CRESTWOOD MIDSTREAM PARTNERS LP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Note 1 – Organization and Business Description

Organization

The accompanying notes to the consolidated financial statements apply to Crestwood Equity Partners LP and Crestwood Midstream Partners LP, unless otherwise indicated. References in this report to “we,” “us,” “our,” “ours,” “our company,” the “partnership,” the “Company,” “Crestwood Equity,” “CEQP,” and similar terms refer to either Crestwood Equity Partners LP itself or Crestwood Equity Partners LP and its consolidated subsidiaries, as the context requires. Unless otherwise indicated, references to “Crestwood Midstream” and “CMLP” refer to Crestwood Midstream Partners LP and its consolidated subsidiaries.

The accompanying consolidated financial statements and related notes should be read in conjunction with our 2018 Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC) on February 22, 2019. The financial information as of March 31, 2019, and for the three months endedMarch 31, 2019 and 2018, is unaudited. The consolidated balance sheets as of December 31, 2018, were derived from the audited balance sheets filed in our 2018 Annual Report on Form 10-K.

Business Description

Crestwood Equity is a publicly-traded (NYSE: CEQP) Delaware limited partnership that develops, acquires, owns or controls, and operates primarily fee-based assets and operations within the energy midstream sector. We provide broad-ranging infrastructure solutions across the value chain to service premier liquids-rich natural gas and crude oil shale plays across the United States. We own and operate a diversified portfolio of crude oil and natural gas gathering, processing, storage and transportation assets that connect fundamental energy supply with energy demand across North America. Crestwood Equity is a holding company and all of its consolidated operating assets are owned by or through its wholly-owned subsidiary, Crestwood Midstream, a Delaware limited partnership.

Note 2 – Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

Our consolidated financial statements are prepared in accordance with Generally Accepted Accounting Principles (GAAP) and include the accounts of all consolidated subsidiaries after the elimination of all intercompany accounts and transactions. In management’s opinion, all necessary adjustments to fairly present our results of operations, financial position and cash flows for the periods presented have been made and all such adjustments are of a normal and recurring nature. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with GAAP have been omitted pursuant to the rules and regulations of the SEC.

Significant Accounting Policies

Effective January 1, 2019, we adopted the following accounting standard. There were no other material changes in our significant accounting policies from those described in our 2018 Annual Report on Form10-K.

Leases

We maintain leases in the ordinary course of our business activities. Our leases include those for the office buildings, crude oil railroad cars, certain vehicles and other operating facilities and equipment leases. We also sublease certain of our crude oil railroad cars and trucks to a third party. We do not have any material leases where we are considered to be the lessor. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Prior to January 1, 2019, we classified our leases as either capital or operating leases under Accounting Standards Codification (ASC) Topic 840, Leases (Topic 840). We recognized assets (included in property, plant and equipment) and liabilities (included in accrued expenses and other liabilities and other long-term liabilities) related to our capital leases on our

14

consolidated balance sheets. We also recognized depreciation expense and interest expense related to our capital leases on our consolidated statements of operations. The majority of our lease arrangements were classified as operating leases, under which we did not recognize assets or liabilities on our consolidated balance sheets, but rather recognized lease payments on our consolidated statements of operations as either costs of product/services sold or operations and maintenance expense on a straight-line basis over the lease term.

On January 1, 2019, we adopted the provisions of ASC Topic 842, Leases (Topic 842), which revises the accounting for leases by requiring certain leases to be recognized as assets and liabilities on the balance sheet, and requiring companies to disclose additional information about their leasing arrangements. We adopted the standard using the modified retrospective method. Based on the practical expedients allowed for in the standard, we did not reassess the current GAAP classification of leases, easements and rights of way that existed as of January 1, 2019, and we did not utilize the hindsight method in determining the assets and liabilities to be recorded for our existing leases on January 1, 2019. The adoption of this standard required us to make significant judgments on whether our revenue and expenditure-related contracts were considered to be leases (or contain leases) under Topic 842, and if contracts were considered to be leases whether they should be considered operating leases or finance leases under the new standard. We do not have any material revenue contracts that are considered leases under Topic 842.

Upon the adoption of this standard, on January 1, 2019, we recorded a $67.5 million increase to our operating lease right-of-use assets, a $18.6 million increase to our accrued expenses and other liabilities and a $48.9 million increase to our long-term operating lease liabilities, related to reflecting our operating leases on our consolidated balance sheet as a result of adopting the new standard. We also recorded a $1.6 million increase to our property, plant and equipment, $0.3 million increase to our accrued expenses and other liabilities and a $1.3 million increase to our other long-term liabilities, related to our finance leases (which were all formerly capital leases under Topic 840) as a result of applying the provisions of the new standard to the leases. The adoption of the standard did not result in a material cumulative effect of accounting change to our consolidated financial statements. The following table summarizes the balance sheet information related to our operating and finance leases at March 31, 2019 (in millions):

Operating Leases
Operating lease right-of-use assets, net	$	61.6
Accrued expenses and other liabilities	$	18.1
Long-term operating lease liabilities	48.2
Total operating lease liabilities	$	66.3
Finance Leases
Property, plant and equipment	$	14.1
Less: accumulated depreciation	2.7
Property, plant and equipment, net	$	11.4
Accrued expenses and other liabilities	$	2.9
Other long-term liabilities	7.1
Total finance lease liabilities	$	10.0

The estimation of our right-of-use assets and lease liabilities requires us to make significant assumptions and judgments about the term of the lease, variable payments, and discount rates. Our operating leases have remaining terms that vary from one year to 14 years and certain of those leases have renewal options to extend the leases from one year to five years, or terminate the leases at our sole discretion. In addition, our finance leases have remaining terms that vary from two years to four years and certain of those leases have options to purchase the lease property by the end of the lease term. We made significant assumptions on the likelihood on whether we would renew our leases or purchase the property at the end of the lease terms in determining the discounted cash flows to measure our right-of-use assets and lease liabilities. The estimation of variable lease payments in determining discounted cash flows, including those with usage-based costs, also required us to make significant assumptions on the timing and nature of the variability of those payments based on the lease terms. We utilized discount rates ranging from 4.9% to 8.3% to estimate the discounted cash flows used in estimating our right-of-use assets and lease liabilities as of March 31, 2019, which were primarily based on our credit-adjusted collateralized incremental borrowing rate.

We recognize operating lease expense and amortize our right-of-use assets for our finance leases on a straight-line basis over the term of the respective leases. We have applied the practical expedient of not separating the lease and non-lease components

15

for our leases where the predominant consideration paid related to the underlying operating and finance lease contracts relate to the lease component.

New Accounting Pronouncement Issued But Not Yet Adopted

As of March 31, 2019, the following accounting standard had not yet been adopted by us:

In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326), which provides new guidance on how companies should evaluate their accounts and notes receivable and other financial instruments for impairment. The standard requires companies to evaluate their financial instruments for impairment by recording an allowance for doubtful accounts and/or bad debt expense based on certain categories of instruments rather than a specific identification approach. We expect to adopt the provisions of this standard effective January 1, 2020 and are currently evaluating the impact that this standard may have on our consolidated financial statements.

(2) Includes our Tres Holdings and PRBIC equity investments. We amortize the excess basis in these equity investments as an increase in our earnings from unconsolidated affiliates. We recorded amortization of the excess basis in our Tres Holdings and PRBIC equity investments of $0.3 million and $0.1 million, respectively, for the three months endedMarch 31, 2019, and $0.3 million and $0.2 million, respectively, for the three months endedMarch 31, 2018.

Distributions and Contributions

The following table summarizes our distributions and contributions from our unconsolidated affiliates (in millions):

	Distributions(1)				Contributions

(1) In April 2019, we received cash distributions from Stagecoach Gas, Crestwood Permian and Tres Holdings of approximately $12.4 million, $0.6 million and $1.2 million, respectively.

Other

Contingent Consideration. Pursuant to the Stagecoach Gas limited liability company agreement, we may be required to make payments of up to $57 million to Con Edison Gas Pipeline and Storage Northeast, LLC after December 31, 2020 if certain criteria are not met by Stagecoach Gas by December 31, 2020, including achieving certain performance targets on growth capital projects. These growth capital projects depend on the construction of other third-party expansion projects, and during 2017, those third-party projects experienced regulatory and other delays that caused Stagecoach Gas to delay its growth capital projects. As a result, our consolidated balance sheets reflect an other long-term liability of $57 million at March 31, 2019 and December 31, 2018.

Guarantee. CEQP issued a guarantee under which CEQP has agreed to fund 100% of the costs to build the Nautilus gathering system (which is currently estimated to cost $180 million, of which approximately $155.7 million has been spent through March 31, 2019) if Crestwood Permian fails to do so. The Nautilus gathering system is owned by Crestwood Permian Basin LLC, a 50% equity investment of Crestwood Permian. We do not believe this guarantee is probable of resulting in future losses based on our assessment of the nature of the guarantee, the financial condition of the guaranteed party and the period of time that the guarantee has been outstanding, and as a result, we have not recorded a liability on our consolidated balance sheets at March 31, 2019 and December 31, 2018.

Jackalope Acquisition. On April 9, 2019, Crestwood Niobrara LLC (Crestwood Niobrara), our consolidated subsidiary, acquired Williams Partners LP’s (Williams) 50% equity interest in Jackalope for approximately $484.6 million, which was funded through a combination of borrowings under the CMLP credit facility and the issuance of $235 million of new preferred units to CN Jackalope Holdings LLC (Jackalope Holdings) as further discussed in Note 9. The acquisition of this equity interest results in Crestwood Niobrara owning 100% of the equity interests in Jackalope. Crestwood Midstream Operating, LLC (Crestwood Midstream Operating), our consolidated subsidiary, will provide field operations and construction management services for Jackalope.

Note 5 – Risk Management

We are exposed to certain market risks related to our ongoing business operations. These risks include exposure to changing commodity prices. We utilize derivative instruments to manage our exposure to fluctuations in commodity prices, which is discussed below. Additional information related to our derivatives is discussed in Note 6.

19

Commodity Derivative Instruments and Price Risk Management

Risk Management Activities

We sell NGLs and crude oil to energy related businesses and may use a variety of financial and other instruments including forward contracts involving physical delivery of NGLs, heating oil and crude oil. We periodically enter into offsetting positions to economically hedge against the exposure our customer contracts create. Certain of these contracts and positions are derivative instruments. We do not designate any of our commodity-based derivatives as hedging instruments for accounting purposes. Our commodity-based derivatives are reflected at fair value in the consolidated balance sheets, and changes in the fair value of these derivatives that impact the consolidated statements of operations are reflected in costs of product/services sold. Our commodity-based derivatives that are settled with physical commodities are reflected as an increase to product revenues, and the commodity inventory that is utilized to satisfy those physical obligations is reflected as an increase to costs of product sold in our consolidated statements of operations. The following table summarizes the impact to our consolidated statements of operations related to our commodity-based derivatives reflected in operating revenues and costs of product/services sold during the three months endedMarch 31, 2019 and 2018 (in millions):

	Three Months Ended
	March 31,
	2019			2018
Product revenues	$	104.1		$	97.8
Gain (loss) reflected in costs of product/services sold	(2.9		)	7.8

We attempt to balance our contractual portfolio in terms of notional amounts and timing of performance and delivery obligations. This balance in the contractual portfolio significantly reduces the volatility in costs of product/services sold related to these instruments.

Commodity Price and Credit Risk

Notional Amounts and Terms

The notional amounts and terms of our derivative financial instruments include the following:

	March 31, 2019		December 31, 2018
	Fixed Price Payor	Fixed Price Receiver	Fixed Price Payor	Fixed Price Receiver
Propane, crude and heating oil (MMBbls)	28.8	29.5	27.8	30.1
Natural gas (Bcf)	1.6	1.6	1.8	1.8

Notional amounts reflect the volume of transactions, but do not represent the amounts exchanged by the parties to the financial instruments. Accordingly, notional amounts do not reflect our monetary exposure to market or credit risks. All contracts subject to price risk had a maturity of 36 months or less; however, 82% of the contracted volumes will be delivered or settled within 12 months.

Credit Risk

Inherent in our contractual portfolio are certain credit risks. Credit risk is the risk of loss from nonperformance by suppliers, customers or financial counterparties to a contract. We take an active role in managing credit risk and have established control procedures, which are reviewed on an ongoing basis. We attempt to minimize credit risk exposure through credit policies and periodic monitoring procedures as well as through customer deposits, letters of credit and entering into netting agreements that allow for offsetting counterparty receivable and payable balances for certain financial transactions, as deemed appropriate. The counterparties associated with our price risk management activities are energy marketers and propane retailers, resellers and dealers.

Certain of our derivative instruments have credit limits that require us to post collateral. The amount of collateral required to be posted is a function of the net liability position of the derivative as well as our established credit limit with the respective counterparty. If our credit rating were to change, the counterparties could require us to post additional collateral. The amount of additional collateral that would be required to be posted would vary depending on the extent of change in our credit rating as well as the requirements of the individual counterparty. In addition, we have margin requirements with a New York Mercantile

20

Exchange (NYMEX) broker related to our net asset or liability position with such broker. All collateral amounts have been netted against the asset or liability with the respective counterparty and are reflected in our consolidated balance sheets as assets and liabilities from price risk management activities.

The following table represents the fair value of our commodity derivative instruments with credit-risk related contingent features and their associated collateral (in millions):

	March 31, 2019		December 31, 2018
Aggregate fair value of derivative instruments with credit-risk-related contingent features(1)	$	2.6	$	2.2
NYMEX-related net derivative asset (liability) position	$	1.4	$	(9.4	)
NYMEX-related cash collateral posted	$	9.1	$	21.7
Cash collateral received	$	5.4	$	14.2

(1) At March 31, 2019 and December 31, 2018, we posted less than $0.1 million of collateral associated with these derivatives.

Note 6 – Fair Value Measurements

The accounting standard for fair value measurement establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The three levels of the fair value hierarchy are as follows:

• Level 1—Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 1 primarily consists of financial instruments such as exchange-traded derivatives, listed equities and US government treasury securities.

• Level 2—Pricing inputs are other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors, and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace throughout the full term of the instrument, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace. Instruments in this category include non-exchange-traded derivatives such as over the counter (OTC) forwards, options and physical exchanges.

• Level 3—Pricing inputs include significant inputs that are generally less observable from objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value.

Cash, Accounts Receivable and Accounts Payable

As of March 31, 2019 and December 31, 2018, the carrying amounts of cash, accounts receivable and accounts payable approximate fair value based on the short-term nature of these instruments.

Credit Facility

The fair value of the amounts outstanding under our CMLP credit facility approximates the carrying amounts as of March 31, 2019 and December 31, 2018, due primarily to the variable nature of the interest rate of the instrument, which is considered a Level 2 fair value measurement.

21

Senior Notes

We estimate the fair value of our senior notes primarily based on quoted market prices for the same or similar issuances (representing a Level 2 fair value measurement). The following table reflects the carrying amount (reduced for deferred financing costs associated with the respective notes) and fair value of our senior notes (in millions):

	March 31, 2019				December 31, 2018
	Carrying  Amount		Fair Value		Carrying  Amount		Fair Value
2023 Senior Notes	$	694.0	$	720.8	$	693.6	$	668.1
2025 Senior Notes	$	493.6	$	514.8	$	493.4	$	466.2

Financial Assets and Liabilities

As of March 31, 2019 and December 31, 2018, we held certain assets and liabilities that are required to be measured at fair value on a recurring basis, which include our derivative instruments related to heating oil, crude oil, and NGLs. Our derivative instruments consist of forwards, swaps, futures, physical exchanges and options.

Our derivative instruments that are traded on the NYMEX have been categorized as Level 1.

Our derivative instruments also include OTC contracts, which are not traded on a public exchange. The fair values of these derivative instruments are determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets. These instruments have been categorized as Level 2.

Our OTC options are valued based on the Black Scholes option pricing model that considers time value and volatility of the underlying commodity. The inputs utilized in the model are based on publicly available information as well as broker quotes. These options have been categorized as Level 2.

Our financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels.

The following tables set forth by level within the fair value hierarchy, our financial instruments that were accounted for at fair value on a recurring basis at March 31, 2019 and December 31, 2018 (in millions):

At March 31, 2019 and December 31, 2018, Crestwood Midstream’s outstanding standby letters of credit were $73.0 million and $68.0 million. Borrowings under the credit facility accrue interest at prime or Eurodollar based rates plus applicable spreads, which resulted in interest rates between 4.74% and 6.75% at March 31, 2019 and 4.63% and 6.75% at December 31, 2018. The weighted-average interest rate as of March 31, 2019 and December 31, 2018 was 4.79% in both periods.

Crestwood Midstream is required under its credit agreement to maintain a net debt to consolidated EBITDA ratio (as defined in its credit agreement) of not more than 5.50 to 1.0, a consolidated EBITDA to consolidated interest expense ratio (as defined in its credit agreement) of not less than 2.50 to 1.0, and a senior secured leverage ratio (as defined in its credit agreement) of not more than 3.75 to 1.0. At March 31, 2019, the net debt to consolidated EBITDA ratio was approximately 4.11 to 1.0, the consolidated EBITDA to consolidated interest expense ratio was approximately 4.41 to 1.0, and the senior secured leverage ratio was 1.36 to 1.0.

In April 2019, Crestwood Niobrara acquired the remaining 50% equity interest in Jackalope and funded approximately $250 million of the total purchase price through borrowings under Crestwood Midstream’s credit facility. Contemporaneously with the closing of the remaining interest in Jackalope, Crestwood Midstream entered into the First Amendment to the Second Amended and Restated Credit Agreement to modify certain defined terms and calculations, among other things, to account for the Jackalope acquisition. The other debt covenants under the amended credit agreement are materially consistent with the credit facility that existed at March 31, 2019.

