NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
1.    ORGANIZATION AND NATURE OF BUSINESS
 
Blueknight Energy Partners, L.P. and(together with its subsidiaries, (collectively, the “Partnership”) is a publicly traded master limited partnership with operations in twenty-fourtwenty-six states. The Partnership provides integrated terminalling, storage, processing, gathering, transportation and marketing services for companies engaged in the production, distribution and marketing of crude oil and asphalt products. The Partnership manages its operations through four operating segments: (i) asphalt terminalling services, (ii) crude oil terminalling and storage services, (iii) crude oil pipeline services and (iv) crude oil trucking and producer field services. The Partnership’s common units and preferred units, which represent limited partnership interests in the Partnership, are listed on the NASDAQ Global Market under the symbols “BKEP” and “BKEPP,” respectively. The Partnership was formed in February 2007 as a Delaware master limited partnership initially to own, operate and develop a diversified portfolio of complementary midstream energy assets.

On October 5, 2016, the Partnership completed the following transactions (the “Ergon Transactions”): (i) a subsidiary of Ergon, Inc. (together with its subsidiaries, “Ergon”) purchased 100% of the outstanding voting stock of Blueknight GP Holding, L.L.C., which owns 100% of the capital stock of the Partnership’s general partner, Blueknight Energy Partners G.P., L.L.C., pursuant to a Membership Interest Purchase Agreement dated July 19, 2016 among CB-Blueknight, LLC, an indirect wholly-owned subsidiary of Charlesbank Capital Partners, LLC (together with its affiliates and subsidiaries, “Charlesbank”), Blueknight Energy Holding, Inc., an indirect wholly-owned subsidiary of Vitol Holding B.V. (together with its affiliates and subsidiaries “Vitol”), and Ergon Asphalt Holdings, LLC, a wholly-owned subsidiary of Ergon (the “Ergon Change of Control”); (ii) Ergon contributed nine asphalt terminals plus $22.1 million in cash in return for total consideration of approximately $144.7 million, which consisted of the issuance of 18,312,968 of Series A preferred units in a private placement; and (iii) Ergon acquired an aggregate of $5.0 million of common units for cash in a private placement, pursuant to a Contribution Agreement between the Partnership and Ergon.

The proceeds of loans made under the amended and restated credit agreement may be used for working capital and other general corporate purposes of the Partnership. All references herein to the credit agreement on or after June 28, 2013,May 11, 2017, refer to the amended and restated credit agreement, as amended on September 15, 2014.agreement.

or penalty (other than customary LIBOR breakage costs), subject to certain notice requirements. The credit agreement requires mandatory prepayments of amounts outstanding thereunder with the net proceeds of certain asset sales, property or casualty insurance claims, and condemnation proceedings, unless the Partnership reinvests such proceeds in accordance with the credit agreement, but these mandatory prepayments will not require any reduction of the lenders’ commitments under the credit agreement.

Borrowings under the credit agreement bear interest, at the Partnership’s option, at either the reserve-adjusted eurodollar rate (as defined in the credit agreement) plus an applicable margin that ranges from 2.0% to 3.0% or the alternate base rate (the highest of the agent bank’s prime rate, the federal funds effective rate plus 0.5%, and the 30-day eurodollar rate plus 1.0%) plus an applicable margin that ranges from 1.0% to 2.0%.  The Partnership pays a per annum fee on all letters of credit issued under the credit agreement, which fee equals the applicable margin for loans accruing interest based on the eurodollar rate, and the Partnership pays a commitment fee ranging from 0.375% to 0.5% on the unused commitments under the credit agreement.  The credit agreement does not have a floor for the alternate base rate or the eurodollar rate. The applicable margins for the Partnership’s interest rate, the letter of credit fee and the commitment fee vary quarterly based on the Partnership’s consolidated total leverage ratio (as defined in the credit agreement, being generally computed as the ratio of consolidated total debt to consolidated earnings before interest, taxes, depreciation, amortization and certain other non-cash charges).

If any default occurs under the credit agreement, or if the Partnership is unable to make any of the representations and warranties in the credit agreement, the Partnership will be unable to borrow funds or to have letters of credit issued under the credit agreement.

10.    LONG-TERM INCENTIVE PLAN

In July 2007, the General Partnergeneral partner adopted the Long-Term Incentive Plan (the “LTIP”). The compensation committee of the Board administers the LTIP. Effective April 29, 2014, the Partnership’s unitholders approved an amendment to the LTIP to increase the number of common units reserved for issuance under the incentive plan by 1,500,000 common units from 2,600,000 common units to 4,100,000 common units. The common units are deliverable upon vesting.  Although other types of awards are contemplated under the LTIP, currently outstanding awards include “phantom” units, which convey the right to receive common units upon vesting, and “restricted” units, which are grants of common units restricted until the time of vesting. Certain of the phantom unit awards also include distribution equivalent rights (“DERs”).
 
Subject to applicable earning criteria, a DER entitles the grantee to a cash payment equal to the cash distribution paid on an outstanding common unit prior to the vesting date of the underlying award. Recipients of restricted units are entitled to receive cash distributions paid on common units during the vesting period which distributions are reflected initially as a reduction of partners’ capital. Distributions paid on units which ultimately do not vest are reclassified as compensation expense.  Awards


granted to date are equity awards and, accordingly, the fair value of the awards as of the grant date is expensed over the vesting period.  

In connection with each anniversary of joining the Board, restricted common units are granted to the independent directors. The units vest in one-third increments over three years. The following table includes information on outstanding grants made to the directors under the LTIP:

The unrecognized estimated compensation cost of outstanding phantom units at June 30, 20162017, was $2.82.9 million, which will be recognized over the remaining vesting period.

In September 2012, Mr. Mark Hurley was granted 500,000 phantom units under the LTIP upon his employment as the Chief Executive Officer of the General Partner.general partner. These grants are equity awards under ASC 718 – Stock Compensation, and, accordingly, the fair value of the awards as of the grant date is expensed over the vesting period. These units vest ratably over


five years pursuant to the Employee Phantom Unit Agreement between Mr. Hurley and the General Partnergeneral partner and do not include DERs. The weighted average grant date fair value for the units of $5.62 was determined based on the closing market price of the Partnership’s common units on the grant date of the award, less the present value of the estimated distributions to be paid to holders of an outstanding common unit prior to the vesting of the underlying award. The value of this award grant was approximately $2.8 million on the grant date, and the unrecognized estimated compensation cost at June 30, 20162017, was $0.70.1 million and will be expensed over the remaining vesting period.

The Partnership’s equity-based incentive compensation expense for each of the three months ended June 30, 20152016 and 2016,2017 was $0.7 million and $0.6 million, respectively.million. The Partnership’s equity-based incentive compensation expense for both the six months ended June 30, 20152016 and 2016,2017 was $1.2 million.million and $1.1 million, respectively.

11.    EMPLOYEE BENEFIT PLANS

Under the Partnership’s 401(k) Plan, which was instituted in 2009, employees who meet specified service requirements may contribute a percentage of their total compensation, up to a specified maximum, to the 401(k) Plan. The Partnership may match each employee’s contribution, up to a specified maximum, in full or on a partial basis. The Partnership recognized expense of $0.4 million and $0.3 million respectively, for each of the three months ended June 30, 20152016 and 2016,2017, for discretionary contributions under the 401(k) Plan. The Partnership recognized expense of $0.8 million and $0.6 million respectively, for each of the six months ended June 30, 20152016 and 2016,2017, for discretionary contributions under the 401(k) Plan.

The Partnership may also make annual lump-sum contributions to the 401(k) Plan irrespective of the employee’s contribution match. The Partnership may make a discretionary annual contribution in the form of profit sharing calculated as a percentage of an employee’s eligible compensation. This contribution is retirement income under the qualified 401(k) Plan. Annual profit sharing contributions to the 401(k) Plan are submitted to and approved by the Board. The Partnership recognized expense of $0.1 million and $0.2 million respectively, for each of the three months ended June 30, 20152016 and 2016,2017, for discretionary profit sharing contributions under the 401(k) Plan. The Partnership recognized expense of $0.3 million and $0.4 million respectively, for each of the six months ended June 30, 20152016 and 2016,2017, for discretionary profit sharing contributions under the 401(k) Plan.

