Glossary of Common Industry and Measurement Terms

Bakken oil production area: Montana and North Dakota in the United States and Saskatchewan and Manitoba in Canada.

Barrel (or bbl): ~~forty two~~forty-two U.S. gallons.

Base Gas (or Cushion Gas): the volume of gas that is intended as permanent inventory in a storage reservoir to maintain adequate pressure and deliverability rates.

BBtu: one billion British Thermal Units.

Bcf: one billion cubic feet.

British Thermal Units or Btus: the amount of heat energy needed to raise the temperature of one pound of water by one degree Fahrenheit.

Commodity sensitive contracts or arrangements: contracts or other arrangements, including tariff provisions, that are directly ~~expose our cash flows~~tied to increases and decreases in the price of commodities such as crude oil, natural gas and NGLs. Examples are Keep Whole Processing Contracts and Percent of Proceeds Processing Contracts, as well as pipeline loss allowances on our pipelines.

Condensate: aan NGL with a low vapor pressure, mainly composed of propane, butane, pentane and heavier hydrocarbon fractions.

Contract barrels: barrels of crude oil that our customers have contractually agreed to ship in exchange for firm service assurance of capacity and deliverability to delivery points.

Delivery point: any point at which product in a pipeline is delivered to or for the account of a customer.

Dry gas: a gas primarily composed of methane and ethane where heavy hydrocarbons and water either do not exist or have been removed through processing.

Dth: a dekatherm, which is a unit of energy equal to 10 therms or one million British thermal units.

End-user markets: the ultimate users and consumers of transported energy products.

EPA: the United States Environmental Protection Agency.

FERC: Federal Energy Regulatory Commission.

Firm fee contracts: ~~firm fee~~ contracts or other arrangements, including tariff provisions, that generally obligate our customers to pay a fixed recurring charge to reserve an agreed upon amount of capacity and/or deliverability on our assets, regardless if the contracted capacity is actually used by the customer. Such contracts are also commonly known as "take-or-pay" contracts.

Firm services: services pursuant to which customers receive firm assurances regarding the availability of capacity and/or deliverability of natural gas, crude oil or other hydrocarbons or water on our assets up to a contracted amount.

Fractionation: the process by which NGLs are further separated into individual, typically more valuable components including ethane, propane, butane, isobutane and natural gasoline.

GAAP: generally accepted accounting principles in the United States of America.

GHGs: greenhouse gases.

Header system: networks of medium-to-large-diameter high pressure pipelines that connect local gathering systems to large diameter high pressure long-haul transportation pipelines.

Interruptible services: services pursuant to which customers receive limited, or no, assurances regarding the availability of capacity and deliverability in our assets.

Keep Whole Processing Contracts: natural gas processing contracts in which we are required to replace the Btu content of the NGLs extracted from inlet wet gas processed with purchased dry natural gas.

Line fill: the volume of oil, in barrels, in the pipeline from the origin to the destination.

Liquefied natural gas or LNG: natural gas that has been cooled to minus 161 degrees Celsius for transportation, typically by ship. The cooling process reduces the volume of natural gas by 600 times.

Local distribution company or LDC: LDCs are involved in the delivery of natural gas to ~~consumers~~end users within a specific geographic area.

Long-term: with respect to any contract, a contract with an initial duration greater than one year.

MMBtu: one million British Thermal Units.

Mcf: one thousand cubic feet.

MDth: one thousand dekatherms.

MMcf: one million cubic feet.

Natural gas liquids or NGLs: those hydrocarbons in natural gas that are separated from the natural gas as liquids through the process of absorption, condensation, adsorption or other methods in natural gas processing or cycling plants. Generally, such liquids consist of propane and heavier hydrocarbons and are commonly referred to as lease condensate, natural gasoline and liquefied petroleum gases. Natural gas liquids include natural gas plant liquids (primarily ethane, propane, butane and isobutane) and lease condensate (primarily pentanes produced from natural gas at lease separators and field facilities).

Natural Gas Processing: the separation of natural gas into pipeline-quality natural gas and a mixed NGL stream.

Non-contract barrels (or walk-up barrels): barrels of crude oil that our customers ship based solely on availability of capacity and deliverability with no assurance of future capacity.

No-notice service: those services pursuant to which customers receive the right to transport or store natural gas on assets outside of the daily nomination cycle without incurring penalties.

NYMEX: New York Mercantile Exchange.

Park and loan services: those services pursuant to which customers receive the right to store natural gas in (park), or borrow gas from (loan), our ~~facilities on a seasonal basis.~~facilities.

Percent of Proceeds Processing Contracts: natural gas processing contracts in which we process our customer's natural gas, sell the resulting NGLs and residue gas and divide the proceeds of those sales between us and the customer. Some percent of proceeds contracts may also require our customers to pay a monthly reservation fee for processing capacity.

PHMSA: the United States Department of Transportation's Pipeline and Hazardous Materials Safety Administration.

Play: a proven geological formation that contains commercial amounts of hydrocarbons.

Produced water: all water removed from a well as a byproduct of the production of hydrocarbons and water removed from a well in connection with operations being conducted on the well, including naturally occurring water in the recovery formation, flow back water recovered during completion and fracturing operations and water entering the recovery formation through water flooding techniques.

Receipt point: the point where a product is received by or into a gathering system, processing facility, or transportation pipeline.

Reservoir: a porous and permeable underground formation containing an individual and separate natural accumulation of producible hydrocarbons (such as crude oil and/or natural gas) which is confined by impermeable rock or water barriers and is characterized by a single natural pressure system.

Residue gas: the natural gas remaining after being processed or treated.

Shale gas: natural gas produced from organic (black) shale formations.

Tailgate: the point at which processed natural gas and NGLs leave a processing facility for transportation to end-user markets.

TBtu: one trillion British Thermal Units.

Tcf: one trillion cubic feet.

Throughput: the volume of products, such as crude oil, natural gas or water, transported or passing through a pipeline, plant, terminal or other facility during a particular period.

Uncommitted shippers (or walk-up shippers): customers that have not signed long-term shipper contracts and have rights under the FERC tariff as to rates and capacity allocation that are different than long-term committed shippers.

Volumetric fee contracts: ~~volumetric fee~~ contracts or other arrangements, including tariff provisions, that generally obligate a customer to pay fees based upon the extent to which such customer utilizes our assets for midstream energy services. Unlike firm fee contracts, under volumetric fee contracts our customers are not generally required to pay a charge to reserve an agreed upon amount of capacity and/or deliverability.

Wellhead: the equipment at the surface of a well that is used to control the well's pressure; also, the point at which the hydrocarbons and water exit the ground.

Working gas: the volume of gas in the storage reservoir that is in addition to the cushion or base gas. It may or may not be completely withdrawn during any particular withdrawal season. Conditions permitting, the total working capacity could be used more than once during any season.

Working gas storage capacity: the maximum volume of natural gas that can be cost-effectively injected into a storage facility and extracted during the normal operation of the storage facility. Effective working gas storage capacity excludes base gas and non-cycling working gas.

X/d: the applicable measurement metric per day. For example, MMcf/d means one million cubic feet per day.

