NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1: Basis of Presentation

Boardwalk Pipeline Partners, LP (the Partnership) is a Delaware limited partnership formed in 2005 to own and operate the business conducted by its primary subsidiary Boardwalk Pipelines, LP (Boardwalk Pipelines) and its operating subsidiaries, which consists of integrated natural gas and natural gas liquids and other hydrocarbons (herein referred to together as NGLs) pipeline and storage systems.

As of July 28, 2017, Boardwalk Pipelines Holding Corp. (BPHC), a wholly-owned subsidiary of Loews Corporation (Loews), owned 125.6 million of the Partnership’s common units, and, through Boardwalk GP, LP (Boardwalk GP), an indirect wholly-owned subsidiary of BPHC, holds the 2% general partner interest and all of the incentive distribution rights (IDRs) of the Partnership. As of July 28, 2017, the common units and general partner interest owned by BPHC represent approximately 51% of the Partnership’s equity interests, excluding the IDRs. The Partnership’s common units are traded under the symbol “BWP” on the New York Stock Exchange.

The accompanying unaudited condensed consolidated financial statements of the Partnership were prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S.) (GAAP) have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments (consisting of only normal recurring accruals) necessary to present fairly the Partnership's financial position as of June 30, 2017, and December 31, 2016, and its results of operations and comprehensive income for the three and six months ended June 30, 2017 and 2016, and changes in cash flows and changes in partners' capital for the six months ended June 30, 2017 and 2016. Reference is made to the Notes to Consolidated Financial Statements in the Partnership's Annual Report on Form 10-K for the year ended December 31, 2016 (2016 Annual Report on Form 10-K), which should be read in conjunction with these unaudited condensed consolidated financial statements. The accounting policies described in Note 2 to the Consolidated Financial Statements included in the 2016 Annual Report on Form 10-K are the same used in preparing the accompanying unaudited condensed consolidated financial statements.

Net income for interim periods may not necessarily be indicative of results for the full year.

Note 2: Asset Disposition and Impairments

On May 9, 2017, the Partnership sold its Flag City Processing Partners, LLC subsidiary, which owns the Flag City processing plant and related assets, to a third party for approximately $64.7 million, including customary adjustments. The Partnership recorded losses and impairments, reported within Total Operating Costs and Expenses, of $47.1 million on the sale. The fair value measurements of the assets sold and impaired were based on Level 3 inputs under the fair value hierarchy.

Note 3: Gas and Liquids Stored Underground and Gas and NGLs Receivables and Payables

The operating subsidiaries of the Partnership provide storage services whereby they store natural gas or NGLs on behalf of customers and also periodically hold customer gas under parking and lending (PAL) services. Since the customers retain title to the gas held by the Partnership in providing these services, the Partnership does not record the related gas on its balance sheet.

The operating subsidiaries of the Partnership also periodically lend gas to customers under PAL and no-notice services (NNS), and gas or NGLs may be owed to the operating subsidiaries as a result of transportation imbalances. As of June 30, 2017, the amount of gas owed to the operating subsidiaries of the Partnership due to gas imbalances and gas loaned under PAL and NNS was approximately 11.0 trillion British thermal units (TBtu). Assuming an average market price during June 2017 of $2.85 per million British thermal unit, the market value of that gas was approximately $31.4 million. As of June 30, 2017, there were no outstanding NGLs imbalances owed to the operating subsidiaries. As of December 31, 2016, the amount of gas owed to the operating subsidiaries of the Partnership due to gas imbalances and gas loaned under PAL and NNS was approximately 13.6 TBtu. As of December 31, 2016, the amount of NGLs owed to the operating subsidiaries due to imbalances was less than 0.1 million barrels. If any significant customer should have credit or financial problems resulting in a delay or failure to repay the gas owed

to the operating subsidiaries, it could have a material adverse effect on the Partnership’s financial condition, results of operations or cash flows.

