has no material assets 
and was formed for the sole purpose of being a co-issuer of our senior notes issued on September 1, 2016. Accordingly, no 
provision for federal or state income taxes has been recorded in our consolidated financial statements.

Accounting Pronouncements Not Yet Adopted

Revenue Recognition

In May 2014, the FASB issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with 
Customers (Topic 606). ASU 2014-09 provides a comprehensive and converged set of principles-based revenue recognition 
guidelines which supersede the existing industry and transaction-specific standards. The core principle of the new guidance is 
that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that 
reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this core 
principle, entities must apply a five-step process to (1) identify the contract with a customer; (2) identify the performance 
obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations 
in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 also 
mandates disclosure of sufficient information to enable users of financial statements to understand the nature, amount, timing 
and uncertainty of revenue and cash flows arising from contracts with customers. The disclosure requirements include 
qualitative and quantitative information about contracts with customers, significant judgments and changes in judgments, and 
assets recognized from the costs to obtain or fulfill a contract.

Throughout 2015 and 2016, the FASB has issued a series of subsequent updates to the revenue recognition guidance in 
Topic 606, including ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, 
ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting 
Revenue Gross versus Net), ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance 
Obligations and Licensing, ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope 
Improvements and Practical Expedients, and ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, 
Revenue from Contracts with Customers.

The amendments in ASU 2014-09, ASU 2016-08, ASU 2016-10, ASU 2016-12, and ASU 2016-20 are effective for public 

entities for annual reporting periods beginning after December 15, 2017, and for interim periods within that reporting period. 
Early application is permitted for annual reporting periods beginning after December 15, 2016.

We are currently evaluating the impact of our pending adoption of the revised guidance. The status of our implementation 

is as follows:

• We have formed an implementation team that meets to discuss implementation challenges, technical interpretations, 

industry-specific treatment of certain revenue contract types, and project status.

• We are currently reviewing contracts for each revenue stream identified within each of our business segments. 

Through this process, we are determining and documenting expected changes in revenue recognition upon adoption of 
the revised guidance.

• We plan to evaluate the potential information technology and internal control changes that will be required for 

adoption based on the findings from our contract review process.

• We plan to provide internal training and awareness related to the revised guidance to the key stakeholders throughout 

our organization.

We will continue to conduct our contract review process throughout 2017 and, as a result, areas of impact may be 

identified. We are in the process of quantifying the impact of adoption but cannot reasonably estimate such amount at this time. 
We expect to adopt the new standard on January 1, 2018 using the modified retrospective approach. This approach allows us to 
apply the new standard to (i) all new contracts entered into after January 1, 2018 and (ii) all existing contracts for which all (or 
substantially all) of the revenue has not been recognized under legacy revenue guidance as of January 1, 2018 through a 
cumulative adjustment to equity. Consolidated revenues presented in our comparative financial statements for periods prior to 
January 1, 2018 would not be revised.

ASU No. 2016-02, "Leases (Topic 842)"

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). ASU 2016-02 provides a comprehensive update 

to the lease accounting topic in the Codification intended to increase transparency and comparability among organizations by 
recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. 
The amendments in ASU 2016-02 include a revised definition of a lease as well as certain scope exceptions. The changes 
primarily impact lessee accounting, while lessor accounting is largely unchanged from previous GAAP.

The amendments in ASU 2016-02 are effective for public entities for annual reporting periods beginning after December 
15, 2018, and for interim periods within that reporting period. Early application is permitted. We are currently evaluating the 
impact of ASU 2016-02.

101

ASU No. 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment 

Accounting"

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to 

Employee Share-Based Payment Accounting. ASU 2016-09 simplifies several aspects of the accounting for share-based 
payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and 
classification on the statement of cash flows. Among other changes, ASU 2016-09 allows an entity to make an entity-wide 
accounting policy election to either estimate the number of awards expected to vest (consistent with current GAAP) or account 
for forfeitures when they occur.

The amendments in ASU 2016-09 are effective for public entities for annual periods and interim periods within those 
annual periods beginning after December 15, 2016. Early adoption is permitted. We are currently evaluating the impact of ASU
2016-09, but do not anticipate a material impact on our consolidated financial statements.

ASU No. 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business"

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a 

Business. ASU 2017-01 clarifies the definition of a business with the objective of adding guidance to assist entities with 
evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses by providing a 
screen to determine when an integrated set of assets and activities is not a business. The screen requires that when substantially 
all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of 
similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further 
evaluated. The ASU also narrows the definition of the term "output" so that the term is consistent with how outputs are 
described under the revenue recognition guidance in Topic 606.

The amendments in ASU 2017-01 are effective for public entities for annual periods and interim periods within those 
annual periods beginning after December 15, 2017. Early adoption is permitted in certain circumstances. We are currently 
evaluating the impact of ASU 2017-01, but do not anticipate a material impact on our consolidated financial statements.

ASU No. 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment"

In January 2017, the FASB issued ASU No. 2017-04, which simplifies the subsequent measurement of goodwill by 

eliminating "Step 2" from the goodwill impairment test, which involved calculating the implied fair value of goodwill by 
determining the fair value at the impairment testing date of a reporting unit's assets and liabilities. Instead, under the simplified 
test approach, and entity should recognize an impairment charge for the amount by which the carrying amount exceeds the 
reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that 
reporting unit.

The amendments in ASU 2017-04 are effective for public entities for annual periods and interim periods within those 
annual periods beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests 
performed on testing dates after January 1, 2017. We are currently evaluating the impact of ASU 2017-04.

Accounting Pronouncements Recently Adopted

ASU No. 2016-15, "Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments"

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash 

Receipts and Cash Payments. ASU 2016-15 provides explicit guidance on accounting for eight specific cash flow issues with 
the objective of reducing diversity in practice, including debt prepayment or debt extinguishment costs, settlement of certain 
debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of 
insurance claims, proceeds from the settlement of corporate owned life insurance policies, distributions received from equity 
method investees, beneficial interests in securitization transactions and separately identifiable cash flows and application of the 
predominance principle. 

The amendments in ASU 2016-15 are effective for public entities for fiscal years beginning after December 15, 2017, and 
interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. During the third 
quarter of 2016, we adopted the standard on a retrospective basis for all periods presented. The adoption of ASU 2016-15 did 
not have a material impact on our financial position, results of operations, or cash flows.

102

ASU No. 2015-16, "Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments"

In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting

for Measurement-Period Adjustments. ASU 2015-16 simplifies the accounting for measurement-period adjustments for 
provisional amounts recognized in a business combination by eliminating the requirement for an acquirer to retrospectively 
account for measurement-period adjustments. Under the updated guidance, the acquirer must recognize adjustments in the 
reporting period in which the adjustment amounts are determined and the effect on earnings as a result of the change to the 
provisional amounts must be calculated as if the accounting had been completed at the acquisition date.

The amendments in ASU 2015-16 were effective for public entities for annual periods and interim periods within those 

annual periods beginning after December 15, 2015. The adoption of ASU 2015-16 did not have a material impact on our 
financial position and results of operations.

ASU No. 2015-02, "Consolidation (Topic 810): Amendments to the Consolidation Analysis"

In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810) - Amendments to the Consolidation 
Analysis. ASU 2015-02 changes the analysis that a reporting entity must perform to determine whether it should consolidate 
certain types of legal entities. ASU 2015-02 modifies the evaluation of whether limited partnerships and other similar legal 
entities are considered VIEs or voting interest entities, eliminates the presumption that a general partner should consolidate a 
limited partnership, and changes certain aspects of the consolidation analysis for reporting entities that are involved with VIEs,
particularly for those with fee arrangements and related party relationships.

The amendments in ASU 2015-02 were effective for public entities for annual periods and interim periods within those 

annual periods beginning after December 15, 2015. The adoption of ASU 2015-02 did not have a material impact on our 
financial position and results of operations.

ASU No. 2014-12, "Compensation - Stock Compensation (Topic 718), Accounting for Share-Based Payments When the 

Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period"

In June 2014, the FASB issued ASU No. 2014-12, Compensation - Stock Compensation (Topic 718), Accounting for 
Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite 
Service Period. ASU 2014-12 provides explicit guidance on accounting for share-based payments requiring a specific 
performance target to be achieved in order for employees to become eligible to vest in the awards when that performance target
may be achieved after the requisite service period for the award. The ASU requires that such performance targets be treated as a 
performance condition, and should not be reflected in the estimate of the grant-date fair value of the award. Instead, 
compensation cost should be recognized in the period in which it becomes probable that the performance target will be 
achieved.

ASU 2014-12 was effective for annual periods and interim periods within those annual periods beginning after December 

15, 2015. The adoption of ASU 2014-12 did not have a material impact on our financial position and results of operations.

3. Variable Interest Entities

Prior to January 1, 2016, Pony Express was considered to be a VIE as TEP did not have the obligation to absorb expected 
losses from Pony Express as a result of the minimum quarterly preference payments as discussed in Note 4 – Acquisitions. In 
addition, for the period from our acquisition of the initial 33.3% membership interest effective September 1, 2014 to our 
acquisition of an additional 33.3% membership interest effective March 1, 2015, TEP, as the managing member of Pony 
Express, had voting rights disproportionate to its ownership interest. As a result, we determined that Pony Express was a VIE of 
which TEP was the primary beneficiary and consolidated Pony Express accordingly. As discussed in Note 2 – Summary of 
Significant Accounting Policies, in conjunction with our acquisition of an additional 31.3% membership interest effective
January 1, 2016, Pony Express is no longer considered to be a VIE. We continue to consolidate our membership interest in 
Pony Express.

We have not provided any additional financial support to Pony Express other than our initial capital contribution of $570

million and our pro rata portion of expansion capital projects as discussed below, and have no contractual commitments or 
obligations to provide additional financial support. To the extent the costs of construction of the Pony Express System, 
including the lateral in Northeast Colorado, exceed the $270 million retained by Pony Express as discussed in Note 4 – 
Acquisitions, TD is obligated to fund the remaining costs. As of December 31, 2015, the costs to complete construction 
exceeded the amount retained, and as such TD continued to fund remaining costs associated with construction of the mainline 
and lateral in Northeast Colorado. Although TEP has no obligation to provide further financial support to Pony Express, 
expansion capital projects are funded by TEP and TD on a pro rata basis in accordance with the Pony Express LLC Agreement.
Contributions from TEP to Pony Express to fund expansion capital projects totaled $4.4 million for the year ended 
December 31, 2015.

4. Acquisitions

TEP Acquisition of a 25% Membership Interest in Rockies Express Pipeline LLC

On May 6, 2016, TD assigned us its right to purchase a 25% membership interest in Rockies Express from a unit of 

Sempra U.S. Gas and Power ("Sempra") pursuant to the purchase agreement originally entered into between TD's wholly-
owned subsidiary and Sempra in March 2016. Subsequently on May 6, 2016, we closed the purchase of a 25% membership 
interest in Rockies Express from Sempra pursuant to the purchase agreement for cash consideration of approximately $436.0
million, after making the adjustments to the purchase price required by the purchase agreement. For additional information, 
see Note 9 – Investments in Unconsolidated Affiliates.

TEP Acquisitions of 98% of Pony Express

Effective September 1, 2014, TEP acquired a controlling 33.3% membership interest in Pony Express for total 

consideration of approximately $600 million. At closing, Pony Express, TD, and TEP entered into the Second Amended Pony 
Express LLC Agreement, which set forth the relative rights of TD and TEP as the owners of Pony Express. Of the total 
consideration of $600 million, TEP directly paid TD $30 million, consisting of $27 million in cash and 70,340 TEP common 
units with an aggregate fair value of approximately $3 million, in exchange for the transfer by TD to TEP of 
a 1.9585% membership interest in Pony Express (computed before giving effect to the issuance of the new membership interest 
by Pony Express to TEP). TEP also contributed cash of $570 million to Pony Express in exchange for a newly issued 
membership interest which, when combined with the membership interest transferred from TD and the parties' entry at closing 
into the Second Amended Pony Express LLC Agreement, constituted TEP's 33.3% membership interest in Pony Express, which 
represented 100% of the preferred membership units issued by Pony Express. Of the $570 million cash consideration received 
by Pony Express, $300 million was immediately distributed to TD at closing and $270 million was retained by Pony Express to 
fund the estimated remaining costs of construction for the Pony Express System and the lateral in Northeast Colorado. The
$270 million cash balance was subsequently swept to TD under a cash management agreement between Pony Express and TD
and was recorded as a related party loan which bears interest at TD's incremental borrowing rate. The related party loan was 
repaid in full in 2015.

The terms of TEP's first acquisition of a 33.3% membership interest in Pony Express provided TEP a minimum quarterly 

preference payment of $16.65 million through the quarter ended September 30, 2015 (prorated to approximately $5.4
million for the quarter ended September 30, 2014) with distributions thereafter shared in accordance with the terms of the 
Second Amended Pony Express LLC Agreement. At the effective date of that transaction, TEP determined that Pony Express 
was a VIE of which TEP was the primary beneficiary, and consolidated Pony Express accordingly. For additional discussion 
and disclosure, see Note 3 – Variable Interest Entities. The acquisition of the initial 33.3% membership interest in Pony Express 
represented a transaction between entities under common control and a change in reporting entity.

Effective March 1, 2015, TEP acquired an additional 33.3% membership interest in Pony Express for cash consideration 
of $700 million. At closing, Pony Express, TD, and TEP entered into the Pony Express LLC Agreement, which sets forth the 
relative rights of TD and TEP as the owners of Pony Express. The terms of the transaction increased the minimum quarterly 
preference payment provided to TEP to $36.65 million through the quarter ending December 31, 2015 (prorated to 
approximately $23.5 million for the quarter ended March 31, 2015) with distributions thereafter shared in accordance with the 
terms of the Pony Express LLC Agreement.

104

 
Upon the effective date of the second acquisition, TEP reevaluated its VIE assessment and determined that Pony Express 

continued to be considered a VIE of which TEP is the primary beneficiary. The acquisition of the additional 33.3% membership
interest in Pony Express represents a transaction between entities under common control and an acquisition of noncontrolling 
interests. As a result, financial information for periods prior to the transaction have not been recast to reflect the 
additional 33.3% membership interest. The transaction resulted in a deemed distribution to our general partner as discussed 
further in Note 12 – Partnership Equity and Distributions.

Effective January 1, 2016, TEP acquired an additional 31.3% membership interest in Pony Express in exchange for cash 

consideration of $475 million and 6,518,000 TEP common units (valued at approximately $268.6 million based on the 
December 31, 2015 closing price of our common units) issued to TD, for total consideration of approximately $743.6 million.
The transaction increased our aggregate membership interest in Pony Express to 98%. As part of the transaction, TD granted us 
an 18-month call option covering the newly issued 6,518,000 common units at a price of $42.50. On the effective date of the 
acquisition, the call option was valued at $46.0 million. As discussed in Note 10 – Risk Management, in July 2016 and October 
2016, we partially exercised the option covering 3,563,146 and 1,251,760 of the common units, respectively. On February 1,
2017, we exercised the remainder of the call option covering an additional 1,703,094 common units, leaving no remaining 
common units subject to the call option as of such date. As a result of the partial exercises in 2016, TEP derecognized a portion 
of the derivative asset balance, recognizing approximately $34.0 million through equity for year ended December 31, 2016, as 
discussed further in Note 12 – Partnership Equity and Distributions.

The acquisition of the additional 31.3% membership interest in Pony Express represents a transaction between entities 
under common control and an acquisition of noncontrolling interests. As a result, financial information for periods prior to the 
transaction has not been recast to reflect the additional 31.3% membership interest. The transaction resulted in a deemed 
distribution to our general partner as discussed further in Note 12 – Partnership Equity and Distributions.

Cash outflows to acquire an additional noncontrolling interest in Pony Express are classified as an investing activity in the 

accompanying consolidated statements of cash flows to the extent the consideration paid was used to directly fund the 
construction of the underlying assets by the noncontrolling member. Cash outflows to acquire an additional noncontrolling 
interest in excess of the cost to construct the underlying assets are classified as financing activities. For the year ended 
December 31, 2016, $49.1 million of the $475 million paid to acquire the additional 31.3% membership interest in Pony 
Express was classified as an investing activity and $425.9 million was classified as a financing activity.

TEP Acquisition of BNN Western, LLC

On December 16, 2015, Whiting Oil and Gas Corporation ("Whiting"), Redtail, and BNN Western, LLC ("Western"), a 
newly formed Delaware limited liability company, entered into a definitive Transfer, Purchase and Sale Agreement, pursuant to 
which Redtail acquired 100% of the outstanding membership interests of Western from Whiting in exchange for total cash 
consideration of $75 million. Western's assets consist of a fresh water delivery and storage system and produced water 
gathering and produced water disposal system, which together comprise 62 miles of pipeline along with associated fresh water 
ponds and disposal wells. As part of the transaction with Whiting, Whiting also executed a five-year fresh water service 
contract and a nine-year gathering and disposal contract, each of which commenced in December 2015. 

At December 31, 2015, the assets acquired and liabilities assumed in the acquisition were recorded at provisional amounts 

based on the preliminary purchase price allocation. The $75 million purchase price of the assets was allocated entirely to 
property, plant and equipment. No adjustments were made to these provisional amounts and the allocation of assets acquired 
and liabilities assumed in the acquisition was considered final as of September 30, 2016.

Unaudited pro forma revenue and net income attributable to partners for the years ended December 31, 2015 and 2014 is 

presented below as if the acquisition of Western had been completed on January 1, 2014:

The pro forma financial information is not necessarily indicative of what the actual results of operations or financial 
position of TEP would have been if the transactions had in fact occurred on the date or for the period indicated, nor do they 
purport to project the results of operations or financial position of TEP for any future periods or as of any date. The pro forma 
financial information does not give effect to any cost savings, operating synergies, or revenue enhancements expected to result 
from the transactions or the costs to achieve these cost savings, operating synergies, and revenue enhancements. The pro forma 
revenue and net income includes adjustments to give effect to TEP's consolidated interest in the estimated results of operations 
of Western for the periods presented.

TEP Acquisition of Trailblazer

On April 1, 2014, TEP closed the acquisition of Trailblazer from a wholly owned subsidiary of TD for total consideration 
valued at approximately $164 million, consisting of $150 million in cash and the issuance of 385,140 common units (valued at 
approximately $14 million based on the March 31, 2014 closing price of TEP's common units). On that same date, the general 
partner contributed additional capital in the amount of approximately $263,000 in exchange for the issuance of 7,860 general
partner units in order to maintain its 2% general partner interest. The acquisition of Trailblazer represents a change in reporting 
entity and a transaction between entities under common control. The excess purchase price over the net book value of 
Trailblazer's assets and liabilities was accounted for as a deemed distribution as discussed further in Note 12 – Partnership
Equity and Distributions.

Formation of BNN Water Solutions, LLC

On November 26, 2013, TEP, through its wholly-owned subsidiary Tallgrass Energy Investments, LLC ("TEI"), entered 
into a joint venture agreement with BNN Energy LLC ("BNN") to form Grasslands Water Services I, LLC ("GWSI"), which 
subsequently built and began operating an intrastate fresh water pipeline in Colorado. TEP accounted for its 50% equity interest 
in GWSI as an equity method investment. On May 13, 2014, TEI entered into a contribution agreement with BNN and several 
other parties to form a new entity known as Water Solutions. Under the terms of the contribution agreement, TEI agreed to 
contribute its existing 50% interest in GWSI, along with $7.6 million cash, in exchange for an 80% membership interest in 
Water Solutions. As part of the transaction, GWSI was renamed Redtail, became a subsidiary of Water Solutions, and issued 
preferred equity interests to TEI. Among the assets contributed by BNN and the other parties to the transaction were the 
other 50% interest in Redtail and a 100% equity interest in Alpha Reclaim Technology, LLC ("Alpha"), a company which 
sources treated wastewater from municipalities in Texas. Alpha is wholly-owned by Redtail.

Upon closing of the transaction, TEP obtained a controlling financial interest in Water Solutions and accordingly has 
accounted for the transaction as a step acquisition under ASC 805. On the acquisition date, TEP remeasured its previously 
held 50% equity interest in Redtail to its fair value of $11.9 million, recognized a gain of $9.4 million, and consolidated Water
Solutions. The 20% equity interest in Water Solutions held by noncontrolling interests was recorded at its acquisition date fair 
value of $1.4 million. The fair values of the previously held equity interest and the noncontrolling interest were determined 
using a discounted cash flow analysis. These fair value measurements are based on significant inputs that are not observable in 
the market and thus represent fair value measurements categorized within Level 3 of the fair value hierarchy under ASC 820.

At December 31, 2014, the assets acquired and liabilities assumed in the acquisition were recorded at provisional amounts 

based on the preliminary purchase price allocation. During the three months ended June 30, 2015, the preliminary purchase 
price allocation with respect to Water Solutions was finalized with no material adjustments.

On May 20, 2015, TEP acquired an additional 12% equity interest in Water Solutions from NR2, LLC for cash 

consideration of $600,000, which was accounted for as an acquisition of noncontrolling interest. On July 1, 2016, TEP acquired 
the remaining 8% noncontrolling equity interest in Water Solutions and additional interests in certain of Water Solutions' 
subsidiaries from Regency Investments I, LLC and BSEG Water Group LLC for total cash consideration of $6.0 million, which 
was accounted for as an acquisition of noncontrolling interest. Subsequent to the closing of the transaction, our aggregate 
membership interest in Water Solutions is 100%.

5. Related Party Transactions

As a result of our relationship with TD and its affiliates, we have entered into a number of related party transactions. The

following disclosure includes those related party disclosures which are not otherwise disclosed in these notes to our 
consolidated financial statements.

We have no employees. Prior to our IPO, TD, through its wholly-owned subsidiary Tallgrass Operations, LLC ("Tallgrass

Operations"), provided and charged us for direct and indirect costs of services provided to us or incurred on our behalf 
including employee labor costs, information technology services, employee health and retirement benefits, and all other 
expenses necessary or appropriate to the conduct of our business. We recorded these costs on the accrual basis in the period in 
which TD incurred them. On May 17, 2013, in connection with the closing of the IPO, TEP and its general partner entered into 
an Omnibus Agreement with TD and certain of its affiliates, including Tallgrass Operations (the "TEP Omnibus Agreement").

106

The TEP Omnibus Agreement provides that, among other things, TEP will reimburse TD and its affiliates for all expenses they 
incur and payments they make on TEP's behalf, including the costs of employee and director compensation and benefits as well 
as the cost of the provision of certain centralized corporate functions performed by TD, including legal, accounting, cash 
management, insurance administration and claims processing, risk management, health, safety and environmental, information 
technology and human resources in each case to the extent reasonably allocable to TEP.

Due to the cash management agreement discussed in Note 2 – Summary of Significant Accounting Policies, intercompany 

balances at the Predecessor Entities were periodically settled and treated as equity distributions prior to April 1, 2014 for 
Trailblazer and prior to September 1, 2014 for Pony Express. Balances lent to TD under the Pony Express cash management 
agreement effective September 1, 2014 are classified as related party receivables in the consolidated balance sheets. There was 
no interest income from TD recognized for the year ended December 31, 2016. During the years ended December 31, 2015 and 
2014 we recognized interest income from TD of $0.4 million and $1.5 million, respectively, on the receivable balance under the 
Pony Express cash management agreement in effect through December 31, 2015.

Pursuant to the terms of a Purchase and Sale Agreement dated August 1, 2012, TD, through August 31, 2014, reimbursed 
TIGT for all costs TIGT incurred with respect to the Pony Express Abandonment, as defined in Note 17 – Regulatory Matters,
including, but not limited to, development costs, capital costs and related interest costs associated with the construction of 
certain gas facilities necessary to maintain existing natural gas service on the TIGT System (the "Replacement Gas Facilities"). 
The Replacement Gas Facilities are required as part of the Pony Express Abandonment in order for TIGT to continue service to 
existing customers after having sold approximately 433 miles of natural gas pipeline, and associated rights of way and certain 
other equipment, to Pony Express in 2013. For more information, see Note 17 – Regulatory Matters. Any costs incurred by 
TIGT subsequent to August 31, 2014 are reimbursed directly by Pony Express.

TIGT's expenditures for the Replacement Gas Facilities are captured in "Prepayments and other current assets" in the 
consolidated balance sheets as they are incurred and interest is accrued until reimbursement takes place (which is typically 
monthly). During the year ended December 31, 2014 we received proceeds from TD of $69.2 million and incurred expenditures 
of $41.7 million. We recognized a contribution of $27.5 million from TD in our consolidated statement of equity which 
represents the difference between the carrying amount of the Replacement Gas Facilities and the proceeds received from TD.
At December 31, 2016 and 2015, TEP had not incurred any expenditures for the Replacement Gas Facilities that had not been 
reimbursed.