Senior Notes

In April 2019, Crestwood Midstream issued $600 million of 5.625% unsecured senior notes due 2027 (the 2027 Senior Notes). The 2027 Senior Notes will mature on May 1, 2027, and interest is payable semiannually in arrears on May 1 and November 1 of each year, beginning November 1, 2019. The net proceeds from this offering of approximately $591.1 million were used to repay a portion of the outstanding borrowings under our credit facility, which included the borrowings that were used to fund the acquisition of the remaining 50% equity interest in Jackalope.

Note 8 - Earnings Per Limited Partner Unit

Our net income (loss) attributable to Crestwood Equity Partners is allocated to the subordinated and limited partner unitholders based on their ownership percentage after giving effect to net income attributable to the preferred units. We calculate basic net income per limited partner unit using the two-class method. Diluted net income per limited partner unit is computed using the treasury stock method, which considers the impact to net income attributable to Crestwood Equity Partners and limited partner units from the potential issuance of limited partner units.

We exclude potentially dilutive securities from the determination of diluted earnings per unit (as well as their related income statement impacts) when their impact on net income attributable to Crestwood Equity Partners per limited partner unit is anti-dilutive. The following table summarizes information regarding the weighted-average of common units excluded during the three months endedMarch 31, 2019 and 2018:

	Three Months Ended
	March 31,
	2019	2018
Preferred units (1)	7,125,744	7,125,744
Crestwood Niobrara’s preferred units(1)	5,775,394	7,055,735
Stock-based compensation performance units(2)	460,091	—
Subordinated units(2)	438,789	—

(1) See Note 9 for additional information regarding the potential conversion/redemption of our preferred units and Crestwood Niobrara’s preferred units to common units.

(2) For a description of our performance units and subordinated units, see our 2018 Annual Report on Form 10-K.

Note 9 – Partners’ Capital

Preferred Units

Subject to certain conditions, the holders of the preferred units have the right to convert their preferred units into (i) common units on a 1-for-10 basis or (ii) a number of common units determined pursuant to a conversion ratio set forth in Crestwood Equity’s partnership agreement upon the occurrence of certain events, such as a change in control. The preferred units have voting rights that are identical to the voting rights of the common units and will vote with the common units as a single class, with each preferred unit entitled to one vote for each common unit into which such preferred unit is convertible, except that the preferred units are entitled to vote as a separate class on any matter on which all unitholders are entitled to vote that adversely affects the rights, powers, privileges or preferences of the preferred units in relation to Crestwood Equity’s other securities outstanding.

Common Units

We have an employee unit purchase plan under which employees of the general partner may purchase our common units through payroll deductions up to a maximum of 10% of the employees’ eligible compensation, not to exceed $25,000 for any calendar year. During the three months endedMarch 31, 2019, there were 789 common units purchased under the plan. For a further description of our employee unit purchase plan, see our 2018 Annual Report on Form 10-K.

Distributions

Crestwood Equity

Limited Partners. A summary of CEQP’s limited partner quarterly cash distributions for the three months endedMarch 31, 2019 and 2018 is presented below:

Record Date	Payment Date	Per Unit Rate		Cash Distributions (in millions)
2019
February 7, 2019	February 14, 2019	$	0.60	$	43.1
2018
February 7, 2018	February 14, 2018	$	0.60	$	42.7

On April 18, 2019,we declared a distribution of $0.60 per limited partner unit to be paid on May 15, 2019 to unitholders of record on May 8, 2019 with respect to the first quarter of 2019.

Preferred Unit Holders. During the three months endedMarch 31, 2019 and 2018, we made cash distributions to our preferred unitholders of approximately $15.0 million in both periods. On April 18, 2019, the board of directors of our general partner authorized a cash distribution to our preferred unitholders of approximately $15.0 million for the quarter ended March 31, 2019.

Crestwood Midstream

During the three months endedMarch 31, 2019 and 2018, Crestwood Midstream paid cash distributions of $57.8 million and $60.5 million to Crestwood Equity.

Non-Controlling Partner

Crestwood Niobrara LLC (Crestwood Niobrara) issued preferred interests (Series A-2 Preferred Units) to Jackalope Holdings, which are reflected as non-controlling interest in our consolidated financial statements. Subject to certain restrictions, we have the ability to redeem the Series A-2 Preferred Units for an amount in cash or CEQP common units equal to an amount necessary for Jackalope Holdings to achieve a certain rate of return. During the three months endedMarch 31, 2019, Crestwood Niobrara paid cash distributions of $3.3 million to Jackalope Holdings. In April 2019, Crestwood Niobrara paid a cash distribution of $3.3 million to Jackalope Holdings for the quarter ended March 31, 2019.

In conjunction with the acquisition of the remaining 50% equity interest in Jackalope in April 2019, Crestwood Niobrara issued $235 million of preferred interests (Series A-3 Preferred Units) to Jackalope Holdings. Crestwood Niobrara will be required to make quarterly cash distributions on the Series A-3 Preferred Units within 30 days after the end of each quarter beginning with the quarter ended June 30, 2019. In connection with the issuance of the Series A-3 Preferred Units, we entered into a Third Amended and Restated Limited Liability Company Agreement (Crestwood Niobrara Amended Agreement) with Jackalope Holdings for Crestwood Niobrara and modified the provisions related to the redemption and conversion of the Series A-2 and Series A-3 Preferred Units. In addition, we amended our registration rights agreement with Jackalope Holdings and entered into the First Amendment to the Registration Rights Agreement to conform with certain provisions of the Crestwood Niobrara Amended Agreement and the issuance of the Series A-3 Preferred Units.

Other

In February 2019, Crestwood Equity issued 238,263 performance units under the Crestwood Equity Partners LP Long Term Incentive Plan (Crestwood LTIP). The performance units are designed to provide an incentive for continuous employment to certain key employees. The vesting of performance units is subject to the attainment of certain performance and market goals over a three-year period, and entitle a participant to receive common units of Crestwood Equity without payment of an exercise price upon vesting. As of March 31, 2019, we had total unamortized compensation expense of approximately $5.7 million related to these performance units, which we expect will be amortized during the next three years. We recognized compensation expense of approximately $1.4 million under the Crestwood LTIP related to these performance units during the three months ended March 31, 2019, which is included in general and administrative expenses on our consolidated statements of operations.

Note 10 – Commitments and Contingencies

Legal Proceedings

We are periodically involved in litigation proceedings. If we determine that a negative outcome is probable and the amount of loss is reasonably estimable, then we accrue the estimated amount. The results of litigation proceedings cannot be predicted with certainty. We could incur judgments, enter into settlements or revise our expectations regarding the outcome of certain matters, and such developments could have a material adverse effect on our results of operations or cash flows in the period in which the amounts are paid and/or accrued. As of March 31, 2019 and December 31, 2018, both CEQP and CMLP had approximately $0.2 million and $0.1 million accrued for outstanding legal matters. Based on currently available information, we believe it is remote that future costs related to known contingent liability exposures for which we can estimate will exceed current accruals by an amount that would have a material adverse impact on our consolidated financial statements. As we learn new facts concerning contingencies, we reassess our position both with respect to accrued liabilities and other potential exposures.

Any loss estimates are inherently subjective, based on currently available information, and are subject to management’s judgment and various assumptions. Due to the inherently subjective nature of these estimates and the uncertainty and unpredictability surrounding the outcome of legal proceedings, actual results may differ materially from any amounts that have been accrued.

Regulatory Compliance

In the ordinary course of our business, we are subject to various laws and regulations. In the opinion of our management, compliance with current laws and regulations will not have a material effect on our results of operations, cash flows or financial condition.

Environmental Compliance

Our operations are subject to stringent and complex laws and regulations pertaining to worker health, safety, and the environment. We are subject to laws and regulations at the federal, state, regional and local levels that relate to air and water quality, hazardous and solid waste management and disposal, and other environmental matters. The cost of planning, designing, constructing and operating our facilities must incorporate compliance with environmental laws and regulations and safety standards. Failure to comply with these laws and regulations may trigger a variety of administrative, civil and potentially criminal enforcement measures.

During 2014, we experienced three releases totaling approximately 28,000 barrels of produced water on our Arrow water gathering system located on the Fort Berthold Indian Reservation in North Dakota. We immediately notified the National Response Center, the Three Affiliated Tribes and numerous other regulatory authorities. Thereafter, we contained and cleaned up the releases, and placed the impacted segments of these water lines back into service. In May 2015, we experienced a release of approximately 5,200 barrels of produced water on our Arrow water gathering system, immediately notified numerous regulatory authorities and other third parties, and thereafter contained and cleaned up the releases.

In August 2015, we received a notice of violation from the Three Affiliated Tribes’ Environmental Division related to our 2014 produced water releases on the Fort Berthold Indian Reservation. The notice of violation imposes fines and requests reimbursements exceeding $1.1 million; however, the notice of violation was stayed on September 15, 2015. Our discussions regarding the notice of violation continue with the Three Affiliated Tribes.

We will continue our remediation efforts to ensure the impacted lands are restored to their prior state. We believe these releases are insurable events under our policies, and we have notified our carriers of these events. We have not recorded an insurance receivable as of March 31, 2019.

At March 31, 2019 and December 31, 2018, our accrual of approximately $1.8 million was based on our undiscounted estimate of amounts we will spend on compliance with environmental and other regulations, and any associated fines or penalties (including the Arrow water releases described above). We estimate that our potential liability for reasonably possible outcomes related to our environmental exposures could range from approximately $1.8 million to $3.3 million at March 31, 2019.

26

Self-Insurance

We utilize third-party insurance subject to varying retention levels of self-insurance, which management considers prudent. Such self-insurance relates to losses and liabilities primarily associated with medical claims, workers’ compensation claims and general, product, vehicle and environmental liability. Losses are accrued based upon management’s estimates of the aggregate liability for claims incurred using certain assumptions followed in the insurance industry and based on past experience. The primary assumption utilized is actuarially determined loss development factors. The loss development factors are based primarily on historical data. Our self insurance reserves could be affected if future claim developments differ from the historical trends. We believe changes in health care costs, trends in health care claims of our employee base, accident frequency and severity and other factors could materially affect the estimate for these liabilities. We continually monitor changes in employee demographics, incident and claim type and evaluate our insurance accruals and adjust our accruals based on our evaluation of these qualitative data points. We are liable for the development of claims for our disposed retail propane operations, provided they were reported prior to August 1, 2012. The following table summarizes CEQP’s and CMLP’s self-insurance reserves at March 31, 2019 and December 31, 2018 (in millions):

	CEQP				CMLP
	March 31, 2019		December 31, 2018		March 31, 2019		December 31, 2018
Self-insurance reserves(1)	$	11.4	$	11.3	$	10.0	$	9.6

(1) At March 31, 2019, CEQP and CMLP classified approximately $7.4 million and $6.3 million, respectively of these reserves as other long-term liabilities on their consolidated balance sheets.

Guarantees and Indemnifications. We are involved in various joint ventures that sometimes require financial and performance guarantees. In a financial guarantee, we are obligated to make payments if the guaranteed party fails to make payments under, or violates the terms of, the financial arrangement. In a performance guarantee, we provide assurance that the guaranteed party will execute on the terms of the contract. If they do not, we are required to perform on their behalf. We also periodically provide indemnification arrangements related to assets or businesses we have sold. For a further description of our guarantees associated with our joint ventures, see Note 4.

Our potential exposure under guarantee and indemnification arrangements can range from a specified amount to an unlimited dollar amount, depending on the nature of the claim, specificity as to duration, and the particular transaction. As of March 31, 2019 and December 31, 2018, we have no amounts accrued for these guarantees.

Note 11 – Related Party Transactions

Crestwood Holdings indirectly owns both CEQP’s and CMLP’s general partner. The affiliates of Crestwood Holdings and its owners are considered CEQP’s and CMLP’s related parties. We enter into transactions with our affiliates within the ordinary course of business, including gas gathering and processing services under long-term contracts, product purchases and various operating agreements. We also enter into transactions with our affiliates related to services provided on our expansion projects. At March 31, 2019 and 2018, we paid approximately $2.2 million and $0.2 million of capital expenditures to Applied Consultants, Inc., an affiliate of Crestwood Holdings.

Note 13 - Revenues

Contract Assets and Contract Liabilities

Our contract assets and contract liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. Our receivables related to our Topic 606 revenue contracts totaled $225.0 million and $209.7 million for both CEQP and CMLP at March 31, 2019 and December 31, 2018, and are included in accounts receivable on our consolidated balance sheets. Our contract assets are included in other non-current assets on our consolidated balance sheets. Our contract liabilities primarily consist of current and non-current deferred revenues. On our consolidated balance sheets, our current deferred revenues are included in accrued expenses and other liabilities and our non-current deferred revenues are included in other long-term liabilities. The majority of revenues associated with our deferred revenues is expected to be recognized as the performance obligations under the related contracts are satisfied over the next 13 years.

The following table provides a summary of the opening and closing balances of our contract assets and contract liabilities (in millions):

	Balance at March 31, 2019		Balance at December 31, 2018
Contract Assets (Non-current)	$	0.9	$	1.0
Contract Liabilities (Current)(1)	$	12.0	$	12.0
Contract Liabilities (Non-current)(1)	$	71.5	$	65.4

(1) During the three months endedMarch 31, 2019, we recognized revenues of approximately $2.8 million that were previously included in contract liabilities (current) at December 31, 2018. The remaining change in our contract liabilities during the three months endedMarch 31, 2019, primarily related to capital reimbursements associated with our revenue contracts and revenue deferrals associated with our contracts with increasing (decreasing) rates.

The following table summarizes the transaction price allocated to our remaining performance obligations under certain contracts that have not been recognized as of March 31, 2019(in millions):

Remainder of 2019	$	21.4
2020	23.2
2021	9.4
2022	7.3
2023	7.3
Thereafter	3.3
Total	$	71.9

Our remaining performance obligations presented in the table above exclude estimates of variable rate escalation clauses in our contracts with customers, and is generally limited to fixed-fee and percentage-of-proceeds service contracts which have fixed pricing and minimum volume terms and conditions. Our remaining performance obligations generally exclude, based on the following practical expedients that we elected to apply, disclosures for (i) variable consideration allocated to a wholly-unsatisfied promise to transfer a distinct service that forms part of the identified single performance obligation; (ii) unsatisfied performance obligations where the contract term is one year or less; and (iii) contracts for which we recognize revenues as amounts are invoiced.

Disaggregation of Revenues

The following tables summarize our revenues from contracts with customers disaggregated by type of product/service sold and by commodity type for each of our segments for the three months endedMarch 31, 2019 and 2018 (in millions). We believe this summary best depicts how the nature, amount, timing and uncertainty of our revenues and cash flows are affected by economic factors.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Our Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the consolidated financial statements and the accompanying footnotes and Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2018 Annual Report on Form 10-K.

This report, including information included or incorporated by reference herein, contains forward-looking statements concerning the financial condition, results of operations, plans, objectives, future performance and business of our company and its subsidiaries. These forward-looking statements include:

• statements that are not historical in nature, including, but not limited to: (i) our belief that anticipated cash from operations, cash distributions from entities that we control, and borrowing capacity under our credit facility will be sufficient to meet our anticipated liquidity needs for the foreseeable future; (ii) our belief that we do not have material potential liability in connection with legal proceedings that would have a significant financial impact on our consolidated financial condition, results of operations or cash flows; (iii) our belief that our assets will continue to benefit from the development of unconventional shale plays as significant supply basins; and

• statements preceded by, followed by or that contain forward-looking terminology including the words “believe,” “expect,” “may,” “will,” “should,” “could,” “anticipate,” “estimate,” “intend” or the negation thereof, or similar expressions.

Forward-looking statements are not guarantees of future performance or results. They involve risks, uncertainties and assumptions. Actual results may differ materially from those contemplated by the forward-looking statements due to, among others, the following factors:

• our ability to successfully implement our business plan for our assets and operations;

• governmental legislation and regulations;

• industry factors that influence the supply of and demand for crude oil, natural gas and NGLs;

• industry factors that influence the demand for services in the markets (particularly unconventional shale plays) in which we provide services;

• weather conditions;

• the availability of crude oil, natural gas and NGLs, and the price of those commodities, to consumers relative to the price of alternative and competing fuels;

• economic conditions;

• costs or difficulties related to the integration of acquisitions and success of our joint ventures’ operations;

• environmental claims;

• operating hazards and other risks incidental to the provision of midstream services, including gathering, compressing, treating, processing, fractionating, transporting and storing energy products (i.e., crude oil, NGLs and natural gas) and related products (i.e., produced water);

• interest rates;

• the price and availability of debt and equity financing, including our ability to raise capital through alternatives like joint ventures; and

• the ability to sell or monetize assets, to reduce indebtedness, to repurchase our equity securities, to make strategic investments, or for other general partnership purposes.

For additional factors that could cause actual results to be materially different from those described in the forward-looking statements, see Part I, Item 1A. Risk Factors of our 2018 Annual Report on Form 10-K.

Outlook and Trends

Our business objective is to create long-term value for our unitholders. We expect to create long-term value by consistently generating stable operating margin and improved cash flows from operations by prudently financing our investments, maximizing throughput on our assets, and effectively controlling our operating and administrative costs. Our business strategy depends, in part, on our ability to provide increased services to our customers at competitive fees, including opportunities to expand our services resulting from expansions, organic growth projects and acquisitions that can be financed appropriately.