Note 4: Other Comprehensive Income (OCI) and Fair Value Measurements

OCI

The Partnership had no outstanding derivatives at June 30, 2017, and December 31, 2016, but had $6.2 million and $6.0 million of Accumulated other comprehensive income (loss) (AOCI) related to cash flow hedges as of June 30, 2017, and December 31, 2016, which relate to settled treasury rate locks that are being amortized to earnings over the terms of the related interest payments, generally the terms of the related debt. The Partnership estimates that approximately $2.0 million of net losses from cash flow hedges reported in AOCI as of June 30, 2017, are expected to be reclassified into earnings within the next twelve months.

The following table shows the components and reclassifications to net income of AOCI which is included in Partners' Capital on the Condensed Consolidated Balance Sheets for the three months ended June 30, 2017 (in millions):



	Cash Flow Hedges			Pension and Other Postretirement Costs			Total

Financial Assets and Liabilities

The following methods and assumptions were used in estimating the fair value amounts included in the disclosures for financial assets and liabilities, which are consistent with those disclosed in the 2016 Annual Report on Form 10-K:

Cash and Cash Equivalents: For cash and short-term financial assets, the carrying amount is a reasonable estimate of fair value due to the short maturity of those instruments.

Long-Term Debt: The estimated fair value of the Partnership's publicly traded debt is based on quoted market prices at June 30, 2017, and December 31, 2016. The fair market value of the debt that is not publicly traded is based on market prices of similar debt at June 30, 2017, and December 31, 2016. The Partnership had no variable-rate debt outstanding as of June 30, 2017. The carrying amount of the Partnership's variable-rate debt at December 31, 2016, approximated fair value.

The carrying amounts and estimated fair values of the Partnership's financial assets and liabilities which were not recorded at fair value on the Condensed Consolidated Balance Sheets as of June 30, 2017, and December 31, 2016, were as follows (in millions):



As of June 30, 2017				Estimated Fair Value
Financial Assets	Carrying Amount			Level 1		Level 2		Level 3		Total
Cash and cash equivalents	$	77.3		$	77.3	$	—	$	—	$	77.3

Financial Liabilities
Long-term debt	$	3,575.8	⁽¹⁾	$	—	$	3,777.2	$	—	$	3,777.2

(1) The carrying amount of long-term debt excludes an $8.4 million long-term capital lease obligation and

$9.7 million of unamortized debt issuance costs.



As of December 31, 2016				Estimated Fair Value
Financial Assets	Carrying Amount			Level 1		Level 2		Level 3		Total
Cash and cash equivalents	$	4.6		$	4.6	$	—	$	—	$	4.6

Financial Liabilities

(1) The carrying amount of long-term debt excludes an $8.6 million long-term capital lease obligation and

$9.5 million of unamortized debt issuance costs.

Note 5: Commitments and Contingencies

Legal Proceedings and Settlements

The Partnership's subsidiaries are parties to various legal actions arising in the normal course of business. Management believes the disposition of these outstanding legal actions will not have a material impact on the Partnership's financial condition, results of operations or cash flows. Refer to Note 4 of the Consolidated Financial Statements included in Part II, Item 8 of the Partnership's 2016 Annual Report on Form 10-K for further information regarding the Partnership’s legal proceedings.

Southeast Louisiana Flood Protection Litigation

The Partnership and its subsidiary, Gulf South Pipeline Company, LP, (Gulf South) along with approximately 100 other energy companies operating in Southern Louisiana, have been named as defendants in a petition for damages and injunctive relief in state district court for Orleans Parish, Louisiana, (Case No. 13-6911) by the Board of Commissioners of the Southeast Louisiana Flood Protection Authority - East (Flood Protection Authority). The case was filed in state court, but was removed to the U.S. District Court for the Eastern District of New Orleans (Court) in August 2013. The lawsuit claims include negligence, strict liability, public nuisance, private nuisance, breach of contract and breach of the natural servitude of drain against the defendants, alleging that the defendants’ drilling, dredging, pipeline and industrial operations since the 1930s have caused increased storm surge risk, increased flood protection costs and unspecified damages to the Flood Protection Authority. In addition to attorney fees and unspecified monetary damages, the lawsuit seeks abatement and restoration of the coastal lands, including backfilling and revegetating of canals dredged and used by the defendants, and abatement and restoration activities such as wetlands creation, reef creation, land bridge construction, hydrologic restoration, shoreline protection, structural protection, bank stabilization and ridge restoration. On February 13, 2015, the Court dismissed the case with prejudice. The Flood Protection Authority appealed the dismissal of the case to the U.S. Court of Appeals for the Fifth Circuit in May 2015 (Case No. 15-CV-30162). On March 3, 2017, the U.S. Court of Appeals for the Fifth Circuit upheld the Court’s dismissal. On April 12, 2017, the Fifth Circuit denied the Flood Protection Authorities' Petition for Rehearing En Banc. On July 11, 2017, the plaintiffs filed a writ of certiorari with the United States Supreme Court to review the case.

