BANCFIRST CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(1) | DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accounting and reporting policies of BancFirst Corporation and its subsidiaries (the “Company”) conform to accounting principles generally accepted in the United State of America (U.S. GAAP) and general practice within the banking industry. A summary of significant accounting policies can be found in Note (1) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.

Basis of Presentation

The accompanying unaudited interim consolidated financial statements include the accounts of BancFirst Corporation, Council Oak Partners, LLC, BancFirst Insurance Services, Inc. and BancFirst and its subsidiaries. The principal operating subsidiaries of BancFirst are Council Oak Investment Corporation, Council Oak Real Estate, Inc. and BancFirst Agency, Inc. All significant intercompany accounts and transactions have been eliminated. Assets held in a fiduciary or agency capacity are not assets of the Company and, accordingly, are not included in the unaudited interim consolidated financial statements.

The accompanying unaudited interim consolidated financial statements and notes are presented in accordance with the instructions for Form 10-Q. The information contained in the financial statements and footnotes included in BancFirst Corporation’s Annual Report on Form 10-K for the year ended December 31, 2014, should be referred to in connection with these unaudited interim consolidated financial statements. Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period.

The unaudited interim consolidated financial statements contained herein reflect all adjustments which are, in the opinion of management, necessary to provide a fair statement of the financial position and results of operations of the Company for the interim periods presented. All such adjustments are of a normal and recurring nature. There have been no significant changes in the accounting policies of the Company since December 31, 2014, the date of the most recent annual report.

Reclassifications

Certain items in prior financial statements have been reclassified to conform to the current presentation. Such reclassifications had no effect on previously reported cash flows, stockholders’ equity or comprehensive income.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the United States inherently involves the use of estimates and assumptions that affect the amounts reported in the financial statements and the related disclosures. These estimates relate principally to the determination of the allowance for loan losses, income taxes, the fair value of financial instruments and the valuation of intangibles.

In February 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-02, “Consolidation (Topic 810) – Amendments to the Consolidation Analysis.” ASU 2015-02 implements changes to both the variable interest consolidation model and the voting interest consolidation model. ASU 2015-02 (i) eliminates certain criteria that must be met when determining when fees paid to a decision maker or service provider do not represent a variable interest, (ii) amends the criteria for determining whether a limited partnership is a variable interest entity and (iii) eliminates the presumption that a general partner controls a limited partnership in the voting model. The amendments are effective for annual periods, and interim reporting periods within those annual periods, beginning after December 15, 2015. Adoption of ASU 2015-02 is not expected to have a significant effect on the Company’s financial statements.

In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements – Going Concern (Topic 205-40).” ASU 2014-15 provides guidance on management’s responsibility in evaluating whether there is substantial doubt about the Company’s ability to continue as a going concern and related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about the Company’s ability to continue as a going concern within one year from the date the financial statements are issued. The amendments are effective for annual periods, and

interim reporting periods within those annual periods, beginning after December 15, 2016. Early adoption is permitted. Adoption of ASU 2014-15 is not expected to have a significant effect on the Company’s financ ial statements.

In January 2014, the FASB issued Accounting Standards Update ASU No. 2014-04, “Receivables: Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (Topic 310-40).” ASU 2014-04 clarifies that an in-substance repossession or foreclosure occurs upon either the creditor obtaining legal title to the residential real estate property or the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. The amendments were effective for annual periods, and interim reporting periods within those annual periods, beginning after December 15, 2014. Adoption of ASU 2014-04 did not have a significant effect on the Company’s financial statements.

In January 2014, the FASB issued ASU No. 2014-01, “Accounting for Investments in Affordable Housing Projects (Topic 323).” ASU 2014-01 revises the necessary criteria that need to be met in order for an entity to account for investments in affordable housing projects net of the provision for income taxes. It also changes the method of recognition from an effective amortization approach to a proportional amortization approach. Additional disclosures were also set forth in this update. The amendments were effective for annual periods, and interim reporting periods within those annual periods, beginning after December 15, 2014. The amendments were required to be applied retrospectively to all periods presented. Early adoption was permitted and adoption of the standard was optional. Adoption of ASU 2014-01 did not have a material impact on the Company's financial statements.