Annual Goodwill Impairment Analysis

We did not elect to apply the qualitative assessment option during our 2016 annual goodwill impairment testing; instead 
we proceeded directly to the two-step quantitative test. In Step 1 of the two-step quantitative test, we compared the fair value of 
each reporting unit with its respective book value, including goodwill, by using an income approach based on a discounted cash 
flow analysis. For the purpose of goodwill impairment testing, goodwill was allocated to our reporting units based on the 
enterprise value of each reporting unit at the date of acquisition. The fair value of each reporting unit was determined on a 
stand-alone basis from the perspective of a market participant and included a sensitivity analysis of the impact of changes in 
various assumptions. This approach required us to make long-term forecasts of future operating results and various other 
assumptions and estimates, the most significant of which are gross margin, operating expenses, general and administrative 
expenses, long-term growth rates and the weighted average cost of capital. The fair value of the reporting units was determined 
using significant unobservable inputs, considered Level 3 under the fair value hierarchy in the Codification. For each reporting 
unit, the results of the Step 1 impairment analysis indicated no potential impairment as the fair value of the reporting units was 
greater than their respective book values. As a result, in accordance with the Codification guidance, Step 2 of the impairment 
analysis was not necessary as part of the annual impairment analysis in 2016.

Investments in Unconsolidated Affiliates

Rockies Express

Our investment in Rockies Express is recorded under the equity method of accounting and reported as "Unconsolidated 

investment" on our consolidated balance sheets. As of May 6, 2016, the difference between the fair value of our investment in 
Rockies Express of $436.0 million and the book value of the underlying net assets of approximately $840.7 million resulted in 
a negative basis difference of approximately $404.7 million. The basis difference was allocated to property, plant and 
equipment and long-term debt based on their respective fair values at the date of acquisition. The amount of the basis difference
allocated to property, plant and equipment is accreted over 35 years, which equates to the 2.86% composite depreciation rate 
utilized by Rockies Express to depreciate the underlying property, plant and equipment. The amount allocated to long-term debt 
is amortized over the remaining life of the various debt facilities. The basis difference at December 31, 2016 was allocated as 
follows:

GWSI

Our investment in GWSI, which owns a fresh water transportation pipeline, was initially recorded under the equity method 

of accounting as we had the ability to exercise significant influence, but not control, over this investment. There was $0.7
million equity in earnings recognized for the year ended December 31, 2014. There was no equity in earnings recognized for 
the years ended December 31, 2015 and 2016. As discussed in Note 4 – Acquisitions, during the year ended December 31, 
2014, TEP acquired a controlling interest in GWSI, which was subsequently renamed Redtail, and consolidated its investment 
in Redtail as of May 13, 2014 accordingly.

10. Risk Management

We occasionally enter into derivative contracts with third parties for the purpose of hedging exposures that accompany our 

normal business activities. Our normal business activities directly and indirectly expose us to risks associated with changes in 
the market price of crude oil and natural gas, among other commodities. For example, the risks associated with changes in the 
market price of crude oil and natural gas include, among others (i) pre-existing or anticipated physical crude oil and natural gas 
sales, (ii) natural gas purchases and (iii) natural gas system use and storage. We have elected not to apply hedge accounting and 
changes in the fair value of all derivative contracts are recorded in earnings in the period in which the change occurs.

(1) As discussed in Note 4 – Acquisitions, in conjunction with our acquisition of an additional 31.3% membership interest 
in Pony Express effective January 1, 2016, TD granted us an 18-month call option covering the 6,518,000 common 
units issued to TD. As of February 1, 2017, no common units remained subject to the call option.

(2) As of December 31, 2016, the fair value shown for natural gas derivative contracts was comprised of derivative 
volumes for short and long natural gas fixed-price swaps totaling 0.3 Bcf and 0.4 Bcf, respectively. As of 
December 31, 2015, there were no natural gas derivative contracts outstanding.

(3) As of December 31, 2016, the fair value shown for crude oil derivative contracts was comprised of derivative 

contracts representing the sale of 125,000 barrels throughout 2017. As of December 31, 2015, there were no crude oil 
derivative contracts outstanding.

Exercise of Call Option

In July 2016 and October 2016, we partially exercised the call option granted by TD in January 2016 as discussed in Note
4 – Acquisitions covering 3,563,146 and 1,251,760 common units, respectively, for cash payments of $151.4 million and $53.2
million, respectively. On February 1, 2017, we exercised the remainder of the call option covering an additional 1,703,094
common units for a cash payment of $72.4 million. These common units were deemed canceled upon the exercise of the call 
option and as of such exercise date were no longer issued and outstanding. As of February 1, 2017, no common units remained 
subject to the call option.

Credit Risk

We have counterparty credit risk as a result of our use of derivative contracts. Counterparties to our crude oil and natural 
gas derivatives consist of major financial institutions. This concentration of counterparties may impact our overall exposure to 
credit risk, either positively or negatively, in that the counterparties may be similarly affected by changes in economic, 
regulatory or other conditions. The counterparty to our call option derivative was TD.

Our over-the-counter swaps are entered into with counterparties outside central trading organizations such as futures, 
options or stock exchanges. These contracts are with financial institutions with investment grade credit ratings. While we enter 
into derivative transactions principally with investment grade counterparties and actively monitor their credit ratings, it is 
nevertheless possible that from time to time losses will result from counterparty credit risk in the future. As of December 31,
2016, the fair value of our crude oil and short natural gas derivative contracts were a liability, resulting in no credit exposure 
from TEP's counterparties as of that date. The maximum potential exposure to credit losses on our long natural gas derivative 
contract at December 31, 2016 was:

As of December 31, 2016 and 2015, we did not have any outstanding letters of credit or cash in margin accounts in support 

of our hedging of commodity price risks associated with the sale of natural gas nor did we have any margin deposits with 
counterparties associated with natural gas contract positions.

Fair Value

Derivative assets and liabilities are measured and reported at fair value. Derivative contracts can be exchange-traded or 
over-the-counter ("OTC"). Exchange-traded derivative contracts typically fall within Level 1 of the fair value hierarchy if they 
are traded in an active market. We value exchange-traded derivative contracts using quoted market prices for identical 
securities.

112

 
 
 
OTC commodity derivatives are valued using models utilizing a variety of inputs including contractual terms and 
commodity and interest rate curves. The selection of a particular model and particular inputs to value an OTC derivative 
contract depends upon the contractual terms of the instrument as well as the availability of pricing information in the market. 
We use similar models to value similar instruments. For OTC derivative contracts that trade in liquid markets, such as generic 
forwards and swaps, model inputs can generally be verified and model selection does not involve significant management 
judgment. Such contracts are typically classified within Level 2 of the fair value hierarchy. The call option granted by TD is 
valued using a Black-Scholes option pricing model. Key inputs to the valuation model include the term of the option, risk free 
rate, the exercise price and current market price, expected volatility and expected distribution yield of the underlying units. The
call option valuation is classified within Level 2 of the fair value hierarchy as the value is based on significant observable 
inputs.

Certain OTC derivative contracts trade in less liquid markets with limited pricing information; as such, the determination 
of fair value for these derivative contracts is inherently more difficult. Such contracts are classified within Level 3 of the fair 
value hierarchy. The valuations of these less liquid OTC derivatives are typically impacted by Level 1 and/or Level 2 inputs 
that can be observed in the market, as well as unobservable Level 3 inputs. Use of a different valuation model or different
valuation input values could produce a significantly different estimate of fair value. However, derivative contracts valued using 
inputs unobservable in active markets are generally not material to our financial statements. When appropriate, valuations are 
adjusted for various factors including credit considerations. Such adjustments are generally based on available market evidence. 
In the absence of such evidence, management's best estimate is used.

The following table summarizes the fair value measurements of our derivative contracts as of December 31, 2016, based 

on the fair value hierarchy established by the Codification:

On September 1, 2016, TEP and Tallgrass Energy Finance Corp. (the "Co-Issuer" and together with TEP, the "Issuers"), the 

Guarantors named therein and U.S. Bank, National Association, as trustee, entered into an Indenture dated September 1, 2016 
(the "Indenture"), pursuant to which the Issuers issued $400 million in aggregate principal amount of 5.50% senior notes due 
2024 (the "2024 Notes"). TEP used the net proceeds of the issuance to repay outstanding borrowings under its existing 
revolving credit facility.

The 2024 Notes are general unsecured senior obligations of the Issuers. The 2024 Notes are unconditionally guaranteed 
jointly and severally on a senior unsecured basis by TEP's existing direct and indirect wholly owned subsidiaries (other than the 
Co-Issuer) and certain of TEP's future subsidiaries (the "Guarantors"). The 2024 Notes rank equal in right of payment with all 
existing and future senior indebtedness of the Issuers, and senior in right of payment to any future subordinated indebtedness of 
the Issuers. The 2024 Notes will mature on September 15, 2024 and interest on the 2024 Notes is payable in cash semi-annually 
in arrears on each March 15 and September 15, commencing March 15, 2017. TEP may redeem the 2024 Notes prior to their 
scheduled maturity at the applicable redemption price set forth in the Indenture, plus accrued and unpaid interest.

The Indenture contains covenants that, among other things, limit TEP's ability and the ability of its restricted subsidiaries 

to: (i) incur, assume or guarantee additional indebtedness or issue preferred units; (ii) create liens to secure indebtedness; 
(iii) pay distributions on equity interests, repurchase equity securities or redeem subordinated securities; (iv) make investments; 
(v) restrict distributions, loans or other asset transfers from TEP's restricted subsidiaries; (vi) consolidate with or merge with or 
into, or sell substantially all of TEP's properties to, another person; (vii) sell or otherwise dispose of assets, including equity 
interests in subsidiaries; and (viii) enter into transactions with affiliates. As of December 31, 2016, we are in compliance with 
the covenants required under the 2024 Notes.

Revolving Credit Facility

On May 17, 2013, in connection with the IPO, TEP entered into a senior secured revolving credit facility with Barclays 
Bank PLC, as administrative agent, and a syndicate of lenders (as amended, "the Credit Agreement"), which will mature on 
May 17, 2018. As of December 31, 2016, the revolving credit facility has a total capacity of $1.75 billion and includes a $75
million sublimit for letters of credit and a $60 million sublimit for swing line loans. The unused portion of the revolving credit 
facility is subject to a commitment fee, which ranges from 0.300% to 0.500%, based on our total leverage ratio. As of 
December 31, 2016, the weighted average interest rate on outstanding borrowings was 2.48%. During the year ended December 
31, 2016, our weighted average effective interest rate, including the interest on outstanding borrowings, commitment fees, and 
amortization of deferred financing costs, was 2.75%.

(1) Effective January 4, 2016, in connection with the acquisition of an additional 31.3% membership interest in Pony 

Express, TEP exercised the committed accordion feature to increase the total capacity of the revolving credit facility to 
$1.5 billion. In connection with the acquisition of a 25% membership interest in Rockies Express, TEP amended the 
revolving credit facility to increase the total capacity to $1.75 billion, which increase became effective May 6, 2016. 

(2) As of February 3, 2017, our outstanding borrowings under the revolving credit facility were approximately $1.130

billion.

The revolving credit facility contains various covenants and restrictive provisions that, among other things, limit or restrict 

our ability (as well as the ability of our restricted subsidiaries) to incur or guarantee additional debt, incur certain liens on 
assets, dispose of assets, make certain distributions (including distributions from available cash, if a default or event of default 
under the credit agreement then exists or would result from making such a distribution), change the nature of our business, 
engage in certain mergers or make certain investments and acquisitions, enter into non-arms-length transactions with affiliates
and designate certain subsidiaries as "Unrestricted Subsidiaries." In addition, we are required to maintain a consolidated 
leverage ratio of not more than 4.75 to 1.00 (which will be increased to 5.25 to 1.00 for certain measurement periods following 
the consummation of certain acquisitions) and a consolidated interest coverage ratio of not less than 2.50 to 1.00. As of 
December 31, 2016, we are in compliance with the covenants required under the revolving credit facility.

The long-term debt borrowed under the revolving credit facility is carried at amortized cost. As of December 31, 2016 and 
2015, the fair value of borrowings under the revolving credit facility approximates the carrying amount of the borrowings using 
a discounted cash flow analysis. The 2024 Notes are carried at amortized cost, net of deferred financing costs. The estimated 
fair value of the 2024 Notes is based upon quoted market prices adjusted for illiquid markets.

We are not aware of any factors that would significantly affect the estimated fair value subsequent to December 31, 2016.

12. Partnership Equity and Distributions

Equity Distribution Agreements

On October 31, 2014, we entered into an equity distribution agreement pursuant to which we may sell from time to time
through a group of managers, as our sales agents, common units representing limited partner interests having an aggregate offering
price of up to $200 million. On May 13, 2015, the amount was subsequently amended to $100.2 million in order to account for
follow-on equity offerings under our S-3 shelf registration statement. On May 17, 2016, we entered into a new equity distribution
agreement allowing for the sale of common units with an aggregate offering price of up to $657.5 million. Sales of common units,
if any, will be made by means of ordinary brokers' transactions, to or through a market maker or directly on or through an electronic
115

 
 
 
 
 
communication network, a "dark pool" or any similar market venue, or as otherwise agreed by the Partnership and one or more
of the managers. We intend to use the net cash proceeds from any sale of the units for general partnership purposes, which may
include, among other things, the Partnership's exercise of the call option with respect to the 6,518,000 common units issued to TD
in connection with the Partnership's acquisition of an additional 31.3% of Pony Express in January 2016, repayment or refinancing
of debt, funding for acquisitions, capital expenditures and additions to working capital.

During the year ended December 31, 2016, we issued and sold 7,696,708 common units with a weighted average sales 
price of $44.46 per unit under our equity distribution agreements for net cash proceeds of approximately $337.7 million (net of 
approximately $4.5 million in commissions and professional service expenses). During the period from January 1, 2017 to 
February 15, 2017, we issued and sold an additional 2,075,546 common units with a weighted average sales price of $48.19 per 
unit under our equity distribution agreements for net cash proceeds of approximately $99.0 million (net of approximately $1.0
million in commissions and professional service expenses). We used the net cash proceeds for general partnership purposes as 
described above. 

During the year ended December 31, 2015, we issued and sold 65,744 common units with a weighted average sales price 

of $45.58 per unit under our equity distribution agreement for net cash proceeds of approximately $3.0 million (net of 
approximately $30,000 in commissions and professional service expenses). We used the net cash proceeds for general 
partnership purposes as described above. 

During the year ended December 31, 2014, we issued and sold 28,625 common units with a weighted average sales price 

of $44.20 per unit under our equity distribution agreements for net cash proceeds of approximately $1.1 million (net of 
approximately $215,000 in commissions and professional service expenses). We used the net cash proceeds for general 
partnership purposes as described above. 

Private Placement

On April 28, 2016, we issued an aggregate of 2,416,987 common units for net cash proceeds of $90 million in a private 
placement transaction to certain funds managed by Tortoise Capital Advisors, L.L.C. The units were subsequently registered 
pursuant to our Form S-3/A (File No. 333-210976) filed with the SEC on May 6, 2016, which became effective May 17, 2016.

Repurchase of Common Units Owned by TD

Following an offer received from TD with respect to common units owned by TD not subject to the call option, we 

repurchased 736,262 common units from TD at an aggregate price of approximately $35.3 million, or $47.99 per common unit, 
on February 1, 2017, which was approved by the conflicts committee of the board of directors of our general partner. These
common units were deemed canceled upon our purchase and as of such transaction date were no longer issued and outstanding.

Tallgrass Development Purchase Program

On February 17, 2016, TEP and Tallgrass Energy GP, LP ("TEGP") announced that the Board of Directors of Tallgrass
Energy Holdings, LLC, the sole member of TEGP's general partner and the general partner of TD, has authorized an equity 
purchase program under which TD may initially purchase up to an aggregate of $100 million of the outstanding Class A shares 
of TEGP or the outstanding common units of TEP. TD may purchase Class A shares or Common Units from time to time on the 
open market or in negotiated purchases. The timing and amounts of any such purchases will be subject to market conditions 
and other factors, and will be in accordance with applicable securities laws and other legal requirements. The purchase plan 
does not obligate TD to acquire any specific number of Class A shares or Common Units and may be discontinued at any time. 
No purchases were made under this program during the year ended December 31, 2016.

Public Offerings

On February 27, 2015, we sold 10,000,000 common units representing limited partner interests in an underwritten public 

offering at a price of $50.82 per unit, or $49.29 per unit net of the underwriter's discount, for net proceeds of approximately 
$492.4 million after deducting the underwriter's discount and offering expenses. We used the net proceeds from the offering to 
fund a portion of the consideration for the acquisition of an additional 33.3% membership interest in Pony Express as discussed 
in Note 4 – Acquisitions. Pursuant to the underwriters' option to purchase additional units, we sold an additional 1,200,000
common units representing limited partner interests to the underwriters at a price of $50.82 per unit, or $49.29 per unit net of 
the underwriter's discount, for net proceeds of approximately $59.3 million after deducting the underwriter's discount and 
offering expenses. We used the net proceeds from this additional purchase of common units to reduce borrowings under our 
revolving credit facility, a portion of which were used to fund the March 2015 acquisition of an additional 33.3% membership 
interest in Pony Express as discussed in Note 4 – Acquisitions.

116

On July 25, 2014, we sold 8,050,000 common units representing limited partner interests in an underwritten public offering

at a price of $41.07 per unit, or $39.74 per unit net of the underwriter's discount, for net proceeds of approximately $319.3
million after deducting the underwriter's discount and offering expenses. We used the net proceeds from the offering to fund a 
portion of the consideration for the acquisition of the initial 33.3% membership interest in Pony Express as discussed in Note 4
– Acquisitions.

Distributions to Holders of Common Units, General Partner Units and Incentive Distribution Rights

Our partnership agreement requires us to distribute our available cash, as defined in the partnership agreement, to 
unitholders of record on the applicable record date within 45 days after the end of each quarter. Our partnership agreement 
provides that available cash, each quarter, is first distributed to the common unitholders and the general partner on a pro rata 
basis until each common unitholder has received $0.2875 per unit, which amount is defined in our partnership agreement as the 
minimum quarterly distribution ("MQD").

Subordinated Units

Under the terms of TEP's partnership agreement and upon the payment of the quarterly cash distribution to unitholders on 
February 13, 2015, the subordination period ended. As a result, the 16,200,000 subordinated units then held by TD converted 
into common units on a one for one basis on February 17, 2015.

General Partner Units

As of December 31, 2016, the general partner owns an approximate 1.14% general partner interest in TEP, represented by 

834,391 general partner units. Under TEP's partnership agreement, the general partner may at any time, but is under no 
obligation to, contribute additional capital to TEP in order to maintain or attain a 2% general partner interest. 

Incentive Distribution Rights

The general partner also owns all of the IDRs. IDRs represent the right to receive an increasing percentage (13%, 23% and 

48%) of quarterly distributions of available cash from operating surplus after the MQD and each target distribution level has 
been achieved. The general partner may transfer these rights separately from its general partner interest, subject to restrictions 
in our partnership agreement. 

The following discussion related to incentive distributions assumes that our general partner holds a 2% general partner 

interest and continues to own all of the IDRs.

117

 
 
 
 
 
 
If for any quarter:

• We have distributed available cash from operating surplus to all of the common unitholders (and during the 

subordination period, to the subordinated unitholders) in an amount equal to the MQD for each outstanding unit for 
such quarter; and

• We have distributed available cash from operating surplus on outstanding common units in an amount necessary to 

eliminate any cumulative arrearages in the payment of the MQD to common unitholders;

then, we will distribute additional available cash from operating surplus for that quarter among the unitholders and the 

general partner in the following manner:

•

•

•

•

first, 98% to all unitholders, pro rata, and 2% to our general partner, until each unitholder receives a total of $0.3048
per unit for that quarter (the "first target distribution");

second, 85% to all unitholders, pro rata, and 15% to our general partner, until each unitholder receives a total of 
$0.3536 per unit for that quarter (the "second target distribution");

third, 75% to all unitholders, pro rata, and 25% to our general partner, until each unitholder receives a total of $0.4313
per unit for that quarter (the "third target distribution"); and

thereafter, 50% to all unitholders, pro rata, and 50% to our general partner.

Definition of Available Cash

Available cash generally means, for any quarter, all cash and cash equivalents on hand at the end of that quarter:

•

less the amount of cash reserves established by our general partner to:

provide for the proper conduct of our business (including reserves for future capital expenditures, for 
anticipated future credit needs subsequent to that quarter, for legal matters and for refunds of collected rates 
reasonably likely to be refunded as a result of a settlement or hearing related to FERC rate proceedings);

comply with applicable law or regulation, or any of our debt instruments or other agreements; or

provide funds for distributions to unitholders and to our general partner for any one or more of the next four 
quarters (provided that our general partner may not establish cash reserves for distributions if the effect of the 
establishment of such reserves will prevent us from distributing the MQD on all common units and any 
cumulative arrearages on such common units for the current quarter);

•

plus, if our general partner so determines, all or any portion of the cash on hand on the date of distribution of available 
cash for the quarter, including cash on hand resulting from working capital borrowings made subsequent to the end of 
such quarter.

Other Contributions and Distributions

During the year ended December 31, 2016, TEP was deemed to have made noncash capital distributions of $280.0 million

and $34.0 million to the general partner, which represent the excess purchase price over the carrying value of the additional 
31.3% membership interest in Pony Express acquired effective January 1, 2016 and the derecognition of a portion of the 
derivative asset associated with the partial exercise of the call option, respectively. See Note 4 – Acquisitions for additional 
information regarding these transactions. During the year ended December 31, 2016, TEP also received contributions of $17.9
million from TD to indemnify TEP for costs associated with Trailblazer's Pipeline Integrity Management Program, as discussed 
in Note 18 – Legal and Environmental Matters, and recognized contributions from and distributions to noncontrolling interests 
of $9.3 million, and $6.5 million, respectively, which primarily consisted of activity associated with TD's 2% noncontrolling 
interest in Pony Express.

During the year ended December 31, 2015, TEP was deemed to have made a noncash capital distribution of $324.3

million to the general partner, which represents the excess purchase price over the carrying value of the additional 33.3%
membership interest in Pony Express acquired effective March 1, 2015. See Note 4 – Acquisitions for additional information 
regarding the transaction. We also recognized contributions from noncontrolling interests of $110.1 million, which consisted 
primarily of contributions from TD to Pony Express to fund construction of the lateral in Northeast Colorado, and distributions 
to noncontrolling interests of $69.5 million, which consisted primarily of distributions from Pony Express to TD.

118

During the year ended December 31, 2014, we received net contributions of $312.1 million, $27.5 million, and $5.4
million from the Predecessor Entities, TD, and noncontrolling interests, respectively. Net contributions of 312.1 million from 
the Predecessor Entities is composed of net contributions of $612.1 million relating to the cash management agreements with 
TD, as well as a cash distribution of $300 million of the proceeds from the issuance of the preferred membership interest to 
TEP from Pony Express to TD pursuant to the Pony Express Contribution and Sale Agreement. As discussed in Note 2 –
 Summary of Significant Accounting Policies, prior to April 1, 2014 for Trailblazer and prior to September 1, 2014 for Pony 
Express, the net amount of transfers for loans made each day through the centralized cash management system with TD, less 
reimbursement payments under the agency agreement described in Note 5 – Related Party Transactions, was recognized as net 
equity contributions or distributions during that time period. There were no equity contributions or distributions made to TD
subsequent to Trailblazer's acquisition by TEP on April 1, 2014 or the acquisition of Pony Express effective September 1, 2014. 
The 27.5 million contribution from TD represents the difference between the carrying amount of the Replacement Gas 
Facilities and the proceeds received from TD, as discussed in Note 5 – Related Party Transactions. The $5.4
million contribution from noncontrolling interests represents the cash contributed to Pony Express from TD to fund the 
quarterly preference payment to TEP as discussed in Note 4 – Acquisitions. During the year ended December 31, 2014, Pony 
Express made a distribution of $5.4 million to TD, which was settled via the Pony Express cash management agreement.

During the year ended December 31, 2014, TEP was deemed to have made a noncash, net capital distribution of $72.9
million to the general partner, which represents the excess purchase price over the carrying value of the Trailblazer net assets 
acquired on April 1, 2014. Also during the year ended December 31, 2014, TEP was deemed to have made a capital distribution 
of $8.7 million to the general partner, which represents the excess purchase price, consisting of $27 million in cash and limited 
partner common units valued at $3.0 million issued directly to TD, over the net book value of the 1.9585% membership interest 
in Pony Express transferred from TD to TEP in accordance with the Pony Express Contribution and Sale Agreement. See Note
4 – Acquisitions for additional information regarding the Trailblazer and Pony Express acquisitions.

13. Commitments & Contingent Liabilities

Leases

Rent expense under operating leases and right of way agreements totaled approximately $30.1 million, $25.8 million, and 

$4.7 million for the years ended December 31, 2016, 2015, and 2014, respectively.