Settlements and Insurance Proceeds

In the second quarter 2016, the Partnership received $12.7 million in cash from the settlement of a legal claim which was recorded in Transportation revenues.

Environmental and Safety Matters

The operating subsidiaries are subject to federal, state and local environmental laws and regulations in connection with the operation and remediation of various operating sites. As of June 30, 2017, and December 31, 2016, the Partnership had an accrued liability of approximately $4.5 million and $5.0 million related to assessment and/or remediation costs associated with the historical use of polychlorinated biphenyls, petroleum hydrocarbons and mercury. The liability represents management’s estimate of the undiscounted future obligations based on evaluations and discussions with counsel and operating personnel and the current facts and circumstances related to these matters. The related expenditures are expected to occur over the next five years. As of June 30, 2017, and December 31, 2016, approximately $1.7 million was recorded in Other current liabilities for each period and approximately $2.8 million and $3.3 million were recorded in Other Liabilities and Deferred Credits.

Commitments for Construction

The Partnership’s future capital commitments are comprised of binding commitments under purchase orders for materials ordered but not received and firm commitments under binding construction service agreements. The commitments as of June 30, 2017, were approximately $290.8 million, all of which are expected to be settled within the next twelve months.

There were no substantial changes to the Partnership’s operating lease commitments, pipeline capacity agreements or capital lease obligation disclosed in Notes 4 and 10 to the Partnership’s 2016 Annual Report on Form 10-K.

Note 6: Cash Distributions and Net Income per Unit

Cash Distributions

In the second quarters 2017 and 2016, the Partnership declared and paid quarterly distributions to its common unitholders of record of $0.10 per common unit and an amount to the general partner on behalf of its 2% general partner interest. In July 2017, the Partnership declared a quarterly cash distribution to unitholders of record of $0.10 per common unit.

Net Income per Unit

For purposes of calculating net income per unit, net income for the current period is reduced by the amount of available cash that will be distributed with respect to that period. Payments made on account of the Partnership’s various ownership interests are determined in relation to actual declared distributions, and are not based on the assumed allocations required under GAAP. Any residual amount representing undistributed net income (or loss) is assumed to be allocated to the various ownership interests in accordance with the contractual provisions of the partnership agreement on a pro rata basis. Net income per unit is calculated based on the weighted-average number of units outstanding for the period.

The following table provides a reconciliation of net income and the assumed allocation of net income to the common units for purposes of computing net income per unit for the three months ended June 30, 2017 (in millions, except per unit data):



	Total			Common Units			General Partner and IDRs

Note 7: Financing

Notes and Debentures

As of June 30, 2017, and December 31, 2016, the Partnership had notes and debentures outstanding of $3.6 billion and $3.4 billion with weighted-average interest rates of 5.29% and 5.46%. The indentures governing the notes and debentures have restrictive covenants which provide that, with certain exceptions, neither the Partnership nor any of its subsidiaries may create, assume or suffer to exist any lien upon any property to secure any indebtedness unless the debentures and notes shall be equally and ratably secured. All of the Partnership's debt obligations are unsecured. At June 30, 2017, Boardwalk Pipelines and its operating subsidiaries were in compliance with their debt covenants.