Financial results for all prior periods have been recast to reflect the operations of the Predecessor Entities. Predecessor Equity as presented in the condensed consolidated financial statements represents the capital account activity of Terminals Predecessor and NatGas Predecessor prior to January 1, 2017. For additional information regarding these acquisitions, see Note 3 – Acquisitions.

2. Summary of Significant Accounting Policies

Basis of Presentation

These condensed consolidated financial statements and related notes for the three ~~and nine~~ months ended ~~September 30,~~March 31, 2017 and 2016 ~~and 2015~~ 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") for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The year-end balance sheet data was derived from audited financial statements but does not include all disclosures required by GAAP for annual periods. The condensed consolidated financial statements for the three ~~and nine~~ months ended ~~September 30,~~March 31, 2017 and 2016 ~~and 2015~~ include all normal, recurring adjustments and disclosures that we believe are necessary for a fair statement of the results for the interim periods. 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.

Our financial results for the three ~~and nine~~ months ended ~~September 30, 2016~~March 31, 2017 are not necessarily indicative of the results that may be expected for the full year ending December 31, ~~2016.~~2017. The accompanying condensed consolidated interim financial statements should be read in conjunction with our audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, ~~2015~~2016 ("~~2015~~2016 Form 10-K") filed with the United States Securities and Exchange Commission (the "SEC") on February ~~17, 2016.~~15, 2017.

The condensed consolidated financial statements include the accounts of TEP and its subsidiaries and controlled affiliates. Significant intra-entity items have been eliminated in the presentation. 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 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~~As further discussed in Note 3 – Acquisitions, TEP closed the acquisition of Terminals and NatGas on January 1, 2017. As the acquisitions of Terminals and NatGas are considered transactions between entities under common control, and a change in reporting entity, ~~("VIE") is a legal entity that possesses any~~the financial information presented has been recast to include Terminals and NatGas for all periods presented. Net equity distributions of the ~~following characteristics: an insufficient amount~~Predecessor Entities included in the condensed consolidated financial statements represent transfers of cash as a result of TD's centralized cash management system prior to January 1, 2017 for Terminals and NatGas, under which cash balances were swept daily and recorded as loans from the subsidiaries of TD. These loans were then periodically recorded as equity ~~at risk to finance its activities, equity owners who do not have the power to direct the significant activities~~distributions.

The accompanying condensed consolidated financial statements of TEP include historical cost-basis accounts 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 returnsassets and liabilities of the ~~entity. Companies~~Predecessor Entities for the periods prior to January 1, 2017, the date TEP acquired Terminals and NatGas from TD, and include charges from TD for direct costs and allocations of indirect corporate overhead. Management believes that the allocation methods are ~~required to consolidate~~reasonable, and that the allocations are representative of costs that would have been incurred on a ~~VIE if they are its primary beneficiary, which is the enterprise that has a variable interest that could be significant to the VIE~~stand-alone basis. TEP and the ~~power to direct~~Predecessor Entities are all considered "entities under common control" as defined under GAAP and, as such, the ~~activities that most significantly impact~~transfers between the entity's economic performance. We have presented separately in our condensed 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 obligationsentities 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.assets and liabilities have been recorded by TEP at historical cost.

Use of Estimates

Certain amounts included in or affecting these condensed 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.

Accounting ~~Pronouncements Not Yet~~Pronouncement Recently 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 the first half of 2016, the FASB has issued a series of subsequent updates to the revenue recognition guidance in Topic 606, including 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, and ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients.

The amendments in ASU 2014-09, ASU 2016-08, ASU 2016-10, and ASU 2016-12 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. In light of this recently issued accounting guidance, we have started the process of reviewing our existing revenue contracts. Due to the early stage of this process, we are currently not in a position to estimate the impact the guidance will have on our consolidated financial statements. 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 as of January 1, 2018 through a cumulative adjustment to equity. Consolidated revenues for periods prior to January 1, 2018 would not be revised.

~~ASU No. 2015-11, "Inventory (Topic 330): Simplifying the Measurement of Inventory"~~

In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330), Simplifying the Measurement of Inventory. ASU 2015-11 establishes a "lower of cost and net realizable value" model for the measurement of most inventory balances. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.

The amendments in ASU 2015-11 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 2015-11, but do not anticipate a material impact on our consolidated financial statements.

~~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.

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~~adopted the ~~impact~~guidance in ASU 2016-09 effective January 1, 2017 and made a policy election to account for forfeitures when they occur. The adoption of ASU 2016-09 ~~but do~~did not ~~anticipate~~have a material impact on our consolidated financial statements.

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.

Through the contract review process currently underway, management has identified several areas of potential impact, including the accounting for non-cash consideration, particularly in our Crude Oil Transportation & Logistics and Processing & Logistics segments, and the timing of revenue recognition with respect to deficiency payments received in our Crude Oil Transportation & Logistics segment. We will continue to conduct our contract review process throughout 2017 and, as a result, additional 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. ~~2016-15, "Statement of Cash Flows~~2016-02, "Leases (Topic ~~230), Classification of Certain Cash Receipts and Cash Payments"~~842)"

In ~~August~~February 2016, the FASB issued ASU No. ~~2016-15, Statement~~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 ~~Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 provides explicit guidance on~~a lease as well as certain scope exceptions. The changes primarily impact lessee 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, proceedswhile lessor accounting is largely unchanged 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.previous GAAP.

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 is 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. Acquisitions

Acquisition of ~~a 25%~~an Additional 24.99% Membership Interest in Rockies Express ~~Pipeline LLC~~

On March ~~29, 2016, TD's indirect wholly owned subsidiary~~31, 2017, TEP, TD, and Rockies Express Holdings, LLC, ~~("REX Holdings") signed~~entered into a ~~purchase agreement (the "REX~~definitive Purchase ~~Agreement")~~and Sale Agreement, pursuant to which TEP acquired an additional 24.99% membership interest in Rockies Express from TD in exchange for cash consideration of $400 million. Together with the 25% membership interest in Rockies Express that TEP acquired from a unit of Sempra U.S. Gas and Power ~~("Sempra") to acquire Sempra's 25%~~on May 6, 2016, this transaction increases TEP’s aggregate membership interest in Rockies Express ~~for cash consideration of $440 million, subject~~ to ~~adjustment under the REX Purchase Agreement.~~49.99%.

On April 28, 2016, we announced that TD offered TEP the right to assume the rights and obligations of REX Holdings under the REX Purchase Agreement. On May 6, 2016, TEP REX Holdings, LLC ("TEP REX"), an indirect wholly-owned subsidiary of TEP, 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 REX Purchase Agreement and, in exchange, TEP REX assumed allThe transfer of the ~~rights and obligations of REX Holdings under the REX Purchase Agreement.

As a result of ~~May 6, 2016,~~the common control nature of the transaction, the 24.99% membership interest in Rockies Express was transferred to the Partnership at TD's historical carrying amount, including the remaining unamortized basis difference driven by the difference between the fair value of ~~our~~the investment ~~in Rockies Express of $436.0 million~~ and the book value of the underlying ~~net~~ assets and liabilities on November 13, 2012, the date of ~~approximately $840.7 million results~~acquisition by TD. For additional information, see Note 7 – Investments in aUnconsolidated Affiliates.

