ONEOK, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A.
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Our accompanying unaudited consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC. These statements have been prepared in accordance with GAAP and reflect all adjustments that, in our opinion, are necessary for a fair statement of the results for the interim periods presented. All such adjustments are of a normal recurring nature. The 2015 year-end consolidated balance sheet data was derived from our audited financial statements but does not include all disclosures required by GAAP. Certain reclassifications have been made in the prior-year financial statements to conform to the current-year presentation. These unaudited consolidated financial statements should be read in conjunction with our audited consolidated financial statements in our Annual Report.

Unless indicated otherwise, the information in the Notes to the Consolidated Financial Statements relates to our continuing operations.

Our significant accounting policies are consistent with those disclosed in Note A of the Notes to Consolidated Financial Statements in our Annual Report, except as described below.

Consolidation - Our consolidated financial statements include our accounts and the accounts of our subsidiaries over which we have control or are the primary beneficiary. Management’s judgment is required when:
determining whether an entity is a variable interest entity (VIE);
determining whether we are the primary beneficiary of a VIE; and
identifying events that require reconsideration of whether an entity is a VIE.

As a result of adopting ASU 2015-02 described below, we have concluded that ONEOK Partners is a VIE and that we are the primary beneficiary. Therefore, we continue to consolidate ONEOK Partners. See Note K for additional information.

We record noncontrolling interests in consolidated subsidiaries on our Consolidated Balance Sheets to recognize the portion of ONEOK Partners that we do not own. We reflect our ownership interest in ONEOK Partners’ accumulated other comprehensive income (loss) in our consolidated accumulated other comprehensive income (loss). The remaining portion is reflected as an adjustment to noncontrolling interests in consolidated subsidiaries.

Recently Issued Accounting Standards Update - In September 2015, the FASB issued ASU 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments,” which requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendment also requires the acquirer to record the income statement effects of changes to provisional amounts in the financial statements in the period in which the adjustments occurred. This guidance was effective for public companies for fiscal years beginning after December 15, 2015. We adopted this guidance in the first quarter 2016, and there was no impact, but it could impact us in the future if we complete any acquisitions with subsequent measurement period adjustments.

In May 2015, the FASB issued ASU 2015-07, “Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent),” which removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The amendment also removes the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. This guidance was effective for public companies for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. We adopted this guidance in the first quarter 2016. The impact of adopting this guidance was not material.

In April 2015, the FASB issued ASU 2015-05, “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement,” which clarifies whether a cloud computing arrangement includes a software license. If it does, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses; if not, the customer should account for the arrangement as a service contract. This guidance was effective for public companies for fiscal years beginning after December 15, 2015. We adopted this guidance in the first quarter 2016. The impact of adopting this guidance was not material.

Table of Contents

In February 2015, the FASB issued ASU 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis,” which eliminates the presumption that a general partner should consolidate a limited partnership. It also modifies the evaluation of whether limited partnerships are variable interest entities or voting interest entities and adds requirements that limited partnerships must meet to qualify as voting interest entities. This guidance was effective for public companies for fiscal years beginning after December 15, 2015. We adopted this guidance in the first quarter 2016. As a result of adopting this guidance, we no longer consolidate ONEOK Partners under the presumption that a general partner should consolidate a limited partnership. We concluded, however, that ONEOK Partners is a VIE and ONEOK is the primary beneficiary, and we therefore consolidate ONEOK Partners under the variable interest model of consolidation. There was no financial statement impact due to the change in consolidation methodology. See Note K for additional information.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” which requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented net of the allowance for credit losses to reflect the net carrying value at the amount expected to be collected on the financial asset; and the initial allowance for credit losses for purchased financial assets, including available-for-sale debt securities, to be added to the purchase price rather than being reported as a credit loss expense. This guidance is effective for public companies for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for the fiscal years beginning after December 15, 2018. We expect to adopt this guidance in the first quarter 2020, and we are evaluating the impact on us.

In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting,” which provides simplified accounting for share-based payment transactions in relation to income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This guidance is effective for public companies for annual periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted. We expect to adopt this guidance in the first quarter 2017, and we are evaluating the impact on us.

In March 2016, the FASB issued ASU 2016-06, “Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments,” which clarifies the requirements for assessing whether a contingent call (put) option that can accelerate the payment of principal on a debt instrument is clearly and closely related to its debt host. Under the amendments in the update, assessments must be performed in accordance with the four-step decision sequence to conclude which call (put) options should be bifurcated and accounted for separately as derivatives. This guidance is effective for public companies for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years, with early adoption permitted. We expect to adopt this guidance in the first quarter 2017, and we are evaluating the impact on us.

In March 2016, the FASB issued ASU 2016-05, “Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships,” which clarifies that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under Topic 815 does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. This guidance is effective for public companies for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. We expect to adopt this guidance in the first quarter 2017, and we are evaluating the impact on us.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” which requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. It also requires qualitative disclosures along with specific quantitative disclosures by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. This guidance is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We expect to adopt this guidance in the first quarter 2019, and we are evaluating the impact on us.

In January 2016, the FASB issued ASU 2016-01, “Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities,” which requires all equity investments other than those accounted for using the equity method of accounting or those that result in consolidation of the investee to be measured at fair value with changes in fair value recognized in net income, eliminates the available-for-sale classification for equity securities with readily determinable fair values and eliminates the cost method for equity investments without readily determinable fair values. Additionally, this guidance eliminates the requirement to disclose the methods and significant assumptions used to estimate the fair value of financial instruments carried at amortized cost and requires the use of the exit price when measuring the fair value of such instruments for disclosure purposes. This guidance will be effective for public companies in fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is only permitted for certain portions of the ASU. We expect to adopt this guidance in the first quarter 2018, and we are evaluating the impact on us.

Table of Contents

In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory,” which requires that inventory, excluding inventory measured using last-in, first-out (LIFO) or the retail inventory method, be measured at the lower of cost or net realizable value. This guidance will be effective for public companies for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. We expect to adopt this guidance in the first quarter 2017, and we are evaluating the impact on us.

In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” which provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements. The new standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. An entity must provide certain disclosures if conditions or events raise substantial doubt about the entity’s ability to continue as a going concern. The standard applies to all entities and is effective for annual periods ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. We expect to adopt this guidance beginning in the fourth quarter 2016, and we do not expect it to materially impact us.

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which outlines the principles an entity must apply to measure and recognize revenue for entities that enter into contracts to provide goods or services to their customers. The core principle is that an entity should recognize revenue at an amount that reflects the consideration to which the entity expects to be entitled in exchange for transferring goods or services to a customer. The amendment also requires more extensive disaggregated revenue disclosures in interim and annual financial statements. In August 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,” that deferred the effective date of ASU 2014-09 by one year. This update is now effective for interim and annual periods that begin after December 15, 2017, with either retrospective application for all periods presented or retrospective application with a cumulative effect adjustment. The FASB has issued additional ASUs, which provide further guidance and clarification on implementation issues. We expect to adopt this guidance beginning in the first quarter 2018, and we are evaluating the impact on us.

B.
FAIR VALUE MEASUREMENTS

Determining Fair Value - We define fair value as the price that would be received from the sale of an asset or the transfer of a liability in an orderly transaction between market participants at the measurement date. We use market and income approaches to determine the fair value of our assets and liabilities and consider the markets in which the transactions are executed. We measure the fair value of a group of financial assets and liabilities consistent with how a market participant would price the net risk exposure at the measurement date.

While many of the contracts in our portfolio are executed in liquid markets where price transparency exists, some contracts are executed in markets for which market prices may exist, but the market may be relatively inactive. This results in limited price transparency that requires management’s judgment and assumptions to estimate fair values. For certain transactions, we utilize modeling techniques using NYMEX-settled pricing data and implied forward LIBOR curves. Inputs into our fair value estimates include commodity-exchange prices, over-the-counter quotes, historical correlations of pricing data, data obtained from third-party pricing services and LIBOR and other liquid money-market instrument rates. We validate our valuation inputs with third-party information and settlement prices from other sources, where available.

In addition, as prescribed by the income approach, we compute the fair value of derivatives by discounting the projected future cash flows from the derivative assets and liabilities to present value using interest-rate yields to calculate present-value discount factors derived from LIBOR, Eurodollar futures and the LIBOR interest-rate swaps market. We also take into consideration the potential impact on market prices of liquidating positions in an orderly manner over a reasonable period of time under current market conditions. We consider current market data in evaluating counterparties’, as well as our own, nonperformance risk, net of collateral, by using specific and sector bond yields and monitoring the credit default swap markets. Although we use our best estimates to determine the fair value of the executed derivative contracts , the ultimate market prices realized could differ from our estimates, and the differences could be material.

The fair value of forward-starting interest-rate swaps are determined using financial models that incorporate the implied forward LIBOR yield curve for the same period as the future interest-rate swap settlements.

Table of Contents

Fair Value Hierarchy - At each balance sheet date, we utilize a fair value hierarchy to classify fair value amounts recognized or disclosed in our financial statements based on the observability of inputs used to estimate such fair value. The levels of the hierarchy are described below:
Level 1 - fair value measurements are based on unadjusted quoted prices for identical securities in active markets, including NYMEX-settled prices. These balances are comprised predominantly of exchange-traded derivative contracts for natural gas and crude oil.
Level 2 - fair value measurements are based on significant observable pricing inputs, such as NYMEX-settled prices for natural gas and crude oil, and financial models that utilize implied forward LIBOR yield curves for interest-rate swaps.
Level 3 - fair value measurements are based on inputs that may include one or more unobservable inputs, including internally developed natural gas basis and NGL price curves that incorporate observable and unobservable market data from broker quotes, third-party pricing services, market volatilities derived from the most recent NYMEX close spot prices and forward LIBOR curves, and adjustments for the credit risk of our counterparties. We corroborate the data on which our fair value estimates are based using our market knowledge of recent transactions, analysis of historical correlations and validation with independent broker quotes. These balances categorized as Level 3 are comprised of derivatives for natural gas and NGLs. We do not believe that our Level 3 fair value estimates have a material impact on our results of operations, as the majority of our derivatives are accounted for as hedges for which ineffectiveness has not been material.

Determining the appropriate classification of our fair value measurements within the fair value hierarchy requires management’s judgment regarding the degree to which market data is observable or corroborated by observable market data. We categorize derivatives for which fair value is determined using multiple inputs within a single level, based on the lowest level input that is significant to the fair value measurement in its entirety.

(a) - Derivative assets and liabilities are presented in our Consolidated Balance Sheets on a net basis. We net derivative assets and liabilities when a legally enforceable master-netting arrangement exists between the counterparty to a derivative contract and us. At June 30, 2016, we had no cash held and posted $33.5 million of cash with various counterparties, including $16.7 million of cash collateral that is offsetting derivative net liability positions under master-netting arrangements in the table above. The remaining $16.8 million of cash collateral in excess of derivative net liability positions is included in other current assets in our Consolidated Balance Sheets.
(b) - Included in other current assets, other assets, other current liabilities or deferred credits and other liabilities in our Consolidated Balance Sheets.

(a) - Derivative assets and liabilities are presented in our Consolidated Balance Sheets on a net basis. We net derivative assets and liabilities when a legally enforceable master-netting arrangement exists between the counterparty to a derivative contract and us. At December 31, 2015, we held $34.4 million of cash from various counterparties that is offsetting derivative net asset positions in the table above under master-netting arrangements and had no cash collateral posted.
(b) - Included in other current assets or other current liabilities in our Consolidated Balance Sheets.

(a) - Included in commodity sales revenues in our Consolidated Statements of Income.

Realized/unrealized gains (losses) include the realization of derivative contracts through maturity. During the three and six months ended June 30, 2016 and 2015, gains or losses included in earnings attributable to the change in unrealized gains or losses relating to assets and liabilities still held at the end of each reporting period were not material.

We recognize transfers into and out of the levels in the fair value hierarchy as of the end of each reporting period. During the three and six months ended June 30, 2016 and 2015, there were no transfers between levels.

Other Financial Instruments - The approximate fair value of cash and cash equivalents, accounts receivable, accounts payable and short-term borrowings is equal to book value, due to the short-term nature of these items. Our cash and cash equivalents are comprised of bank and money market accounts and are classified as Level 1. Our short-term borrowings are classified as Level 2 since the estimated fair value of the short-term borrowings can be determined using information available in the commercial paper market.

The estimated fair value of our consolidated long-term debt, including current maturities, was $9.0 billion and $7.4 billion at June 30, 2016, and December 31, 2015, respectively. The book value of our consolidated long-term debt, including current maturities, was $8.8 billion and $8.4 billion at June 30, 2016, and December 31, 2015, respectively. The estimated fair value of the aggregate of ONEOK’s and ONEOK Partners’ senior notes outstanding was determined using quoted market prices for similar issues with similar terms and maturities. The estimated fair value of our consolidated long-term debt is classified as Level 2.

C.
RISK-MANAGEMENT AND HEDGING ACTIVITIES USING DERIVATIVES

Risk-Management Activities - We are sensitive to changes in natural gas, crude oil and NGL prices, principally as a result of contractual terms under which these commodities are processed, purchased and sold. We use physical-forward purchases and

18

Table of Contents

sales and financial derivatives to secure a certain price for a portion of its natural gas, condensate and NGL products; to reduce its exposure to commodity price and interest-rate fluctuations; and to achieve more predictable cash flows. We follow established policies and procedures to assess risk and approve, monitor and report risk-management activities. We have not used these instruments for trading purposes. We are also subject to the risk of interest-rate fluctuation in the normal course of business.

Commodity price risk - Commodity price risk refers to the risk of loss in cash flows and future earnings arising from adverse changes in the price of natural gas, NGLs and condensate. We use the following commodity derivative instruments to mitigate the near-term commodity price risk associated with a portion of the forecasted sales of these commodities:
Futures contracts - Standardized contracts to purchase or sell natural gas and crude oil for future delivery or settlement under the provisions of exchange regulations;
Forward contracts - Nonstandardized commitments between two parties to purchase or sell natural gas, crude oil or NGLs for future physical delivery. These contracts are typically nontransferable and can only be canceled with the consent of both parties;
Swaps - Exchange of one or more payments based on the value of one or more commodities. These instruments transfer the financial risk associated with a future change in value between the counterparties of the transaction, without also conveying ownership interest in the asset or liability; and
Options - Contractual agreements that give the holder the right, but not the obligation, to buy or sell a fixed quantity of a commodity at a fixed price within a specified period of time. Options may either be standardized and exchange-traded or customized and nonexchange-traded.

We may also use other instruments including collars to mitigate commodity price risk. A collar is a combination of a purchased put option and a sold call option, which places a floor and a ceiling price for commodity sales being hedged.