The Partnership has included $460.0 million of notes which mature in less than one year as long-term debt on its Condensed Consolidated Balance Sheet as of June 30, 2017. The Partnership has the intent and the ability to refinance the notes through the available borrowing capacity under its revolving credit facility as of June 30, 2017. The Partnership expects to retire these notes at their maturity.

Issuance of Notes

For the six months ended June 30, 2017 and 2016, the Partnership completed the following debt issuances (in millions, except interest rates):



Date of Issuance	Issuing Subsidiary	Amount of Issuance		Purchaser Discounts and Expenses		Net Proceeds			Interest Rate	Maturity Date	Interest Payable
January 2017	Boardwalk Pipelines	$	500.0	$	6.0	$	494.0	⁽¹⁾	4.45%	July 15, 2027	January 15 and July 15
May 2016	Boardwalk Pipelines	$	550.0	$	10.9	$	539.1	⁽²⁾	5.95%	June 1, 2026	June 1 and December 1

(1) The net proceeds of this offering will be used to refinance future maturities of debt and to fund growth capital expenditures. Initially, the proceeds were used to reduce outstanding borrowings under the revolving credit facility.

(2) The net proceeds of this offering were used to retire the outstanding $250.0 million aggregate principal amount of Boardwalk Pipelines 5.875% notes due 2016 and the outstanding $300.0 million aggregate principal amount of Boardwalk Pipelines 5.50% notes due 2017 at their maturity. Initially, the Partnership used the net proceeds to reduce outstanding borrowings under its revolving credit facility.

Revolving Credit Facility

As of June 30, 2017, the Partnership had no outstanding borrowings under its revolving credit facility. Outstanding borrowings under the Partnership’s revolving credit facility as of December 31, 2016, were $180.0 million with a weighted-average borrowing rate of 1.96%. The Partnership and its subsidiaries were in compliance with all covenant requirements under the revolving credit facility as of June 30, 2017. In July 2017, the Partnership extended the maturity date of the revolving credit facility by one additional year to May 26, 2022. The borrowing capacity of the revolving credit facility is $1.475 billion for the first extension period of May 27, 2020, to May 26, 2021, and $1.393 billion for the second extension period of May 27, 2021, to May 26, 2022, as certain banks elected to not participate in the extensions.

Subordinated Loan Agreement with Affiliate

The Partnership has in place a Subordinated Loan Agreement with BPHC (Subordinated Loan) under which the Partnership can borrow up to $300.0 million through December 31, 2018. Through the date of this Report, the Partnership had no outstanding borrowings under the Subordinated Loan.

Note 11: Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606), (ASU 2014-09) which will require entities to recognize revenue in an amount that reflects the transfer of promised goods or services to a customer in an amount based on the consideration the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 also requires disclosures regarding the nature, amount, timing and uncertainty of revenues and cash flows from contracts with customers. The amendments may be applied retrospectively to each prior period presented, or retrospectively with the cumulative effect recognized as of the date of initial application. ASU 2014-09 is effective for interim and annual reporting periods beginning after December 15, 2017. The Partnership has substantially completed a review of its contracts with customers in relation to the requirements of ASU 2014-09, and has tentatively concluded that the implementation of ASU 2014-09 will not have a material impact on its revenue recognition policies for a substantial number of its contracts. However, certain items remain outstanding that could change those conclusions. The Partnership is working with an industry group to develop positions regarding those outstanding items. The Partnership intends to apply ASU 2014-09 to its financial statements retrospectively with the cumulative effect of implementation recognized as of January 1, 2018.

In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases (Topic 842) (ASU 2016-02), which will require, among other things, the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under current GAAP. The amendments are to be applied at the beginning of the earliest period presented using a modified retrospective approach. ASU 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018, however, early adoption is permitted. The Partnership has initiated a project to evaluate the impact that ASU 2016-02 will have on its financial statements when implemented, however, no conclusions have been reached.

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

The following discussion and analysis of financial condition and results of operations should be read in conjunction with our accompanying interim condensed consolidated financial statements and related notes, included elsewhere in this report and prepared in accordance with accounting principles generally accepted in the United States of America and our consolidated financial statements, related notes, Management's Discussion and Analysis of Financial Condition and Results of Operations and Risk Factors included in our Annual Report on Form 10-K for the year ended December 31, 2016 (2016 Annual Report on Form 10-K).