The unrealized gains decreased in 2015 primarily due to the reclassification of an unrealized gain on one investment of $3.3 million from other comprehensive income to a realized gain by Council Oak Partners, LLC, a wholly-owned subsidiary of the Company. The realized gain is reported as securities transactions within the noninterest income section of the consolidated statement of comprehensive income.

The Company’s loans are mostly to customers within Oklahoma and over 65% of the loans are secured by real estate. Credit risk on loans is managed through limits on amounts loaned to individual borrowers, underwriting standards and loan monitoring procedures. The amounts and types of collateral obtained, if any, to secure loans are based upon the Company’s underwriting standards and management’s credit evaluation. Collateral varies, but may include real estate, equipment, accounts receivable, inventory, livestock and securities. The Company’s interest in collateral is secured through filing mortgages and liens, and in some cases, by possession of the collateral.

Accounting policies related to appraisals, nonaccruals and charge-offs are disclosed in Note (1) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.

Nonperforming and Restructured Assets

The following is a summary of nonperforming and restructured assets:

|  | (Dollars in thousands) |
Past due 90 days or more and still accruing |  | $ | 1,311 |  |  | $ | 1,135 |
Nonaccrual |  |  | 32,177 |  |  |  | 16,410 |
Restructured |  |  | 15,702 |  |  |  | 16,515 |

Total nonperforming and restructured assets |  | $ | 56,711 |  |  | $ | 42,139 |

Nonaccrual loans, accruing loans past due 90 days or more, and restructured loans are shown in the table above. Had nonaccrual loans performed in accordance with their original contractual terms, the Company would have recognized additional interest income of approximately $922,000 for the six months ended June 30, 2015 and approximately $481,000 for the six months ended June 30, 2014.

Restructured loans consisted primarily of one relationship restructured to defer principal payments. The relationship was evaluated by management and determined to be well collateralized. Additionally, none of the concessions granted involved a principal reduction or a change from the current market rate of interest. The collateral value is monitored periodically to evaluate possible impairment. The Company charges interest on principal balances outstanding during deferral periods. As a result, the current and future financial effects of the recorde d balance of loans considered to be restructured were not considered to be material.

Loans are segregated into classes based upon the nature of the collateral and the borrower. These classes are used to estimate the credit risk component in the allowance for loan losses.

The following table is a summary of amounts included in nonaccrual loans, segregated by class of loans. Residential real estate refers to one-to-four family real estate.

Impaired Loans

Loans are considered impaired when, based on current information and events, it is probable the Company will be unable to collect the full amount of scheduled principal and interest payments in accordance with the original contractual terms of the loan agreement. If a loan is impaired, a specific valuation allowance may be allocated if necessary so that the loan is reported, net of allowance for loss, at the present value of future cash flows using the loan’s existing rate, or the fair value of collateral if repayment is expected solely from the collateral.

The following table presents impaired loans, segregated by class of loans. No material amount of interest income was recognized on impaired loans subsequent to their classification as impaired.

Credit Risk Monitoring and Loan Grading

The Company considers various factors to monitor the credit risk in the loan portfolio including volume and severity of loan delinquencies, nonaccrual loans, internal grading of loans, historical loan loss experience and economic conditions.

An internal risk grading system is used to indicate the credit risk of loans. The loan grades used by the Company are for internal risk identification purposes and do not directly correlate to regulatory classification categories or any financial reporting definitions.

The general characteristics of the risk grades are disclosed in Note (5) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.

Additional information for intangible assets can be found in Note (7) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.

(6) | STOCK-BASED COMPENSATION

The Company adopted a nonqualified incentive stock option plan (the “BancFirst ISOP”) in May 1986. The Company amended the BancFirst ISOP to increase the number of shares to be issued under the plan to 3,000,000 shares in May 2013. At June 30, 2015, 39,485 shares were available for future grants. The BancFirst ISOP will terminate on December 31, 2019. The options are exercisable beginning four years from the date of grant at the rate of 25% per year for four years. Options expire at the end of fifteen years from the date of grant. Options outstanding as of June 30, 2015 will become exercisable through the year 2022. The option price must be no less than 100% of the fair value of the stock relating to such option at the date of grant.