The Natural Gas Gathering and Processing segment is exposed to commodity price risk as a result of receiving commodities as a portion of its compensation for services associated with its POP with fee contracts. Under certain POP with fee contracts, ONEOK Partners’ fee revenues may increase or decrease if production volumes, delivery pressures or commodity prices change relative to specified thresholds. The Natural Gas Gathering and Processing segment also is exposed to basis risk between the various production and market locations where it receives and sells commodities. As part of our hedging strategy, we use the previously described commodity derivative financial instruments and physical-forward contracts to reduce the impact of price fluctuations related to natural gas, NGLs and condensate.

The Natural Gas Liquids segment is exposed to location price differential risk, primarily as a result of the relative value of NGL purchases at one location and sales at another location. The Natural Gas Liquids segment also is exposed to commodity price risk resulting from the relative values of the various NGL products to each other, NGLs in storage and the relative value of NGLs to natural gas. We utilize physical-forward contracts and commodity derivative financial instruments to reduce the impact of price fluctuations related to NGLs.

The Natural Gas Pipelines segment is exposed to commodity price risk because its intrastate and interstate natural gas pipelines retain natural gas from its customers for operations or as part of its fee for services provided. When the amount of natural gas consumed in operations by these pipelines differs from the amount provided by its customers, our pipelines must buy or sell natural gas, or store or use natural gas from inventory, which can expose it to commodity price risk depending on the regulatory treatment for this activity. To the extent that commodity price risk in the Natural Gas Pipelines segment is not mitigated by fuel cost-recovery mechanisms, we use physical-forward sales or purchases to reduce the impact of price fluctuations related to natural gas. At June 30, 2016, and December 31, 2015, there were no financial derivative instruments with respect to ONEOK Partners’ natural gas pipeline operations.

Interest-rate risk - We manage interest-rate risk through the use of fixed-rate debt, floating-rate debt and interest-rate swaps. Interest-rate swaps are agreements to exchange interest payments at some future point based on specified notional amounts. As of June 30, 2016, ONEOK Partners had interest-rate swaps with notional amounts totaling $1.0 billion to hedge the variability of ONEOK Partners’ LIBOR-based interest payments. In June 2016, ONEOK Partners entered into forward-starting interest-rate swaps with notional amounts totaling $750 million to hedge the variability of interest payments on a portion of its forecasted debt issuances that may result from changes in the benchmark interest rate before the debt is issued. At June 30, 2016, and December 31, 2015, ONEOK Partners had forward-starting interest-rate swaps with notional amounts totaling $1.2 billion and $400 million, respectively, to hedge the variability of interest payments on a portion of its forecasted debt issuances. All of ONEOK Partners’ interest-rate swaps are designated as cash flow hedges.

Accounting Treatment - All derivative instruments are recorded at fair value, with the exception of normal purchases and normal sales transactions that are expected to result in physical delivery. Commodity price and interest-rate volatility may have a significant impact on the fair value of derivative instruments as of a given date. The accounting for changes in the fair value of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, if so, the reason for holding it.

The table below summarizes the various ways in which we account for our derivative instruments and the impact on our consolidated financial statements:

To reduce our exposure to fluctuations in natural gas, NGLs and condensate prices, we periodically enter into futures, forward purchases and sales, options or swap transactions in order to hedge anticipated purchases and sales of natural gas, NGLs and condensate. Interest-rate swaps are used from time to time to manage interest-rate risk. Under certain conditions, these derivative instruments are designated as a hedge of exposure to changes in fair values or cash flows. All relationships between hedging instruments and hedged items are formally documented, as well as risk-management objectives and strategies for undertaking various hedge transactions, and methods for assessing and testing correlation and hedge ineffectiveness. The forecasted transaction that has been designated as the hedged item in a cash flow hedge relationship is specifically identified. The effectiveness of hedging relationships are assessed quarterly by performing an effectiveness analysis on the fair value and cash flow hedging relationships to determine whether the hedge relationships are highly effective on a retrospective and prospective basis. Normal purchases and normal sales transactions that are expected to result in physical delivery and, through election, are exempt from derivative accounting treatment are also documented.

The realized revenues and purchase costs of derivative instruments not considered held for trading purposes and derivatives that qualify as normal purchases or normal sales that are expected to result in physical delivery are reported on a gross basis.

Cash flows from futures, forwards and swaps that are accounted for as hedges are included in the same category as the cash flows from the related hedged items in our Consolidated Statements of Cash Flows.

Cash Flow Hedges - At June 30, 2016, our Consolidated Balance Sheet reflected a net loss of $159.2 million in accumulated other comprehensive loss. The portion of accumulated other comprehensive loss attributable to commodity derivative financial instruments is an unrealized loss of $8.8 million, net of tax, which will be realized within the next 18 months as the forecasted transactions affect earnings. If commodity prices remain at current levels, we will realize approximately $5.8 million in net losses over the next 12 months and approximately $3.0 million in net losses thereafter. The amount deferred in accumulated other comprehensive loss attributable to settled interest-rate swaps is a loss of $47.0 million, net of tax, which will be recognized over the life of the long-term, fixed-rate debt, including losses of $6.3 million, net of tax, that will be reclassified into earnings during the next 12 months as the hedged items affect earnings. The remaining amounts in accumulated other comprehensive loss are attributable primarily to forward-starting interest-rate swaps with future settlement dates, which will be amortized to interest expense over the life of long-term, fixed-rate debt upon issuance of the debt.

Ineffectiveness related to our cash flow hedges for the three and six months ended June 30, 2016 and 2015, was not material. In the event that it becomes probable that a forecasted transaction will not occur, we would discontinue cash flow hedge treatment, which would affect earnings. For the three and six months ended June 30, 2016 and 2015, there were no gains or losses due to the discontinuance of cash flow hedge treatment.

Credit Risk - We monitor the creditworthiness of our counterparties and compliance with policies and limits established by our Risk Oversight and Strategy Committee. We maintain credit policies with regard to our counterparties that we believe minimize overall credit risk. These policies include an evaluation of potential counterparties’ financial condition (including credit ratings, bond yields and credit default swap rates), collateral requirements under certain circumstances and the use of standardized master-netting agreements that allow us to net the positive and negative exposures associated with a single counterparty. We have counterparties whose credit is not rated, and for those customers, we use internally developed credit ratings.

From time to time, ONEOK Partners may enter into financial derivative instruments that contain provisions that require it to maintain an investment-grade credit rating from S&P and/or Moody’s. If ONEOK Partners’ credit ratings on its senior unsecured long-term debt were to decline below investment grade, the counterparties to the derivative instruments could request collateralization on derivative instruments in net liability positions. There were no financial derivative instruments with contingent features related to credit risk at June 30, 2016.

The counterparties to our derivative contracts consist primarily of major energy companies, financial institutions and commercial and industrial end users. This concentration of counterparties may affect our overall exposure to credit risk, either positively or negatively, in that the counterparties may be affected similarly by changes in economic, regulatory or other conditions. Based on our policies, exposures, credit and other reserves, we do not anticipate a material adverse effect on our financial position or results of operations as a result of counterparty nonperformance.

At June 30, 2016, the net credit exposure from our derivative assets is primarily with investment-grade companies in the financial services sector.

D.
SHORT-TERM BORROWINGS

ONEOK Credit Agreement - In January 2016, we extended the term of the ONEOK Credit Agreement by one year to January 2020. The ONEOK Credit Agreement is a $300 million revolving credit facility and contains certain financial, operational and legal covenants. Among other things, these covenants include maintaining a ratio of indebtedness to Consolidated EBITDA (EBITDA, as defined in our ONEOK Credit Agreement) of no more than 4.0 to 1. Upon breach of certain covenants by us in

Table of Contents

the ONEOK Credit Agreement, amounts outstanding under the ONEOK Credit Agreement, if any, may become due and payable immediately. At June 30, 2016, ONEOK’s ratio of indebtedness to Consolidated EBITDA was 2.2 to 1, and ONEOK was in compliance with all covenants under the ONEOK Credit Agreement.

The ONEOK Credit Agreement includes a $50 million sublimit for the issuance of standby letters of credit and a $50 million sublimit for swingline loans. Under the terms of the ONEOK Credit Agreement, ONEOK may request an increase in the size of the facility to an aggregate of $500 million from $300 million by either commitments from new lenders or increased commitments from existing lenders. The ONEOK Credit Agreement contains provisions for an applicable margin rate and an annual facility fee, both of which adjust with changes in our credit rating. Based on our current credit rating, borrowings, if any, will accrue interest at LIBOR plus 145 basis points, and the annual facility fee is 30 basis points.

At June 30, 2016, ONEOK had $1.1 million in letters of credit issued and no borrowings under the ONEOK Credit Agreement.

ONEOK Partners Credit Agreement - In January 2016, ONEOK Partners extended the term of the ONEOK Partners Credit Agreement by one year to January 2020. The ONEOK Partners Credit Agreement is a $2.4 billion revolving credit facility and includes a $100 million sublimit for the issuance of standby letters of credit and a $150 million swingline sublimit. The ONEOK Partners Credit Agreement is available for general partnership purposes.

ONEOK Partners had $14 million of letters of credit issued, no borrowings outstanding and approximately $1.8 billion capacity available at June 30, 2016, under the ONEOK Partners Credit Agreement.

The ONEOK Partners Credit Agreement contains provisions for an applicable margin rate and an annual facility fee, both of which adjust with changes in its credit rating. Under the terms of the ONEOK Partners Credit Agreement, based on ONEOK Partners’ current credit ratings, borrowings, if any, will accrue at LIBOR plus 117.5 basis points, and the annual facility fee is 20 basis points. The ONEOK Partners Credit Agreement is guaranteed fully and unconditionally by the Intermediate Partnership. Borrowings under the ONEOK Partners Credit Agreement are nonrecourse to ONEOK.

The ONEOK Partners Credit Agreement contains certain financial, operational and legal covenants. Among other things, these covenants include maintaining a ratio of indebtedness to adjusted EBITDA (EBITDA, as defined in the ONEOK Partners Credit Agreement, adjusted for all noncash charges and increased for projected EBITDA from certain lender-approved capital expansion projects) of no more than 5.0 to 1. If ONEOK Partners consummates one or more acquisitions in which the aggregate purchase price is $25 million or more, the allowable ratio of indebtedness to adjusted EBITDA will increase to 5.5 to 1 for the quarter in which the acquisition was completed and the two following quarters. If ONEOK Partners were to breach certain covenants in the ONEOK Partners Credit Agreement, amounts outstanding under the ONEOK Partners Credit Agreement, if any, may become due and payable immediately. At June 30, 2016, ONEOK Partners’ ratio of indebtedness to adjusted EBITDA was 4.2 to 1, and it was in compliance with all covenants under the ONEOK Partners Credit Agreement.

Neither ONEOK nor ONEOK Partners guarantees the debt or other similar commitments of unaffiliated parties. ONEOK does not guarantee the debt, commercial paper or other similar commitments of ONEOK Partners, and ONEOK Partners does not guarantee the debt or other similar commitments of ONEOK.

ONEOK Partners Commercial Paper Program - At June 30, 2016, ONEOK Partners had $576 million of commercial paper outstanding under its $2.4 billion commercial paper program with weighted-average interest rates of 1.17 percent. Amounts outstanding under ONEOK Partners’ commercial paper program reduce the borrowing capacity under the ONEOK Partners Credit Agreement.

ONEOK Debt Issuance - In August 2015, we completed an underwritten public offering of $500 million, 7.5 percent senior notes due 2023. The net proceeds, after deducting underwriting discounts, commissions and other expenses, were approximately $487.1 million. We used the proceeds together with cash on hand to purchase $650 million of additional common units from ONEOK Partners.

ONEOK Partners Debt Issuances and Maturities - In January 2016, ONEOK Partners entered into the $1.0 billion senior unsecured delayed-draw Term Loan Agreement with a syndicate of banks. The Term Loan Agreement matures in January 2019 and bears interest at LIBOR plus a margin that is based on the credit ratings assigned to ONEOK Partners’ senior, unsecured, long-term indebtedness. Based on ONEOK Partners’ current applicable credit rating, borrowings on the Term Loan Agreement accrue at LIBOR plus 130 basis points. At June 30, 2016 the interest rate was 1.74 percent. The Term Loan Agreement contains an option, which may be exercised up to two times, to extend the term of the loan, in each case, for an additional one-year term, subject to approval of the banks. The Term Loan Agreement allows prepayment of all or any portion outstanding without penalty or premium and contains substantially the same covenants as the ONEOK Partners Credit Agreement. During the first quarter 2016, ONEOK Partners drew the full $1.0 billion available under the agreement and used the proceeds to repay its $650 million, 3.25 percent senior notes, to repay amounts outstanding under its commercial paper program and for general partnership purposes. At June 30, 2016, ONEOK Partners’ $450 million, 6.15 percent senior notes due October 1, 2016, are reflected in current maturities of long-term debt in our Consolidated Balance Sheet.

Table of Contents

In March 2015, ONEOK Partners completed an underwritten public offering of $800 million of senior notes, consisting of $300 million, 3.8 percent senior notes due 2020, and $500 million, 4.9 percent senior notes due 2025. The net proceeds, after deducting underwriting discounts, commissions and other expenses, were approximately $792.3 million. ONEOK Partners used the proceeds to repay amounts outstanding under its commercial paper program and for general partnership purposes.

ONEOK Partners incurred expenses in transactions with unconsolidated affiliates of $34.7 million and $25.9 million for the three months ended June 30, 2016 and 2015, respectively, and $68.3 million and $45.8 million for the six months ended June 30, 2016 and 2015, respectively, primarily related to Overland Pass Pipeline Company and Northern Border Pipeline. Accounts payable to ONEOK Partners’ equity-method investees at June 30, 2016, and December 31, 2015, were $12.2 million and $8.0 million, respectively.

Northern Border Pipeline - The Northern Border Pipeline partnership agreement provides that distributions to Northern Border Pipeline’s partners are to be made on a pro rata basis according to each partner’s percentage interest. The Northern Border Pipeline Management Committee determines the amount and timing of such distributions. Any changes to, or suspension of, the cash distribution policy of Northern Border Pipeline requires the unanimous approval of the Northern Border Pipeline Management Committee. Cash distributions are equal to 100 percent of distributable cash flow as determined from Northern Border Pipeline’s financial statements based upon EBITDA, less interest expense and maintenance capital expenditures. Loans or other advances from Northern Border Pipeline to its partners or affiliates are prohibited under its credit agreement.

Table of Contents

Overland Pass Pipeline Company - The Overland Pass Pipeline Company limited liability company agreement provides that distributions to Overland Pass Pipeline Company’s members are to be made on a pro rata basis according to each member’s percentage interest. The Overland Pass Pipeline Company Management Committee determines the amount and timing of such distributions. Any changes to, or suspension of, the cash distributions from Overland Pass Pipeline Company requires the unanimous approval of the Overland Pass Pipeline Company Management Committee. Cash distributions are equal to 100 percent of available cash as defined in the limited liability company agreement.