Firm Transportation Contracts and Growth Projects

Each year a portion of our firm transportation agreements expire and need to be renewed or replaced. In the 2018 to 2020 timeframe, the agreements associated with our East Texas Pipeline, Southeast Expansion, Gulf Crossing Pipeline and Fayetteville and Greenville Laterals, which were placed into service in 2008 and 2009, will expire. These projects were large, new pipeline expansions, developed to serve growing production in Texas, Oklahoma, Arkansas and Louisiana and anchored primarily by 10-year firm transportation agreements with producers. Since our expansion projects went into service, gas production from the Utica and Marcellus area in the Northeast has grown significantly and has altered the flow patterns of natural gas in North America. Over the last few years, gas production from other basins such as Barnett and Fayetteville, which primarily supported two of our expansions, has declined because the production economics in those basins are not as competitive as other production basins, such as Utica and Marcellus. These market dynamics have resulted in less production from certain basins tied to our system and a narrowing of basis differentials across portions of our pipeline systems, primarily for capacity associated with natural gas flows from west to east. We expect that the total revenues generated from the expansion project capacity could be materially lower when these contracts expire. Our marketing efforts are focused on enhancing the value of the expansion capacity. We are working with customers to match gas supplies from various basins to new and existing customers and markets, including aggregating supplies at key locations along our pipelines to provide end-use customers with attractive and diverse supply options.

Partly as a result of the increase in overall gas supplies, demand markets, primarily in the Gulf Coast area, are growing due to new natural gas export facilities, power plants, petrochemical facilities and increased exports to Mexico. These developments have resulted in significant growth projects for us, several of which we placed into service during 2016. These include the Ohio to Louisiana Access project, the Southern Indiana Lateral, the Western Kentucky Market Lateral, a project to serve a power plant in South Texas, and in March 2017, the Northern Supply Access Project. We have an additional $1.1 billion of growth projects under development that are expected to be placed into service in 2017 through 2019, and through June 30, 2017, we have invested $424.6 million of capital in these projects. These new projects have lengthy planning and construction periods. As a result, these projects will not contribute to our earnings and cash flows until they are placed into service over the next several years.

Results of Operations

On May 9, 2017, we sold our Flag City Processing Partners, LLC subsidiary, which owns the Flag City processing plant and related assets, to a third party for approximately $64.7 million, including customary adjustments. We recorded losses and impairments, reported within Total Operating Costs and Expenses, of $47.1 million on the sale.

Effective April 1, 2016, Gulf South Pipeline Company, LP (Gulf South) implemented a fuel tracker. Fuel received from customers paying the full tariff rate and the related value of fuel used in transportation are recorded as a net regulatory asset or liability on the balance sheet. Had the fuel tracker been implemented January 1, 2016, operating revenues would have been lower by $5.0 million and fuel and transportation expense would have been lower by $4.0 million for the six months ended June 30, 2016. Refer to our 2016 Annual Report on Form 10-K for more information.

Results of Operations for the Three Months Ended June 30, 2017 and 2016

Our net income for the three months ended June 30, 2017, decreased $42.0 million, or 64%, to $23.7 million compared to $65.7 million for the three months ended June 30, 2016, primarily due to the sale of the Flag City processing plant and related assets in the second quarter of 2017 and $12.7 million of income from the settlement of a legal claim in the second quarter of 2016.

Operating revenues for the three months ended June 30, 2017, increased $11.3 million, or 4%, to $317.6 million, compared to $306.3 million for the three months ended June 30, 2016. Excluding the net effect of the 2016 legal settlement and items offset in fuel and transportation expense, primarily retained fuel, operating revenues increased $21.1 million, or 7%. The increase was driven by an increase in transportation revenues of $19.6 million, which resulted from growth projects recently placed into service, partly offset by contract expirations.