Operating leases and service contracts consist of leases for crude oil storage as well as office space and equipment.

Pony Express entered into a lease agreement with Deeprock on November 7, 2012 for the use by Pony Express of storage 

capacity at the Deeprock tank storage facility near Cushing, Oklahoma. The lease has a five-year term which commenced on 
October 7, 2014. Pony Express made upfront payments totaling $10.9 million, of which $4.6 million was paid in 2013 and $6.3
million was paid in 2014. The upfront payments are recorded as "Deferred charges and other assets" on the accompanying 
consolidated balance sheets and will be amortized over the lease term. Pony Express has the right to extend the term of the 
lease for additional periods of five or two years, not to exceed a total of 20 years from when the lease commences. Future 
minimum rental commitments in the table above assume renewal of the Deeprock lease for the full 20-year term as the storage 
capacity at Deeprock is integral to the operations of the Pony Express System and renewal of the lease is reasonably assured as 
a result. 

119

On August 26, 2014, Pony Express entered into a lease agreement with Sterling for the use by Pony Express of storage 
capacity at the Sterling tank storage facility in northeast Colorado. The lease has a five-year term which commenced on May 1, 
2015. Pony Express has the right to extend the term of the lease for additional periods of five years, not to exceed a total of 20
years from the commencement of the lease agreement. Future minimum rental commitments in the table above assume renewal 
of the Sterling lease for the full 20-year term as the storage capacity at Sterling is integral to the operations of the lateral in 
Northeast Colorado and renewal of the lease is reasonably assured as a result. As discussed in Note 21 – Subsequent Events,
effective January 1, 2017 we acquired 100% of the issued and outstanding membership interests in Tallgrass Terminals, LLC 
("Terminals"), which owns the Sterling Terminal.

Capital Expenditures

We had committed approximately $6.5 million for the future purchase of property, plant and equipment at December 31,

2016.

Other Purchase Obligations

Other purchase obligations primarily represent costs associated with Western's freshwater delivery and produced water 
gathering and disposal systems acquired in December 2015. Actual costs associated with these contracts totaled approximately 
$1.4 million and $4,000 for the years ended December 31, 2016 and 2015, respectively.

At December 31, 2016, future minimum commitments under long-term, non-cancelable contracts for other purchase

14. Net Income per Limited Partner Unit

The Partnership's net income is allocated to the general partner and the limited partners, including the holders of the 

subordinated units, in accordance with their respective ownership percentages, after giving effect to incentive distributions paid 
to the general partner. Basic and diluted net income per limited partner unit is calculated by dividing limited partners' interest in 
net income, less general partner incentive distributions, by the weighted average number of outstanding limited partner units 
during the period. As discussed in Note 12 – Partnership Equity and Distributions, the subordinated units were converted to 
common units effective February 17, 2015.

We compute earnings per unit using the two-class method for Master Limited Partnerships as prescribed in the FASB
guidance. The two-class method requires that securities that meet the definition of a participating security be considered for 
inclusion in the computation of basic earnings per unit. Under the two-class method, earnings per unit is calculated as if all of 
the earnings for the period were distributed under the terms of the partnership agreement, regardless of whether the general 
partner has discretion over the amount of distributions to be made in any particular period, whether those earnings would 
actually be distributed during a particular period from an economic or practical perspective, or whether the general partner has 
other legal or contractual limitations on its ability to pay distributions that would prevent it from distributing all of the earnings 
for a particular period.

We calculate net income available to limited partners based on the distributions pertaining to the current period's net 
income. After adjusting for the appropriate period's distributions, the remaining undistributed earnings or excess distributions 
over earnings, if any, are allocated to the general partner and limited partners in accordance with the contractual terms of the 
partnership agreement and as further prescribed in the FASB guidance under the two-class method.

The two-class method does not impact our overall net income or other financial results; however, in periods in which 
aggregate net income exceeds our aggregate distributions for such period, it will have the impact of reducing net income per 
limited partner unit. This result occurs as a larger portion of our aggregate earnings, as if distributed, is allocated to the 
incentive distribution rights (which are currently held by our general partner), even though we make distributions on the basis 
of available cash and not earnings. In periods in which our aggregate net income does not exceed our aggregate distributions 
for such period, the two-class method does not have any impact on our calculation of earnings per limited partner unit.

120

Basic earnings per unit is computed by dividing net earnings attributable to unitholders by the weighted average number of 

units outstanding during each period. Diluted earnings per unit reflects the potential dilution of common equivalent units that 
could occur if equity participation units are converted into common units.

All net income or loss from Trailblazer prior to its acquisition on April 1, 2014 and Pony Express prior to its acquisition 

effective September 1, 2014 is allocated to predecessor operations in the table below. Historical earnings of transferred 
businesses for periods prior to the date of those common control drop-down transactions are solely those of the general partner,
and therefore we have appropriately excluded any allocation to the limited partner units when determining net income available 
to common and subordinated unitholders. We present the financial results of any transferred business prior to the drop down 
transaction date in the line item "Predecessor operations interest in net income" in the table below.

The following table illustrates the Partnership's calculation of net income per common and subordinated unit for the years

ended December 31, 2016, 2015 and 2014:

15. Major Customers and Concentration of Credit Risk

During the year ended December 31, 2016 two non-affiliated customers, Continental Resources, Inc. ("Continental 
Resources") and Shell Trading (US) Company ("Shell"), accounted for $97.8 million (16%) and $76.2 million (13%) of our 
total operating revenues, respectively. During the year ended December 31, 2015 two non-affiliated customers, Continental 
Resources and Shell, accounted for $84.5 million (16%) and $78.6 million (15%) of our total operating revenues, respectively.
In 2016 and 2015, revenues from Continental Resources were earned in our Crude Oil Transportation & Logistics segment, 
while revenues from Shell were earned in our Crude Oil Transportation & Logistics, Processing & Logistics, and Natural Gas 
Transportation & Logistics segments. During the year ended December 31, 2014 one non-affiliated customer, Phillips 66, 
accounted for $113.6 million (31%) of our total operating revenues. All of the Phillips 66 revenues were earned in our 
Processing & Logistics segment.

For the year ended December 31, 2016, the percentage of segment revenues from the top ten non-affiliated customers for 

each segment was as follows:

Crude Oil Transportation & Logistics...............................

Natural Gas Transportation & Logistics ...........................

We attempt to mitigate credit risk by seeking collateral or financial guarantees and letters of credit from customers with 
specific credit concerns. In support of credit extended to certain customers, we had received prepayments of $4.9 million and 
$4.7 million at December 31, 2016 and 2015, respectively, included in the caption "Other current liabilities" in the 
accompanying consolidated balance sheets.

16. Equity-Based Compensation

Long-term Incentive Plan

Effective May 13, 2013, the general partner adopted a Long-term Incentive Plan ("LTIP") pursuant to which awards in the 
form of unrestricted units, restricted units, equity participation units, options, unit appreciation rights or distribution equivalent 
rights may be granted to employees, consultants, and directors of the general partner and its affiliates who perform services for 
or on behalf of TEP or its affiliates, including TD. Vesting and forfeiture requirements are at the discretion of the board of 
directors of the general partner (the "Board") and can be delegated to a committee of the Board.

The LTIP limits the number of units that may be delivered pursuant to vested awards to 10,000,000 common units. 
Common units canceled, forfeited or withheld to satisfy exercise prices or tax withholding obligations will be available for 
delivery pursuant to other awards. The plan is administered by the Board or a committee thereof, which is referred to as the 
plan administrator.

The Board may generally terminate or amend the LTIP at any time with respect to any units for which a grant has not yet 

been made. The Board also has the right to alter or amend the LTIP or any part of the plan from time to time, including 
increasing the number of units that may be granted subject to the requirements of the exchange upon which the common units 
are listed at that time. However, no change in any outstanding grant may be made that would materially reduce the rights or 
benefits of the participant without the consent of the participant. The LTIP will expire on the earliest of (i) the date common 
units are no longer available under the plan for grants, (ii) termination of the plan by the Board or (iii) May 13, 2023.

Equity Participation Units

On June 26, 2013, TEP's general partner approved the grant of up to 1.5 million equity participation units ("EPUs") for 
issuance to employees and 177,500 EPUs to certain Section 16 officers under the LTIP. The EPU grants under the LTIP are 
measured at their grant date fair value. The EPUs granted are non-participating with respect to distributions, therefore the grant 
date fair value is discounted from the grant date fair value of TEP's common units for the present value of the expected future 
distributions during the vesting period. Total equity-based compensation cost related to the EPU grants was approximately $7.9
million, $9.3 million, and $10.2 million for the years ended December 31, 2016, 2015, and 2014, respectively. Of the total 
compensation cost, $5.8 million, $5.1 million, and $5.1 million for the years ended December 31, 2016, 2015, and 2014,
respectively, were recognized as compensation expense at TEP and the remainder was allocated to TD. As of December 31,
2016, $12.0 million of total compensation cost related to non-vested EPUs is expected to be recognized over a weighted 
average period of 2.2 years, a portion of which will be charged to TD.

The following table summarizes the changes in the EPUs outstanding for the years ended December 31, 2016, 2015 and 

2014:

17. Regulatory Matters

There are currently no proceedings challenging the currently effective transportation rates of Pony Express, Rockies 

Express, Tallgrass Interstate Gas Transmission, LLC ("TIGT") or Trailblazer Pipeline Company LLC ("Trailblazer").
Regulators, as well as shippers, do have rights, under circumstances prescribed by applicable law, to challenge the rates that we 
charge at our regulated entities. Further, applicable law governing service by Pony Express allows parties having standing to 
file complaints in regard to existing tariff rates and provisions. If the complaint is not resolved, the FERC may conduct a 
hearing and order a crude oil pipeline like the Pony Express System to make reparations going back for up to two years prior to 
the date on which a complaint was filed if a rate is found to be unjust and unreasonable. We can provide no assurance that 
current rates will remain unchallenged. Any successful challenge could have a material, adverse effect on our future earnings 
and cash flows. 

Pony Express

On September 19, 2014 Pony Express filed with the FERC to adopt a tariff for initial local non-contract rates as well as 
initial Rules and Regulations in accordance with the Interstate Commerce Act to be effective starting on October 1, 2014. Local 
Contract Tariff rates were filed with the FERC on October 29, 2014 to be effective starting November 1, 2014. Joint Contract 
Tariff rates for oil received into the Pony Express pipeline system from the Belle Fourche Pipeline were filed on October 16, 
2014 to be effective starting November 1, 2014. Joint Contract Tariff rates for oil received into the Pony Express System from 
Hiland Pipeline Company were filed on February 27, 2015 and effective April 1, 2015.

On May 18, 2015, Pony Express filed with the FERC to implement tariff contract rates for Pony Express' newly 

constructed lateral in Northeast Colorado effective June 1, 2015. 

On May 29, 2015, tariff filings were made with the FERC in Docket No. IS15-492-000 to increase the Pony Express local 
contract rates for service from the Guernsey origin, and for local non-contract rates from all origins, by amounts reflecting the 
FERC annual index adjustment of approximately 4.6% effective July 1, 2015. A tariff filing was also made in Docket No. 
IS15-493-000 on that date to increase joint tariff contract rates for service on Pony Express by approximately 4.6% effective
July 1, 2015. 

On October 29, 2015, Pony Express made a tariff filing with the FERC in Docket No. IS16-42-000 to increase the contract 

rates under its Local Pipeline Tariff for transportation from receipt points on its lateral in Northeast Colorado to various 
delivery points in Oklahoma, by an amount reflecting the most recent FERC annual index adjustment of approximately 4.6%
effective December 1, 2015.

On May 25, 2016, Pony Express made a tariff filing with the FERC in Docket No. IS16-326-000 to update its non-contract 
rates under its Local Pipeline Tariff for local non-contract rates from all origins, by an amount reflecting the most recent FERC 
annual index adjustment of approximately 0.9799 effective July 1, 2016, which resulted in a reduction of the Pony Express 
non-contract rates of 2.01%.

Rockies Express

Petition for Declaratory Order – FERC Docket No. RP13-969-000 

In June 2013, in Docket No. RP13-969-000, Rockies Express filed with the FERC a Petition for Declaratory Order which 
sought a ruling that the "most favored nations" or "MFN" provisions contained in Rockies Express' negotiated rate agreements 
("NRAs") with its Foundation and Anchor Shippers would not prevent Rockies Express from providing firm transportation 
service at rates lower than Foundation and Anchor Shippers' rates that (1) have an east-to-west primary path; (2) are for a term 
of one year or longer; and (3) are limited to service in one rate zone and therefore do not utilize all of the same facilities or rate 
zones as the service provided pursuant to the Foundation and Anchor Shipper NRAs. 

In September 2014, the FERC accepted amended contracts with three shippers holding MFN rights on Rockies Express, 
which reflect the terms of settlements between these shippers and Rockies Express. The settlements provide additional clarity 
with respect to the applicability of the settling shippers' MFN rights, sharing by Rockies Express of certain transportation 
revenues, and the withdrawal of the settling shippers from the Petition for Declaratory Order proceeding. Prior to December 
2015, only one shipper with current MFN rights was still a party to the proceeding.

2015 Annual FERC Fuel Tracking Filings - Docket No. RP15-584-000 

On February 27, 2015, Rockies Express made its annual fuel tracker filing with a proposed effective date of April 1, 2015 

in Docket No. RP15-584-000. This filing incorporated the revised fuel and lost and unaccounted-for and power cost tracker 
mechanisms filed in Docket No. RP14-1003. The FERC issued an order accepting the filing on March 26, 2015 and on April 9,
2015, accepted an errata to the February 27, 2015 filing reflecting a corrected rate for the Cheyenne Booster rate (PCT
Reimbursement Charge).

123

Seneca Lateral Facilities Conversion – FERC Docket No. CP15-102-000 

On March 2, 2015 in Docket No. CP15-102-000, Rockies Express filed with the FERC an application for (1) authorization 

to convert certain existing and operating pipeline and compression facilities located in Noble and Monroe Counties, Ohio 
(Seneca Lateral Facilities described in Docket Nos. CP13-539-000 and CP14-194-000) from Natural Gas Policy Act of 1978 
Section 311 authority to NGA Section 7 jurisdiction, and (2) issuance of a certificate of public convenience and necessity 
authorizing Rockies Express to operate and maintain the Seneca Lateral Facilities. On April 7, 2016, the FERC issued a 
Certificate to Rockies Express granting its requested authorizations and on June 1, 2016 Rockies Express commenced NGA
service on the Seneca Lateral.

Rockies Express Zone 3 Capacity Enhancement Project – FERC Docket No. CP15-137-000

On March 31, 2015 in Docket No. CP15-137-000, Rockies Express filed with the FERC an application for authorization to 
construct and operate (1) three new mainline compressor stations located in Pickaway and Fayette Counties, Ohio and Decatur 
County, Indiana; (2) additional compressors at an existing compressor station in Muskingum County, Ohio; and (3) certain 
ancillary facilities. The proposed facilities will increase the Rockies Express Zone 3 east-to-west mainline capacity by 0.8 Bcf/
d. Pursuant to the FERC's obligations under the National Environmental Policy Act, FERC staff issued an Environmental 
Assessment for the project on August 31, 2015. On February 25, 2016, the FERC issued a Certificate of Public Convenience 
and Necessity authorizing Rockies Express to proceed with the project. On March 14, 2016, Rockies Express commenced 
construction of the project facilities. The project was placed in-service for the 0.8 Bcf/d on January 6, 2017. 

2016 Annual and Interim FERC Fuel Tracking Filings - Docket Nos. RP16-702 and RP17-240

On March 1, 2016, Rockies Express made its annual fuel tracker filing with a proposed effective date of April 1, 2016 in 

Docket No. RP16-702. The FERC issued an order accepting the filing on March 25, 2016. On December 1, 2016, Rockies 
Express made an interim fuel tracker filing with a proposed effective date of January 1, 2017 in Docket No. RP17-240. The
FERC issued an order accepting the filing on December 29, 2016. The filing reflected a corrected rate for a previous 
inadvertent error made in the allocation of Overthrust, Echo Springs, and Wamsutter fuel between non-expansion and 
expansion volumes during the period from July 2014 through July 2016.

Electric Power Charge Clarification - Docket No. RP17-285

On December 21, 2016, in Docket No. RP17-285, Rockies Express proposed certain revisions to the General Terms and 

Conditions of its tariff to clarify that the electric power costs associated with the operation of gas coolers installed in 
association with the Zone 3 Capacity Enhancement Project (i.e. at both electric and gas powered stations), will be included in 
the Power Cost Tracker. Several shippers submitted comments on the proposal. The FERC issued an order on January 19, 2017 
accepting the proposed revisions permitting the recovery of electric power costs from the operation of both gas and electric 
powered compressor stations, subject to certain clarifications.

TIGT

Pony Express Abandonment – FERC Docket CP12-495

On August 6, 2012, TIGT filed an application to: (1) abandon for FERC purposes approximately 433 miles of mainline 
natural gas pipeline facilities, along with associated rights of way and other related equipment (collectively, the "Pony Express 
Assets"), and the natural gas service therefrom, by transferring those assets to Pony Express, which subsequently converted the 
Pony Express Assets into crude oil pipeline facilities; and (2) construct and operate certain replacement-type facilities 
necessary to continue service to existing natural gas firm transportation customers following the conversion, which we refer to 
as the Replacement Gas Facilities. This project is referred to as the "Pony Express Abandonment." The FERC abandonment 
does not constitute an abandonment for accounting purposes. Pursuant to the terms of the Purchase and Sale Agreement filed 
with the FERC and cited by the FERC in approving the Pony Express Abandonment, Pony Express is required to reimburse 
TIGT for the net book value of the Pony Express Assets plus other TIGT incurred costs required to construct the Replacement 
Gas Facilities and to arrange substitute gas transportation services to certain TIGT shippers.

The Pony Express Abandonment and completion of the Pony Express Project by Pony Express re-deployed existing 

pipeline assets to meet the growing market need to transport crude oil while at the same time continuing to operate TIGT's
natural gas transportation facilities to meet all current and expected needs of its natural gas customers. By a FERC order issued 
September 12, 2013, TIGT was granted authorization to abandon the Pony Express Assets and construct the Replacement Gas 
Facilities. On October 7, 2013 TIGT commenced the mobilization of personnel and equipment for the construction of the 
Replacement Gas Facilities necessary to complete the Pony Express Abandonment to continue service to existing TIGT
customers. In December 2013, TIGT removed the Pony Express Assets from gas service and sold those assets to Pony Express. 
On May 1, 2014, TIGT commenced commercial service through all of the Replacement Gas Facilities, with the exception of 
Units 3 and 4 at the Tescott Compressor Station. Service through Units 3 and 4 at the Tescott Compressor Station commenced 
on May 30, 2014.

124

General Rate Case Filing - FERC Docket RP16-137

On October 30, 2015, TIGT filed a general rate case with the FERC pursuant to Section 4 of the National Gas Act
("NGA"). The rate case proposed a general system-wide increase in the maximum tariff rates for all firm and interruptible 
services offered by TIGT. In addition, TIGT proposed certain changes to the transportation rate design of its system to replace 
the current rate zone structure with a single "postage stamp" rate. TIGT also proposed new incremental charges, including (i) a 
charge for deliveries made to points without certain electronic flow measurement equipment, and (ii) a Cost Recovery 
Mechanism ("CRM") charge to completely or partially reimburse TIGT for certain expenses and costs it incurs to comply with 
anticipated new PHMSA and EPA regulations. TIGT also proposed to replace its fixed fuel and lost and unaccounted for 
("FL&U") charge with a FL&U tracker that would compensate TIGT for its actual FL&U expenses and adjust each year to 
reflect the previous period's under/over collection and the forecasted FL&U expense for the upcoming period. TIGT also 
proposed to implement a power cost tracker to recover the actual power costs incurred by TIGT to power its compressors. 
Finally, TIGT proposed certain revisions to its FERC Gas Tariff addressing a number of other rate and non-rate matters. Under 
the NGA and the FERC's regulations, TIGT's shippers and other interested parties, including the FERC's Trial Staff, have a 
right to challenge any aspect of TIGT's rate case filing. Accordingly, numerous TIGT customers protested aspects of TIGT's
NGA Section 4 rate filing.

On November 30, 2015, the FERC issued an order accepting and suspending the proposed rates and a majority of the 
proposed tariff records to be effective upon motion May 1, 2016, subject to refund, certain modifications to TIGT's proposed 
CRM charge, and the outcome of an evidentiary hearing before a FERC Administrative Law Judge (the "TIGT Suspension 
Order"). In the TIGT Suspension Order, the FERC also accepted two tariff records related to force majeure events and 
reservation charge crediting to be effective December 1, 2015, subject to certain modifications. On December 21, 2015, TIGT
made a compliance filing with the FERC to modify TIGT's proposed CRM charge and update the tariff records related to force
majeure events and reservation charge crediting as directed by the FERC in the TIGT Suspension Order. No comments or 
protests were filed in response to the compliance filing and the FERC accepted the compliance filing on February 1, 2016. On 
March 31, 2016, the FERC issued an order denying certain rehearing requests pertaining to the proposed CRM charge and 
removed from hearing the non-rate issues related to proposed pro forma tariff records, placing the non-rate issues under a 
separate review process, and allowing interveners further opportunity to comment on the pro forma tariff. TIGT and certain 
intervenors have since filed additional information and/or comments with respect to the proposed pro forma tariff. On February 
3, 2017, the FERC accepted TIGT’s pro forma tariff records, subject to conditions, and directed TIGT to file the actual tariff
records within 30 days.

On June 8, 2016, TIGT filed an Offer of Settlement (the "TIGT Rate Case Settlement") with the FERC, which resolved all 
issues set for hearing. On July 14, 2016, the presiding Administrative Law Judge certified the TIGT Rate Case Settlement to the 
FERC, finding that settlement is uncontested, presents no issues of first impression, has no FERC policy implications, and 
appears to be just, reasonable and in the public interest. On November 2, 2016, the FERC issued an order approving the TIGT
Rate Case Settlement, finding that it appears to be fair and reasonable and in the public interest. The FERC also directed TIGT
to file revised tariff records to implement the TIGT Rate Case Settlement, which TIGT filed, and the FERC subsequently 
approved on December 23, 2016. The November 2, 2016 order also terminated all matters in the TIGT rate case, apart from the 
non-rate issues related to the pro forma tariff which remain pending before the FERC. Per the terms of the TIGT Rate Case 
Settlement, TIGT is required to file a new general rate case on May 1, 2019 (provided that such rate case is not pre-empted by a 
pre-filing settlement), and no Supporting/Non-Contesting Participant, as defined in the TIGT Rate Case Settlement, is 
permitted to, inter alia, file to change the settlement rates or any other provisions set forth in the TIGT Rate Case Settlement 
prior to May 1, 2019.

Trailblazer

2013 Rate Case Filing - Docket No. RP13-1031 

On January 22, 2014, Trailblazer, the FERC's Trial Staff, and the active parties in the pipeline's general rate case finalized a 

settlement in principle resolving the pending rate issues, including: (i) establishing transportation rates, as well as fuel and lost 
and unaccounted for charges; (ii) providing a limited profit sharing arrangement for certain revenues earned from interruptible 
and short-term firm transport; and (iii) setting the minimum and maximum time that can elapse before Trailblazer's next rate 
case at the FERC. Trailblazer filed a motion with the FERC's Chief Administrative Law Judge to accept the settlement rates on 
an interim basis ("Interim Rates") while the participants finalized a definitive settlement. The Chief Administrative Law Judge 
accepted the Interim Rates effective February 1, 2014. On February 24, 2014, Trailblazer filed an uncontested offer of 
settlement ("Stipulation and Agreement") among active party shippers. The Stipulation and Agreement established the Interim 
Rates as final settlement rates effective February 1, 2014, subject to the issuance of refunds to certain shippers for January 2014 
transportation services and revised fuel and lost and unaccounted for rates, effective July 1, 2014. On March 11, 2014, the 
Presiding Administrative Law Judge certified the Stipulation and Agreement. On May 29, 2014, the FERC approved the 
Stipulation and Agreement. On June 30, 2014, Trailblazer filed tariff sheets to implement the Stipulation and Agreement
effective July 1, 2014. Estimated refunds were reserved from revenues recorded in January 2014. On July 1, 2014, Trailblazer
125

submitted refunds to its customers for amounts collected in excess of amounts that would have been collected under the 
Settlement Rates, with interest, and on July 18, 2014, filed a report of refunds with the FERC. The FERC issued orders 
accepting the tariff sheets with the requested effective date of July 1, 2014 and accepting the refund report filing on July 25, 
2014 and August 7, 2014, respectively. Per the terms of the Stipulation and Agreement, Trailblazer is required to file a new rate 
case with rates to be effective by January 1, 2019.