Roadrunner Gas Transmission - In March 2015, ONEOK Partners entered into a 50-50 joint venture with a subsidiary of Fermaca Infrastructure B.V. (Fermaca), a Mexico City-based natural gas infrastructure company, to construct a pipeline to transport natural gas from the Permian Basin in West Texas to the Mexican border near El Paso, Texas. During the six months ended June 30, 2016, ONEOK Partners made contributions of approximately $20 million to Roadrunner, and expects to contribute approximately $45 million to Roadrunner during the remainder of 2016.

The Roadrunner limited liability company agreement provides that distributions to members are made on a pro rata basis according to each member’s ownership interest. The Roadrunner Management Committee determines the amount and timing of such distributions. Any changes to, or suspension of, the cash distributions from Roadrunner requires approval of the Roadrunner Management Committee. Voting rights for the Roadrunner Management Committee are allocated on a pro rata basis according to each member’s ownership interest. Cash distributions are equal to 100 percent of available cash, as defined in the limited liability company agreement.

ONEOK PARTNERS

Ownership Interest in ONEOK Partners - Our ownership interest in ONEOK Partners is shown in the table below at June 30, 2016:
General partner interest
2.0
%
Limited partner interest (a)
39.2
%
Total ownership interest
41.2
%
(a) - Represents 41.3 million common units and approximately 73.0 million Class B units, which are convertible, at our option, into common units.

Consolidation - We determined ONEOK Partners is a VIE due to the limited partners’ lack of substantive voting rights under the Partnership Agreement. Substantive voting rights under a master limited partnership are either kick-out rights or participating rights, as defined by FASB Accounting Standards Codification 810-10, that can be exercised with a simple majority of the vote of the limited partners. Prior to the adoption of ASU 2015-02, ONEOK Partners was not considered a VIE and was consolidated by us under the presumption that a general partner consolidates its limited partnership. See Note A for more information on ASU 2015-02.

We have determined that we are the primary beneficiary of ONEOK Partners as we have the power, through our general partner interest, to direct the operations of ONEOK Partners that impact its economic performance and the right to receive the benefits of ONEOK Partners through our general partner and limited partner interests. These interests are significant due to our 41.2 percent ownership interest in ONEOK Partners, the largest ownership interest by an individual entity, and our incentive distribution rights.

As we are the primary beneficiary of ONEOK Partners, we consolidate ONEOK Partners in our consolidated financial statements; however, we are restricted from the assets and cash flows of ONEOK Partners except for the distributions we receive from ONEOK Partners. Distributions are declared quarterly by the board of ONEOK Partners’ general partner based on the terms of the Partnership Agreement. See Note N for more information on ONEOK Partners’ results.

ONEOK receives distributions from ONEOK Partners through its general partner and limited partner interests, but otherwise the assets of ONEOK Partners cannot be used to settle obligations of ONEOK. ONEOK does not guarantee the debt, commercial paper or other similar commitments of ONEOK Partners, and the obligations of ONEOK Partners may only be settled using the assets of ONEOK Partners. ONEOK Partners does not guarantee the debt or other similar commitments of ONEOK.

Equity Issuances - In August 2015, ONEOK Partners completed the sale to us in a private placement of 21.5 million common units at a price of $30.17 per unit. Additionally, ONEOK Partners completed a concurrent sale of approximately 3.3 million common units at a price of $30.17 per unit to funds managed by Kayne Anderson Capital Advisors in a registered direct offering, which were issued through ONEOK Partners’ existing “at-the-market” equity program. The combined offerings generated net proceeds of approximately $749 million. In conjunction with these issuances, ONEOK Partners GP contributed approximately $15.3 million in order to maintain our 2 percent general partner interest in ONEOK Partners. ONEOK Partners used the proceeds for general partnership purposes, including capital expenditures and repayment of commercial paper borrowings.

ONEOK Partners has an “at-the-market” equity program for the offer and sale from time to time of its common units, up to an aggregate amount of $650 million. The program allows ONEOK Partners to offer and sell its common units at prices it deems appropriate through a sales agent. Sales of common units are made by means of ordinary brokers’ transactions on the NYSE, in block transactions or as otherwise agreed to between ONEOK Partners and the sales agent. ONEOK Partners is under no obligation to offer and sell common units under the program. At June 30, 2016, ONEOK Partners had approximately $138 million of registered common units available for issuance through its “at-the-market” equity program.

During the three and six months ended June 30, 2016, no common units were sold through ONEOK Partners’ “at-the-market” equity program.

During the three months ended June 30, 2015, ONEOK Partners sold 5.5 million common units through its “at-the-market” equity program. The net proceeds, including ONEOK Partners GP’s contribution to maintain our 2 percent general partner interest in ONEOK Partners, were approximately $208.1 million, which were used for general partnership purposes, including repayment of commercial paper borrowings.

During the six months ended June 30, 2015, ONEOK Partners sold 7.2 million common units through its “at-the-market” equity program. The net proceeds, including ONEOK Partners GP’s contribution to maintain our 2 percent general partner interest in ONEOK Partners, were approximately $279.7 million, which were used for general partnership purposes, including repayment of commercial paper borrowings.

During the year ended December 31, 2015, ONEOK Partners sold 10.5 million common units through its “at-the-market” equity program, including the units sold to funds managed by Kayne Anderson Capital Advisors in the offering discussed above. The net proceeds, including ONEOK Partners GP’s contribution to maintain our 2 percent general partner interest in ONEOK Partners, were approximately $381.6 million, which were used for general partnership purposes, including repayment of commercial paper borrowings.

Table of Contents

We account for the difference between the carrying amount of our investment in ONEOK Partners and the underlying book value arising from issuance of common units by ONEOK Partners as an equity transaction. If ONEOK Partners issues common units at a price different than our carrying value per unit, we account for the premium or deficiency as an adjustment to paid-in capital.

Cash Distributions - We receive distributions from ONEOK Partners on the common and Class B units we own and the 2 percent general partner interest, which includes our incentive distribution rights. Under the Partnership Agreement, distributions are made to the partners with respect to each calendar quarter in an amount equal to 100 percent of available cash as defined in the Partnership Agreement. Available cash generally will be distributed 98 percent to limited partners and 2 percent to the general partner. The general partner’s percentage interest in quarterly distributions is increased after certain specified target levels are met during the quarter. Under the incentive distribution provisions, as set forth in the Partnership Agreement, the general partner receives:
15 percent of amounts distributed in excess of $0.3025 per unit;
25 percent of amounts distributed in excess of $0.3575 per unit; and
50 percent of amounts distributed in excess of $0.4675 per unit.

In July 2016, a cash distribution of $0.79 per unit ($3.16 per unit on an annualized basis) was declared for the second quarter 2016 and will be paid on August 14, 2016, to unitholders of record at the close of business on August 8, 2016.

Affiliate Transactions - We provide a variety of services to our affiliates, including cash management and financial services, employee benefits, legal and administrative services by our employees and management, insurance and office space leased in our headquarters building and other field locations. Where costs are incurred specifically on behalf of an affiliate, the costs are billed directly to the affiliate by us. In other situations, the costs may be allocated to the affiliates through a variety of methods, depending upon the nature of the expenses and the activities of the affiliates. For the three months ended June 30, 2016 and 2015, $100.8 million and $86.7 million, respectively, of ONEOK Partners’ operating expenses were incurred with us. For the

31

Table of Contents

six months ended June 30, 2016 and 2015, $189.9 million and $176.3 million, respectively, of ONEOK Partners’ operating expenses were incurred with us.

ONEOK Partners has an operating agreement with Roadrunner, that provides for reimbursement or payment to it for management services and certain operating costs. Charges to Roadrunner included in operating income in our Consolidated Statements of Income for the three and six months ended June 30, 2016 and 2015, were not material.

L.
COMMITMENTS AND CONTINGENCIES

Environmental Matters and Pipeline Safety - The operation of pipelines, plants and other facilities for the gathering, processing, transportation and storage of natural gas, NGLs, condensate and other products is subject to numerous and complex laws and regulations pertaining to health, safety and the environment. As an owner and/or operator of these facilities, ONEOK Partners must comply with United States laws and regulations at the federal, state and local levels that relate to air and water quality, hazardous and solid waste management and disposal, and other environmental matters. The cost of planning, designing, constructing and operating pipelines, plants and other facilities must incorporate compliance with environmental laws and regulations and safety standards. Failure to comply with these laws and regulations may trigger a variety of administrative, civil and potentially criminal enforcement measures, including citizen suits, which can include the assessment of monetary penalties, the imposition of remedial requirements and the issuance of injunctions or restrictions on operation. Management believes that, based on currently known information, compliance with these laws and regulations will not have a material adverse effect on our or ONEOK Partners’ results of operations, financial condition or cash flows.

Legal Proceedings - Gas Index Pricing Litigation - In May 2016, the United States District Court for the District of Nevada (“the Court”) entered an order granting summary judgment in favor of us and our affiliate ONEOK Energy Services Company, L.P. (“OESC”) in Reorganized FLI, Inc. previously reported in our Annual Report. The Court determined that the plaintiff’s claim is barred by a release obtained in a prior lawsuit against us and OESC. Upon entry of a final judgment, Reorganized FLI, Inc. may pursue an appeal of this determination to the Ninth Circuit Court of Appeals.

In March 2016, we reached an agreement in principle to settle the claims alleged against us and our affiliates, OESC and Kansas Gas Marketing Company, in the following putative class action lawsuits, previously reported in our Annual Report, that claimed damages resulting from alleged market manipulation or false reporting of prices to gas index publications by us and others: Learjet, Arandell, Heartland Regional Medical Center, and NewPage. The amount we expect to pay to settle these cases is not material to our results of operations, financial position or cash flows and is expected to be paid with cash on hand.

This agreement in principle to settle does not apply to the Sinclair case, previously reported in our Annual Report. We expect that future charges, if any, from the ultimate resolution of these matters will not be material to our results of operations, financial position or cash flows.

Other Legal Proceedings - We and ONEOK Partners are party to various other litigation matters and claims that have arisen in the normal course of our operations. While the results of these various other litigation matters and claims cannot be predicted with certainty, we believe the reasonably possible losses from such matters, individually and in the aggregate, are not material. Additionally, we believe the probable final outcome of such matters will not have a material adverse effect on our consolidated results of operations, financial position or cash flows.

DISCONTINUED OPERATIONS

In 2014, we completed the wind down of our former energy services business. We executed agreements to release a significant portion of our nonaffiliated natural gas transportation and storage contracts to third parties that resulted in noncash charges.

We expect future cash payments associated with released transportation and storage capacity contracts from the wind down of our former energy services business to total approximately $25 million, which consists of approximately $7 million to be paid in the remainder of 2016, $10 million in 2017, $4 million in 2018 and $4 million over the period 2019 through 2023.

Results of Operations of Discontinued Operations - The results of operations for our former energy services business have been reported as discontinued operations for all periods presented. Income (loss) from discontinued operations, net of tax, in the Consolidated Statements of Income for the three and six months ended June 30, 2016 and 2015, includes accretion expense, net of tax benefit, on the released contracts for our former energy services business.

Statement of Financial Position of Discontinued Operations - At June 30, 2016, and December 31, 2015, assets and liabilities of discontinued operations in our Consolidated Balance Sheets relate primarily to deferred tax assets and capacity release obligations associated with our former energy services business.

N.
SEGMENTS

Segment Descriptions - Our reportable business segments are based upon the following segments of ONEOK Partners:
the Natural Gas Gathering and Processing segment gathers, treats and processes natural gas;
the Natural Gas Liquids segment gathers, treats, fractionates and transports NGLs and stores, markets and distributes NGL products; and
the Natural Gas Pipelines segment operates regulated interstate and intrastate natural gas transmission pipelines and natural gas storage facilities.

Other and eliminations consist of the operating and leasing operations of our headquarters building and related parking facility and other amounts needed to reconcile our reportable segments to our consolidated financial statements.

Accounting Policies - The accounting policies of the segments are described in Note A of the Notes to Consolidated Financial Statements in our Annual Report. Our chief operating decision maker reviews the financial performance of each of the three segments of ONEOK Partners, as well as our financial performance, on a regular basis. Beginning in 2016, adjusted EBITDA by segment, a non-GAAP financial measure, is utilized in this evaluation. We believe this non-GAAP financial measure is useful to investors because it is used by many companies in our industry as a measurement of financial performance and is commonly employed by financial analysts and others to evaluate our financial performance and to compare our financial performance with the performance of other publicly traded partnerships within our industry. Adjusted EBITDA is defined as net income adjusted for interest expense, depreciation and amortization, noncash impairment charges, income taxes and AFUDC and other noncash items. Adjusted EBITDA should not be considered an alternative to net income, earnings per unit or any other measure of financial performance presented in accordance with GAAP. Additionally, this calculation may not be comparable with similarly titled measures of other companies. Prior period segment disclosures have been recast to reflect this change.

Customers - The primary customers of the Natural Gas Gathering and Processing segment are crude oil and natural gas producers, which include both large integrated and independent exploration and production companies. The Natural Gas Liquids segment’s customers are primarily NGL and natural gas gathering and processing companies; large integrated and independent crude oil and natural gas production companies; propane distributors; ethanol producers; and petrochemical, refining and NGL marketing companies. The Natural Gas Pipelines segment’s customers are primarily local natural gas distribution companies, electric-generation companies, large industrial companies, municipalities, irrigation customers and marketing companies.

For the three months ended June 30, 2016, ONEOK Partners had no single customer from which it received 10 percent or more of our consolidated revenues. For the three months ended June 30, 2015, and the six months ended June 30, 2016, and June 30, 2015, ONEOK Partners had one customer, BP p.l.c. or its affiliates, from which it received $224.6 million, $396.5 million and $409.5 million, respectively, in total revenues from all of its operating segments, or approximately 11 percent, 10 percent and 10 percent of our consolidated revenues, respectively.

ITEM 2.
MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our unaudited Consolidated Financial Statements and the Notes to Consolidated Financial Statements in this Quarterly Report, as well as our Annual Report.

RECENT DEVELOPMENTS

Please refer to the “Financial Results and Operating Information” and “Liquidity and Capital Resources” sections of Management’s Discussion and Analysis of Financial Condition and Results of Operations in this Quarterly Report for additional information.

Ownership of ONEOK Partners - ONEOK and its subsidiaries own all of the general partner interest and a portion of the limited partner interests, which, together, represent a 41.2 percent ownership interest at June 30, 2016, in ONEOK Partners (NYSE: OKS), one of the largest publicly traded master limited partnerships.

ONEOK Partners has a predominantly fee-based business in each of its three reportable segments and expects its consolidated earnings to be approximately 85 percent fee-based in 2016. Despite the lower crude oil, natural gas and NGL price environment and reduced capital spending by producers, we continue to expect demand for midstream nondiscretionary services and infrastructure development to be primarily driven by producers who need to connect production with end-use markets where current infrastructure is insufficient or nonexistent. We expect additional demand for ONEOK Partners’ services to support increased demand for NGL products from ethylene producers and NGL exporters and increased demand for natural gas from power plants previously fueled by coal and natural gas exports to Mexico.