Under the Partnership’s Employee Unit Purchase Plan (the “Unit Purchase Plan”), which was instituted in January 2015, employees have the opportunity to acquire or increase their ownership of common units representing limited partner interests in the Partnership. Eligible employees who enroll in the Unit Purchase Plan may elect to have a designated whole percentage, up to a specified maximum, of their eligible compensation for each pay period withheld for the purchase of common units at a discount to the then current market value. A maximum of 1,000,000 common units may be delivered under the Unit Purchase Plan, subject to adjustment for a recapitalization, split, reorganization, or similar event pursuant to the terms of the Unit Purchase Plan. The Partnership recognized compensation expense of less than $0.1 million for bothduring each of the three months ended June 30, 2015 and 2016, in connection with the Unit Purchase Plan. The Partnership recognized compensation expense of less than $0.1 million for both the six months ended June 30, 20152016 and 2016,2017, in connection with the Unit Purchase Plan.
 
12.    FAIR VALUE MEASUREMENTS
 
The Partnership uses valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow), and the cost approach (cost to replace the service capacity of an asset or replacement cost) to value assets and liabilities required to be measured at fair value, as appropriate. The Partnership uses an exit price when determining the fair value. The exit price represents amounts that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.
 


The Partnership utilizes a three-tier fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:
Level 1Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.
Level 2Inputs other than quoted prices that are observable for these assets or liabilities, either directly or indirectly.  These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.
Level 3Unobservable inputs in which there is little market data, which requires the reporting entity to develop its own assumptions.
 
This hierarchy requires the use of observable market data, when available, to minimize the use of unobservable inputs when determining fair value.  In periods in which they occur, the Partnership recognizes transfers into and out of Level 3 as of the end of the reporting period. There were no transfers during the six months ended June 30, 2017. Transfers out of Level 3 represent existing assets and liabilities that were classified previously as Level 3 for which the observable inputs became a more significant portion of the fair value estimates. Determining the appropriate classification of the Partnership’s fair value measurements within the fair value hierarchy requires management’s judgment regarding the degree to which market data is observable or corroborated by observable market data.



The Partnership’s recurring financial assets and liabilities subject to fair value measurements and the necessary disclosures are as follows (in thousands):

Fair Value of Other Financial Instruments

The following disclosure of the estimated fair value of financial instruments is made in accordance with accounting guidance for financial instruments. The Partnership has determined the estimated fair values by using available market information and valuation methodologies. Considerable judgment is required in interpreting market data to develop the estimates of fair value. The use of different market assumptions or valuation methodologies may have a material effect on the estimated fair value amounts.
 
At June 30, 2016,2017, the carrying values on the unaudited condensed consolidated balance sheets for cash and cash equivalents (classified as Level 1), accounts receivable, and accounts payable approximate their fair value because of their short-term nature.
 
Based on the borrowing rates currently available to the Partnership for credit agreement debt with similar terms and maturities and consideration of the Partnership’s non-performance risk, long-term debt associated with the Partnership’s credit agreement at June 30, 20162017 approximates its fair value. The fair value of the Partnership’s long-term debt was calculated using


observable inputs (LIBOR for the risk freerisk-free component) and unobservable company-specific credit spread information.  As such, the Partnership considers this debt to be Level 3.

13.    OPERATING SEGMENTS

The Partnership’s operations consist of four operating segments: (i) asphalt terminalling services, (ii) crude oil terminalling and storage services, (iii) crude oil pipeline services, and (iv) crude oil trucking and producer field services.

CRUDE OIL PIPELINE SERVICES —The Partnership owns and operates threepipeline systems the Mid-Continent system, the East Texas system and the Eagle North System, that gather crude oil purchased by its customers and transports it to refiners, to common carrier pipelines for ultimate delivery to refiners or to terminalling and storage facilities owned by the Partnership and others. The Partnership also engages in marketing crude oil that is purchased at production leases and transported on its pipelines. The Partnership refers to its pipeline system located in Oklahoma and the Texas Panhandle as the Mid-Continent system. It refersRevenue for the sale of crude oil is recognized when title to its secondthe crude oil transfers to the customer and is based on contractual prices for the sale of crude oil. The Partnership previously owned and operated the East Texas pipeline system, which is located in Texas, asTexas. On April 18, 2017, the Partnership sold the East Texas system. The Partnership refers to its third system, originating in Cushing, Oklahoma, and terminating in Ardmore, Oklahoma, as the Eagle North system.See Note 5 for additional information.


 
CRUDE OIL TRUCKING AND PRODUCER FIELD SERVICES — The Partnership uses its owned and leased tanker trucks to gather crude oil for its customers at remote wellhead locations generally not covered by pipeline and gathering systems and to transport the crude oil to aggregation points and storage facilities located along pipeline gathering and transportation systems.  Crude oil producer field services consist of a number of producer field services, ranging from gathering condensates from natural gas companies to hauling produced water to disposal wells.
 
The Partnership’s management evaluates performance based upon segment operating margin, which includes revenues from related parties and external customers less operating expenses excluding depreciation and amortization. The non-GAAP measure of operating margin, excluding depreciation and amortization, (in the aggregate and by segment) is presented in the following table. The Partnership computes the components of operating margin by using amounts that are determined in accordance with GAAP. A reconciliation of operating margin, excluding depreciation and amortization, to income before income taxes, which is its nearest comparable GAAP financial measure, is included in the following table. The Partnership believes that investors benefit from having access to the same financial measures being utilized by management. Operating margin, excluding depreciation and amortization, is an important measure of the economic performance of the Partnership’s core operations. This measure forms the basis of the Partnership’s internal financial reporting and is used by its management in deciding how to allocate capital resources among segments.  The Partnership believes that investors benefit from having access to the same financial measures being utilized by management. The non-GAAP measure of total operating margin, excluding depreciation and amortization, is presented in the following table. Total operating margin, excluding depreciation and amortization, is an important measure of the economic performance of the Partnership’s core operations. The Partnership computes the components of total operating margin by using amounts that are determined in accordance with GAAP. A reconciliation of total operating margin, excluding depreciation and amortization, to income before income taxes, which is its nearest comparable GAAP financial measure, is included in the following table.  Income before income taxes, alternatively, includes expense items, such as depreciation and amortization, general and administrative expenses and interest expense, which management does not consider when evaluating the core profitability of the Partnership’s operations.

14.    COMMITMENTS AND CONTINGENCIES

The Partnership is from time to time subject to various legal actions and claims incidental to its business. Management believes that these legal proceedings will not have a material adverse effect on the financial position, results of operations or cash flows of the Partnership. Once management determines that information pertaining to a legal proceeding indicates that it is probable that a liability has been incurred and the amount of such liability can be reasonably estimated, an accrual is established equal to its estimate of the likely exposure.

The Partnership may become the subject of additional private or government actions regarding these matters in the future.  Litigation may be time-consuming, expensive and disruptive to normal business operations, and the outcome of litigation is difficult to predict.  The defense of these lawsuits may result in the incurrence of significant legal expense, both directly and as the result of the Partnership’s indemnification obligations.  The litigation may also divert management’s attention from the Partnership’s operations which may cause its business to suffer.  An unfavorable outcome in any of these matters may have a material adverse effect on the Partnership’s business, financial condition, results of operations, cash flows, ability to make distributions to its unitholders, the trading price of the Partnership’s common units and its ability to conduct its business. All or a portion of the defense costs and any amount the Partnership may be required to pay to satisfy a judgment or settlement of these claims may or may not be covered by insurance.
  
The Partnership has contractual obligations to perform dismantlement and removal activities in the event that some of its asphalt product and residual fuel oil terminalling and storage assets are abandoned. These obligations include varying levels of activity including completely removing the assets and returning the land to its original state. The Partnership has determined that the settlement dates related to the retirement obligations are indeterminate. The assets with indeterminate settlement dates have been in existence for many years and with regular maintenance will continue to be in service for many years to come. Also, it is not possible to predict when demands for the Partnership’s terminalling and storage services will cease, and the Partnership does not believe that such demand will cease for the foreseeable future.  Accordingly, the Partnership believes the date when these assets will be abandoned is indeterminate. With no reasonably determinable abandonment date, the Partnership cannot reasonably estimate the fair value of the associated asset retirement obligations.  Management believes that if the Partnership’s asset retirement obligations were settled in the foreseeable future the present value of potential cash flows that would be required to settle the obligations based on current costs are not material.  The Partnership will record asset retirement obligations for these assets in the period in which sufficient information becomes available for it to reasonably determine the settlement dates.