2015 Annual Fuel Tracker Filing - Docket No. RP15-841-000 

On April 1, 2015, Trailblazer made its annual fuel tracker filing with a proposed effective date of May 1, 2015 in Docket 

No. RP15-841-000. This filing incorporates the revised fuel tracker and power cost tracker mechanisms agreed to in the 
Stipulation and Agreement, which resolves all outstanding issues related to Trailblazer fuel recoveries. The FERC approved this 
filing on April 23, 2015.

2016 Annual Fuel Tracker Filing – Docket Nos. RP16-814-000 and RP16-814-001

On April 1, 2016, Trailblazer made its annual fuel tracker filing with a proposed effective date of May 1, 2016 in Docket 

No. RP16-814-000. The FERC accepted this filing on April 18, 2016. On May 19, 2016, Trailblazer filed its refund report 
associated with the April 1, 2016 annual fuel tracker filing, which the FERC accepted on July 11, 2016. On September 7, 2016, 
Trailblazer filed an adjustment to its April 1, 2016 filing in Docket No. RP16-814-001, which the FERC accepted on October 3, 
2016. Trailblazer filed a corresponding refund report on October 14, 2016, which the FERC accepted on November 16, 2016.

18. Legal and Environmental Matters

Legal

In addition to the matters discussed below, we are a defendant in various lawsuits arising from the day-to-day operations of 

our business. Although no assurance can be given, we believe, based on our experiences to date, that the ultimate resolution of 
such routine items will not have a material adverse impact on our business, financial position, results of operations, or cash 
flows.

We have evaluated claims in accordance with the accounting guidance for contingencies that we deem both probable and 

reasonably estimable and, accordingly, have recorded no reserve for legal claims as of December 31, 2016 and 2015.

Rockies Express

Mineral Management Service Lawsuit 

On June 30, 2009, Rockies Express filed claims against Mineral Management Service, a former unit of the U.S. 

Department of Interior (collectively "Interior") for breach of its contractual obligation to sign transportation service agreements 
for pipeline capacity that it had agreed to take on Rockies Express. The Civilian Board of Contract Appeals ("CBCA") 
conducted a trial and ruled that Interior was liable for breach of contract, but limited the damages Interior was required to pay.
On September 13, 2013, the United States Court of Appeals for the Federal Circuit issued a decision affirming that Interior was 
liable for its breach of contract, but reversing the CBCA's decision to limit damages. The case was remanded to the CBCA for 
the purpose of calculating damages at a hearing. On May 20, 2016, Rockies Express and Interior agreed to resolve the claims in 
this matter in exchange for a $65 million cash payment to Rockies Express. Interior paid the amount due Rockies Express on 
June 23, 2016.

Ultra Resources

In early 2016, Ultra Resources, Inc. ("Ultra") defaulted on its firm transportation service agreement for approximately 0.2

Bcf/d through November 11, 2019. In late March 2016, Rockies Express terminated Ultra's service agreement. On April 14, 
2016, Rockies Express filed a lawsuit against Ultra for breach of contract and damages in Harris County, Texas, seeking 
approximately $303 million in damages and other relief. On April 29, 2016, Ultra and certain of its debtor affiliates filed for 
protection under Chapter 11 of the United States Bankruptcy Code in United States Bankruptcy Court for the Southern District 
of Texas, which operated as a stay of the Harris County state court proceeding.

On January 12, 2017, Rockies Express and Ultra entered into an agreement to settle Rockies Express' approximately $303

million claim against Ultra's bankruptcy estate. The settlement agreement includes Ultra's agreement to: (i) make a cash 
payment to Rockies Express of $150 million in accordance with the plan of reorganization, but no later than October 30, 2017; 
and (ii) enter a new, seven-year firm transportation agreement with Rockies Express commencing December 1, 2019, for west-
to-east service of 0.2 Bcf/d at a rate of approximately $0.37, or approximately $26.8 million annually. The settlement is part of 
Ultra's Chapter 11 reorganization plan, which must be submitted to the U.S. Bankruptcy Court for approval.

126

Michels Corporation 

On June 17, 2014, Michels Corporation ("Michels") filed a complaint and request for relief against Rockies Express in the 

Court of Common Pleas, Monroe County, Ohio, as a result of work performed by Michels to construct the Seneca Lateral 
Pipeline in Ohio. Michels sought unspecified damages from Rockies Express and asserted claims of breach of contract, 
negligent misrepresentation, unjust enrichment and quantum meruit. Michels also filed notices of Mechanic's Liens in Monroe 
and Noble Counties, asserting $24.2 million as the amount due.

On February 2, 2017, Rockies Express and Michels entered into a binding settlement agreement to resolve the claims 
brought by Michels in exchange for a $10 million cash payment by Rockies Express. The cash payment will be paid promptly 
after entering into the definitive agreement with respect to the settlement.

Environmental, Health and Safety

We are subject to a variety of federal, state and local laws that regulate permitted activities relating to air and water quality,

waste disposal, and other environmental matters. We believe that compliance with these laws will not have a material adverse 
impact on our business, cash flows, financial position or results of operations. However, there can be no assurances that future 
events, such as changes in existing laws, the promulgation of new laws, or the development of new facts or conditions will not 
cause us to incur significant costs. We had environmental reserves of $4.0 million and $4.8 million at December 31, 2016 and 
2015, respectively.

TMID

Casper Plant, EPA Notice of Violation

In August 2011, the EPA and the Wyoming Department of Environmental Quality ("WDEQ") conducted an inspection of 
the Leak Detection and Repair ("LDAR") Program at the Casper Gas Plant in Wyoming. In September 2011, TMID received a 
letter from the EPA alleging violations of the Standards of Performance of Equipment Leaks for Onshore Natural Gas 
Processing Plant requirements under the Clean Air Act. TMID received a letter from the EPA concerning settlement of this 
matter in April 2013 and received additional settlement communications from the EPA and Department of Justice beginning in 
July 2014. Settlement negotiations are continuing, including the expected inclusion of TIGT as a party to any possible 
settlement as a result of TIGT owning a compressor that is located adjacent to the Casper Gas Plant site.

Casper Mystery Bridge Superfund Site

The Casper Gas Plant is part of the Mystery Bridge Road/U.S. Highway 20 Superfund Site also known as Casper Mystery 
Bridge Superfund Site. Remediation work at the Casper Gas Plant has been completed and we have requested that the portion 
of the site attributable to us be delisted from the National Priorities List.

Casper Gas Plant

On November 25, 2014, WDEQ issued a Notice of Violation for violations of Part 60 Subpart OOOO related to the 
Depropanizer project (wv-14388, issued 7/9/13) in Docket No. 5506-14. TMID had discussed the issues in a meeting with 
WDEQ in Cheyenne on November 17, 2014, and submitted a disclosure on November 20, 2014 detailing the regulatory issues 
and potential violations. The project triggered a modification of Subpart OOOO for the entire plant. The project equipment as 
well as plant equipment subjected to Subpart OOOO was not monitored timely, and initial notification was not made timely.
Settlement negotiations with WDEQ are currently ongoing.

Trailblazer

Pipeline Integrity Management Program

Trailblazer is currently operating at less than its current maximum allowable operating pressure ("MAOP"), public notice 

of which was first provided in June 2014. As a result of smart tool surveys in 2014, Trailblazer has identified 
approximately 25 - 35 miles of pipe that will likely need to be repaired or replaced in order for the pipeline to operate at its 
MAOP of 1,000 pounds per square inch across all segments of the Trailblazer Pipeline. Such repair or replacement will likely 
occur over a period of years, depending upon the remediation and repair plan implemented by Trailblazer. Segments of the 
Trailblazer Pipeline that require full replacement could cost as much as $2.7 million per mile and repair costs on sections of the 
pipeline that do not require full replacement are expected to be less on a per mile basis. The current pressure reduction is not 
expected to prevent Trailblazer from fulfilling its firm service obligations at existing subscription levels and to date it has not 
had a material adverse financial impact on us.

127

With respect to the approximately 25 - 35 miles of pipe that has been identified, Trailblazer completed 32 excavation digs 
in 2015 at an aggregate cost of approximately $1.3 million. During 2016, Trailblazer completed additional excavation digs and 
replaced approximately 8 miles of pipe at an aggregate cost of approximately $19.0 million. Trailblazer is currently exploring 
all possible cost recovery options to recover such out of pocket costs, including recovery through a general rate increase, 
negotiated rate agreements with its customers, or other FERC-approved recovery mechanisms. 

In connection with our acquisition of the Trailblazer Pipeline, TD agreed to contractually indemnify TEP for any out of 
pocket costs incurred between April 1, 2014 and April 1, 2017 related to repairing or remediating the Trailblazer Pipeline, to the 
extent that such actions are necessitated by external corrosion caused by the pipeline's disbonded Hi-Melt CTE coating. The
contractual indemnity provided by TD is capped at $20 million and is subject to an annual $1.5 million deductible. In 
connection with the 2016 repairs and remediation on the Trailblazer Pipeline, TEP has received $17.9 million from TD pursuant 
to the contractual indemnity.

Pony Express

Pipeline Integrity

In connection with certain crack tool runs on the Pony Express System completed in 2015 and 2016, Pony Express 
completed approximately $9.8 million of remediation for anomalies identified on the Pony Express System associated with 
portions of the pipeline converted from natural gas to crude oil service, and expects to complete additional remediation in 2017 
on the Pony Express System of approximately $9 million.

Terminals

System Failures

In January 2017, 10,000 bbls of crude oil were released at the Sterling Terminal, which was acquired as part of the 

Terminals acquisition on January 1, 2017 as discussed in Note 21 – Subsequent Events. Initial reviews indicate that the release 
was restricted to the containment area located at the Sterling Terminal and was the result of a defective roof drain system on a 
storage tank. To date, approximately 9,000 bbls have been recovered. We believe that the total cost to remediate the release will 
be less than $500,000.

19. Reportable Segments

Our operations are located in the United States. We are organized into three reportable segments: (1) Crude Oil 

Transportation & Logistics, (2) Natural Gas Transportation & Logistics, and (3) Processing & Logistics.

Crude Oil Transportation & Logistics

The Crude Oil Transportation & Logistics segment is engaged in the ownership and operation of the Pony Express System, 
which is a FERC-regulated crude oil pipeline serving the Bakken Shale, Denver-Julesburg and Powder River Basins, and other 
nearby oil producing basins. The mainline portion of the Pony Express System was placed in service in October 2014. The
Pony Express System also includes a lateral pipeline in Northeast Colorado, which interconnects with the Pony Express System 
just east of Sterling, Colorado and was placed in service in the second quarter of 2015. 

Natural Gas Transportation & Logistics

The Natural Gas Transportation & Logistics segment is engaged in the ownership and operation of FERC-regulated 
interstate natural gas pipelines and integrated natural gas storage facilities that provide services to on-system customers (such 
as third-party LDCs), industrial users and other shippers. The Natural Gas Transportation & Logistics segment includes our 
25% membership interest in Rockies Express effective May 6, 2016, as discussed in Note 4 – Acquisitions

Processing & Logistics

The Processing & Logistics segment is engaged in the ownership and operation of natural gas processing, treating and 
fractionation facilities that produce NGLs and residue gas that is sold in local wholesale markets or delivered into pipelines for 
transportation to additional end markets, as well as water business services provided primarily to the oil and gas exploration 
and production industry and the transportation of NGLs.

Corporate and Other

Corporate and Other includes corporate overhead costs that are not directly associated with the operations of our reportable 

segments, such as interest and fees associated with our revolving credit facility, public company costs, and equity-based 
compensation expense.

128

These segments are monitored separately by management for performance and are consistent with internal financial 
reporting. These segments have been identified based on the differing products and services, regulatory environment and the 
expertise required for their respective operations.

We consider Adjusted EBITDA our primary segment performance measure as we believe it is the most meaningful 

measure to assess our financial condition and results of operations as a public entity. We define Adjusted EBITDA, a non-
GAAP measure, as net income excluding the impact of interest, income taxes, depreciation and amortization, non-cash income 
or loss related to derivative instruments, non-cash long-term compensation expense, impairment losses, gains or losses on asset 
or business disposals or acquisitions, gains or losses on the repurchase, redemption or early retirement of debt, and earnings 
from unconsolidated investments, but including the impact of distributions from unconsolidated investments.

21. Subsequent Events

Acquisition of Tallgrass Terminals, LLC and Tallgrass NatGas Operator, LLC

Effective January 1, 2017, we acquired 100% of the issued and outstanding membership interests in Tallgrass Terminals,

LLC ("Terminals") and 100% of the issued and outstanding membership interests in Tallgrass NatGas Operator, LLC 
("NatGas") from TD for total cash consideration of $140 million.

Terminals owns several fully operational assets providing storage capacity and additional injection points for the Pony 
Express System, including the Sterling Terminal near Sterling, Colorado, the Buckingham Terminal in northeast Colorado, and 
a 20% interest in the Deeprock Development Terminal in Cushing, Oklahoma. Terminals also owns projects currently under 
development, including acreage in Cushing, Oklahoma and Guernsey, Wyoming which is under development to provide 
additional storage capacity and other potential opportunities.

NatGas is the operator of the Rockies Express Pipeline and receives a fee from Rockies Express as compensation for its 

services.

Ultra Settlement

In January 2017, Rockies Express reached an agreement to settle its breach of contract claim against Ultra Resources, Inc. 

See Note 18 – Legal and Environmental Matters for further discussion.

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosures

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15(b) of the Exchange Act, we have evaluated, under the supervision and with the participation of 

our management, including our principal executive officer and principal financial officer, the effectiveness of the design and 
operation 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 report. Our disclosure controls and procedures are designed to provide reasonable 
assurance that the information required to be disclosed by us 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 the SEC, and such 
information is accumulated and communicated to our management, including our principal executive officer and principal 
financial officer, as appropriate, to allow timely decisions regarding required disclosure. Based upon their evaluation of those 
controls and procedures performed as of December 31, 2016, our principal executive officer and principal financial officer
concluded that our disclosure controls and procedures were effective at the reasonable assurance level.

Management's Report on Internal Control over Financial Reporting 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as 

defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Our internal control over financial reporting is a process 
designed under the supervision of our principal executive officer and principal financial officer to provide reasonable assurance 
regarding the reliability of financial reporting and the preparation of our financial statements for external purposes in 
accordance with generally accepted accounting principles.

As of December 31, 2016, management assessed the effectiveness of our internal control over financial reporting based on 

the criteria for effective internal control over financial reporting established in the 2013 "Internal Control - Integrated 
Framework," issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment 
and those criteria, management determined that we maintained effective internal control over financial reporting as of 
December 31, 2016.

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.

Our independent registered public accounting firm, PricewaterhouseCoopers LLP, audited the effectiveness of our internal 

control over financial reporting as of December 31, 2016, as stated in their report included in Item 8.—Financial Statements 
and Supplementary Data of this Annual Report. 

Changes in Internal Control over Financial Reporting

There have not been any changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) 

and 15d-15(f) under the Exchange Act) during the quarter ended December 31, 2016 that have materially affected, or are 
reasonably likely to materially affect, our internal control over financial reporting.

Item 9B. Other Information

None.

132

Item 10. Directors, Executive Officers and Corporate Governance

PART III

We are a limited partnership and have no officers or directors. Unless otherwise indicated, references to our officers and 

directors in Items 10 through 14 of this Annual Report refer to the officers and directors of our general partner.

Management of Tallgrass Energy Partners, LP

Our general partner manages our operations and activities on our behalf through its directors and officers. Our general 
partner is not elected by our unitholders and will not be subject to re-election in the future. Directors of our general partner 
oversee our operations. Unitholders are not entitled to elect the directors of our general partner or directly or indirectly 
participate in our management or operations. Our general partner will be liable, as general partner, for all of our debts (to the 
extent not paid from our assets), except for indebtedness or other obligations that are made expressly non-recourse to it. Our 
general partner therefore may cause us to incur indebtedness or other obligations that are non-recourse to it.

Tallgrass Equity is the sole member of our general partner and has the right to appoint all of the officers and directors of 

our general partner. TEGP owns a 36.94% membership interest in, and is the managing member of, Tallgrass Equity. TEGP
Management is TEGP's general partner. Tallgrass Energy Holdings is the sole member of TEGP Management and has the right 
to appoint the entire board of directors of TEGP Management, including its independent directors. 

Tallgrass Energy Holdings effectively controls our business and affairs through the exercise of its rights as the party that 
controls Tallgrass Equity, including its right to appoint members to the board of directors of our general partner. EMG, Kelso 
and Tallgrass KC, LLC (an entity owned by certain members of our management, "Tallgrass KC") own, in the aggregate, 
approximately 100% of the outstanding membership interests in Tallgrass Energy Holdings. All of the executive officers and 
certain of the directors of our general partner are also officers and/or directors of TEGP Management and Tallgrass Energy
Holdings.

As of December 31, 2016, the board of directors of our general partner had nine directors, four of whom the board has 
determined meet the independence standards established by the NYSE and the Exchange Act. The four independent directors 
are Jeffrey A. Ball (for purposes of audit committee participation only), Terrance D. Towner, Roy N. Cook, and Jeffrey R. 
Armstrong. The NYSE does not require a publicly-traded limited partnership like ours to have a majority of independent 
directors on the board of directors of its general partner or to establish a compensation or a nominating and corporate 
governance committee. However, our general partner is required to have an audit committee of at least three members, and all 
of its members are required to meet the independence and experience standards established by the NYSE and the Exchange 
Act. As of December 31, 2016, the audit committee of the board of directors of our general partner had three members, each of 
whom meet the independence standards established by the NYSE and the Exchange Act.

In evaluating director candidates, Tallgrass Energy Holdings assesses whether a candidate possesses the integrity,
judgment, knowledge, experience, skill and expertise that are likely to enhance the board's ability to manage and direct our 
affairs and business, including, when applicable, to enhance the ability of committees of the board to fulfill their duties.

All of the executive officers of our general partner are also officers of Tallgrass Equity, TEGP Management, and Tallgrass

Energy Holdings. Our officers will devote such portion of their business time to our business and affairs as they deem 
reasonably required to manage and conduct our operations. Neither our general partner nor Tallgrass Development and its 
affiliates currently receive any management fee or other compensation in connection with the management or operation of our 
business. However, our partnership agreement requires us to reimburse our general partner and its affiliates for all expenses 
incurred and payments made on our behalf in connection with managing our business. These expenses include salary, bonus, 
incentive compensation and other amounts paid to persons who perform services for us or on our behalf and expenses allocated 
to our general partner by its affiliates. Our partnership agreement and the TEP Omnibus Agreement each provides that our 
general partner will determine in good faith the expenses that are allocable to us. In addition, the TEP Omnibus Agreement
requires us to reimburse Tallgrass Energy Holdings and its affiliates for expenses they incur in providing general and 
administrative services to us. Neither our partnership agreement nor the TEP Omnibus Agreement limits the amount of 
expenses for which our general partner or Tallgrass Energy Holdings and its affiliates may be reimbursed.

Audit Committee

The board of directors of our general partner has a standing audit committee which is currently comprised of three 

directors, Jeffrey A. Ball, Terrance D. Towner, and Jeffrey R. Armstrong. Each audit committee member has past experience in 
accounting or related financial management experience. The board has determined that all of our audit committee members are 
independent under Section 303A.02 of the NYSE listing standards and Rule 10A-3 of the Securities Exchange Act of 1934, as 
amended. In making the independence determination, the board considered the requirements of the NYSE, the SEC and our 
Code of Business Conduct and Ethics. Among other factors, the board considered current or previous employment with us, our 
auditors or their affiliates by the director or his immediate family members, ownership of our voting securities and other 
material relationships with us. The audit committee has adopted a charter, which has been ratified and approved by the board of 
directors.

Jeffrey A. Ball has been designated by the board as the audit committee's financial expert meeting the requirements 
promulgated by the SEC and set forth in Item 407(d) of Regulation S-K of the Securities Exchange Act of 1934, as amended, 
based upon his education and employment experience as more fully detailed in Mr. Ball's biography set forth above. Mr. Ball

Conflicts Committee

Our general partner may, from time to time, have a conflicts committee to which the board of directors will appoint at least 

two independent directors and which may be asked to review specific matters that the board believes may involve conflicts of 
interest between our general partner and its affiliates, on one hand, and us and our unitholders, on the other. The conflicts 
committee will determine if the resolution of any conflict of interest referred to it by our general partner is in the best interests 
of our partnership. There is no requirement that our general partner seek the approval of the conflicts committee for the 
resolution of any conflict. The members of the conflicts committee may not be officers or employees of our general partner or 
directors, officers or employees of its affiliates, may not hold an ownership interest in our general partner or its affiliates other 
than shares or awards under any long-term incentive plan, equity compensation plan or similar plan implemented by the general 
partner or us, and must meet the independence and experience standards established by the NYSE and the Exchange Act to 
serve on an audit committee of a board of directors. The conflicts committee currently consists of three independent directors, 
Roy N. Cook, Terrance D. Towner, and Jeffrey R. Armstrong, with Mr. Cook currently acting as the Chairman.

Any matters approved by the conflicts committee will be conclusively deemed to have been approved by all of our 

partners, and shall not constitute a breach by our general partner of any duties it may owe us or our unitholders. Any unitholder 
challenging any matter approved by the conflicts committee will have the burden of proving that the members of the conflicts 
committee did not subjectively believe that the matter was in the best interests of our partnership. Moreover, any acts taken or 
137

omitted to be taken in reliance upon the advice or opinions of experts such as legal counsel, accountants, appraisers, 
management consultants and investment bankers, where our general partner (or any members of the board of directors of our 
general partner including any member of the conflicts committee) reasonably believes the advice or opinion to be within such 
person's professional or expert competence, shall be conclusively presumed to have been done or omitted in good faith.

Corporate Governance Guidelines and Code of Business Conduct and Ethics 

Our general partner has adopted Corporate Governance Guidelines and a Code of Business Conduct and Ethics applicable 

to all of our employees, officers and directors with regard to Partnership-related activities. The Corporate Governance 
Guidelines and the Code of Business Ethics incorporate guidelines designed to deter wrongdoing and to promote honest and 
ethical conduct and compliance with applicable laws and regulations. They also incorporate expectations of our employees that 
enable us to provide accurate and timely disclosure in our filings with the SEC and other public communications. A copy of the 
Corporate Governance Guidelines and the Code of Business Conduct and Ethics are available to any person, free of charge, at 
our website at www.tallgrassenergy.com.

Partner at: Tallgrass Energy Partners, LP, 4200 W. 115th Street, Suite 350, Leawood, Kansas 66211.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires members of our general partner's board of directors, executive officers of our 

general partner, and persons who own more than 10% of a registered class of our equity securities, to file with the SEC, and 
any exchange or other system on which such securities are traded or quoted, initial reports of ownership and reports of changes 
in ownership of our common units and other equity securities. Officers, directors and greater than 10% unitholders are required 
by the SEC's regulations to furnish to us and any exchange or other system on which such securities are traded or quoted with 
copies of all Section 16(a) forms they file with the SEC.

Based solely upon a review of Forms 3, 4 and 5, and amendments thereto, we know of no director, officer, or beneficial 
owner of more than 10% of any class of our equity securities registered pursuant to Section 12 of the Exchange Act that failed 
to file timely any reports required to be furnished during 2016 pursuant to Section 16(a) of the Exchange Act, except that on 
September 15, 2016, Tallgrass Energy Holdings, Tallgrass Development and Tallgrass Operations filed a Form 4 due July 25,

Item 11. Executive Compensation

Compensation Discussion and Analysis

 Executive Summary and Background

We and our general partner were formed in Delaware in February 2013. We do not directly employ any of the persons 

responsible for managing our business. Our business is managed and operated by the directors and executive officers of our 
general partner. All employees, including our Named Executive Officers (as defined in "Summary Compensation Table"
below), are employed by an affiliate of our general partner, Tallgrass Management, LLC ("Tallgrass Management"). 

Compensation of our Named Executive Officers is set and approved by the board of directors of our general partner and by 

the board of managers of Tallgrass Energy Holdings, which indirectly controls our general partner. Tallgrass Energy Holdings 
owns 100% of Tallgrass Management and 100% of the general partner of TEGP. As of February 15, 2017, TEGP owns a 
36.94% membership interest in and is managing member of Tallgrass Equity, which owns a 27.41% limited partner interest in 
us and, through its ownership of all of the membership interests in our general partner, our general partner interest and our 
incentive distribution rights. Tallgrass Energy Holdings also serves as the general partner of Tallgrass Development. We
reimburse Tallgrass Development for all salaries, benefits and other compensation expenses for employees of Tallgrass
Management (including the Named Executive Officers) to the extent such employees provide services to us pursuant to an 
allocation agreed upon between our general partner and Tallgrass Development under the terms of the TEP Omnibus 
Agreement. Other than the employment agreement with our Chief Executive Officer, David G. Dehaemers, Jr., none of our 
Named Executive Officers has entered into any employment agreements with Tallgrass Management, our general partner or any 
other affiliate of TEP.