40

We have taken a number of strategic steps to better position the Company as a stronger, better capitalized company that can over time accretively grow cash flows and sustainably resume growing our distributions. Those strategic steps included (i) simplifying our corporate structure to eliminate our incentive distribution rights (IDRs) and create better alignment of interests with our unitholders; (ii) divesting assets to reduce long-term debt to ensure long-term balance sheet strength; (iii) realigning our operating structure to significantly reduce operating and administrative expenses; (iv) forming strategic joint ventures to enhance our competitive position around certain operating assets; and (v) focusing our acquisitions and growth capital expenditures on our highest return organic projects around our core growth assets in the Bakken Shale, Powder River Basin and Delaware Permian. We will remain focused on efficiently allocating capital expenditures by investing in accretive, organic growth projects, maintaining low-cost operations (through increased operating efficiencies and cost discipline) and maintaining our balance sheet strength through continued financial discipline. We expect to focus on expansion and greenfield opportunities to provide midstream services for crude oil, natural gas, NGLs and produced water, including gathering, storage and terminalling, condensate stabilization, truck loading/unloading options and connections to third party pipelines and produced water gathering, disposal and recycling in the Bakken Shale, Powder River Basin and Delaware Permian in the near term, while closely monitoring longer-term expansion opportunities in the northeast Marcellus. As a result, the Company is well positioned to execute its business plan and capitalize on improving market conditions.

The Company continues to be positioned to generate consistent results in a low commodity price environment without sacrificing revenue upside as market conditions improve. For example, many of our more mature G&P assets are supported by long-term, core acreage dedications in shale plays that are economic to varying degrees based upon natural gas, NGL and crude oil prices, the availability of infrastructure to flow production to market, and the operational and financial condition of our diverse customer base. In addition, a substantial portion of our midstream investments are based on fixed-fee or minimum volume commitment agreements that ensure a minimum level of cash flow regardless of actual commodity prices or volumetric throughput. Over time, we expect cash flows from our more mature, non-core, assets to stabilize and potentially increase with the improving commodity price environment, while the growth from our core assets in the Bakken Shale, Powder River Basin, Delaware Permian and northeast Marcellus drive significant growth to the Company.

Business Highlights

Below is a discussion of events that highlight our core business and financing activities. Through continued execution of our plan, we have materially improved the strategic and financial position of the Company and expect to capitalize on increasing opportunities in an improving but competitive market environment, which will position us to achieve our chief business objective to create long-term value for our unitholders.

Powder River Basin. In the Powder River Basin, our Jackalope joint venture with Williams continues to benefit from increased drilling activity and better than anticipated well results. Jackalope is expanding its gathering system and Bucking Horse processing plant to increase processing capacity to 345 MMcf/d in late 2019/early 2020. The Phase 2 Jackalope expansion also includes gathering, compression and a second processing plant which will add an additional 200 MMcf/d to the Jackalope system.

On April 9, 2019, Crestwood Niobrara, our consolidated subsidiary, acquired Williams’s 50% equity interest in Jackalope for approximately $484.6 million. The acquisition of the remaining 50% equity interest in Jackalope was financed through a combination of borrowings under the CMLP credit facility and the issuance of $235 million in new preferred units to Jackalope Holdings. Crestwood Midstream Operating, our consolidated subsidiary, will provide field operations and construction management services for Jackalope. For a further discussion of the acquisition of the remaining 50% equity interest in Jackalope, see Item I. Financial Statements, Notes 4 and 9.

Bakken. In the Bakken, we are expanding and upgrading our Arrow system water handling facilities and increasing natural gas capacity on the system, which should allow for substantial growth in volumetric throughput across all of our crude oil, produced water and natural gas gathering systems. In addition, we are constructing a 120 MMcf/d cryogenic plant that we anticipate will be placed in-service in the third quarter of 2019 to fulfill 100% of the processing requirements for producers on the Arrow system upon expiration of third-party processing contracts in the third quarter 2019. Upon completion of the expansion, we expect to have 150 MMcf/d of gas processing capacity in the Bakken. We believe the expansion of our gas processing capacity on the Arrow system will, among other things, spur greater development activity around the Arrow system, allow us to provide greater flow assurance to our producer customers and reduce flaring of natural gas, and reduce the downstream constraints currently experienced by producers on the Fort Berthold Indian Reservation.

Delaware Permian. In the Delaware Permian, we have identified gathering and processing and transportation opportunities in and around our existing assets, including our Crestwood Permian joint venture. Crestwood Permian Basin owns and operates the Nautilus system in SWEPI's operated position in the Delaware Permian, which will be constructed to ultimately include 194

41

miles of low pressure gathering lines, 36 miles of high pressure trunklines and centralized compression facilities which are expandable over time as production increases, producing gas gathering capacity of approximately 250 MMcf/d.

Regulatory Matters

Our regulatory matters are discussed in our 2018 Annual Report on Form 10-K and there have been no material changes in those matters from December 31, 2018 to March 31, 2019.

Critical Accounting Estimates

Our critical accounting estimates are consistent with those described in our 2018 Annual Report on Form 10-K.

How We Evaluate Our Operations

We evaluate our overall business performance based primarily on EBITDA and Adjusted EBITDA. We do not utilize depreciation, amortization and accretion expense in our key measures because we focus our performance management on cash flow generation and our assets have long useful lives.

EBITDA and Adjusted EBITDA - We believe that EBITDA and Adjusted EBITDA are widely accepted financial indicators of a company’s operational performance and its ability to incur and service debt, fund capital expenditures and make distributions. We believe that EBITDA and Adjusted EBITDA are useful to our investors because it allows them to use the same performance measure analyzed internally by our management to evaluate the performance of our businesses and investments without regard to the manner in which they are financed or our capital structure. EBITDA is defined as income before income taxes, plus interest and debt expense, net and depreciation, amortization and accretion expense. Adjusted EBITDA considers the adjusted earnings impact of our unconsolidated affiliates by adjusting our equity earnings or losses from our unconsolidated affiliates to reflect our proportionate share (based on the distribution percentage) of their EBITDA, excluding impairments. Adjusted EBITDA also considers the impact of certain significant items, such as unit-based compensation charges, gains or losses on long-lived assets, third party costs incurred related to potential and completed acquisitions, certain environmental remediation costs, the change in fair value of commodity inventory-related derivative contracts, costs associated with the realignment of our Marketing, Supply and Logistics and Corporate operations and other transactions identified in a specific reporting period. The change in fair value of commodity inventory-related derivative contracts is considered in determining Adjusted EBITDA given that the timing of recognizing gains and losses on these derivative contracts differs from the recognition of revenue for the related underlying sale of inventory to which these derivatives relate. Changes in the fair value of other derivative contracts is not considered in determining Adjusted EBITDA given the relatively short-term nature of those derivative contracts. EBITDA and Adjusted EBITDA are not measures calculated in accordance with GAAP, as they do not include deductions for items such as depreciation, amortization and accretion, interest and income taxes, which are necessary to maintain our business. EBITDA and Adjusted EBITDA should not be considered as alternatives to net income, operating cash flow or any other measure of financial performance presented in accordance with GAAP. EBITDA and Adjusted EBITDA calculations may vary among entities, so our computation may not be comparable to measures used by other companies.

See our reconciliation of net income to EBITDA and Adjusted EBITDA in Results of Operations below.

Below is a discussion of the factors that impacted EBITDA by segment for the three months endedMarch 31, 2019 compared to the same period in 2018.

Gathering and Processing

EBITDA for our gathering and processing segment decreased by approximately $5.0 million during the three months ended March 31, 2019 compared to the same period in 2018. The decrease was primarily driven by a $5.9 million decrease in our earnings from unconsolidated affiliates, which is further described below. Our gathering and processing segment’s revenues decreased by approximately $146.5 million during the three months ended March 31, 2019 compared to the same period in 2018, while our costs of product/services sold decreased by approximately $149.7 million period-over-period. These variances were primarily driven by our Arrow operations which experienced lower average prices on its agreements under which it

44

purchases and sells crude oil as a result of the decrease in crude oil prices during the three months ended March 31, 2019 compared to the same period in 2018. Our costs of product/services sold decreased faster than our revenues period over period due to the offsetting impact of increasing volumes, as during the three months ended March 31, 2019, natural gas, crude oil and water volumes gathered by our Arrow system increased by 18%, 16% and 44%, respectively, compared to the same period in 2018.

Our gathering and processing segment’s operations and maintenance expenses were relatively flat during the three months ended March 31, 2019 compared to the same period in 2018.

Our gathering and processing segment’s EBITDA during the three months ended March 31, 2019 includes a loss on long-lived assets of approximately $1.8 million primarily related to the disposal of our Granite Wash gathering and processing assets.

Our gathering and processing segment’s EBITDA was also impacted by a net decrease in earnings from unconsolidated affiliates of approximately $5.9 million during the three months ended March 31, 2019 compared to the same period in 2018. The decrease was primarily driven by a $6.1 million decrease in equity earnings from Crestwood Permian resulting from a loss on the retirement of certain of its gathering and processing assets and an increase in its depreciation, amortization and accretion expense due to the in-service of its Orla processing plant in mid-2018. Partially offsetting this decrease was an increase in equity earnings from Jackalope of approximately $0.2 million. In April 2019, Crestwood Niobrara acquired the remaining 50% equity interest in Jackalope from Williams, and as a result, we will reflect 100% of the operating results of Jackalope in our operating results beginning in the second quarter of 2019.

Storage and Transportation

EBITDA for our storage and transportation segment increased by approximately $5.5 million during the three months ended March 31, 2019 compared to the same period in 2018, primarily due to an increase in revenues of approximately $5.2 million from our COLT Hub operations. During the three months ended March 31, 2019, we recognized approximately $4.0 million of revenues under a take-or-pay contract with one of our rail loading customers that expires in 2019. In addition, during the three months ended March 31, 2019, COLT’s rail loading volumes increased by 63% compared to the same period in 2018 due to higher demand for rail loading services resulting from higher Bakken crude oil production and higher basis differentials between the Bakken and the U.S. western and eastern markets.

Our storage and transportation segment’s operations and maintenance expenses were relatively flat during the three months ended March 31, 2019 compared to the same period in 2018.

Our storage and transportation segment’s EBITDA was also impacted by a net increase in earnings from unconsolidated affiliates during the three months ended March 31, 2019 compared to the same period in 2018. Earnings from our Stagecoach Gas equity investment increased by approximately $1.3 million primarily due to our share of Stagecoach Gas’s equity earnings increasing from 35% to 40% effective July 1, 2018. Effective July 1, 2019, our equity earnings from Stagecoach Gas will be allocated based on our ownership percentage, which is currently 50%. Partially offsetting this increase was lower equity earnings from our PRBIC equity investment of approximately $0.7 million due to the expiration of a rail loading contract with one of its customers in mid-2018.

Marketing, Supply and Logistics

EBITDA for our marketing, supply and logistics segment decreased by approximately $12.0 million during the three months ended March 31, 2019 compared to the same period in 2018, primarily driven by lower revenues of approximately $138.5 million and lower costs of approximately $120.4 million.

Our marketing, supply and logistics results for the three months ended March 31, 2019 were impacted by the sale of our West Coast assets in late 2018, which resulted in lower revenues of approximately $98.2 million and lower costs of product/services sold of approximately $90.0 million compared to the same period in 2018. In addition, the sale of our West Coast assets also resulted in lower operations and maintenance expenses of approximately $5.4 million.

Our NGL marketing and logistics operations (other than West Coast) experienced a reduction in its revenues and costs of product/services sold of approximately $131.6 million and $115.5 million during the three months ended March 31, 2019 compared to the same period in 2018. Included in our costs of product/services sold was a loss of $2.9 million during the three months ended March 31, 2019 compared to a gain of $7.8 million during the same period in 2018 related to the change in fair value of our derivative instruments. The remaining decrease in revenues and product costs was driven primarily by lower NGL prices during the first quarter of 2019 compared to 2018, which impacted the gross realized values of our NGL purchases and

45

sales during the first quarter of 2019 and decreased trucking and throughput volumes on our NGL assets by approximately 11% when compared to the same period in 2018.

Our crude and natural gas marketing operations experienced an increase in its revenues and product costs of approximately $90.5 million and $84.1 million during the three months ended March 31, 2019 compared to the same period in 2018. These increases were driven by higher crude marketing volumes due to increased marketing activity surrounding our crude-related operations.

Other EBITDA Results

General and Administrative Expenses. During the three month ended March 31, 2019, our general and administrative expenses increased by approximately $13 million compared to the same period in 2018, primarily due to an increase in unit-based compensation charges based on the acceleration of certain awards due to the Corporate restructuring that occurred in early 2019, higher average awards outstanding under our long-term incentive plans and the impact of higher allocations of unit-based compensation costs from Crestwood Holdings.

Items not affecting EBITDA include the following:

Depreciation, Amortization and Accretion Expense. During the three months ended March 31, 2019, our depreciation, amortization and accretion expense decreased compared to the same period in 2018, primarily due to the sale of our West Coast assets in late 2018.

Interest and Debt Expense, Net. During the three months ended March 31, 2019, interest and debt expense, net increased by approximately $0.5 million compared to the same period in 2018 due to higher outstanding balances on our credit facility that were primarily utilized to fund growth capital expenditures during the first quarter of 2019. The following table provides a summary of interest and debt expense (in millions):

	Three Months Ended
	March 31,
	2019		2018
Credit facility	$	7.9	$	5.0
Senior notes	18.1		18.1
Other debt-related costs	1.6		1.8
Gross interest and debt expense	27.6		24.9
Less: capitalized interest	2.7		0.5
Interest and debt expense, net	$	24.9	$	24.4

Liquidity and Sources of Capital

Crestwood Equity is a holding company that derives all of its operating cash flow from its operating subsidiaries.  Our principal sources of liquidity include cash generated by operating activities from our subsidiaries, distributions from our joint ventures, borrowings under the CMLP credit facility, and sales of equity and debt securities. Our equity investments use cash from their respective operations to fund their operating activities, maintenance and growth capital expenditures, and service their outstanding indebtedness. We believe our liquidity sources and operating cash flows are sufficient to address our future operating, debt service and capital requirements.

We make cash quarterly distributions to our common unitholders within approximately 45 days after the end of each fiscal quarter in an aggregate amount equal to our available cash for such quarter. We also pay cash quarterly distributions of approximately $15 million to our preferred unitholders. We believe our operating cash flows will well exceed cash distributions to our partners and our preferred unitholders at current levels, and as a result, we will have substantial operating cash flows as a source of liquidity for our growth capital expenditures.

As of March 31, 2019, we had $584.0 million of available capacity under the credit facility considering the most restrictive debt covenants in the credit agreement. As of March 31, 2019, we were in compliance with all of our debt covenants applicable to the credit facility and senior notes.

46

In April 2019, Crestwood Niobrara acquired Williams’s 50% equity interest in Jackalope for approximately $484.6 million. The acquisition of the remaining 50% equity interest in Jackalope was funded through a combination of borrowings under the CMLP credit facility and the issuance of $235 million of new preferred units to Jackalope Holdings. Contemporaneously with the closing of the remaining interest in Jackalope, Crestwood Midstream entered into the First Amendment to the Second Amended and Restated Credit Agreement to modify certain defined terms and calculations, among other things, to account for the Jackalope acquisition. The other debt covenants under the amended credit agreement are materially consistent with the credit facility that existed at March 31, 2019.

In April 2019, Crestwood Midstream issued $600 million of 5.625% unsecured senior notes due 2027. The net proceeds from this offering of approximately $591.1 million were used to repay a portion of the outstanding borrowings under the CMLP credit facility, which includes approximately $250 million of borrowings that were used to fund the acquisition of the remaining 50% equity interest in Jackalope.

We may from time to time seek to retire or purchase our outstanding debt through cash purchases and/or exchanges for equity securities, in open market purchases, privately negotiated transactions, tender offers or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

Cash Flows

The following table provides a summary of Crestwood Equity’s cash flows by category (in millions):

	Three Months Ended
	March 31,
	2019			2018
Net cash provided by operating activities	$	130.9		$	148.7
Net cash used in investing activities	$	(91.0	)	$	(52.7	)
Net cash used in financing activities	$	(55.3	)	$	(90.0	)

Operating Activities

Our operating cash flows decreased by approximately $17.8 million during the three months ended March 31, 2019 compared to the same period in 2018, primarily due to a decrease in operating revenues of approximately $279.8 million driven primarily by our marketing, supply and logistics segment’s operations, which was impacted by the sale of our West Coast assets in late 2018 discussed above. Partially offsetting this decrease was lower costs of product/services sold of approximately $270.2 million primarily from that segment. The decrease in net operating cash flows was also impacted by an $8.7 million reduction in net cash inflow from working capital requirements, primarily from our marketing, supply and logistics segment.

Investing Activities

Capital Expenditures. The energy midstream business is capital intensive, requiring significant investments for the acquisition or development of new facilities. We categorize our capital expenditures as either:

• growth capital expenditures, which are made to construct additional assets, expand and upgrade existing systems, or acquire additional assets; or

• maintenance capital expenditures, which are made to replace partially or fully depreciated assets, to maintain the existing operating capacity of our assets, extend their useful lives or comply with regulatory requirements.

Adjusting for the acquisition of the remaining 50% equity interest in Jackalope, our growth capital expenditures and contributions to our joint ventures during 2019 will be approximately $425 million to $475 million. We anticipate that our growth and reimbursable capital expenditures for the remainder of 2019 will increase the services we can provide to our customers and the operating efficiencies of our systems. We expect to finance our capital expenditures with a combination of cash generated by our operating subsidiaries, distributions received from our equity investments and borrowings under our credit facility.