As of March 31, 2017, the negative basis difference ofcarried over from TD was approximately ~~$404.7~~$386.8 million. ~~The basis difference has been 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 associated with the recently acquired 24.99% membership interest in Rockies Express at ~~September 30, 2016~~March 31, 2017 was allocated as follows:


	Basis Difference			Amortization Period	Basis Difference			Amortization Period
	(in thousands)				(in thousands)
Long-term debt	$	7,878		2 - 25 years	$	19,504		2 - 25 years

Total basis difference	$	(399,109	)		$	(386,797	)

During the period from May 6, 2016 to September 30, 2016, we recognized equity in earnings from Rockies Express of $35.4 million, inclusive of the amortization of the negative basis difference discussed above, and received distributions from and made contributions to Rockies Express of $51.5 million and $35.5 million, respectively.

Acquisition of ~~Additional 31.3% Membership Interest in Pony Express~~Tallgrass Terminals, LLC and Tallgrass NatGas Operator, LLC

Effective January 1, ~~2016, TEP~~2017, we acquired ~~an additional 31.3%~~100% of the issued and outstanding membership ~~interest~~interests in ~~Pony Express~~Terminals and 100% of the issued and outstanding membership interests in ~~exchange~~NatGas from TD for total 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$140 million. The transaction increased our aggregate membership interest in Pony Express to 98.0%. 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 8 – ~~Risk Management,~~ on July 21, 2016, we partially exercised the option covering 3,563,146 of the common units. On October 31, 2016, we partially exercised the option covering 1,251,760 of the common units, leaving 1,703,094 remaining common units subject to the call option as of November 2, 2016. As a result of the partial exercise on July 21, 2016, TEP derecognized a portion of the derivative asset balance, recognizing approximately $25.9 million through equity during the nine months ended September 30, 2016, as discussed further in Note 10 – ~~Partnership Equity and Distributions~~.

~~TEP Acquisition of BNN Western, LLC~~

On December 16, 2015, Whiting Oil and Gas Corporation ("Whiting"), BNN Redtail, LLC ("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.

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.

~~7. Goodwill~~

~~Annual Goodwill Impairment Analysis~~

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.

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. Unpredictable events or deteriorating market or operating conditions could result in a future change to the discounted cash flow models and cause impairments in the future. We continue to monitor potential impairment indicators to determine if a triggering event occurs and will perform additional goodwill impairment analyses as necessary.

8. 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.

~~Exercise of~~

Call Option Derivative

OnAs part of our acquisition of an additional 31.3% membership interest in Pony Express effective January 1, 2016, TD granted us an 18 month call option at an exercise price of $42.50 per common unit covering the 6,518,000 common units issued to TD as a portion of the consideration. In July ~~21,~~2016 and October 2016, we partially exercised the call option ~~granted by TD in January 2016 as discussed in Note 3 –~~ ~~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 ~~$151.4 million. On October 31, 2016, we partially exercised the call option again covering an additional 1,251,760 common units for a cash payment of $53.2~~$72.4 million. These common units were deemed canceled upon the exercise of the call option and as of ~~such~~the applicable exercise date were no longer issued and outstanding. ~~As of November 2, 2016, 1,703,094 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 iswas 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 September 30, 2016, the fair value of~~The maximum potential exposure to credit losses on our crude oil and natural gas derivative contracts ~~were a liability, resulting in no credit exposure from TEP's counterparties as of that date.~~at March 31, 2017 was:

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.

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 iswas 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 iswas classified within Level 2 of the fair value hierarchy as the value iswas 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 ~~September 30,~~March 31, 2017 and December 31, 2016 based on the fair value hierarchy established by the Codification:

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 5.50% senior notes due 2024 (the "2024 Notes"). ~~TEP used the net proceeds of the offering to repay outstanding borrowings under its existing senior secured 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 ~~September 30, 2016,~~March 31, 2017, we ~~are~~were in compliance with the covenants required under the 2024 Notes.

Revolving Credit Facility

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 from $1.1 billion 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.

The following table sets forth the available borrowing capacity under the revolving credit facility as of ~~September 30, 2016~~March 31, 2017 and December 31, ~~2015:~~2016:

⁽¹⁾	~~As of October 31, 2016, our outstanding borrowings under the revolving credit facility were approximately $1.003 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 ~~September 30, 2016,~~March 31, 2017, we are in compliance with the covenants required under the revolving credit facility.

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 ~~September 30, 2016,~~March 31, 2017, the weighted average interest rate on outstanding borrowings under the revolving credit facility was ~~2.28%~~2.95%. During the ~~nine~~three months ended ~~September 30, 2016,~~March 31, 2017, our weighted average effective interest rate, including the interest on outstanding borrowings under the revolving credit facility, commitment fees, and amortization of deferred financing costs, was ~~2.72%~~3.12%.

The long-term debt borrowed under the revolving credit facility is carried at amortized cost. As of ~~September 30, 2016~~March 31, 2017 and December 31, ~~2015,~~2016, 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 ~~September 30, 2016.~~March 31, 2017.

10. Partnership Equity and Distributions

Equity Distribution Agreements

~~On October~~As of March 31, ~~2014,~~2017, we ~~entered into an~~had active equity distribution ~~agreement~~agreements 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 toand $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 netNet cash proceeds from any sale of the common units may be used for general partnership purposes, which ~~may include,~~includes, 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 three months ended ~~September 30, 2016,~~March 31, 2017, we issued and sold ~~622,846~~2,087,647 common units with a weighted average sales price of ~~$47.39~~$48.23 per unit under our equity distribution agreements for net cash proceeds of approximately ~~$28.7~~$99.4 million (net of approximately ~~$0.8~~$1.3 million in commissions and professional service expenses). During the ~~nine months ended September 30, 2016,~~period from April 1, 2017 to May 3, 2017, we issued and sold ~~6,703,984~~an additional 253,414 common units with a weighted average sales price of ~~$43.98~~$53.65 per unit under our equity distribution agreements for net cash proceeds of approximately ~~$290.5~~$13.5 million (net of approximately $4.4 million in commissions and professional service expenses). During the period from October 1, 2016 to November 2, 2016, we issued and sold an additional 628,914 common units with a weighted average sales price of $48.05 per unit under our equity distribution agreement for net cash proceeds of approximately $29.9 million (net of approximately $0.3$0.1 million in commissions and professional service expenses). We used the net cash proceeds for general partnership purposes as described above.

~~Private Placement~~Repurchase of Common Units Owned by TD

~~On April 28, 2016,~~Following an offer received from TD with respect to common units owned by TD not subject to the call option, we ~~issued~~repurchased 736,262 common units from TD at an aggregate price of ~~2,416,987~~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.

During the three months ended March 31, 2017, TEP also received contributions ~~of $5.3 million~~ from TD of $2.3 million, primarily to indemnify TEP for costs associated with Trailblazer's Pipeline Integrity Management Program, as discussed in Note 13 – Legal and Environmental Matters~~, and received~~. During the three months ended March 31, 2017, TEP recognized contributions from and distributions ~~from~~to noncontrolling interests of ~~$8.7~~$0.7 million and ~~$5.0~~$1.4 million, respectively, which primarily consisted of activity associated with TD's 2% noncontrolling interest in Pony Express.