138

 Philosophy and Objectives

Since our initial public offering in May 2013, we have employed a compensation philosophy that emphasizes pay for 

performance and places the majority of each Named Executive Officer's compensation at risk. We believe our pay-for-
performance approach aligns the interests of our Named Executive Officers with that of our unitholders, and at the same time 
enables us to maintain a lower level of recurring compensation costs in the event our operating or financial performance is 
below expectations. We design our executive compensation to attract and retain individuals with the background and skills 
necessary to successfully execute our business model in a demanding environment, to motivate those individuals to reach near-
term and long-term goals in a way that aligns their interest with that of our unitholders, and to reward success in reaching such 
goals.

We use three primary elements of compensation to fulfill that design: salary, cash bonus and long-term equity incentive 

awards. Cash bonuses and long-term equity incentives (as opposed to salary) generally represent the performance driven 
elements. They are also flexible in application and can be tailored to meet our objectives. The determination of specific 
individuals' cash bonuses is based on their relative contribution to achieving or exceeding relative near-term company goals and 
the determination of specific individuals' long-term incentive equity awards is based on their actual and anticipated contribution 
to longer term performance objectives. The primary long-term measure of our performance is our ability to increase quarterly 
distributions to our unitholders while maintaining safe operations and long-term stable cash flow and financial health. 

We do not maintain a defined benefit or pension plan for our Named Executive Officers as we believe such plans primarily 

reward longevity and not performance. We provide a basic benefits package generally to all employees, which includes a 401
(k) plan and health, disability and life insurance. 

Elements of Compensation

Salary. We benchmark our salary amounts to comparable companies in our industry. We believe our salaries are generally 

competitive with the universe of similarly situated master limited partnerships, but are moderate relative to energy industry 
competitors for people with similar roles and responsibilities.

Cash Bonuses. Our cash bonuses are annual discretionary bonuses in which all of our current Named Executive Officers

potentially participate.

Long-Term Incentive Awards. Our Named Executive Officers receive grants under both the TEP and TEGP LTIP (as 
defined below). TEP and TEGP share the same primary long-term performance measure of increasing quarterly distributions 
while maintaining safe operations and long-term stable cash flow and financial health. As a result of TEGP’s controlling 
membership interest in Tallgrass Equity and indirect ownership of a 27.41% limited partnership interest in TEP, all of TEP’s
general partner interest and all of TEP’s incentive distribution rights, failing to achieve that performance standard at TEP would 
be detrimental to TEGP, and vice versa. We therefore believe granting our Named Executive Officers equity participation units 
under the TEP LTIP and equity participation shares under the TEGP LTIP appropriately incentivizes our Named Executive 
Officers to seek stable distribution growth at both entities. We expect equity participation unit awards under the TEP LTIP will 
be the primary long-term equity incentive provided to our Named Executive Officers, and that grants of equity participation 
shares will be made pursuant to the TEGP LTIP on a more limited basis.

Long-Term Incentive Awards of TEP. Effective May 13, 2013, our general partner adopted a Long-Term Incentive Plan 
("TEP LTIP") pursuant to which awards based on common units of TEP in the form of restricted units, equity participation 
units, unit options, unit appreciation rights, distribution equivalent rights and unit awards may be granted to employees, 
consultants, and directors of TEP GP and its affiliates who perform services for or on behalf of TEP or its affiliates, including 
Tallgrass Development. Historically, we have used equity participation unit grants issued under the TEP LTIP to encourage and 
reward timely achievement of certain events or TEP distribution levels and align the long-term interests of our Named 
Executive Officers with those of our unitholders. An equity participation unit is the right to receive, upon the satisfaction of 
vesting criteria specified in the grant, a common unit. 

The vesting conditions applicable to our outstanding equity participation unit awards can generally be divided into three 

categories. The first category of awards was granted between June 2013 and September 2014 with vesting of such awards 
contingent upon the Pony Express System going into commercial service, which occurred in October 2014. Thus, the awards in 
this category will vest as long as the employee satisfies the continuing service requirement set forth in the applicable award 
agreement. Generally, one-third of the awards in this category vested on May 13, 2015 and the remaining two-thirds will vest 
on May 13, 2017. All of our Named Executive Officers other than Mr. Dehaemers were granted equity participation unit awards 
in this category.

139

The second category of our equity participation unit awards were granted between August 2015 and September 2015 with 

vesting occurring in two parts. One-half vests on the later to occur of the first date on which we have paid a regular quarterly 
distribution of at least $0.6875 on each outstanding common unit (the "TEP Distribution Achievement Date") or May 13, 2018, 
and the other half vesting on the later to occur of the TEP Distribution Achievement Date or May 13, 2019. The TEP
Distribution Achievement Date occurred on May 13, 2016, thus the awards in this category will vest as long as the employee 
satisfies the continuing service requirement set forth in the applicable award agreement. Mr. Jones and Mr. Watkins are the only 
Named Executive Officers that were granted equity participation units in this second category.

The third category of our equity participation unit awards were granted in November 2016 and will vest on November 1, 

2019 as long as the employee satisfies the continuing service requirement set forth in the applicable award agreement. Mr.
Jones and Mr. Watkins are the only Named Executive Officers that were granted equity participation units in this third category.

Long-Term Incentive Awards of TEGP. Our Named Executive Officers also participate in the Long-Term Incentive Plan 
established by the general partner of TEGP effective May 1, 2015 ("TEGP LTIP"). Pursuant to the TEGP LTIP, awards based 
on Class A shares of TEGP in the form of restricted shares, equity participation shares, options, share appreciation rights, 
distribution equivalent rights and share awards may be granted to employees, consultants, and directors of Tallgrass
Management and its affiliates who perform services for or on behalf of TEGP or its affiliates, including TEP and Tallgrass
Development (such awards, collectively with the awards under the TEP LTIP, the "LTIP Awards"). An equity participation share 
is the right to receive, upon the satisfaction of vesting criteria specified in the grant, a TEGP Class A share. 

In 2015, grants of equity participation shares were made under TEGP LTIP, including a grant made to Mr. Jones and to Mr.
Watkins, who are thus far the only Named Executive Officers to receive a grant under the TEGP LTIP. The terms of the awards 
to Mr. Jones and Mr. Watkins each stipulate that the equity participation shares will generally vest upon the later of the first 
date on which TEGP pays a regular quarterly distribution of at least $0.35 on each outstanding Class A share (the "TEGP
Distribution Date") or May 12, 2019. If TEGP has not distributed at least $0.35 on each outstanding Class A Share for any full 
quarter ending on or before May 12, 2020, the unvested equity participation shares will expire and no vesting will occur. Mr.
Jones and Mr. Watkins must also remain in continuous employment through the vesting date.

Relation of Compensation Elements to Compensation Objectives

Our compensation program is designed to motivate, reward and retain our Named Executive Officers. Cash bonuses serve 

as a near-term motivation and reward for achieving positive short-term results, such as meeting specified distribution growth 
and other financial guidance targets. Longer-term retention is facilitated by the requirement for continued employment or 
service for specified time periods in order for LTIP Awards to fully vest. The level of cash bonuses and LTIP Awards reflect the 
moderate salary profile of our Named Executive Officers and the weighting towards performance based, at-risk compensation. 

We strive to focus on performance-based compensation elements in an attempt to create a performance-driven environment 

in which our Named Executive Officers are (i) motivated to perform over both the short-term and the long-term, 
(ii) appropriately rewarded for their services and (iii) encouraged to remain with us even after meeting long-term performance 
goals. We believe our compensation philosophy as implemented by application of the three primary compensation elements 
(i) aligns the interests of our Named Executive Officers with our unitholders, (ii) positions us to achieve our business goals, and 
(iii) effectively encourages the exercise of sound judgment and risk-taking that is conducive to creating and sustaining long-
term value. We believe the processes we employ to apply the elements of compensation (as discussed in more detail below) 
provide an adequate level of oversight with respect to the degree of risk being taken by management to achieve short-term and 
long-term performance goals. See "Relation of Compensation Policies and Practices to Risk Management."

We believe our compensation program has been instrumental in our achievement of stated objectives. The first category of 

awards was granted between June 2013 and September 2015 with vesting contingent, in part, upon the Pony Express System 
going into commercial service, which occurred on October 2014. As noted above, two-thirds of those awards still remain 
subject to the continuing service requirement set forth in the applicable award agreement, which has supported our goal of 
long-term retention of Named Executive Officers. Additionally, one of the primary measures of our performance is our ability 
to enhance the ability of our assets to generate distributable cash flow that we can use to increase quarterly distributions to our 
unitholders. In the period since our initial public offering through December 31, 2016, our annual distribution per common unit 
has grown at a compound annual rate of 35%. This distribution growth has, in part, supported our decision to pay cash bonuses 
to our Named Executive Officers over that period. 

Application of Compensation Elements

Salary. We do not make systematic annual adjustments to the salaries of our Named Executive Officers. We do, however,

make salary adjustments as necessary to ensure that our salaries remain competitive in the industry marketplace. 

140

Annual Discretionary Cash Bonuses. Annual discretionary bonuses are determined based on our performance relative to 

our annual budget, our distribution growth targets, and other quantitative and qualitative goals established each year. Such 
annual objectives are discussed and reviewed with the board of directors periodically during the year and then again in 
conjunction with the review and authorization of the annual budget and this annual report. 

At the end of each year, the CEO, with assistance from other members of executive management, performs a quantitative 

and qualitative assessment of our performance relative to our goals. Key quantitative measures include Adjusted EBITDA, 
distributable cash flow, distribution coverage, and growth in the annualized quarterly distribution level per common unit 
relative to annual growth targets. We also compare our market performance relative to our MLP peers and major indices. Our 
primary performance metric is our ability to generate increasing and sustainable cash distributions to our unitholders. 
Accordingly, although net income and net income per unit are monitored to highlight inconsistencies with our primary 
performance metrics, we do not consider net income and net income per unit to be key performance measures. Executive 
management's analysis of our performance examines our accomplishments, shortfalls and overall performance against 
opportunity, taking into account controllable and non-controllable factors encountered during the year.

After the annual company-level performance analysis is completed by our CEO and other members of executive 

management, that same group, along with personnel from our human resources department, considers cash bonuses and salary 
adjustments for our employees, including our Named Executive Officers. There are no set formulas for determining salary 
adjustments or annual discretionary bonuses for our Named Executive Officers. Factors considered by executive management 
in determining the level of salary adjustment and bonus in general include (i) whether or not we achieved any goals established 
for the year and any notable shortfalls relative to expectations; (ii) the level of difficulty associated with achieving any such 
objectives based on the opportunities and challenges encountered during the year; (iii) current year operating and financial 
performance relative to both public guidance and prior year's performance; (iv) significant transactions or accomplishments for 
the period not included in the goals for the year; (v) our prospects at the end of the year with respect to future growth and 
performance; and (vi) our positioning at the end of the year with respect to our targeted credit profile. The CEO and other 
members of executive management take these factors into consideration, as well as the relative contributions of each of our 
Named Executive Officers to the year's performance, in developing recommendations for Named Executive Officer bonus 
amounts and salary adjustments.

These recommendations for discretionary bonus amounts and salary adjustments for our Named Executive Officers are 
presented to the board of directors of our general partner and the board of managers of Tallgrass Energy Holdings, adjusted as 
appropriate, and then formally approved by those boards. In several historical instances, the CEO has requested that his bonus 
amount be reduced, or eliminated.

Long-Term Incentive Awards. We do not make systematic annual grants of LTIP Awards to our Named Executive Officers.

We have historically attempted to time the granting of LTIP Awards such that the creation of new long-term incentives 
coincides with the satisfaction of vesting criteria under existing awards. We have not formally decided on a recurring grant 
cycle for future grants, but we intend for future grants to provide a balance between a meaningful retention period for us and a 
visible, reasonable, growth-oriented reward for the executive officer. Under existing LTIP Awards, achievement of performance 
targets does not shorten the minimum service period requirement. 

Application in 2016

At the beginning of 2016, we established the following financial performance objectives for 2016:

•

•

•

Distributable Cash Flow of $285 - 305 million for the year ended December 31, 2016; 

Distribution coverage of 1.05 - 1.15x for the year ended December 31, 2016; and

Growth of approximately 20% in our annualized distribution rate for the calendar year 2016.

We achieved all of these goals:

•

•

Our Distributable Cash Flow for the year ended December 31, 2016 was approximately $408.5 million;

Our distribution coverage for the year ended December 31, 2016 was 1.27x; and

• We grew our annualized distribution rate during calendar year 2016 by 27.3%.

Additionally, our internal qualitative goals included (a) advancing multi-year programs and initiatives and preparing the 
organization for future growth, and (b) continuing to promote a culture of safety and environmental responsibility throughout 
the organization. We achieved several accomplishments with respect to these qualitative goals, including:

•

The acquisition by us of a 25% membership interest in Rockies Express from a unit of Sempra U.S. Gas and Power in 
May 2016; 

141

•

•

The acquisition by us of 100% of the membership interests in Terminals and 100% of the membership interests in 
NatGas from Tallgrass Development effective January 1, 2017; and

Substantially completing the Rockies Express Zone 3 Capacity Enhancement Project during 2016, for an additional 
0.8 Bcf/d of east-to-west Zone 3 mainline capacity.

For 2016, the elements of compensation were applied as described below.

Salary. In 2016, we did not implement material salary increases for our Named Executive Officers.

Cash Bonuses. Based on the CEO's annual performance review and the individual performance of each of our Named 

Executive Officers, the board of directors of our general partner approved the annual bonuses for our Named Executive 
Officers reflected in the Summary Compensation Table and notes thereto. Such amounts take into account performance relative 
to our 2016 goals; the level of difficulty associated with achieving such objectives; our relative positioning at the end of the 
year with respect to future growth and performance; the significant transactions or accomplishments for the period not included 
in the goals for the year; and our positioning at the end of the year with respect to our targeted credit profile. The board of 
directors of our general partner also considered, on a subjective basis, how well the executive officer performed his or her 
duties during the year.

Long-Term Incentive Awards. Pursuant to the TEP LTIP, Mr. Jones and Mr. Watkins each received a grant of 2,000 equity 
participation units in 2016. No equity participation shares were granted to a Named Executive Officer under the TEGP LTIP in 
2016. As noted below, we believe the substantial direct and indirect equity interests held by our management team, including 
our Named Executive Officers, in TEP, TEGP, Tallgrass Equity and Tallgrass Energy Holdings aligns their interests with those 
of our unitholders, and is taken into account when considering the level of equity incentives in TEP and TEGP granted to our 
Named Executive Officers under our compensation programs.

Other Compensation Related Matters

Equity Ownership. Although we encourage our Named Executive Officers to acquire and retain ownership in TEP common 

units and TEGP Class A shares, we do not require our Named Executive Officers to maintain a specified equity ownership 
level. Our policies, including our Insider Trading Policy, strongly discourage our Named Executive Officers from using puts, 
calls or options to hedge the economic risk of their ownership in TEP or TEGP. Based on the closing price of TEP’s common 
units and TEGP’s Class A shares on February 15, 2017, the value of the combined equity ownership of our Named Executive 
Officers discussed below was significantly greater than their combined aggregate salaries and bonuses for 2016. We believe 
that the substantial direct and indirect equity interests held by our management team in TEGP, Tallgrass Energy Holdings and 
TEP further aligns their interests with those of our unitholders, and is taken into account when considering the level of equity 
incentives in TEP and TEGP granted to our Named Executive Officers under our compensation programs.

Equity Ownership in TEP. Our Named Executive Officers collectively own substantial equity in TEP. As of February 15, 
2017, our Named Executive Officers directly owned, in the aggregate, 370,101 of our common units (excluding any unvested 
LTIP Awards).

Equity Ownership in TEGP and Tallgrass Energy Holdings. Some of our Named Executive Officers directly own Class A

shares in TEGP and some of our Named Executive Officers indirectly own equity interests in Tallgrass Energy Holdings, 
Tallgrass Equity and TEGP through Tallgrass KC, an entity controlled by Mr. Dehaemers. As of February 15, 2017, our Named 
Executive Officers directly owned, in the aggregate, 572,652 of TEGP's Class A shares (excluding any unvested LTIP Awards).
As of February 15, 2017, Tallgrass KC owned 27,376,110 Class B Shares in TEGP and 27,376,110 Units in Tallgrass Equity,
representing an approximate 17.4% ownership interest in TEGP and Tallgrass Equity, respectively. On such date, Tallgrass KC 
also owned approximately 27.61% of the outstanding equity interests in Tallgrass Energy Holdings. 

Recovery of Prior Awards. Except as provided by applicable laws and regulations, we do not have a policy with respect to 

adjustment or recovery of awards or payments if relevant company performance measures upon which previous awards were 
based are restated or otherwise adjusted in a manner that would have reduced the size of such award or payment if previously 
known.

Section 162(m). With respect to the deduction limitations under Section 162(m) of the Code, we are a limited partnership 

and do not fall within the definition of a "corporation" under Section 162(m).

142

Change-in-Control Triggers and Termination Payments. The equity participation unit and equity participation share grants 

to our Named Executive Officers include accelerated vesting triggered upon a change of control, as defined in the respective 
award agreements. The provision of equity acceleration for defined changes of control help to create a retention tool by 
assuring the executive that the benefit of the compensation arrangement will be at least partially realized despite the occurrence 
of an event that could materially alter the executive's employment arrangement. In addition, the employment agreement for Mr.
Dehaemers provides for severance in the event his employment is terminated without "cause" or in the event he resigns for 
"good reason." See "Potential Payments upon Termination or Change-in-Control." No other Named Executive Officer has a 
contractual right to receive severance in the event of a termination of employment.

Relation of Compensation Policies and Practices to Risk Management

Our compensation policies and practices are designed to provide rewards for short-term and long-term performance, both 

on an individual basis and at the entity level. In general, optimal financial and operational performance, particularly in a 
competitive business like ours, requires some degree of risk-taking. Accordingly, the use of compensation as an incentive for 
performance could potentially cause management and others to take unnecessary or excessive risks to reach the performance 
thresholds. For us, such risks would primarily attach to the execution and financing of capital expansion projects and asset 
acquisitions and the realization of associated returns from both, as well as to certain commercial activities conducted in our 
operational segments.

From a risk management perspective, we monitor and structure our commercial activities in a manner intended to control 

and minimize the potential for unwarranted risk-taking. See Note 10 – Risk Management to our Consolidated Financial 
Statements in Item 8.—Financial Statements and Supplementary Data. We also monitor and measure our capital projects and 
acquisitions relative to expectations. In general, we believe our compensation arrangements serve to minimize the incentive for 
unwarranted risk-taking to achieve short-term, unsustainable results. See "Compensation Discussion and Analysis – Relation of 
Compensation Elements to Compensation Objectives."

In combination with our risk-management practices, we do not believe that risks arising from our compensation policies 

and practices for our employees are reasonably likely to have a material adverse effect on us.

(1) Reflects actual salary received. Salary adjustments are typically implemented during February, which results in odd 

amounts actually received by the indicated Named Executive Officer. In our annual report on Form 10-K/A for the year 
ended December 31, 2014, the Named Executive Officer's adjusted annual salary, rather than the actual amount of salary 
received, was reported in the salary column for 2014.

(2) Represents discretionary bonuses paid in 2017, 2016 and 2015 based on performance in 2016, 2015 and 2014, respectively,
as well as a bonus of $1,000 after tax that was paid to all employees in 2016 and a $1,000 pre-tax bonus that was paid to all 
employees in 2015 and 2014.

(3) The amounts in this column include both equity participation units granted pursuant to the TEP LTIP and equity 

participation shares granted pursuant to the TEGP LTIP. Mr. Jones and Mr. Watkins were the only Named Executive 
Officers to receive grants under the TEP LTIP during 2016 and Mr. Watkins was the only Named Executive Officer to 
receive grants under the TEGP LTIP during 2015. In addition, the amounts in this column represent the aggregate grant 
date fair value determined in accordance with ASC Topic 718 for equity participation units, or EPUs, granted under the 
TEP LTIP and equity participation shares granted under the TEGP LTIP. Pursuant to SEC rules, the amounts shown in the 
Summary Compensation Table for awards subject to performance conditions are based on the probable outcome as of the 
date of grant and exclude the impact of estimated forfeitures. The Equity participation units and equity participation shares 
are non-participating, therefore the grant date fair value is discounted from the grant date fair value of TEP's common units 
or TEGP's Class A shares, as appropriate, for the present value of the expected (but non-participating) future dividends 
during the vesting period. For additional information, see Note 16 – Equity-Based Compensation to our Consolidated 
Financial Statements in Item 8.—Financial Statements and Supplementary Data. These amounts do not correspond to the 
actual value that will be recognized by the executive.

Mr. Dehaemers, $26,500 for Mr. Moler, $26,500 for Mr. Brauchle, $23,629 for Mr. Jones, and $22,297 for Mr. Watkins for 
the year ended December 31, 2016, $26,500 for Mr. Dehaemers, $26,500 for Mr. Moler, $26,477 for Mr. Brauchle, and 
$21,232 for Mr. Watkins for the year ended December 31, 2015, and $30,000 for Mr. Dehaemers, $29,615 for Mr. Moler,
and $25,519 for Mr. Brauchle for the year ended December 31, 2014) and the dollar value of premiums paid for group life, 
accidental death and dismemberment insurance.

(5) Mr. Jones was appointed Vice President, General Counsel and Secretary of TEP and TEGP effective July 1, 2016.

Employment Agreement

On November 2, 2016, Mr. Dehaemers entered into a second amended and restated employment agreement with Tallgrass
Management, our general partner, Tallgrass Energy Holdings, Tallgrass Equity and TEGP Management, pursuant to which he 
agreed to serve as the President and Chief Executive Officer of our general partner. Under the terms of the employment 
agreement, Mr. Dehaemers is entitled to receive an annual salary of $300,000. In addition, Mr. Dehaemers is entitled to receive 
(i) benefits that are normally provided to senior executives of Tallgrass Management, (ii) reimbursement for all ordinary and 
necessary out-of-pocket expenses incurred by Mr. Dehaemers, and (iii) a policy of director and officer liability insurance. Mr.
Dehaemers' employment is "at-will" and may be terminated at any time.

For a discussion of certain payments that Mr. Dehaemers may be entitled to upon the termination of his employment, 

please read "Potential Payments Upon Termination or a Change-in-Control."

Potential Payments upon Termination or Change-in-Control

Termination

The employment agreement for Mr. Dehaemers provides that in the event his employment is terminated without "cause" or 

in the event he resigns for "good reason" he will receive: (i) a severance payment equal to $900,000, payable in a lump sum 
within 60 days after the termination of his employment; and (ii) directors and officers liability insurance coverage for so long as 
he is subject to any claim arising from his employment by TEP and its Affiliates. In addition, upon any such termination, Mr.
Dehaemers would receive payments related to his accrued and unpaid expenses, salary and benefits. Under Mr. Dehaemers' 
employment agreement:

•

•

"Cause" means (i) his conviction of, or plea of nolo contendere to, any crime or offense constituting a felony under 
applicable law; (ii) his commission of fraud or embezzlement against Tallgrass Management or certain of its affiliates;
(iii) gross neglect by Mr. Dehaemers of, or gross or willful misconduct of Mr. Dehaemers in connection with the 
performance of, his duties that is not cured within 30 days of receiving a written notice of such gross neglect or gross 
or willful misconduct; (iv) Mr. Dehaemers' willful failure or refusal to carry out the reasonable and lawful instructions 
of the board of managers of the entity with ultimate control over our general partner; (v) Mr. Dehaemers' failure to 
perform the duties and responsibilities of his office as his primary business activity; (vi) a judicial determination that 
Mr. Dehaemers has breached his fiduciary duties with respect to Tallgrass Management or certain of its affiliates; or 
(vii) Mr. Dehaemers' willful and material breach of his obligations under the operating agreements of our general 
partner or certain affiliates of Tallgrass Management, in his capacity as an officer of such entities.

"Good reason" means (i) a material diminution of Mr. Dehaemers' duties and responsibilities to Tallgrass Management 
or certain of its affiliates to a level inconsistent with those of a chief executive officer; (ii) a material reduction in Mr.
Dehaemers' cash compensation or the aggregate welfare benefits provided to him (excluding any reduction that is not 
limited to him specifically); (iii) a willful or intentional breach of his employment agreement by Tallgrass
Management; or (iv) a willful or intentional breach by our general partner or certain affiliates of Tallgrass
Management of a material provision of the applicable operating agreements of such entities that has a material and 
adverse effect on Mr. Dehaemers.

Other than the payments to Mr. Dehaemers pursuant to his employment agreement as described above, we are not 

obligated to make any cash payment or provide any benefit to our Named Executive Officers if their employment is terminated 
by us or by the Named Executive Officer, other than the payment of accrued and unpaid expenses, salary and benefits. In 
addition, any LTIP Awards that have not vested and/or become exercisable are terminated upon the termination of such Named 
Executive Officer's employment.