We have identified growth capital project opportunities for our reporting segments. Additional commitments or expenditures will be made at our discretion, and any discontinuation of the construction of these projects will likely result in less future cash

flows and earnings. The following table summarizes our capital expenditures for the three months endedMarch 31, 2019 (in millions).

Growth capital	$	60.0
Maintenance capital	1.4
Other (1)	7.1
Purchases of property, plant and equipment	$	68.5

(1) Represents purchases of property, plant and equipment that are reimbursable by third parties.

Investments in Unconsolidated Affiliates. During the three months endedMarch 31, 2019, we contributed approximately $38.2 million to our equity investments primarily to fund their expansion projects.

Financing Activities

The following equity and debt transactions impacted our financing activities during the three months endedMarch 31, 2019:

• During the three months ended March 31, 2019, we distributed approximately $3.3 million to our non-controlling partner.

• During the three months ended March 31, 2019, our debt-related transactions resulted in net borrowings of approximately $14.3 million compared to net repayments of approximately $25.6 million during the same period in 2018.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Our interest rate risk and commodity price and market risks are discussed in our 2018 Annual Report on Form 10-K and there have been no material changes in those exposures from December 31, 2018 to March 31, 2019.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

As of March 31, 2019, Crestwood Equity and Crestwood Midstream carried out an evaluation under the supervision and with the participation of their respective management, including the Chief Executive Officer and Chief Financial Officer of their General Partners, as to the effectiveness, design and operation of our disclosure controls and procedures (as defined in the Securities Exchange Act of 1934, as amended (Exchange Act) Rules 13a-15(e) and 15d-15(e)). Crestwood Equity and Crestwood Midstream maintain controls and procedures designed to provide reasonable assurance that information required to be disclosed in their respective reports that are filed or submitted under the Exchange Act of 1934, as amended, are recorded, processed, summarized and reported within the time periods specified by the rules and forms of the SEC, and that information is accumulated and communicated to their respective management, including the Chief Executive Officer and Chief Financial Officer of their General Partners, as appropriate, to allow timely decisions regarding required disclosure. Such management, including the Chief Executive Officer and Chief Financial Officer of their General Partners, do not expect that the disclosure controls and procedures or the internal controls will prevent and/or detect all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Crestwood Equity’s and Crestwood Midstream’s disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives and our Chief Executive Officer and Chief Financial Officer of their General Partners concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of March 31, 2019.

Changes in Internal Control over Financial Reporting

There were no changes to Crestwood Equity’s or Crestwood Midstream’s internal control over financial reporting during the three months endedMarch 31, 2019 that have materially affected, or are reasonably likely to materially affect Crestwood Equity’s or Crestwood Midstream’s internal control over financial reporting.

Pursuant to Sections 3.1(b)(i) and 3.3(a)(ii) of the Second Amended and Restated Employment Agreement, by and between Employee and the Company, dated July 21, 2017 (the “Employment Agreement”), the Company hereby provides Employee notice that the Employment Agreement and Employee’s employment thereunder shall terminate effective April 15, 2019 (the “Separation Date”).Employee acknowledges and agrees that, other than for salary payable through the Separation Date and as otherwise set forth herein, Employee is not entitled to any additional compensation, payments, salary, wages, benefits, or other remuneration from the Company under the Employment Agreement or otherwise.

2.Cessation of Benefits. Employee’s eligibility to participate in any of the Company’s benefits and plans shall cease effective the Separation Date. To the extent that Employee participated in the Company’s group medical and dental plans, Employee may be eligible for continuation of medical and dental coverage as provided for in the Consolidated Omnibus Budget Reconciliation Act of 1985. Employee understands that continued health insurance coverage requires Employee’s timely and proper completion of the COBRA enrollment form received from the administrative services provider.

3.Equity Interests. During Employee’s employment with the Company, Employee received certain awards of restricted and performance units, which are each governed by the terms and conditions of the applicable award agreements and plan documents (collectively, the “Award Agreements”). The restricted and performance units were granted from the Crestwood Equity Partners LP Long Term Incentive Plan (the “Plan”). Employee acknowledges and agrees that he is not entitled to any further equity awards pursuant to Section 2.2 of the Employment Agreement or otherwise. The termination of Employee’s employment with the Company is deemed to be a termination by the Employer without Cause (as defined in the Plan). Any units granted pursuant to the Award Agreements that have not yet vested shall fully vest on the Separation Date, except for those performance units issued on February 15, 2017, which shall vest on February 15, 2020.

4.Severance Payment. Pursuant to Section 3.3(b)(i) of the Employment Agreement, and in exchange for Employee’s promises set forth in this Agreement, the Company shall pay Employee a severance payment in the amount of Two Million, Eight Hundred and Four Thousand, Four Hundred and Eleven Dollars and No Cents ($2,804,411.00), less applicable taxes and withholdings (the “Severance Payment”), which represents two times the sum of Employee’s Base Salary and the average of the annual Bonus paid to Employee for the prior 2-year period. The Severance Payment shall be payable in equal installments in accordance with the Company’s normal payroll procedures during the twelve (12) month period following the Separation Date; provided however, that the Company’s obligation to make the Severance Payment shall be expressly conditioned upon (a) Employee’s timely execution and non-revocation of this Agreement; (b) Employee’s compliance with his continuing obligations set forth in Section 4 of the Employment

1

Agreement (including all sub-parts thereto), which by their terms survive termination of the Employment Agreement. Payment of the first and any subsequent installments of the Severance Payment shall be delayed until such time that Employee has executed this Agreement and delivered it to the Company and the revocation period set forth in Section 8(h) has expired without revocation by Employee. Employee acknowledges and agrees that the Severance Payment provided for in this Section 4 fully satisfies any and all monetary severance obligations of the Company pursuant to Section 3.3(b)(i) of the Employment Agreement.

5.COBRA Continuation Benefit. Pursuant to Section 3.3(b)(i) of the Employment Agreement, during the period that Employee is entitled to receive Severance Payment installments hereunder, the Company shall pay on Employee’s behalf, or reimburse Employee for, a portion of Employee’s COBRA continuation premiums equal to the employer portion of the premiums paid by the Company on behalf of an active employee (the “COBRA Benefit”); provided, however, that the Company’s obligation to provide the COBRA Benefit shall be expressly conditioned upon (a) Employee’s timely execution and non-revocation of this Agreement; (b) Employee’s timely and proper completion of the COBRA enrollment form received from the administrative services provider; (c) Employee’s timely payment of the remaining premium amounts owed by Employee for such continuation coverage; and (d) Employee’s compliance with his continuing obligations set forth in Section 4 of the Employment Agreement (including all sub-parts thereto), which by their terms survive termination of the Employment Agreement. The foregoing notwithstanding, the Company’s obligation to provide the COBRA Benefit shall cease on the first day of the month after Employee obtains reasonably comparable health care coverage from a subsequent employer or other source, regardless of whether Employee remains entitled to receive Severance Payment installments.

6.Severance Waiver Notice. In the event Employee delivers a Severance Waiver Notice as defined in and pursuant to Section 4.1 of the Employment Agreement, Employee shall no longer be bound by the non-competition obligation set forth in Section 4.1 of the Employment Agreement, but shall continue to be bound by all other obligations set forth in Section 4 of the Employment Agreement, including Employee’s obligations regarding non-solicitation and non-disclosure of confidential information. The Company shall be immediately released from the obligation to pay any further installments of the Severance Payment and COBRA Benefit upon Employee’s delivery of a Severance Waiver Notice. Pursuant to Section 3.9 of the Employment Agreement, which shall remain in full force and effect, Employee acknowledges that in the event Employee breaches the non-competition obligation set forth in Section 4.1 of the Employment Agreement prior to delivery of a Severance Waiver Notice, or otherwise breaches any of the other obligations set forth in Section 4, Employee shall fully, completely and permanently forfeit any and all rights to the Severance Payment and COBRA Benefit.

7.Employee Release. In exchange for the Severance Payment and COBRA Benefit, as well as the other promises set forth in this Agreement, Employee voluntarily and knowingly waives, releases, and discharges the Company, its direct and indirect parent companies, predecessor, successor, subsidiary, and affiliate companies, and all of their respective employees, officers, directors, owners, members, shareholders, principals, attorneys, insurers, benefit plans, plan fiduciaries, representatives, agents and assigns (collectively, the “Released Parties”) from all

-28-

3.11Tag-Along Right.

(a)Following a Conversion, if the Crestwood Member desires to Transfer, or effect or permit an indirect transfer of, all or any portion of its Units in the Company other than to an Affiliate and other than pursuant to an Excluded Indirect Crestwood Transfer, then (i) the Holdings Member shall have the right (but not the obligation) (the “Tag-Along Right,” and the Units held by the Crestwood Member, the “Tag Interest”) to participate in the proposed transaction (the “Tag-Along Transfer”) and (ii) the Crestwood Member shall make an offer (a “Tag-Along Offer”) by an irrevocable written notice to the Holdings Member, to include in the Tag-Along Transfer, on terms and conditions set forth in such notice (which must be at least as favorable to the Holdings Member as to the Crestwood Member), a number of the Holdings Member’s Units in accordance with the provisions of this Section 3.11.

(b)Pursuant to the Tag-Along Right, (i) in the case of a Tag-Along Transfer that is a Transfer of Units, the Holdings Member shall have the right to Transfer in such Tag-Along Transfer the same percentage of its Units as the percentage of the Crestwood Member’s aggregate Units that the Crestwood Member is proposing to Transfer and (ii) in the case of a Tag-Along Transfer that is an indirect transfer, the Holdings Member shall have the right to Transfer in such Tag-Along Transfer the same percentage of its Units as the percentage of equity interests in the Crestwood Member being directly or indirectly transferred in such Tag-Along Transfer. If the Crestwood Member is unable to cause the transferee to purchase all of the Units proposed to be sold directly or indirectly by the Crestwood Member and the Holdings Member, then the Crestwood Member and the Holdings Member shall reduce, on a pro rata basis, the amount of such Units that each otherwise would have sold so as to permit the Crestwood Member and the Holdings Member to sell directly or indirectly the number of Units (determined in accordance with such pro rata basis) that the proposed transferee is willing to purchase.

(c)The Tag-Along Offer may be accepted by the Holdings Member at any time within 30 days after the Holdings Member’s receipt of the Tag-Along Offer (such period, the “Tag-Along Notice Period”), which acceptance must be made by delivery of a written notice indicating such acceptance to the Crestwood Member (such notice, the “Tag-Along Acceptance”). If the Holdings Member exercises the Tag-Along Right, then the Holdings Member’s Units shall be

-29-

purchased on the same terms and conditions as the Tag Interest (provided, that in the case of a Tag-Along Transfer involving the direct or indirect transfer of an equity interest in which the equity interest being transferred represents an ownership interest in anything other than an indirect ownership interest in the Crestwood Member’s Units, then the purchase price to be paid in respect of the Holdings Member’s Units shall equal the Fair Market Value thereof); provided that any representations and warranties relating specifically to any Member shall be made only by such Member.

(d)If (i) the Holdings Member does not deliver a Tag-Along Acceptance within the Tag-Along Notice Period or (ii) the Tag-Along Transfer fails to close for any reason other than due to a breach by the Crestwood Member of its obligation to consummate the Tag-Along Transfer, then the Crestwood Member (or the applicable indirect transferor) may, during the 180-day period following the expiration of the Tag-Along Notice Period (which period may be extended for a reasonable time not to exceed an additional 60 days to the extent reasonably necessary to obtain any required government or other third party approvals) (the “Tag-Along Transfer Period”) consummate the Tag-Along Transfer with only the Tag Interest; provided that, in either such case, the Tag-Along Transfer is subject to a price no greater than the price set forth in the Tag-Along Offer and on other terms and conditions in the aggregate no more favorable to the transferee than those set forth in the Tag-Along Offer.

(e)If the Crestwood Member (or the applicable indirect transferor) does not sell the Tag Interest in the Tag-Along Transfer Period, the Crestwood Member must again comply with the provisions set forth in this Section 3.11, to the extent applicable, prior to making any subsequent sale of all or any portion of its Units or effecting or permitting any indirect transfer of all or any portion of Units.

Article IVCAPITAL CONTRIBUTIONS; REDEMPTIONS OF PREFERRED UNITS

4.01Interests.Each Member’s Interest in the Company will be represented by its Capital Account and by Units issued by the Company to such Member. The classes of authorized Units as of the Effective Date are the Series A-2 Preferred Units, the Series A-3 Preferred Units, the Series B Preferred Units, the Series C Preferred Units and the Common Units (it being understood that all of the Series A-1 Preferred Units (as defined in the Prior LLC Agreement) issued under the Prior LLC Agreement were redeemed and extinguished on the Issue Date). Except as expressly set forth herein, the Units have no voting rights and do not confer the right to vote on matters related to the Company or otherwise. The obligations of each Member hereunder shall be several and not joint, and no Member shall be obligated to make any of the Capital Contributions of another Member.

4.02Capital Contributions.

(a)Capital Contributions. On the Issue Date, all of the Series A-1 Preferred Units (as defined in the Prior LLC Agreement) issued under the Prior LLC Agreement were redeemed and extinguished and the Company issued 175,000,000 Series A-2 Preferred Units to the Holdings Member. On the Effective Date, the Company issued the number of Series A-3 Preferred Units to the Holdings Member as set forth opposite the Holdings Member’s name on Exhibit A, and the

-30-

aggregate amount of Capital Contributions made by the Holdings Member in respect of such Series A-3 Preferred Units is also set forth opposite the Holdings Member’s name on Exhibit A. As of the Effective Date, the Crestwood Member has contributed $462,406,523 to the Company and holds the number of Common Units set forth opposite the Crestwood Member’s name on Exhibit A.

(b)Pre-Conversion Capital Contributions by Members.

(i)Until the occurrence of a Conversion, the Crestwood Member may, in its sole discretion, elect to require the Holdings Member to fund any Agreed Midstream Project as set forth in this Section 4.02(b)(i) (the total amount required from all Members to fund any such Agreed Midstream Project being the “Total Project Capital Contribution”). Any such election shall be exercised by delivering a written notice in compliance with Section 4.02(d) to the Holdings Member. If the Crestwood Member makes such an election and delivers such notice, then, on the funding dates set out in such notice, (A) the Holdings Member will be required to fund an amount equal to the product of the then-current Aggregate Conversion Ratio and the Total Project Capital Contribution (subject to any approvals or other limitations as may be set out in the applicable Project Request) by making Capital Contributions to the Company (Holdings Member’s share of each such capital contribution, an “Accordion Capital Contribution”), it being understood that the amount of such Accordion Capital Contribution that is equal to the product of the A-2 Conversion Ratio and the Total Project Capital Contribution shall be borne by the holders of the Series A-2 Preferred Units and the amount of such Accordion Capital Contribution that is equal to the product of the A-3 Conversion Ratio and the Total Project Capital Contribution shall be borne by the holders of the Series A-3 Preferred Units, and (B) the Crestwood Member will be required to fund the balance of all amounts required in connection with such Agreed Midstream Project by making Capital Contributions to the Company (each such required contribution, a “Crestwood Additional Capital Contribution”). Notwithstanding anything herein to the contrary, if any Accordion Capital Contribution or Crestwood Additional Capital Contribution with respect to an Agreed Midstream Project has been approved but not fully funded prior to a Conversion, then after such Conversion, such Accordion Capital Contribution or Crestwood Additional Capital Contribution will continue to be required to be made (and Section 4.02(b)(i) shall be disregarded with respect thereto) except that, instead of issuing Series A-2 Preferred Units or Series A-3 Preferred Units to any Member that is funding an Accordion Capital Contribution (or Common Units based on the Common Unit Price in respect of Crestwood Additional Capital Contributions), the Company shall issue to each Member that is so funding a number of Common Units equal to the amount of such Accordion Capital Contribution or Crestwood Additional Capital Contribution made by such Member (as the case may be) divided by the Fair Market Value of a Common Unit. In the event that, prior to a Conversion, the Crestwood Member (i) does not elect to require an Accordion Capital Contribution in respect of an Agreed Midstream Project, or (ii) causes the Company to pursue a De Minimis Midstream Project Opportunity or Crestwood Scheduled Project pursuant to Section 6.03(e) and Section 6.03(f), respectively, any Capital Contribution required in connection therewith shall be considered a Crestwood Additional Capital Contribution.

-31-

(ii)Notwithstanding the foregoing, once the Holdings Member has made aggregate Accordion Capital Contributions at least equal to the Maximum Holdings Member Accordion Amount, the Holdings Member will have no further obligation to make any further Accordion Capital Contributions to the Company, and the Holdings Member shall not be required to make Accordion Capital Contributions at any time at which either any Series B Preferred Units are outstanding or any Series A Quarterly Distribution required to have been distributed in cash has not been paid in full in accordance with Section 5.01(a). For the avoidance of doubt, (I) if (x) the Crestwood Member makes an election to require the Holdings Member to fund any Agreed Midstream Project at a time at which the aggregate amount of all Accordion Capital Contributions attributable to the outstanding Series A Preferred Units as of immediately prior to such election (the “Prior Aggregate Accordion Amount”) does not exceed the Maximum Holdings Member Accordion Amount and (y) the excess of the Maximum Holdings Member Accordion Amount minus the Prior Aggregate Accordion Amount is an amount less than the product of the Aggregate Conversion Ratio and all amounts required in connection with an Agreed Midstream Project, then the Accordion Capital Contribution of the Holdings Member pursuant to such election shall be reduced to such excess amount and the Crestwood Additional Capital Contribution relating to such Agreed Midstream Project shall be increased accordingly and (II) the Maximum Holdings Member Accordion Amount shall not be reduced by any Series A-2 PIK Distribution. Except as provided in the penultimate sentence of Section 4.02(b)(i), immediately upon receipt by the Company of: (A) any Accordion Capital Contribution by the Company, the Company shall issue to the Holdings Member (1) a number of Series A-2 Preferred Units equal to the amount of such Accordion Capital Contributions made by the Holdings Member in respect of its Series A-2 Preferred Units divided by the Series A-2 Preferred Unit Price and (2) a number of Series A-3 Preferred Units equal to the amount of such Accordion Capital Contribution made by the Holdings Member in respect of its Series A-3 Preferred Units divided by the Series A-3 Preferred Unit Price and (B) any Crestwood Additional Capital Contribution, the Company shall issue to the Crestwood Member a number of Common Units equal to the amount of such Crestwood Additional Capital Contribution divided by the Common Unit Price.