In June 1999, the Company adopted the BancFirst Corporation Non-Employee Directors’ Stock Option Plan (the “BancFirst Directors’ Stock Option Plan”). Each non-employee director is granted an option for 10,000 shares. The Company amended the BancFirst Directors’ Stock Option Plan to increase the number of shares to be issued under the plan to 230,000 shares in May 2014. At June 30, 2015, 20,000 shares were available for future grants. The options are exercisable beginning one year from the date of grant at the rate of 25% per year for four years, and expire at the end of fifteen years from the date of grant. Options outstanding as of June 30, 2015 will become exercisable through the year 2018. The option price must be no less than 100% of the fair value of the stock relating to such option at the date of grant.

The Company currently uses newly issued stock to satisfy stock-based exercises, but reserves the right to use treasury stock purchased under the Company’s Stock Repurchase Program (the “SRP”) in the future.

The following table is a summary of the activity under both the BancFirst ISOP and the BancFirst Directors’ Stock Option Plan:

The following table has additional information regarding options granted and options exercised under both the BancFirst ISOP and the BancFirst Directors’ Stock Option Plan:

|  | Three Months Ended June 30, |  |  | Six Months Ended June 30, |
|  | 2015 |  |  | 2014 |  |  | 2015 |  |  | 2014 |
|  | (Dollars in thousands) |
Weighted average grant-date fair value per share of options granted |  | $ | 12.07 |  |  | $ | 12.33 |  |  | $ | 11.51 |  |  | $ | 12.33 |
Total intrinsic value of options exercised |  |  | 1,892 |  |  |  | 1,301 |  |  |  | 2,129 |  |  |  | 2,046 |
Cash received from options exercised |  |  | 1,109 |  |  |  | 776 |  |  |  | 1,353 |  |  |  | 1,642 |
Tax benefit realized from options exercised |  |  | 731 |  |  |  | 503 |  |  |  | 823 |  |  |  | 791 |

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model and is based on certain assumptions including risk-free rate of return, dividend yield, stock price volatility and the expected term. The fair value of each option is expensed over its vesting period.

The following table is a summary of the Company’s recorded stock-based compensation expense:

|  | Three Months Ended June 30, |  |  | Six Months Ended June 30, |
|  | 2015 |  |  | 2014 |  |  | 2015 |  |  | 2014 |

Stock-based compensation expense |  | $ | 290 |  |  | $ | 429 |  |  | $ | 754 |  |  | $ | 776 |
Tax benefit |  |  | 112 |  |  |  | 166 |  |  |  | 292 |  |  |  | 300 |
Stock-based compensation expense, net of tax |  | $ | 178 |  |  | $ | 263 |  |  | $ | 462 |  |  | $ | 476 |

The Company will continue to amortize the remaining fair value of stock options over the remaining vesting period of approximately seven years. The following table shows the remaining fair value of stock options:

|  | June 30, 2015 |
|  | (Dollars in thousands) |
Fair value of stock options |  | $ | 4,459 |

The following table shows the assumptions used for computing stock-based compensation expense under the fair value method during the periods presented:

|  | Six Months Ended June 30,
|  | 2015 |  | 2014
Risk-free interest rate |  | 1.83 to 2.26% |  | 2.54%
Dividend yield |  | 2.00% |  | 2.00%
Stock price volatility |  | 18.23 to 19.22% |  | 18.98%
Expected term |  | 10 Yrs |  | 10 Yrs

The risk-free interest rate is determined by reference to the spot zero-coupon rate for the U.S. Treasury security with a maturity similar to the expected term of the options. The dividend yield is the expected yield for the expected term. The stock price volatility is estimated from the recent historical volatility of the Company’s stock. The expected term is estimated from the historical option exercise experience.

(7) | STOCKHOLDERS’ EQUITY

In November 1999, the Company adopted a Stock Repurchase Program (the “SRP”). The SRP may be used as a means to increase earnings per share and return on equity, to purchase treasury stock for the exercise of stock options or for distributions under the Deferred Stock Compensation Plan, to provide liquidity for optionees to dispose of stock from exercises of their stock options and to provide liquidity for stockholders wishing to sell their stock. All shares repurchased under the SRP have been retired and not held as treasury stock. The timing, price and amount of stock repurchases under the SRP may be determined by management and approved by the Company’s Executive Committee.