11. 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.

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.

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 Terminals and NatGas prior to its acquisition on January 1, 2017 is allocated to predecessor operations in the table below. Historical earnings of transferred businesses for periods prior to the date of those common control 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 unitholders. We present the financial results of any transferred business prior to the 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 three ~~and nine~~ months ended ~~September 30, 2016~~March 31, 2017 and ~~2015:~~2016:

12. Regulatory Matters

There are ~~currently~~ no regulatory proceedings challenging the ~~currently effective~~ transportation rates of Pony Express, Rockies Express, Tallgrass Interstate Gas Transmission, LLC ("TIGT") or Trailblazer Pipeline Company LLC ("Trailblazer"). ~~On October 30, 2015, Tallgrass Interstate Gas Transmission, LLC ("TIGT") filed a general rate case~~We have certain regulatory filings currently pending with the FERC, pursuant to Section 4 of the Natural Gas Act ("NGA"), discussed in more detail below. 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.

~~TIGT~~

~~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 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 costs it incurred to maintain system safety, environmental compliance and reliability. 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, had 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 certain 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 "Suspension Order"). In the 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 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 22, 2016, a Settlement Judge was appointed in the case to assist the participants in exploring the possibility of settlement. On March 31, 2016, the FERC issued an order denying certain rehearing requests concerning the CRM, granting in part a motion to remove certain pro forma tariff records from the hearing, and also requested comments in order to assess the need for a technical conference. The FERC also retained for resolution through hearing the pro forma tariff records related to TIGT's proposed charge at delivery points lacking electronic flow measurement and removed from hearing the other issues related to the pro forma tariff records. Whether any issues will be resolved through technical conference is pending. The FERC also directed TIGT to provide additional information related to certain pro forma tariff records, which TIGT filed on April 14, 2016. On June 23, 2016, the FERC approved the implementation of TIGT's filed postage stamp rates, subject to refund, effective on May 1, 2016.

TIGT has reached an agreement in principle with customers representing a majority of firm fee revenue on the TIGT System for the year ended December 31, 2015 to settle all rate related issues set for hearing in its existing FERC rate case, including the issues of a cost recovery mechanism and a non-Electronic Flow Measurement charge. On May 5, 2016, the Acting Chief Administrative Law Judge issued an Order suspending the procedural schedule in the case as a result of the agreement in principle. On June 8, 2016, TIGT filed with the FERC its offer of settlement which resolves all issues in the case, with the exception of certain non-rate related tariff issues which remain subject to the FERC's review and approval. On June 9, 2016, the Presiding Administrative Law Judge issued an Order shortening the period for any comments on the settlement, such that comments were due by June 13, 2016. No adverse comments were filed. The offer of settlement was certified to the FERC by the Administrative Law Judge on July 14, 2016. The Judge found that the 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. The FERC issued an order on November 2, 2016 approving the settlement, finding that it appears to be fair and reasonable and in the public interest.

~~Trailblazer~~

13. 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, ~~had~~have recorded no reserve for legal claims as of ~~September 30, 2016~~March 31, 2017 or December 31, ~~2015.~~2016.

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, ~~in which Rockies Express seeks~~seeking approximately $303 million in damages and other relief. Specifically, Rockies Express has asserted that Ultra owes approximately $303 million for past transportation service charges and for reservation charge fees that Rockies Express would have received over the term of the service agreement had Ultra not defaulted, in addition to other amounts owed under law or equity.

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. On May 10, 2016, Ultra filed a notice of bankruptcy in the Harris County state court proceeding,~~Texas, which ~~asserted that pursuant to section 362(a) of the Bankruptcy Code, the filing of Ultra's Chapter 11 petition~~ operated as a stay of the Harris County state court proceeding. ~~Accordingly,~~

On January 12, 2017, Rockies Express ~~intends~~and Ultra entered into an agreement to ~~pursue its~~settle Rockies Express' approximately $303 million claim inagainst Ultra's bankruptcy estate. In accordance with the settlement agreement, Ultra has agreed to make a cash payment to Rockies Express of $150 million no later than July 12, 2017, and Ultra has entered 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 was part of Ultra's Chapter 11 ~~proceeding.~~reorganization plan, which was confirmed by the U.S. Bankruptcy Court on March 14, 2017. On April 12, 2017, Ultra announced that it successfully completed its restructuring in the U.S. Bankruptcy Court and emerged from Chapter 11 bankruptcy.

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 ~~seeks~~sought unspecified damages from Rockies Express and ~~asserts~~asserted claims of breach of contract, negligent misrepresentation, unjust enrichment and quantum meruit. Michels ~~has~~ also filed notices of Mechanic's Liens in Monroe and Noble Counties, asserting $24.2 million as the amount due. ~~The case is currently scheduled to go to trial in April 2017.~~

On February 2, 2017, Rockies Express ~~also previously filed Petition~~and Michels agreed to resolve Michels' claims for ~~Declaratory Judgment, Injunctive Relief and Damages against Michels in Johnson County, Kansas.

Subsequently, Rockies Express and ~~plans~~Michels entered into a definitive agreement with respect to ~~continue~~the settlement and Rockies Express made the $10 million cash payment to ~~vigorously contest all of the claims in this matter.~~Michels on February 16, 2017.

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 ~~$4.3~~$3.8 million and ~~$4.8~~$4.0 million at ~~September 30, 2016~~March 31, 2017 and December 31, ~~2015,~~2016, 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, Tallgrass Midstream, LLC ("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

~~In 2014 and 2015,~~ Trailblazer ~~conducted~~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 ~~and preliminary analysis on segments of its natural gas pipeline to evaluate the growth rate of corrosion downstream of compressor stations.~~in 2014, Trailblazer ~~currently believes that~~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 ~~maximum allowable operating pressure~~MAOP of 1,000 pounds per square ~~inch.~~inch across all segments of the Trailblazer Pipeline. Such repair or replacement will likely occur over a period of years, depending upon ~~final assessment of corrosion growth rates and~~ the remediation and repair plan implemented by Trailblazer. Segments of the Trailblazer ~~is currently operating at~~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 ~~than its current maximum allowable operating pressure, public notice of which was first provided in June 2014.~~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 ~~TEP.~~us.

~~During 2015,~~

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 based on preliminary analysis of the smart tool surveys performed in 2014. Segments of the Trailblazer Pipeline that require full replacement are currently expected to cost in the range of approximately $2.2 million to $2.7 million per mile. Repair costs on sections of the pipeline that do not require full replacement are expected to be less on a per mile basis. Trailblazer is continuing to develop a remediation and repair plan, which involves, among other things, finalizing cost recovery options, establishing project scope and timing and setting an overall project budget. Inmillion. During 2016, Trailblazer ~~intends to replace~~completed additional excavation digs and replaced approximately 8 miles of pipe ~~install additional ground beds,~~at an aggregate cost of approximately $19.0 million. In 2017, Trailblazer intends to complete final remediation and ~~continue remediating areas with external control anomalies~~cleanup of the pipe replacement at an estimated cost of ~~$21.5~~$2.5 million. Trailblazer is currently exploring all possible cost recovery ~~options.