(iii)The Parties acknowledge and agree that, immediately following any acquisition of Series A Preferred Units by the Crestwood Member pursuant to Section 3.04, all obligations of the “Holdings Member” set forth in the foregoing provisions of Section 4.02(b) to fund Accordion Capital Contributions shall become obligations of both the Crestwood Member and the Holdings Member, and such obligations shall be performed pro rata in proportion to each of such Member’s respective ownership of outstanding Series A Preferred Units, and the Maximum Holdings Member Accordion Amount shall be reduced proportionately to adjust for the percentage of Series A Preferred Units no longer held by the Holdings Member. Immediately upon the receipt of any Accordion Capital Contribution by the Crestwood Member, except as provided in the penultimate sentence of Section 4.02(b)(i), the Company shall issue to the Crestwood Member a number of Series A-2 Preferred Units equal to the amount of such Accordion Capital Contribution made by the Crestwood Member divided by the Series A-2 Preferred Unit Price.

-32-

(iv)Before a Conversion, in connection with any capital requirements of the Company, other than an Agreed Midstream Project or Crestwood Scheduled Project, the Managing Member shall fund the amount of such capital requirement (A) out of the operating cash flows of the Company (but only to the extent of Available Cash) and/or (B) by drawing on a credit facility approved in accordance with Section 6.02, as applicable, except to the extent that the Managing Member has determined that it is commercially reasonable to fund all or a portion of such capital requirements with Capital Contributions from the Crestwood Member. To the extent that the Managing Member has determined to fund any such capital requirements pursuant to clauses (A) or (B) above in this Section 4.02(b)(iv), and such funding sources are not sufficient to satisfy the full capital requirement, the remaining amount of such capital requirement shall be made by the Crestwood Member in exchange for a number of Common Units equal to the amount of such contribution divided by the Common Unit Price.

(c)Post-Conversion Capital Call For Capital Contribution. Without limiting the obligations of the Members pursuant to the penultimate sentence of Section 4.02(b)(i), subject to Section 6.02 and Section 6.03, at any time after a Conversion, the Managing Member may request that the Members make additional Capital Contributions by issuing a notice to the Members in accordance with Section 4.02(d). Each Member shall have the right, but not the obligation, to elect to make Capital Contributions pursuant to such a notice. Within 30 days after the receipt of such notice, each Member shall notify the Managing Member whether it elects to fund its pro rata portion of the requested Capital Contribution. If any Member does not notify the Managing Member of such election within such 30 days, then such Member will be deemed to have elected not to fund its pro rata portion, and the Member that has elected to fund will have the option to fund the entire Capital Contribution amount and/or may allow another Person to make all or any portion of the Capital Contribution.

(d)Capital Call Notices. Prior to any request for Capital Contributions, the Managing Member shall send each Member a written notice setting forth (i) in reasonable detail the Agreed Midstream Project or other project giving rise to such request for Capital Contributions, (ii) the amount of such Capital Contribution requested (and, if applicable, the amount of any future anticipated requests for Capital Contributions in connection with such Agreed Midstream Project or other project), (iii) the portion of such requested Capital Contribution that each Member is obligated or requested to contribute, (iv) if after Conversion, the Fair Market Value of the Common Units to be issued in exchange for such Capital Contributions and (v) the date on which such Capital Contributions must occur, which shall in each case be no less than 30 days after the date of such notice.

4.03Funding Defaults.

(a)Failure of the Crestwood Member to Make a Crestwood Additional Capital Contribution. If, prior to a Conversion, the Crestwood Member fails to fund 100% of any Crestwood Additional Capital Contribution when due and fails to cure such default within three Business Days after such due date (any such failure, a “Deficiency Event”), then the Company shall promptly, but in no event later than three Business Days after the due date for such Crestwood Additional Capital

-33-

Contribution, provide written notice of such failure to the Holdings Member, and the Holdings Member shall have the option, in its sole discretion and as its sole and exclusive remedy hereunder, to fund the amount of such deficiency (any such amount funded by the Holdings Member, a “Deficiency Contribution”). Immediately upon receipt of any Deficiency Contribution by the Company, the Company shall issue to the Holdings Member a number of Series B Preferred Units equal to the amount of such Deficiency Contribution divided by the Series B Preferred Unit Price. A Deficiency Event shall not relieve the Crestwood Member of its obligation to make any Crestwood Additional Capital Contributions subsequent thereto.

(b)Failure of Holdings Member to Make an Accordion Capital Contribution. If, prior to a Conversion, the Holdings Member fails to fund 100% of any Accordion Capital Contribution when due and fails to cure such default within three Business Days after such due date (any such failure, a “Holdings Member Default”), then the Company shall promptly, but in no event later than three Business Days after the due date for such Accordion Capital Contribution, provide written notice of such failure to the Crestwood Member, and the Crestwood Member shall have the option, in its sole discretion and as its sole and exclusive remedy hereunder (any such amount funded by the Crestwood Member, a “Default Contribution”). Immediately upon receipt of any Default Contribution by the Company, the Company shall issue to the Crestwood Member a number of Series C Preferred Units equal to the amount of such Default Contribution divided by the Series C Unit Price. A Holdings Member Default shall not relieve the Holdings Member of its obligation to make any Accordion Capital Contributions subsequent thereto.

(c)Failure of a Member to Fund a Post-Conversion Capital Contribution.

(i)If, following a Conversion, either Member elects to fund in response to a request for Capital Contributions (or is required to fund pursuant to the penultimate sentence of Section 4.02(b)(i)) but fails to fund such amount when due, and in either case, fails to cure such default within three Business Days after such due date (such Member, a “Non-Funding Member,” and any such failure, a “Post-Conversion Default”), then the Company shall promptly, but in no event later than three Business Days after the due date for such Capital Contribution, provide written notice of such failure to the non-defaulting Member, and such non-defaulting Member shall have the option, in its sole discretion, to fund the amount of such Post-Conversion Default (any such amount funded by such Member in accordance with this Section 4.03(c)(i), a “Post-Conversion Default Contribution”). Any Member that funds a Post-Conversion Default Contribution in accordance with this Section 4.03(c) is referred to herein as a “Funding Member” and shall be entitled to certain amounts as set forth in this Section 4.03(c).

(ii)If a Post-Conversion Default Contribution is made by the Funding Member, and the Total Amount in Default with respect thereto is paid by or on behalf of a Non-Funding Member to the Company within 30 days after the applicable Post-Conversion Default (a “Payment Cure”), then the Company shall pay to the Funding Member, within five Business Days of receipt, an amount equal to the Total Amount in Default less any distributions already paid to the Funding Member pursuant to Section 4.03(c)(iii).

-34-

(iii)From and after a Post-Conversion Default, the applicable Non-Funding Member’s right to receive distributions pursuant to this Agreement shall be suspended and paid to the Funding Member or retained by the Company, as applicable, until the earlier of a Payment Cure and the time at which such aggregate distributions withheld from the Non-Funding Member (together with any additional contributions made by the Non-Funding Member pursuant to the following sentence) equal either (x) if a Funding Member funded the Post-Conversion Default Contribution, 250% of the Total Amount in Default or (y) if no Funding Member funded the Post-Conversion Default Contribution, the amount of the Post-Conversion Default Contribution plus interest at a 10% interest rate on the sum of the foregoing amounts in this clause (y). Notwithstanding the foregoing, a Non-Funding Member shall have the right, at any time prior to the suspension of distributions referenced above terminating, to accelerate the date on which such suspension terminates by paying to the Company such amounts as are necessary to achieve the threshold identified in foregoing clause (x) or (y), as applicable, and if it does so, then such thresholds will be deemed satisfied and such funds shall be paid to the Funding Member or retained by the Company, as applicable, and then such suspension of distributions shall immediately cease.

(iv)A Post-Conversion Default shall not relieve the Non-Funding Member of its obligation to fund its pro rata portion of any other Capital Contributions that it elected or is required to fund.

4.04Withdrawal or Return of Capital. Except as provided in this Agreement, including Sections 4.06 and 5.01, no Member is entitled to the return of or has the right to withdraw any part of its Capital Contribution from the Company prior to its liquidation and termination pursuant to Article X hereof. No Member is entitled to be paid interest in respect of either its Capital Account or its Capital Contributions. Any unrepaid Capital Contribution is not a liability of the Company or of the other Members. A Member is not required to contribute or to lend any cash or property to the Company to enable the Company to return any other Member’s Capital Contributions.

4.05Further Contributions.

(a)If the Company becomes obligated to make an indemnification payment (or to expend funds, or to make payments to third parties) pursuant to either of the Subscription Agreements with respect to Losses (as defined in each of the Subscription Agreements) and it does not at such time have sufficient Available Cash after payment of all amounts otherwise due or owing at such time, then the Crestwood Member shall promptly make a contribution of immediately available funds into the Company in an amount sufficient to permit the Company promptly to make such indemnification payment (or to pay such expense, or to pay any such third party) in full, and the Company shall promptly make such indemnification payment (or pay such expense, or pay any such third party) upon receipt; provided, however, that, following a Conversion, indemnification payments (as well as payments of expenses and payments to third parties) pursuant to either of the Subscription Agreements with respect to Losses (as defined in each of the Subscription Agreements) shall not be made by the Company from Available Cash but instead the Crestwood Member shall promptly make a contribution of immediately available funds into the Company in an amount sufficient to make the full amount of such indemnification or other payments in full from such

-35-

contributed funds. Notwithstanding anything else in this Agreement to the contrary, (i) any such indemnification payment made by the Company from Available Cash (or any funds expended by the Company, or paid by the Company to a third party from a source other than a contribution by the Crestwood Member to the Company pursuant to this Section 4.05(a)) with respect to Losses (as defined in each of the Subscription Agreements) giving rise to such indemnification obligation (an “Indemnification Payment”) shall be deemed (x) to the extent that an Indemnification Payment is made on account of Losses (as defined in the Series A-2 Subscription Agreement) under the Series A-2 Subscription Agreement, a distribution to the Crestwood Member for purposes of the definition of Series A-2 Adjusted Capex Amount and (y) to the extent that an Indemnification Payment is made on account of Losses (as defined in the Series A-3 Subscription Agreement) under the Series A-3 Subscription Agreement, a distribution to the Crestwood Member for purposes of the definition of Series A-3 Adjusted Capex Amount and shall not be a distribution to the Holdings Member for any purpose under this Agreement and (ii) any contribution by the Crestwood Member to the Company to permit the Company to make such an indemnification payment (or to fund such an expense, or such a payment to a third party) with respect to Losses (as defined in each of the Subscription Agreements) shall not be a Capital Contribution for the purposes of the definition of Series A-2 Adjusted Capex Amount, Series A-3 Adjusted Capex Amount or for the purposes of Section 5.01(b)(ii)(A). Without any effect on the foregoing, if the Crestwood Member makes any contribution to the Company pursuant to this Section 4.05(a), then the Company shall (I) issue to the Crestwood Member a number of Common Units equal to the quotient obtained by dividing the amount of such contribution by either (x) the Common Unit Price, if such contribution occurs prior to a Conversion or (y) the Fair Market Value per Common Unit, if such contribution occurs following a Conversion and (II) if such contribution by the Crestwood Member occurs following a Conversion, issue to the Holdings Member a number of Common Units equal to the product of the number of Common Units issuable to the Crestwood Member pursuant to the foregoing clause (I)(y)multiplied by a fraction, the numerator of which is the number of Common Units held by the Holdings Member as of immediately prior to such contribution and the denominator of which is the number of Common Units held by the Crestwood Member as of immediately prior to such contribution. For the avoidance of doubt, the issuance of Common Units as contemplated by the preceding sentence shall not be a Capital Contribution for purposes of, and shall not be subject to, Section 4.02 or Section 4.03, and neither Member shall be required to make any contributions with respect thereto (other than the obligation of the Crestwood Member expressly referenced in this Section 4.05).

(b)Except as otherwise specifically provided in this Agreement, no further Capital Contributions will be required from any Member without such Member’s prior written consent, and no Member shall have any obligation to restore any deficit balance in such Member’s Capital Account.

4.06Redemption of Preferred Units.

(a)Deficiency Preferred Units. Following the issuance of any Deficiency Preferred Units and until the earlier of the date that such Deficiency Preferred Units have been redeemed in full in accordance with this Agreement, 100% of all Adjusted Available Cash on hand and thereafter received by the Company shall immediately be paid over to the Holdings Member and the Crestwood Member, pro rata in accordance with their respective holdings of Deficiency

-36-

Preferred Units, to redeem all outstanding Deficiency Preferred Units; provided that (i) a Series B Preferred Unit will be redeemed pursuant to the foregoing clause upon the Holdings Member’s receipt of cash in respect of such Series B Preferred Unit in the amount required to provide the Holdings Member an IRR equal to 20% with respect to such Series B Preferred Unit and (ii) a Series C Preferred Unit will be redeemed pursuant to the foregoing clause upon the Crestwood Member’s receipt of cash in respect of such Series C Preferred Unit in the amount required to provide the Crestwood Member an IRR equal to 20% with respect to such Series C Preferred Unit. Without limiting the generality of the foregoing, the right of the Holdings Member and the Crestwood Member to have any Deficiency Preferred Units redeemed pursuant to this Section 4.06(a) will be senior in right of payment to all distributions to Members or redemptions of Units by the Company.

(b)Crestwood Change of Control. In the event of a Crestwood Change of Control, the Crestwood Member shall use commercially reasonable efforts to provide the Holdings Member with no less than 30 days advance written notice of such Crestwood Change of Control, and within five Business Days following such Crestwood Change of Control, if any, the Holdings Member may elect by written notice to the Crestwood Member (the “Change of Control Redemption Notice”) to require the Company to redeem from the Holdings Member all then-outstanding Series A Preferred Units and Series B Preferred Units. Within five Business Days following delivery of the Change of Control Redemption Notice, the Crestwood Member shall deliver written notice to the Holdings Member (the “Consideration Election Notice”) indicating whether (i) the Company has elected to redeem the then-outstanding Series A Preferred Units and Series B Preferred Units for cash, (ii) in lieu of such redemption, the Crestwood Member will acquire from the Holdings Member the then-outstanding Series A Preferred Units and Series B Preferred Units through the issuance to the Holdings Member or its designee as consideration a number of CEQP Units, valued at the CEQP Unit Price calculated as of the date of such Crestwood Change of Control, or (iii) it elects to effect a combination of the actions described in clauses (i) and (ii) above, in any case, in an amount per Series A Preferred Unit equal to the Change of Control Redemption Price and an amount per Series B Preferred Unit equal to the Change of Control Redemption Price; provided, however, that (A) the options set forth in the foregoing clauses (ii) and (iii) shall not be available at any time at which an RRA Suspension Right would be, or would reasonably likely to be, exercisable by CEQP pursuant to the Registration Rights Agreement if the Holdings Member were to exercise a demand registration right pursuant to Section 2.03 of the Registration Rights Agreement immediately following the issuance of CEQP Units to the Holdings Member, (B) the number of CEQP Units issued pursuant to this Section 4.06(b) shall not exceed the Maximum Redemption Units (it being acknowledged and agreed that the issuance of the Maximum Redemption Units, if applicable, shall redeem in full all of the then-outstanding Series A Preferred Units and Series B Preferred Units and no further cash or other consideration shall be required to be paid in connection therewith) and (C) CEQP shall comply with its obligations under the Registration Rights Agreement with respect to such CEQP Units so issued. The closing of any redemption or acquisition pursuant to this Section 4.06(b) shall occur no later than the tenth Business Day following the delivery of the Change of Control Redemption Notice; provided, however, that in the event that the Crestwood Member fails to deliver a Consideration Election Notice prior to the fifth Business Day following the delivery of the Change of Control Redemption Notice, the Company shall be deemed to have elected to redeem the then-outstanding Series A Preferred Units and Series B Preferred Units

-37-

pursuant to this Section 4.06(b) in cash and the closing for such redemption shall occur no later than the tenth Business Day following the delivery of the Change of Control Redemption Notice.

