BUCKEYE PARTNERS, L.P.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION AND BASIS OF PRESENTATION

Organization

Buckeye Partners, L.P. is a publicly traded Delaware master limited partnership (“MLP”), and its limited partner units representing limited partnership interests (“LP Units”), are listed on the New York Stock Exchange under the ticker symbol “BPL.”  Buckeye GP LLC (“Buckeye GP”) is our general partner.  As used in these Notes to Unaudited Condensed Consolidated Financial Statements, “we,” “us,” “our” and “Buckeye” mean Buckeye Partners, L.P. and, where the context requires, include our subsidiaries.

We own and operate a diversified global network of integrated assets providing midstream logistic solutions, primarily consisting of the transportation, storage, processing and marketing of liquid petroleum products.  We are one of the largest independent liquid petroleum products pipeline operators in the United States in terms of volumes delivered, with approximately 6,000 miles of pipeline. We also use our service expertise to operate and/or maintain third-party pipelines and terminals and perform certain engineering and construction services for our customers. Our global terminal network comprises more than 115 liquid petroleum products terminals with aggregate tank capacity of over 118 million barrels across our portfolio of pipelines, inland terminals and marine terminals located primarily in key petroleum logistics hubs in the East Coast, Midwest and Gulf Coast regions of the United States as well as in the Caribbean.  Our terminal assets facilitate global flows of crude oil and refined petroleum products, offering our customers connectivity between supply areas and market centers through some of the world’s most important bulk liquid storage and blending hubs.  Our wholly-owned flagship marine terminal in The Bahamas, Buckeye Bahamas Hub Limited (“BBH”), is one of the largest marine crude oil and refined petroleum products storage facilities in the world and provides an array of logistics and blending services for the global flow of petroleum products. Our Gulf Coast regional hub, Buckeye Texas Partners LLC (“Buckeye Texas”), offers world-class marine terminalling, storage and processing capabilities. We are also a wholesale distributor of refined petroleum products in certain areas served by our pipelines and terminals.

Merger Agreement

On May 10, 2019, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Hercules Intermediate Holdings LLC, a Delaware limited liability company and an affiliate of IFM Global Infrastructure Fund (“Parent”), Hercules Merger Sub LLC, a Delaware limited liability company and a wholly owned subsidiary of Parent (“Merger Sub”), Buckeye Pipe Line Services Company, a Pennsylvania corporation (“ServiceCo”), and Buckeye GP. The Merger Agreement, which has been unanimously approved by the board of directors of Buckeye GP (the “Board”) on our behalf, provides for the merger of Merger Sub with and into Buckeye (the “Merger”), with Buckeye surviving the Merger as a wholly owned subsidiary of Parent. After the Merger, Buckeye’s LP Units will cease to be publicly traded.

Subject to the terms and conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each of our issued and outstanding LP Units (other than LP Units owned immediately prior to the Effective Time by us, by Parent or any of its affiliates or under certain circumstances by ServiceCo), will be converted into the right to receive $41.50 in cash per LP Unit (the “Merger Consideration”), without interest.

Completion of the Merger is subject to customary closing conditions, including unitholder and certain regulatory approvals. On July 31, 2019, the Merger Agreement and the transactions contemplated thereby were approved by the affirmative vote of the holders of a majority of the outstanding LP Units entitled to vote thereon. We expect the Merger to close during the fourth quarter of 2019.

For more information regarding the Merger and the Merger Agreement, please see our Form 8-K filed with the U.S. Securities and Exchange Commission (“SEC”) on May 10, 2019 and our Schedule 14A filed with the SEC on June 25, 2019, as supplemented by the Form 8-K we filed with the SEC on July 22, 2019.

Basis of Presentation and Principles of Consolidation

The unaudited condensed consolidated financial statements and the accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the rules of the SEC.  Accordingly, our financial statements reflect all normal and recurring adjustments that are, in the opinion of management, necessary for a fair presentation of our results of operations for the interim periods.  The unaudited condensed consolidated financial statements include the accounts of our subsidiaries controlled by us and variable interest entities of which we are the primary beneficiary. Intercompany transactions are eliminated in consolidation.

The preparation of consolidated financial statements in conformity with GAAP requires our management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses during the reporting period and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Estimates and assumptions about future events and their effects cannot be made with certainty.  Estimates may change as new events occur, when additional information becomes available and if our operating environment changes. Actual results could differ from our estimates.

We believe that the disclosures in these unaudited condensed consolidated financial statements are adequate to make the information presented not misleading.  These interim financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2018.

Recently Adopted Accounting Standards

Derivatives and Hedging. Effective January 1, 2019, we adopted Accounting Standards Update (“ASU”) 2017-12, which amends and simplifies the existing standard in order to improve the financial reporting of hedging relationships to better align risk management activities in financial statements and make targeted improvements to simplify the application of the current standard related to the assessment of hedge effectiveness. In October 2018, the Financial Accounting Standards Board (“FASB”) issued ASU 2018-16, which includes the Overnight Index Swap Rate based on Secured Overnight Financing Rate as a U.S. benchmark interest rate for hedge accounting purposes under Accounting Standards Codification (“ASC”) Topic 815, Derivatives and Hedging. The adoption of this standard did not have a material impact on our unaudited condensed consolidated financial statements and disclosures.

Leases. Effective January 1, 2019, we adopted ASC Topic 842, Leases (“ASC 842”), applying the modified retrospective transition method. We applied the transition provision for ASC 842 at our adoption date instead of at the earliest comparative period presented in our financial statements and, therefore, we recognized and measured leases existing at January 1, 2019, but without retrospective application. ASC 842 requires lessees to recognize a right-of-use (“ROU”) lease asset and a lease liability on the balance sheet for leases with lease terms greater than twelve months. ASC 842 also requires enhanced disclosures regarding the amount, timing and uncertainty of cash flows arising from leases. The most significant impact was the recognition of ROU lease assets and lease liabilities for operating leases on our unaudited condensed consolidated balance sheet along with certain incremental disclosures. No impact was recorded to the income statement or beginning retained earnings upon our adoption of ASC 842. See Note 9 - Leases for further discussion.

Improvements to Nonemployee Share-Based Payment Accounting. Effective January 1, 2019, we adopted ASU 2018-07, which conformed the current nonemployee share-based accounting with employee share-based accounting. The adoption of this standard did not have a material impact on our unaudited condensed consolidated financial statements and disclosures.

Recent Accounting Standards Not Yet Adopted

Codification Improvements. In April 2019, the FASB issued ASU 2019-04, which clarifies certain aspects of accounting for credit losses, hedging activities, and financial instruments (addressed by ASUs 2016-13, 2017-12, and 2016-01, respectively). The amendments clarify the scope of the credit losses standard (ASU 2016-13) and address issues related to accrued interest receivable balances, recoveries, variable interest rates and prepayments. The amendments on recognizing and measuring financial instruments (ASU 2016-01), address the scope of the guidance, the requirement for remeasurement under ASC 820 when using the measurement alternative, certain disclosure requirements and which equity securities have to be remeasured at historical exchange rates. The amendments to the credit losses and hedging standards have the same effective dates as those standards, unless an entity has already adopted the standards. The amendments to the recognition and measurement guidance are effective for fiscal years beginning after December 15, 2019. Early adoption is permitted. We adopted the amendments related to hedging and financial instruments effective June 30, 2019, which did not have an impact on our unaudited condensed consolidated financial statements. We expect to adopt the amendments related to credit losses concurrently with the adoption of ASU 2016-13.

Collaborative Arrangements. In November 2018, the FASB issued ASU 2018-18, which clarifies whether certain transactions between collaborative arrangement participants should be accounted for as revenue under ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). The new standard also provides more comparability in the presentation of revenue for certain transactions between collaborative arrangement participants. The standard is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, with early adoption permitted. The standard should be applied retrospectively to the date of initial application of ASC 606. We expect to adopt this standard effective January 1, 2020 and are currently evaluating the impact that it will have on our consolidated financial statements and disclosures.

Targeted Improvements to Related Party Guidance for Variable Interest Entities. In October 2018, the FASB issued ASU 2018-17 that changes the standard for determining whether a decision-making fee is a variable interest. The standard provides that indirect interests held through related parties under common control will be considered on a proportional basis when determining whether certain decision-making fees are variable interests. The standard is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, with early adoption permitted. The standard should be applied retrospectively, with a cumulative effect adjustment to retained earnings. We expect to adopt this standard effective January 1, 2020 and are currently evaluating the impact that it will have on our consolidated financial statements and disclosures.

Cloud Computing Arrangements. In August 2018, the FASB issued ASU 2018-15, which aligns a customer’s accounting for capitalizing implementation costs in a cloud computing service arrangement that is hosted by the vendor with the requirements for capitalizing implementation costs incurred to develop or obtain an internal-use software license. The standard is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, with early adoption permitted. The standard can be applied prospectively or retrospectively. We expect to adopt this standard effective January 1, 2020 and are currently evaluating the impact that it will have on our consolidated financial statements and disclosures.

Changes to the Disclosure Requirements for Defined Benefit Plans. In August 2018, the FASB issued ASU 2018-14, which amends the existing standard on disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The new standard is effective for fiscal years ending after December 15, 2020, with early adoption permitted. The new standard requires retrospective application. We expect to adopt this standard effective January 1, 2021 and are currently evaluating the impact that it will have on our disclosures.

Changes to the Disclosure Requirements for Fair Value Measurement. In August 2018, the FASB issued ASU 2018-13, which amends the existing standard on disclosure requirements for fair value measurements. The new standard is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, with early adoption permitted. The new standard requires prospective application on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty. The effects of other amendments must be applied retrospectively to all periods presented. We expect to adopt this standard effective January 1, 2020 and are currently evaluating the impact that it will have on our disclosures.

9

Measurement of Credit Losses on Financial Instruments.  In June 2016, the FASB issued ASU 2016-13, which replaces the current incurred loss impairment method with a method that reflects expected credit losses on financial instruments. In November 2018, the FASB issued update ASU 2018-19 that clarifies the scope of the standard in the amendments in ASU 2016-13. In May 2019, the FASB issued ASU 2019-05, which provides entities with an option to irrevocably elect the fair value option for certain financial instruments. The new standard is effective as of January 1, 2020, and early adoption is permitted as of January 1, 2019. We expect to adopt this standard effective January 1, 2020 and are currently evaluating the impact that the adoption of this standard will have on our consolidated financial statements and disclosures.

2. REVENUE

The majority of our service-based revenue is derived from fee-based transportation, terminalling, and storage services that we provide to our customers. We also generate revenue from the marketing and sale of petroleum products. We recognize revenues from customer fees for services rendered or by selling petroleum products. Under ASC 606, we recognize revenue over time or at a point in time, depending on the nature of the performance obligations contained in the respective contract with our customer. A performance obligation is a promise in a contract to transfer goods or services to the customer. The contract transaction price is allocated to each performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. In certain situations, we recognize revenue pursuant to accounting standards other than ASC 606. These situations primarily relate to leases and derivatives. We have appropriately applied the guidance in ASC Topic 340-40, Other Assets and Deferred Costs: Contracts with Customers, for determining whether to capitalize costs to fulfill a contract.