In connection with ~~TEP's~~our acquisition of the Trailblazer Pipeline, TD agreed to contractually indemnify TEP for ~~any~~certain 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~~were necessitated by external corrosion caused by the pipeline's disbonded Hi-Melt CTE coating. The contractual indemnity provided ~~to TEP~~ by TD ~~is currently~~was capped at $20 million and iswas subject to ~~an annual~~a $1.5 million deductible. ~~During the nine months ended September 30, 2016,~~ TEP has received ~~contributions of $5.3~~$20 million from TD ~~related~~pursuant to the ~~indemnity.~~contractual indemnity as of March 31, 2017.

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, approximately 10,000 bbls of crude oil were released at the Sterling Terminal as the result of a defective roof drain system on a storage tank. The release was restricted to the containment area designed for such purpose and approximately 9,000 bbls were recovered. We currently expect that the total cost to remediate the release will be less than $600,000.

14. ~~Reporting~~Reportable Segments

Our operations are located in the United States. We are organized into three ~~reporting~~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. The Crude Oil Transportation & Logistics segment also includes our 100% membership interest in Terminals acquired effective January 1, 2017.

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 an integrated natural gas storage ~~facilities~~facility 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%~~100% membership interest in NatGas acquired effective January 1, 2017 and our 49.99% membership interest in Rockies Express, including the additional 24.99% membership interest acquired effective ~~May 6, 2016, as discussed in Note 3 –~~ March 31, 2017~~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 and the 2024 Notes, public company costs, and equity-based compensation expense.

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.

The following tables set forth our segment information for the periods indicated:

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.

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 collectsWe collect deficiency payments for ~~barrels~~volumes 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.

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 measures, for each of the periods indicated:

Three Months Ended ~~September 30, 2016~~March 31, 2017 Compared to the Three Months Ended ~~September 30, 2015~~March 31, 2016

Revenues. Total revenues were ~~$152.1~~$144.4 million for the three months ended ~~September 30, 2016,~~March 31, 2017, compared to ~~$138.2~~$147.2 million for the three months ended ~~September 30, 2015,~~March 31, 2016, which represents ~~an increase~~a decrease of ~~$14.0~~$2.8 million, or ~~10%~~2%, in total revenues. The overall ~~increase~~decrease in revenue was largely driven by ~~increased~~decreased revenues of ~~$12.6 million and $1.3~~$9.6 million in the Crude Oil Transportation & Logistics segment, partially offset by increased revenues of $3.8 million and $3.1 million in the Natural Gas Transportation & Logistics and Processing & Logistics segments, respectively, as discussed further below.

Operating costs and expenses. Operating costs and expenses were ~~$87.5~~$80.6 million for the three months ended ~~September 30, 2016~~March 31, 2017 compared to ~~$85.2~~$83.2 million for the three months ended ~~September 30, 2015,~~March 31, 2016, which represents ~~an increase~~a decrease of ~~$2.3~~$2.6 million, or 3%. The overall ~~increase~~decrease in operating costs and expenses ~~was primarily~~is driven by increased operating costs and expenses of $3.4 million, $1.5 million and $1.0 million in the Crude Oil Transportation & Logistics, Corporate and Other, and Processing & Logistics segments, respectively, partially offset by decreased operating costs and expenses of ~~$3.6~~$2.1 million, $0.8 million, and $0.3 million in the Natural Gas Transportation & Logistics, ~~segment,~~Processing & Logistics, and Crude Oil Transportation & Logistics segments, respectively, as discussed further ~~below.~~below, partially offset by a $0.6 million increase in corporate general and administrative costs primarily due to increased costs associated with equity-based compensation grants under the general partner's Long-term Incentive Plan as well as legal costs associated with transactions during the three months ended March 31, 2017.

Interest expense, net. Interest expense of ~~$10.9~~$14.7 million for the three months ended ~~September 30, 2016 and $3.9 million for the three months ended September 30, 2015~~March 31, 2017 was primarily composed of interest and fees associated with our revolving credit facility ~~as well as~~and the 2024 Notes issued on September 1, 2016. Interest expense of $7.5 million for the three months ended March 31, 2016 was primarily composed of interest and fees associated with our revolving credit facility. The increase in interest and fees associated with our revolving credit facility is primarily due to increased borrowings to fund a portion of our ~~December 2015~~2016 acquisition of ~~BNN Western, LLC ("Western") 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 and our recent acquisitions of Terminals and NatGas effective ~~May 6, 2016.~~January 1, 2017, 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~~gain (loss) on derivative instrument. Unrealized gain on derivative instrument of $1.9 million for the three months ended March 31, 2017 and unrealized loss on derivative instrument of ~~$4.4~~$8.9 million for the three months ended March 31, 2016 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. As of February 1, 2017, no common units remained subject to the call option.

Equity in earnings of unconsolidated ~~investment.~~investments. Equity in earnings of unconsolidated ~~investment of $12.1~~investments was $20.7 million and $0.7 million for the three months ended ~~September 30,~~March 31, 2017 and 2016, respectively. Equity in earnings of unconsolidated investments of $20.7 million for three months ended March 31, 2017 primarily reflects our portion of earnings and the amortization of a negative basis difference of $3.5 million associated with our ~~acquisition of a~~ 25% membership interest in Rockies Express ~~effective~~acquired in May ~~6, 2016.~~

~~Other income, net.~~ ~~Other income, net typically includes rental income and income earned from certain customers~~2016, as well as $0.7 million related to ~~the capital costs we incurred to connect these customers to~~ our ~~system. Other income was $0.5~~investment in Deeprock Development. Equity in earnings of unconsolidated investments of $0.7 million for the three months ended ~~September 30, 2016 and 2015.~~

~~Net income attributable to noncontrolling interests.~~ Net income attributable to noncontrolling interests of $1.1 million for the three months ended September 30, 2016 primarily reflects the net income allocated to TD's 2% noncontrolling interest in Pony Express. Net income attributable to noncontrolling interest of $6.9 million for the three months ended September 30, 2015 primarily reflects income allocated to TD's 33.3% noncontrolling interest of Pony Express.

~~Nine Months Ended September 30, 2016 Compared to the Nine Months Ended September 30, 2015~~

~~Revenues.~~ Total revenues were $444.5 million for the nine months ended September 30, 2016, compared to $385.8 million for the nine months ended September 30, 2015, which represents an increase of $58.6 million, or 15%, in total revenues. The overall increase in revenue was largely driven by increased revenues of $75.0 million in the Crude Oil Transportation & Logistics segment, partially offset by decreased revenues of $12.9 million and $3.3 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 $259.0 million for the nine months ended September 30, 2016 compared to $250.8 million for the nine months ended September 30, 2015, which represents an increase of $8.2 million, or 3%. The overall increase in operating costs and expenses is primarily driven by increased operating costs and expenses of $19.2 million in the Crude Oil Transportation & Logistics segment, partially offset by decreased operating costs and expenses of $7.3 million and $5.3 million in the Processing & Logistics and Natural Gas Transportation & Logistics segments, respectively, as discussed further below.