Change in Control

Employment Agreement. Upon a change in control, the employment agreement of Mr. Dehaemers generally does not 

provide for termination or severance benefits or payments in addition to those described above.

LTIP Award Agreements. In addition to the foregoing payments to Mr. Dehaemers pursuant to his employment agreement, 

the TEP LTIP Awards and TEGP LTIP Awards held by our Named Executive Officers typically provide for acceleration of

become exercisable in full upon a "change in control" of us or our general partner and the TEGP LTIP Awards held by our 
Named Executive Officers vest and/or become exercisable in full upon a "change in control" of TEGP or TEGP's general 
partner.

•

•

•

any Person or group, other than Tallgrass Equity or its affiliates, becomes the owner, by way of merger, consolidation, 
recapitalization, reorganization or otherwise, of 50% or more of (A) the combined voting power of the equity interests

Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters

The following table sets forth the beneficial ownership of our units as of February 8, 2017 owned by:

•

•

•

•

each person known by us to be a beneficial owner of more than 5% of the units;

each of the directors of our general partner;

each of the named executive officers of our general partner; and

all directors and executive officers of our general partner as a group.

 The amounts and percentage of units beneficially owned are reported on the basis of regulations of the SEC governing the 
determination of beneficial ownership of securities. Under the rules of the SEC, a person is deemed to be a "beneficial owner" 
of a security if that person has or shares "voting power," which includes the power to vote or to direct the voting of such 

149

security, or "investment power," which includes the power to dispose of or to direct the disposition of such security. Except as 
indicated by footnote, the persons named in the table below have sole voting and investment power with respect to all units 
shown as beneficially owned by them, subject to community property laws where applicable.

Percentage of total units to be beneficially owned is based on 72,139,038 common units outstanding as of February 8, 

2017.

For additional information regarding the TEP LTIP, see Note 16 – Equity-Based Compensation to our Consolidated 

Financial Statements in Item 8.—Financial Statements and Supplementary Data of this Annual Report.

Item 13. Certain Relationships and Related Transactions, and Director Independence 

As of February 15, 2017, Tallgrass Development owned 5,619,218 common units representing approximately 7.79% of our 

outstanding limited partner common units and Tallgrass Equity owned 20,000,000 common units representing approximately 
27.72% of our outstanding limited partner common units. In addition, our general partner owns 834,391 general partner units 
representing an approximate 1.14% general partner interest in us and all of the incentive distribution rights.

Distributions and Payments to Our General Partner and Its Affiliates

The following information summarizes the distributions and payments made or to be made by us to our general partner and 

its affiliates in connection with our formation, ongoing operation and any liquidation of us. These distributions and payments 
were determined by and among affiliated entities and, consequently, are not the result of arm's-length negotiations.

Distributions of available cash to our general partner and its affiliates. We will generally make distributions of available 

cash to common unitholders pro rata (including Tallgrass Development as the holder of an aggregate of 5,619,218 common 
units) and to our general partner as follows: (1) an approximate 1.14% general partner interest with respect to TEP GP's general 
partner units and (2) as distributions of available cash exceed the MQD and other higher target levels specified in our 
partnership agreement, increasing percentages of distributions with respect to its IDRs, up to 48% of the distributions above the 
highest target level. Assuming we have sufficient available cash to pay the full MQD on all of our outstanding units for four 
quarters, our general partner and its affiliates would receive an annual distribution of approximately $1.0 million on their 
general partner units and approximately $30.0 million on their common units based on their ownership as of February 15, 2017.
We have distributed available cash in excess of the MQD since the quarterly period ending September 30, 2013.

Payments to our general partner and its affiliates. Neither our general partner nor Tallgrass Energy Holdings and its 
affiliates receive a management fee or other compensation for managing us. Our general partner and Tallgrass Energy Holdings 
and its affiliates are reimbursed, however, for all direct and indirect expenses incurred on our behalf pursuant to our partnership 
agreement and the TEP Omnibus Agreement. Neither our partnership agreement nor the TEP Omnibus Agreement limit the 
amount of expenses for which our general partner or Tallgrass Energy Holdings and its affiliates may be reimbursed. Our 
partnership agreement provides that our general partner will determine in good faith the expenses that are allocable to us.

Withdrawal or removal of our general partner. If our general partner withdraws or is removed, its general partner interest 
and its IDRs will either be sold to the new general partner for cash or converted into common units, in each case for an amount 
equal to the fair market value of those interests.

Liquidation Stage. Upon our liquidation, the partners, including our general partner, will be entitled to receive liquidating 

distributions according to their particular capital account balances, as further detailed in our limited partnership agreement.

151

 
TEP Omnibus Agreement

Upon the closing of the IPO, we entered into the TEP Omnibus Agreement with Tallgrass Development, its general partner,

Tallgrass Energy Holdings, and our general partner that governs our relationship with them regarding the following matters:

•

•

•

•

•

the provision by Tallgrass Energy Holdings to us of certain administrative services and our agreement to reimburse it 
for such services;

the provision by Tallgrass Energy Holdings of such employees as may be necessary to operate and manage our 
business, and our agreement to reimburse it for the expenses associated with such employees;

certain indemnification obligations;

our use of the name "Tallgrass" and related marks; and

our right of first offer to acquire certain assets, including each of the Retained Assets from Tallgrass Development, if 
Tallgrass Development decides to sell such assets.

Reimbursement of General and Administrative Expenses

Pursuant to the TEP Omnibus Agreement, Tallgrass Energy Holdings performs, or causes its affiliates to perform, 

centralized corporate, general and administrative services for us, such as legal, corporate record keeping, planning, budgeting, 
regulatory, accounting, billing, business development, treasury, insurance administration and claims processing, risk 
management, health, safety and environmental, information technology, human resources, investor relations, cash management 
and banking, payroll, internal audit, taxes and engineering. In exchange, we reimburse it for expenses incurred in providing 
these services. The reimbursements to our general partner and Tallgrass Energy Holdings and its affiliates are made prior to 
cash distributions to our common unitholders. The TEP Omnibus Agreement further provides that we will reimburse Tallgrass
Energy Holdings and its affiliates for our allocable portion of the premiums on any insurance policies covering our assets. We
anticipate reimbursement to Tallgrass Energy Holdings and its affiliates will vary with the size and scale of our operations, 
among other factors.

For the years ended December 31, 2016, 2015 and 2014, we reimbursed Tallgrass Energy Holdings $39.9 million, $37.5

million and $23.5 million, respectively, pursuant to the TEP Omnibus Agreement.

Indemnification

Under the terms of the TEP Omnibus Agreement, Tallgrass Development is required to indemnify us from liabilities 

arising out of any federal, state and local income tax liabilities attributable to the ownership and operation of the assets 
contributed to us in connection with the IPO until 60 days after the applicable statute of limitations. Tallgrass Development also 
agreed to use commercially reasonable efforts to obtain indemnification from Kinder Morgan for losses suffered or incurred by 
us with respect to the assets contributed to us as part of the IPO, to the extent that Kinder Morgan is obligated to indemnify 
Tallgrass Development under the purchase and sale agreement pursuant to which Tallgrass Development acquired the 
contributed assets and remit any proceeds received from Kinder Morgan pursuant to such indemnification obligations to us.

Kinder Morgan's indemnity obligations under the Kinder Morgan purchase agreement generally survived through 

February 13, 2014, although certain specified indemnities last for longer periods of time. Under the TEP Omnibus Agreement,
we have agreed to indemnify Tallgrass Development for events and conditions associated with the operation of the contributed 
assets that occur on or after the closing of the IPO.

Right of First Offer

Under the terms of the TEP Omnibus Agreement, Tallgrass Development has granted us a right of first offer, for so long as 
Tallgrass Development or its affiliates, individually or as part of a group, control our general partner, on (i) the Retained Assets
and (ii) any assets that are hereafter developed, constructed or acquired by Tallgrass Development or its subsidiaries (excluding 
the Partnership and its subsidiaries) for the purpose of processing natural gas in Natrona, Converse or Campbell counties in 
Wyoming, which we refer to collectively as the ROFO Assets. If Tallgrass Development or any of its affiliates decide to 
attempt to sell (other than to an affiliate of Tallgrass Development, excluding TEP and its subsidiaries) a ROFO Asset, Tallgrass
Development or its affiliate will notify us in advance and, prior to selling such ROFO Asset to a third party, will negotiate with 
us exclusively and in good faith for a period of 45 days in order to give us an opportunity to enter into definitive documentation 
for the purchase and sale of such ROFO Asset on terms that are mutually acceptable to Tallgrass Development or its affiliate
and us. If we and Tallgrass Development or its affiliate have not entered into a letter of intent or a definitive purchase and sale 
agreement with respect to such ROFO Asset within such 45-day period, Tallgrass Development or its affiliate will have the 
right to sell such ROFO Asset to a third party following the expiration of such 45-day period on any terms that are acceptable to 
Tallgrass Development or its affiliate and such third party. Our decision to acquire or not to acquire a ROFO Asset pursuant to 
this right will require the approval of the conflicts committee of the board of directors of our general partner.

152

Amendment and Termination

The TEP Omnibus Agreement can be amended by written agreement of all parties to the agreement. However, we may not 

agree to any amendment or modification that would, in the determination of our general partner, be adverse in any material 
respect to the holders of our common units without the prior approval of the conflicts committee. In the event of (i) a "change 
in control" (as defined in the TEP Omnibus Agreement) of the partnership or (ii) the removal of Tallgrass MLP GP, LLC as our 
general partner in circumstances where "cause" (as defined in our partnership agreement) does not exist and the common units 
held by our general partner and its affiliates were not voted in favor of such removal, the TEP Omnibus Agreement (other than 
the indemnification and reimbursement provisions therein) will be terminable by Tallgrass Development, and we will have a 
90-day transition period to cease our use of the name "Tallgrass" and related marks.

Acquisitions from Tallgrass Development

On April 1, 2014, Tallgrass MLP Operations, LLC, a Delaware limited liability company and our wholly-owned subsidiary 

acquired 100% of the issued and outstanding membership interests in Trailblazer from Tallgrass Operations, LLC, a Delaware 
limited liability company and wholly-owned direct subsidiary of Tallgrass Development ("Tallgrass Operations"), for total 
consideration valued at approximately $164 million, pursuant to that certain Contribution and Sale Agreement by and between 
Tallgrass Development, Tallgrass Operations, and us.

Effective September 1, 2014, we acquired a 33.3% membership interest in Pony Express, from Tallgrass Development for 

total consideration of approximately $600 million pursuant to that certain Contribution and Transfer Agreement by and between 
Tallgrass Development, Pony Express, Tallgrass Operations, and us. At closing, we entered into a Second Amended and 
Restated Limited Liability Company Agreement of Pony Express effective September 1, 2014 with Tallgrass Development and 
Pony Express, which provided us a minimum quarterly preference payment of $16.65 million through the quarter ending 
September 30, 2015 with distributions thereafter shared in accordance with the terms of the Second Amended and Restated 
Limited Liability Company Agreement. In connection with the transaction, Pony Express entered into a Cash Management 
Agreement effective August 27, 2014, under which cash balances were swept daily and recorded as loans from Pony Express to 
Tallgrass Development. $270 million of the total consideration was subsequently swept to Tallgrass Development and was 
recorded as a related party loan which accrued interest at Tallgrass Development's incremental borrowing rate. As of September 
1, 2014, balances lent to Tallgrass Development under the cash management agreement were classified as related party 
receivables on our consolidated balance sheet and were cash settled.

Effective March 1, 2015, we acquired an additional 33.3% membership interest in Pony Express from Tallgrass

Development for total consideration of approximately $700 million pursuant to that certain Purchase and Sale Agreement by 
and between Tallgrass Development, Tallgrass Operations and us. At closing, TEP, Tallgrass Development and Pony Express 
entered into a Third Amended and Restated Limited Liability Company Agreement of Pony Express effective March 1, 2015, 
which provided us a minimum quarterly preference payment of $36.65 million through the quarter ending December 31, 2015 
with distributions thereafter shared in accordance with the terms of the Third Amended and Restated Limited Liability 
Company Agreement.

Effective January 1, 2016, we acquired an additional 31.3% membership interest in Pony Express from Tallgrass
Development for total cash consideration of approximately $475 million and the issuance of 6,518,000 TEP common units, 
which TEP common units are subject to a call option granted by Tallgrass Operations in favor of us, pursuant to that certain 
Contribution and Transfer Agreement by and between Tallgrass Development, Tallgrass Operations and us. In July 2016, 
October 2016 and on February 1, 2017, we exercised the call option granted by Tallgrass Development covering 3,563,146,
1,251,760 and 1,703,094 common units, respectively. These common units were deemed canceled upon the exercise of the call 
option and as of such exercise date were no longer issued and outstanding. As of February 15, 2017, no common units 
remained subject to the call option.

On May 6, 2016, Tallgrass Development assigned us its right to purchase a 25% membership interest in Rockies Express 

from a unit of Sempra U.S. Gas and Power ("Sempra") pursuant to the purchase agreement originally entered into between 
Tallgrass Development's wholly-owned subsidiary and Sempra in March 2016. Subsequently on May 6, 2016, we closed the 
purchase of a 25% membership interest in Rockies Express from Sempra pursuant to the purchase agreement for cash 
consideration of approximately $436.0 million, after making the adjustments to the purchase price required by the purchase 
agreement.

Effective January 1, 2017, we acquired 100% of the issued and outstanding membership interests in Terminals and 100%
of the issued and outstanding membership interests in NatGas from TD for total cash consideration of $140 million, pursuant to 
that certain Purchase and Sale Agreement by and between Tallgrass Development, Tallgrass Operations and us. 

153

Following an offer received from Tallgrass Development with respect to common units owned by Tallgrass Development 

not subject to the call option, we repurchased 736,262 common units from Tallgrass Development at an aggregate price of 
approximately $35.3 million, or $47.99 per common unit, on February 1, 2017, which was approved by the conflicts committee 
of the board of directors of our general partner.

Competition

Under our partnership agreement, Tallgrass Development and its affiliates are expressly permitted to compete with us. 
Tallgrass Development and any of its affiliates, including EMG and Kelso may acquire, construct or dispose of additional 
transportation, storage, terminalling and processing or other assets in the future without any obligation to offer us the 
opportunity to purchase or construct those assets.

Contracts with Affiliates

Pony Express is party to a terminal lease and operating agreement with Tallgrass Sterling Terminal, LLC ("Sterling 

Terminal"), which was an indirect wholly-owned subsidiary of Tallgrass Development prior to our acquisition in January 2017. 
Pursuant to such agreement, Pony Express leases approximately 1.3 million barrels of crude oil storage and Sterling Terminal
provides associated crude oil terminalling services. Pony Express pays Sterling Terminal a fixed monthly charge of $942,000 
per month, plus a volumetric charge of $0.07 per barrel for each barrel delivered to the terminal in excess of 9,424,000 per 
month, subject in both cases to an annual 2% escalator. The initial five-year term of the agreement expires in May 2020. Pony 
Express made lease payments to Sterling Terminal of $11.5 million and $7.6 million during the years ended December 31, 2016 
and 2015, respectively, pursuant to the agreement.

In May 2016, Pony Express entered into an electric service master meter agreement with Terminals, which was an indirect 

wholly-owned subsidiary of Tallgrass Development prior to our acquisition in January 2017. Pursuant to such agreement, 
Terminals receives electric power from Pony Express at the Sterling Terminal. Terminals pays Pony Express for its usage based 
on the charges incurred by Pony Express from its third-party electric service provider. Terminals made payments to Pony 
Express under the agreement of $0.4 million during the year ended December 31, 2016.

Other Transactions

Tallgrass Management, LLC, an affiliate of our general partner, has one employee who is an immediate family member of 
a former executive officer of our general partner. Zach Rider, a manager of corporate development, is the son of George Rider,
the former Executive Vice President, General Counsel and Secretary of TEP GP. For the years ended December 31, 2016, 2015 
and 2014, he received cash compensation of $186,246, $179,357 and $159,846, respectively, and standard employee benefits of 
approximately $11,725, $9,977 and $13,747, respectively. For the year ended December 31, 2015, he was awarded 3,800 
unvested EPUs with a grant date value of $38.62 per EPU on terms consistent with all eligible employees. As of July 1, 2016, 
George Rider has retired and is no longer employed by Tallgrass Management, LLC.

Procedures for Review, Approval or Ratification of Transactions with Related Persons

The board of directors of our general partner has adopted a related party transactions policy (the "Policy"), which 

supplements the conflict of interest provisions in our code of business conduct and ethics. According to the Policy, a "Related 
Party Transaction" is an actual or proposed transaction, arrangement or relationship (or any series of similar transactions, 
arrangements or relationships) in which (a) the Partnership, our general partner or any of the Partnership's subsidiaries 
(collectively, the "Partnership Group") was, is or will be a participant, (b) the amount involved exceeds $120,000, and (c) in 
which any Related Party had, has or will have a direct or indirect material interest. The Policy's definition of a "Related Party" 
is in line with the definition set forth in the instructions to Item 404(a) of Regulation S-K promulgated by the SEC. 
Transactions resolved under the conflicts provisions of our partnership agreement are not required to be reviewed or approved 
under the policy.

Under the Policy, the General Counsel and Chief Financial Officer or Chief Accounting Officer are responsible for 
determining whether a Related Party Transaction requires the approval of the Audit Committee. The Audit Committee is 
responsible for evaluating and assessing a proposed transaction based on the relevant facts and circumstances, including 
comparing the terms of the proposed transaction to the terms available to unrelated third parties. The Audit Committee shall 
approve only those Related Party Transactions that are either (i) on terms no less favorable to the Partnership Group than those 
generally being provided to or available from unrelated third parties or (ii) are fair and reasonable to the Partnership Group, 
taking into account the totality of the relationships between the parties involved. 

154

If the General Counsel determines it is impractical or undesirable to wait until an Audit Committee meeting to consummate 

a Related Party Transaction, the chairman of the Audit Committee may review and approve the Related Party Transaction in 
accordance with the procedures set forth in the Policy. However, any such approval (and its rationale) must be reported to the 
Audit Committee at the next regularly scheduled meeting. A Related Party Transaction entered into without pre-approval of the 
Audit Committee shall not be deemed to violate the Policy, or be invalid or unenforceable, so long as the transaction is brought 
to the Audit Committee as promptly as reasonably practical after it is entered into and is subsequently ratified by the Audit
Committee. If the Audit Committee determines not to ratify a Related Party Transaction that has been commenced without 
approval, the Audit Committee may direct the immediate discontinuation or rescission of the transaction, or modify the 
transaction to make it acceptable for ratification.

Report of Independent Registered Public Accounting Firm

To the Board of Directors of Rockies Express Pipeline LLC:

We have audited the accompanying financial statements of Rockies Express Pipeline LLC, which comprise the balance sheets
as of December 31, 2016 and 2015, and the related statements of income, members’ equity, and cash flows for each of the three 
years in the period ended December 31, 2016.

Management's Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of the financial statements in accordance with accounting 
principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of 
internal control relevant to the preparation and fair presentation of financial statements that are free from material 
misstatement, whether due to fraud or error.

Auditors’ Responsibility

Our responsibility is to express an opinion on the financial statements based on our audits. We conducted our audits in 
accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan 
and perform the audit to obtain reasonable assurance about whether the financial statements are free from material 
misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial 
statements. The procedures selected depend on our judgment, including the assessment of the risks of material misstatement of 
the financial statements, whether due to fraud or error.  In making those risk assessments, we consider internal control relevant 
to the Company's preparation and fair presentation of the financial statements in order to design audit procedures that are 
appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's 
internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting 
policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall 
presentation of the financial statements. We believe that the audit evidence we have obtained is sufficient and appropriate to 
provide a basis for our audit opinion.

Opinion

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of 
Rockies Express Pipeline LLC as of December 31, 2016 and 2015, and the results of its operations and its cash flows for each 
of the three years in the period ended December 31, 2016, in accordance with accounting principles generally accepted in the 
United States of America.

Emphasis of Matter

As described in Note 6 to the financial statements, the Company has significant transactions with related parties.  Our opinion 
is not modified with respect to this matter.

ROCKIES EXPRESS PIPELINE LLC
NOTES TO FINANCIAL STATEMENTS

1. Description of Business

Rockies Express Pipeline LLC ("Rockies Express") is a Federal Energy Regulatory Commission ("FERC") regulated 

natural gas transportation system with approximately 1,712 miles of natural gas pipeline, including laterals, extending from 
Opal, Wyoming and Meeker, Colorado to Clarington, Ohio and consisting of three zones:

•

•

•

Zone 1 - a 328-mile pipeline from the Meeker Hub in Northwest Colorado, across Southern Wyoming to the Cheyenne 
Hub in Weld County, Colorado capable of transporting 2.0 Bcf/d of natural gas from west to east;

Zone 2 - a 714-mile pipeline from the Cheyenne Hub to an interconnect in Audrain County, Missouri capable of 
transporting 1.8 Bcf/d of natural gas from west to east; and

Zone 3 - a 643-mile pipeline from Audrain County, Missouri to Clarington, Ohio, which is bi-directional and capable 
of transporting 1.8 Bcf/d of natural gas from west to east and 2.6 Bcf/d of natural gas from east to west.

The member interests and voting rights in Rockies Express as of December 31, 2016 are as follows:

•

•

•

50% - Rockies Express Holdings, LLC ("REX Holdings"), an indirect wholly owned subsidiary of Tallgrass
Development, LP ("TD");

25% - TEP REX Holdings, LLC ("TEP REX"), an indirect wholly owned subsidiary of Tallgrass Energy Partners, LP
("TEP"); and 

25% - P66REX LLC, formerly known as COPREX LLC, a wholly owned subsidiary of Phillips 66.

On March 29, 2016, REX Holdings signed a Purchase Agreement with Sempra REX Holdings, LLC ("Sempra") to acquire 
Sempra's 25% membership interest in Rockies Express for cash consideration of $440 million, subject to adjustment under the 
Purchase Agreement. A subsidiary of Phillips 66, which owns a 25% membership interest in Rockies Express, waived its right 
to purchase its proportionate share of Sempra's 25% membership interest. In exchange, TD and Sempra agreed to amend the 
Rockies Express limited liability company agreement to (i) increase the percentage with respect to matters that require 
approval, consent, or presence of the members of Rockies Express from 75% to 80%, and (ii) with respect to certain 
fundamental decisions, increase the required vote from 85% to 90% of the membership interests (the "REX Amendment").

On May 6, 2016, TEP REX and REX Holdings entered into an Assignment and Assumption Agreement pursuant to which 
REX Holdings assigned to TEP REX all of its rights under the Purchase Agreement and, in exchange, TEP REX assumed all of 
the rights and obligations of REX Holdings under the Purchase Agreement. Subsequently on May 6, 2016, TEP REX closed the 
purchase of a 25% membership interest in Rockies Express from Sempra pursuant to the Purchase Agreement for cash 
consideration of approximately $436.0 million, after making the adjustments to the purchase price required by the Purchase 
Agreement. The REX Amendment became effective immediately prior to closing of the sale of the 25% membership interest.

2. Summary of Significant Accounting Policies

Basis of Presentation

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of 

America ("GAAP") requires management to make estimates and assumptions. These estimates and assumptions affect the 
reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of 
revenues and expenses. Actual results could differ from these estimates. Certain prior year amounts have been reclassified to 
conform to the current presentation.

Cash and Cash Equivalents

Rockies Express considers all highly liquid investments purchased with an original maturity of three months or less to be 

cash equivalents. 

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are carried at their estimated collectible amounts. Rockies Express makes periodic reviews and 
evaluations of the appropriateness of the allowance for doubtful accounts based on a statistical analysis of historical defaults, 
and adjustments are recorded as necessary for changes in circumstances and customer-specific information. When specific 
receivables are determined to be uncollectible, the reserve and receivable are relieved. Our allowance for doubtful accounts 
totaled $2.0 million and $1.0 million at December 31, 2016 and 2015, respectively.

163

Fuel Recovery Mechanism

Rockies Express obtains natural gas quantities from its shippers as reimbursement for fuel consumed at compressor 

stations and other locations on its system as well as for natural gas quantities lost and otherwise unaccounted for, in accordance 
with its tariff and applicable contract terms. Rockies Express tracks the volume and value of associated over- or under-
collections of fuel and lost and unaccounted for quantities through a tracking mechanism referred to as "fuel tracker." Those
amounts are recorded as an addition or reduction to a regulatory asset or liability balance representing the amounts to be 
recovered from or refunded to customers through the fuel tracker mechanisms. Fuel tracker volumes are valued using a 
weighted-average monthly index price.