(c)Company Change of Control. In the event of a Company Change of Control, the Crestwood Member shall use commercially reasonably efforts to provide the Holdings Member with no less than 30 days advance written notice of such Company Change of Control, and within five Business Days following such Company Change of Control, if any, the Holdings Member may elect by delivery of a Change of Control Redemption Notice to require the Company to redeem from the Holdings Member all then-outstanding Series A Preferred Units and Series B Preferred Units. Within five Business Days following delivery of the Change of Control Redemption Notice, the Crestwood Member shall deliver a Consideration Election Notice to the Holdings Member indicating whether (i) the Company has elected to redeem the then-outstanding Series A Preferred Units and Series B Preferred Units for cash, (ii) in lieu of such redemption, the Crestwood Member will acquire from the Holdings Member the then-outstanding Series A Preferred Units and Series B Preferred Units through the issuance to the Holdings Member or its designee as consideration a number of CEQP Units, valued at the CEQP Unit Price calculated as of the day prior to such redemption, (iii) it elects to effect a combination of the actions described in clauses (i) and (ii) above, in any case, in an amount per Series A Preferred Unit equal to the Change of Control Redemption Price and an amount per Series B Preferred Unit equal to the Change of Control Redemption Price or (iv) the Company has elected to redeem the then-outstanding Series A Preferred Units and Series B Preferred Units using the cash proceeds from a sale of some or all of the operating assets of the Company, including interests in any of the Company’s Subsidiaries (an “Asset Sale”) and to the extent the cash proceeds from an Asset Sale are less than the Change of Control Redemption Price payable to Holdings Member, the issuance to the Holdings Member or its designee as consideration a number of CEQP Units, valued at the CEQP Unit Price calculated as of the day prior to such redemption; provided, however, that (A) the options set forth in the foregoing clauses (ii) and (iii) shall not be available if any of the CEQP Unit Issuance Limitations would be triggered in such proposed issuance, (B) the number of CEQP Units issued pursuant to this Section 4.06(c) shall not exceed the Maximum Redemption Units (it being acknowledged and agreed that the issuance of the Maximum Redemption Units, if applicable, shall redeem in full all of the then-outstanding Series A Preferred Units and Series B Preferred Units and no further cash or other consideration shall be required to be paid in connection therewith), and (C) CEQP shall comply with its obligations under the Registration Rights Agreement with respect to such CEQP Units so issued. The closing of any redemption or acquisition pursuant to this Section 4.06(c) shall occur no later than the later to occur of (x) the tenth Business Day following delivery of the Change of Control Redemption Notice and (y) the consummation of an Asset Sale, if applicable; provided, however, that in the event that the Crestwood Member fails to deliver a Consideration Election Notice prior to the fifth Business Day following the delivery of the Change of Control Redemption Notice, the Company shall be deemed to have elected the payment option described above in clause (iv).

(d)Crestwood Option for Redemption – Full Redemption.

In connection with any redemption or acquisition of less than all of the then-outstanding Series A Preferred Units or Series B Preferred Units pursuant to this Section 4.06, such redemption or acquisition shall be effected in a manner such that the earliest-issued, then-outstanding Series A Preferred Units or Series B Preferred Units, as applicable, are redeemed prior to the redemption of any later-issued Series A Preferred Units or Series B Preferred Units.

The CEQP Guaranty is absolute, continuing and independent of, and in addition to, any and all rights and remedies of the Holdings Member under this Agreement, and shall not in any way be discharged, impaired or otherwise affected by any of the following, each of which is hereby waived by CEQP: (a) any release or waiver of, or delay in, the enforcement of any rights of the Holdings Member, or (b) any requirements for promptness, diligence, notice of acceptance, presentment, demand for performance, notice of non-performance, default, acceleration, protest or dishonor or any other notice or similar requirement.

4.07Conversion of Preferred Units.

(a)Conditional Conversion Option.

(i)At any time after December 31, 2020 but prior to December 31, 2023, the Holdings Member may elect by written notice to the Crestwood Member (the “Initial Period Conversion Notice”) to cause the Company to convert all, but not less than all, of the then-outstanding Series A Preferred Units into an aggregate number of Common Units

-42-

that, following such Conversion, shall equal the product of (x) the Aggregate Conversion Ratio multiplied by (y) the aggregate number of outstanding Common Units as of immediately following such Conversion (the “Initial Period Conversion”), which Common Units shall be issued to the Holdings Member (or, if the Crestwood Member acquired any Series A Preferred Units pursuant to Section 3.04, then to the Holdings Member and the Crestwood Member in proportion to their respective ownership of all Series A Preferred Units); provided, however, that the Holdings Member’s right to effect a Conversion shall be limited solely to the extent required to be limited by applicable law.

(ii)At any time after December 31, 2023, the Holdings Member may elect by written notice to the Crestwood Member (the “Secondary Period Conversion Notice”) to cause the Company to (A) convert all, but not less than all, of the then-outstanding Series A Preferred Units into an aggregate number of Common Units that, following such Conversion, shall equal the product of (x) the Aggregate Conversion Ratio multiplied by (y) the aggregate number of outstanding Common Units as of immediately following such Conversion (the “Secondary Period Full Conversion”), (B) convert all, but not less than all, of the then-outstanding Series A-2 Preferred Units into an aggregate number of Common Units that, following such Conversion, shall equal the product of (x) the A-2 Conversion Ratio multiplied by (y) the aggregate number of outstanding Common Units as of immediately following such Conversion (the “Secondary Period A-2 Conversion”), or (C) convert all, but not less than all, of the then-outstanding Series A-3 Preferred Units into an aggregate number of Common Units that, following such Conversion, shall equal the product of (x) the A-3 Conversion Ratio multiplied by (y) the aggregate number of outstanding Common Units as of immediately following such Conversion (the “Secondary Period A-3 Conversion”), in each case which Common Units shall be issued to the Holdings Member (or, if the Crestwood Member acquired any Series A Preferred Units pursuant to Section 3.04, then to the Holdings Member and the Crestwood Member in proportion to their respective ownership of all Series A Preferred Units); provided, however, that the Holdings Member’s right to effect a Conversion shall be limited solely to the extent required to be limited by applicable law. In the event that the Secondary Period Conversion Notice elects either a Secondary Period A-2 Conversion or a Secondary Period A-3 Conversion, the other series of Series A Preferred Units not being converted shall be redeemed in accordance with Section 4.06(f) and the delivery of the Secondary Period Conversion Notice shall be deemed to be a Holdings Member Redemption Notice with respect to such other series of Series A Preferred Units.

(b)Effectiveness of Conversion; Rights of Holdings Member Upon Conversion. A Conversion shall be effective immediately, and without any payment of consideration or further action by the Company, or the Members, upon the delivery by the Holdings Member of a Conversion Notice to the Crestwood Member. Upon a Conversion, the rights of the Holdings Member (and if applicable, the Crestwood Member) in its capacity as a holder of Series A Preferred Units or Series B Preferred Units shall cease with respect to such Units, including any rights under this Agreement with respect to such Units.

-43-

(c)Reimbursement Obligation Following Conversion. No later than 10 Business Days following a Conversion, the Crestwood Member shall deliver a written notice to the Holdings Member setting forth the Applicable Adjusted Capex Amount and wire transfer instructions for the account to which the Holdings Member should deliver the funds required (if the Applicable Adjusted Capex Amount is positive) pursuant to this Section 4.07(c).  No later than 10 Business Days following the receipt of such notice, (I) if the Applicable Adjusted Capex Amount is positive, the Holdings Member shall deliver to the Crestwood Member a written notice agreeing to one of the following three options: (i) to pay to the Crestwood Member the Applicable Adjusted Capex Amount in immediately available funds to an account designated by the Crestwood Member, (ii) having the Company reduce the number of Common Units held by the Holdings Member following the Conversion by a number of Common Units equal to the quotient of (A) the Applicable Adjusted Capex Amount divided by (B) the Common Unit Price or (iii) electing to pay a portion of the Applicable Adjusted Capex Amount and instructing the Company to reduce the number of Common Units held by the Holdings Member following the Conversion by a number of Common Units equal to the quotient of (A) the balance of the Applicable Adjusted Capex Amount divided by (B) the Common Unit Price, or (II) if the Applicable Adjusted Capex Amount is negative, Holdings Member shall deliver to Crestwood Member wire transfer instructions for the account to which the Crestwood Member should deliver the required funds and Crestwood Member shall pay to the Holdings Member the Applicable Adjusted Capex Amount in immediately available funds to such account designated by the Holdings Member no later than 10 Business Days following receipt of the wire instructions. If the Holdings Member elects options (i) or (iii), then the Holdings Member shall deliver the Applicable Adjusted Capex Amount (or in the case of option (iii) the reduced amount thereof) to the Crestwood Member no later than 10 Business Days following the delivery of such notice to the Crestwood Member.  If the Holdings Member elects options (ii) or (iii), then, without any further action by the Company, the board or the Members, the number of Common Units held by the Holdings Member shall automatically be reduced as instructed, effective upon the Conversion. If the Holdings Member fails to deliver a written notice within such 10 Business Day period or otherwise fails to fund the Applicable Adjusted Capex Amount, the Holdings Member shall be deemed to have elected option (ii), and the number of Common Units held by the Holdings Member shall be reduced in accordance with the provisions thereof.

(d)Evaluation of G&A Services Fee. Following a Conversion, the Crestwood Member and the Holdings Member shall (i) evaluate the G&A Services Fee set forth in the Operating Agreement and (ii) use commercially reasonable efforts to agree on an appropriate replacement G&A Services Fee to reflect changes in the scope of G&A services provided by the Operator (as defined in the Operating Agreement).

(b)Distributions of Available Cash.

(i)Subject to Section 5.01(b)(ii), the Managing Member shall cause the Company to make a distribution of 100% of all Available Cash in respect of a particular Fiscal Quarter to the Common Members in respect of the Common Units outstanding as of the end of such Fiscal Quarter (it being understood that, as of the Effective Date, the Crestwood Member shall be the only Common Member), provided that, if such distribution

-45-

is prior to a Conversion, immediately prior to making such distribution (A) the Company has distributed any Series A Quarterly Distribution required with respect to such Fiscal Quarter, (B) there are no Series A Quarterly Distributions required to have been distributed pursuant to Section 5.01(a) with respect to any concluded Fiscal Quarter that remain unpaid, (C) no Series B Preferred Units are outstanding and (D) the Managing Member and the Company have each provided the Holdings Member with a written certificate in the form attached as Exhibit B at least three Business Days prior to making such distribution specifying that as of such time, no Material Adverse Change has occurred, nor will any Material Adverse Change occur as a result of the Company’s making such distribution.

(ii)If a Conversion has not yet occurred, in addition to fulfilling the conditions set forth in the proviso of Section 5.01(b)(i), at any time after December 31, 2023, the Managing Member shall cause the Company to make a distribution of 100% of all Available Cash in respect of a particular Fiscal Quarter as follows:

(A)First, pro rata to the Holdings Member and the Crestwood Member in accordance with their then-current respective aggregate Capital Contributions (but disregarding any contributions as contemplated by Section 4.05) as of the making of such distribution; provided that, for the purpose of this Section 5.01(b)(ii), (1) “Available Cash” shall include the aggregate amount of the Series A Quarterly Distribution required to be distributed in respect of the Series A Preferred Units with respect to such Fiscal Quarter and (2) the amount of Available Cash deemed to have been distributed to the Holdings Member for purposes of this Section 5.01(b)(ii) shall include the amount of any such Series A Quarterly Distribution required to be distributed to the Holdings Member with respect to such Fiscal Quarter; and

(B)Second, upon the receipt by the Holdings Member pursuant to Section 5.01(b)(ii)(A) of an amount of distributions equal to (1) in respect of each outstanding Series A-2 Preferred Unit equal to (x) the amount required to provide to the Holdings Member an IRR equal to 10% on each such outstanding Series A-2 Preferred Unit, less (y) the Series A-2 Preferred Unit Price, and (2) in respect of each outstanding Series A-3 Preferred Unit equal to (x) the amount required to provide to the Holdings Member an IRR equal to 10% on each such outstanding Series A-3 Preferred Unit, less (y) the Series A-3 Preferred Unit Price, then 100% to the Crestwood Member in respect of the Common Units.

(c)Withholding. Notwithstanding anything to the contrary herein, the Managing Member, in connection with and subject to the consent of the Holdings Member (such consent not to be unreasonably withheld, conditioned or delayed), shall determine the amounts of any required tax withholdings. In connection therewith, the Managing Member may retain or withhold amounts (including any amounts imposed pursuant to Section 6225 of the Code) and make tax payments, including interest and penalties thereon, on behalf of or with respect to any Member (“Tax Advances”). All Tax Advances made on behalf of a Member shall, at the option of the Managing Member, (i) be promptly paid to the Company by the Member on whose behalf such Tax Advances

-46-

were made or (ii) be repaid by reducing the amount of the current or next succeeding distribution or distributions which would otherwise have been made to such Member or, if such distributions are not sufficient for that purpose, by so reducing the proceeds of liquidation of the Company otherwise payable to such Member. Whenever the Managing Member selects option (ii) pursuant to the preceding sentence for repayment of a Tax Advance by a Member, for all other purposes of this Agreement, such Member shall be treated as having received all distributions unreduced by the amount of such Tax Advance. For the avoidance of doubt, notwithstanding anything to the contrary in this Agreement, the liabilities and obligations of each Member under this Section 5.01(c) shall survive any deemed Transfer of an interest in the Company by such Member or such Member ceasing to be a Member under this Agreement.

(d)Distributions in Error. Any distributions pursuant to this Section 5.01made in error or in violation of Section 18-607(a) of the Act, will, upon good faith demand by the Managing Member (or the Holdings Member, if such distribution in error was received by the Managing Member), be returned to the Company.

5.02Allocations.

(a)In General. Except as provided in Section 5.02(b), for purposes of maintaining Capital Accounts, items of Company income, gain, loss, deduction and credit for each applicable accounting period (taking into account, for this purpose, any positive adjustments to the Book Values of Company assets in the same manner as if such adjustments were items of income or gain and any negative adjustments to the Book Values of Company assets in the same manner as if such adjustments were items of deduction or loss) shall be allocated among the Members in a manner that will, as nearly as possible, cause the Capital Account balance of each Member at the end of such period to equal the amount (which may be negative) determined for such Member by subtracting item (ii) from item (i) below:

(i)the amount that would be distributed to such Member (other than any amounts treated as a guaranteed payment under Section 707(c) of the Code) if: (A) all Company assets were sold for cash equal to their Book Values; (B) all Company obligations were satisfied in cash according to their terms (limited, with respect to each Nonrecourse Liability or Member Nonrecourse Debt, to the Book Values of the assets securing or subject to such liability); and (C) the net proceeds thereof (after satisfaction of such liabilities) were distributed in full pursuant to Section 10.02(c) (ignoring, for this purpose, Section 10.02(c)(ii)(B)(1), and applying Section 10.02(c)(ii)(B)(2) as if it applied at any time prior to the commencement of the Holdings Member Option Period); over

(ii)the sum of: (A) such Member’s share of the Company Minimum Gain determined pursuant to Treasury Regulations Section 1.704-2(g) computed immediately prior to the hypothetical sale described above, (B) such Member’s share of Member Minimum Gain determined pursuant to Treasury Regulations Section 1.704-2(i)(5), computed immediately prior to the hypothetical sale described above and (C) the amount, if any, that such Member is obligated to contribute to the capital of the Company computed after the hypothetical events described in Section 5.02(a)(i) above;

-47-

provided, however, notwithstanding anything to the contrary in this Section 5.02(a), the amount of items of Company deduction and loss allocated to any Member pursuant to this Section 5.02(a) shall not exceed the maximum amount of such items that can be so allocated without causing such Member to have a deficit balance in its Adjusted Capital Account at the end of any Tax Year or other applicable accounting period. Items of deduction and loss in excess of such limitation shall be allocated to the Members who do not have deficit balances in their Adjusted Capital Accounts, pro rata, in proportion to the amounts that may be so allocated to them without causing them to have such deficit balances.

(b)Regulatory Allocations. Notwithstanding the foregoing provisions of Section 5.02(a), the following special allocations will be made in the following order of priority:

(i)Minimum Gain Chargeback. If there is a net decrease in Company Minimum Gain during an applicable accounting period, then each Member will be allocated items of Company income and gain for such period (and, if necessary, for subsequent periods) in an amount equal to such Member’s share of the net decrease in Company Minimum Gain, determined in accordance with Treasury Regulations Section 1.704-2(g)(2). This Section 5.02(b)(i) is intended to comply with the minimum gain chargeback requirement of Treasury Regulations Section 1.704-2(f) and will be interpreted consistently therewith.

(ii)Member Minimum Gain Chargeback. If there is a net decrease in Member Minimum Gain attributable to a Member Nonrecourse Debt during any applicable accounting period, each Member who has a share of the Member Minimum Gain attributable to such Member Nonrecourse Debt, determined in accordance with Treasury Regulations Section 1.704-2(i)(5) will be specially allocated items of Company income and gain for such period (and, if necessary, subsequent periods) in an amount equal to such Member’s share of the net decrease in Member Minimum Gain attributable to such Member Nonrecourse Debt, determined in a manner consistent with the provisions of Treasury Regulations Section 1.704-2(g)(2) and (j)(2)(ii). This Section 5.02(b)(ii) is intended to comply with the partner nonrecourse debt minimum gain chargeback requirement of Treasury Regulations Section 1.704-2(i)(4) and will be interpreted consistently therewith.

(iii)Qualified Income Offset. If any Member unexpectedly receives an adjustment, allocation, or distribution of the type contemplated by Treasury Regulations Sections 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of income and gain will be allocated to such Member in an amount and manner sufficient to eliminate any resulting deficit balance in such Member’s Adjusted Capital Account as quickly as possible, provided that an allocation pursuant to this Section 5.02(b)(iii) shall be made if and only to the extent that such Member would have an Adjusted Capital Account deficit after all other allocations provided for in this Article V have been tentatively made as if this Section 5.02(b)(iii) were not in this Agreement. It is intended that this Section 5.02(b)(iii) qualify and be construed as a “qualified income offset” within the meaning of Treasury Regulations Section 1.704-1(b)(2)(ii)(d).