~~Interest expense, net.~~ Interest expense of $27.6 million for the nine months ended September 30, 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 $11.2 million for the nine months ended September 30, 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 associated with our revolving credit facility is primarily 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.

~~Unrealized gain on derivative instrument.~~ Unrealized gain on derivative instrument of $5.6 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 $35.4 million for the nine months ended September 30,~~March 31, 2016 reflects our portion of earnings ~~and the amortization of a negative basis difference of $5.6 million~~ associated with our acquisition of a 25% membership interest in Rockies Express effective May 6, 2016. The equity in earnings for the nine months ended September 30, 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 inDeeprock Development. For additional information, see Note 137 – ~~Legal and Environmental Matters.~~Investments in Unconsolidated Affiliates.

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 ~~nine~~three months ended ~~September 30, 2016~~March 31, 2017 was ~~$1.3~~$0.1 million compared to ~~$2.0~~$0.6 million for the ~~nine~~three months ended ~~September 30, 2015.~~March 31, 2016. The decrease in other income was driven by lower income related to reimbursable projects at TIGT due to contract modifications.

Net income attributable to noncontrolling interests. Net income attributable to noncontrolling interests of ~~$3.2~~$0.9 million for the ~~nine~~three months ended ~~September 30,~~March 31, 2017 compared to $1.0 million for the three months ended March 31, 2016 primarily reflects the net income allocated to TD's 2% noncontrolling interest in Pony Express. Net income attributable to noncontrolling interest of $5.9 million for the nine months ended September 30, 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 September 30, 2015.

~~Nine Months Ended September 30, 2016 Compared to the Nine Months Ended September 30, 2015~~

~~Revenues.~~ Natural Gas Transportation & Logistics segment revenues were $94.9 million for the nine months ended September 30, 2016, compared to $98.2 million for the nine months ended September 30, 2015, which represents a decrease of $3.3 million, or 3%, in segment revenues as a result of a $2.2 million decrease in sales of natural gas, NGLs, and crude oil as a result of lower volumes of natural gas sold and a 14% decrease in natural gas prices and a $1.1 million decrease in natural gas transportation services primarily driven by a change in the fuel recovery structure as discussed above and warmer weather conditions that created less demand for short-term transportation capacity during the nine months ended September 30, 2016 compared to the nine months ended September 30, 2015. These decreases were partially offset by increased tariff rates recognized at TIGT subsequent to the rate case settlement effective May 1, 2016.

~~Operating costs and expenses~~. Operating costs and expenses in the Natural Gas Transportation & Logistics segment were $59.9 million for the nine months ended September 30, 2016, compared to $65.2 million for the nine months ended September 30, 2015, which represents a decrease of $5.3 million, or 8%. The overall decrease in operating costs and expenses was primarily driven by a $4.7 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 $0.8 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, a $0.7 million decrease in general and administrative costs due to a reduction in allocated costs to the segment and a $0.2 million decrease in cost of sales due to decreased volumes of natural gas sold, partially offset by a reduction in our fuel tracker obligations at Trailblazer driven by the FERC approval of our annual fuel tracker filing during the nine months ended September 30, 2015. These decreases were partially offset by a $1.3 million increase in operations and maintenance due to increased pipeline integrity work during the nine months ended September 30, 2016.

The decrease in segment revenues was primarily due to a $10.5 million decrease in the sales of natural gas, NGLs, and crude oil driven by lower NGL sales of $9.4 million due to lower volumes processed and a 7% decrease in NGL prices and a $2.5 million decrease in processing and other revenues driven by lower processing fees at TMID due to decreased volumes processed, partially offset by a $2.3 million increase in revenue at Water Solutions 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 $70.9 million for the nine months ended September 30, 2016 compared to $78.3 million for the nine months ended September 30, 2015, which represents a decrease of ~~$7.3~~$0.8 million, or 9%4%. The decrease in operating costs and expenses was ~~driven~~primarily due to a $1.4 million gain on disposal of assets from insurance proceeds received during the three months ended March 31, 2017 related to assets destroyed by a 2016 fire caused by a lightning strike, as well as a $1.0 million decrease ~~of $7.5 million~~ in cost of sales ~~primarily due to decreased~~driven by lower producer settlements and NGL ~~prices and~~sales volumes processed as discussed above, a decrease of $2.6 million in loss on disposal of assets as a result of the $1.8 million loss on Western assets destroyed by fire as a result of a lightning strike during the nine months ended September 30, 2016, compared to a $4.5 million non-cash loss recognized on the sale of compressor assets at TMID in 2015 and a ~~$0.5~~$0.6 million decrease in ~~operations~~general and ~~maintenance costs due to less downtime for plant maintenance activities during the nine months ended September 30, 2016 compared to the nine months ended September 30, 2015.~~administrative expenses.

Liquidity and Capital Resources Overview

Our primary sources of liquidity for the three months ended ~~September 30, 2016~~March 31, 2017 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. For additional information regarding our revolving credit facility and senior unsecured notes, see Note 9 – Long-term Debt. For additional information regarding our equity transactions during the quarter, see Note 10 – Partnership Equity and Distributions.

Our total liquidity as of ~~September 30, 2016~~March 31, 2017 and December 31, ~~2015~~2016 was as follows:

Available capacity under the revolving credit facility	183,000			735,000
Total liquidity	$	184,198		$	736,873

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 September 30, 2016, we are in compliance with the covenants required under the revolving credit facility.

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 September 30, 2016, the weighted average interest rate on outstanding borrowings was 2.28%. During the nine months ended September 30, 2016, our weighted average effective interest rate, including the interest on outstanding borrowings, commitment fees, and amortization of deferred financing costs, was 2.72%.

~~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 offering to repay outstanding borrowings under its existing senior secured revolving credit facility.

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 September 30, 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.

During the three months ended September 30, 2016, we issued and sold 622,846 common units with a weighted average sales price of $47.39 per unit under our equity distribution agreements for net cash proceeds of approximately $28.7 million (net of approximately $0.8 million in commissions and professional service expenses). During the nine months ended September 30, 2016, we issued and sold 6,703,984 common units with a weighted average sales price of $43.98 per unit under our equity distribution agreements for net cash proceeds of approximately $290.5 million (net of approximately $4.4 million in commissions and professional service expenses). During the period from October 1, 2016 to November 2, 2016, we issued and sold an additional 628,914 common units with a weighted average sales price of $48.05 per unit under our equity distribution agreement for net cash proceeds of approximately $29.9 million (net of approximately $0.3 million 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~~barrels transported, the amount of deficiency payments received, and the volume of prior deficiencies utilized during the period.

As of ~~September 30, 2016,~~March 31, 2017, we had a working capital deficit of ~~$17.0~~$59.6 million compared to a working capital deficit of ~~$11.7~~$38.1 million at December 31, ~~2015,~~2016, which represents a decrease in working capital of ~~$5.3~~$21.5 million. The overall decrease in working capital was primarily attributable to changes in the following components:

an increase in deferred revenue of ~~$25.6~~$16.3 million primarily from deficiency payments collected by Pony Express;

a decrease in derivative assets at fair value of $10.7 million as we exercised the remainder of the call option granted by TD; and

an increase in accrued taxes of ~~$6.8~~$4.9 million ~~as a result of tax assessments; and~~

~~a decrease of $4.7 million in accounts receivable primarily~~ due to ~~a decrease in incremental barrels shipped~~higher estimated property taxes for 2017 at Pony ~~Express in September 2016 compared to December 2015.~~Express.