The Company and BancFirst are subject to risk-based capital guidelines issued by the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation (“FDIC”). These guidelines are used to evaluate capital adequacy and involve both quantitative and qualitative evaluations of the Company’s and BancFirst’s assets, liabilities and certain off-balance-sheet items calculated under regulatory practices. Failure to meet the minimum capital requirements can initiate certain mandatory or discretionary actions by the regulatory agencies that could have a direct material effect on the Company’s financial statements. Management believes that as of June 30, 2015, the Company and BancFirst met all capital adequacy requirements to which they are subject. The actual and required capital amounts and ratios are shown in the following table:

|  |  |  |  |  |  |  |  |  | Required |  |  | To Be Well |
|  |  |  |  |  |  |  |  |  | For Capital |  |  | Capitalized Under |

As of June 30, 2015, the most recent notification from the Federal Reserve Bank of Kansas City and the FDIC categorized BancFirst as “well capitalized” under the regulatory framework from prompt corrective action. The Company’s trust preferred securities have continued to be included in Tier 1 capital as the Company’s total assets do not exceed $15 billion. There are no conditions or events since the most recent notifications of BancFirst’s capital category that management believes would materially change its category under capital requirements existing as of the report date.

Basel III Capital Rules

The Basel III Capital Rules were effective for the Company and BancFirst on January 1, 2015 (subject to a 4-year phase-in period).

The Basel III Capital Rules, among other things, (i) introduce a new capital measure called “Common Equity Tier 1” (“CET1”), (ii) specify that Tier 1 capital consist of CET1 and “Additional Tier 1 capital” instruments meeting specified requirements, (iii) define CET1 narrowly by requiring that most deductions/adjustments to regulatory capital measures be made to CET1 and not to the other components of capital and (iv) expand the scope of the deductions/adjustments as compared to existing regulations.

Implementation of the deductions and other adjustments to CET1 began on January 1, 2015 and will be phased-in over a 4-year period (beginning at 40% on January 1, 2015 and an additional 20% per year thereafter). Under the new rule, in order to avoid limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers, a banking organization must hold a capital conservation buffer composed of CET1 capital above its minimum risk-based capital

18

requirements. The implementation of the capital conservation buffer will begin on January 1, 2016 at the 0.625% level and be phased in over a four-year pe riod (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019).

Management believes that, as of June 30, 2015, the Company and BancFirst would meet all capital adequacy requirements under the Basel III Capital Rules on a fully phased-in basis as if such requirements were currently in effect.

(9) | FAIR VALUE MEASUREMENTS

Accounting standards define fair value as the price that would be received to sell an asset or the price paid to transfer a liability in the principal or most advantageous market available to the entity in an orderly transaction between market participants on the measurement date.

FASB ASC Topic 820 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

· | Level 1 Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

· | Level 2 Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset and liability, either directly or indirectly, for substantially the full term of the financial instrument.

· | Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. This category includes certain impaired loans, foreclosed assets, other real estate, goodwill and other intangible assets.

Financial Assets and Financial Liabilities Measured at Fair Value on a Recurring Basis

A description of the valuation methodologies and key inputs used to measure financial assets and financial liabilities at fair value on a recurring basis, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to the following categories of the Company’s financial assets and financial liabilities.

Securities Available for Sale

Securities classified as available for sale are reported at fair value. U.S. Treasuries are valued using Level 1 inputs. Other securities available for sale including U.S. federal agencies, registered mortgage backed securities and state and political subdivisions are valued using prices from an independent pricing service utilizing Level 2 data. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. The Company also invests in private label mortgage backed securities and equity securities classified as available for sale for which observable information is not readily available. These securities are reported at fair value utilizing Level 3 inputs. For these securities, management determines the fair value based on replacement cost, the income approach or information provided by outside consultants or lead investors.

The Company reviews the prices for Level 1 and Level 2 securities supplied by the independent pricing service for reasonableness and to ensure such prices are aligned with traditional pricing matrices. In general, the Company does not purchase investment portfolio securities that are esoteric or that have complicated structures. The Company’s entire portfolio consists of traditional investments including U.S. Treasury obligations, federal agency mortgage pass-through securities, general obligation municipal bonds and a small amount of municipal revenue bonds. Pricing for such instruments is fairly generic and is easily obtained. For in-state bond issues that have relatively low issue sizes and liquidity, the Company utilizes the same parameters for pricing mentioned in the preceding paragraph adjusted for the specific issue. From time to time, the Company will validate, on a sample basis, prices supplied by the independent pricing service by comparison to prices obtained from third party sources.