(iv)Certain Additional Adjustments. To the extent that an adjustment to the adjusted tax basis of any Company asset pursuant to Code Section 734(b) or Code Section

743(b) is required, pursuant to Treasury Regulations Section 1.704‑1(b)(2)(iv)(m)(2) or Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(4), to be taken into account in determining Capital Accounts as the result of a distribution to a Member in complete liquidation of its Interest, the amount of such adjustment to the Capital Accounts will be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis), and such gain or loss will be specially allocated to the Members in accordance with their Interests in the Company in the event that Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(2) applies, or to the Members to whom such distribution was made in the event that Treasury Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies.

(v)Nonrecourse Deductions. The Nonrecourse Deductions for each Tax Year will be allocated to holders of Common Units in proportion to the relative number of Common Units held.

(vi)Member Nonrecourse Deductions. Member Nonrecourse Deductions will be allocated to the Members that bear the economic risk of loss (within the meaning of Treasury Regulations Section 1.752-2) for the Member Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable.

(vii)Curative Allocations. The allocations contained in the foregoing provisions of this Section 5.02(b), and any allocations required following the proviso in Section 5.02(a), are intended to comply with certain requirements of the Treasury Regulations promulgated under Code Section 704. It is the intent of the Members and the Company that, to the extent possible, all such allocations shall be offset either with other such allocations or with special allocations of other items of income, gain, loss or deduction pursuant to this Section 5.02(b)(vii), so that after such offsetting allocations are made, each Member’s Capital Account balance is, to the extent possible, equal to the Capital Account balance such Member would have had if no such allocations had been made and all items were allocated pursuant to Section 5.02(a) (not including the allocations required following the proviso in Section 5.02(a)).

(viii)Noncompensatory Option. Items of income, gain, loss or deduction resulting from a restatement of the Book Values of Company assets pursuant to clause (b)(iii) of the definition of Book Value shall be allocated among the Members in the manner described in Treasury Regulations Section 1.704-1(b)(2)(iv)(s)(2).

(c)Tax Allocations.

(i)Except as provided in Section 5.02(c)(ii) hereof, to the maximum extent possible, for U.S. federal income tax purposes (and for purposes of any state or local income or franchise tax that follows the federal treatment), each item of Company income, gain, loss or deduction will be allocated among the Members in the same manner as the correlative item of income, gain, loss or deduction is allocated for purposes of maintaining Capital Accounts pursuant to this Article V.

-49-

(ii)Tax items with respect to any Company asset that has a Book Value that differs from its adjusted tax basis will be allocated among the Members for federal income tax purposes in a manner consistent with the Treasury Regulations promulgated under Code Sections 704(b) and 704(c) so as to take into account such difference utilizing the remedial allocation method under Treasury Regulations Section 1.704-3(d).

(d)Other Provisions. The Members, their respective Affiliates and Permitted Transferees, and the Company, intend and agree to treat the Preferred Units as equity interests in the Company for U.S. federal income tax purposes, and the Company as a partnership, for U.S. federal income tax purposes, except as otherwise required by applicable law following a final “determination” under Code Section 1313 or as otherwise agreed by all of the Members (including, for the avoidance of doubt, the Holdings Member to the extent such treatment is relevant to the treatment of the Company or any holder of a Preferred Unit for any Tax Year or portion thereof in which the Holdings Member, any of its Affiliates or Permitted Transferees, is or was a Member). In the event that it is determined upon audit by the Internal Revenue Service that the Company, the Crestwood Member, or any of its Affiliates or Permitted Transferees, is required to treat the rights and obligations represented by the Preferred Units as indebtedness for U.S. federal income tax purposes, the Members, their respective Affiliates and Permitted Transferees, and the Company agree to revise the provisions of this Agreement and take such other action as may be reasonably requested by either Member to minimize the effect of such treatment on all of the Members.

(e)Compliance with Subchapter K. Notwithstanding anything to the contrary in this Agreement, in the discretion of the Managing Member, with the consent of the Holdings Member, the Company may diverge from the allocations described herein as may be necessary or appropriate to comply with the provisions of subchapter K of the Code and the Treasury Regulations promulgated thereunder.

11.11Counterparts. This Agreement may be executed in any number of counterparts with the same effect as if all signatories had signed the same document. All counterparts will be construed together and constitute the same instrument.

11.12Electronic Transmissions. Each of the Parties agrees that (a) any signed consent or signed document transmitted by electronic transmission shall be treated in all manner and respects as an original written document, (b) any such consent or document shall be considered to have the same binding and legal effect as an original document and (c) at the request of any Party, any such consent or document shall be re-delivered or re-executed, as appropriate, by the relevant Party or Parties in its original form.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

Our consolidated financial statements are prepared in accordance with Generally Accepted Accounting Principles (GAAP) and include the accounts of all consolidated subsidiaries after the elimination of all intercompany accounts and transactions. In management’s opinion, all necessary adjustments to fairly present our results of operations, financial position and cash flows for the periods presented have been made and all such adjustments are of a normal and recurring nature. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with GAAP have been omitted pursuant to the rules and regulations of the SEC.

Significant Accounting Policies

Effective January 1, 2019, we adopted the following accounting standard. There were no other material changes in our significant accounting policies from those described in our 2018 Annual Report on Form10-K.

Leases

We maintain leases in the ordinary course of our business activities. Our leases include those for the office buildings, crude oil railroad cars, certain vehicles and other operating facilities and equipment leases. We also sublease certain of our crude oil railroad cars and trucks to a third party. We do not have any material leases where we are considered to be the lessor. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Prior to January 1, 2019, we classified our leases as either capital or operating leases under Accounting Standards Codification (ASC) Topic 840, Leases (Topic 840). We recognized assets (included in property, plant and equipment) and liabilities (included in accrued expenses and other liabilities and other long-term liabilities) related to our capital leases on our consolidated balance sheets. We also recognized depreciation expense and interest expense related to our capital leases on our consolidated statements of operations. The majority of our lease arrangements were classified as operating leases, under which we did not recognize assets or liabilities on our consolidated balance sheets, but rather recognized lease payments on our consolidated statements of operations as either costs of product/services sold or operations and maintenance expense on a straight-line basis over the lease term.

On January 1, 2019, we adopted the provisions of ASC Topic 842, Leases (Topic 842), which revises the accounting for leases by requiring certain leases to be recognized as assets and liabilities on the balance sheet, and requiring companies to disclose additional information about their leasing arrangements. We adopted the standard using the modified retrospective method. Based on the practical expedients allowed for in the standard, we did not reassess the current GAAP classification of leases, easements and rights of way that existed as of January 1, 2019, and we did not utilize the hindsight method in determining the assets and liabilities to be recorded for our existing leases on January 1, 2019. The adoption of this standard required us to make significant judgments on whether our revenue and expenditure-related contracts were considered to be leases (or contain leases) under Topic 842, and if contracts were considered to be leases whether they should be considered operating leases or finance leases under the new standard. We do not have any material revenue contracts that are considered leases under Topic 842.

Upon the adoption of this standard, on January 1, 2019, we recorded a $67.5 million increase to our operating lease right-of-use assets, a $18.6 million increase to our accrued expenses and other liabilities and a $48.9 million increase to our long-term operating lease liabilities, related to reflecting our operating leases on our consolidated balance sheet as a result of adopting the new standard. We also recorded a $1.6 million increase to our property, plant and equipment, $0.3 million increase to our accrued expenses and other liabilities and a $1.3 million increase to our other long-term liabilities, related to our finance leases (which were all formerly capital leases under Topic 840) as a result of applying the provisions of the new standard to the leases. The adoption of the standard did not result in a material cumulative effect of accounting change to our consolidated financial statements. The following table summarizes the balance sheet information related to our operating and finance leases at March 31, 2019 (in millions):

Operating Leases
Operating lease right-of-use assets, net	$	61.6
Accrued expenses and other liabilities	$	18.1
Long-term operating lease liabilities	48.2
Total operating lease liabilities	$	66.3
Finance Leases
Property, plant and equipment	$	14.1
Less: accumulated depreciation	2.7
Property, plant and equipment, net	$	11.4
Accrued expenses and other liabilities	$	2.9
Other long-term liabilities	7.1
Total finance lease liabilities	$	10.0

The estimation of our right-of-use assets and lease liabilities requires us to make significant assumptions and judgments about the term of the lease, variable payments, and discount rates. Our operating leases have remaining terms that vary from one year to 14 years and certain of those leases have renewal options to extend the leases from one year to five years, or terminate the leases at our sole discretion. In addition, our finance leases have remaining terms that vary from two years to four years and certain of those leases have options to purchase the lease property by the end of the lease term. We made significant assumptions on the likelihood on whether we would renew our leases or purchase the property at the end of the lease terms in determining the discounted cash flows to measure our right-of-use assets and lease liabilities. The estimation of variable lease payments in determining discounted cash flows, including those with usage-based costs, also required us to make significant assumptions on the timing and nature of the variability of those payments based on the lease terms. We utilized discount rates ranging from 4.9% to 8.3% to estimate the discounted cash flows used in estimating our right-of-use assets and lease liabilities as of March 31, 2019, which were primarily based on our credit-adjusted collateralized incremental borrowing rate.

We recognize operating lease expense and amortize our right-of-use assets for our finance leases on a straight-line basis over the term of the respective leases. We have applied the practical expedient of not separating the lease and non-lease components for our leases where the predominant consideration paid related to the underlying operating and finance lease contracts relate to the lease component. The following table presents the costs and sublease income associated with our operating and finance leases for the three months ended ended March 31, 2019 (in millions):

Operating leases:
Operating lease expense (1)(2)	$	7.5
Sublease income(3)	0.2
Total operating lease expense, net	$	7.3
Finance leases:
Amortization of right-of-use assets(4)	$	0.9
Interest on lease liabilities(5)	0.2
Total finance lease expense	$	1.1

(1) Approximately $4.8 million is included in costs of product/services sold and $2.7 million is included in operations and maintenance expense on our consolidated statements of operations.

(2) Includes short-term and variable lease costs of approximately $0.7 million.

(3) Included in Marketing, Supply and Logistics service revenues on our consolidated statements of operations.

(4) Included in depreciation, amortization and accretion on our consolidated statements of operations.

(5) Included in interest and debt expense, net on our consolidated statements of operations.

The following table presents supplemental cash flow information for our operating and finance leases for the three months endedMarch 31, 2019 (in millions):

Cash paid for lease liabilities:
Operating cash flows from operating leases	$	6.3
Operating cash flows from finance leases	$	0.2
Financing cash flows from finance leases	$	1.1
Right-of-use assets obtained in exchange for lease obligations:
Operating leases	$	0.3
Finance leases	$	1.0

The following table shows the weighted-average remaining lease term and the weighted-average discount rate associated with our operating and finance leases for the three months endedMarch 31, 2019:

Weighted-average remaining lease term (in years):
Operating leases	4.4

New Accounting Pronouncement Issued But Not Yet Adopted

As of March 31, 2019, the following accounting standard had not yet been adopted by us:

In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326), which provides new guidance on how companies should evaluate their accounts and notes receivable and other financial instruments for impairment. The standard requires companies to evaluate their financial instruments for impairment by recording an allowance for doubtful accounts and/or bad debt expense based on certain categories of instruments rather than a specific identification approach. We expect to adopt the provisions of this standard effective January 1, 2020 and are currently evaluating the impact that this standard may have on our consolidated financial statements.

Other

Contingent Consideration. Pursuant to the Stagecoach Gas limited liability company agreement, we may be required to make payments of up to $57 million to Con Edison Gas Pipeline and Storage Northeast, LLC after December 31, 2020 if certain criteria are not met by Stagecoach Gas by December 31, 2020, including achieving certain performance targets on growth capital projects. These growth capital projects depend on the construction of other third-party expansion projects, and during 2017, those third-party projects experienced regulatory and other delays that caused Stagecoach Gas to delay its growth capital projects. As a result, our consolidated balance sheets reflect an other long-term liability of $57 million at March 31, 2019 and December 31, 2018.

Guarantee. CEQP issued a guarantee under which CEQP has agreed to fund 100% of the costs to build the Nautilus gathering system (which is currently estimated to cost $180 million, of which approximately $155.7 million has been spent through March 31, 2019) if Crestwood Permian fails to do so. The Nautilus gathering system is owned by Crestwood Permian Basin LLC, a 50% equity investment of Crestwood Permian. We do not believe this guarantee is probable of resulting in future losses based on our assessment of the nature of the guarantee, the financial condition of the guaranteed party and the period of time that the guarantee has been outstanding, and as a result, we have not recorded a liability on our consolidated balance sheets at March 31, 2019 and December 31, 2018.

Jackalope Acquisition. On April 9, 2019, Crestwood Niobrara LLC (Crestwood Niobrara), our consolidated subsidiary, acquired Williams Partners LP’s (Williams) 50% equity interest in Jackalope for approximately $484.6 million, which was funded through a combination of borrowings under the CMLP credit facility and the issuance of $235 million of new preferred units to CN Jackalope Holdings LLC (Jackalope Holdings) as further discussed in Note 9. The acquisition of this equity interest results in Crestwood Niobrara owning 100% of the equity interests in Jackalope. Crestwood Midstream Operating, LLC (Crestwood Midstream Operating), our consolidated subsidiary, will provide field operations and construction management services for Jackalope.

Risk Management - Notional Amounts and Terms of Companys Derivative Financial Instruments [Abstract]

Risk Management

Risk Management

We are exposed to certain market risks related to our ongoing business operations. These risks include exposure to changing commodity prices. We utilize derivative instruments to manage our exposure to fluctuations in commodity prices, which is discussed below. Additional information related to our derivatives is discussed in Note 6.

Commodity Derivative Instruments and Price Risk Management

Risk Management Activities

We sell NGLs and crude oil to energy related businesses and may use a variety of financial and other instruments including forward contracts involving physical delivery of NGLs, heating oil and crude oil. We periodically enter into offsetting positions to economically hedge against the exposure our customer contracts create. Certain of these contracts and positions are derivative instruments. We do not designate any of our commodity-based derivatives as hedging instruments for accounting purposes. Our commodity-based derivatives are reflected at fair value in the consolidated balance sheets, and changes in the fair value of these derivatives that impact the consolidated statements of operations are reflected in costs of product/services sold. Our commodity-based derivatives that are settled with physical commodities are reflected as an increase to product revenues, and the commodity inventory that is utilized to satisfy those physical obligations is reflected as an increase to costs of product sold in our consolidated statements of operations. The following table summarizes the impact to our consolidated statements of operations related to our commodity-based derivatives reflected in operating revenues and costs of product/services sold during the three months endedMarch 31, 2019 and 2018 (in millions):

	Three Months Ended
	March 31,
	2019			2018
Product revenues	$	104.1		$	97.8
Gain (loss) reflected in costs of product/services sold	(2.9		)	7.8

We attempt to balance our contractual portfolio in terms of notional amounts and timing of performance and delivery obligations. This balance in the contractual portfolio significantly reduces the volatility in costs of product/services sold related to these instruments.

Commodity Price and Credit Risk

Notional Amounts and Terms

The notional amounts and terms of our derivative financial instruments include the following:

	March 31, 2019		December 31, 2018
	Fixed Price Payor	Fixed Price Receiver	Fixed Price Payor	Fixed Price Receiver
Propane, crude and heating oil (MMBbls)	28.8	29.5	27.8	30.1
Natural gas (Bcf)	1.6	1.6	1.8	1.8

Notional amounts reflect the volume of transactions, but do not represent the amounts exchanged by the parties to the financial instruments. Accordingly, notional amounts do not reflect our monetary exposure to market or credit risks. All contracts subject to price risk had a maturity of 36 months or less; however, 82% of the contracted volumes will be delivered or settled within 12 months.

Credit Risk

Inherent in our contractual portfolio are certain credit risks. Credit risk is the risk of loss from nonperformance by suppliers, customers or financial counterparties to a contract. We take an active role in managing credit risk and have established control procedures, which are reviewed on an ongoing basis. We attempt to minimize credit risk exposure through credit policies and periodic monitoring procedures as well as through customer deposits, letters of credit and entering into netting agreements that allow for offsetting counterparty receivable and payable balances for certain financial transactions, as deemed appropriate. The counterparties associated with our price risk management activities are energy marketers and propane retailers, resellers and dealers.

Certain of our derivative instruments have credit limits that require us to post collateral. The amount of collateral required to be posted is a function of the net liability position of the derivative as well as our established credit limit with the respective counterparty. If our credit rating were to change, the counterparties could require us to post additional collateral. The amount of additional collateral that would be required to be posted would vary depending on the extent of change in our credit rating as well as the requirements of the individual counterparty. In addition, we have margin requirements with a New York Mercantile Exchange (NYMEX) broker related to our net asset or liability position with such broker. All collateral amounts have been netted against the asset or liability with the respective counterparty and are reflected in our consolidated balance sheets as assets and liabilities from price risk management activities.

The following table represents the fair value of our commodity derivative instruments with credit-risk related contingent features and their associated collateral (in millions):

	March 31, 2019		December 31, 2018
Aggregate fair value of derivative instruments with credit-risk-related contingent features(1)	$	2.6	$	2.2

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

The accounting standard for fair value measurement establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The three levels of the fair value hierarchy are as follows:

• Level 1—Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 1 primarily consists of financial instruments such as exchange-traded derivatives, listed equities and US government treasury securities.

• Level 2—Pricing inputs are other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors, and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace throughout the full term of the instrument, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace. Instruments in this category include non-exchange-traded derivatives such as over the counter (OTC) forwards, options and physical exchanges.

• Level 3—Pricing inputs include significant inputs that are generally less observable from objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value.