15.    INCOME TAXES
  
The anticipated after-tax economic benefit of an investment in the Partnership’s units depends largely on the Partnership being treated as a partnership for federal income tax purposes. If less than 90% of the gross income of a publicly traded partnership, such as the Partnership, for any taxable year is “qualifying income” from sources such as the transportation, storage, marketing (other than to end users), or processing of crude oil, natural gas or products thereof, rents from real property leased to unrelated parties, interest, dividends or certain other specified sources, that partnership will be taxable as a


corporation under Section 7704 of the Internal Revenue Code for federal income tax purposes for that taxable year and all subsequent years.

If the Partnership were treated as a corporation for federal income tax purposes, then it would pay federal income tax on its income at the corporate tax rate, which is currently a maximum of 35%, and would likely pay state income tax at varying rates.


Distributions would generally be taxed again to unitholders as corporate distributionsdividends and none of the Partnership’s income, gains, losses, deductions or credits would flow through to its unitholders. Because a tax would be imposed upon the Partnership as an entity, cash available for distribution to its unitholders would be substantially reduced. Treatment of the Partnership as a corporation would result in a material reduction in the anticipated cash flow and after-tax return to unitholders and thus would likely result in a substantial reduction in the value of the Partnership’s units.

The Partnership has entered into storage contracts with third party customers and leases with third party lessees with respect to all of its asphalt facilities. In the second quarter of 2009, the Partnership submitted a request for a ruling from the IRS that rental income from the leases constitutes “qualifying income.” In October 2009, the Partnership received a favorable ruling from the IRS to the effect that rental income received under the leases with third party lessees constitutes qualifying income. As part of this ruling, however, the Partnership agreed to transfer, and has transferred, certain of its asphalt processing assets and related fee income to a subsidiary taxed as a corporation. This transfer occurred in the first quarter of 2010.  Such subsidiary’s income is subject to tax at the applicable federal, state and local income tax rates.  Distributions from this subsidiary generally are taxed again to the Partnership’s unitholders as corporate distributions and none of the income, gains, losses, deductions or credits of this subsidiary will flow through to the Partnership’s unitholders.

In relation to the Partnership’s taxable subsidiary, the tax effects of temporary differences between the tax basis of assets and liabilities and their financial reporting amounts at June 30, 20162017, are presented below (dollars in thousands):

Difference in bases of property, plant and equipment$871
$793
Deferred tax asset871

The Partnership has considered the taxable income projections in future years, whether the carryforward period is so brief that it would limit realization of tax benefits, whether future revenue and operating cost projections will produce enough taxable income to realize the deferred tax asset based on existing service rates and cost structures, and the Partnership’s earnings history exclusive of the loss that created the future deductible amount for the Partnership’s subsidiary that is taxed as a corporation for purposes of determining the likelihood of realizing the benefits of the deferred tax assets. As a result of the Partnership’s consideration of these factors, the Partnership has provided a full valuation allowance against its deferred tax asset as of June 30, 2016.2017.

16.    RECENTLY ISSUED ACCOUNTING STANDARDS

Except as discussed below and in our 2015the 2016 Annual Report on Form 10-K, there have been no new accounting pronouncements that have become effective or have been issued during the six months ended June 30, 20162017 that are of significance or potential significance to usthe Partnership.

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” The amendments in this Updateupdate create Topic 606, Revenue from Contracts with Customers, and supersede the revenue recognition requirements in Topic 605, Revenue Recognition, including most industry-specific revenue recognition guidance throughout the Industry Topics of the Codification. In addition, the amendments supersede the cost guidance in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts, and create new Subtopic 340-40, Other Assets and Deferred Costs-Contracts with Customers. In summary, the core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In AugustThroughout 2015 and 2016, the FASB has issued Accounting Standards Updatea series of subsequent updates to the revenue recognition guidance in Topic 606, including ASU No. 2015-14, “RevenueRevenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, and ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers.



The amendmentamendments in this update deferred the effective date of ASU 2014-09, by one year toASU 2016-08, ASU 2016-10, ASU 2016-12, and ASU 2016-20 are effective for public entities for annual reporting periods beginning after December 15, 2017, includingand for interim reporting periods within that reporting period. EarlierEarly application is permitted only as offor annual reporting periods beginning after December 15, 2016.

The Partnership is evaluating the impact of this standard, which will be adopted as of January 1, 2018.

The Partnership is currently assessing implementation challenges, technical interpretations, industry-specific treatment of certain revenue contract types, and project status.

The Partnership is currently reviewing contracts for each revenue stream identified within each of our business segments. Through this process, the Partnership is evaluating potential changes in revenue recognition upon adoption of the revised guidance.

The Partnership is evaluating the potential information technology and internal control changes that will be required for adoption based on the findings of the contract review process.

The Partnership plans to provide internal training and awareness related to the revised guidance to the key stakeholders throughout the organization.

While the Partnership has tentatively concluded that the implementation of ASU 2014-09 will not have a material impact on the revenue recognition policies for a substantial number of contracts, management has identified several areas of potential impact through the contract review process currently underway, including accounting for non-cash consideration and the timing of revenue recognition with respect to deficiency payments in the crude oil pipeline services segment The Partnership is in the process of quantifying the impact of adoption, but cannot reasonably estimate the full impact of the standard until the industry reaches consensus on these issues. The Partnership is currently evaluating potential changes to disclosures based on the additional requirements prescribed by the standard. These new disclosures include information regarding the significant judgments used in evaluating when and how revenue is (or will be) recognized and data related to contract assets and liabilities. Additionally, the Partnership is evaluating the business processes, systems, and controls to ensure the accuracy and timeliness of the recognition and disclosure requirements under the new revenue guidance.

The Partnership will continue to conduct the contract review process throughout 2017 and, as a result, additional areas of impact may be identified. The Partnership expects to adopt the new standard on January 1, 2018, using the modified retrospective approach. This approach allows for applying the new standard to (i) all new contracts entered into after January 1, 2018, and (ii) all existing contracts for which all (or substantially all) of the revenue has not been recognized under legacy revenue guidance as of January 1, 2018, through a cumulative adjustment to equity. Consolidated revenues presented in the comparative financial statements for periods prior to January 1, 2018, would not be revised.

In November 2015, the FASB issued ASU 2015-17, “Income Taxes (Topic 740).” This update simplifies the presentation of deferred income taxes on the balance sheet. This update is effective for financial statements issued for annual periods beginning after December 15, 2016, includingand interim reporting periods within that reporting period. those fiscal years.

In March 2016, the FASB also issued ASU 2016-10, “Revenue from Contracts with Customers (Topic 606) Identifying Performance Obligations and Licensing.” This update offers guidance on identifying performance obligations and licensing in relation to ASU 2014-09, “Revenue from Contracts with Customers.” The effective date for the amendments in this update are the same as the effective date of ASU 2014-09. In May 2016, the FASB issued ASU 2016-12, “Revenue from Contracts with Customers (Topic 606) Narrow-Scope Improvements and Practical Expedients.”key information about leasing arrangements. This update is effective for financial statements issued in relation to ASU 2014-09, “Revenue from Contracts with Customers”for annual periods beginning after December 15, 2018, and is intended to reduce the potential for diversity if practice at initial application and also to reduce the cost and complexity of applying Topic 606 both at transition and on an ongoing basis. The effective date for the amendments in this update are the same as the effective date of ASU 2014-09.interim periods within those fiscal years. The Partnership is evaluating the impact of this guidance, which will be adopted beginning with the Partnership’s quarterly report for the period ending March 31, 2018.2019.

In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718).” This update is intended to simplify the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This update is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those fiscal years. The Partnership adopted this update in the three month period ending March 31, 2017, and there was no impact on the Partnership’s financial position, results of operations or cash flow.

In February 2017, the FASB issued ASU 2017-05, “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20).” This update clarifies the scope of Subtopic 610-20 and adds guidance for partial sales of nonfinancial assets. Subtopic 610-20, which was issued in May 2014 as a part of Accounting Standards Update No.


2014-09, Revenue from Contracts with Customers (Topic 606), provides guidance for recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. The amendments in ASU 2017-05 are effective for public entities for annual reporting periods beginning after December 15, 2017, and for interim periods within that reporting period. Early application is permitted for annual reporting periods beginning after December 15, 2016. The Partnership is evaluating the impact of this guidance,standard on us, which will be adopted beginning with the Partnership’s quarterly report for the period ending March 31, 2017.2018.