Derivatives

Derivatives are reported at fair value utilizing Level 2 inputs. The Company obtains dealer and market quotations to value its oil and gas swaps and options. The Company utilizes dealer quotes and observable market data inputs to substantiate internal valuation models.

Loans Held For Sale

The Company originates mortgage loans to be sold. At the time of origination, the acquiring bank has already been determined and the terms of the loan, including interest rate, have already been set by the acquiring bank, allowing the Company to originate the loan at fair value. Mortgage loans are generally sold within 30 days of origination. Loans held for sale are valued using Level 2 inputs. Gains or losses recognized upon the sale of the loans are determined on a specific identification basis.

20

Mortgage Servicing Intangibles

The Company acquired mortgage servicing intangibles with the acquisition of 1st Bank Oklahoma on July 12, 2011. Mortgage Servicing Intangibles are amortized based on current prepayment assumptions and are adjusted to fair value semi-annually, if impaired. Fair value is estimated based on the present value of future cash flows over several interest rate scenarios, which are then discounted at risk-adjusted rates. The Company considers portfolio characteristics, contractually specified servicing fees, prepayment assumptions, delinquency rates, late charges, other ancillary revenue, costs to service and other economic factors. When available, fair value estimates and assumptions are compared to observable market data and the recent market activity and actual portfolio experience.

The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of the periods presented, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value:

Financial Assets and Financial Liabilities Measured at Fair Value on a Nonrecurring Basis

Certain financial assets and financial liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). These financial assets and financial liabilities are reported at fair value utilizing Level 3 inputs.

Impaired loans are reported at the fair value of the underlying collateral if repayment is dependent on liquidation of the collateral. In no case does the fair value of an impaired loan exceed the fair value of the underlying collateral. The impaired loans are adjusted to fair value through a specific allocation of the allowance for loan losses or a direct charge-down of the loan.

Foreclosed assets, upon initial recognition, are measured and adjusted to fair value through a charge-off to the allowance for possible loan losses based upon the fair value of the foreclosed asset.

Other real estate owned is revalued at fair value subsequent to initial recognition, with any losses recognized in net expense from other real estate owned.

The following table summarizes assets measured at fair value on a nonrecurring basis and the related losses recognized during the period:

|  | Total Fair Value Level 3 |  |  | Losses |
|  | (Dollars in thousands) |
As of and for the Year-to-date Period Ended June 30, 2015 |  |  |  |  |  |  |  |

Estimated Fair Value of Financial Instruments

The Company is required under current authoritative accounting guidance to disclose the estimated fair value of their financial instruments that are not recorded at fair value. For the Company, as for most financial institutions, substantially all of its assets and liabilities are considered financial instruments. A financial instrument is defined as cash, evidence of an ownership interest in an entity or a contract that creates a contractual obligation or right to deliver or receive cash or another financial instrument from a second entity. The following methods and assumptions were used to estimate the fair value of each class of financial instruments:

Cash and Cash Equivalents Include: Cash and Due from Banks; Federal Funds Sold and Interest-Bearing Deposits

The carrying amount of these short-term instruments is a reasonable estimate of fair value.

Securities Held for Investment

For securities held for investment, which are generally traded in secondary markets, fair values are based on quoted market prices or dealer quotes, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities making adjustments for credit or liquidity if applicable.

Loans

For certain homogeneous categories of loans, such as some residential mortgages, fair values are estimated using the quoted market prices for securities backed by similar loans, adjusted for differences in loan characteristics. The fair values of other types of loans are estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities.

Deposits

The fair values of transaction and savings accounts are the amounts payable on demand at the reporting date. The fair values of fixed-maturity certificates of deposit are estimated using the rates currently offered for deposits of similar remaining maturities.

22

Short-term Borrowings

The amounts payable on these short-term instruments are reasonable estimates of fair value.

Long-term Borrowings

The fair values of fixed-rate long-term borrowings are estimated using the rates that would be charged for borrowings of similar remaining maturities.

Junior Subordinated Debentures

The fair values of junior subordinated debentures are estimated using the rates that would be charged for junior subordinated debentures of similar remaining maturities.

Loan Commitments and Letters of Credit

The fair values of commitments are estimated using the fees currently charged to enter into similar agreements, taking into account the terms of the agreements. The fair values of letters of credit are based on fees currently charged for similar agreements.