Operating costs and expenses for the three months ended June 30, 2017, increased $53.4 million, or 27%, to $250.4 million, compared to $197.0 million for the three months ended June 30, 2016. Excluding items offset in operating revenues and the $47.1 million loss on the sale of Flag City assets, operating costs and expenses increased $3.4 million, or 2% when compared to the comparable period in 2016. The operating expense increase was primarily due to an increase in maintenance activities.

Total other deductions for the three months ended June 30, 2017, decreased $0.3 million, or less than 1%, to $43.1 million compared to $43.4 million for the 2016 period.

Results of Operations for the Six Months Ended June 30, 2017 and 2016

Our net income for the six months ended June 30, 2017, decreased $23.7 million, or 14%, to $143.0 million compared to $166.7 million for the six months ended June 30, 2016, primarily due to the sale of the Flag City processing plant and related assets in the second quarter of 2017 and $12.7 million of income from the settlement of a legal claim in the second quarter of 2016.

Operating revenues for the six months ended June 30, 2017, increased $33.3 million, or 5%, to $684.6 million, compared to $651.3 million for the six months ended June 30, 2016. Excluding the net effect of the 2016 legal settlement and items offset in fuel and transportation expense, primarily retained fuel, operating revenues increased $44.2 million, or 7%. The increase was driven by an increase in transportation revenues of $35.4 million, which resulted from growth projects recently placed into service. Storage and PAL revenues were higher by $3.5 million primarily from the effects of favorable market conditions on time period price spreads.

Operating costs and expenses for the six months ended June 30, 2017, increased $52.2 million, or 13%, to $452.6 million, compared to $400.4 million for the six months ended June 30, 2016. Excluding items offset in operating revenues and the $47.1 million loss on the sale of Flag City assets, operating costs and expenses increased $3.3 million, or less than 1% when compared to the comparable period in 2016.

Total other deductions for the six months ended June 30, 2017, increased $4.6 million, or 5%, to $88.4 million compared to $83.8 million for the 2016 period. The increase in total other deductions was primarily a result of an increase in interest expense due to higher average debt levels at higher borrowing rates.

Liquidity and Capital Resources

We anticipate that our existing capital resources, including our revolving credit facility, Subordinated Loan Agreement with Boardwalk Pipelines Holding Corp. and our cash flows from operating activities, will be adequate to fund our operations for 2017. We may seek to access the capital markets to fund some or all capital expenditures for growth projects, acquisitions or for general partnership purposes. Our ability to access the capital markets for equity and debt financing under reasonable terms depends on our financial condition, credit ratings and market conditions.

In July 2017, we extended the maturity date of our revolving credit facility by one additional year to May 26, 2022. The borrowing capacity of the revolving credit facility is $1.475 billion for the first extension period of May 27, 2020, to May 26, 2021, and $1.393 billion for the second extension period of May 27, 2021, to May 26, 2022, as certain banks elected to not participate in the extensions. In January 2017, we received net proceeds of approximately $494.0 million from the issuance of $500.0 million aggregate principal amount of Boardwalk Pipelines, LP 4.45% notes due in July 2027. The proceeds from this offering will be used to refinance future maturities of debt and to fund growth capital expenditures. Initially, the proceeds were used to reduce outstanding borrowings under the revolving credit facility.

Capital Expenditures

Maintenance capital expenditures for the six months ended June 30, 2017 and 2016, were $44.4 million and $41.4 million. Growth capital expenditures were $258.4 million and $217.6 million for the six months ended June 30, 2017 and 2016. We expect total capital expenditures to be approximately $790.0 million in 2017, including approximately $140.0 million for maintenance capital and $650.0 million related to growth projects. This reflects a $60.0 million reduction in our expected growth capital expenditures for 2017, resulting from both a delay in the timing of the expenditures and an overall reduction in spending.

Contractual Obligations

Our principal debt obligations at June 30, 2017, and December 31, 2016, were $3.6 billion. Refer to Note 7 in Part I, Item 1 of this Report and our 2016 Annual Report on Form 10-K for more information on our financing activities and debt obligations.