Contract Balances

At June 30, 2019 and December 31, 2018, receivables from contracts with customers was $204.2 million and $199.3 million, respectively. The following table presents the activity in our contract assets and contract liabilities (in thousands):

	Six Months Ended June 30,
	2019			2018
Contract Assets:
Balance as of January 1	$	16,989		$	13,999
Additions	17,133			25,633
Transfers to accounts receivable	(16,890		)	(13,751		)
Balance as of June 30	$	17,232		$	25,881
Contract Liabilities:
Balance as of January 1	$	(26,999	)	$	(15,778	)
Additions	(18,654		)	(18,184		)
Transfers to revenues(1)	12,403			6,586
Balance as of June 30	$	(33,250	)	$	(27,376	)

⁽¹⁾ For the three months ended June 30, 2019 and 2018, $0.8 million and $1.0 million, respectively, related to contract liabilities were transferred to revenue.

Contract assets and liabilities are included in Prepaid and other current assets and Other non-current liabilities, respectively, with the current portion of contract liabilities included in Accrued and other current liabilities, on our unaudited condensed consolidated balance sheets.

The following table includes estimated revenue associated with contractual commitments in place related to future performance obligations as of the end of the reporting period, which are expected to be recognized in revenue in the specified periods (in thousands):

	Revenue from Contracts with Customers		Revenue from Leases		Total
Remainder of 2019	$	197,741	$	114,522	$	312,263
2020	240,599		233,800		474,399
2021	152,116		206,213		358,329
2022	73,399		141,156		214,555
2023	67,108		27,153		94,261
Thereafter	304,739		24,283		329,022
Total	$	1,035,702	$	747,127	$	1,782,829

Our contractually committed revenue disclosure, for purposes of the tabular presentation above, excludes estimates of variable rate escalation clauses in our contracts with customers and is generally limited to our contracts with fixed pricing and minimum volume components. Our contractually committed revenue disclosure generally excludes remaining performance obligations on contracts with index-based pricing or variable volume attributes.

Lessor

We account for certain customer contracts for tolling, storage, and pipeline transportation services as leases in which we are the lessor. Accordingly, such revenues are presented separately in the revenue disaggregation tables in Note 17 - Business Segments.

As of June 30, 2019, assets recorded under revenue operating leases were $241.2 million and accumulated depreciation associated with operating leases was $31.7 million. Depreciation expense was $0.9 million for both of the three months ended June 30, 2019 and 2018 and $1.8 million for both of the six months ended June 30, 2019 and 2018. These assets primarily consist of our pipelines and terminals, docks and processing facilities.

We determined the contracts referenced above contain leases because their commercial provisions convey to the customers the right to effectively control the use of the underlying identified property and equipment assets through the right to obtain substantially all of the economic benefit from the use of the assets and the right to direct the use of these assets, despite our continued operatorship of the assets. Our lessor lease population is classified as revenue operating leases and does not currently have any material sales-type or financing leases. None of these customers are related parties. We have lease contracts with lease and non-lease components, which we account for separately.

Our lessor leases do not have variable minimum lease payments; however, the lease payments under these contracts are subject to additional revenues, correlated only to excess product volumes processed, stored, or transported. Certain of our leases include one or more customer options to renew the lease term beyond the initial term of the agreement. Some of our lease terms also include the option for our customers to extend or terminate the lease. Following the end of the lease term, control of the use of these assets reverts to us, and considering our continued ownership of the assets, as well as the assets’ remaining useful lives, we have the ability to seek further commercial opportunities to derive revenue from these assets.

As noted above, we operate these assets for customers’ benefit during the lease period and upon contract expiration, we retain ownership and control of the use of these assets. Accordingly, we have the ability to monitor the residual value of these assets. Generally, the lease period is only a small portion of the economic life of the asset under lease.

3. ACQUISITIONS, INVESTMENTS AND DISPOSITIONS

2019 Transaction

VTTI Divestiture

In January 2019, we completed the sale of our 50% equity interest in VTTI B.V. (“VTTI”) for approximately $975.0 million, excluding transaction costs of approximately $4.0 million incurred in 2019.

2018 Transactions

Domestic Asset Divestiture

On December 17, 2018, we sold certain domestic pipeline and terminal assets, which included (i) our jet fuel pipeline from Port Everglades, Florida to Ft. Lauderdale-Hollywood International Airport and Miami International Airport; (ii) our pipelines and terminal facilities serving Reno-Tahoe International Airport, San Diego International Airport, and the Federal Express Corporation terminal at the Memphis International Airport; and (iii) our refined petroleum product terminals in Sacramento, California and Stockton, California. The final payment of $10.0 million was received in June 2019.

South Texas Transactions

In April 2018, as part of our strategy to serve the volume growth in crude oil and related products from the Permian Basin, we expanded our marine terminal presence in Corpus Christi, Texas, through the following transactions: (i) acquired our business partner’s 20% interest in our Buckeye Texas consolidated subsidiary for $210 million, which was accounted for as an equity transaction, representing the acquisition of a non-controlling interest, and (ii) formed a joint venture with Phillips 66 Partners LP (“Phillips 66 Partners”) and Gray Oak Gateway Holdings (“Marathon”), a subsidiary of Marathon Petroleum Corporation, to develop a new deep-water, open-access marine terminal in Ingleside, Texas at the mouth of Corpus Christi Bay (“STG Terminal”).

STG Terminal will be constructed and operated by us. We continue to secure additional minimum volume throughput commitments and storage contracts from customers. The initial scope of this project has now increased from 3.4 million barrels of storage to approximately 7.0 million barrels, based on current contracted throughput and storage volumes, and includes two deep-water vessel docks capable of berthing very large crude carrier tankers. Our construction plan also includes connectivity to multiple pipelines delivering volumes into the Corpus Christi market from the growing Permian Basin production and other sources.

STG Terminal is expected to commence and ramp up operations by mid-2020 and is supported by long-term minimum volume throughput commitments and storage contracts from credit-worthy customers, including our joint-venture partners. We own a 50% interest in STG Terminal, and Phillips 66 Partners and Marathon each own a 25% interest. To date, our net investment is $72.5 million, including $31.8 million of net contributions during the six months ended June 30, 2019. We account for our interest in STG Terminal, which is included in our Global Marine Terminals segment, using the equity method of accounting.

4. COMMITMENTS AND CONTINGENCIES

Claims and Legal Proceedings

In the ordinary course of business, we are involved in various claims and legal proceedings, some of which are covered by insurance.  We are generally unable to predict the timing or outcome of these claims and proceedings.  Based upon our evaluation of existing claims and proceedings and the probability of losses resulting from such contingencies, we have accrued certain amounts relating to such claims and proceedings, none of which are considered material.

Unitholder Litigation

On June 13, 2019, a purported unitholder of Buckeye filed a complaint in a putative class action in the United States District Court for the Southern District of Texas, Houston Division, captioned Harry Curtis, individually and on behalf of all others similarly situated, v. Buckeye Partners, L.P., et al., Case No. 4:19-cv-2147 (the “Curtis Action”). On June 18, 2019, a purported unitholder of Buckeye filed a complaint in a putative class action in the United States District Court for the District of Delaware, captioned Michael Kent, individually and on behalf of all others similarly situated, v. Buckeye Partners, L.P., et al., Case No. 1:19-cv-01128 (the “Kent Action”). On June 19, 2019, a purported unitholder of Buckeye filed a complaint in the United States District Court for the Southern District of New York, captioned John Greer v. Buckeye Partners, L.P., et al., Case No. 1:19-cv-05741 (the “Greer Action”). On June 20, 2019, a purported unitholder of Buckeye filed a complaint in the United States District Court for the Southern District of New York, captioned Anthony Luers v. Buckeye Partners, L.P., et al., Case No. 1:19-cv-05767 (the “Luers Action”). On June 26, 2019, a purported unitholder of Buckeye filed a complaint in the United States District Court for the District of Delaware, captioned Michael Weston, individually and on behalf of all others similarly situated, v. Buckeye Partners, L.P., et al., Case No. 1:19-cv-01208 (the “Weston Action”). On June 26, 2019, a purported unitholder of Buckeye filed a complaint in the United States District Court for the Southern District of New York, captioned Heather McManus, individually and on behalf of all others similarly situated, v. Buckeye Partners, L.P., et al., Case No. 1:19-cv-06000 (the “McManus Action”). On June 28, 2019, a purported unitholder of Buckeye filed a complaint in the United States District Court for the Southern District of New York, captioned John Ingalls, individually and on behalf of all others similarly situated, v. Buckeye Partners, L.P., et al., Case No. 1:19-cv-06098 (the “Ingalls Action”). On June 28, 2019, a purported unitholder of Buckeye filed a complaint in the United States District Court for the District of Delaware, captioned Michael Riss, on behalf of himself and all others similarly situated, v. Buckeye Partners, L.P., et al., Case No. 1:19-cv-01241 (the “Riss Action” and, together with the Curtis Action, the Kent Action, the Greer Action, the Luers Action, the Weston Action, the McManus Action and the Ingalls Action, the “Federal Merger Litigation”). On June 28, 2019, Buckeye also received a joint demand letter from the plaintiffs of each of the Curtis Action, the Kent Action and the Greer Action reiterating the claims contained in each of those actions. On July 18, 2019, the Greer Action, the Luers Action, the McManus Action and the Ingalls Action were transferred to the United States District Court for Southern District of Texas, Houston. These cases are now docketed as Case No. 4:19-cv-02648, 4:19-cv-02647, 4:19-cv-02644 and 4:19-cv-02645, respectively.

The Curtis Action alleges, among other things, that in pursuing the Merger, the Board breached its express and implied contractual duties pursuant to Buckeye’s limited partnership agreement and its fiduciary duties to Buckeye’s unitholders in agreeing to enter into the Merger Agreement by means of an allegedly unfair process and for an allegedly unfair price. The Curtis Action, the Kent Action, the Greer Action, the Luers Action, the Weston Action and the McManus Action each further alleges that (i) Buckeye’s preliminary proxy statement, filed with the SEC on June 7, 2019 (the “Preliminary Proxy Statement”), omits material information with respect to the Merger, rendering it false and misleading and, as a result, that Buckeye and the members of the Board violated Section 14(a) of the Exchange Act, and Rule 14a-9 promulgated thereunder, and (ii) the members of the Board, as alleged control persons of Buckeye, violated Section 20(a) of the Exchange Act in connection with the filing of the allegedly materially deficient Preliminary Proxy Statement.

The Ingalls Action and the Riss Action each alleges that (i) Buckeye’s definitive proxy statement, filed with the SEC on June 25, 2019 (the “Proxy Statement”), omits material information with respect to the Merger, rendering it false and misleading and, as a result, that Buckeye and the members of the Board violated Section 14(a) of the Exchange Act, and Rule 14a-9 promulgated thereunder, and (ii) the members of the Board, as alleged control persons of Buckeye, violated Section 20(a) of the Exchange Act in connection with the filing of the allegedly materially deficient Proxy Statement.