Cash, Accounts Receivable and Accounts Payable

As of March 31, 2019 and December 31, 2018, the carrying amounts of cash, accounts receivable and accounts payable approximate fair value based on the short-term nature of these instruments.

Credit Facility

The fair value of the amounts outstanding under our CMLP credit facility approximates the carrying amounts as of March 31, 2019 and December 31, 2018, due primarily to the variable nature of the interest rate of the instrument, which is considered a Level 2 fair value measurement.

Senior Notes

We estimate the fair value of our senior notes primarily based on quoted market prices for the same or similar issuances (representing a Level 2 fair value measurement). The following table reflects the carrying amount (reduced for deferred financing costs associated with the respective notes) and fair value of our senior notes (in millions):

	March 31, 2019				December 31, 2018
	Carrying  Amount		Fair Value		Carrying  Amount		Fair Value
2023 Senior Notes	$	694.0	$	720.8	$	693.6	$	668.1
2025 Senior Notes	$	493.6	$	514.8	$	493.4	$	466.2

Financial Assets and Liabilities

As of March 31, 2019 and December 31, 2018, we held certain assets and liabilities that are required to be measured at fair value on a recurring basis, which include our derivative instruments related to heating oil, crude oil, and NGLs. Our derivative instruments consist of forwards, swaps, futures, physical exchanges and options.

Our derivative instruments that are traded on the NYMEX have been categorized as Level 1.

Our derivative instruments also include OTC contracts, which are not traded on a public exchange. The fair values of these derivative instruments are determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets. These instruments have been categorized as Level 2.

Our OTC options are valued based on the Black Scholes option pricing model that considers time value and volatility of the underlying commodity. The inputs utilized in the model are based on publicly available information as well as broker quotes. These options have been categorized as Level 2.

Our financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels.

The following tables set forth by level within the fair value hierarchy, our financial instruments that were accounted for at fair value on a recurring basis at March 31, 2019 and December 31, 2018 (in millions):

Credit Facility

At March 31, 2019, Crestwood Midstream had $584.0 million of available capacity under its credit facility considering the most restrictive debt covenants in its credit agreement. At March 31, 2019 and December 31, 2018, Crestwood Midstream’s outstanding standby letters of credit were $73.0 million and $68.0 million. Borrowings under the credit facility accrue interest at prime or Eurodollar based rates plus applicable spreads, which resulted in interest rates between 4.74% and 6.75% at March 31, 2019 and 4.63% and 6.75% at December 31, 2018. The weighted-average interest rate as of March 31, 2019 and December 31, 2018 was 4.79% in both periods.

Crestwood Midstream is required under its credit agreement to maintain a net debt to consolidated EBITDA ratio (as defined in its credit agreement) of not more than 5.50 to 1.0, a consolidated EBITDA to consolidated interest expense ratio (as defined in its credit agreement) of not less than 2.50 to 1.0, and a senior secured leverage ratio (as defined in its credit agreement) of not more than 3.75 to 1.0. At March 31, 2019, the net debt to consolidated EBITDA ratio was approximately 4.11 to 1.0, the consolidated EBITDA to consolidated interest expense ratio was approximately 4.41 to 1.0, and the senior secured leverage ratio was 1.36 to 1.0.

In April 2019, Crestwood Niobrara acquired the remaining 50% equity interest in Jackalope and funded approximately $250 million of the total purchase price through borrowings under Crestwood Midstream’s credit facility. Contemporaneously with the closing of the remaining interest in Jackalope, Crestwood Midstream entered into the First Amendment to the Second Amended and Restated Credit Agreement to modify certain defined terms and calculations, among other things, to account for the Jackalope acquisition. The other debt covenants under the amended credit agreement are materially consistent with the credit facility that existed at March 31, 2019.

Senior Notes

In April 2019, Crestwood Midstream issued $600 million of 5.625% unsecured senior notes due 2027 (the 2027 Senior Notes). The 2027 Senior Notes will mature on May 1, 2027, and interest is payable semiannually in arrears on May 1 and November 1 of each year, beginning November 1, 2019. The net proceeds from this offering of approximately $591.1 million were used to repay a portion of the outstanding borrowings under our credit facility, which included the borrowings that were used to fund the acquisition of the remaining 50% equity interest in Jackalope.

Earnings Per Share [Abstract]

Earnings Per Limited Partner Unit

Earnings Per Limited Partner Unit

Our net income (loss) attributable to Crestwood Equity Partners is allocated to the subordinated and limited partner unitholders based on their ownership percentage after giving effect to net income attributable to the preferred units. We calculate basic net income per limited partner unit using the two-class method. Diluted net income per limited partner unit is computed using the treasury stock method, which considers the impact to net income attributable to Crestwood Equity Partners and limited partner units from the potential issuance of limited partner units.

We exclude potentially dilutive securities from the determination of diluted earnings per unit (as well as their related income statement impacts) when their impact on net income attributable to Crestwood Equity Partners per limited partner unit is anti-dilutive. The following table summarizes information regarding the weighted-average of common units excluded during the three months endedMarch 31, 2019 and 2018:

Preferred Units

Subject to certain conditions, the holders of the preferred units have the right to convert their preferred units into (i) common units on a 1-for-10 basis or (ii) a number of common units determined pursuant to a conversion ratio set forth in Crestwood Equity’s partnership agreement upon the occurrence of certain events, such as a change in control. The preferred units have voting rights that are identical to the voting rights of the common units and will vote with the common units as a single class, with each preferred unit entitled to one vote for each common unit into which such preferred unit is convertible, except that the preferred units are entitled to vote as a separate class on any matter on which all unitholders are entitled to vote that adversely affects the rights, powers, privileges or preferences of the preferred units in relation to Crestwood Equity’s other securities outstanding.

Common Units

We have an employee unit purchase plan under which employees of the general partner may purchase our common units through payroll deductions up to a maximum of 10% of the employees’ eligible compensation, not to exceed $25,000 for any calendar year. During the three months endedMarch 31, 2019, there were 789 common units purchased under the plan. For a further description of our employee unit purchase plan, see our 2018 Annual Report on Form 10-K.

Distributions

Crestwood Equity

Limited Partners. A summary of CEQP’s limited partner quarterly cash distributions for the three months endedMarch 31, 2019 and 2018 is presented below:

Record Date	Payment Date	Per Unit Rate		Cash Distributions (in millions)
2019
February 7, 2019	February 14, 2019	$	0.60	$	43.1
2018
February 7, 2018	February 14, 2018	$	0.60	$	42.7

Preferred Unit Holders. During the three months endedMarch 31, 2019 and 2018, we made cash distributions to our preferred unitholders of approximately $15.0 million in both periods. On April 18, 2019, the board of directors of our general partner authorized a cash distribution to our preferred unitholders of approximately $15.0 million for the quarter ended March 31, 2019.

Crestwood Midstream

During the three months endedMarch 31, 2019 and 2018, Crestwood Midstream paid cash distributions of $57.8 million and $60.5 million to Crestwood Equity.

Non-Controlling Partner

Crestwood Niobrara LLC (Crestwood Niobrara) issued preferred interests (Series A-2 Preferred Units) to Jackalope Holdings, which are reflected as non-controlling interest in our consolidated financial statements. Subject to certain restrictions, we have the ability to redeem the Series A-2 Preferred Units for an amount in cash or CEQP common units equal to an amount necessary for Jackalope Holdings to achieve a certain rate of return. During the three months endedMarch 31, 2019, Crestwood Niobrara paid cash distributions of $3.3 million to Jackalope Holdings. In April 2019, Crestwood Niobrara paid a cash distribution of $3.3 million to Jackalope Holdings for the quarter ended March 31, 2019.

In conjunction with the acquisition of the remaining 50% equity interest in Jackalope in April 2019, Crestwood Niobrara issued $235 million of preferred interests (Series A-3 Preferred Units) to Jackalope Holdings. Crestwood Niobrara will be required to make quarterly cash distributions on the Series A-3 Preferred Units within 30 days after the end of each quarter beginning with the quarter ended June 30, 2019. In connection with the issuance of the Series A-3 Preferred Units, we entered into a Third Amended and Restated Limited Liability Company Agreement (Crestwood Niobrara Amended Agreement) with Jackalope Holdings for Crestwood Niobrara and modified the provisions related to the redemption and conversion of the Series A-2 and Series A-3 Preferred Units. In addition, we amended our registration rights agreement with Jackalope Holdings and entered into the First Amendment to the Registration Rights Agreement to conform with certain provisions of the Crestwood Niobrara Amended Agreement and the issuance of the Series A-3 Preferred Units.

Other

In February 2019, Crestwood Equity issued 238,263 performance units under the Crestwood Equity Partners LP Long Term Incentive Plan (Crestwood LTIP). The performance units are designed to provide an incentive for continuous employment to certain key employees. The vesting of performance units is subject to the attainment of certain performance and market goals over a three-year period, and entitle a participant to receive common units of Crestwood Equity without payment of an exercise price upon vesting. As of March 31, 2019, we had total unamortized compensation expense of approximately $5.7 million related to these performance units, which we expect will be amortized during the next three years. We recognized compensation expense of approximately $1.4 million under the Crestwood LTIP related to these performance units during the three months ended March 31, 2019, which is included in general and administrative expenses on our consolidated statements of operations.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

Legal Proceedings

We are periodically involved in litigation proceedings. If we determine that a negative outcome is probable and the amount of loss is reasonably estimable, then we accrue the estimated amount. The results of litigation proceedings cannot be predicted with certainty. We could incur judgments, enter into settlements or revise our expectations regarding the outcome of certain matters, and such developments could have a material adverse effect on our results of operations or cash flows in the period in which the amounts are paid and/or accrued. As of March 31, 2019 and December 31, 2018, both CEQP and CMLP had approximately $0.2 million and $0.1 million accrued for outstanding legal matters. Based on currently available information, we believe it is remote that future costs related to known contingent liability exposures for which we can estimate will exceed current accruals by an amount that would have a material adverse impact on our consolidated financial statements. As we learn new facts concerning contingencies, we reassess our position both with respect to accrued liabilities and other potential exposures.

Any loss estimates are inherently subjective, based on currently available information, and are subject to management’s judgment and various assumptions. Due to the inherently subjective nature of these estimates and the uncertainty and unpredictability surrounding the outcome of legal proceedings, actual results may differ materially from any amounts that have been accrued.

Regulatory Compliance

In the ordinary course of our business, we are subject to various laws and regulations. In the opinion of our management, compliance with current laws and regulations will not have a material effect on our results of operations, cash flows or financial condition.

Environmental Compliance

Our operations are subject to stringent and complex laws and regulations pertaining to worker health, safety, and the environment. We are subject to laws and regulations at the federal, state, regional and local levels that relate to air and water quality, hazardous and solid waste management and disposal, and other environmental matters. The cost of planning, designing, constructing and operating our facilities must incorporate compliance with environmental laws and regulations and safety standards. Failure to comply with these laws and regulations may trigger a variety of administrative, civil and potentially criminal enforcement measures.

During 2014, we experienced three releases totaling approximately 28,000 barrels of produced water on our Arrow water gathering system located on the Fort Berthold Indian Reservation in North Dakota. We immediately notified the National Response Center, the Three Affiliated Tribes and numerous other regulatory authorities. Thereafter, we contained and cleaned up the releases, and placed the impacted segments of these water lines back into service. In May 2015, we experienced a release of approximately 5,200 barrels of produced water on our Arrow water gathering system, immediately notified numerous regulatory authorities and other third parties, and thereafter contained and cleaned up the releases.

In August 2015, we received a notice of violation from the Three Affiliated Tribes’ Environmental Division related to our 2014 produced water releases on the Fort Berthold Indian Reservation. The notice of violation imposes fines and requests reimbursements exceeding $1.1 million; however, the notice of violation was stayed on September 15, 2015. Our discussions regarding the notice of violation continue with the Three Affiliated Tribes.

We will continue our remediation efforts to ensure the impacted lands are restored to their prior state. We believe these releases are insurable events under our policies, and we have notified our carriers of these events. We have not recorded an insurance receivable as of March 31, 2019.

At March 31, 2019 and December 31, 2018, our accrual of approximately $1.8 million was based on our undiscounted estimate of amounts we will spend on compliance with environmental and other regulations, and any associated fines or penalties (including the Arrow water releases described above). We estimate that our potential liability for reasonably possible outcomes related to our environmental exposures could range from approximately $1.8 million to $3.3 million at March 31, 2019.

Self-Insurance

We utilize third-party insurance subject to varying retention levels of self-insurance, which management considers prudent. Such self-insurance relates to losses and liabilities primarily associated with medical claims, workers’ compensation claims and general, product, vehicle and environmental liability. Losses are accrued based upon management’s estimates of the aggregate liability for claims incurred using certain assumptions followed in the insurance industry and based on past experience. The primary assumption utilized is actuarially determined loss development factors. The loss development factors are based primarily on historical data. Our self insurance reserves could be affected if future claim developments differ from the historical trends. We believe changes in health care costs, trends in health care claims of our employee base, accident frequency and severity and other factors could materially affect the estimate for these liabilities. We continually monitor changes in employee demographics, incident and claim type and evaluate our insurance accruals and adjust our accruals based on our evaluation of these qualitative data points. We are liable for the development of claims for our disposed retail propane operations, provided they were reported prior to August 1, 2012. The following table summarizes CEQP’s and CMLP’s self-insurance reserves at March 31, 2019 and December 31, 2018 (in millions):

	CEQP				CMLP
	March 31, 2019		December 31, 2018		March 31, 2019		December 31, 2018
Self-insurance reserves(1)	$	11.4	$	11.3	$	10.0	$	9.6

(1) At March 31, 2019, CEQP and CMLP classified approximately $7.4 million and $6.3 million, respectively of these reserves as other long-term liabilities on their consolidated balance sheets.

Guarantees and Indemnifications. We are involved in various joint ventures that sometimes require financial and performance guarantees. In a financial guarantee, we are obligated to make payments if the guaranteed party fails to make payments under, or violates the terms of, the financial arrangement. In a performance guarantee, we provide assurance that the guaranteed party will execute on the terms of the contract. If they do not, we are required to perform on their behalf. We also periodically provide indemnification arrangements related to assets or businesses we have sold. For a further description of our guarantees associated with our joint ventures, see Note 4.

Our potential exposure under guarantee and indemnification arrangements can range from a specified amount to an unlimited dollar amount, depending on the nature of the claim, specificity as to duration, and the particular transaction. As of March 31, 2019 and December 31, 2018, we have no amounts accrued for these guarantees.

Revenue Recognition [Abstract]

Revenue Recognition

Revenues

Contract Assets and Contract Liabilities

Our contract assets and contract liabilities are reported in a net position on a contract-by-contract basis at the end of each reporting period. Our receivables related to our Topic 606 revenue contracts totaled $225.0 million and $209.7 million for both CEQP and CMLP at March 31, 2019 and December 31, 2018, and are included in accounts receivable on our consolidated balance sheets. Our contract assets are included in other non-current assets on our consolidated balance sheets. Our contract liabilities primarily consist of current and non-current deferred revenues. On our consolidated balance sheets, our current deferred revenues are included in accrued expenses and other liabilities and our non-current deferred revenues are included in other long-term liabilities. The majority of revenues associated with our deferred revenues is expected to be recognized as the performance obligations under the related contracts are satisfied over the next 13 years.

The following table provides a summary of the opening and closing balances of our contract assets and contract liabilities (in millions):

	Balance at March 31, 2019		Balance at December 31, 2018
Contract Assets (Non-current)	$	0.9	$	1.0
Contract Liabilities (Current)(1)	$	12.0	$	12.0
Contract Liabilities (Non-current)(1)	$	71.5	$	65.4

(1) During the three months endedMarch 31, 2019, we recognized revenues of approximately $2.8 million that were previously included in contract liabilities (current) at December 31, 2018. The remaining change in our contract liabilities during the three months endedMarch 31, 2019, primarily related to capital reimbursements associated with our revenue contracts and revenue deferrals associated with our contracts with increasing (decreasing) rates.

The following table summarizes the transaction price allocated to our remaining performance obligations under certain contracts that have not been recognized as of March 31, 2019(in millions):

Remainder of 2019	$	21.4
2020	23.2
2021	9.4
2022	7.3
2023	7.3
Thereafter	3.3
Total	$	71.9

Our remaining performance obligations presented in the table above exclude estimates of variable rate escalation clauses in our contracts with customers, and is generally limited to fixed-fee and percentage-of-proceeds service contracts which have fixed pricing and minimum volume terms and conditions. Our remaining performance obligations generally exclude, based on the following practical expedients that we elected to apply, disclosures for (i) variable consideration allocated to a wholly-unsatisfied promise to transfer a distinct service that forms part of the identified single performance obligation; (ii) unsatisfied performance obligations where the contract term is one year or less; and (iii) contracts for which we recognize revenues as amounts are invoiced.

Disaggregation of Revenues

The following tables summarize our revenues from contracts with customers disaggregated by type of product/service sold and by commodity type for each of our segments for the three months endedMarch 31, 2019 and 2018 (in millions). We believe this summary best depicts how the nature, amount, timing and uncertainty of our revenues and cash flows are affected by economic factors.

As of March 31, 2019, the following accounting standard had not yet been adopted by us:

In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-13, Financial Instruments - Credit Losses (Topic 326), which provides new guidance on how companies should evaluate their accounts and notes receivable and other financial instruments for impairment. The standard requires companies to evaluate their financial instruments for impairment by recording an allowance for doubtful accounts and/or bad debt expense based on certain categories of instruments rather than a specific identification approach. We expect to adopt the provisions of this standard effective January 1, 2020 and are currently evaluating the impact that this standard may have on our consolidated financial statements.