The estimated fair values of the Company’s financial instruments that are reported at amortized cost in the Company’s consolidated balance sheets, segregated by the level of valuation inputs within the fair value hierarchy utilized to measure fair value, are as follows:

|  | June 30, |  |  | December 31, |

Non-financial Assets and Non-financial Liabilities Measured at Fair Value

The Company has no non-financial assets or non-financial liabilities measured at fair value on a recurring basis. Certain non-financial assets and non-financial liabilities measured at fair value on a nonrecurring basis include intangible assets (excluding mortgage service rights, which are valued semi-annually) and other non-financial long-lived assets measured at fair value and adjusted for impairment. These items are evaluated at least annually for impairment. The overall levels of non-financial assets and non-financial liabilities measured at fair value on a nonrecurring basis were not considered to be significant to the Company at June 30, 2015 or December 31, 2014.

(10) | DERIVATIVE FINANCIAL INSTRUMENTS

The Company enters into oil and gas swaps and options contracts to accommodate the business needs of its customers. Upon the origination of an oil or gas swap or option contract with a customer, the Company simultaneously enters into an offsetting contract with a counterparty to mitigate the exposure to fluctuations in oil and gas prices. These derivatives are not designated as hedged instruments and are recorded on the Company’s consolidated balance sheet at fair value.

23

The Company utilizes dealer quotations and observable market data inputs to substantiate internal v aluation models. The notional amounts and estimated fair values of oil and gas derivative positions outstanding are presented in the following table:

|  |  |  | June 30, 2015 |  |  | December 31, 2014 |

The following table is a summary of the Company’s recognized income related to the activity, which was included in other noninterest income:

|  | Three Months Ended June 30, |  |  | Six Months Ended June 30, |
|  | 2015 |  |  | 2014 |  |  | 2015 |  |  | 2014 |
|  | (Dollars in thousands) |
Derivative income |  | $ | 37 |  |  | $ | 149 |  |  | $ | 192 |  |  | $ | 298 |

The Company’s credit exposure on oil and gas swaps and options varies based on the current market prices of oil and natural gas. Other than credit risk, changes in the fair value of customer positions will be offset by equal and opposite changes in the counterparty positions. The net positive fair value of the contracts is the profit derived from the activity and is unaffected by market price movements. The Company’s share of total profit is approximately 35%.

Customer credit exposure is managed by strict position limits and is primarily offset by first liens on production while the remainder is offset by cash. Counterparty credit exposure is managed by selecting highly rated counterparties (rated A- or better by Standard and Poor’s) and monitoring market information.

The following table is a summary of the Company’s net credit exposure relating to oil and gas swaps and options with bank counterparties:

|  | June 30, 2015 |  |  | December 31, 2014 |
|  | (Dollars in thousands) |
Credit exposure |  | $ | 1,503 |  |  | $ | 4,028 |

Balance Sheet Offsetting

Derivatives may be eligible for offset in the consolidated balance sheet and/or subject to master netting arrangements. The Company’s derivative transactions with upstream financial institution counterparties and bank customers are generally executed under International Swaps and Derivative Association (“ISDA”) master agreements which include “right of set-off” provisions. In such cases there is generally a legally enforceable right to offset recognized amounts and there may be an intention to settle such amounts on a net basis. Nonetheless, the Company does not generally offset such financial instruments for financial reporting purposes.

(11) | SEGMENT INFORMATION

The Company evaluates its performance with an internal profitability measurement system that measures the profitability of its business units on a pre-tax basis.

The financial information for each business unit is presented on the basis used internally by management to evaluate performance and allocate resources. The Company utilizes a transfer pricing system to allocate the benefit or cost of funds provided or used by the various business units. Certain services provided by the support group to other business units, such as item processing, are allocated at rates approximating the cost of providing the services. Eliminations are adjustments to consolidate the business units and companies. Capital expenditures are generally charged to the business unit using the asset.

(12) SUBSEQUENT EVENT

On July 14, 2015, the Company announced it had entered into an agreement to acquire CSB Bancshares Inc. and its subsidiary bank, Bank of Commerce, with locations in Yukon, Mustang, and El Reno, Oklahoma. Bank of Commerce has approximately $202 million in total assets, $139 million in loans, $180 million in deposits, and $21 million in equity capital. The transaction is scheduled to be completed during October 2015, and is subject to regulatory approval. The bank will operate under its present name until it is merged into BancFirst, which is expected to be during the fourth quarter of 2015. The acquisition will not have a material effect on the Company’s consolidated financial statements.