The Curtis Action seeks, among other things, to enjoin the Merger, the disclosure of all material information concerning the Merger, an order rescinding the consummation of the Merger or an award of rescissory damages (in the event the Merger is consummated), an award of damages and an award of attorneys’ and experts’ fees and expenses.

The Kent Action and the Greer Action each seeks, among other things, to enjoin the Merger, an order rescinding the consummation of the Merger or an award of rescissory damages (in the event the Merger is consummated), an order directing that the Board disseminate a proxy statement that does not contain any untrue statements of material fact and that states all material facts required or necessary to make the statements contained therein not misleading, a declaration that the defendants violated Sections 14(a) and/or 20(a) of the Exchange Act, as well as Rule 14a-9 promulgated thereunder, and an award of attorneys’ and experts’ fees and expenses.

13

The Luers Action and the Ingalls Action each seeks, among other things, to enjoin the Merger until disclosure of the allegedly omitted material information identified in the Luers Action and the Ingalls Action, respectively, is provided, an order rescinding the Merger Agreement or any of the terms thereof or an award of rescissory damages (in the event the Merger is consummated), an award of damages and an award of attorneys’ and experts’ fees and expenses.

The Weston Action seeks, among other things, to enjoin the unitholder vote on the Merger or the consummation of the Merger until disclosure of the allegedly omitted material information identified in the Weston Action is provided, an order directing defendants to account for all damages sustained, an award of damages and an award of attorneys’ and experts’ fees and expenses.

The McManus Action seeks, among other things, to enjoin the consummation of the Merger, an order directing that the Board disseminate an amendment to the Preliminary Proxy Statement that does not contain any untrue statements of material fact and that states all material facts required or necessary to make the statements contained therein not misleading, an order directing defendants to account for all damages sustained and an award of attorneys’ and experts’ fees and expenses.

The Riss Action seeks, among other things, to enjoin the Merger until disclosure of the allegedly omitted material information identified in the Riss Action is provided, an order rescinding the Merger Agreement or any of the terms thereof or an award of rescissory damages (in the event the Merger is consummated), a declaration that the defendants violated Sections 14(a) and/or 20(a) of the Exchange Act, as well as Rule 14a-9 promulgated thereunder, and an award of attorneys’ and experts’ fees and expenses.

Buckeye believes that each of the Federal Merger Litigation is without merit and no supplemental disclosure is required under applicable law. However, in order to avoid the risk of the Federal Merger Litigation delaying or adversely affecting the Merger and to minimize the costs, risks and uncertainties inherent in litigation, and without admitting any liability or wrongdoing, on July 22, 2019, Buckeye filed with the SEC a Current Report on Form 8-K and a Schedule 14A supplementing certain of the allegedly misleading proxy statement disclosures identified in the Federal Merger Litigation. Each plaintiff agreed that the disclosure contained in the Current Report on Form 8-K and Schedule 14A mooted his or her disclosure claims.

It is possible that additional, similar complaints may be filed or the complaints described above may be amended. If this occurs, Buckeye does not intend to announce the filing of each additional, similar complaint or any amended complaint.

On June 14, 2019, Buckeye also received a demand letter from Walter E. Ryan Jr. (“Mr. Ryan”), a purported unitholder of Buckeye, requesting access to certain books and records of Buckeye to investigate possible mismanagement and/or breaches of fiduciary duty by the Board in connection with the Merger (the “Ryan Demand Letter”). On June 21, 2019, Buckeye responded to the Ryan Demand Letter denying the requests and allegations contained therein. On July 2, 2019, Buckeye received a revised demand letter from Mr. Ryan, which reiterated the demands contained in the Ryan Demand Letter (the “Revised Ryan Demand Letter”). On July 10, 2019, Buckeye responded to the Revised Ryan Demand Letter again denying the requests and allegations contained therein.

Environmental Contingencies

At June 30, 2019 and December 31, 2018, we had $35.5 million and $39.0 million, respectively, of environmental remediation liabilities.  Costs ultimately incurred may be in excess of our estimates, which may have a material impact on our financial condition, results of operations or cash flows.  At June 30, 2019 and December 31, 2018, we had $3.9 million and $4.2 million, respectively, of receivables related to these environmental remediation liabilities covered by insurance or third-party claims.

9. LEASES

Lessee

We have entered into certain agreements to use property, plant and equipment, including office space, equipment and land, which qualify as leases. ROU lease assets and liabilities associated with leases with an initial term of twelve months or less are not recorded on the balance sheet. Operating leases are included in Other non-current assets and Other non-current liabilities on our unaudited condensed consolidated balance sheet as of June 30, 2019, with the current portion of such liabilities being included in Accrued and other current liabilities. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the expected term of the lease at the commencement date including, as applicable, renewal periods when we have the option to extend and it is reasonably certain we will do so. As most of our leases do not provide an explicit interest rate, we use an applicable implicit incremental borrowing rate, based on the information available at the commencement date, in determining the present value of future payments. We give consideration to our borrowing rates based on our credit rating as well as secured and unsecured debt instruments with similar characteristics when calculating our incremental borrowing rates. We do not currently have any material financing leases. The operating lease ROU asset also includes lease payments made as of the commencement date and excludes lease incentives and initial direct costs. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. At this time, our lease population does not have either variable lease payments or residual value guarantees that would materially impact the ROU asset and liability valuation. Additionally, we do not have any sublease arrangements or lease transactions with related parties.

We have lessee agreements with lease and non-lease components, which are generally accounted for separately. For certain leases, we account for the lease and non-lease components as a single lease component based on the election of the practical expedient to not separate lease components from non-lease components related to the following classes of assets: (i) buildings and leasehold improvements; (ii) jetties, subsea pipeline and docks; (iii) pipelines and terminals; and (iv) vehicle, equipment and office furnishings. ASC 842 permits the lessee to account for its leases at a portfolio level provided that the resulting accounting would not differ materially from accounting at the individual lease level. We have applied the portfolio approach to certain equipment-type and vehicle leases in accounting for the operating lease ROU assets and liabilities. We also elected the package of practical expedients available upon adoption, including: (i) not to reassess whether any expired or existing contracts contain leases and lease classification for such leases, as well as initial direct costs for any existing leases; (ii) not to apply the provisions of ASU 2016-02 to land easements that existed or expired before adoption and that were not previously accounted for as leases under the previous lease standard in ASC Topic 840, Leases; (iii) to use hindsight in determining the lease term and in assessing impairment of our ROU lease assets; and (iv) not to apply provisions of ASU 2016-02 to short-term leases.

The operating lease costs for the three months ended June 30, 2019 and 2018 were $8.0 million and $8.1 million, respectively, including $1.2 million and $2.3 million of short-term operating lease costs for the respective periods. The operating lease costs for the six months ended June 30, 2019 and 2018 were $16.4 million and $16.2 million, respectively, including $3.5 million and $5.2 million of short-term operating lease costs for the respective periods.

11. LONG-TERM DEBT

Extinguishment of Debt

In January 2018, we repaid in full the $300.0 million principal amount outstanding under our 6.050% notes.

In January 2019, we repaid in full the $250.0 million variable-rate Term Loan due September 30, 2019 (the “Term Loan”), using proceeds from the VTTI sale transaction.

In February 2019, we repaid in full the $275.0 million principal amount outstanding under our 5.500% notes, using proceeds from the VTTI sale transaction as well as borrowings under our Credit Facility.

As a result of the 2019 retirements, we incurred a $4.0 million loss on early extinguishment of debt, consisting of a $3.6 million make-whole payment related to the 5.500% notes and unamortized financing costs of $0.4 million included in Other expense, net, on our unaudited condensed consolidated statements of operations.

Notes Offerings

In January 2018, we issued $400.0 million of junior subordinated notes (“Junior Notes”) maturing on January 22, 2078, which are redeemable at Buckeye’s option, in whole or in part, on or after January 22, 2023. The Junior Notes bear interest at a fixed rate of 6.375% per year up to, but not including, January 22, 2023. From January 22, 2023, the Junior Notes will bear interest at a floating rate based on the Three-Month London Interbank Offered Rate (“LIBOR”) plus 4.02%, reset quarterly. Total proceeds from this offering, after underwriting fees, expenses, and debt issuance costs, were $394.9 million. We used the net proceeds from this offering to reduce indebtedness outstanding under our $1.5 billion revolving Credit Facility with SunTrust Bank (the “Credit Facility”) and for general partnership purposes.

18

Credit Facility

At June 30, 2019, we had a $170.3 million outstanding balance under the Credit Facility, $109.8 million of which is classified as current. The weighted average interest rate for borrowings under the Credit Facility was 4.0% during the six months ended June 30, 2019.

12. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

We are exposed to financial market risks, including changes in interest rates and commodity prices, in the course of our normal business operations.  We use derivative instruments to manage such risks.

Interest Rate Derivatives

From time to time, we utilize forward-starting interest rate swaps to hedge the variability of the forecasted interest payments on anticipated debt issuances that may result from changes in the benchmark interest rate until the expected debt is issued. When entering into interest rate swap transactions, we become exposed to both credit risk and market risk. We are subject to credit risk when the change in fair value of the swap instrument is positive and the counterparty may fail to perform under the terms of the contract. We are subject to market risk with respect to changes in the underlying benchmark interest rate that impacts the fair value of the swaps. We manage our credit risk by entering into swap transactions only with major financial institutions with investment-grade credit ratings. We manage our market risk by aligning the swap instrument with the existing underlying debt obligation or a specified expected debt issuance, generally associated with the maturity of an existing debt obligation. We designate the swap agreements as cash flow hedges at inception and expect the changes in values to be highly correlated with the changes in value of the anticipated interest payments associated with the forecasted borrowings.

Commodity Derivatives

Our Merchant Services segment primarily uses exchange-traded refined petroleum product futures contracts to manage the risk of market price volatility on its refined petroleum product inventories and its physical derivative contracts, which we designated as fair value hedges, with changes in fair value of both the futures contracts and physical inventory reflected in earnings.  Our Merchant Services segment also uses exchange-traded refined petroleum contracts to hedge expected future transactions related to certain gasoline inventory, which are designated as cash flow hedges, with the effective portion of the hedge reported in other comprehensive income (“OCI”) and reclassified into earnings when the expected future transaction affects earnings. Any gains or losses incurred on the derivative instruments that are not effective in offsetting changes in fair value or cash flows of the hedged item are recognized immediately in earnings.

Additionally, our Merchant Services segment enters into exchange-traded refined petroleum product futures contracts on behalf of our Domestic Pipelines & Terminals segment to manage the risk of market price volatility on the gasoline-to-butane pricing spreads associated with our butane blending activities. These futures contracts are not designated in a hedge relationship for accounting purposes. Physical forward contracts and futures contracts that have not been designated in a hedge relationship are marked-to-market through earnings.