In June 2016,May 2017, the FASB issued ASU 2016-13, “Financial Instruments2017-09, “Compensation - Credit LossesStock Compensation (Topic 326) Measurement718) Scope of Credit Losses on Financial Instruments.Modification Accounting.” This update isprovides clarity and reduces both diversity in practice and cost and complexity when applying the guidance of Topic 718, Compensation - Stock Compensation, to provide financial statement users with more decision-useful information abouta change in the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The amendments in this Update replace the incurred loss impairment methodology in current GAAP with a

This update is effective for financial statements issued for annual periods beginning after December 15, 2019,2017, and interim periods within those fiscal years. The Partnership is evaluating the impact of this guidance, which will be adopted beginning with the Partnership’s quarterly report for the period ending March 31, 2020.2018.

Overview
 
We are a publicly traded master limited partnership with operations in twenty-fourtwenty-six states. We provide integrated terminalling, storage, gathering and transportation services for companies engaged in the production, distribution and marketing of crude oil and liquid asphalt cement.cement and crude oil.  We manage our operations through four operating segments: (i) asphalt terminalling services, (ii) crude oil terminalling and storage services, (iii) crude oil pipeline services and (iv) crude oil trucking and producer field services.  

Potential Impact of Recent Crude Oil Market Price Changes and Other Matters on Future Revenues

Since June of 2014, the market price of West Texas Intermediate crude oil has decreased by approximately 60%,fluctuated significantly from a peak of approximately $108 per barrel to a low of approximately $43$30 per barrel in(as of July of 2016. In addition,27, 2017, the price per barrel was approximately $49). Also, during the fourth quarter of 2014, the West Texas Intermediate crude oil forward price curve changed from a backwardated curve (in which the current crude oil price per barrel is higher than the future price per barrel and a premium is placed on delivering product to market and selling as soon as possible) to a contango curve (in which future prices are higher than current prices and a premium is placed on storing product and selling at a later time). In addition to changes in the price of crude oil and changes in the forward pricing curve, there has been significant volatility in the overall energy industry and specifically in publicly traded midstream energy partnerships. As a result, there are a number of trends that may impact our partnership in the near term. These include the market price for crude oil, decreased production in areas in which we serve, decreased demand for transportation capacity and an increased cost of capital. We expect these changes to have the following near-term impacts:

Asphalt Terminalling Services - Although there is no direct correlation between the price of crude oil and the price of asphalt, the asphalt industry tends to benefit from a lower crude oil price environment, strong economy and an increase in


infrastructure spend.investment. As a result, we do not expect the significant decreaserecent changes in the price of crude oil to significantly impact our asphalt terminalling services operating segment.

Crude Oil Terminalling and Storage Services - A contango crude oil curve tends to favor the crude oil storage business as crude oil marketers are incentivized to store crude oil during the current month and sell into the future month. In September 2014, we had approximately 4.8 million barrels of storage with contracts that had expired or would expire between September 30, 2014 and May 31, 2015. As a result of the decrease in the crude oil price and change in the crude oil futures pricing curve, weour weighted average storage rates increased from September 2014 to March 2016 and have been ablesince leveled out. We have approximately 1.9 million barrels of storage with contracts that expire during 2017. A change in the crude oil futures pricing curve from contango to renewbackwardated may impact our ability to recontract expiring contracts at average rates higher than those in place at September 30, 2014, and increase customer diversity byor the addition of two new customers, as a result ofrate upon which storage capacity leased by Vitol decreased from nearly two-thirds of our Cushing storage at September 30, 2014, to less than one-half beginning in the second quarter of 2015. The percentage of storage capacity leased by Vitol has remained consistent since the second quarter of 2015.they are recontracted.

Crude Oil Pipeline Services - We do not currently expect the recent crude oil price changes to have a significant impact on our Mid-Continent pipeline system as a portion of that capacity is contracted under a long-term throughput and deficiency agreement and volumes remained consistent throughout 2015. However, inIn late April 2016, as a precautionary measure we suspended service on a segment of our Mid-Continent pipeline system due to a discovery of a pipeline exposure caused by recent heavy rains and the erosion of a riverbed in southern Oklahoma. There was no damage to the pipepipeline and no loss of product. In the second quarter of 2016, we took action to mitigate the service suspension and worked with customers to divert volumes, and, in certain circumstances, transported volumes to a third-party pipeline system via truck. In addition, the term of the throughput and deficiency agreement on our Eagle North system expired at June 30, 2016, and, in July of 2016, we completed a connection of the southeastern most portion of our Mid-Continent pipeline system to our Eagle North system and concurrently reversed the Eagle North system. This enabled us to begin to recapture diverted volumes and deliver those barrels to Cushing, Oklahoma starting in July of 2016. As a result, we

We are currently operating one Oklahoma mainline system, which is a combination of both the Mid-Continent and Eagle PipelineNorth systems, instead of two separate systems.systems, providing us with a current capacity of approximately 20,000 to 25,000 barrels per day (“Bpd”). We continueare working to evaluaterestore service of the timing of and long-term repair necessary to allow us to operate two separate Oklahoma pipeline systems as well as the overall potential financial impact. The timing, cost and overall potential financial impact of re-establishing a second Oklahoma pipeline system is dependent onand expect to put the overall scopeline back in condensate service with a capacity of our condensate pipeline project, which20,000 Bpd at the end of 2017. The ability to fully utilize the capacity of these systems may be impacted by the market price of crude oil and producers’ decisions to increase or decrease production in the areas we continue to evaluate and will be dependent on customer demand and/or volume commitments.serve.

We have experienced a decrease in revenue on our East Texas pipeline system as a result of an overall decrease in production in the area and the expiration of an incentive tariff on a section of the system. As a result of the decrease in revenues and resulting decline in market values, we recognized non-cash impairment expenses of $12.6 million and $1.4 million related to our East Texas pipeline system and a portion of our Mid-Continent pipeline system, respectively, in the fourth quarter of 2015. In addition,2015 and an additional $2.3 million related to our East Texas system in Westthe fourth quarter of 2016. On April 18, 2017, we sold the East Texas pipeline. We received cash proceeds at closing of approximately $4.8 million and recorded a numbergain of new pipelines have been or are expected to be put into service, which will increase the amount of takeaway capacity and competition for the same or declining volumes of crude oil and may impact margins and future equity earnings from theless than $0.1 million.

On April 3, 2017, Advantage Pipeline, L.L.C. (“Advantage Pipeline”), in which we have aowned an approximate 30% equity ownership interest.interest, was acquired by a joint venture formed by affiliates of Plains All American Pipeline, L.P. and Noble Midstream Partners LP. We received cash proceeds at closing from the sale of our approximate 30% equity ownership interest in Advantage Pipeline of approximately $25.3 million and recorded a gain on the sale of the investment of $4.2 million. Approximately 10% of the gross sale proceeds are currently being held in escrow, subject to certain post-closing settlement terms and conditions. We expect to receive our approximately 30% pro rata portion of the net escrow proceeds, or approximately $2.5 million, by the end of 2017.

We also evaluated the current prospects ofThe Knight Warrior a previously announcedproject, the East Texas Eaglebine/Woodbine crude oil pipeline project, and have decided to not pursue developmentwas canceled during the second quarter of the project.  The Knight Warrior project is being canceled2016 due to continued low rig counts in the Eaglebine/Woodbine area coupled with lower production volumes, competing projects and the overall impact of the decreased market price of crude oil.  Consequently, shipper commitments related to the project one of which is a transportation agreement with Eaglebine Crude Oil Marketing LLC, which is 50% owned by Vitol (who also owns 50% of BKEP’s general partner), have been canceled. In connection with the cancellation of the shipper commitments, we evaluated the Knight Warrior project for impairment and recognized an impairment expense of $22.6 million during the three months endedin June 30, 2016.