We expect the Natural Gas Liquids segment’s earnings to be approximately 90 percent fee-based in 2016. ONEOK Partners connected seven third-party natural gas processing plants and its Lonesome Creek processing plant to the natural gas liquids system in 2015, three third-party natural gas processing plants in the first half of 2016 and expects to connect two additional third-party natural gas processing plants and its Bear Creek processing plant during the remainder of 2016, favorably impacting the Natural Gas Liquids segment’s fee-based volume growth. In this segment, ONEOK Partners is well-positioned to capture future increases in ethane transportation and fractionation volumes due to increased demand in the petrochemical industry from the completion of the ethylene production projects and NGL export activity without significant additional infrastructure needs or capital spending on ONEOK Partners’ system.

Ethane rejection levels by natural gas processors delivering to ONEOK Partners’ natural gas liquids gathering system decreased to approximately 150 MBbl/d during the second quarter 2016, compared with an average of more than 175 MBbl/d during the second half of 2015 and first quarter 2016, primarily in the Mid-Continent region. While the volume of ethane recovered increased during the second quarter 2016, a portion of the fees associated with those volumes gathered and fractionated was previously being earned under contracts with minimum volume obligations. We expect ethane rejection levels to continue to fluctuate for the remainder of 2016 as the market begins to balance ethane supply and demand and with changes in the price differentials between ethane and natural gas. We expect ethane rejection levels to decrease as ethylene producers and NGL exporters increase their capacity to consume and export additional ethane feedstock volumes. Ethane demand is expected to ramp up as new world-scale ethylene production projects, petrochemical plant modifications, plant expansions and export facilities near completion and begin coming on line in early 2017. We expect future ethane recoveries to have a favorable impact on our financial results.

In 2015, the Natural Gas Gathering and Processing segment restructured many POP with fee contracts associated with a significant amount of its gathered volumes to increase the fee-based component in the contracts. These restructured contracts and increased natural gas gathered and processed volumes favorably impacted results in the first half of 2016, and we expect to continue to receive the benefit of the improved earnings from these contracts and volumes throughout 2016. In the first half of 2016, the Natural Gas Gathering and Processing segment’s fee revenues averaged $0.72 per MMBtu, compared with an average of $0.37 per MMBtu in the first half of 2015. As a result of these restructured contracts, we expect the Natural Gas Gathering and Processing segment’s earnings to be more than 75 percent fee-based in 2016. To mitigate the impact of its remaining commodity price exposure, ONEOK Partners has hedged a significant portion of the Natural Gas Gathering and Processing segment’s commodity price risk for 2016 and 2017.

Although drilling activity continued to slow in the first half of 2016, many of ONEOK Partners’ customers continue to drill and complete new wells in the most productive areas of the Williston Basin. A significant portion of ONEOK Partners’ Williston Basin gathering and processing assets are located in these areas, which typically produce at higher initial production rates compared with other areas and have higher natural gas to oil ratios and have slower natural gas decline rates than crude oil.

Table of Contents

ONEOK Partners’ natural gas volumes gathered and processed and NGL volumes gathered and fractionated increased in the first half of 2016, compared with the first half of 2015, due primarily to the completion of six compressor stations during 2015 and the addition of the 200 MMcf/d Lonesome Creek plant in the fourth quarter 2015, which allowed ONEOK Partners to capture a significant portion of natural gas volumes previously being flared by producers in the Williston Basin. Additionally, we expect to benefit from production from new wells completed in the second half of 2016 and new wells on ONEOK Partners’ dedicated acreage in the Williston Basin that have been drilled previously but have not yet been completed.

We expect the Natural Gas Pipelines segment’s earnings to be approximately 96 percent fee-based in 2016. This segment continues to develop new projects to grow ONEOK Partners’ fee-based earnings, such as ONEOK Partners’ Roadrunner joint venture, which is a pipeline fully subscribed with 25-year firm, fee-based agreements. We expect additional demand for ONEOK Partners’ services to deliver natural gas to power plants previously fueled by coal and to support increased demand for natural gas exports to Mexico. Additionally, the Natural Gas Pipelines segment’s contracts are primarily with large creditworthy companies and include fixed fee or firm demand charge agreements that provide a minimum level of revenues regardless of commodity prices or volumetric throughput.

While commodity prices increased relative to the first quarter 2016, commodity prices in the first half of 2016 were relatively unchanged from year-end 2015 and lower compared with the first half of 2015. WTI crude oil prices averaged approximately $40.00 per barrel in the first half of 2016, compared with prices averaging approximately $50.00 per barrel in the first half of 2015. NYMEX natural gas prices averaged approximately $2.10 per MMBtu in the first half of 2016, compared with prices averaging approximately $2.80 per MMBtu in the first half of 2015. OPIS Conway propane prices averaged $0.40 per gallon in the first half of 2016, compared with prices averaging $0.45 per gallon in the first half of 2015.

We expect the lower commodity price environment to continue throughout 2016, impacting ONEOK Partners’ net realized prices for natural gas, NGLs and condensate, and our financial results. If the low commodity price environment persists for a prolonged period or prices decline further, volumes across ONEOK Partners’ assets may grow more slowly than in the past or decline.

Change in Presentation of Financial Results - Beginning in 2016, we present financial results using adjusted EBITDA by segment, a non-GAAP financial measure. We believe this non-GAAP financial measure is useful to investors because it aids in comparing our financial performance with that of other companies with similar operations and is commonly employed to evaluate our financial performance. We have added adjusted EBITDA to the presentation of consolidated financial results and the financial results of each reporting segment. See additional discussion in the “Adjusted EBITDA” section.

ONEOK Partners’ Growth Projects - Crude oil and natural gas producers continue to drill for crude oil and NGL-rich natural gas in many regions where ONEOK Partners operates, including in the Bakken Shale and Three Forks formations in the Williston Basin; in the Cana-Woodford Shale, Woodford Shale, Springer Shale, STACK and SCOOP areas in the Mid-Continent region; and in the Permian Basin. ONEOK Partners’ current projects are expected to expand its natural gas gathering and processing and natural gas liquids gathering infrastructure in the Williston Basin to capture natural gas from new wells and additional natural gas currently being flared by producers, and to supply ethane produced by its Stateline de-ethanizers to customers exporting to Canada. In the Natural Gas Pipelines segment, through the Roadrunner joint venture, the Roadrunner pipeline transports natural gas from the Permian Basin in West Texas to the Mexican border near El Paso, Texas, and is fully subscribed with 25-year firm, fee-based agreements. Phase I of the Roadrunner pipeline was completed in March 2016. The Roadrunner pipeline connects with ONEOK Partners’ existing natural gas pipeline and storage infrastructure in Texas and, together with the WesTex intrastate natural gas transmission pipeline expansion project, creates a platform for future opportunities to deliver natural gas supply to Mexico. Phase II of the Roadrunner pipeline, which is currently under construction and expected to be complete in the fourth quarter 2016, will provide additional delivery capacity to these markets in Mexico. The execution of these capital investments aligns with ONEOK Partners’ strategy to generate consistent growth and sustainable earnings through long-term fee-based projects. ONEOK Partners’ contractual commitments from crude oil and natural gas producers, natural gas processors and electric generators are expected to provide incremental cash flows and long-term fee-based earnings.

In 2016, ONEOK Partners expects lower capital spending, compared with 2015, due to the completion of projects and spending reductions to align with customer needs. If the current commodity price environment persists for a prolonged period, it may further impact the timing or demand for additional infrastructure projects or growth opportunities in the future.

See additional discussion of ONEOK Partners’ other growth projects in the “Financial Results and Operating Information” section in the Natural Gas Gathering and Processing, Natural Gas Liquids and Natural Gas Pipelines segments.

Due to the nature of ONEOK Partners’ contracts, changes in commodity prices and volumes affect both commodity sales and cost of sales and fuel in our Consolidated Statements of Income and therefore the impact is largely offset between the two line items.

Operating income increased for the three and six months ended June 30, 2016, compared with the same periods in 2015, due primarily to higher natural gas gathered and NGL volumes from ONEOK Partners’ completed capital projects in the Natural Gas Gathering and Processing and Natural Gas Liquids segments and new plant connections and decreased ethane rejection in the Natural Gas Liquids segment, and higher fees resulting from contract restructuring in the Natural Gas Gathering and Processing segment. These increases were offset partially by lower net realized NGL and natural gas prices in the Natural Gas Gathering and Processing segment, higher depreciation expense due to projects completed in 2015, higher costs associated with the impact of the non-cash mark-to-market of a share-based deferred compensation plan and higher employee-related costs associated with incentive and medical benefit plans.

Equity in net earnings from investments increased for the three and six months ended June 30, 2016, compared with the same periods in 2015, due primarily to higher volumes delivered to Overland Pass Pipeline from ONEOK Partners’ Bakken NGL Pipeline.

Interest expense increased for the three months ended June 30, 2016, compared with the same period in 2015, primarily as a result of higher interest costs incurred associated with ONEOK Partners’ borrowing under the Term Loan Agreement during the first quarter 2016, higher short-term borrowing rates and lower capitalized interest due to lower spending on capital-growth projects and higher interest costs incurred associated with our $500 million debt issuance in August 2015. Interest expense increased for the six months ended June 30, 2016, compared with the same period in 2015, primarily as a result of the items discussed above and higher interest costs incurred associated with ONEOK Partners’ issuance of $800 million of senior notes in March 2015.

Adjusted EBITDA increased for the three and six months ended June 30, 2016, compared with the same periods in 2015, due primarily to higher natural gas gathered and NGL volumes from ONEOK Partners’ completed capital-growth projects in the Natural Gas Gathering and Processing and Natural Gas Liquids segments and new plant connections and decreased ethane rejection in the Natural Gas Liquids segment, and higher fees resulting from contract restructuring in the Natural Gas Gathering and Processing segment. These increases were offset partially by lower net realized NGL and natural gas prices in the Natural Gas Gathering and Processing segment.

Capital expenditures decreased for the three and six months ended June 30, 2016, compared with the same periods in 2015, due to projects placed in service in 2015, spending reductions to align with customer needs and lower well connect activities in the Natural Gas Gathering and Processing segment due to a reduction in drilling and completion activity.

Additional information regarding our financial results and operating information is provided in the following discussion for each of the segments.

Natural Gas Gathering and Processing

Overview - The Natural Gas Gathering and Processing segment provides nondiscretionary services to contracted producers in North Dakota, Montana, Wyoming, Kansas and Oklahoma. It provides exploration and production companies with gathering and processing services that allow them to move their raw (unprocessed) natural gas to market. Raw natural gas is gathered, compressed and transported through pipelines to its processing facilities. In order for the raw natural gas to be accepted by the downstream market, it must have contaminants, such as water, nitrogen and carbon dioxide, removed as well as NGLs separated for further processing. Processed natural gas, usually referred to as residue natural gas, is then recompressed and delivered to natural gas pipelines and end users. The separated NGLs are in a mixed, unfractionated form and are sold and delivered through natural gas liquids pipelines to fractionation facilities for further separation.

This segment gathers and processes natural gas in the Williston Basin, which is located in portions of North Dakota and Montana, including the oil-producing, NGL-rich Bakken Shale and Three Forks formation, and is its most active region with continued volume growth and additional gathering and processing infrastructure needs. The Mid-Continent region is located in Western Oklahoma, which includes the NGL-rich Cana-Woodford Shale, STACK, SCOOP, Woodford Shale, Springer Shale and the Mississippian Lime formation; and Southwest Kansas, which includes the Hugoton Basin, Central Kansas Uplift Basin and the Mississippian Lime formation. The Powder River Basin is primarily located in Wyoming, which includes the NGL-rich Frontier, Turner, Sussex and Niobrara Shales where ONEOK Partners’ Sage Creek system provides gathering and processing services to customers in the southeast portion of Wyoming.

Revenues for this segment are derived primarily from POP contracts with fee-based components and fee-only contracts. Under a POP contract with fee-based components, ONEOK Partners charges fees for gathering, treating, compressing and processing the producer’s natural gas, and retains a percentage of the proceeds from the sale of residue natural gas, condensate and/or NGLs. Over time as these contracts are renewed or restructured, ONEOK Partners has generally increased the fee components and reduced the percent of proceeds retained from the sale of the commodities. As a result, ONEOK Partners’ mix of commodity and fee-based earnings continues to change as volumes naturally decline on older contracts where it retains a higher percent of proceeds and volumes increase on contracts with higher fee components. Additionally, under certain POP with fee contracts the fee revenues may increase or decrease if production volumes, delivery pressures or commodity prices change relative to specified thresholds. With a fee-only contract, ONEOK Partners is paid a fee for the services it provides, based on volumes gathered, processed, treated and/or compressed.

ONEOK Partners has restructured many of its contracts to significantly increase its fees, and as a result of these restructured contracts, we expect the Natural Gas Gathering and Processing segment’s earnings to be more than 75 percent fee-based in 2016. These restructured contracts and increased natural gas gathered and processed volumes favorably impacted ONEOK Partners’ results for the three and six months ended June 30, 2016, and we expect to continue to receive the benefit of improved earnings from these contracts. ONEOK Partners’ NGLs, natural gas and crude oil commodity price sensitivity in this segment has continued to decrease in 2016 as a result of these restructured contracts. Additionally, ONEOK Partners uses commodity

40

Table of Contents

derivative instruments and physical-forward contracts to reduce its near-term sensitivity to fluctuations in the natural gas, crude oil and NGL commodity prices under POP with fee contracts. ONEOK Partners will continue to seek opportunities to increase its fee-based earnings and reduce its commodity price exposure.

We expect ONEOK Partners’ natural gas gathered and processed volumes in the Williston Basin to grow in 2016, compared with 2015, despite expected reductions in producer drilling activity, due to the following:
the opportunity to capture additional natural gas currently being flared by producers through natural gas compression and processing capacity placed in service in late 2015 and projects that are expected to be completed in 2016;
the connection of wells that have been drilled but not yet completed;
producers focusing their drilling in the most productive areas in which ONEOK Partners has significant gathering and processing assets, which typically produce at higher initial production rates compared with other areas and have higher natural gas to oil ratios and have slower natural gas decline rates than crude oil;
the use by producers of more efficient drilling rigs; and
continued improvements in production results by producers due to enhanced completion techniques.

In the Mid-Continent region, ONEOK Partners’ producer customers continue to focus their drilling and completion activities in the core Cana-Woodford, STACK and SCOOP areas of Oklahoma, and recent wells have shown strong results; however, several large multi-well pads previously scheduled to be completed in late 2015 and early 2016 have been delayed until late 2016 or early 2017. As a result, ONEOK Partners’ 2016 volumes in the Mid-Continent could decline.