The following table summarizes the notional volumes of the net long (short) positions of our commodity derivative instruments outstanding at June 30, 2019 (amounts in thousands of gallons):

	Volume
Derivative Purpose	Current		Long-Term
Derivatives NOT designated as hedging instruments:
Physical fixed-price derivative contracts	(29,577	)	(1,201	)
Physical index derivative contracts	(2,476	)	—
Futures contracts for refined petroleum products	25,114		1,638
					Hedge Type
Derivatives designated as hedging instruments:
Cash flow hedge futures contracts	(294	)	—		Cash Flow Hedge
Futures contracts for refined petroleum products	(52,920	)	—		Fair Value Hedge

Our futures contracts designated as fair value hedges relate to our inventory portfolio and extend to the first quarter of 2020. Our futures contracts related to forecasted purchases and sales of refined petroleum products, not designated in a hedging relationship, extend to the first quarter of 2020.

19

In accordance with the Chicago Mercantile Exchange rulebook, variation margin transfers are considered settlement payments, thereby reducing the corresponding derivative asset and liability balances for our exchange-settled derivative contracts. These settlement payments result in realized gains and losses on derivatives.

The following table sets forth the fair value of each classification of derivative instruments and the derivative instruments’ location on our unaudited condensed consolidated balance sheets at the dates indicated (in thousands):

	June 30, 2019

(2) Amounts represent the netting of physical fixed price and index contracts’ assets and liabilities when a legal right of offset exists. 

At June 30, 2019, open refined petroleum product derivative contracts (represented by the physical fixed-price contracts and physical index contracts noted above) were not classified as designated derivative instruments and varied in duration in the overall portfolio, but did not extend beyond January 2020. In addition, at June 30, 2019, we had refined petroleum product inventories that we intend to use to satisfy a portion of the physical derivative contracts.

The change in value recognized in OCI and the losses reclassified from accumulated other comprehensive income (“AOCI”) to income, attributable to our derivative instruments designated as cash flow hedges, were as follows for the periods indicated (in thousands):

	Gain (Loss) Recognized in OCI on Derivatives for the

Total		$	(2,296	)	$	(2,295	)	$	(4,592	)	$	(4,632	)

21

Over the next twelve months, we expect to reclassify $9.2 million of net losses attributable to interest rate derivatives from AOCI to earnings as an increase to interest and debt expense. These net losses consist of $11.2 million of amortization of hedge losses on settled forward-starting interest rate swaps, partially offset by $2.0 million of amortization of hedge gains on settled forward-starting interest rate swaps. Additionally, the unrealized gains and losses for refined petroleum products designated as cash flow hedges at June 30, 2019, of $0.7 million, are estimated to be realized and reclassified from AOCI to product sales over the next twelve months. The ineffective portion of the change in fair value of cash flow hedges was not material for the three and six months ended June 30, 2019 and 2018.

13. FAIR VALUE MEASUREMENTS

We categorize our financial assets and liabilities using the three-tier fair value hierarchy as follows:

Recurring

The following table sets forth financial assets and liabilities measured at fair value on a recurring basis, as of the measurement dates indicated, and the basis for that measurement, by level within the fair value hierarchy (in thousands):

	June 30, 2019					December 31, 2018
	Level 1		Level 2			Level 1		Level 2
Financial assets:
Physical fixed-price derivative contracts	$	—	$	3,330		$	—	$	18,937
Physical index derivative contracts	—		140			—		286
Financial liabilities:
Physical fixed-price derivative contracts	—		(1,380		)	—		(1,389		)
Physical index derivative contracts	—		(40		)	—		(135		)
Fair value	$	—	$	2,050		$	—	$	17,699

The values of the Level 1 derivative assets and liabilities were based on quoted market prices obtained from the New York Mercantile Exchange. The values for exchange-settled commodity derivatives are settled daily via variation margin payments and as a result are with no net fair value at the balance sheet date for financial reporting purposes; however, the derivatives remain outstanding and subject to future commodity price fluctuations until they are settled in accordance with their contractual terms.

The values of the Level 2 commodity derivative contracts were calculated using market approaches based on observable market data inputs, including published commodity pricing data, which is verified against other available market data, and market interest rate and volatility data.  Level 2 physical fixed-price derivative assets are net of credit value adjustments (“CVAs”) determined using an expected cash flow model, which incorporates assumptions about the credit risk of the derivative contracts based on the historical and expected payment history of each customer, the amount of product contracted for under the agreement and the customer’s historical and expected purchase performance under each contract. The CVAs were nominal as of June 30, 2019 and December 31, 2018. As of June 30, 2019 and December 31, 2018, the Merchant Services segment did not hold any net liability derivative positions containing credit contingent features.

Financial instruments included in current assets and current liabilities are reported in the unaudited condensed consolidated balance sheets at amounts which approximate fair value due to the relatively short period to maturity of these financial instruments.  The fair values of our fixed-rate debt were estimated by observing market trading prices and by comparing the historic market prices of our publicly issued debt with the market prices of the publicly issued debt of other MLPs with similar credit ratings and terms.  The fair value of our variable-rate debt approximates the carrying amount since the associated interest rates are market-based. The carrying value and fair value of our debt, using Level 2 input values, were as follows at the dates indicated (in thousands):

	June 30, 2019				December 31, 2018
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Fixed-rate debt	$	3,273,334	$	3,046,533	$	3,546,396	$	3,364,549
Variable-rate debt	566,647		570,275		1,168,046		1,172,328
Total debt	$	3,839,981	$	3,616,808	$	4,714,442	$	4,536,877

22

In addition, our pension plan assets are measured at fair value on a recurring basis, based on Level 1 and Level 3 inputs.

We recognize transfers between levels within the fair value hierarchy as of the beginning of the reporting period.  We did not have any transfers between Level 1 and Level 2 during the six months ended June 30, 2019 and 2018.

Non-Recurring

Certain nonfinancial assets and liabilities are measured at fair value on a nonrecurring basis and are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment. For the three and six months ended June 30, 2019 and 2018, there was no significant fair value adjustments related to such assets or liabilities reflected in our unaudited condensed consolidated financial statements.

14. UNIT-BASED COMPENSATION PLANS

We award unit-based compensation to employees and directors primarily under the 2013 Long Term Incentive Plan of Buckeye Partners, L.P. (the “LTIP”), which was approved by our unitholders in June 2013 and subsequently amended and restated in June 2017. The LTIP replaced the 2009 Long-Term Incentive Plan (the “2009 Plan”), which was merged with and into the LTIP, and no further grants have since been made under the 2009 Plan.

We recognized compensation expense related to awards under the LTIP of $5.8 million and $8.0 million for the three months ended June 30, 2019 and 2018, respectively. For the six months ended June 30, 2019 and 2018, we recognized compensation expense of $15.7 million and $16.8 million, respectively.

LTIP

As of June 30, 2019, there were 1,536,149 LP Units available for issuance under the LTIP.

Deferral Plan under the LTIP

We also maintain the Buckeye Partners, L.P. Unit Deferral and Incentive Plan, as amended and restated effective December 13, 2016 (the “Deferral Plan”), pursuant to which we issue phantom and matching units under the LTIP to certain employees in lieu of cash compensation at the election of the employee. During the six months ended June 30, 2019, 158,970 phantom units (including matching units) were granted under this plan. These grants are included as granted in the LTIP activity table below.

Awards under the LTIP

During the six months ended June 30, 2019, the Compensation Committee of the Board granted 528,750 phantom units to employees (including the 158,970 phantom units granted pursuant to the Deferral Plan, as discussed above), 32,247 phantom units to independent directors of Buckeye GP and 345,574 performance units to employees.

23

The following table sets forth the LTIP activity for the periods indicated (in thousands, except per unit amounts):

	Number of LP Units		Weighted Average Grant Date Fair Value per LP Unit (1)
Unvested at January 1, 2019	1,645		$	55.52
Granted (2)	907		30.97
Vested	(241	)	52.23
Forfeited	(253	)	50.46
Unvested at June 30, 2019	2,058		$	45.71

(1) Determined by dividing the aggregate grant date fair value of awards by the number of awards issued. The weighted-average grant date fair value per LP Unit for forfeited and vested awards is determined before an allowance for forfeitures.

(2) Includes both phantom and performance awards. Performance awards are granted at a target amount but, depending on our performance during the vesting period with respect to certain pre-established goals, the number of LP Units issued upon vesting of such performance awards can be greater or less than the target amount.

At June 30, 2019, we expect to recognize $38.1 million of compensation expense related to the unvested LTIP over a weighted average remaining period of 1.8 years.

15. PARTNERS’ CAPITAL AND DISTRIBUTIONS

Our LP Units represent limited partner interests, which give the holders thereof the right to participate in distributions and to exercise the other rights and privileges available to them under our partnership agreement. The partnership agreement provides that, without prior approval of our limited partners holding an aggregate of at least two-thirds of the outstanding LP Units, we cannot issue any limited partnership interests of a class or series having preferences or other special or senior rights over the LP Units.

Equity Offering

In March 2018, we issued approximately 6.2 million Class C Units in a private placement for aggregate gross proceeds of $265.0 million. The net proceeds were $262.0 million, after deducting issuance costs of approximately $3.0 million. We used the net proceeds from this offering to reduce the indebtedness outstanding under our Credit Facility, to partially fund growth capital expenditures and for general partnership purposes.

Class C Units represented a separate class of our limited partnership interests. The Class C Units were substantially similar in all respects to our existing LP units, except that Buckeye had the option to pay distributions on the Class C Units in cash or by issuing additional Class C Units. In November 2018, all 6,714,963 Class C Units converted into LP Units on a one-for-one basis.

Summary of Changes in Outstanding Units

The following is a summary of changes in Buckeye’s outstanding units for the period indicated (in thousands):

	LP Units
Units outstanding at January 1, 2019	153,755
LP units issued pursuant to the LTIP (1)	166
Units outstanding at June 30, 2019	153,921

(1) The number of LP Units issued represents issuance net of tax withholding.

24

Distributions

Cash distributions are paid for LP Units and for distribution equivalent rights with respect to certain unit-based compensation awards outstanding as of each respective period. Actual cash distributions on our LP Units totaled $232.5 million ($1.50 per LP Unit) and $373.5 million ($2.5250 per LP Unit) during the six months ended June 30, 2019 and 2018, respectively.

On August 1, 2019, we announced a quarterly distribution of $0.75 per LP Unit that will be paid on August 19, 2019 to unitholders of record on August 12, 2019.  Based on the LP Units and distribution equivalent rights with respect to certain unit-based compensation awards outstanding as of June 30, 2019, cash expected to be distributed to LP unitholders on August 19, 2019 is estimated to be approximately $116.3 million.

16. EARNINGS PER UNIT

The following tables set forth the calculation of basic and diluted earnings per unit, attributable to Buckeye’s unitholders, taking into consideration net income allocable to participating securities, as well as the reconciliation of basic weighted average units outstanding to diluted weighted average units outstanding (in thousands, except per unit amounts).

	Three Months Ended June 30,				Six Months Ended June 30,
	2019		2018		2019		2018
Net income attributable to unitholders	$	89,152	$	90,665	$	169,044	$	201,789

Earnings per unit - diluted	$	0.58	$	0.59	$	1.09	$	1.33

17. BUSINESS SEGMENTS

We operate and report in three business segments: (i) Domestic Pipelines & Terminals; (ii) Global Marine Terminals; and (iii) Merchant Services.  All inter-segment transactions have been eliminated in consolidation. 