Accounting for Regulatory Activities

Rockies Express' regulated activities are accounted for in accordance with the "Regulated Operations" Topic of the 

Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("Codification"). This Topic prescribes the 
circumstances in which the application of GAAP is affected by the economic effects of regulation. Regulatory assets and 
liabilities represent probable future revenues or expenses to Rockies Express associated with certain charges and credits that 
will be recovered from or refunded to customers through the ratemaking process. Rockies Express recorded regulatory assets of 
approximately $12.3 million and $0.3 million at December 31, 2016 and 2015, respectively, and regulatory liabilities of 
approximately $10,000 and $0.5 million at December 31, 2016 and 2015, respectively. Regulatory assets and liabilities at 
December 31, 2016 and 2015 were primarily attributable to the fuel tracker discussed in "Fuel Recovery Mechanism" above.
For additional details see Note 9 – Regulatory Matters.

Gas Imbalances

Gas imbalances receivable and payable reflect gas volumes owed between Rockies Express and its customers. Gas 

imbalances represent the difference between customer nominated versus actual gas receipts from and gas deliveries to 
interconnecting pipelines under various operational balancing agreements. Gas imbalances are settled in cash or made up in-
kind subject to the terms of the various agreements and are valued at the average monthly index price.

Property, Plant and Equipment

Property, plant and equipment is stated at historical cost, which for constructed assets includes indirect costs such as 

payroll taxes, other employee benefits, allowance for funds used during construction and other costs directly related to the 
projects. Expenditures that increase capacities, improve efficiencies or extend useful lives are capitalized and depreciated over 
the remaining useful life of the asset or major asset component. We also capitalize certain costs directly related to the 
construction of assets, including internal labor costs, interest and engineering costs.

Routine maintenance, repairs and renewal costs are expensed as incurred. The cost of normal retirements of depreciable 
utility property, plant and equipment, plus the cost of removal less salvage value and any gain or loss recognized, is recorded in 
accumulated depreciation with no effect on current period earnings. Gains or losses are recognized upon retirement of property,
plant and equipment constituting an operating unit or system, and land, when sold or abandoned and costs of removal or 
salvage are expensed when incurred.

Rockies Express maintains natural gas in its pipeline, known as "line pack," which serves to maintain the necessary 
pressure to allow efficient transmission of natural gas. Line pack is capitalized within "Property, plant and equipment, net" on 
the balance sheets and depreciated over the estimated useful life of the pipeline. 

Impairment of Long-Lived Assets

Rockies Express reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that 
the carrying amount of an asset may not be recoverable. An impairment loss results when the estimated undiscounted future net 
cash flows expected to result from the asset's use and its eventual disposition are less than its carrying amount. Rockies Express 
assesses its long-lived assets for impairment in accordance with the relevant Codification guidance. A long-lived asset is tested 
for impairment whenever events or changes in circumstances indicate its carrying amount may exceed its fair value.

Examples of long-lived asset impairment indicators include:

•

•

•

a significant decrease in the market value of a long-lived asset or group;

a significant adverse change in the extent or manner in which a long-lived asset or asset group is being used or in its 
physical condition;

a significant adverse change in legal factors or in the business climate could affect the value of a long-lived asset or 
asset group, including an adverse action or assessment by a regulator which would exclude allowable costs from the 
rate-making process;

164

•

•

•

an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction 
of the long-lived asset or asset group;

a current period operating cash flow loss combined with a history of operating cash flow losses or a projection or 
forecast that demonstrates continuing losses associated with the use of a long-lived asset or asset group; and

a current expectation that, more likely than not, a long-lived asset or asset group will be sold or otherwise disposed of 
significantly before the end of its previously estimated useful life. 

When an impairment indicator is present, Rockies Express first assesses the recoverability of the long-lived assets by 
comparing the sum of the undiscounted future cash flows expected to result from the use and eventual disposition of the asset 
to the carrying amount of the asset. If the carrying amount is higher than the undiscounted future cash flows, the fair value of 
the asset is assessed using a discounted cash flow analysis to determine the amount of impairment, if any, to be recognized.

Depreciation and Amortization

Depreciation is computed based on the straight-line method over the estimated useful lives of property, plant and 
equipment. The annual composite rate of depreciation for the years ended December 31, 2016, 2015, and 2014 was 2.86%.

Allowance for Funds Used During Construction

Included in the cost of "Property, plant and equipment, net" on the accompanying balance sheets is an allowance for funds 

used during construction ("AFUDC"). AFUDC represents the estimated cost of debt, from borrowed funds, or the estimated 
cost of capital, from equity funds, during the construction period. During the years ended December 31, 2016, 2015, and 2014,
Rockies Express recognized AFUDC associated with the estimated cost of capital from equity funds of approximately $24.8
million, $6.5 million, and $3.3 million, respectively, recorded as "Other income, net" on the accompanying statements of 
income.

Revenue Recognition

Rockies Express provides various types of natural gas transportation services to its customers in which the natural gas 
remains the property of these customers at all times. In many cases (generally described as "firm service"), the customer pays a 
two-part rate that includes (i) a fixed-fee reserving the right to transport natural gas in Rockies Express' facilities and (ii) a per-
unit rate for volumes actually transported. The fixed-fee component of the overall rate is recognized as revenue in the period 
the service is provided. The per-unit charge is recognized as revenue when the volumes are delivered to the customers' agreed 
upon delivery point. In other cases (generally described as "interruptible service"), there is no fixed-fee associated with the 
services because the customer accepts the possibility that service may be interrupted at the discretion of Rockies Express in 
order to serve customers who have purchased firm service. In the case of interruptible service, revenue is recognized in the 
same manner utilized for the per-unit rate for volumes transported under firm service agreements. 

In addition to its "firm" and "interruptible" transportation services, Rockies Express also provides a natural gas park and 

loan service to assist customers in managing a short-term gas surplus or deficit and a pooling and wheeling service to assist 
customers in the aggregation of gas supply from physical point(s) within a specified hub to a central pooling point and the re-
delivery of gas supply to physical points within the same hub. Revenues are recognized as services are provided, in accordance 
with the terms negotiated under these contracts. 

Rockies Express recognizes revenue from natural gas sales when the natural gas is sold at a fixed or determinable price, 

delivery has occurred and title has transferred, and collectability of the revenue is reasonably assured. 

Debt Issuance Costs

Debt issuance costs are amortized to interest expense over the life of the debt using the straight-line-method, which 

approximates the effective interest rate method. Debt issuance costs associated with long-term debt are classified with the 
corresponding debt on the accompanying balance sheets. Debt issuance costs associated with revolving credit facilities or lines 
of credit are classified as deferred charges and other assets on the accompanying balance sheets.

Deferred Charges and Deferred Credits

Rockies Express has $4.5 million remaining of an initial $20.0 million deferred charge and deferred credit relating to a 
customer contract. The deferred charge is being amortized using a straight-line-method over the life of the related contract. 
Amortization of the deferred charge for each of the years ended December 31, 2016, 2015, and 2014 was $2.0 million and is 
included within transportation services revenues in the accompanying statements of income. The deferred credit is payable over 
a period of 10 years.

165

Environmental Matters

Rockies Express expenses or capitalizes, as appropriate, environmental expenditures that relate to current operations. 
Rockies Express expenses amounts that relate to an existing condition caused by past operations that do not contribute to 
current or future revenue generation. Rockies Express does not discount environmental liabilities to a net present value, and 
records environmental liabilities when environmental assessments and/or remedial efforts are probable and costs can be 
reasonably estimated. Generally, recording of these accruals coincides with the completion of a feasibility study or a 
commitment to a formal plan of action.

Fair Value

Fair value, as defined in the fair value measurement accounting guidance, is the price that would be received to sell an 
asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, or exit price. 
The fair value measurement accounting guidance requires that Rockies Express make assumptions that market participants 
would use in pricing an asset or liability based on the best information available. These factors include nonperformance risk 
(the risk that an obligation will not be fulfilled) and credit risk of the reporting entity (for liabilities) and of the counterparty 
(for assets). The fair value measurement guidance prohibits the inclusion of transaction costs and any adjustments for blockage 
factors in determining the instruments' fair value. The principal or most advantageous market should be considered from the 
perspective of the reporting entity. The fair value of current financial assets and liabilities approximate their reported carrying 
amounts as of December 31, 2016 and 2015.

Income Taxes

Rockies Express is a limited liability company that has elected to be treated as a partnership for income tax purposes. 
Accordingly, no provision for federal or state income taxes has been recorded in the financial statements of Rockies Express 
and the tax effects of Rockies Express' activities accrue to its Members.

New Accounting Pronouncements

Revenue Recognition

In May 2014, the FASB issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with 
Customers (Topic 606). ASU 2014-09 provides a comprehensive and converged set of principles-based revenue recognition 
guidelines which supersede the existing industry and transaction-specific standards. The core principle of the new guidance is 
that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that 
reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this core 
principle, entities must apply a five-step process to (1) identify the contract with a customer; (2) identify the performance 
obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations 
in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 also 
mandates disclosure of sufficient information to enable users of financial statements to understand the nature, amount, timing 
and uncertainty of revenue and cash flows arising from contracts with customers. The disclosure requirements include 
qualitative and quantitative information about contracts with customers, significant judgments and changes in judgments, and 
assets recognized from the costs to obtain or fulfill a contract.

Throughout 2015 and 2016, the FASB has issued a series of subsequent updates to the revenue recognition guidance in 
Topic 606, including ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, 
ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting 
Revenue Gross versus Net), ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance 
Obligations and Licensing, ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope 
Improvements and Practical Expedients, and ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, 
Revenue from Contracts with Customers.

The amendments in ASU 2014-09, ASU 2016-08, ASU 2016-10, ASU 2016-12, and ASU 2016-20 are effective for public 

entities for annual reporting periods beginning after December 15, 2017, and for interim periods within that reporting period. 
Early application is permitted for annual reporting periods beginning after December 15, 2016.

Rockies Express is currently evaluating the impact of our pending adoption of the revised guidance. The status of its 

implementation is as follows:

•

•

Rockies Express management has formed an implementation team that meets to discuss implementation challenges, 
technical interpretations, industry-specific treatment of certain revenue contract types, and project status.

Rockies Express management is currently reviewing contracts for each revenue stream identified. Through this 
process, management is determining and documenting expected changes in revenue recognition upon adoption of the 
revised guidance.

166

•

•

Rockies Express management plans to evaluate the potential information technology and internal control changes that 
will be required for adoption based on the findings from its contract review process.

Rockies Express management plans to provide internal training and awareness related to the revised guidance to the 
key stakeholders throughout its organization.

Rockies Express will continue to conduct its contract review process throughout 2017 and, as a result, areas of impact may 

be identified. Rockies Express is in the process of quantifying the impact of adoption but cannot reasonably estimate such 
amount at this time. Rockies Express expects to adopt the new standard on January 1, 2018 using the modified retrospective 
approach. This approach allows Rockies Express to apply the new standard to (i) all new contracts entered into after January 1, 
2018 and (ii) all existing contracts for which all (or substantially all) of the revenue has not been recognized under legacy 
revenue guidance as of January 1, 2018 through a cumulative adjustment to members' equity. Consolidated revenues presented 
in the comparative financial statements for periods prior to January 1, 2018 would not be revised.

ASU No. 2016-02, "Leases (Topic 842)"

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). ASU 2016-02 provides a comprehensive update 

to the lease accounting topic in the Codification intended to increase transparency and comparability among organizations by 
recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. 
The amendments in ASU 2016-02 include a revised definition of a lease as well as certain scope exceptions. The changes 
primarily impact lessee accounting, while lessor accounting is largely unchanged from previous GAAP.

The amendments in ASU 2016-02 are effective for public entities for annual reporting periods beginning after December 

15, 2018, and for interim periods within that reporting period. Early application is permitted. Rockies Express is currently 
evaluating the impact of ASU 2016-02.

On October 1, 2015, Rockies Express entered into a $150 million senior unsecured revolving credit facility ("the revolving 
credit facility") with Wells Fargo Bank, N.A., as administrative agent, and a syndicate of lenders, which will mature on January 
31, 2020. The revolving credit facility includes a $75 million sublimit for letters of credit and a $20 million sublimit for swing 
line loans and may be used for working capital and general company purposes. The revolving credit facility also contains an 
accordion feature whereby Rockies Express can increase the size of the credit facility to an aggregate of $200 million, subject 
to receiving increased or new commitments from lenders and the satisfaction of certain other conditions precedent. As of 
December 31, 2016, there were no outstanding borrowings or letters of credit issued under the revolving credit facility.

Borrowings under the credit facility bear interest, at Rockies Express' option, at either (a) a base rate, which will be a rate 

equal to the greatest of (i) the prime rate, (ii) the U.S. federal funds rate plus 0.5% and (iii) a one-month reserve adjusted 
Eurodollar rate plus 1.00% or (b) a reserve adjusted Eurodollar rate, plus, in each case, an applicable margin. For borrowings 
bearing interest based on the base rate, the applicable margin is initially 1.00%, and for loans bearing interest based on the 
reserve adjusted Eurodollar rate, the applicable margin is initially 2.00%. After the first full fiscal quarter, the applicable margin
will range from 0.50% to 1.25% for base rate borrowings and 1.50% to 2.25% for reserve adjusted Eurodollar rate borrowings, 
based upon Rockies Express' total leverage ratio. The unused portion of the credit facility is subject to a commitment fee, 
which ranges from 0.20% to 0.45% based upon Rockies Express' total leverage ratio.

Rockies Express has the option to have the applicable margin determined based on Rockies Express' credit ratings should 

Rockies Express receive an investment grade credit rating from one or more of the ratings agencies in the future. If Rockies 
Express were to make an election to exercise this option, the applicable margin would range from 0.125% to 1.00% for base 
rate borrowings and 1.125% to 2.00% for reserve adjusted Eurodollar borrowings, based on Rockies Express' credit 
ratings. Under such an election, the commitment fee would range from 0.125% to 0.40%, also based on Rockies Express' credit 
ratings.

The revolving credit facility generally requires Rockies Express to comply with various affirmative and negative 
covenants, including a limit on the leverage ratio (as defined in the credit agreement) of Rockies Express and restrictions on:

•

•

•

incurring secured indebtedness;

entering into mergers, consolidations and sales of assets;

granting liens;

168

•

entering into transactions with affiliates; and

• making restricted payments.

As of December 31, 2016, we were in compliance with the covenants required under the revolving credit facility.

Repayment of 3.90% Senior Notes 

The board of directors of Rockies Express approved repayment of the $450 million 3.90% senior notes due April 15, 2015 

("2015 Notes") which was financed through capital contributions by the Members of Rockies Express in proportion to their 
respective ownership interests. The capital contribution was made by each Member of Rockies Express in accordance with 
Section 4.3.1 of Rockies Express' Second Amended and Restated Limited Liability Company Agreement, as amended, and was 
used to repay the 2015 Notes on April 15, 2015.

Fair Value

The following table sets forth the carrying amount and fair value of our long-term debt, which is not measured at fair value

outstanding private placement debt is based upon quoted market prices adjusted for illiquid markets. We are not aware of any 
factors that would significantly affect the estimated fair value subsequent to December 31, 2016.

5. Members' Equity

During the years ended December 31, 2016, 2015, and 2014, Rockies Express made distributions to Members of $471.6

million, $499.0 million, and $361.7 million, respectively.

During the years ended December 31, 2016, 2015, and 2014, Rockies Express received contributions from Members of 

$304.9 million, $733.1 million, and $165.7 million, respectively. Contributions from Members during the year ended 
December 31, 2016 were primarily used to fund the construction and other costs of the Zone 3 Capacity Enhancement project, 
as discussed in Note 9 – Regulatory Matters. Contributions from Members during the year ended December 31, 2015 were 
used to repay the 2015 Notes, as discussed in Note 4 – Financing, fund the construction and other costs of the Zone 3 East-to-
West Project facilities and the Zone 3 Capacity Enhancement project and remaining costs associated with the Seneca Lateral 
Project facilities, and to increase cash on hand for working capital needs. Contributions from Members during the year ended 
December 31, 2014 were used to fund the construction and other costs of the Seneca Lateral Project facilities as well as to 
increase cash on hand for working capital needs.

Additional contributions and distributions were made subsequent to December 31, 2016. For details see Note 11 – 

Subsequent Events.

The future minimum rental commitments are primarily attributable to a 20-year capacity lease agreement with Overthrust 

Pipeline Company ("Overthrust") which commenced on January 1, 2008. The capacity lease provides the right to transport on a 
firm basis 625 MMcf/d of natural gas through Overthrust's system from either the Williams Field Services Opal Processing 
Plant or the TEPPCO Pioneer Processing Plant to the Wamsutter interconnect.

Capital Expenditures

Approximately $54.5 million of Rockies Express' capital expenditure budget for 2017 had been committed for purchases 

of property, plant and equipment at December 31, 2016.

8. Major Customers

During 2016, four non-affiliated shippers accounted for $164.8 million (23%), $82.9 million (12%), $71.4 million (10%),
and $70.4 million (10%), respectively of Rockies Express' total revenues. During 2015, three non-affiliated shippers accounted 
for $187.6 million (24%), $163.0 million (21%), and $104.6 million (13%), respectively of Rockies Express' total revenues. 
During 2014, four non-affiliated shippers accounted for $186.5 million (25%), $165.2 million (22%), $110.2 million (15%),
and $101.4 million (14%), respectively of Rockies Express' total revenues. We attempt to mitigate credit risk by seeking 
collateral or financial guarantees and letters of credit from customers

9. Regulatory Matters

There are currently no proceedings challenging the currently effective transportation rates of Rockies Express. Regulators, 
as well as shippers on Rockies Express, do have rights, under circumstances prescribed by applicable law, to challenge the rates 
Rockies Express charges. Rockies Express can provide no assurance that current rates will remain unchallenged. Any
successful challenge could have a material, adverse effect on Rockies Express' future earnings.

Petition for Declaratory Order – FERC Docket No. RP13-969-000 

In June 2013, in Docket No. RP13-969-000, Rockies Express filed with the FERC a Petition for Declaratory Order which 
sought a ruling that the "most favored nations" or "MFN" provisions contained in Rockies Express' negotiated rate agreements 
("NRAs") with its Foundation and Anchor Shippers would not prevent Rockies Express from providing firm transportation 
service at rates lower than Foundation and Anchor Shippers' rates that (1) have an east-to-west primary path; (2) are for a term 
of one year or longer; and (3) are limited to service in one rate zone and therefore do not utilize all of the same facilities or rate 
zones as the service provided pursuant to the Foundation and Anchor Shipper NRAs. 

In September 2014, the FERC accepted amended contracts with three shippers holding MFN rights on Rockies Express, 
which reflect the terms of settlements between these shippers and Rockies Express. The settlements provide additional clarity 
with respect to the applicability of the settling shippers' MFN rights, sharing by Rockies Express of certain transportation 
revenues, and the withdrawal of the settling shippers from the Petition for Declaratory Order proceeding. Prior to December 
2015, only one shipper with current MFN rights was still a party to the proceeding.

2015 Annual FERC Fuel Tracking Filings - Docket No. RP15-584-000 

On February 27, 2015, Rockies Express made its annual fuel tracker filing with a proposed effective date of April 1, 2015 

in Docket No. RP15-584-000. This filing incorporated the revised fuel and lost and unaccounted-for and power cost tracker 
mechanisms filed in Docket No. RP14-1003. The FERC issued an order accepting the filing on March 26, 2015 and on April 9,
2015, accepted an errata to the February 27, 2015 filing reflecting a corrected rate for the Cheyenne Booster rate (PCT
Reimbursement Charge).

Seneca Lateral Facilities Conversion – FERC Docket No. CP15-102-000 

On March 2, 2015 in Docket No. CP15-102-000, Rockies Express filed with the FERC an application for (1) authorization 

to convert certain existing and operating pipeline and compression facilities located in Noble and Monroe Counties, Ohio 
(Seneca Lateral Facilities described in Docket Nos. CP13-539-000 and CP14-194-000) from Natural Gas Policy Act of 1978 
Section 311 authority to NGA Section 7 jurisdiction, and (2) issuance of a certificate of public convenience and necessity 
authorizing Rockies Express to operate and maintain the Seneca Lateral Facilities. On April 7, 2016, the FERC issued a 
Certificate to Rockies Express granting its requested authorizations. As directed by the FERC, Rockies Express filed revised 
rates for NGA service on the Seneca Lateral, and the Seneca Lateral commenced NGA service on June 1, 2016.

Rockies Express Zone 3 Capacity Enhancement Project – FERC Docket No. CP15-137-000

On March 31, 2015 in Docket No. CP15-137-000, Rockies Express filed with the FERC an application for authorization to 
construct and operate (1) three new mainline compressor stations located in Pickaway and Fayette Counties, Ohio and Decatur 
County, Indiana; (2) additional compressors at an existing compressor station in Muskingum County, Ohio; and (3) certain 
ancillary facilities. The proposed facilities will increase the Rockies Express Zone 3 east-to-west mainline capacity by 0.8 Bcf/
d. Pursuant to the FERC's obligations under the National Environmental Policy Act, FERC staff issued an Environmental 
Assessment for the project on August 31, 2015. On February 25, 2016, the FERC issued a Certificate of Public Convenience 
and Necessity authorizing Rockies Express to proceed with the project. On March 14, 2016, Rockies Express commenced 
construction of the project facilities. The project was placed in-service for the 0.8 Bcf/d on January 6, 2017. 

2016 Annual and Interim FERC Fuel Tracking Filings - Docket Nos. RP16-702 and RP17-240

On March 1, 2016, Rockies Express made its annual fuel tracker filing with a proposed effective date of April 1, 2016 in 

Docket No. RP16-702. The FERC issued an order accepting the filing on March 25, 2016. On December 1, 2016, Rockies 
Express made an interim fuel tracker filing with a proposed effective date of January 1, 2017 in Docket No. RP17-240. The
FERC issued an order accepting the filing on December 29, 2016. The filing reflected a corrected rate for a previous 
inadvertent error made in the allocation of Overthrust, Echo Springs, and Wamsutter fuel between non-expansion and 
expansion volumes during the period from July 2014 through July 2016.

Electric Power Charge Clarification - Docket No. RP17-285

On December 21, 2016, in Docket No. RP17-285, Rockies Express proposed certain revisions to the General Terms and 

Conditions of its tariff to clarify that the electric power costs associated with the operation of gas coolers installed in 
association with the Zone 3 Capacity Enhancement Project (i.e. at both electric and gas powered stations), will be included in 
the Power Cost Tracker. Several shippers submitted comments on the proposal. The FERC issued an order on January 19, 2017 
accepting the proposed revisions permitting the recovery of electric power costs from the operation of both gas and electric 
powered compressor stations, subject to certain clarifications.

10. Legal and Environmental Matters

Legal

In addition to the matters discussed below, Rockies Express is a defendant in various lawsuits arising from the day-to-day 
operations of its business. Although no assurance can be given, Rockies Express believes, based on its experiences to date, that 
the ultimate resolution of such routine items will not have a material adverse impact on its business, financial position, results 
of operations or cash flows.

Rockies Express has evaluated claims in accordance with the accounting guidance for contingencies that it deems both 
probable and reasonably estimable and, accordingly, have recorded no reserve for legal claims as of December 31, 2016 and 
2015.

172

Mineral Management Service Lawsuit 

On June 30, 2009, Rockies Express filed claims against Mineral Management Service, a former unit of the U.S. 

Department of Interior (collectively "Interior") for breach of its contractual obligation to sign transportation service agreements 
for pipeline capacity that it had agreed to take on Rockies Express. The Civilian Board of Contract Appeals ("CBCA") 
conducted a trial and ruled that Interior was liable for breach of contract, but limited the damages Interior was required to pay.
On September 13, 2013, the United States Court of Appeals for the Federal Circuit issued a decision affirming that Interior was 
liable for its breach of contract, but reversing the CBCA's decision to limit damages. The case was remanded to the CBCA for 
the purpose of calculating damages at a hearing. On May 20, 2016, Rockies Express and Interior agreed to resolve the claims in 
this matter in exchange for a $65 million cash payment to Rockies Express. Interior paid the amount due Rockies Express on 
June 23, 2016, at which time Rockies Express recognized a gain on the litigation settlement.

Ultra Resources

In early 2016, Ultra Resources, Inc. ("Ultra") defaulted on its firm transportation service agreement for approximately 0.2

Bcf/d through November 11, 2019. In late March 2016, Rockies Express terminated Ultra's service agreement. On April 14, 
2016, Rockies Express filed a lawsuit against Ultra for breach of contract and damages in Harris County, Texas, seeking 
approximately $303 million in damages and other relief. On April 29, 2016, Ultra and certain of its debtor affiliates filed for 
protection under Chapter 11 of the United States Bankruptcy Code in United States Bankruptcy Court for the Southern District 
of Texas, which operated as a stay of the Harris County state court proceeding.