Crude Oil Trucking and Producer Field Services - A backwardated crude oil curve tends to favor the crude oil transportation services business as crude oil marketers are incentivized to deliver crude oil to market and sell as soon as possible. When the crude oil market curve changed from a backwardated curve to a contango curve in the fourth quarter of 2014, coupled with a decrease in the absolute price of crude oil, transported volumes startedbegan decreasing. Throughout 2015, we experienced downward rate pressure in our trucking and producer field services business as producers and marketers attemptedWe continue to renegotiate service rates to preserve their operating margins in the changing market. In addition, during the second half of 2015, our West Texas operating margins and transported volumes were negatively impacted byexperience increased competition from transporters moving equipment from crude oil shale areas to West Texas, where crude oil volumes have remained relatively consistent, and by producers and marketers quickly pipe-connecting transported barrels. As a result, we decided to cease trucking barrels in West Texas and refocus our efforts on transporting barrels around our owned crude oil pipelines and storage assetsthis segment, which has resulted in Oklahoma and Kansas. In the fourth quarter of 2015, we recorded a restructuring charge of $1.6 million associated with our exit from West Texas, in addition to a non-cash impairment expense of $0.5 million associated with a write-down of


assets to their estimated net realizable value. See Note 3 to our unaudited condensed consolidated financial statements for additional detail regarding this restructuring expense.

Organic Projects vs. Acquisitions - In addition to the impacts above, we anticipate that a prolonged period of lower crude oil prices, a decrease in drilling and production volumes and increases in the cost of capital may change our bias from organic projects toward acquisitions with faster positive cash flows as opposed to organic projects that do not generate positive cash flow during their development. We plan to continue to develop projects organically, but do so considering production volumes, pricing and drilling activities in areas in which we operate.

Our Revenues 

Our revenues consist of (i) terminalling and storage revenues, (ii) gathering, transportation and producer field services revenues, (iii) product sales revenues and (iv) fuel surcharge revenues. For the three and six months ended June 30, 2016,2017, we derived approximately $5.5


recognized revenues of $13.5 million and $0.3$26.8 million, and duringrespectively, for services provided to Ergon. For the six months ended June 30, 2016,2017, we derived approximately $12.2recognized revenues of $0.3 million and $0.7 million of our revenues fromfor services we provided to Vitol and Advantage Pipeline L.L.C. (“Advantage Pipeline”), respectively, with thePipeline. The remainder of our services beingwas provided to unrelated third parties.

Terminalling and storage revenues consist of (i) storage service fees from actual storage used on a month-to-month basis; (ii) storage service fees resulting from short-term and long-term contracts for committed space that may or may not be utilized by the customer in a given month; and (iii) terminal throughput service charges to pump crude oil to connecting carriers or to deliver asphalt product out of our terminals. Terminal throughput service charges are recognized as the crude oil exits the terminal and is delivered to the connecting crude oil carrier or third-party terminal and as the asphalt product is delivered out of our terminal. Storage service revenues are recognized as the services are provided on a monthly basis. We earn terminalling and storage revenues in two of our segments: (i) asphalt terminalling services and (ii) crude oil terminalling and storage services.

We have leases and storage agreements with third party customers for all of our 4554 asphalt facilities.  The majority of the leases and storage agreements related to these facilities have terms that expire between the end of 2016 and the end of 2018.  We operate the asphalt facilities pursuant to the storage agreements, while our contract counterparties operate the asphalt facilities that are subject to the lease agreements.

As of July 28, 2016,27, 2017, we had approximately 5.86.0 million barrels of crude oil storage under service contracts with remaining terms ranging from 1one month to 1553 months, including 2.21.9 million barrels of crude oil storage contracts that expire in 2016.2017 and an additional 3.3 million barrels of crude oil contracts that expire in 2018. Storage contracts with Vitol represent 2.42.2 million barrels of crude oil storage capacity under contract. We are in negotiations to either extend contracts with existing customers or enter into new customer contracts for the storage capacity expiring in 2016;2017; however, there is no certainty that we will have success in contracting available capacity or that extended or new contracts will be at the same or similar rates as the expiring contracts. If we are unable to renew the majority of the expiring storage contracts,


we may experience lower utilization of our assets which could have a material adverse effect on our business, cash flows, ability to make distributions to our unitholders, the price of our common units, results of operations and ability to conduct our business.

Gathering and transportation services revenues consist of service fees recognized for the gathering of crude oil for our customers and the transportation of crude oil to refiners, to common carrier pipelines for ultimate delivery to refiners or to terminalling and storage facilities owned by us and others. Revenue for the gathering and transportation of crude oil is recognized when the service is performed and is based upon regulated and non-regulated tariff rates and the related transport volumes.  Producer field services revenue consists of a number of services ranging from gathering condensates from natural gas producers to hauling produced water to disposal wells.  Revenue for producer field services is recognized when the service is performed. We earn gathering and transportation revenues in two of our segments: (i) crude oil pipeline services and (ii) crude oil trucking and producer field services.
 
During the three months ended June 30, 2016,2017, we transported approximately 39,00023,000 barrels per day on our pipelines, which is a decrease of 29%41% compared to the three months ended June 30, 2015.2016. During the six months ended June 30, 20162017, we transported approximately 45,00025,000 barrels per day on our pipelines, which is a decrease of 8%44% compared to the six months ended June 30, 2015.2016. See Crude oil pipeline services segment within our results of operations discussion for additional detail. Vitol accounted for 15%61% and 30%15% of volumes transported in our pipelines in the three months ended June 30, 20162017 and 2015,2016, respectively. Vitol accounted for 24%56% and 33%24% of volumes transported in our pipelines in the six months ended June 30, 2017 and 2016, and 2015, respectively.

For the three months ended June 30, 2016,2017, we transported approximately 28,00022,000 barrels per day on our crude oil transport trucks, a decrease of 49%21% as compared to the three months ended June 30, 2015.2016. For the six months ended June 30, 2017, we transported approximately 22,000 barrels per day on our crude oil transport trucks, a decrease of 27% as compared to the six months ended June 30, 2016. Vitol accounted for approximately 29%55% and 45%29% of volumes transported by our crude oil transport trucks in the three months ended June 30, 2017 and 2016, and 2015, respectively. For the six months ended June 30, 2016, we transported approximately 30,000 barrels per day on our crude oil transport trucks, a decrease of 47% as compared to the six months ended June 30, 2015. Vitol accounted for approximately 30%50% and 44%30% of volumes transported by our crude oil transport trucks in the six months ended June 30, 2017 and 2016, respectively. The decrease in transported volumes is attributable to increased competition and 2015, respectively.lower crude oil production volume in the areas we serve.

Product sales revenues are comprised of (i) revenues recognized for the sale of crude oil to our customers that we purchase at production leases and (ii) revenue recognized in buy/sell transactions with our customers. Product sales revenue is recognized for products upon delivery and when the customer assumes the risks and rewards of ownership. We earn product sales revenue in our crude oil pipeline services operating segment.



Fuel surcharge revenues are comprised of revenues recognized for the reimbursement of fuel and power consumed to operate our asphalt product storage tanks and terminals.  We recognize fuel surcharge revenues in the period in which the related fuel and power expenses are incurred.

Our Expenses

Operating expenses decreasedincreased by 16% in 201614% for the six months ended June 30, 2017 as compared to 2015.the six months ended June 30, 2016. This is primarily a result of a decreasethe acquisition of the nine asphalt terminals from Ergon in compensation expenseOctober 2016. Decreases in general and fuel costsadministrative expenses for the six months ended June 30, 2017 as compared to the six months ended June 30, 2016 were primarily due to expenses incurred in 2016 related to the restructuring ofErgon Transactions (as defined in Note 1 to our trucking and field services operating segment initiated in the fourth quarter of 2015. General and administrative expenses alsounaudited condensed consolidated financial statements). Our interest expense decreased by 1% in 2016$1.3 million for the six months ended June 30, 2017 as compared to 2015. Our interest expense increased by 37% in 2016 as compared to 2015.the six months ended June 30, 2016. See Interest expense within our results of operations discussion for additional detail regarding the factors that contributed to the increasedecrease in interest expense in 2016.2017.

Income Taxes

As part of the process of preparing the unaudited condensed consolidated financial statements, we are required to estimate the federal and state income taxes in each of the jurisdictions in which our subsidiary that is taxed as a corporation operates. This process involves estimating the actual current tax exposure together with assessing temporary differences resulting from differing treatment of items, such as depreciation, for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included in our unaudited condensed consolidated balance sheets. We must then assess, using all available positive and negative evidence, the likelihood that the deferred tax assets will be recovered from future taxable income. Unless we believe that recovery is more likely than not, we must establish a valuation allowance. To the extent we establish a valuation allowance or increase or decrease this allowance in a period, we must include an expense or reduction of expense within the tax provisions in the unaudited condensed consolidated statements of operations.