 Domestic Pipelines & Terminals

The Domestic Pipelines & Terminals segment receives liquid petroleum products from refineries, connecting pipelines, vessels, trains, and bulk and marine terminals, transports those products to other locations for a fee, and provides bulk liquid storage and terminal throughput services.  The segment also has butane blending capabilities and provides crude oil services, including train loading/unloading, storage and throughput. This segment owns and operates pipeline systems and liquid petroleum products terminals in the continental United States, including three terminals owned by the Merchant Services segment but operated by the Domestic Pipelines & Terminals segment, and two underground propane storage caverns.  Additionally, this segment provides turn-key operations and maintenance of third-party pipelines and performs pipeline construction management services typically for cost plus a fixed or variable fee.

25

Global Marine Terminals

The Global Marine Terminals segment provides marine accessible bulk storage and blending services, rail and truck rack loading/unloading along with petroleum processing services across our network of marine terminals located primarily in the East Coast and Gulf Coast regions of the United States, as well as in the Caribbean.  Our operating locations facilitate global flows of crude and refined petroleum products, offer connectivity between supply areas and market centers, and provide premier storage, marine terminalling, blending, and processing services to a diverse customer base.

Adjusted EBITDA

Adjusted EBITDA is a measure not defined by GAAP. We define Adjusted EBITDA as earnings (losses) before interest expense, income taxes, depreciation and amortization, further adjusted to exclude certain non-cash items, such as non-cash compensation expense; transaction, transition, and integration costs associated with acquisitions and dispositions; certain gains and losses on foreign currency transactions and foreign currency derivative financial instruments, as applicable; and certain other operating expense or income items, reflected in net income, that we do not believe are indicative of our core operating performance results and business outlook, such as hurricane-related costs, gains and losses on property damage recoveries, non-cash impairment charges, and gains and losses on asset sales. The definition of Adjusted EBITDA is also applied to our proportionate share in the Adjusted EBITDA of significant equity method investments, which from January 1, 2017 through September 30, 2018, included VTTI, and is not applied to our less significant equity method investments. The calculation of our proportionate share of the reconciling items used to derive Adjusted EBITDA was based upon our 50% equity interest in VTTI, prior to adjustments related to noncontrolling interests in several of its subsidiaries and partnerships, which were immaterial. Adjusted EBITDA is a non-GAAP financial measure that is used by our senior management, including our Chief Executive Officer, to assess the operating performance of our business and optimize resource allocation. We use Adjusted EBITDA as a primary measure to: (i) evaluate our consolidated operating performance and the operating performance of our business segments; (ii) allocate resources and capital to business segments; (iii) evaluate the viability of proposed projects; and (iv) determine overall rates of return on alternative investment opportunities. 

We believe that investors benefit from having access to the same financial measures that we use and that these measures are useful to investors because they aid in comparing our operating performance with that of other companies with similar operations.  The Adjusted EBITDA data presented by us may not be comparable to similarly titled measures at other companies because these items may be defined differently by other companies.

(1) Includes 100% of the depreciation and amortization expense of $18.2 million and $36.0 million for Buckeye Texas for the three and six months ended June 30, 2018, respectively.

(2) Represents transaction, internal and third-party costs related to the Merger, asset acquisitions, dispositions, and integration.

(3) Due to the significance of our equity method investment in VTTI, effective January 1, 2017 through September 30, 2018, we applied the definition of Adjusted EBITDA, covered in our description of Adjusted EBITDA, with respect to our proportionate share of VTTI’s Adjusted EBITDA. The calculation of our proportionate share of the reconciling items used to derive Adjusted EBITDA was based upon our 50% equity interest in VTTI, prior to adjustments related to noncontrolling interests in several of its subsidiaries and partnerships, which were immaterial.

(4) Represents the loss on early extinguishment of the $275.0 million principal amount outstanding under our 5.500% notes and $250.0 million variable-rate Term Loan.

(5) Represents gains on recoveries of property damages caused by third parties, which primarily related to a settlement in connection with a 2012 vessel allision with a jetty at our BBH facility in the Bahamas.

(6) Represents costs incurred at our BBH facility in the Bahamas, Yabucoa Terminal in Puerto Rico, Corpus Christi facilities in Texas, and certain terminals in Florida, as a result of hurricanes, which occurred in 2017 and 2016, including operating expenses and write-offs of damaged long-lived assets, net of insurance recoveries.

Overview of Business

Business

We are a growth-oriented master limited partnership principally engaged in owning and operating a diversified network of integrated assets providing midstream logistic solutions, primarily consisting of the transportation, storage, processing and marketing of liquid petroleum products. Our assets include terminals and processing facilities that we own and underground liquid petroleum product pipelines installed along rights-of-way acquired from land owners and related above-ground facilities. The majority of our service-based revenue is derived from fee-based transportation, terminalling, and storage services that we provide to our customers. We also generate revenue from the marketing and sale of petroleum products. Our business activities are conducted through three reportable segments:

• Our Domestic Pipelines & Terminals segment, comprised of approximately 6,000 miles of pipeline with 110 terminal locations;

• Our Global Marine Terminals segment, consisting of seven liquid petroleum product terminals located in key global energy hubs with 62 million barrels of liquid petroleum product storage capacity; and

• Our Merchant Services segment, which markets refined petroleum products primarily in conjunction with the facilities owned by our other segments. 

31

Merger Agreement

On May 10, 2019, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Hercules Intermediate Holdings LLC, a Delaware limited liability company and an affiliate of IFM Global Infrastructure Fund (“Parent”), Hercules Merger Sub LLC, a Delaware limited liability company and a wholly owned subsidiary of Parent (“Merger Sub”), Buckeye Pipe Line Services Company, a Pennsylvania corporation (“ServiceCo”), and Buckeye GP. The Merger Agreement, which has been unanimously approved by the board of directors of Buckeye GP (“the Board”) on our behalf, provides for the merger of Merger Sub with and into Buckeye (the “Merger”), with Buckeye surviving the Merger as a wholly owned subsidiary of Parent. After the Merger, Buckeye’s LP Units will cease to be publicly traded.

Subject to the terms and conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each of our issued and outstanding LP Units (other than LP Units owned immediately prior to the Effective Time by us, by Parent or any of its affiliates or under certain circumstances by ServiceCo), will be converted into the right to receive $41.50 in cash per LP Unit (the “Merger Consideration”), without interest.

Completion of the Merger is subject to customary closing conditions, including unitholder and certain regulatory approvals. On July 31, 2019, the Merger Agreement and the transactions contemplated thereby were approved by the affirmative vote of the holders of a majority of the outstanding LP Units entitled to vote thereon. We expect the Merger to close during the fourth quarter of 2019.

For more information regarding the Merger and the Merger Agreement, please see our Form 8-K filed with the SEC on May 10, 2019 and our Schedule 14A filed with the SEC on June 25, 2019, as supplemented by the Form 8-K we filed with the SEC on July 22, 2019.

Strategy

Our primary business objective is to create value by generating stable cash flows that may be distributed to our unitholders or reinvested in the business, while maintaining a relatively low investment risk profile.  The key elements of our strategy are to:

• Operate in a safe, regulatory compliant, and environmentally responsible manner;

• Maximize utilization and efficiency of our assets;

• Maintain strong, stable and long-term customer relationships;

• Optimize, expand and diversify our portfolio of energy assets through strategic investments;

• Maintain a strong financial position including our investment-grade credit rating; and

• Retain a portion of our internally generated cash flow and utilize capacity under our $1.5 billion revolving Credit Facility with SunTrust Bank (the “Credit Facility”) to fund our planned growth initiatives without the need to access the public equity markets for the foreseeable future.

We intend to achieve our strategy by:

• Building, acquiring and operating high quality, strategically-located assets and continually evaluating potential monetization opportunities related to our current asset portfolio;

• Maintaining and enhancing the integrity of our pipelines, terminals and storage assets, and operating them in a safe and environmentally responsible manner;

• Seeking to acquire or develop other energy-related assets without compromising our strong financial position that:

• Complement our existing footprint;

• Provide geographic, product and/or asset class diversity; and

• Leverage existing management capabilities and infrastructure;

• Valuing the effort, teamwork and innovation of our employees; and

• Providing superior customer service.

Recent Developments

VTTI Divestiture

In November 2018, we executed a definitive agreement to sell our 50% equity interest in VTTI for approximately $975.0 million, excluding transaction costs of approximately $4.0 million incurred in 2019, plus a final earnings distribution of $22.6 million received in the fourth quarter of 2018. The sale closed in January 2019.

DPTS Asset Package Divestiture

On December 17, 2018, we sold certain domestic pipeline and terminal assets, which included (i) our jet fuel pipeline from Port Everglades, Florida to Ft. Lauderdale-Hollywood International Airport and Miami International Airport; (ii) our pipelines and terminal facilities serving Reno-Tahoe International Airport, San Diego International Airport, and the Federal Express Corporation terminal at the Memphis International Airport; and (iii) our refined petroleum product terminals in Sacramento, California and Stockton, California (collectively, the “DPTS asset package”). The final payment of $10.0 million was received in June 2019.

South Texas Transactions

South Texas Gateway Terminal LLC (“STG Terminal”) is expected to commence and ramp up operations by mid-2020, and is supported by long-term minimum volume throughput commitments and storage contracts from credit-worthy customers, including our joint-venture partners. We own a 50% interest in STG Terminal, and Phillips 66 Partners LP and Gray Oak Gateway Holdings, a subsidiary of Marathon Petroleum Corporation, each own a 25% interest. The total construction cost for STG Terminal is estimated on a 100% basis at $574.0 million, or a net of $287.0 million to our interest. To date, our net investment is $72.5 million, including $31.8 million of net contributions during the six months ended June 30, 2019. We account for our interest in STG Terminal, which is included in our Global Marine Terminals segment, using the equity method of accounting.

Notes Repayments

In January 2019, we repaid in full the $250.0 million variable-rate Term Loan due September 30, 2019 (the “Term Loan”), using proceeds from the VTTI sale transaction.

In February 2019, we repaid in full the $275.0 million principal amount outstanding under our 5.500% notes, using proceeds from the VTTI sale transaction as well as borrowings under our Credit Facility.

As a result of the retirements, we incurred a $4.0 million loss on early extinguishment of debt, consisting of a $3.6 million make-whole payment related to the 5.500% notes and unamortized financing costs of $0.4 million included in Other expense, net, on our unaudited condensed consolidated statements of operations.