On January 12, 2017, Rockies Express and Ultra entered into an agreement to settle Rockies Express' approximately $303

million claim against Ultra's bankruptcy estate. The settlement agreement includes Ultra's agreement to: (i) make a cash 
payment to Rockies Express of $150 million in accordance with the plan of reorganization, but no later than October 30, 2017; 
and (ii) enter a new, seven-year firm transportation agreement with Rockies Express commencing December 1, 2019, for west-
to-east service of 0.2 Bcf/d at a rate of approximately $0.37, or approximately $26.8 million annually. The settlement is part of 
Ultra's Chapter 11 reorganization plan, which must be submitted to the U.S. Bankruptcy Court for approval.

Michels Corporation 

On June 17, 2014, Michels Corporation ("Michels") filed a complaint and request for relief against Rockies Express in the 

Court of Common Pleas, Monroe County, Ohio, as a result of work performed by Michels to construct the Seneca Lateral 
Pipeline in Ohio. Michels sought unspecified damages from Rockies Express and asserted claims of breach of contract, 
negligent misrepresentation, unjust enrichment and quantum meruit. Michels also filed notices of Mechanic's Liens in Monroe 
and Noble Counties, asserting $24.2 million as the amount due.

On February 2, 2017, Rockies Express and Michels entered into a binding settlement agreement to resolve the claims 
brought by Michels in exchange for a $10 million cash payment by Rockies Express. The cash payment will be paid promptly 
after entering into the definitive agreement with respect to the settlement.

Environmental, Health and Safety

Rockies Express is subject to a variety of federal, state and local laws that regulate permitted activities relating to air and 
water quality, waste disposal, and other environmental matters. Rockies Express believes that compliance with these laws will 
not have a material adverse impact on its business, cash flows, financial position or results of operations. However, there can be 
no assurances that future events, such as changes in existing laws, the promulgation of new laws, or the development of new 
facts or conditions will not cause Rockies Express to incur significant costs.

11. Subsequent Events

Tallgrass Energy GP, LP, a Delaware limited partnership (“TEGP Partnership”); and

WHEREAS, pursuant to Section 11 of the Prior Agreement, amendment of the Prior Agreement requires a writing signed 

by the parties thereto.

NOW, THEREFORE, the Prior Agreement is amended and restated in its entirety as follows:

1.

2.

Employment. The Company agrees to continue to employ Dehaemers and Dehaemers agrees to continue to be 
employed by the Company as President and Chief Executive Officer upon the terms and conditions of this 
Agreement until such employment is terminated as provided in Section 7.  So long as Dehaemers is employed by 
the Company as its President and Chief Executive Officer, each of the Partnership Entities agrees that Dehaemers 
will also serve as and be appointed President and Chief Executive Officer of each of the Partnership Entities.

Compensation.  For all services rendered by Dehaemers to the Company, the Partnership Entities and each of the 
downstream affiliates of the Partnership Entities (the Partnership Entities and such downstream affiliates, the 
“Constituent Companies”), the Company will pay Dehaemers a base monthly salary of $25,000 ($300,000 if 
annualized), which will accrue and be payable monthly in arrears in accordance with the Company’s general 
payroll practices. All payments made and benefits provided by the Company to Dehaemers under this Agreement
are subject to any applicable withholding and other applicable taxes.

3.

Additional Benefits; Expenses; Liability Insurance.

(a)

Dehaemers will be eligible for additional benefits, by way of insurance, hospitalization and vacations 
normally provided to senior executives of the Company, pursuant to the terms of those plans, programs and 
policies of the Company in effect during his employment by the Company, and such additional benefits, if 
any, as determined by the Board of Managers of Holdings.

(b)

The Company will reimburse Dehaemers for all ordinary and necessary out-of-pocket expenses incurred 
and paid by Dehaemers in the course of the performance of his duties pursuant to this Agreement and 

4.

5.

consistent with the Company’s policies in effect from time to time with respect to travel, entertainment and 
other business expenses, and subject to the Company’s requirements with respect to the manner of approval 
and reporting of these expenses.

(c)

So long as Dehaemers is employed under this Agreement and thereafter so long as Dehaemers is subject to 
any possible claim, the Company and the Partnership Entities will purchase and maintain in effect for the 
benefit of Dehaemers one or more valid and enforceable policies of directors and officers liability 
insurance providing, in all respects, coverage at least as beneficial to Dehaemers as that provided pursuant 
to the insurance policies in place on the date hereof.

Duties.  So long as Dehaemers is employed under this Agreement, Dehaemers will (a) devote his best efforts and 
his entire business time (other than as a result of illness or disability) to further the interests of the Company and 
the Constituent Companies, (b) carry out the reasonable and lawful instructions of the Board of Managers of 
Holdings (other than as a result of illness or disability) with respect to those matters reserved to the Board of 
Managers of Holdings pursuant to Section 8.1 of the Second Amended and Restated Limited Liability Company 
Agreement of Holdings, dated May 11, 2015 (as amended, restated or otherwise modified from time to time, the 
“Holdings LLC Agreement”), (c) truthfully and accurately maintain and preserve the records of the Company and 
the Constituent Companies and make all reports reasonably required by the Board of Managers of Holdings, and 
(d) fully account for all monies and other property of the Company or any of the Constituent Companies that he 
may from time to time have in his custody and deliver the same to the Company or its designee to the extent 
reasonably directed to do so; provided that, so long as it does not materially interfere with his duties, nothing 
herein will preclude Dehaemers from accepting appointment to or continuing to serve on any board of directors 
(or similar governing body) or as trustee of any business (not competing with any of the Constituent Companies) 
or any charitable organization, from engaging in charitable and community activities, from delivering lectures and 
fulfilling speaking engagements, or from directing and managing his personal investments and those of his family.

Covenant Not to Compete.  Dehaemers acknowledges that, during his employment with the Company, he, at the 
expense of the Company and the Constituent Companies, will establish favorable relations with the customers to, 
and regulators of, the Company and the Constituent Companies and will receive and have access to the 
intellectual property and confidential information of the Company and the Constituent Companies. Therefore, in 
consideration of these relationships, his employment with the Company, and to further protect the intellectual 
property and confidential information of the Company and the Constituent Companies, Dehaemers agrees that, 
during the term of his employment by the Company and for a period of one year from and after the voluntary or 
involuntary termination of employment for any or no reason, he will not, directly or indirectly, without the 
express written consent of the Board of Managers of Holdings except when and as requested to do in and about 
the performance of his duties under this Agreement:

(a)

own, manage, operate, control or participate in the ownership, management, operation or control of, or 
have any interest, financial or otherwise, in or act as an officer, director, partner, principal, member,
manager, shareholder, employee, agent, representative, consultant or independent contractor of, or in any 
way assist any person or entity in the conduct of, any business located in or doing business in the area 
where a Constituent Company is engaged or becomes engaged in any business competitive to any business 
engaged in by a Constituent Company during the term of his employment by the Company, including, but 
not limited to, any business that is engaged in the interstate transportation via pipeline of natural gas, 
petroleum or petroleum byproducts; provided, however, that notwithstanding the foregoing, Dehaemers 
may own up to 5% of the outstanding equity securities in any corporation or entity that is listed upon a 
national stock exchange or actively traded in the over-the-counter market; provided, further, that 
notwithstanding the foregoing, Dehaemers may own, directly or indirectly, an ownership interest in the 
general partner of Plains All American Pipeline, L.P. or their affiliates or successors; provided, further, that 
notwithstanding the foregoing, Dehaemers may place or invest money with one or more private equity 
firms (or related investment funds or vehicles) that compete (or own or invest in companies that compete) 
with a Constituent Company so long as Dehaemers does not control or otherwise direct the activities of the 
private equity firm (or related investment funds or vehicles) or control or otherwise direct the investment in 
the competing portfolio company; or

(b)

entice, induce or in any manner influence any person who has an employee or independent contractor 
relationship with the Company or any Constituent Company and with whom Dehaemers had contact, 
directly or indirectly, during the term of his employment to change or end such relationship for the purpose 
of engaging in a business in competition with any business engaged in by the Company or any Constituent 
Company during the term of his employment by the Company or hire any such person.

6.

Specific Performance.  Recognizing that irreparable damage will result to the Company and the Constituent 
Companies in the event of the breach of any of the foregoing covenants and assurances by Dehaemers contained 
in Section 5, and that the Company’s remedies at law for any such breach or threatened breach will be inadequate, 
the Company, in addition to such other remedies that may be available to it, will be entitled to an injunction, 
including a mandatory injunction, to be issued by any court of competent jurisdiction ordering compliance with 
this Agreement or enjoining and restraining Dehaemers, and each and every person and entity acting in concert or 
participation with him, from the continuation of the breach. The Company will not be required to obtain a bond 
in an amount greater than $1,000. The covenants and obligations of Dehaemers set forth in Section 5 are in 
addition to and not in lieu of or exclusive of any other obligations and duties of Dehaemers to the Company,
whether express or implied in fact or in law.

7.

Termination.

(a)

(b)

(c)

Dehaemers’s employment by the Company will terminate immediately (unless otherwise determined by the 
Board of Managers of Holdings) upon the occurrence of any of the following: (1) the death, mental or 
physical incapacity or inability to perform the essential functions of his job for a consecutive period of 90 
days or a non-consecutive period of 120 days during any 12-month period, as reasonably determined by the 
Board of Managers of Holdings after consultation with an independent physician selected by the Company 
(such periods to be extended if appropriate as a reasonable accommodation for a disability); or (2) the 
winding up and final distribution of the assets of each of Development, the MLP and TEGP Partnership.

Dehaemers’s employment by the Company will terminate on the date specified in a notice of termination 
(which may not be less than 30 days after the date of the notice) from a majority of the members of the 
Board of Managers of Holdings (excluding Dehaemers or any of his designees), which may be sent at the 
discretion of a majority of the members of the Board of Managers of Holdings (excluding Dehaemers or 
any of his designees), as a result of the occurrence of any of the following: (1) Dehaemers and his 
Permitted Transferees (as defined in the Holdings LLC Agreement) cease to control Tallgrass KC, LLC; or 
(2) Dehaemers and his Permitted Transferees cease to have direct or indirect beneficial ownership of at 
least 12.5% of the total Common GP Interests (as such term is defined in the Holdings LLC Agreement).

The Company may terminate Dehaemers’s employment for Cause or without Cause.  “Cause” means: (1) 
his conviction of, or plea of nolo contendere to, any crime or offense constituting a felony under applicable 
law, other than any motor vehicle violations for which no custodial penalty is imposed; (2) his commission 
of fraud or embezzlement against the Company or any Constituent Company; (3) gross neglect by 
Dehaemers of, or gross or willful misconduct by Dehaemers in connection with the performance of, his 
duties to the Company that, if curable, is not cured within 30 days after a written notice of such gross 
neglect, or gross or willful misconduct, specifically identifying the gross neglect or misconduct, is 
delivered by a majority of the members of the Board of Managers of Holdings (excluding Dehaemers or 
any of his designees) to Dehaemers; (4) Dehaemers willfully fails or refuses to carry out the reasonable and 
lawful instructions of the Board of Managers of Holdings (other than as a result of illness or disability) 
with respect to those matters reserved to the Board of Managers of Holdings pursuant to Section 8.1 of the 
Holdings LLC Agreement, and, in each case, such failure or refusal has continued for a period of 30 
calendar days following written notice from the majority of the members of the Board of Managers of 
Holdings (excluding Dehaemers or any of his designees); (5) his failure to perform the duties and 
responsibilities of his office as his primary business activity, provided that, so long as it does not materially 
interfere with his duties on behalf of the Company, nothing herein will preclude Dehaemers from accepting 
appointment to or continuing to serve on any board of directors (or similar governing body) or as trustee of 
any business corporation (not competing with any Constituent Company) or any charitable organization,
from engaging in charitable and community activities, from delivering lectures and fulfilling speaking 
engagements, or from directing and managing his personal investments and those of his family; (6) a 
judicial determination that he has breached his fiduciary duties with respect to the Company or any 
Constituent Company; or (7) his willful and material breach of his obligations in the Holdings LLC 
Agreement (in his capacity as an officer and not in his capacity as a Member), his obligations in the Second 
Amended and Restated Limited Liability Company Agreement of Tallgrass Equity, dated as of May 12, 
2015, as amended, restated or otherwise modified from time to time (in his capacity as an officer and not in 
his capacity as a Member), his obligations in the Second Amended and Restated Limited Liability 
Company Agreement of MLP GP, dated as of May 17, 2013, as amended, restated or otherwise modified 
from time to time (in his capacity as an officer and not in his capacity as a Member), or his obligations in 
the Amended and Restated Limited Liability Company Agreement of TEGP Management, dated May 12, 
2015, as amended, restated or otherwise modified from time to time (in his capacity as an officer and not in 
his capacity as a Member) (such agreements, collectively, the “Organizational Documents”), including 

willfully causing any Partnership Entity to take any material action prohibited by the Organizational
Documents, that Dehaemers failed to cure, if curable, within 30 days following written notice thereof, 
specifically identifying such willful and material breach, having been delivered to Dehaemers by a majority 
of the members of the Board of Managers of Holdings (excluding Dehaemers or any of his designees).

(d)

Dehaemers may terminate his employment with the Company with good reason or without good reason. A
“Resignation for Good Reason” means his resignation for good reason (as defined below) if (x) he provides 
written notice to the Company describing in reasonable detail the event and stating that his employment 
will terminate upon a specified date in such notice (“Good Reason Termination Date”), which date is not 
earlier than 30 days after the date such notice is provided to the Company (“Notice Delivery Date”) and not 
later than 90 days after the Notice Delivery Date and (y) the Company does not remedy the event prior to 
the Good Reason Termination Date.  For purposes of this Agreement, Dehaemers has “good reason” if 
there occurs without his prior written consent:

a material diminution of his duties and responsibilities to the Company or any Constituent 
Company to a level inconsistent with those of a chief executive officer;

a material reduction in his cash compensation or a material reduction in the aggregate welfare 
benefits provided to him (not including any reduction related to a broader compensation or benefit 
reduction that is not limited to him specifically);

a willful or intentional breach of this Agreement by the Company; or

a willful or intentional breach of a material provision of any of the Organizational Documents by 
any Partnership Entity or the Primary Investors (as defined in the Holdings LLC Agreement) that 
has a material and adverse effect on Dehaemers.

(e)

If (1) Dehaemers’s employment with the Company is terminated pursuant to Sections 7(a) or 7(b), (2) the 
Company terminates his employment for Cause or (3) Dehaemers terminates his employment other than as 
a result of a Resignation for Good Reason, the Company will pay or provide to him:

(i)

(ii)

such unpaid salary as Dehaemers has earned up to the date of his termination; and

the other benefits and other amounts due him under Section 3 or as otherwise required by 
applicable law, as he has earned up to the date of his termination.

(f)

If (1) the Company terminates Dehaemers’s employment without Cause or (2) Dehaemers terminates his 
employment as a result of a Resignation for Good Reason, the Company will pay or provide to him:

(i)

(ii)

(iii)

such unpaid salary as Dehaemers has earned up to the date of his termination;

an amount equal to $900,000, payable as a lump sum within 60 days after the termination of 
employment; and

such other benefits and other amounts due him under Section 3 or as otherwise required by 
applicable law, as he has earned up to the date of his termination.

(g)

(h)

Except as provided in Section 7(i), any payment under this Section 7(f) must be made within 60 days after 
the termination of his employment; provided, however, if the termination of his employment is not a 
“separation from service” as described in Treas. Reg. § 1 .409A- 1(h) (a “Section 409A Separation”), such 
payment will be delayed until his Section 409A Separation.

As a condition to receiving the termination payments and benefits provided in this Section 7, Dehaemers 
will execute and deliver to the Company a release, in a form reasonably satisfactory to the Company,
releasing all claims arising out of his employment (other than enforcement of this Agreement, his rights 
under any of the Company’s incentive compensation and employee benefit plans and programs to which 
Dehaemers is entitled under this Agreement, and any claim for any tort for personal injury not arising out 
of or related to this termination).

So long as Dehaemers is an employee of the Company and thereafter (including after the termination of his 
employment), he will not make any disparaging comment in any format, whether written, electronic or 
oral, to any client, customer, account, supplier, service provider, agency, regulator, employee, the media, or 
any other person or entity regarding the Company or any Constituent Company or any of their clients, 
customers, accounts, suppliers, service providers, employees, agents, regulators, officers or directors or 
otherwise relating to the business of the Company or any Constituent Company.

(i)

(j)

If Dehaemers is a “Specified Employee” (as defined under Section 409A of the Internal Revenue Code of 
1986, as amended (“Code”)) as of the date of his termination of employment, as determined by the 
Company, and any equity security of the Company or any Constituent Company is publicly traded on an 
established securities market or otherwise, the payment of any amount under this Agreement on account of 
his Section 409A Separation that is deferred compensation subject to the provisions of Code Section 409A
and not otherwise excluded from Code Section 409A, will not be paid until the later of the first business 
day that is six months after the date after his Section 409A Separation or the date the payment is otherwise 
payable under this Agreement (the “Delay Period”).  Upon the expiration of the Delay Period, all payments 
and benefits delayed will be paid or reimbursed to Dehaemers in a lump sum, without interest, and any 
remaining payments due under this Agreement will be paid or provided in accordance with the normal 
payment dates specified herein.

All reimbursement and in-kind benefits provided pursuant to this Agreement will be made in accordance 
with Treas. Reg. § 1 .409A-3(i)(1)(iv) such that any reimbursement or in-kind benefits will be deemed 
payable at a specified time or on a fixed schedule relative to a permissible payment event.  Specifically, (1) 
the amounts reimbursed and in-kind benefits provided under this Agreement, other than with respect to 
medical benefits, during Dehaemers’s taxable year may not affect the amount reimbursed or in-kind benefit 
provided in any other taxable year, (2) the reimbursement of an eligible expense will be made on or before 
the last day of his taxable year following the taxable year in which the expense was incurred, and (3) the 
right to reimbursement or an in-kind benefit is not subject to liquidation or exchange for another benefit.

8.

9.

Cooperation Regarding Litigation.  So long as Dehaemers is an employee of the Company and thereafter for a 
period of five years (including after the termination of his employment), Dehaemers will reasonably cooperate 
with the Company and any Constituent Company by making himself available to testify on behalf of the 
Company or any Constituent Company, in any action, suit, or proceeding (whether civil, criminal, administrative 
or investigative) and reasonably assist the Company or any Constituent Company in any such action, suit, or 
proceeding, by providing information and meeting and consulting with the Board of Managers of Holdings or its 
representatives or counsel, or representatives or counsel to the Company or any Constituent Company, as 
requested. The Company will promptly reimburse Dehaemers for all reasonable expenses incurred by Dehaemers 
in connection with his provision of testimony or assistance.

No Conflict.  Dehaemers represents and warrants to the Company and each Partnership Entity that neither the 
execution nor delivery of this Agreement, nor the performance of his obligations under this Agreement will 
conflict with, or result in a breach of, any term, condition, or provision of, or constitute a default under, any 
obligation, contract, agreement, covenant or instrument to which he is a party or under which he is bound, 
including, without limitation, the breach by Dehaemers of a fiduciary duty to any former employers.

10. Waiver of Breach.  Failure of the Company or any Partnership Entity to demand strict compliance with any of the 
terms, covenants or conditions hereof will not be deemed a waiver of the term, covenant or condition, nor will any 
waiver or relinquishment by the Company or any Partnership Entity of any right or power under this Agreement at 
any one time or more times be deemed a waiver or relinquishment of the right or power at any other time or times.

11.

12.

Entire Agreement; Amendment. This Agreement cancels and supersedes all previous agreements other than the 
Confidentiality Agreement and Assignment of Inventions, by and between Dehaemers and the Company, entered 
into in connection with his employment by the Company (the “Confidentiality Agreement”) relating to the subject 
matter of this Agreement, written or oral, between the parties, including, without limitation, the Prior Agreement.
This Agreement and the Confidentiality Agreement contain the entire understanding of the parties with respect to 
the subject matter hereof and may not be amended, modified or supplemented in any manner whatsoever except 
as otherwise provided herein or in writing signed by each of the parties.

Potential Unenforceability of any Provision.  If a final judicial determination is made that any provision of this 
Agreement is an unenforceable restriction against Dehaemers, the provisions of this Agreement will be rendered 
void only to the extent that a judicial determination finds the provisions unenforceable, and the unenforceable 
provisions will automatically be reconstituted and become a part of this Agreement, effective as of the date of this 
Agreement, to the maximum extent in favor of the Company and the Partnership Entities that is lawfully 
enforceable. A judicial determination that any provision of this Agreement is unenforceable will not render the 
entire Agreement unenforceable, but rather this Agreement will continue in full force and effect absent any 
unenforceable provision to the maximum extent permitted by law.

13.

Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only 
and do not restrict or otherwise modify any of the terms or provisions of this Agreement.

Counterparts. This Agreement may be executed in any number of counterparts, each of which will be deemed to 
be an original and all of which constitute one agreement that is binding upon each of the parties, notwithstanding 
that all parties are not signatories to the same counterpart.

Consent to Jurisdiction and Venue. The parties hereby submit to the exclusive jurisdiction of the District Court 
for Johnson County, Kansas or the United States District Court for the District of Kansas in any action or 
proceeding arising out of or relating to this Agreement, including any appeal and any action for enforcement or 
recognition of any judgment relating thereto, and the parties hereby irrevocably agree that all claims in respect of 
such action or proceeding may not be heard or determined in any court or before any panel other than the District 
Court for Johnson County, Kansas or the United States District Court for the District of Kansas. A final judgment 
in any such action or proceeding will be conclusive and may be enforced in any other jurisdictions by suit on the 
judgment or in any manner provided by law. The parties hereby irrevocably waive, to the fullest extent they may 
legally and effectively do so, any objection they may have to the laying of venue of any suit, action or proceeding 
arising out of or relating to this Agreement or the transactions contemplated hereby in the District Court for 
Johnson County, Kansas or the United States District Court for the District of Kansas. The parties hereby 
irrevocably waive, to the fullest extent they may legally and effectively do so, the defense of an inconvenient 
forum to the maintenance of any suit, action or proceeding in any such court. The parties irrevocably consent to 
service of process in any suit, action or proceeding in any manner provided by law.

Expenses.  If either party brings any legal action or other proceeding to enforce or interpret any of the rights, 
obligations or provisions of this Agreement, or because of a dispute, breach or default in connection with any of 
the provisions of this Agreement, the prevailing party is entitled to recover from the non-prevailing party 
reasonable attorneys’ fees and all other costs in such action or proceeding in addition to, but without duplication, 
any other relief to which the prevailing party may be entitled.

No Mitigation; No Offset.  If Dehaemers’s employment is terminated, he will be under no obligation to seek other 
employment and amounts due him under this Agreement will not be offset by any remuneration attributable to any 
subsequent employment that he may obtain.

Deferred Compensation. This Agreement is intended to meet the requirements of Section 409A of the Code and 
will be administered in a manner that is intended to meet those requirements and will be construed and interpreted 
in accordance with such intent. To the extent that an award or payment, or the settlement or deferral thereof, is 
subject to Section 409A of the Code, except as Dehaemers and the Board of Managers of Holdings otherwise 
determine in writing, the award will be granted, paid, settled or deferred in a manner that will meet the 
requirements of Section 409A of the Code, including regulations or other guidance issued with respect thereto, 
such that the grant, payment, settlement or deferral will not be subject to the excise tax applicable under Section 
409A of the Code. Any provision of this Agreement that would cause the award or the payment, settlement or 
deferral thereof to fail to satisfy Section 409A of the Code will be amended to comply with Section 409A of the 
Code on a timely basis, which may be made on a retroactive basis, in accordance with regulations and other 
guidance issued under Section 409A of the Code.

(1) TEP closed the acquisition of Trailblazer on April 1, 2014 and the acquisition of a controlling 33.3% membership interest 

in Pony Express effective September 1, 2014. As the acquisitions of Trailblazer and the initial 33.3% of Pony Express were 
considered transactions between entities under common control, and changes in reporting entity, financial information 
presented subsequent to November 13, 2012 and prior to the respective acquisition dates has been recast to include 
Trailblazer and the initial 33.3% of Pony Express. TEP closed the acquisition of an additional 33.3% membership interest 
in Pony Express effective March 1, 2015, which represents a transaction between entities under common control and an 
acquisition of noncontrolling interests. As a result, financial information for periods prior to March 1, 2015 have not been 
recast to reflect the additional 33.3% membership interest.

(2) For purposes of determining the ratio of earnings to fixed charges, earnings are defined as pretax income or loss from 

continuing operations before earnings from unconsolidated affiliates, plus fixed charges, plus distributed earnings from 
unconsolidated affiliates, less capitalized interest. Fixed charges consist of interest expensed, capitalized interest, 
amortization of deferred loan costs, and an estimate of the interest within rental expense.

(3) As a result of the net loss for the period from November 12, 2012 to December 31, 2012, the ratio of earnings to fixed 

charges was less than 1:1. TEP would have needed to generate additional earnings of $2.6 million to achieve an earnings to 
fixed charges ratio of 1:1 for the period from November 12, 2012 to December 31, 2012.