Under ASC 740 – Accounting for Income Taxes, an enterprise must use judgment in considering the relative impact of negative and positive evidence. The weight given to the potential effect of negative and positive evidence should be commensurate with the extent to which it can be objectively verified. The more negative evidence that exists (a) the more


positive evidence is necessary and (b) the more difficult it is to support a conclusion that a valuation allowance is not needed for some portion or all of the deferred tax asset. Among the more significant types of evidence that we consider are:

taxable income projections in future years;
whether the carryforward period is so brief that it would limit realization of tax benefits;
future revenue and operating cost projections that will produce more than enough taxable income to realize the deferred tax asset based on existing service rates and cost structures; and
our earnings history exclusive of the loss that created the future deductible amount coupled with evidence indicating that the loss is an aberration rather than a continuing condition.

Based on the consideration of the above factors for our subsidiary that is taxed as a corporation for purposes of determining the likelihood of realizing the benefits of the deferred tax assets, we have provided a full valuation allowance against our deferred tax asset as of June 30, 20162017.

Distributions
 
The amount of distributions we pay and the decision to make any distribution is determined by the Board of Directors of our General Partnergeneral partner (the “Board”), which has broad discretion to establish cash reserves for the proper conduct of our business and for future distributions to our unitholders. In addition, our cash distribution policy is subject to restrictions on distributions under our credit facility. 

On July 18, 2016,2017, the Board approved a distribution of $0.17875 per preferred unit, or a total distribution of $5.4$6.3 million, for the quarter ending June 30, 2016.2017.  We will pay this distribution on the preferred units on August 12, 2016,14, 2017, to unitholders of record as of August 2, 2016.4, 2017.

In addition, on July 18, 2016,2017, the Board approved a cash distribution of $0.1450 per unit on our outstanding common units. The distribution will be paid on August 12, 2016,14, 2017, to unitholders of record on August 2, 2016.4, 2017. The distribution is for the three months ended June 30, 2016.2017. The total distribution to be paid is approximately $5.8$5.9 million, inclusive of $0.6 million related to the 3.8 million common units we issued in July 2016, with approximately $5.4$5.5 million


and $0.3 million paid to our common unitholders and general partner, respectively, and $0.1 million paid to holders of phantom and restricted units pursuant to awards granted under our long-term incentive plan.

Results of Operations

Non-GAAP Financial Measures
 
To supplement our financial information presented in accordance with GAAP, management uses additional measures that are known as “non-GAAP financial measures” in its evaluation of past performance and prospects for the future.  The primary measure used by management is segment operating margin, which includes revenues from related parties and external customers less operating expenses excluding depreciation and amortization.
 
Management believes that the presentation of such additional financial measures provides useful information to investors regarding our performance and results of operations because these measures, when used in conjunction with related GAAP financial measures, (i) provide additional information about our core operating performance and ability to generate and distribute cash flow, (ii) provide investors with the financial analytical framework upon which management bases financial, operational, compensation and planning decisions and (iii) present measurements that investors, rating agencies and debt holders have indicated are useful in assessing us and our results of operations. These additional financial measures are reconciled to the most directly comparable measures as reported in accordance with GAAP, and should be viewed in addition to, and not in lieu of, our unaudited condensed consolidated financial statements and footnotes.

For the three and six months ended June 30, 2016,2017, operating margin, excluding depreciation and amortization, increased in our crude oilasphalt terminalling and storage services and crude oil trucking and producer field services. Crude oil terminalling and storage services margin increasedsegment primarily as a result of increased rates under new contracts. Crude oil trucking and producer field services margin increased primarily due to a saleacquisitions of crude oil and lower operating expenses.eleven asphalt terminals in 2016. These increases were offset by lower operating margins in our asphalt terminalling services and crude oil pipeline servicesother segments. Asphalt terminalling services margin decreased due to contract renegotiation fees, which were partially offset by increased revenues on the three asphalt terminals acquired since May 2015. Crude oil pipeline services margin decreased due to suspended service on our Mid-Continent pipeline system beginning in April 2016 due to a discovery of a pipeline exposure caused by recent heavy rains and erosion of a river in southern Oklahoma.

For the six months ended June 30, 2016, operating margin, excluding depreciation and amortization, increased in our asphalt and crude oil terminalling and storage services segments asoperating margin decreased slightly due to a result of acquisitions of three asphalt terminals, annual contract escalations, and new crude oildecrease in market rates for short-term, monthly storage and terminalling contracts. These increases were offset by lower operating margins in our crude oil pipeline services and crude oil trucking and producer field services segments. The decrease in crude oil pipeline services margin resulted from the expirationsuspended service on our Mid-Continent pipeline system due to a discovery of an increased tariff that was being charged from June 2014 through May 2015 on certain barrels transported ona pipeline exposure in April 2016 as well as the sale of our East Texas pipeline system under a throughput and deficiency agreement. The tariff returned to a lower rate in June of 2015, which decreased the service revenues generated on the East Texas pipeline system by $4.7 million when comparing the six months ended June 30, 2016 to the same period in 2015. This was partially offset by $1.6 million in sales of crude oil arising from product loss allowances in the six months ended June 30, 2016.April 2017. Crude oil trucking and producer field services operating margin, excluding depreciation and amortization, decreased due to continued pressure on trucking and producer field service rates resulting from the decline in crude oil prices and a decrease in transported volumes.

The following is a discussion of items impacting asphalt terminalling services segment operating margin for the periods indicated:

Third partyOverall revenues decreased for the three months ended June 30, 2016, as compared to the three months ended June 30, 2015, primarily due to contract renegotiation fees that increased revenues by $2.3 million for 2015 as compared to 2016. This was partially offset by additional revenues on two asphalt terminalling facilities acquired in February 2016. Third party revenues increased for the six months ended June 30, 2016, as compared to the six months ended June 30, 2015, as a result of the acquisition of one asphalt terminalling facility in May 2015 and two asphalt terminalling facilities in February 2016 as well as annual contract fee escalations, which were partially offset by the contract renegotiation fees noted above.

Related party revenues are consistent for the three months ended June 30, 2016 and 2015. The variance in related party revenues for the six months ended June 30, 2016, compared to the same period in the prior year is primarily due to an additional storage tank being utilized by Vitol beginning in the the second quarter of 2015.

Operating expenseshave increased for the three and six months ended June 30, 2016,2017, as compared to the three and six months ended June 30, 2015,2016 primarily due primarily to the acquisition of nine asphalt facilities from Ergon in October 2016 in addition to two asphalt terminalling facilitiesterminals acquired in February 2016. This was partially offset by decreased maintenance2016 from unrelated third parties. Also in October 2016, Ergon acquired our general partner, resulting in all revenues generated from services provided to Ergon after October 5, 2016 being classified as related party revenues when they were previously classified as third party.

Operating expenses also increased for the three and repair expensessix months ended June 30, 2017, as compared to the three and six months ended June 30, 2016 due to the timing of maintenance projects.acquisitions noted above.

The following is a discussion of items impacting crude oil terminalling and storage segment operating margin for the periods indicated:

ThirdRevenues have moved from related party to third party due to Ergon acquiring our general partner in October 2016, at which time Vitol ceased to be a related party. Total revenues increased for the three and six months ended June 30, 2017 have decreased due to a decrease in market rates for short-term, monthly storage contracts and throughput fees as lower volumes were transferred in and out of our facilities.

Operating expenses for the three and six months ended June 30, 2017, decreased as compared to the three and six months ended June 30, 2016, compared to the same periodprimarily as a result of decreases in 2015 in connection with storage contract renewals. As contracts were expiring early in 2014, the rates at which we recontracted storage at the Cushing Interchange were impacted by a backwardated market for West Texas Intermediate crude which led to a decrease in average rates for the comparative three month periods. However, in the fourth quarter of 2014, the market for West Texas Intermediate crude oil returned to contango in which future prices are higher than current prices. This has increased demand for storage services at the Cushing Interchange, resulting in an upward trend in storage rates. Duemaintenance and repair expense due to the timing of the expiration of historical contracts and the execution of new storage contracts, the overall impact of the increase in storage rates began in the second quarter of 2015, and, as a result, revenues for the three months ended June 30, 2016 are consistent with the same period in 2015. As we negotiated new storage service contracts, we have been able to increase customer diversity by the addition of two new customers, as a result of which storage capacity leased by Vitol decreased from nearly two-thirds of our Cushing storage at September 30, 2014, to less than one-half beginning in the second quarter of 2015, resulting in an increase in third party revenue. The percentage of storage capacity leased by Vitol has remained consistent since the second quarter of 2015.