Distributions

For each of the six months ended June 30, 2017 and 2016, we paid distributions of $51.1 million to our partners. Note 6 in Part I, Item 1 of this Report contains further discussion regarding our distributions. Our distribution policy may be changed at any time and is subject to certain restrictions or limitations. Refer to Part II, Item 5 of our 2016 Annual Report on Form 10-K for our full distribution policy and risks associated with it.

Changes in cash flow from operating activities

Net cash provided by operating activities, excluding the effects of non-cash items such as depreciation, amortization and the loss on the sale of operating assets, increased $43.2 million to $347.9 million for the six months ended June 30, 2017, compared to $304.7 million for the comparable 2016 period primarily due to the change in net income and the 2016 settlement of the Gulf South rate refund.

Changes in cash flow from investing activities

Net cash used in investing activities decreased $20.9 million to $238.0 million for the six months ended June 30, 2017, compared to $258.9 million for the comparable 2016 period. The decrease was driven by the proceeds received from the sale of the Flag City processing plant and related assets of $64.7 million, partially offset by an increase in capital expenditures of $43.8 million related to our growth projects.

Changes in cash flow from financing activities

Net cash used in financing activities increased $150.1 million to $37.2 million for the six months ended June 30, 2017, compared to $112.9 million cash provided for the comparable 2016 period. The increase resulted primarily from the refinancing of maturing debt, which proceeds were initially used to reduce borrowings under the revolving credit facility.

Off-Balance Sheet Arrangements

At June 30, 2017, we had no guarantees of off-balance sheet debt to third parties, no debt obligations that contain provisions requiring accelerated payment of the related obligations in the event of specified levels of declines in credit ratings and no other off-balance sheet arrangements.

Critical Accounting Policies

Certain amounts included in or affecting our unaudited condensed consolidated financial statements and related disclosures must be estimated, requiring us to make certain judgments and assumptions with respect to values or conditions that cannot be known with certainty at the time the financial statements are prepared. These estimates and judgments affect the reported amounts for assets, liabilities, revenues, expenses and our disclosure of contingent assets and liabilities in our financial statements. We evaluate these estimates and judgments on an ongoing basis, utilizing historical experience, consultation with third parties and other methods we consider reasonable. Nevertheless, actual results may differ significantly from our estimates. Any effects on our business, financial position or results of operations resulting from revisions to these estimates are recorded in the periods in which the facts that give rise to the revisions become known.

During 2017, there have been no significant changes to our critical accounting policies, judgments or estimates disclosed in our 2016 Annual Report on Form 10-K.

Forward-Looking Statements

Investors are cautioned that certain statements contained in this Report, as well as some statements in periodic press releases and some oral statements made by our officials and our subsidiaries during presentations about us, are “forward-looking.” Forward-looking statements include, without limitation, any statement that may project, indicate or imply future results, events, performance or achievements, and may contain the words “expect,” “intend,” “plan,” “anticipate,” “estimate,” “believe,” “will likely result” and similar expressions. In addition, any statement made by our management concerning future financial performance (including future revenues, earnings or growth rates), ongoing business strategies or prospects and possible actions by our partnership or our subsidiaries, are also forward-looking statements.

Forward-looking statements are based on current expectations and projections about future events and their potential impact on us. While management believes that these forward-looking statements are reasonable as and when made, there is no assurance that future events affecting us will be those that we anticipate. All forward-looking statements are inherently subject to a variety of risks and uncertainties, many of which are beyond our control which could cause actual results to differ materially from those anticipated or projected. These include, among others, risks and uncertainties related to our ability to maintain or replace expiring gas transportation and storage contracts, our ability to complete projects that we have commenced or will commence, the impact of changes to laws and regulations, the costs of maintaining and ensuring the integrity and reliability of our pipeline systems, successful negotiation, consummation and completion of contemplated transactions, projects and agreements, to contract and physically make our systems bi-directional, and to sell short-term capacity on our pipelines.

Refer to Part I, Item 1A and Part II, Item 7 of our 2016 Annual Report on Form 10-K for additional risks and uncertainties regarding our forward-looking statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Refer to Part II, Item 7A of our 2016 Annual Report on Form 10-K, for discussion of our market risk.

Item 4. Controls and Procedures