SUMMARY

BancFirst Corporation’s net income was $18.6 million, or $1.17 diluted earnings per share, for the second quarter of 2015, compared to net income of $14.7 million, or $0.92 diluted earnings per share, for the second quarter of 2014. Net income was $34.8 million, or $2.20 diluted earnings per share for the six months ended June 30, 2015, compared to $29.3 million, or $1.86 diluted earnings per share, for the six months ended June 30, 2014.

The Company’s net interest income for the second quarter of 2015 increased to $46.2 million, compared to $45.5 million for the second quarter of 2014, due to higher volume of earning assets. The net interest margin for the quarter was 3.07%, compared to 3.10% a year ago. The Company’s provision for loan losses for the second quarter of 2015 decreased to $1.3 million, compared to $3.1 million a year ago. The higher provision for loan losses in the second quarter of 2014 was due in part to an additional $2 million allowance for a single commercial loan that was adversely graded during the quarter. Net charge-offs for the quarter were only 0.01% of average loans, compared to net recoveries of 0.01% for the second quarter of 2014. Noninterest income for the quarter totaled $28.7 million, compared to $23.6 million last year. Noninterest income increased due to the Company recording a gain from the sale of an investment by the Company’s wholly-owned subsidiary, Council Oak Partners, LLC, of approximately $5.3 million. Noninterest expense for the quarter totaled $45.4 million, compared to $45.9 million last year. The Company recorded a goodwill impairment loss of approximately $368,000, which is included in noninterest expense for the second quarter of 2015. The Company’s effective tax rate increased to 34.3% compared to 27.0% for the second quarter of 2014, due primarily to tax credits purchased in 2014 that lowered the effective tax rate.

At June 30, 2015, the Company’s total assets were $6.5 billion, largely unchanged from December 31, 2014. Securities increased $12.5 million to a total of $537.3 million. Loans totaled $3.8 billion, a slight increase from December 31, 2014. Deposits totaled $5.8 billion, virtually flat from December 31, 2014. The Company’s total stockholders’ equity was $634.2 million, an increase of $24.9 million, or 4.1%, over December 31, 2014.

Asset quality remained strong during the second quarter of 2015. Nonperforming and restructured assets were 0.87% of total assets at June 30, 2015 compared to 0.64% at December 31, 2014. During the second quarter the Company’s nonaccrual loans increased due to the downgrade of a single commercial loan. The allowance to total loans was 1.10%, compared to 1.06% at year-end 2014.

On July 14, 2015 the Company announced it had entered into an agreement to acquire CSB Bancshares Inc. and its subsidiary bank, Bank of Commerce, with locations in Yukon, Mustang, and El Reno, Oklahoma. Bank of Commerce has approximately $202 million in total assets, $139 million in loans, $180 million in deposits, and $21 million in equity capital. The transaction is scheduled to be completed during October 2015, and is subject to regulatory approval. The bank will operate under its present name until it is merged into BancFirst, which is expected to be during the fourth quarter of 2015. The acquisition will not have a material effect on the Company’s consolidated financial statements.

Oil prices continued to be low during the second quarter of 2015, which had an impact on our loan demand. We expect any continued impact from low oil prices on Oklahoma’s economy will become more apparent in future periods.

Net Interest Income

For the three months ended June 30, 2015, net interest income, which is the Company’s principal source of operating revenue, increased to $46.2 million compared to $45.5 million for the three months ended June 30, 2014, due to higher volume of earning assets. Net interest margin is the ratio of taxable-equivalent net interest income to average earning assets for the period. The Company’s net interest margin for the quarter was 3.07% compared to 3.10% a year ago. If interest rates and/or loan volume do not increase, management would expect its net interest margin to continue to compress in 2015 as higher yielding loans and securities mature and are replaced at current market rates.

Net interest income for the six months ended June 30, 2015 was $91.8 million compared to $87.5 million for the six months ended June 30, 2014. The net interest margin for the year-to-date increased slightly compared to the same period of the previous year, as shown in the preceding table.