Related party revenues decreased for both periods due to the cancellation of the Operating and Maintenance agreement related to Vitol’s crude oil terminal located in Midland, Texas in the third quarter of 2015.routine tank maintenance.

As of July 28, 2016,27, 2017, we had approximately 5.86.0 million barrels of crude oil storage under service contracts with remaining terms of up to 1553 months, including 2.21.9 million barrels of crude oil storage contracts that expire in 2016. Storage contracts with Vitol represent 2.42017 and an additional 3.3 million barrels of crude oil storage capacity under contract.contracts that expire in 2018.

Operating expenses for the three and six months ended June 30, 2016, decreased as compared to the three and six months ended June 30, 2015, primarily as a result of decreases in utilities expense, as well as a decrease in compensation expense due to our no longer operating the Vitol Midland terminal.



Crude oil pipeline services segment

Our crude oil pipeline services segment operations include both service and product sales revenue. Service revenue generally consists of tariffs and other fees associated with transporting crude oil products on pipelines. Product sales revenue is comprised of (i) revenues recognized for the sale of crude oil to our customers that we purchase at production leases and (ii) revenue recognized in buy/sell transactions with our customers. Product sales revenue is recognized for products upon delivery and when the customer assumes the risks and rewards of ownership.

The following is a discussion of items impacting crude oil pipeline services segment operating margin for the periods indicated:

Service revenues decreasedRevenues have moved from related party to third party due to Ergon’s acquisition of our general partner in October 2016, at which time Vitol ceased to be a related party.

Included in product sales revenue for the three and six months ended June 30, 2016 compared to the same periodis $1.6 million in 2015 due to the expirationsales of an increased tariff that was being chargedcrude oil arising from June 2014 through May 2015 on certain barrels transported on our East Texas pipeline system under a throughput and deficiency agreement. The tariff returned to a lower rateaccumulated product-loss allowances (“PLA”). There were no such PLA sales in June of 2015, which decreased the service revenues generated on the East Texas pipeline system by $2.2 million and $4.7 million when comparing the three and six months ended June 30, 2016, respectively, to the same periods in 2015.2017.

In addition, in lateOn April 2016, as18, 2017, we sold the East Texas pipeline system. We received cash proceeds at closing of approximately $4.8 million and recorded a precautionary measure wegain of less than $0.1 million.

For the three and six months ended June 30, 2017, revenues were negatively impacted by the suspended service on our Mid-Continent pipeline system due to a discovery of a pipeline exposure caused by recent heavy rains and the erosion of a riverbed in southern Oklahoma.Oklahoma discovered in late April 2016. There was no damage to the pipe and no loss of product. In the second quarter of 2016, we took action to mitigate the service suspension and worked with customers to divert volumes, and, in certain circumstances, transported volumes to a third-party pipeline system via truck. In addition, the term of the throughput and deficiency agreement on our Eagle North system expired aton June 30, 2016, and in July of 2016 we completed a connection of the southeastern most portion of our Mid-Continent pipeline system to our Eagle North system and concurrently reversed the Eagle North system. This enabled us to recapture diverted volumes and deliver those barrels to Cushing, Oklahoma. As a result, weWe are currently operating one Oklahoma mainline system, which is a

In the first quarter of 2015, the refinery served by the Eagle North pipeline was undergoing maintenance, which temporarily decreased volumes transported on our pipeline.

Product sales revenues increased forFor the three and six months ended June 30, 2016, compared to the same period in 2015 due to our acquisition of the Red River pipeline in November 2015. In conjunction with our acquisition of the Red River pipeline, we began marketing crude oil that we purchase at production leases. Revenue from this activity is reflected in product sales revenue. In addition to the marketing revenue, we also had $1.6 million in sales of crude oil arising from product loss allowances in the three and six months ended June 30, 2016. There were no such sales of crude oil arising from product loss allowances in the three and six months ended June 30, 2015.

Cost of product sales incurred for the three and six months ended June 30, 2016, represent the cost of the marketed crude oil barrels transported on the Red River pipeline that was acquired in November 2015.

Operating2017, operating expenses have decreased primarily as a result of decreases in maintenance and repair and compensation expenses.expenses primarily due to decreased volumes transported on the Mid-Continent and East Texas pipeline systems. These decreases were partially offset by a leak remediation expense of approximately $0.1 million on the East Texas pipeline system during the three and six months ended June 30, 2017.

The following is a discussion of items impacting crude oil trucking and producer field services segment operating margin for the periods indicated:

Operating margin (excluding depreciationService revenues and amortization)operating expenses have decreased as a result of the continued low crude oil price environment and increased competition in the areas we serve. We continue to experience downward rate pressure in our trucking and producer field services business as producers and marketers attempt to renegotiate service rates to preserve their operating margins in the current market.

Revenues have moved from related party to third party due to Ergon’s acquisition of our general partner in October 2016, at which time Vitol ceased to be a related party.

Product sales revenues for the six months ended June 30, 2017 are the result of a crude oil sale in our field services business to a third party. Product sales revenues for the three and six months ended June 30, 2016 compared toare the three months ended June 30, 2015 due primarily to intersegment revenues earned from theresult of a crude oil sale of crude oilin our field services business to our crude oil pipeline services segment.

Operating margin (excluding depreciation and amortization) decreasedIncluded in operating expense for the three and six months ended June 30, 2016, compared2017 is approximately $0.1 million related to the six months ended June 30, 2015, primarily due to continued pressure on trucking and producer field service rates due to the decline inenvironmental remediation for a crude oil prices and a decrease in transported volumes.trucking station that we dismantled.

General and administrative expenses decreased to $4.7$8.9 million for the threesix months ended June 30, 2015. This increase is primarily due2017, compared to $0.5 million of transaction fees related to the Ergon transaction offset by decreases in compensation expense and insurance premiums due to decreased headcount. General and administrative expenses was consistent at $9.6 million for the six months ended June 30, 2016, compared2016. These decreases were primarily due to $0.5 million of expenses incurred in both the three and six months ended June 30, 2015. A decrease in compensation expense related to reduced headcount and a reduction in insurance premiums wasoffset by approximately $0.5 million of transaction fees2016, related to the Ergon Transactions. We expect incremental expenses of approximately $1.0 million to $1.5 million in the third quarter of 2016 in relation to the Ergon Transaction.

Asset impairment expense was $0.1 million and $22.8 million for the six months ended June 30, 2017 and 2016, respectively. During the second quarter of 2016, we recorded fixed asset impairment expense of $22.6 million due to an impairment recognized on the Knight Warrior a previously announced East Texas Eaglebine/Woodbine crude oil pipeline project, and have decided to not pursue development of the project. The Knight Warrior project is beingwas canceled due to continued low rig counts in the Eaglebine/Woodbine area coupled with lower production volumes, competing projects and the overall impact of the decreased market price of crude oil. Consequently, shipper commitments related to the project one of which is a transportation agreement with Eaglebine Crude Oil Marketing LLC, which is 50% owned by Vitol (who also owns 50% of BKEP’s general partner), have beenwere canceled. In connection with the cancellation of the shipper commitments, we evaluated the Knight Warrior project for impairment and recognized an impairment expense of $22.6 million during the three months ended June 30,second quarter of 2016.

Our Liquidity and Capital Resources
 
Cash flows from operations and our credit facility are our primary sources of liquidity. At June 30, 2016,2017, we had a working capital surplusdeficit of $4.8$1.5 million. This is primarily a function of our approach to cash management.

At June 30, 2016,2017, we had approximately $119.7$144.9 million of availability under our credit facility, although our ability to borrow such funds may be limited by the financial covenants in our credit facility.  As of June 30, 2016,and we could borrow up to $316.5$384.2 million, or an additional $26.2$79.1 million, under our credit facilityand still remain within our covenant restrictions. As of July 28, 2016,27, 2017, we have cash on hand of approximately $4.0 million and aggregate unused commitments under our revolving credit facility of approximately $147.7 million and cash on hand of approximately $23.0$147.9 million. Any incremental borrowings under our credit facility will be subject to covenant limitations.  The credit agreement willis scheduled to mature on June 28, 2018, and all amounts will become due and payable on such date.  See the caption “Debt” in Note 6 and “Credit Facility Amendment” in Note 17 to our unaudited condensed consolidated financial statements for further details.May 11, 2022. 