Growth Projects - The Natural Gas Gathering and Processing segment is investing in growth projects in NGL-rich areas in the Williston Basin, STACK, SCOOP, Cana-Woodford Shale, Woodford Shale and Springer Shale areas that ONEOK Partners expects will enable it to meet the needs of crude oil and natural gas producers in those areas. Nearly all of the new natural gas production in these areas is from horizontally drilled wells in nonconventional resource areas. These wells tend to produce volumes at higher initial production rates resulting generally in higher initial decline rates than conventional vertical wells; however, the decline rates flatten out over time. These wells are expected to have long productive lives.

As a result of reductions in crude oil and natural gas drilling by producers due to the decline in crude oil, natural gas and NGL prices and the expectation of slower supply growth or declines, in 2015 ONEOK Partners suspended capital expenditures for certain natural gas processing plants and field infrastructure. ONEOK Partners could resume its suspended capital-growth projects when market conditions improve and its customers’ needs change. If the current commodity price environment

41

persists for a prolonged period, it may further impact the timing or demand for these projects and additional infrastructure projects or growth opportunities in the future.

For a discussion of ONEOK Partners’ capital expenditure financing, see “Capital Expenditures” in the “Liquidity and Capital Resources” section.

Selected Financial Results - The Natural Gas Gathering and Processing segment’s financial results for the three and six months ended June 30, 2016, reflect the benefits from the completed projects in the table above. The lower commodity price environment continues to impact ONEOK Partners’ 2016 financial results but the impact has been mitigated partially by restructured contracts, which became effective primarily in the fourth quarter 2015 and first quarter 2016. Additionally, with current market conditions, crude oil and natural gas producers are focusing their drilling activities in the most productive areas that are most economical to develop and have higher production volumes, which offsets partially the reduction in drilling activity.

Adjusted EBITDA increased $32.2 million for the three months ended June 30, 2016, compared with the same period in 2015, primarily as a result of the following:
an increase of $36.6 million due primarily to restructured contracts resulting in higher average fee rates and a lower percentage of proceeds retained from the sale of commodities under the POP with fee contracts; and
an increase of $33.5 million due primarily to natural gas volume growth in the Williston Basin, offset partially by volume declines in the Mid-Continent region; offset partially by
a decrease of $28.6 million due primarily to lower net realized NGL and natural gas prices;
an increase of $5.8 million in operating costs due primarily to higher employee-related costs associated with incentive and medical benefit plans and ONEOK Partners’ completed capital projects; and
a decrease of $1.8 million due primarily to decreased ethane rejection to maintain downstream NGL product specifications.

Adjusted EBITDA increased $71.7 million for the six months ended June 30, 2016, compared with the same period in 2015, primarily as a result of the following:
an increase of $78.5 million due primarily to restructured contracts resulting in higher average fee rates and a lower percentage of proceeds retained from the sale of commodities under the POP with fee contracts; and
an increase of $64.7 million due primarily to natural gas volume growth in the Williston Basin, offset partially by volume declines in the Mid-Continent region; offset partially by
a decrease of $58.5 million due primarily to lower net realized NGL and natural gas prices;

an increase of $6.1 million in operating costs due primarily to higher employee-related costs associated with incentive and medical benefit plans and ONEOK Partners’ completed capital projects; and
a decrease of $4.0 million due primarily to decreased ethane rejection to maintain downstream NGL product specifications.

Capital expenditures decreased for the three and six months ended June 30, 2016, compared with the same periods in 2015, due to projects placed in service in 2015, spending reductions to align with customer needs and lower well connect activities due to a reduction in drilling and completion activity.

Natural gas gathered, natural gas processed and NGL sales increased during the three months ended June 30, 2016, compared with the same period in 2015, due to the completion of growth projects in the Williston Basin, offset partially by planned facility maintenance and weather events in the Williston Basin and natural gas volume declines in the Mid-Continent region.

Natural gas gathered, natural gas processed, NGL sales and residue natural gas sales increased during the six months ended June 30, 2016, compared with the same period in 2015, due to the completion of growth projects in the Williston Basin, offset partially by planned facility maintenance and weather events in the Williston Basin and natural gas volume declines in the Mid-Continent region.

The quantity and composition of NGLs and natural gas have varied as new plants were placed in service and to ensure natural gas and natural gas liquids pipeline specifications were met. Beginning in June 2015, ONEOK Partners reduced the level of ethane rejection in the Rocky Mountain region to address downstream NGL product specifications.

Natural Gas Liquids

Overview - The Natural Gas Liquids segment owns and operates facilities that gather, fractionate, treat and distribute NGLs and store NGL products, primarily in Oklahoma, Kansas, Texas, New Mexico and the Rocky Mountain region where it provides nondiscretionary services to producers of NGLs and delivers those products to the two primary market centers, one in the Mid-Continent in Conway, Kansas, and the other in the Gulf Coast in Mont Belvieu, Texas. It owns or has an ownership interest in FERC-regulated natural gas liquids gathering and distribution pipelines in Oklahoma, Kansas, Texas, New Mexico, Montana, North Dakota, Wyoming and Colorado, and terminal and storage facilities in Missouri, Nebraska, Iowa and Illinois. ONEOK Partners also owns FERC-regulated natural gas liquids distribution and refined petroleum products pipelines in Kansas, Missouri, Nebraska, Iowa, Illinois and Indiana that connect its Mid-Continent assets with Midwest markets, including Chicago, Illinois. The majority of the pipeline-connected natural gas processing plants in Oklahoma, Kansas and the Texas Panhandle, which extract unfractionated NGLs from unprocessed natural gas, are connected to its gathering systems. ONEOK Partners owns and operates truck- and rail-loading and -unloading facilities connected to its natural gas liquids fractionation, storage and pipeline assets.

Most natural gas produced at the wellhead contains a mixture of NGL components, such as ethane, propane, iso-butane, normal butane and natural gasoline. The NGLs that are separated from the natural gas stream at natural gas processing plants remain in a mixed, unfractionated form until they are gathered, primarily by pipeline, and delivered to fractionators where the NGLs are separated into NGL products. These NGL products are then stored or distributed to customers, such as petrochemical manufacturers, heating fuel users, ethanol producers, refineries, exporters and propane distributors.

Earnings for the Natural Gas Liquids segment are derived primarily from nondiscretionary fee-based services that ONEOK Partners provides to its customers and from the physical optimization of its assets. This segment also purchases NGLs and condensate from third parties, as well as from the Natural Gas Gathering and Processing segment. The segment’s fee-based services have increased due primarily to new supply connections, expansion of existing connections and the completion of capital projects. The segment’s business activities are categorized as exchange and storage services, transportation services, and optimization and marketing, which are defined as follows:
ONEOK Partners’ exchange and storage services utilize its assets to gather, fractionate and/or treat, and transport unfractionated NGLs, thereby converting them into marketable NGL products that are stored and shipped to a market center or customer-designated location. Many of these exchange volumes are under contracts with minimum volume commitments that provide a minimum level of revenues regardless of volumetric throughput. Although ONEOK Partners’ exchange services activities are primarily fee-based, it also captures certain product price differentials as volumes are fractionated. ONEOK Partners’ storage activities consist primarily of fee-based NGL storage services at its Mid-Continent and Gulf Coast storage facilities.
ONEOK Partners’ transportation services transport, primarily by pipeline, NGL products and refined petroleum products, primarily under FERC-regulated tariffs. Tariffs specify the maximum rates ONEOK Partners charges its customers and the general terms and conditions for NGL transportation service on its pipelines.
ONEOK Partners’ optimization and marketing activities utilize its assets, contract portfolio and market knowledge to capture location, product and seasonal price differentials. It primarily transports NGL products between Conway, Kansas, and Mont Belvieu, Texas, to capture the location price differentials between the two market centers. ONEOK Partners’ marketing activities also include utilizing its natural gas liquids storage facilities to capture seasonal price differentials. A growing portion of ONEOK Partners’ marketing activities serves truck and rail markets. ONEOK Partners’ isomerization activities capture the price differential when normal butane is converted into the more valuable iso-butane at its isomerization unit in Conway, Kansas.

Excess NGL supply continues to result in narrow NGL location price differentials between the Mid-Continent and Gulf Coast market centers. We expect these narrow price differentials to persist between the Conway, Kansas, and Mont Belvieu, Texas, market centers, as a result of NGL production increases from various NGL-rich shale areas throughout the country, until demand for NGLs increases from petrochemicals and exporters, which we anticipate to begin in 2017.

Supply growth has resulted in available ethane supplies that are greater than the petrochemical industry’s current demand. As a result, low or unprofitable price differentials between ethane and natural gas have resulted in ethane rejection at most of ONEOK Partners’ and its customers’ natural gas processing plants connected to its natural gas liquids gathering system in the Mid-Continent and Rocky Mountain regions during 2015 and into 2016, which reduced natural gas liquids volumes gathered, fractionated, transported and sold across ONEOK Partners’ assets. Through ethane rejection, natural gas processors leave much of the ethane component in the natural gas stream sold at the tailgate of natural gas processing plants. Ethane rejection levels by natural gas processors delivering to ONEOK Partners’ natural gas liquids gathering system decreased to approximately 150 MBbl/d during the second quarter 2016, compared with an average of more than 175 MBbl/d during the second half of 2015

and first quarter 2016, primarily in the Mid-Continent region. While the volume of ethane recovered increased during the second quarter 2016, a portion of the fees associated with those volumes gathered and fractionated was previously being earned under contracts with minimum volume obligations. We expect ethane rejection levels to continue to fluctuate for the remainder of 2016 as the market begins to balance ethane supply and demand and with changes in the price differentials between ethane and natural gas. We expect ethane rejection levels to decrease as ethylene producers and NGL exporters increase their capacity to consume and export additional ethane feedstock volumes. Ethane demand is expected to ramp up as new world-scale ethylene production projects, petrochemical plant modifications, plant expansions and export facilities near completion and begin coming on line in early 2017.

Despite the ethane rejection across ONEOK Partners’ system, beginning in June 2015, the Natural Gas Gathering and Processing segment reduced its level of ethane rejection in the Williston Basin to alleviate downstream NGL product specification issues, which offsets partially the financial impact of ethane rejection. We expect this decreased ethane rejection to continue throughout 2016. In addition, the Natural Gas Liquids segment’s integrated assets enable ONEOK Partners to mitigate partially the impact of ethane rejection through minimum volume commitments, contract modifications that vary fees for ethane and other NGL products, and ONEOK Partners’ ability to utilize the transportation capacity made available due to ethane rejection to capture additional NGL location price differentials, when they exist, in its optimization activities.

Growth Projects - ONEOK Partners’ growth strategy in the Natural Gas Liquids segment is focused around the crude oil and NGL-rich natural gas drilling activity in shale and other nonconventional resource areas from the Rocky Mountain region through the Mid-Continent region into Texas and New Mexico. Crude oil, natural gas and NGL production from this activity; higher petrochemical industry demand for NGL products; and increased exports have resulted in ONEOK Partners making additional capital investments to expand its infrastructure to bring these commodities from supply basins to market. Expansion of the petrochemical industry in the United States is expected to increase ethane demand significantly beginning in 2017, and international demand for NGLs, particularly ethane and propane, also is increasing.

In April 2015, ONEOK Partners completed the NGL Pipeline and Hutchinson Fractionator infrastructure project for approximately $120 million, excluding AFUDC.

As a result of reductions in crude oil and natural gas drilling activities and the expectation of continued slower supply growth or declines due to the lower crude oil, natural gas and NGL prices, ONEOK Partners has suspended capital expenditures for certain natural gas liquids infrastructure projects related to planned natural gas processing plants. ONEOK Partners could resume its suspended capital-growth projects when market conditions improve and its customers’ needs change. If the current commodity price environment persists for a prolonged period, it may further impact the timing or demand for these projects and additional infrastructure projects or growth opportunities in the future.

Adjusted EBITDA increased $32.0 million for the three months ended June 30, 2016, compared with the same period in 2015, primarily as a result of the following:
an increase of $27.7 million in exchange services, which includes:
a $22.4 million increase due to increased volumes from recently connected natural gas processing plants in the Williston Basin and Mid-Continent region, offset partially by lower short-term contracted volumes in the Gulf Coast region; and
a $21.7 million increase from decreased ethane rejection in the Williston Basin and Mid-Continent region, which increased NGL volumes gathered and fractionated; offset partially by
a $15.4 million decrease in revenues from minimum volume obligations as earnings were realized through the increased volumes and decreased ethane rejection described above;
an increase of $8.1 million in optimization and marketing activities, which resulted from a $5.4 million increase due primarily to wider marketing product price differentials and a $2.7 million increase due primarily to higher optimization volumes;
an increase of $4.2 million in equity in net earnings from investments due primarily to higher volumes delivered to Overland Pass Pipeline from ONEOK Partners’ Bakken NGL Pipeline;
an increase of $2.6 million related to higher isomerization volumes, resulting from wider NGL product price differentials between normal butane and iso-butane; offset partially by
an increase of $6.4 million in operating costs due primarily to higher employee-related costs associated with incentive and medical benefit plans; and
a decrease of $5.6 million due to the impact of operational measurement losses in 2016 and operational measurement gains in 2015.

Adjusted EBITDA increased $109.6 million for the six months ended June 30, 2016, compared with the same period in 2015, primarily as a result of the following:
an increase of $88.7 million in exchange services, which includes:
a $64.0 million increase due to increased volumes from recently connected natural gas processing plants in the Williston Basin and Mid-Continent region, offset partially by lower short-term contracted volumes in the Gulf Coast region;
a $38.7 million increase from decreased ethane rejection in the Williston Basin and Mid-Continent region, which increased NGL volumes gathered and fractionated; and
a $5.7 million increase due to higher fee rates; offset partially by
a $18.7 million decrease in revenues from minimum volume obligations as earnings were realized through the increased volumes and decreased ethane rejection described above;
an increase of $10.6 million in equity in net earnings from investments due primarily to higher volumes delivered to Overland Pass Pipeline from ONEOK Partners’ Bakken NGL Pipeline;
an increase of $4.2 million in optimization and marketing activities, which resulted from a $7.1 million increase due

primarily to higher optimization volumes, offset partially by a $2.9 million decrease due primarily to narrower marketing product price differentials;
an increase of $3.0 million in higher storage activities; and
a decrease of $2.7 million in operating costs due to lower operating costs resulting from ongoing cost reduction efforts and lower rates charged by service providers, offset partially by higher employee-related costs associated with incentive and medical benefit plans.

Capital expenditures decreased for the three and six months ended June 30, 2016, compared with the same periods in 2015, due primarily to spending reductions to align with customer needs.

Natural Gas Pipelines

Overview - The Natural Gas Pipelines segment provides transportation and storage services to end users through its wholly owned assets, its 50 percent ownership in Northern Border Pipeline and its 50 percent ownership in Roadrunner. Phase I of the Roadrunner pipeline was completed in March 2016, and Phase II is currently under construction and is expected to be complete in the fourth quarter 2016.