Non-GAAP Financial Measures

Adjusted EBITDA and distributable cash flow are not measures defined by accounting principles generally accepted in the United States of America (“GAAP”). We define Adjusted EBITDA as earnings (losses) before interest expense, income taxes, depreciation and amortization, further adjusted to exclude certain non-cash items, such as non-cash compensation expense; transaction, transition, and integration costs associated with acquisitions and dispositions; certain unrealized gains and losses on foreign currency transactions and foreign currency derivative financial instruments, as applicable; and certain other operating expense or income items, reflected in net income, that we do not believe are indicative of our core operating performance results and business outlook, such as hurricane-related costs, gains and losses on property damage recoveries, non-cash impairment charges, and gains and losses on asset sales. We define distributable cash flow as Adjusted EBITDA less cash interest expense, cash income tax expense, and maintenance capital expenditures incurred to maintain the operating, safety, and/or earnings capacity of our existing assets, plus or minus realized gains or losses on certain foreign currency derivative financial instruments, as applicable. These definitions of Adjusted EBITDA and distributable cash flow are also applied to our proportionate share in the Adjusted EBITDA of significant equity method investments, which from January 1, 2017 through September 30, 2018, included VTTI, and is not applied to our less significant equity method investments. The calculation of our proportionate share of the reconciling items used to derive Adjusted EBITDA was based upon our 50% equity interest in VTTI, prior to adjustments related to noncontrolling interests in several of its subsidiaries and partnerships, which were immaterial. Adjusted EBITDA and distributable cash flow are non-GAAP financial measures that are used by our senior management, including our Chief Executive Officer, to assess the operating performance of our business and optimize resource allocation. We use Adjusted EBITDA as a primary measure to: (i) evaluate our consolidated operating performance and the operating performance of our business segments; (ii) allocate resources and capital to business segments; (iii) evaluate the viability of proposed projects; and (iv) determine overall rates of return on alternative investment opportunities.  We use distributable cash flow as a performance metric to compare cash-generating performance of Buckeye from period to period and to compare the cash-generating performance for specific periods to the cash distributions (if any) that are expected to be paid to our unitholders. Distributable cash flow is not intended to be a liquidity measure.

We believe that investors benefit from having access to the same financial measures used by management and that these measures are useful to investors because they aid in comparing our operating performance with that of other companies with similar operations.  The Adjusted EBITDA and distributable cash flow data presented by us may not be comparable to similarly titled measures at other companies because these items may be defined differently by other companies.

Three Months Ended June 30, 2019 Compared to Three Months Ended June 30, 2018

Consolidated Overview

Net income was $90.5 million for the three months ended June 30, 2019, a decrease of $2.8 million, or 3.0%, from net income of $93.3 million for the corresponding period in 2018.  The decrease was driven by (i) lower operating results from the Global Marine Terminals segment’s segregated storage services, partially offset by increased contribution from our South Texas operations; (ii) a $5.4 million decrease in earnings from equity investments resulting from the sale of our interest in VTTI; and (iii) a $5.6 million increase in transaction costs associated with the Merger announced in May 2019. The unfavorable impact of these factors was partially offset by (i) lower interest and debt expense of $10.0 million due to the retirement of debt in the previous quarter, (ii) an increase of $2.5 million in hurricane-related insurance recoveries, net of costs, and (iii) improved operating results in the Merchant Services segment, as further explained in the discussion of Adjusted EBITDA by segment below.

Total Adjusted EBITDA was $214.3 million for the three months ended June 30, 2019, a decrease of $40.6 million, or 15.9%, from $254.9 million for the corresponding period in 2018.  The decrease in Adjusted EBITDA was driven by decreases in Adjusted EBITDA of $44.5 million and $2.4 million from our Global Marine Terminals and Domestic Pipelines & Terminals segments, respectively, which were partially offset by a $6.3 million increase in our Merchant Services segment, as further explained in the discussion of Adjusted EBITDA by segment below.

Distributable cash flow was $140.0 million for the three months ended June 30, 2019, a decrease of $22.0 million, or 13.6%, from $162.0 million for the corresponding period in 2018, primarily driven by a $40.6 million decrease in Adjusted EBITDA from our segments, as further described below. This net decrease in distributable cash flow resulting from the decrease in Adjusted EBITDA was partially offset by a $9.6 million decrease in our interest and debt expense, excluding amortization of deferred financing costs, debt discounts, and debt retirement costs, and a $0.7 million increase in maintenance capital expenditures, excluding hurricane-related maintenance capital expenditures. The contribution to distributable cash flow from VTTI for the three months ended June 30, 2018 was $25.5 million, excluding the debt financing costs associated with this investment.

Adjusted EBITDA by Segment

Domestic Pipelines & Terminals. Adjusted EBITDA from the Domestic Pipelines & Terminals segment was $133.0 million for the three months ended June 30, 2019, a decrease of $2.4 million, or 1.8%, from $135.4 million for the corresponding period in 2018. Contributing to the decrease in Adjusted EBITDA was a $7.7 million decrease in operating income related to the sale of the DPTS asset package in December 2018.

Pipeline volumes increased by 0.4% due to strong demand for distillate shipments. Terminalling volumes increased by 2.3%, primarily due to higher distillate and gasoline volumes, reflecting strong customer throughput demand, particularly in our Midwest region. These volume increases are after adjusting for the prior period volumes associated with the divested DPTS asset package.

After adjusting for the impact of the DPTS asset package sale, pipeline rate increases resulted in a transportation revenue increase of $2.7 million. These increases reflect contributions from internal growth capital investments as well as increases in certain tariff rates, but exclude product recoveries and other pipeline revenues. In addition, butane blending and other revenues increased by $4.5 million, while terminal throughput revenues increased by $1.6 million due to higher volumes. These revenue increases were offset by (i) a $2.4 million decrease in storage revenue, primarily due to lower storage rates and utilization and (ii) a decrease of $2.9 million in product recoveries resulting from lower terminal settlement prices. A $3.1 million decrease in operating expenses was primarily driven by lower general and administrative expenses as a result of lower professional fees, partially offset by higher maintenance costs.

Global Marine Terminals.  Adjusted EBITDA from the Global Marine Terminals segment was $76.2 million for the three months ended June 30, 2019, a decrease of $44.5 million, or 36.9%, from $120.7 million for the corresponding period in 2018.  The decrease in Adjusted EBITDA was primarily due to an $8.9 million decrease in revenue and a $34.6 million decrease in the Adjusted EBITDA contribution from our former equity investment in VTTI due to the divestiture of our equity interest in January 2019, which were partially offset by a $0.9 million increase in Adjusted EBITDA resulting from the acquisition of our business partner’s 20% equity interest in Buckeye Texas in April 2018.

37

The decrease in revenue was due to an $11.0 million decrease in revenue from storage and terminalling services, reflecting lower capacity utilization and average rates, primarily due to lower demand for segregated storage services at our Caribbean and, to a lesser extent, our New York Harbor facilities as a result of overall weaker market conditions for storage. These factors were partially offset by a $3.2 million increase in revenue related to our South Texas operations principally due to contractual rate escalations. The average capacity utilization (i.e., ratio of contracted capacity to capacity available to be contracted) of our marine storage assets was 79% for the three months ended June 30, 2019, which was an increase from 77% in the sequential prior quarter and a decrease from 85% in the corresponding period in 2018.

Merchant Services.  Adjusted EBITDA from the Merchant Services segment was $5.1 million for the three months ended June 30, 2019, an increase of $6.3 million from $(1.2) million for the corresponding period in 2018.  Adjusted EBITDA was positively impacted by an increased contribution from both gas and distillate portfolio management due to increased pricing spreads as compared to the prior year period, and a decrease in operating expenses of $2.7 million, driven by a recovery of a bad debt expensed in the second quarter of 2018. This increase was partially offset by lower rack sales margins.

Revenue from bulk and rack product sales decreased by $135.9 million due to (i) a $112.2 million decrease resulting from lower volumes, due to inventory management and margin optimization efforts and (ii) a $23.7 million decrease in refined petroleum product sales due to lower average sales prices per gallon of $2.02 for 2019 as compared to $2.13 for the prior year period.

Cost of product sales, including both bulk and rack sales, decreased by a corresponding $139.5 million primarily due to (i) a $111.4 million decrease due to the sales volume declines and (ii) a $28.1 million decrease in refined petroleum product cost due to lower average cost per gallon of $1.99 for 2019 as compared to $2.12 for the prior year period.

Six Months Ended June 30, 2019 Compared to Six Months Ended June 30, 2018

Consolidated Overview

Net income was $171.8 million for the six months ended June 30, 2019, a decrease of $38.6 million, or 18.4%, from $210.4 million for the corresponding period in 2018. The decrease was driven by (i) lower operating results from the Global Marine Terminals segment’s segregated storage services, partially offset by an increased contribution from our South Texas operations; (ii) a decrease in insurance recoveries of $14.5 million related to a property damage claim in the prior year period; (ii) a $4.0 million loss on early extinguishment of debt included in Other expense, net; (iii) a $9.5 million decrease in earnings from equity investments; and (iv) a $9.5 million increase in transaction costs related to the sale of our equity method investment in VTTI in January 2019 and the Merger announced in May 2019. The unfavorable impact of these factors was partially offset by an increase of $4.0 million in hurricane-related insurance recoveries, net of costs, and lower interest and debt expense of $17.0 million due to the retirement of debt in the current period as well as improved operating results in the Merchant Services segment, as further explained in the discussion of Adjusted EBITDA by segment below.

Adjusted EBITDA was $430.7 million for the six months ended June 30, 2019, which was a decrease of $85.9 million, or 16.6%, from $516.6 million for the corresponding period in 2018.  The decrease in Adjusted EBITDA was driven by decreases in Adjusted EBITDA of $86.4 million and $7.1 million from our Global Marine Terminals and Domestic Pipelines & Terminals segments, respectively, which were partially offset by a $7.6 million increase in our Merchant Services segment, as further explained in the discussion of Adjusted EBITDA by segment below.

Distributable cash flow was $284.5 million for the six months ended June 30, 2019, which was a decrease of $46.7 million, or 14.1%, from $331.2 million as compared to the corresponding period in 2018.  The decrease in distributable cash flow was primarily related to a decrease of $85.9 million in Adjusted EBITDA as described above. This decrease was partially offset by a $16.3 million decrease in interest and debt expense, excluding amortization of deferred financing costs, debt discounts and other, and a $2.4 million decrease in maintenance capital expenditures, excluding hurricane-related maintenance capital expenditures, reflecting the completion of certain projects during the prior year. The contribution to distributable cash flow from VTTI for the six months ended June 30, 2018 was $49.2 million, excluding the debt financing costs associated with this investment.

38

Adjusted EBITDA by Segment

Domestic Pipelines & Terminals. Adjusted EBITDA from the Domestic Pipelines & Terminals segment was $268.9 million for the six months ended June 30, 2019, which was a decrease of $7.1 million, or 2.6%, from $276.0 million for the corresponding period in 2018.  Contributing to the decrease in Adjusted EBITDA was a $16.0 million decrease in operating income, related to the sale of the DPTS asset package in December 2018.