Capital Requirements. Our capital requirements consist of the following:
 


maintenance capital expenditures, which are capital expenditures made to maintain the existing integrity and operating capacity of our assets and related cash flows, further extending the useful lives of the assets; and
expansion capital expenditures, which are capital expenditures made to expand or to replace partially or fully depreciated assets or to expand the operating capacity or revenue of existing or new assets, whether through construction, acquisition or modification.



Expansion capital expenditures for organic growth projects, net of reimbursable expenditures of $0.3$0.1 million, totaled $5.2 million in the six months ended June 30, 2017, compared to $4.0 million in the six months ended June 30, 2016 compared to $11.4 million in the six months ended June 30, 2015.2016.  We currently expect our expansion capital expenditures for organic growth projects to be approximately $8.0 million to $9.0$10.0 million for all of 2016.2017.  Maintenance capital expenditures totaled $5.6$4.5 million, net of reimbursable expenditures of $1.7$0.5 million, in the six months ended June 30, 20162017, compared to $2.9$5.5 million in the six months ended June 30, 2015.2016.  We currently expect maintenance capital expenditures to be approximately $7.0$9.5 million to $8.0$10.5 million, net of reimbursable expenditures, for all of 2016.2017.

Our Ability to Grow Depends on Our Ability to Access External Expansion Capital. Our partnership agreement requires that we distribute all of our available cash to our unitholders. Available cash is reduced by cash reserves established by our General Partnergeneral partner to provide for the proper conduct of our business (including for future capital expenditures) and to comply with the provisions of our credit facility.  We may not grow as quickly as businesses that reinvest their available cash to expand ongoing operations because we distribute all of our available cash.

Item 3.    Quantitative and Qualitative Disclosures about Market Risk

We are exposed to market risk due to variable interest rates under our credit facility.

As of July 28, 201627, 2017, we had $251.0$300.6 million outstanding under our credit facility that was subject to a variable interest rate.  Borrowings under our credit agreement bear interest, at our option, at either the reserve adjusted eurodollar rate (as defined in the credit agreement) plus an applicable margin or the alternate base rate (the highest of the agent bank’s prime rate, the federal funds effective rate plus 0.5%, and the 30-day eurodollar rate plus 1%1.0%) plus an applicable margin. Interest rate swap agreements are used to manage a portion of the exposure related to changing interest rates by converting floating-rate debt to fixed-rate debt. In March 2014, we entered into twoAs of June 30, 2017 and December 31, 2016, the Partnership had three interest rate swap agreementsswaps with an aggregate notional valueamounts totaling $200.0 million to hedge the variability of $200.0 million. The first agreement became effective June 28, 2014, and matures on June 28, 2018.its LIBOR-based interest payments. Under the terms of the first interest rate swap agreement,settlement agreements, we pay a fixed raterates of 1.45%1.48%, 2.00% and receive one-month LIBOR with monthly settlement. The second agreement became effective January 28, 2015,1.97% on notional amounts of $100.0 million, $60.0 million and matures on January 28, 2019. Under the terms$40.0 million, respectively. On all of the second interest rate swap agreement,agreements, we pay a fixed rate of 1.97% and receive one-month LIBOR with monthly settlement. The fair market value of the interest rate swaps at June 30, 20162017 is a liability of $5.3$1.0 million and is recorded in long-term interest rate swap liabilities on the unaudited condensed consolidated balance sheets. The interest rate swaps do not receive hedge accounting treatment under ASC 815 - Derivatives and Hedging. Changes in the fair value of the interest rate swaps are recorded in interest expense in the unaudited condensed consolidated statements of operations.
 
During the six months ended June 30, 20162017, the weighted average interest rate under our credit agreement was 3.75%4.27%.

Changes in economic conditions could result in higher interest rates, thereby increasing our interest expense and reducing our funds available for capital investment, operations or distributions to our unitholders. Based on borrowings as of June 30, 2016,2017, the terms of our credit agreement, current interest rates and the effect of our interest rate swaps, an increase or decrease


of 100 basis points in the interest rate would result in increased or decreased annual interest expense of approximately $0.8 million and decreased annual interest expense of $0.4 million, respectively.$1.0 million.

Item 1.    Legal Proceedings.Proceedings

The information required by this item is included under the caption “Commitments and Contingencies” in Note 14 to our unaudited condensed consolidated financial statements and is incorporated herein by reference thereto.

Item 1A.    Risk Factors
 
See the risk factors set forth in Part I, Item 1A, of our Annual Report on Form 10-K for the year ended December 31, 2015, together with the additional risk factors set forth below.2016.
The Transactions may not be completed, and even if the Transactions are completed, we may fail to realize the benefits anticipated as a result of the Transactions.
The Transactions are expected to close on or before September 30, 2016, subject to a number of closing conditions, including clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. If these conditions are not satisfied or waived, the Transactions will not be consummated. There can be no assurances that the Transactions will be consummated or that the expected benefits of such acquisition will be realized. The closing of this offering is not conditioned on, nor is it a condition to, the consummation of the Transactions. If the Transactions are delayed, not consummated or consummated in a manner different than described herein, the price of our common units may decline. In addition, if the Transactions are not consummated, our management will have broad discretion in the application of the net proceeds of this offering. Accordingly, if you decide to purchase common units in this offering, you should be willing to do so whether or not we complete the Transactions.
If we are able to consummate the Transactions, such consummation would involve potential risks, including, without limitation, difficulties in integrating the acquired business, inefficiencies and unexpected costs and liabilities. If we consummate the Transactions and if these risks or other expected costs and liabilities were to materialize, any desired benefits of the Transactions may not be fully realized, if at all, and our future financial performance and results of operations could be negatively impacted.
Ergon may compete with us, which could adversely affect our existing business and limit our ability to acquire additional assets or businesses.
Upon consummation of the Transactions, Ergon will indirectly own our general partner. Neither our partnership agreement nor any other agreement with Ergon prohibits Ergon from owning assets or engaging in businesses that compete directly or indirectly with us. In addition, Ergon may acquire, construct or dispose of additional midstream or other assets in the future, without any obligation to offer us the opportunity to purchase or construct any of those assets. Ergon is privately owned company with a presence in over 12 countries worldwide, and is one of the largest asphalt emulsion marketers in the United States. Ergon has significantly greater resources and experience than we have, which factors may make it more difficult for us to compete with Ergon with respect to commercial activities as well as for acquisition candidates. As a result, competition from Ergon could adversely impact our results of operations and cash available for distribution.




Item 5.    Other Information

Iran Threat Reduction and Syria Human Rights Act Disclosure

Pursuant to Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012, which amended the Securities Exchange Act of 1934, an issuer is required to disclose in its annual or quarterly reports, as applicable, whether, during the reporting period, it or any of its affiliates knowingly engaged in certain activities, transactions or dealings relating to Iran or with individuals or entities designated pursuant to certain Executive Orders. Disclosure is generally required even where the activities, transactions or dealings were conducted in compliance with applicable laws and regulations.

The Partnership’s affiliates include members of the Vitol Group of companies (Vitol). Vitol is one of the world’s largest traders of oil and oil products. Following the relaxation of Iran related sanctions on January 16, 2016 an affiliate of the Partnership, Vitol Bahrain (VBA), has undertaken transactions with three Iranian state controlled companies namely the National Iranian Oil Company (NIOC),  the Persian Gulf Petrochemical Industry Trading Company (PGPI) and the Kharg Petrochemical Company (KPC). During the period from April 1, 2016 to June 30, 2016, VBA bought fuel oil and naphta from NIOC for a total cost of Emirati Dirham (AED) 739,928,844.63. During the same period, VBA also bought naphthas from (1) PGPI for a cost of AED 118,987,617.71 and (2) KPC for a cost of AED 39,396,444.55. In addition, during the same period, VBA sold gasoline to NIOC for a cost of AED 112,614,750.06. VBA does not calculate net profits on a per-customer transactional basis; however, Vitol estimates that the net profits attributable to the disclosed activity would not exceed 0.5% of Vitol’s annual profit. VBA anticipates that it will continue to do business with NIOC, PGPI and KPC provided that such activity continues to be permitted by applicable sanctions regimes.