Interstate Pipelines - ONEOK Partners’ interstate pipelines are regulated by the FERC and are located in North Dakota, Minnesota, Wisconsin, Illinois, Indiana, Kentucky, Tennessee, Oklahoma, Texas and New Mexico. ONEOK Partners’ interstate pipeline companies include:
Midwestern Gas Transmission, which is a bidirectional system that interconnects with Tennessee Gas Transmission Company’s pipeline near Portland, Tennessee, and with several interstate pipelines at the Chicago Hub near Joliet, Illinois, that have access to both the Utica Shale and Marcellus Shale;
Viking Gas Transmission, which is a bidirectional system that interconnects with a TransCanada Corporation pipeline near Emerson, Manitoba, and ANR Pipeline Company near Marshfield, Wisconsin;
Guardian Pipeline, which interconnects with several pipelines at the Chicago Hub near Joliet, Illinois, and with local natural gas distribution companies in Wisconsin; and

47

Table of Contents

OkTex Pipeline, which has interconnections with several pipelines in Oklahoma, Texas and New Mexico.

Intrastate Pipelines - ONEOK Partners’ intrastate natural gas pipeline assets in Oklahoma transport natural gas through the state and have access to the major natural gas producing formations, including the Cana-Woodford Shale, Woodford Shale, Springer Shale, Granite Wash, STACK, SCOOP and Mississippian Lime. ONEOK Partners’ intrastate natural gas pipeline assets in Oklahoma serve end-use markets, such as local distribution companies and power generation companies. In Texas, ONEOK Partners’ intrastate natural gas pipelines are connected to the major natural gas producing formations in the Texas Panhandle, including the Granite Wash formation and the Delaware and Cline producing formations in the Permian Basin. These pipelines are capable of transporting natural gas throughout the western portion of Texas, including the Waha Hub where other pipelines may be accessed for transportation to western markets, exports to Mexico, the Houston Ship Channel market to the east and the Mid-Continent market to the north. ONEOK Partners’ intrastate natural gas pipeline assets also have access to the natural gas producing formations in south central Kansas.

Through its Roadrunner joint venture, Roadrunner transports natural gas from the Permian Basin in West Texas to the Mexican border near El Paso, Texas, and is fully subscribed with 25-year firm, fee-based agreements. The Roadrunner pipeline connects with ONEOK Partners’ existing natural gas pipeline and storage infrastructure in Texas and, together with its WesTex intrastate natural gas pipeline expansion project, creates a platform for future opportunities to deliver natural gas supply to Mexico. Phase II of the Roadrunner pipeline, which is currently under construction and is expected to be complete in the fourth quarter 2016, will provide additional delivery capacity to these markets in Mexico.

Transportation Rates - Transportation contracts for ONEOK Partners’ regulated natural gas services are based upon rates stated in the respective tariffs. The tariffs provide both the general terms and conditions for the facilities and the maximum allowed rates customers can be charged by type of service, which may be discounted to meet competition if necessary. The rates are established at FERC or the appropriate state jurisdictional agencies. The earnings are primarily fee-based from the following types of services:
Firm service - Customers reserve a fixed quantity of pipeline capacity for a specified period of time, which obligates the customer to pay for services regardless of usage. Under this type of contract, the customer pays a fixed fee and incremental fees, known as commodity charges, which are based on the actual volumes of natural gas they transport or store. In addition, ONEOK Partners may retain a percentage of fuel in-kind based on the volumes of natural gas transported. Under the firm service contract, the customer generally is guaranteed access to the capacity they reserve.
Interruptible service - Under interruptible service transportation agreements, the customer may utilize available capacity after firm service requests are satisfied. The customer is not guaranteed use of ONEOK Partners’ pipelines unless excess capacity is available. Customers typically are assessed fees, such as a commodity charge, and ONEOK Partners may retain a specified volume of natural gas in-kind based on their actual usage.

Storage - ONEOK Partners owns natural gas storage facilities located in Texas and Oklahoma that are connected to its intrastate natural gas pipelines. It also has underground natural gas storage facilities in Kansas. In Texas and Kansas, natural gas storage operations may be regulated by the state in which the facility operates and by the FERC for certain types of services. In Oklahoma, natural gas storage operations are not subject to rate regulation by the state and have market-based rate authority from the FERC for certain types of services.

Storage Rates - The earnings are primarily fee-based from the following types of services:
Firm service - Customers reserve a specific quantity of storage capacity, including injection and withdrawal rights, and generally pay fixed fees based on the quantity of capacity reserved plus an injection and withdrawal fee. Firm storage contracts typically have terms longer than one year.
Park-and-loan service - An interruptible service offered to customers providing the ability to park (inject) or loan (withdraw) natural gas into or out of storage, typically for monthly or seasonal terms. Customers reserve the right to park or loan natural gas based on a specified quantity, including injection and withdrawal rights when capacity is available.

Roadrunner - In 2015, Roadrunner entered into a $230 million senior secured credit facility for the construction and operation of the pipeline. The senior secured credit facility expires seven years after the Roadrunner Phase II in-service date, which is expected to be completed in the fourth quarter 2016. In addition, Roadrunner executed interest-rate swaps to hedge the variability of its interest payments during the term of the credit facility. Roadrunner’s credit facility is nonrecourse to ONEOK and ONEOK Partners, and neither ONEOK nor ONEOK Partners guarantees Roadrunner’s debts or obligations under the credit facility. ONEOK Partners contributed approximately $20 million to Roadrunner in the six months ended June 30, 2016, and approximately $30 million in the year ended December 31, 2015. ONEOK Partners expects to contribute an additional $45 million to Roadrunner during the remainder of 2016.

ONEOK Partners’ natural gas pipelines primarily serve end users, such as natural gas distribution and electric-generation companies, that require natural gas to operate their businesses regardless of location price differentials. The development of shale and other resource areas has continued to increase available natural gas supply resulting in narrower location and seasonal price differentials. As additional supply is developed, ONEOK Partners expects crude oil and natural gas producers to demand incremental services in the future to transport their production to market. The abundance of natural gas supply and new regulations on emissions from coal-fired electric-generation plants may also increase the demand for ONEOK Partners’ services from electric-generation companies as they convert to a natural gas fuel source. Overall, ONEOK Partners expects its fee-based earnings in this segment to remain relatively stable. Growth will continue in the Permian Basin as ONEOK Partners completes construction of its Roadrunner joint venture and its WesTex pipeline expansion.

Northern Border Pipeline, in which ONEOK Partners has a 50 percent ownership interest, has contracted substantially all of its long-haul transportation capacity through the third quarter 2017. Roadrunner, in which ONEOK Partners has a 50 percent ownership interest, has contracted all of its capacity for both Phase I and Phase II through the first quarter 2041.

Adjusted EBITDA

Adjusted EBITDA is a non-GAAP measure of our financial performance. Adjusted EBITDA is defined as net income adjusted for interest expense, depreciation and amortization, noncash impairment charges, income taxes and AFUDC and other noncash items. We believe this non-GAAP financial measure is useful to investors because it is used by many companies in our industry as a measurement of financial performance and is commonly employed by financial analysts and others to evaluate our financial performance and to compare our financial performance with the performance of other publicly traded companies within our industry. Adjusted EBITDA should not be considered an alternative to net income, earnings per unit or any other measure of financial performance presented in accordance with GAAP. Additionally, this calculation may not be comparable with similarly titled measures of other companies.

CONTINGENCIES

Gas Index Pricing Litigation - In May 2016, the Court entered an order granting summary judgment in favor of us and our affiliate ONEOK Energy Services Company, L.P., (“OESC”) in Reorganized FLI, Inc. (formerly J.P. Morgan Trust Company) v. ONEOK, Inc., et al. (filed in the District Court of Wyandotte County, Kansas, in October 2005, transferred to MDL 166 in the United States District Court for the District of Nevada). The Court determined that the plaintiff’s claim is barred by a release obtained in a prior lawsuit against us and OESC. Upon entry of a final judgment, Reorganized FLI, Inc. may pursue an appeal of this determination to the Ninth Circuit Court of Appeals.

In March 2016, we reached an agreement in principle to settle the claims alleged against us and our affiliates, OESC and Kansas Gas Marketing Company, in the following putative class action lawsuits that claimed damages resulting from alleged market manipulation or false reporting of prices to gas index publications by us and others: Learjet, Inc., et al. v. ONEOK, Inc., et al. (filed in the District Court of Wyandotte, Kansas, in November 2005, transferred to MDL-1566 in the United States District Court for the District of Nevada); Arandell Corporation, et al. v. Xcel Energy, Inc., et al. (filed in the Circuit Court for Dane County, Wisconsin, in December 2006, transferred to MDL-1566 in the United States District Court for the District of Nevada); Heartland Regional Medical Center, et al. v. ONEOK, Inc., et al. (filed in the Circuit Court of Buchanan County, Missouri, in March 2007, transferred to MDL-1566 in the United States District Court for the District of Nevada); and NewPage Wisconsin System v. CMS Energy Resource Management Company, et al. (filed in the Circuit Court for Wood County, Wisconsin, in March 2009, transferred to MDL-1566 in the United States District Court for the District of Nevada and now consolidated with the Arandell case). The amount we expect to pay to settle these cases is not material to our results of operations, financial position or cash flows and is expected to be paid with cash on hand.

This agreement in principle to settle does not apply to Sinclair Oil Corporation v. ONEOK Energy Services Corporation, L.P., et al. (filed in the United States District Court for the District of Wyoming in September 2005, transferred to MDL-1566 in the United States District Court for the District of Nevada). We expect that future charges, if any, from the ultimate resolution of this matter will not be material to our results of operations, financial position or cash flows.

Other Legal Proceedings - We and ONEOK Partners are party to various other litigation matters and claims that have arisen in the normal course of our operations. While the results of these various other litigation matters and claims cannot be predicted with certainty, we believe the reasonably possible losses from such matters, individually and in the aggregate, are not material. Additionally, we believe the probable final outcome of such matters will not have a material adverse effect on our consolidated results of operations, financial position or cash flows.

LIQUIDITY AND CAPITAL RESOURCES

General - We fund operating expenses, debt service and dividends to shareholders primarily from cash distributions received from ONEOK Partners.

Neither ONEOK nor ONEOK Partners guarantees the debt or other similar commitments of unaffiliated parties. ONEOK does not guarantee the debt or other similar commitments of ONEOK Partners, and ONEOK Partners does not guarantee the debt or other similar commitments of ONEOK.

ONEOK - ONEOK’s primary source of cash inflows are distributions to us from our general partner and limited partner interests in ONEOK Partners. The cash distributions that we expect to receive from ONEOK Partners are expected to provide sufficient resources to fund our operations, debt service and quarterly cash dividends. At June 30, 2016, we had $177.1 million of cash on hand. Our next long-term debt maturity is in 2022.

We expect future cash expenditures associated with the released transportation and storage capacity from the wind down of our former energy services business to be approximately $25 million, with approximately $7 million to be paid in the remainder of 2016, $10 million in 2017, $4 million in 2018 and $4 million over the period 2019 through 2023.

ONEOK Partners - ONEOK Partners relies primarily on operating cash flows, commercial paper, bank credit facilities, debt issuances and the issuance of common units for its liquidity and capital resources requirements. As of June 30, 2016, ONEOK Partners had $3.7 million of cash on hand and available capacity under its Partnership Credit Agreement of $1.8 billion. In addition, in the first quarter 2016, ONEOK Partners drew the full $1.0 billion available under its Term Loan Agreement that matures in January 2019.

ONEOK Partners funds its operating expenses, debt service and cash distributions to its limited partners and general partner primarily with operating cash flows. To the extent operating cash flows are not sufficient to fund its cash distributions, ONEOK Partners may utilize short- and long-term debt and issuances of equity, as necessary. Capital expenditures are funded by operating cash flows, short- and long-term debt and issuances of equity. ONEOK Partners’ ability to continue to access capital markets for debt and equity financing under reasonable terms depends on its financial condition, credit ratings and market conditions. The significant decline in commodity prices has increased the cost of debt and equity financing for ONEOK Partners and others in the industry. While lower commodity prices and industry uncertainty may result in increased financing costs, ONEOK Partners expects to utilize its commercial paper program, Partnership Credit Agreement, Term Loan Agreement and cash from operations to fund its announced capital-growth expenditures, refinance its senior notes maturities and meet its working capital needs through 2016 and well into 2017. However, ONEOK Partners may access the capital markets to issue debt or equity securities prior to that time as it considers prudent to provide liquidity for new capital projects, to maintain investment-grade credit ratings or for other partnership purposes.

Cash Management - We and ONEOK Partners each use similar centralized cash management programs that concentrate the cash assets of our operating subsidiaries in joint accounts for the purposes of providing financial flexibility and lowering the cost of borrowing, transaction costs and bank fees. Both centralized cash management programs provide that funds in excess of the daily needs of the operating subsidiaries are concentrated, consolidated or otherwise made available for use by other entities within the respective consolidated groups. ONEOK Partners’ operating subsidiaries participate to the extent they are permitted pursuant to FERC regulations or their operating agreements. Under these cash management programs, depending on whether a participating subsidiary has short-term cash surpluses or cash requirements, we and ONEOK Partners provide cash to our respective subsidiaries or the subsidiaries provide cash to us.

Short-term Liquidity - ONEOK’s sources of short-term liquidity are quarterly distributions from ONEOK Partners, cash on hand of $177.1 million as of June 30, 2016, and access to our $300 million ONEOK Credit Agreement. At June 30, 2016, ONEOK had no short-term debt outstanding.

ONEOK Partners’ principal sources of short-term liquidity consist of cash generated from operating activities, distributions received from its equity-method investments and proceeds from its commercial paper program, the ONEOK Partners Credit Agreement and its “at-the-market” equity program.

ONEOK Partners had working capital (defined as current assets less current liabilities) deficits of $1 billion and $697 million as of June 30, 2016, and December 31, 2015, respectively. Although working capital is influenced by several factors, including, among other things, (i) the timing of (a) scheduled debt payments, (b) the collection and payment of accounts receivable and payable, and (c) equity and debt issuances, and (ii) the volume and cost of inventory and commodity imbalances, ONEOK Partners’ working capital deficit at June 30, 2016, was driven primarily by its capital-growth projects and

Table of Contents

current maturities of its long-term debt. ONEOK Partners’ working capital deficit at December 31, 2015, was driven primarily by its capital-growth projects. ONEOK Partners may have working capital deficits in future periods as it continues to finance its capital-growth projects, often initially with short-term borrowings. We do not expect ONEOK Partners’ working capital deficit to have an adverse impact to our or ONEOK Partners’ cash flows or operations. The consolidated working capital balance is impacted primarily by ONEOK Partners’ working capital balance.

ONEOK Credit Agreement - In January 2016, we extended the term of our ONEOK Credit Agreement by one year to January 2020. At June 30, 2016, ONEOK had $1.1 million of letters of credit issued under the ONEOK Credit Agreement and approximately $177.1 million of cash and cash equivalents. We had $298.9 million of credit available at June 30, 2016, under the ONEOK Credit Agreement.