After adjusting for the impact of the DPTS asset package sale, pipeline rate increases resulted in transportation revenue increases of $9.9 million. These increases reflect contributions from internal growth capital investments as well as increases in certain tariff rates but exclude product recoveries and other pipeline revenues. In addition, rental and other revenues increased by $4.2 million, while terminal throughput revenues increased by $1.1 million due to higher volumes. These revenue increases were offset by (i) a $6.5 million decrease in storage revenue, primarily due to lower storage rates and capacity utilization and (ii) a decrease of $4.0 million in product recoveries resulting from lower terminal settlement prices. A $5.5 million decrease in operating expenses was primarily driven by lower general and administrative expenses as a result of lower professional fees, partially offset by increased maintenance costs.

Pipeline volumes increased by 0.8% due to strong demand for distillate shipments. Terminalling volumes increased by 2.2%, primarily due to higher distillate and gasoline volumes, reflecting strong customer throughput demand, particularly in our Southeast region. These volume increases are after adjusting for the prior period volumes associated with the divested DPTS asset package.

Global Marine Terminals.  Adjusted EBITDA from the Global Marine Terminals segment was $151.7 million for the six months ended June 30, 2019, which was a decrease of $86.4 million, or 36.3%, from $238.1 million for the corresponding period in 2018.  The decrease in Adjusted EBITDA was primarily due to an $18.9 million decrease in revenue and a $69.2 million decrease in the Adjusted EBITDA contribution from our former equity investment in VTTI due to the divestiture of our equity interest in January 2019, which were partially offset by a $5.1 million increase in Adjusted EBITDA resulting from the acquisition of our business partner’s 20% equity interest in Buckeye Texas in April 2018.

The decrease in revenue was due to a $23.7 million decrease in revenue from storage and terminalling services, reflecting lower capacity utilization and average rates, primarily due to lower demand from segregated storage services at our Caribbean and, to a lesser extent, our New York Harbor facilities as a result of overall weaker market conditions. These factors were partially offset by a $5.9 million increase in revenue related to our South Texas operations principally due to contractual rate escalations. The average capacity utilization (i.e., ratio of contracted capacity to capacity available to be contracted) of our marine storage assets was 78% for the six months ended June 30, 2019, which was a decrease from 87% in the corresponding period in 2018.

Merchant Services.  Adjusted EBITDA from the Merchant Services segment was $10.1 million for the six months ended June 30, 2019, which was an increase of $7.6 million from $2.5 million for the corresponding period in 2018. Adjusted EBITDA was positively impacted by an increased contribution from both gas and distillate portfolio management due to increased pricing spreads as compared to the prior year period, and a decrease in operating expenses of $3.2 million, driven by a recovery of a bad debt expensed in the second quarter of 2018. This increase was partially offset by lower rack sales margins.

Revenue from bulk and rack product sales decreased by $264.7 million due to (i) a $79.5 million decrease resulting from lower volumes, due to decreased demand in distillate rack sales and (ii) a $185.2 million decrease in refined petroleum product sales due to lower average sales prices per gallon of $1.93 for 2019 as compared to $2.26 for the prior year period.

Cost of product sales, including both bulk and rack sales, decreased by $269.1 million primarily due to (i) a $78.9 million decrease due to lower sales volumes and (ii) a $190.2 million decrease in refined petroleum product cost due to lower average cost per gallon of $1.91 for 2019 as compared to $2.24 for the prior year period.

Liquidity and Capital Resources

General

Our primary cash requirements, in addition to normal operating expenses and debt service, are for working capital, capital expenditures, equity investments, business acquisitions and distributions to unitholders.  Our principal ongoing sources of liquidity are cash from operations and borrowings under our $1.5 billion revolving Credit Facility.  We will, from time to time, issue debt securities to refinance amounts borrowed under our Credit Facility.  Buckeye Energy Services LLC, Buckeye West Indies Holdings LP, and Buckeye Caribbean Terminals LLC (collectively the Buckeye Merchant Service Companies or “BMSC”) fund their working capital needs principally from their own operations and their portion of our Credit Facility.  Our financial policy is to fund maintenance capital expenditures with cash from continuing operations.  Expansion and cost reduction capital expenditures, along with acquisitions and investments, are currently being funded from internally generated cash flow and borrowings under our Credit Facility. Our goal continues to be to maintain an appropriate distribution coverage ratio, leverage ratio and an investment-grade credit rating. We retain sufficient cash flow to fund a portion of our near-term annual growth capital projects without the need to access the public equity markets. Based on current market conditions, we believe our borrowing capacity under our Credit Facility and cash flows from operations will be sufficient to fund our primary cash requirements including growth capital funding. We continually evaluate engaging in strategic transactions for potential additional sources of capital which may include (i) divesting non-strategic assets where our evaluation suggests such a transaction is in the best interest of our unitholders, including the potential monetization of full or partial equity interests in certain joint ventures or other assets, (ii) issuances of public or private debt and (iii) investments from private sources of capital.  We believe availability under our Credit Facility in combination with our cash flows from operations, as well as the use of other sources of capital described above, where appropriate, will be sufficient to fund our current expansion plans over the next twelve months while maintaining adequate liquidity without the need for additional public equity. In the fourth quarter of 2018 and January 2019, we raised a total of approximately $1.4 billion through asset divestitures which was used to reduce debt.

Current Liquidity

As of June 30, 2019, we had a working capital deficit of $43.1 million, and available borrowing capacity under our Credit Facility is limited to $1,162.0 million as a result of certain quarterly financial covenants.

Capital Structure Transactions

We have a universal shelf registration statement that does not place any dollar limits on the amount of debt and equity securities that we may issue thereunder and a traditional shelf registration statement on file with the SEC that allows us to issue up to an aggregate of $1 billion in equity securities. The universal and traditional shelf registration statements will expire in November and December 2020, respectively.

The timing of any transaction may be impacted by events, such as strategic growth opportunities, legal judgments or regulatory or environmental requirements.  The receptiveness of the capital markets to an offering of debt or equity securities cannot be assured and may be negatively impacted by, among other things, our long-term business prospects and other factors beyond our control, including market conditions.

Capital Allocation

We continually review our investment options with respect to our capital resources that are not distributed to our unitholders or used to pay down our debt and seek to invest these capital resources in various projects and activities based on their return on investment.  Potential investments could include, among others: add-on or other enhancement projects associated with our current assets; greenfield or brownfield development projects; and merger and acquisition activities.

Debt

In January 2019, we repaid in full the $250.0 million Term Loan, using proceeds from the VTTI sale transaction.

In February 2019, we repaid in full the $275.0 million principal amount outstanding under our 5.500% notes, using proceeds from the VTTI sale transaction as well as borrowings under our Credit Facility.

40

As a result of these retirements, we incurred a $4.0 million loss on early extinguishment of debt, consisting of a $3.6 million make-whole payment related to the 5.500% notes and unamortized financing costs of $0.4 million included in Other expense, net, on our unaudited condensed consolidated statements of operations.

At June 30, 2019, we had total fixed-rate and variable-rate debt obligations of $3,273.3 million and $566.6 million, respectively, with an aggregate fair value of $3,616.8 million. At June 30, 2019, we were in compliance with the covenants under our Credit Facility.

Cash Flows from Operating, Investing and Financing Activities

The following table summarizes our cash flows from operating, investing and financing activities for the periods indicated (in thousands):

Net increase (decrease) in cash and cash equivalents	$	4,461		$	(523	)

Operating Activities

Net cash provided by operating activities of $349.6 million for the six months ended June 30, 2019 primarily resulted from $171.8 million of net income, adjusted for (i) $129.7 million of depreciation and amortization expense, (ii) $15.7 million of non-cash unit-based compensation expense, (iii) $14.9 million net decrease in the fair value of derivative assets, and (iv) a $79.8 million decrease to inventory, reflecting reduced inventory levels in the Merchant Services segment, which were partially offset by a $42.8 million decrease in accounts payable, a $16.3 million increase in prepaid and other current assets, and a $4.1 million decrease in accounts receivable.

Net cash provided by operating activities of $431.1 million for the six months ended June 30, 2018 primarily resulted from $210.4 million of net income, adjusted for $130.7 million of depreciation and amortization expense and a $62.0 million decrease in net working capital items, primarily reflecting a decrease in liquid petroleum products inventory in the Merchant Services segment, partially offset by a decrease in related accounts payable.

Future Operating Cash Flows. Our future operating cash flows will vary based on a number of factors, many of which are beyond our control, including demand for our services, the cost of commodities, the effectiveness of our strategy, legal, environmental and regulatory requirements and our ability to capture value associated with commodity price volatility.

Investing Activities

Net cash provided by investing activities of $771.6 million for the six months ended June 30, 2019 primarily related to $985.0 million proceeds from the sale of VTTI and the DPTS asset package, as discussed in Note 3 - Acquisitions, Investments, and Disposition of the Notes to Unaudited Condensed Consolidated Financial Statements, partially offset by $191.2 million of capital expenditures and $38.2 million in contributions to our equity investment in connection with the funding of the on-going construction activities at the STG Terminal joint venture.

Net cash used in investing activities of $235.2 million for the six months ended June 30, 2018 primarily resulted from $250.0 million of capital expenditures.

Financing Activities

Net cash used in financing activities of $1,116.7 million for the six months ended June 30, 2019 primarily resulted from $231.8 million of cash distributions paid to our unitholders ($1.5000 per LP Unit), a $525.0 million principal repayment of our 5.500% notes and Term Loan, $352.1 million of net repayments under the Credit Facility, and a $3.6 million make-whole payment related to the early extinguishment of debt.

41

Net cash used in financing activities of $196.5 million for the six months ended June 30, 2018 primarily resulted from $372.2 million of cash distributions paid to our unitholders ($2.5250 per LP Unit), a $300.0 million principal repayment of our 6.050% notes, and a $210.0 million acquisition of our business partner’s 20% interest in our Buckeye Texas consolidated subsidiary, partially offset by $394.9 million of net proceeds from our 6.375% notes issuance, $262.0 million of net proceeds from the issuance of 6.2 million Class C Units in a private placement, and $40.6 million of net borrowings under the Credit Facility.

Capital Expenditures

We have capital expenditures, which we define as “maintenance capital expenditures,” in order to maintain and enhance the safety and integrity of our pipelines, terminals, storage and processing facilities and related assets, and “expansion and cost reduction capital expenditures” to expand the reach or capacity of those assets, to improve the efficiency of our operations and to pursue new business opportunities.  Capital expenditures were as follows for the periods indicated (in thousands):

	Six Months Ended June 30,
	2019		2018
Maintenance capital expenditures (1)	$	51,431	$	56,766
Expansion and cost reduction	139,735		193,269
Total capital expenditures (2)	$	191,166	$	250,035

____________________________

(1) Includes maintenance capital expenditures of $0.3 million and $3.3 million related to the BBH facility and Yabucoa Terminal in Puerto Rico as a result of Hurricanes Matthew and Maria for the six months ended June 30, 2019 and 2018, respectively.

(2) Amounts exclude the impact of changes in accruals for capital expenditures. On an accrual basis, capital expenditure additions to property, plant and equipment were $163.6 million and $252.2 million for the six months ended June 30, 2019 and 2018, respectively.