These working capital decreases were partially offset ~~by:~~

~~an increase of $25.7 million in derivative assets at fair value as a result of the reclassification of the call option derivative to current assets as of September 30, 2016; and~~

by a decrease in accrued liabilities of ~~$5.2~~$9.9 million primarily due to a decrease in ~~accounts payable, primarily driven by~~interest accrued at March 31, 2017 compared to December 31, 2016 due to an interest payment on the ~~timing of project invoices and payment of contractor retainages related to the construction of the Pony Express lateral~~2024 Notes in ~~Northeast Colorado.~~March 2017.

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.

~~Nine~~Three Months Ended ~~September 30, 2016~~March 31, 2017 Compared to the ~~Nine~~Three Months Ended ~~September 30, 2015~~March 31, 2016

Operating Activities. Cash flows provided by operating activities were ~~$305.9~~$104.2 million and ~~$197.5~~$93.2 million for the ~~nine~~three months ended ~~September 30,~~March 31, 2017 and 2016, ~~and 2015,~~ respectively. The increase in net cash flows provided by operating activities of ~~$108.4~~$11.1 million was primarily driven by the increase in operating results as discussed above, $20.7 million of distributions from unconsolidated investments received primarily from Rockies Express, and a net increase in cash inflows from changes in working capital, primarily driven by a $19.5 million increase in net cash inflows from accounts receivable due to collection of receivables during the nine months ended September 30, 2016 associated primarily with an increase of incremental barrels shipped at Pony Express, and a $11.3$9.0 million increase in deferred revenue associated ~~primarily~~ with deficiency payments ~~received~~collected by Pony ~~Express.~~Express during the three months ended March 31, 2017.

Investing Activities. Cash flows used in investing activities were ~~$549.6 million and $769.8~~$562.0 million for the ~~nine~~three months ended ~~September 30, 2016 and 2015, respectively. During~~March 31, 2017. Investing cash outflows for the ~~nine~~three months ended ~~September 30, 2016, net cash used in investing activities~~March 31, 2017 were primarily driven by by:

cash outflows of ~~$436.0~~$400.0 million for the acquisition of ~~a 25%~~an additional 24.99% membership interest in Rockies Express on ~~May 6,~~March 31, 2017;

cash outflows of $140.0 million for the acquisition of Terminals and NatGas on January 1, 2017; and

capital expenditures of $26.8 million, primarily due to spending on an additional freshwater connection at Water Solutions and remediation digs on the Pony Express System as discussed in Note 13 – Legal and Environmental Matters.

These cash outflows were partially offset by $10.1 million of distributions from Rockies Express in excess of cumulative earnings recognized.

Cash flows used in investing activities were $70.4 million for the three months ended March 31, 2016. Investing cash outflows for the three months ended March 31, 2016 were primarily driven by:

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,~~ below; and

capital expenditures of ~~$45.3~~$21.2 million, primarily due to post in-service spending on Pony Express System projects, and contributions to Rockies Express in the amount of $35.5 million. During the nine months ended September 30, 2015, net cash used in investing activities were driven by the $700.0 million cash outflow 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 capital expenditures of $65.1 million, primarily due to construction of the Pony Express System, including the lateral in Northeast Colorado.projects.

Financing Activities. Cash flows provided by financing activities were ~~$242.5 million and $590.1~~$457.1 million for the ~~nine~~three months ended ~~September 30, 2016 and 2015, respectively.~~March 31, 2017. Financing cash inflows for the ~~nine~~three months ended ~~September 30, 2016~~March 31, 2017 were primarily driven by:

~~proceeds from the issuance of $400 million in aggregate principal amount of 5.50% Senior Notes due 2024;~~

~~the issuance of 6,703,984 common units under the Equity Distribution Agreements for net cash proceeds of $290.5 million;~~

net borrowings under the revolving credit facility of ~~$252.0~~$552.0 million; and

the issuance of ~~2,416,987~~2,087,647 common units ~~representing limited partnership interests in a private placement transaction~~under our Equity Distribution Agreements for net cash proceeds of ~~$90.0 million; and~~

~~contributions from noncontrolling interests of $8.7 million, which primarily consisted of contributions from TD to Pony Express.~~$99.4 million.

These financing cash inflows were partially offset by cash outflows of:

$~~425.9~~72.4 million for the exercise of the remainder of the call option granted by TD covering 1,703,094 common units; and

$35.3 million for the 736,262 common units repurchased from TD.

Cash flows used in financing activities were $21.5 million for the three months ended March 31, 2016. Financing cash outflows for the three months ended March 31, 2016 were primarily driven 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; and

distributions to unitholders of ~~$207.5 million; and~~$59.0 million.

~~$151.4 million for the partial exercise of the call option granted~~

These financing cash outflows were partially offset by ~~TD covering 3,563,146 common units.~~

~~Cash flows provided by financing activities for the nine months ended September 30, 2015 were primarily driven by:~~

~~net~~ cash ~~proceeds of $551.2 million from the issuance of 11,200,000 common units in a public offering;~~inflows from:

net borrowings under the revolving credit facility of ~~$137.0~~$447.0 million; and

~~contributions from noncontrolling interests~~the issuance of ~~$19.3 million, primarily driven by contributions from TD to Pony Express.~~

~~These financing~~337,311 common units under the Equity Distribution Agreement for net cash ~~inflows were partially offset by distributions to unitholders~~proceeds of ~~$113.3~~$12.6 million.

Distributions

We do not have a legal obligation to pay distributions except as provided in our partnership agreement. A distribution of ~~$0.795~~$0.835 per unit, or ~~$85.3~~$91.4 million in the aggregate, for the three months ended ~~September 30, 2016~~March 31, 2017 was announced on ~~October 5, 2016~~April 17, 2017 and will be paid on ~~November 14, 2016~~May 15, 2017 to unitholders of record on ~~October 31, 2016.~~April 28, 2017. As of ~~November 2, 2016,~~May 3, 2017, we had a total of ~~72,949,796~~73,272,277 common and general partner units outstanding, which equates to an aggregate minimum quarterly distribution of approximately ~~$21.0~~$21.1 million per quarter and approximately ~~$83.9~~$84.3 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 towe expect will 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 ~~$46~~$91 million for capital expenditures in ~~2016,~~2017, of which approximately ~~$34~~$75 million is expected for expansion projects and approximately ~~$12~~$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:


	Nine Months Ended September 30,				Three Months Ended March 31,
	2016		2015		2017		2016
	(in thousands)				(in thousands)
Maintenance capital expenditures	$	7,085	$	9,237	$	63	$	2,168
Expansion capital expenditures	19,308		17,453		22,420		8,392
Total capital expenditures incurred	$	26,393	$	26,690	$	22,483	$	10,560