The ONEOK Credit Agreement is a $300 million revolving credit facility and contains certain financial, operational and legal covenants. Among other things, these covenants include maintaining a ratio of indebtedness to Consolidated EBITDA (EBITDA, as defined in the ONEOK Credit Agreement) of no more than 4.0 to 1. Upon breach of certain covenants by us in the ONEOK Credit Agreement, amounts outstanding under the ONEOK Credit Agreement, if any, may become due and payable immediately. At June 30, 2016, our ratio of indebtedness to Consolidated EBITDA, was 2.2 to 1, and we were in compliance with all covenants under the ONEOK Credit Agreement.

The ONEOK Credit Agreement also includes a $50 million sublimit for the issuance of standby letters of credit and a $50 million sublimit for swingline loans. Under the terms of the ONEOK Credit Agreement, we may request an increase in the size of the facility to an aggregate of $500 million from $300 million by either commitments from new lenders or increased commitments from existing lenders. The ONEOK Credit Agreement contains provisions for an applicable margin rate and an annual facility fee, both of which adjust with changes in our credit rating. Based on our current credit rating, borrowings, if any, will accrue interest at LIBOR plus 145 basis points, and the annual facility fee is 30 basis points.

ONEOK Partners Credit Agreement - At June 30, 2016, ONEOK Partners had $576 million of commercial paper outstanding, $14 million of letters of credit issued and no borrowings outstanding under the ONEOK Partners Credit Agreement. At June 30, 2016, ONEOK Partners had approximately $3.7 million of cash and cash equivalents and approximately $1.8 billion of credit available under the ONEOK Partners Credit Agreement.

In January 2016, ONEOK Partners extended the term of the ONEOK Partners Credit Agreement by one year to January 2020. The ONEOK Partners Credit Agreement is a $2.4 billion revolving credit facility and includes a $100 million sublimit for the issuance of standby letters of credit and a $150 million swingline sublimit. The ONEOK Partners Credit Agreement is available for general partnership purposes. Amounts outstanding under ONEOK Partners’ commercial paper program reduce the borrowing capacity under the ONEOK Partners Credit Agreement.

The ONEOK Partners Credit Agreement contains provisions for an applicable margin rate and an annual facility fee, both of which adjust with changes in ONEOK Partners’ credit rating. Under the terms of the ONEOK Partners Credit Agreement, based on ONEOK Partners’ current credit rating, borrowings, if any, will accrue at LIBOR plus 117.5 basis points, and the annual facility fee is 20 basis points. The ONEOK Partners Credit Agreement is guaranteed fully and unconditionally by the Intermediate Partnership.

The ONEOK Partners Credit Agreement contains certain financial, operational and legal covenants. Among other things, these covenants include maintaining a ratio of indebtedness to adjusted EBITDA (EBITDA, as defined in the ONEOK Partners Credit Agreement, adjusted for all noncash charges and increased for projected EBITDA from certain lender-approved capital expansion projects) of no more than 5.0 to 1. If ONEOK Partners consummates one or more acquisitions in which the aggregate purchase price is $25 million or more, the allowable ratio of indebtedness to adjusted EBITDA will increase to 5.5 to 1 for the quarter in which the acquisition was completed and the two following quarters. If ONEOK Partners were to breach certain covenants in the ONEOK Partners Credit Agreement, amounts outstanding under the ONEOK Partners Credit Agreement, if any, may become due and payable immediately. At June 30, 2016, ONEOK Partners’ ratio of indebtedness to adjusted EBITDA was 4.2 to 1, and it was in compliance with all covenants under the ONEOK Partners Credit Agreement. At June 30, 2016, ONEOK Partners could have issued $1.5 billion of short- and long-term debt to meet its liquidity needs under the most restrictive provisions contained in its various borrowing agreements.

Borrowings under the ONEOK Partners Credit Agreement, the Term Loan Agreement and ONEOK Partners’ senior notes are nonrecourse to ONEOK, and ONEOK does not guarantee ONEOK Partners’ debt, commercial paper or other similar commitments.

Long-term Financing - In addition to our principal sources of short-term liquidity discussed above, we expect ONEOK Partners to fund its longer-term financing requirements by issuing common units or long-term notes. Other options to obtain financing include, but are not limited to, loans from financial institutions, issuance of convertible debt securities, asset securitization and the sale and lease-back of facilities.

ONEOK Partners’ ability to obtain financing is subject to changes in the debt and equity markets, and there is no assurance it will be able or willing to access the public or private markets in the future. ONEOK Partners may choose to meet its cash requirements by utilizing some combination of cash flows from operations, borrowing under its commercial paper program or the ONEOK Partners Credit Agreement, altering the timing of controllable expenditures, restricting future acquisitions and capital projects, selling assets or pursuing other debt or equity financing alternatives. Some of these alternatives could result in higher costs or negatively affect its respective credit ratings, among other factors. Based on ONEOK Partners’ investment-grade credit ratings, general financial condition, and expectations regarding its future earnings and projected cash flows, we expect ONEOK Partners will be able to meet its cash requirements and maintain investment-grade credit ratings.

ONEOK Debt Issuance - In August 2015, we completed an underwritten public offering of $500 million, 7.5 percent senior notes due 2023. The net proceeds, after deducting underwriting discounts, commissions and other expenses, were approximately $487.1 million. We used the proceeds together with cash on hand to purchase $650 million of additional common units from ONEOK Partners.

ONEOK Partners Debt Issuances and Maturities - In January 2016, ONEOK Partners entered into the $1.0 billion senior unsecured delayed-draw Term Loan Agreement with a syndicate of banks. During the first quarter 2016, ONEOK Partners drew the full $1.0 billion available under the agreement and used the proceeds to repay its $650 million, 3.25 percent senior notes, which matured in February 2016, to repay amounts outstanding under its commercial paper program and for general partnership purposes. The Term Loan Agreement matures in January 2019 and bears interest at LIBOR plus a margin that is based on the credit ratings assigned to ONEOK Partners’ senior, unsecured, long-term indebtedness. Based on ONEOK Partners’ current applicable credit rating, borrowings on the Term Loan Agreement will accrue at LIBOR plus 130 basis points. The Term Loan Agreement contains an option, which may be exercised up to two times, to extend the term of the loan, in each case, for an additional one-year term subject to approval of the banks. The Term Loan Agreement allows prepayment of all or any portion outstanding, without penalty or premium, and contains substantially the same covenants as those contained in the ONEOK Partners Credit Agreement.

In March 2015, ONEOK Partners completed an underwritten public offering of $800 million of senior notes, consisting of $300 million, 3.8 percent senior notes due 2020 and $500 million, 4.9 percent senior notes due 2025. The net proceeds, after deducting underwriting discounts, commissions and offering expenses, were approximately $792.3 million. ONEOK Partners used the proceeds to repay amounts outstanding under its commercial paper program and for general partnership purposes.

ONEOK Partners expects to repay its $450 million, 6.15 percent senior notes due October 1, 2016, with a combination of cash on hand and short-term borrowings.

ONEOK Partners Equity Issuances - In August 2015, ONEOK Partners completed the sale to us in a private placement of 21.5 million common units at a price of $30.17 per unit. Additionally, ONEOK Partners completed a concurrent sale of approximately 3.3 million common units at a price of $30.17 per unit to funds managed by Kayne Anderson Capital Advisors in a registered direct offering, which were issued through ONEOK Partners’ existing “at-the-market” equity program. The combined offerings generated net proceeds of approximately $749 million. In conjunction with these issuances, ONEOK Partners GP contributed approximately $15.3 million in order to maintain our 2 percent general partner interest in ONEOK Partners. ONEOK Partners used the proceeds for general partnership purposes, including capital expenditures and repayment of commercial paper borrowings.

ONEOK Partners has an “at-the-market” equity program for the offer and sale from time to time of its common units, up to an aggregate amount of $650 million. The program allows ONEOK Partners to offer and sell its common units at prices it deems appropriate through a sales agent. Sales of common units are made by means of ordinary brokers’ transactions on the NYSE, in block transactions or as otherwise agreed to between ONEOK Partners and the sales agent. ONEOK Partners is under no obligation to offer and sell common units under the program. At June 30, 2016, ONEOK Partners had approximately $138 million of registered common units available for issuance through its “at-the-market” equity program.

During the three and six months ended June 30, 2016, no common units were sold through ONEOK Partners’ “at-the-market” equity program.

Table of Contents

During the three months ended June 30, 2015, ONEOK Partners sold 5.5 million common units through its “at-the-market” equity program. The net proceeds, including ONEOK Partners GP’s contribution to maintain our 2 percent general partner interest in ONEOK Partners, were approximately $208.1 million, which were used for general partnership purposes, including repayment of commercial paper borrowings.

During the six months ended June 30, 2015, ONEOK Partners sold 7.2 million common units through its “at-the-market” equity program. The net proceeds, including ONEOK Partners GP’s contribution to maintain our 2 percent general partner interest in ONEOK Partners, were approximately $279.7 million, which were used for general partnership purposes, including repayment of commercial paper borrowings.

During the year ended December 31, 2015, ONEOK Partners sold 10.5 million common units through its “at-the-market” equity program, including the units sold to funds managed by Kayne Anderson Capital Advisors in the offering discussed above. The net proceeds, including ONEOK Partners GP’s contribution to maintain our 2 percent general partner interest in ONEOK Partners, were approximately $381.6 million, which were used for general partnership purposes, including repayment of commercial paper borrowings.

Interest-rate Swaps - As of June 30, 2016, ONEOK Partners had interest-rate swaps with notional amounts totaling $1.0 billion to hedge the variability of its LIBOR-based interest payments. In June 2016, ONEOK Partners entered into forward-starting interest-rate swaps with notional amounts totaling $750 million to hedge the variability of interest payments on a portion of its forecasted debt issuances that may result from changes in the benchmark interest rate before the debt is issued. At June 30, 2016, and December 31, 2015, ONEOK Partners had forward-starting interest-rate swaps with notional amounts totaling $1.2 billion and $400 million, respectively, to hedge the variability of interest payments on a portion of its forecasted debt issuances. All of ONEOK Partners’ interest-rate swaps are designated as cash flow hedges.

Capital Expenditures - ONEOK Partners’ capital expenditures are financed typically through operating cash flows, short- and long-term debt and the issuance of equity. ONEOK Partners’ capital expenditures were $332.3 million and $628.4 million for the six months ended June 30, 2016 and 2015, respectively.

ONEOK Partners’ commercial paper program is rated Prime-2 by Moody’s and A-2 by S&P. ONEOK Partners’ credit ratings, which are investment-grade, may be affected by a material change in its financial ratios or a material event affecting its business and industry. The most common criteria for assessment of ONEOK Partners’ credit ratings are the debt-to-EBITDA ratio, interest coverage, business risk profile and liquidity.

Declines in the energy commodity price environment and its impact on ONEOK Partners’ results of operations and cash flows could cause the credit rating agencies to downgrade its credit ratings. If ONEOK Partners’ credit ratings were downgraded, the cost to borrow funds under its commercial paper program and the ONEOK Partners Credit Agreement would increase, and ONEOK Partners could potentially lose access to the commercial paper market. In the event that ONEOK Partners is unable to borrow funds under its commercial paper program and there has not been a material adverse change in its business, ONEOK Partners would continue to have access to the ONEOK Partners Credit Agreement, which expires in January 2020. An adverse credit rating change alone is not a default under the ONEOK Credit Agreement or the ONEOK Partners Credit Agreement. A

downgrade in ONEOK Partners’ credit ratings would likely result in a downgrade to ONEOK’s credit ratings. However, we would not expect a downgrade to our credit ratings to have a material impact on our results of operations.

In the normal course of business, ONEOK Partners’ counterparties provide secured and unsecured credit. In the event of a downgrade in ONEOK Partners’ credit ratings or a significant change in ONEOK Partners’ counterparties’ evaluation of its creditworthiness, ONEOK Partners could be required to provide additional collateral in the form of cash, letters of credit or other negotiable instruments as a condition of continuing to conduct business with such counterparties. ONEOK Partners may be required to fund margin requirements with its counterparties with cash, letters of credit or other negotiable instruments.

ONEOK Partners Cash Distributions - ONEOK Partners distributes 100 percent of its available cash, as defined in its Partnership Agreement, that generally consists of all cash receipts less adjustments for cash disbursements and net change to reserves, to its general and limited partners. Distributions are allocated to the general partner and limited partners according to their partnership percentages of 2 percent and 98 percent, respectively. The effect of any incremental allocations for incentive distributions to the general partner is calculated after the allocation to the general partner’s partnership interest and before the allocation to the limited partners.

For the three and six months ended June 30, 2016, and 2015, ONEOK Partners’ cash distributions exceeded its cash flow from operations. As a result, ONEOK Partners utilized cash from operations, its commercial paper program and distributions received from its equity-method investments to fund cash distributions, short-term liquidity needs and capital projects. ONEOK Partners expects increases in cash flows from operations in the remainder of 2016, compared with the first half of 2016, due primarily to the completion of its growth projects and new plant connections that ONEOK Partners expects will provide increasing volumes in the Natural Gas Gathering and Processing and Natural Gas Liquids segments. See discussion under “Short-term Liquidity” and “Long-term Financing” for more information.

Energy Commodity Prices - Although ONEOK Partners is subject to commodity price volatility, its commodity price exposure has been reduced due primarily to contract restructuring in the Natural Gas Gathering and Processing segment. ONEOK Partners has also hedged a significant portion of the Natural Gas Gathering and Processing segment’s commodity price risk for 2016 and 2017. Significant fluctuations in commodity prices will affect its overall liquidity due to the impact commodity price changes have on its cash flows from operating activities, including the impact on working capital for NGLs and natural gas held in storage, margin requirements and certain energy-related receivables. While lower commodity prices and industry uncertainty may result in increased financing costs, we believe ONEOK Partners has secured sufficient access to the financial resources and liquidity necessary to meet its requirements for working capital, debt service payments and capital expenditures through 2016 and well into 2017. We believe that its available credit and cash and cash equivalents are adequate to meet liquidity requirements associated with commodity price volatility. See Note C of the Notes to Consolidated Financial Statements and the discussion under “Commodity Price Risk” in Part I, Item 3, Quantitative and Qualitative Disclosures About Market Risk, in this Quarterly Report for information on ONEOK Partners’ hedging activities.

Pension and Postretirement Benefit Plans - Information about our pension and postretirement benefits plans, including anticipated contributions, is included under Note N of the Notes to Consolidated Financial Statements in our Annual Report. See Note I of the Notes to Consolidated Financial Statements in this Quarterly Report for additional information.

CASH FLOW ANALYSIS

We use the indirect method to prepare our Consolidated Statements of Cash Flows. Under this method, we reconcile net income to cash flows provided by operating activities by adjusting net income for those items that affect net income but do not result in actual cash receipts or payments during the period and for operating cash items that do not impact net income. These reconciling items include depreciation and amortization, allowance for equity funds used during construction, gain or loss on sale of assets, deferred income taxes, equity in net earnings from investments, distributions received from unconsolidated affiliates, share-based compensation expense, other amounts and changes in our assets and liabilities not classified as investing or financing activities.