Total capital expenditures decreased for the six months ended June 30, 2019, as compared to the corresponding period in 2018, primarily due to completion of certain expansion and cost reduction capital projects. Our expansion and cost reduction capital expenditures were $139.7 million for the six months ended June 30, 2019, a decrease of $53.6 million, or 27.7%, from $193.3 million for the corresponding period in 2018. The period-over-period fluctuations in our expansion and cost reduction capital expenditures primarily reflect the completion of significant portions of certain large organic-growth capital projects, including the Michigan/Ohio Pipeline Expansion Project, Jacksonville Terminals, St. Lucia Tank Upgrades, and Chicago Complex. Our maintenance capital expenditures were $51.4 million for the six months ended June 30, 2019, a decrease of $5.4 million, or 9.5%, from $56.8 million for the corresponding period in 2018, primarily driven by a temporary increase in maintenance capital during the first half of 2018 related to upgrades in station and terminal equipment, asset integrity work necessary to maintain operating capacity, and repairs to our Yabucoa facility as a result of Hurricane Maria.

42

We have estimated our capital expenditures as follows for the year ending December 31, 2019 (in thousands):

	2019
	Low		High
Domestic Pipelines & Terminals:
Maintenance capital expenditures	$	75,000	$	85,000
Expansion and cost reduction	140,000		155,000
Total capital expenditures	$	215,000	$	240,000
Global Marine Terminals:
Maintenance capital expenditures	$	35,000	$	40,000
Expansion and cost reduction (1)	35,000		45,000
Total capital expenditures	$	70,000	$	85,000
Overall:
Maintenance capital expenditures	$	110,000	$	125,000
Expansion and cost reduction	175,000		200,000
Total capital expenditures	$	285,000	$	325,000

_________________________

(1)   Excludes our estimated capital contributions to unconsolidated joint ventures for expansion expenditures. In 2019, our capital contributions to STG Terminal joint venture are expected to fall within the range from $135.0 million to $145.0 million, depending on the timing of the construction of STG Terminal.

Estimated maintenance capital expenditures include tank refurbishments and upgrades to station and terminalling equipment, asset integrity, field instrumentation and cathodic protection systems and exclude capital expenditures expected to be incurred in response to hurricane related damages. Estimated major expansion and cost reduction expenditures include the continuing capacity expansion of our pipeline system and terminalling capacity in the Midwest, continued investment in South Texas facilities, and various tank construction and conversion projects in our Global Marine Terminals and Domestic Pipelines & Terminals segments.

Off-Balance Sheet Arrangements

At June 30, 2019 and December 31, 2018, we had no off-balance sheet debt or arrangements.

The following should be read in conjunction with Quantitative and Qualitative Disclosures About Market Risk included under Item 7A in our Annual Report on Form 10-K for the year ended December 31, 2018.  There have been no material changes in that information other than as discussed below.  Also, see Part I, Item 1, Financial Statements, Note 12 - Derivative Instruments and Hedging Activities in the Notes to Unaudited Condensed Consolidated Financial Statements for additional discussion.

Market Risk — Non-Trading Instruments

We are exposed to financial market risks, including changes in commodity prices and interest rates. The primary factors affecting our market risk and the fair value of our derivative portfolio at any point in time are the volume of open derivative positions, changing refined petroleum commodity prices, and prevailing interest rates for our interest rate swaps.  We are also susceptible to basis risk created when we enter into financial hedges that are priced at a certain location, but the sales or exchanges of the underlying commodity are at another location where prices and price changes might differ from the prices and price changes at the location upon which the hedging instrument is based.  Since prices for refined petroleum products and interest rates are volatile, there may be material changes in the fair value of our derivatives over time, driven both by price volatility and the changes in volume of open derivative transactions.

The following is a summary of changes in fair value of our commodity derivative instruments for the periods indicated (in thousands):

	Commodity Instruments
Fair value of contracts outstanding at January 1, 2019	$	17,699
Cash settlements during the period	20,463
Change in fair value attributable to new deals during the period	(579		)
Change in fair value attributable to existing deals at January 1st	(35,533		)
Fair value of contracts outstanding at June 30, 2019	$	2,050

Commodity Price Risk

Our Merchant Services segment primarily uses exchange-traded refined petroleum product futures contracts to manage the risk of market price volatility on its refined petroleum product inventories and its physical contracts accounted for at fair value.  In addition, the segment uses exchange-traded refined petroleum product futures and over-the-counter traded physical fixed-price derivative contracts to hedge expected future transactions related to certain forecasted purchases and sales of refined petroleum products. Finally, our Merchant Services segment enters into exchange-traded refined petroleum product futures contracts on behalf of our Domestic Pipelines & Terminals segment to manage the risk of market price volatility on pricing spreads between gasoline and butane inventory in connection with our butane blending activities managed by a third party. Based on a hypothetical 10% movement in the underlying quoted market prices of the futures contracts, as well as observable market data from third-party pricing publications for refined petroleum product inventories and physical contracts accounted for at fair value designated in hedging relationships at June 30, 2019, the estimated fair value, excluding variation margins, would be as follows (in thousands): 

Scenario	Resulting Classification	Fair Value
Fair value assuming no change in underlying commodity prices (as is)	Asset	$	104,389
Fair value assuming 10% increase in underlying commodity prices	Asset	$	101,627
Fair value assuming 10% decrease in underlying commodity prices	Asset	$	107,151

Interest Rate Risk

From time to time, we utilize forward-starting interest rate swaps to hedge the variability of the forecasted interest payments on anticipated debt issuances that may result from changes in the benchmark interest rate until the expected debt is issued.  When entering into interest rate swap transactions, we are exposed to both credit risk and market risk.  We manage our credit risk by entering into swap transactions only with major financial institutions with investment-grade credit ratings.  We are subject to credit risk when the change in fair value of the swap instruments is positive and the counterparty may fail to perform under the terms of the contract.  We are subject to market risk with respect to changes in the underlying benchmark interest rate that impact the fair value of swaps.  We manage our market risk by aligning the swap instrument with the existing underlying debt obligation or a specified expected debt issuance generally associated with the maturity of an existing debt obligation.

Our practice with respect to derivative transactions related to interest rate risk has been to have each transaction in connection with non-routine borrowings authorized by the Board. Our interest rate hedging policy permits us to enter into certain short-term interest rate swap agreements to manage our interest rate and cash flow risks associated with a credit facility. Currently, we have no outstanding interest rate swaps.

See Part I, Item 1, Financial Statements, Note 12 - Derivative Instruments and Hedging Activities in the Notes to Unaudited Condensed Consolidated Financial Statements for additional discussion.

Foreign Currency Risk

Puerto Rico is a commonwealth territory under the U.S., and thus uses the U.S. dollar as its official currency.  BBH’s functional currency is the U.S. dollar and it is equivalent in value to the Bahamian dollar.  St. Lucia is a sovereign island country in the Caribbean and its official currency is the Eastern Caribbean dollar, which is pegged to the U.S. dollar and has remained fixed for many years.  The functional currency for our operations in St. Lucia is the U.S. dollar.  Foreign exchange gains and losses arising from transactions denominated in a currency other than the U.S. dollar relate to a nominal amount of supply purchases and are included in “Other (expense) income” within our unaudited condensed consolidated statements of operations. The effects of foreign currency transactions were not considered to be material for the three and six months ended June 30, 2019 and 2018.

Item 4.  Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer (the “CEO”) and Chief Financial Officer (the “CFO”), evaluated the design and effectiveness of our disclosure controls and procedures as of the end of the period covered by this Report.  Based on that evaluation, the CEO and CFO concluded that our disclosure controls and procedures as of the end of the period covered by this Report are designed and operating effectively to provide reasonable assurance that the information required to be disclosed by us in reports filed under the Securities Exchange Act of 1934, as amended, is: (i) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to management, including the CEO and CFO, as appropriate to allow timely decisions regarding disclosure.  A controls system cannot provide absolute assurance, however, that the objectives of the controls system are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.

Changes in Internal Control Over Financial Reporting

During the quarter ended June 30, 2019, there were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) or in other factors that materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

PART II.  OTHER INFORMATION

Item 1.  Legal Proceedings

In the ordinary course of business, we are involved in various claims and legal proceedings, some of which are covered by insurance. We are generally unable to predict the timing or outcome of these claims and proceedings. For information on unresolved legal proceedings, see Part I, Item 1, Financial Statements, Note 4 - Commitments and Contingencies in the Notes to Unaudited Condensed Consolidated Financial Statements included in this quarterly report, which is incorporated into this item by reference. In March 2019, we received a notice of probable violation from the Pipeline and Hazardous Materials Safety Administration (“PHMSA”) totaling approximately $0.7 million in connection with PHMSA’s 2017 integrated inspection of our pipelines located primarily in the northeastern United States.  We are contesting certain of the violations and requesting a reduced penalty. In April 2019, we received a Proposed Agreed Order from the Texas Commission for Environmental Quality (“TCEQ”) totaling approximately $0.6 million in connection with our non-compliance self-reporting as well as TCEQ’s inspection of the previous 4 years of operations in Corpus Christi, Texas.  At the time of this report there were no outstanding alleged violations for our operation in Corpus Christi, Texas.

Item 1A.  Risk Factors

Security holders and potential investors in our securities should carefully consider the risk factors set forth below and in Part II, “Item 1A. Risk Factors” of our Quarterly Report on form 10-Q for the quarterly period ended March 31, 2019 in addition to the risk factors in Part I, “Item 1A. Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2018. We have identified these risk factors as important factors that could cause our actual results to differ materially from those contained in any written or oral forward-looking statements made by us or on our behalf.

The tax treatment of publicly traded partnerships or an investment in our LP Units could be subject to potential legislative, judicial or administrative changes and differing interpretations, possibly on a retroactive basis.

The present U.S. federal income tax treatment of publicly traded partnerships, including us, or an investment in our LP Units may be modified by administrative, legislative or judicial interpretation at any time. From time to time, members of Congress have proposed and considered substantive changes to the existing U.S. federal income tax laws that would affect publicly traded partnerships, including the elimination of partnership tax treatment for publicly traded partnerships. For example, the “Clean Energy for America Act,” which is similar to legislation that was commonly proposed during the Obama Administration, was introduced in the Senate on May 2, 2019. If enacted, this proposal would, among other things, repeal Section 7704(d)(1)(E) of the Internal Revenue Code, upon which we rely for our status as a partnership for U.S. federal income tax purposes.

In addition, the Treasury Department has issued, and in the future may issue, regulations interpreting those laws that affect publicly traded partnerships. There can be no assurance that there will not be further changes to U.S. federal income tax laws or the Treasury Department’s interpretation of the qualifying income rules in a manner that could impact our ability to qualify as a partnership in the future. We believe the income that we treat as qualifying satisfies the requirements under current regulations.

We are unable to predict whether any changes or proposals will ultimately be enacted. Any modification to the U.S. federal income tax laws and interpretations thereof may or may not be retroactively applied and could make it more difficult or impossible for us to meet the exception to be treated as a partnership for U.S. federal income tax purposes and could negatively impact the value of an investment in our LP Units.

You are urged to consult with your own tax advisor with respect to the status of regulatory or administrative developments and proposals and their potential effect on your investment in our LP Units.