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 ~~$7.1~~$0.1 million for the ~~nine~~three months ended ~~September 30, 2016~~March 31, 2017 from ~~$9.2~~$2.2 million for the ~~nine~~three months ended ~~September 30, 2015~~March 31, 2016 is primarily driven by ~~decreased maintenance capital expenditures~~contributions from TD to TEP in order to indemnify TEP for certain out of pocket costs related to repairing or remediating the ~~Processing & Logistics~~Trailblazer Pipeline, as discussed further in Note 13 – Legal and ~~the Natural Gas Transportation & Logistics segments.~~Environmental Matters. 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 ~~$19.3~~$22.4 million for the ~~nine~~three months ended ~~September 30, 2016 from $17.5 million for the nine months ended September 30, 2015~~March 31, 2017 is primarily driven by increased expansion capital expenditures in the Processing and Logistics and Crude Oil Transportation & Logistics segments. Expansion capital expenditures for the three months ended March 31, 2017 consisted primarily of spending on an additional freshwater connection at Water Solutions and remediation digs on the Pony Express System, ~~lateral~~as discussed in ~~Northeast Colorado prior to commencement of commercial operations in the second quarter of 2015.~~Note 13 – Legal and Environmental Matters. Expansion capital expenditures of ~~$19.3~~$8.4 million for the ~~nine~~three months ended ~~September 30,~~March 31, 2016 consisted primarily of post in-service spending on Pony Express System projects and costs associated with construction of the Sterling Terminal.

In addition, we invested cash in unconsolidated affiliates of $6.7 million and $0.1 million during the three months ended March 31, 2017 and 2016, respectively, to fund our share of capital projects.

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.

Contractual Obligations

There have been no material changes in our contractual obligations as reported in our ~~2015~~2016 Form 10-K.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Critical Accounting Policies and Estimates

The critical accounting policies and estimates used in the preparation of our condensed consolidated financial statements are set forth in our ~~2015~~2016 Form 10-K for the year ended December 31, ~~2015~~2016 and have not changed. Our disclosure of critical accounting policies and estimates with respect to goodwill is repeated below for the purpose of providing additional information regarding the impairment testing performed as of December 31, 2015.



~~Description~~	~~Judgments and Uncertainties~~	~~Effect if Actual Results Differ from Assumptions~~
~~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.	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.	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 2015 using the methodology described herein, and determined there was no impairment. As a result of a decreased commodity prices in late 2015 and into early 2016, which caused a significant drop in the volumes anticipated from several producers from which TMID receives natural gas for processing, we identified a potential impairment trigger with respect to the $79.2 million of goodwill at the TMID reporting unit, which is a component of our Processing & Logistics segment. We tested TMID's goodwill for impairment as of December 31, 2015 and determined that the fair value of the reporting unit exceeds the carrying value by approximately 21%. As a result, no impairment charge was recorded, however our analysis includes assumptions of a gradual recovery of commodity prices and a corresponding increase in volumes over time. If our outlook for long-term commodity prices is not realized, or our producers further decrease volumes, we could have an impairment in the future. While commodity prices do not have a significant direct exposure to the cash flows projected at TMID, the current commodity price environment has had an indirect impact on TMID's business as certain producers have significantly reduced their anticipated volumes. Keeping all other assumptions constant, as of December 31, 2015 an increase in the discount rate applied of approximately 1.38% or a decrease in overall cash flows by more than 16% would result in a step one failure, however we do not believe that these represent reasonably likely assumptions. If the reporting unit fails step one in the future, we would be required to perform step two of the goodwill impairment test and up to $79.2 million of goodwill at the TMID reporting unit could be written off in the period that the impairment is triggered. During the third quarter of 2016, we completed our annual goodwill impairment testing for all reporting units, and determined that there was no impairment.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Commodity Price Risk

As of ~~September 30, 2016~~March 31, 2017 approximately ~~91%~~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 9%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~~Starting in the ~~foreseeable future. Starting in~~second half of 2014, the prices of crude oil, natural gas, and NGLs ~~were~~became extremely volatile and declined significantly. Downward pressure and volatility onof commodity prices continued in 2015 ~~and the first half of~~before recovering somewhat in 2016 and ~~may continue for the foreseeable future.~~2017. 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 3%5% and 4% of our Adjusted EBITDA for ~~both~~ the three ~~and nine~~ months ended ~~September 30, 2016.~~

~~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 the third quarter of~~March 31, 2017 and 2016, we entered into a derivative contract for the sale of 30,000 barrels of crude oil, which settled in October 2016. The fair value of this swap was a liability of approximately $7,000 at September 30, 2016.respectively.

Historically, we have ~~also~~ 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. WeAccordingly, we have historically entered into derivative contracts with third parties for a substantial majority of the natural gas we ~~expect~~expected to collect ~~during the current year~~ for the purpose of hedging our commodity price exposures. ~~As of September 30,~~In 2016, we ~~had short~~also entered into long natural gas swaps ~~outstanding with a notional volume of approximately 0.8 Bcf, representing~~covering a portion of the natural gas that ~~is expected~~TMID expects to ~~be sold by~~purchase in 2017.

During 2016, we began entering into derivative contracts for the ~~first quarter~~sale of ~~2017. The fair value of these swaps was a liability of approximately $0.2 million at September 30, 2016.~~crude oil inventory.

We measure the risk of price changes in our crude oil and 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. ~~A hypothetical 10% increase in the crude oil price forward curve would result in a decrease of approximately $0.1 million in the net fair value of~~

The following table summarizes our crude oil derivative instruments as of September 30, 2016. A hypothetical 10% increase in the natural gas price forward curve would result in a decrease of approximately $0.2 million in the fair value of our natural gas derivative instruments as of September 30, 2016 as a result of our hedging program. For the purpose of determiningcommodity derivatives and the change in fair value ~~associated with the hypothetical natural gas~~that would be expected from a 10% price increase ~~scenario, we have assumed~~or decrease as of March 31, 2017, assuming a parallel shift in the forward curve through the end of ~~2016.~~2017:

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 ~~are intended to implement~~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 continue to qualify for an exemption to the clearing and exchange-execution requirements, we will still be subject to record keeping and reporting requirements. Other changes to the Commodity Exchange Act made as a result of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the CFTC's implementing regulations could significantly increase the cost of entering into new swaps.

Interest Rate Risk

~~As described in "Liquidity and Capital Resources Overview" above, on~~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~~$1.57 billion as of ~~September 30, 2016.~~March 31, 2017. 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. For loans bearing interest based on the base rate, the applicable margin was initially 1.00%, and for loans bearing interest based on the reserve adjusted Eurodollar rate, the applicable margin was initially 2.00%. After June 25, 2014, theThe 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~~$0.8 million based on our debt obligations as of ~~September 30, 2016.~~March 31, 2017.

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. ~~We have historically experienced only minimal credit losses in connection with our receivables.~~

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 50%~~a majority of our revenues derived from customers who have ~~an investment grade~~BB+ or Ba1 and better credit ~~rating~~ratings or are part of corporate families with ~~investment grade~~such credit ratings as of September 30, 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 current commodity price environment.March 31, 2017.

We also have indirect credit risk exposure with respect to our investment in Rockies Express. See Item 1A.—Risk Factors in our 2016 Form 10-K for additional information.

Item 4. Controls and Procedures