Operating Cash Flows - Operating cash flows are affected by earnings from our business activities. Changes in commodity prices and demand for our services or products, whether because of general economic conditions, changes in supply, changes in demand for the end products that are made with our products or increased competition from other service providers, could affect our earnings and operating cash flows.

Cash flows from operating activities, before changes in operating assets and liabilities, were $686.4 million for the six months ended June 30, 2016, compared with $518.4 million for the same period in 2015. The increase is due primarily to higher natural gas gathered and NGL volumes from ONEOK Partners’ completed capital-growth projects in the Natural Gas Gathering and Processing and Natural Gas Liquids segments and higher fees resulting from contract restructuring in the Natural Gas Gathering and Processing segment, offset partially by lower commodity prices, as discussed in “Financial Results and Operating Information.”

The changes in operating assets and liabilities decreased operating cash flows by $154.8 million for the six months ended June 30, 2016, compared with a decrease of $184.5 million for the same period in 2015. This change is due primarily to the change in accounts receivable, accounts payable, and other accruals and deferrals resulting from the timing of receipt of cash from customers and payments to vendors, suppliers, and other third parties; and the change in natural gas and NGLs in storage, which vary from period to period and vary with changes in commodity prices.

Investing Cash Flows - Cash used in investing activities decreased to $298.5 million for the six months ended June 30, 2016, compared with $655.8 million for the same period in 2015, due primarily to ONEOK Partners’ lower capital spending, compared with 2015, as a result of spending reductions to align with customer needs and projects placed in service in 2015, offset partially by proceeds received from ONEOK Partners’ sale of assets and higher distributions from unconsolidated affiliates.

Financing Cash Flows - Cash used in financing activities was $149.6 million for the six months ended June 30, 2016, compared with cash provided by financing activities of $374.9 million for the six months ended June 30, 2015. This change is due primarily to repayment of ONEOK Partners’ $650 million, 3.25 percent senior notes, which matured February 1, 2016. ONEOK Partners received long-term debt proceeds in the six months ended June 30, 2016, related to its $1.0 billion Term Loan Agreement, compared with proceeds from debt and equity issuances in the same period in 2015, related to its $800 million senior notes offering and approximately $280 million from equity issuances through its “at-the-market” equity program.

REGULATORY, ENVIRONMENTAL AND SAFETY MATTERS

Environmental Matters - ONEOK Partners is subject to multiple environmental, historical preservation and wildlife preservation laws and/or regulations that affect many aspects of its present and future operations. Regulated activities include, but are not limited to, those involving air emissions, storm water and wastewater discharges, handling and disposal of solid and hazardous wastes, wetlands preservation, hazardous materials transportation, and pipeline and facility construction. These laws and regulations require ONEOK Partners to obtain and/or comply with a wide variety of environmental clearances, registrations, licenses, permits and other approvals. Failure to comply with these laws, regulations, licenses and permits may expose ONEOK Partners to fines, penalties and/or interruptions in its operations that could be material to our results of

57

Table of Contents

operations. For example, if a leak or spill of hazardous substances or petroleum products occurs from pipelines or facilities that ONEOK Partners owns, operates or otherwise uses, ONEOK Partners could be held jointly and severally liable for all resulting liabilities, including response, investigation and cleanup costs, which could affect materially our results of operations and cash flows. In addition, emissions controls and/or other regulatory or permitting mandates under the Clean Air Act and other similar federal and state laws could require unexpected capital expenditures at ONEOK Partners’ facilities. We cannot assure that existing environmental statutes and regulations will not be revised or that new regulations will not be adopted or become applicable to ONEOK Partners.

Additional information about our regulatory, environmental and safety matters can be found in “Regulatory, Environmental and Safety Matters” under Part I, Item 1, Business, in our Annual Report.

IMPACT OF NEW ACCOUNTING STANDARDS

See Note A of the Notes to Consolidated Financial Statements in this Quarterly Report for discussion of new accounting standards.

ESTIMATES AND CRITICAL ACCOUNTING POLICIES

The preparation of our consolidated financial statements and related disclosures in accordance with GAAP requires us to make estimates and assumptions with respect to values or conditions that cannot be known with certainty that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements. These estimates and assumptions also affect the reported amounts of revenue and expenses during the reporting period. Although we believe these estimates and assumptions are reasonable, actual results could differ from our estimates.

Information about our estimates and critical accounting policies is included under Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, “Estimates and Critical Accounting Policies,” in our Annual Report.

FORWARD-LOOKING STATEMENTS

Some of the statements contained and incorporated in this Quarterly Report are forward-looking statements as defined under federal securities laws. The forward-looking statements relate to our anticipated financial performance (including projected operating income, net income, capital expenditures, cash flow and projected levels of dividends and distributions), liquidity, management’s plans and objectives for our future growth projects and other future operations (including plans to construct additional natural gas and natural gas liquids pipelines and processing facilities and related cost estimates), our business prospects, the outcome of regulatory and legal proceedings, market conditions and other matters. We make these forward-looking statements in reliance on the safe harbor protections provided under federal securities legislation and other applicable laws. The following discussion is intended to identify important factors that could cause future outcomes to differ materially from those set forth in the forward-looking statements.

ITEM 3.
QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our quantitative and qualitative disclosures about market risk are consistent with those discussed in Part II, Item 7A, Quantitative and Qualitative Disclosures About Market Risk, in our Annual Report.

COMMODITY PRICE RISK

As part of its hedging strategy, ONEOK Partners uses commodity derivative financial instruments and physical-forward contracts described in “Financial Results and Operating Information” under the Natural Gas Gathering and Processing segment section in Item 2, Management’s Discussion and Analysis of Financial Condition and Results of Operations, to minimize the impact of near-term price fluctuations related to natural gas, NGLs and condensate.

ONEOK Partners is exposed to basis risk between the various production and market locations where it receives and sells commodities. Although ONEOK Partners’ businesses are predominately fee-based, in the Natural Gas Gathering and Processing segment, ONEOK Partners is exposed to commodity price risk as a result of receiving commodities as a portion of its compensation for services associated with its POP with fee contracts. ONEOK Partners has restructured a portion of its POP with fee contracts to include significantly higher fees, which reduces its equity volumes and the related commodity price exposure. However, under certain POP with fee contracts, ONEOK Partners’ fee revenues may increase or decrease if production volumes, delivery pressures or commodity prices change relative to specified thresholds.

We expect ONEOK Partners’ natural gas liquids and natural gas commodity price sensitivity within this segment to decrease in 2016, compared with 2015, as a result of the restructured contracts effective primarily in the fourth quarter 2015 and first quarter 2016. The Natural Gas Gathering and Processing segment’s commodity price sensitivity is estimated as a hypothetical change in the price of NGLs, crude oil and natural gas at June 30, 2016. Condensate sales are typically based on the price of crude oil. We estimate the following for ONEOK Partners’ forecasted equity volumes, including the effects of hedging information set forth above, and assuming normal operating conditions:
a $0.01 per-gallon change in the composite price of NGLs would change adjusted EBITDA for the six months ending December 31, 2016, and for the year ending December 31, 2017, by approximately $0.3 million and $1.0 million, respectively;
a $1.00 per-barrel change in the price of crude oil would change adjusted EBITDA for the six months ending December 31, 2016, and for the year ending December 31, 2017, by approximately $0.1 million and $0.4 million, respectively; and
a $0.10 per-MMBtu change in the price of residue natural gas would change adjusted EBITDA for the six months ending December 31, 2016, and for the year ending December 31, 2017, by approximately $0.1 million and $0.9 million, respectively.

These estimates do not include any effects on demand for ONEOK Partners’ services or natural gas processing plant operations that might be caused by, or arise in conjunction with, commodity price fluctuations. For example, a change in the gross processing spread may cause a change in the amount of ethane extracted from the natural gas stream, impacting gathering and processing financial results for certain contracts.

INTEREST-RATE RISK

We and ONEOK Partners are exposed to interest-rate risk through the ONEOK Credit Agreement, the ONEOK Partners Credit Agreement, ONEOK Partners’ commercial paper program and long-term debt issuances. Future increases in LIBOR, corporate commercial paper rates or corporate bond rates could expose us and ONEOK Partners to increased interest costs on future borrowings. We and ONEOK Partners manage interest-rate risk through the use of fixed-rate debt, floating-rate debt and interest-rate swaps. Interest-rate swaps are agreements to exchange interest payments at some future point based on specified notional amounts. As of June 30, 2016, ONEOK Partners had interest-rate swaps with notional amounts totaling $1.0 billion to hedge the variability of ONEOK Partners’ LIBOR-based interest payments. In June 2016, ONEOK Partners entered into forward-starting interest-rate swaps with notional amounts totaling $750 million to hedge the variability of interest payments on a portion of its forecasted debt issuances that may result from changes in the benchmark interest rate before the debt is issued. At June 30, 2016, and December 31, 2015, ONEOK Partners had forward-starting interest-rate swaps with notional amounts totaling $1.2 billion and $400 million, respectively, to hedge the variability of interest payments on a portion of its forecasted debt issuances. All of ONEOK Partners’ interest-rate swaps are designated as cash flow hedges. At June 30, 2016, ONEOK Partners had $70.1 million of derivative liabilities related to these interest-rate swaps. At December 31, 2015, ONEOK Partners had derivative liabilities of $9.9 million related to these interest-rate swaps.

COUNTERPARTY CREDIT RISK

ONEOK and ONEOK Partners assess the creditworthiness of their counterparties on an ongoing basis and require security, including prepayments and other forms of collateral, when appropriate. Certain of ONEOK Partners’ counterparties to the Natural Gas Gathering and Processing segment’s commodity sales, the Natural Gas Liquids segment’s marketing activities and the Natural Gas Pipelines segment’s storage activities may be impacted by the depressed commodity price environment and could experience financial problems, which could result in nonpayment and/or nonperformance, which could adversely impact our results of operations.

Customer concentration - For the six months ended June 30, 2016, one customer, BP p.l.c or its affiliates, represented more than 10 percent of our consolidated revenues, and 20 customers individually represented 1 percent or more of our consolidated revenues, the majority of which are investment-grade customers, as rated by S&P or Moody’s, or our comparable internal ratings, or secured by letters of credit or other collateral.

Natural Gas Gathering and Processing - The Natural Gas Gathering and Processing segment’s customers are crude oil and natural gas producers, which include both large integrated and independent exploration and production companies. ONEOK Partners is not typically exposed to material credit risk with exploration and production customers under POP with fee contracts as it receives proceeds from the sale of commodities and remits a portion of those proceeds back to the crude oil and natural gas producers. For the six months ended June 30, 2016, 99 percent of the downstream commodity sales in the Natural Gas Gathering and Processing segment were made to investment-grade customers, as rated by S&P or Moody’s, or our comparable internal ratings, or secured by letters of credit or other collateral.

Natural Gas Liquids - The Natural Gas Liquids segment’s customers are primarily NGL and natural gas gathering and processing companies; large integrated and independent crude oil and natural gas production companies; propane distributors; ethanol producers; and petrochemical, refining and NGL marketing companies. ONEOK Partners earns fee-based revenue from NGL and natural gas gathering and processing customers and natural gas liquids pipeline transportation customers. ONEOK Partners is not typically exposed to material credit risk on the majority of its exchange services fee revenues, as ONEOK Partners purchases NGLs from its gathering and processing customers and deducts fees from the amounts it remits. ONEOK Partners also earns sales revenue on the downstream sales of NGL products. For the six months ended June 30, 2016, approximately 85 percent of this segment’s commodity sales were made to investment-grade customers, as rated by S&P or Moody’s, or our comparable internal ratings, or secured by letters of credit or other collateral. In addition, the majority of the Natural Gas Liquids segment’s pipeline tariffs provide ONEOK Partners the ability to require security from shippers.

Natural Gas Pipelines - The Natural Gas Pipelines segment’s customers are primarily local natural gas distribution companies, electric-generation facilities, large industrial companies, municipalities, irrigation customers and marketing companies. For the six months ended June 30, 2016, approximately 90 percent of the revenues in this segment were from investment-grade customers, as rated by S&P or Moody’s, or our comparable internal ratings, or secured by letters of credit or other collateral. In addition, the majority of the Natural Gas Pipeline segment’s pipeline tariffs provide ONEOK Partners the ability to require security from shippers.

ITEM 4.

PART II - OTHER INFORMATION

ITEM 1.
LEGAL PROCEEDINGS

In May 2016, the Court entered an order granting summary judgment in favor of us and our affiliate ONEOK Energy Services Company, L.P., (“OESC”) in Reorganized FLI, Inc. (formerly J.P. Morgan Trust Company) v. ONEOK, Inc., et al. (filed in the District Court of Wyandotte County, Kansas, in October 2005, transferred to MDL 166 in the United States District Court for the District of Nevada). The Court determined that the plaintiff’s claim is barred by a release obtained in a prior lawsuit against us and OESC. Upon entry of a final judgment, Reorganized FLI, Inc. may pursue an appeal of this determination to the Ninth Circuit Court of Appeals.

In March 2016, we reached an agreement in principle to settle the claims alleged against us and our affiliates, OESC and Kansas Gas Marketing Company, in the following putative class action lawsuits that claimed damages resulting from alleged market manipulation or false reporting of prices to gas index publications by us and others: Learjet, Inc., et al. v. ONEOK, Inc., et al. (filed in the District Court of Wyandotte, Kansas, in November 2005, transferred to MDL-1566 in the United States District Court for the District of Nevada); Arandell Corporation, et al. v. Xcel Energy, Inc., et al. (filed in the Circuit Court for Dane County, Wisconsin, in December 2006, transferred to MDL-1566 in the United States District Court for the District of Nevada); Heartland Regional Medical Center, et al. v. ONEOK, Inc., et al. (filed in the Circuit Court of Buchanan County, Missouri, in March 2007, transferred to MDL-1566 in the United States District Court for the District of Nevada); and NewPage Wisconsin System v. CMS Energy Resource Management Company, et al. (filed in the Circuit Court for Wood County, Wisconsin, in March 2009, transferred to MDL-1566 in the United States District Court for the District of Nevada and now consolidated with the Arandell case). The amount we expect to pay to settle these cases is not material to our results of operations, financial position or cash flows and is expected to be paid with cash on hand.

This agreement in principle to settle does not apply to Sinclair Oil Corporation v. ONEOK Energy Services Corporation, L.P., et al. (filed in the United States District Court for the District of Wyoming in September 2005, transferred to MDL-1566 in the United States District Court for the District of Nevada). We expect that future charges, if any, from the ultimate resolution of this matter will not be material to our results of operations, financial position or cash flows.

Additional information about our legal proceedings is included under Part I, Item 3, Legal Proceedings, in our Annual Report.

ITEM 1A.