Provision for Loan Losses

The Company’s provision for loan loss for the second quarter of 2015 decreased to $1.3 million compared to $3.1 million a year ago. The higher provision for loan losses in the second quarter of 2014 was due in part to an additional $2 million allowance for a single commercial loan that was adversely graded during the quarter. The Company establishes an allowance as an estimate of the probable inherent losses in the loan portfolio at the balance sheet date. Management believes the allowance for loan losses is appropriate based upon management’s best estimate of probable losses that have been incurred within the existing loan portfolio. Should any of the factors considered by management in evaluating the appropriate level of the allowance for loan losses change, the Company’s estimate of probable loan losses could also change, which could affect the amount of future provisions for loan losses. Net loan charge-offs were $207,000 for the second quarter of 2015, compared to net recoveries of $244,000 for the second quarter of 2014. The rate of net charge-offs to average total loans, as presented in the preceding table, continues to be at a very low level.

28

For the six months ended June 30, 201 5, the Company’s provision for loan losses was $2.6 million, compared to $4.3 million for the six months ended June 30, 201 4. Net loan charge-offs were $8 73,000, compared to $84,000 for the same period of the prior year.

Noninterest Income

Noninterest income totaled $28.7 million for the second quarter of 2015 compared to $23.6 million for the second quarter of 2014. Noninterest income increased due to the Company recording a gain from the sale of an investment by the Company’s wholly-owned subsidiary Council Oak Partners, LLC, of approximately $5.3 million. The Company had fees from debit card usage totaling $5.8 million and $5.7 million during the three month periods ended June 30, 2015 and 2014, respectively.

Noninterest income for the six months ended June 30, 2015 totaled $54.0 million compared to $47.2 million for the six months ended June 30, 2014. Noninterest income increased due to the Company recording a gain from the sale of an investment by the Company’s wholly-owned subsidiary Council Oak Partners, LLC, of approximately $5.3 million and a $1.7 million gain on the sale of an investment by Council Oak Investment Corporation, a wholly-owned subsidiary of BancFirst. Fees from debit card usage totaled $11.3 million and $11.1 million during the six months ended June 30, 2015 and 2014, respectively.

Noninterest Expense

For the three months ended June 30, 2015, noninterest expense totaled $45.4 million, compared to $45.9 million for the three months ended June 30, 2014. The Company recorded an impairment loss of $368,000, which is included in noninterest expense, after adopting a plan in the second quarter of 2015 to close a small branch and leave a full service ATM to serve the community. Noninterest expense for the second quarter of 2014 included acquisition costs for The Bank of Union of $1.6 million partly offset by a gain on sale of other real estate owned property of approximately $500,000.

For the six months ended June 30, 2015, noninterest expense totaled $90.4 million compared to $89.7 million for the six months ended June 30, 2014. The increase in noninterest expense for year-to-date 2015 was mainly due to annual salary increases. Noninterest expense for year-to-date 2014 included acquisition costs of $2.0 million for The Bank of Union, partly offset by a gain on sale of other real estate owned property of approximately $500,000.

Income Taxes

The Company’s effective tax rate on income before taxes increased to 34.3% for the second quarter of 2015, compared to 27.0% for the second quarter of 2014, due primarily to tax credits purchased in 2014 that lowered the effective tax rate.

The Company’s effective tax rate on income before taxes was 34.2% for the first six months of 2015, compared to 27.8% for the first six months of 2014 due primarily to tax credit purchased in 2014 that lowered the effective tax rate and the recognition of state deferred tax benefits in 2014.

Cash, Federal Funds Sold and Interest-Bearing Deposits with Banks

The aggregate of cash and due from banks, interest-bearing deposits with banks, and federal funds sold as of June 30, 2015 totaled $1.8 billion, virtually flat from December 31, 2014. Federal funds sold consist of overnight investments of excess funds with other financial institutions. Due to the Federal Reserve Bank’s intervention into the funds market that has resulted in near zero overnight federal funds rates, the Company has continued to maintain the majority of its excess funds with the Federal Reserve Bank. The Federal Reserve Bank pays interest on these funds based upon the lowest target rate for the maintenance period which continues to be 0.25%.

Securities

At June 30, 2015, total securities increased $12.5 million compared to December 31, 2014. The size of the Company’s securities portfolio is determined by the Company’s liquidity and asset/liability management. The net unrealized gain on securities available for sale, before taxes, was $4.0 million at June 30, 2015, compared to an unrealized gain of $6.8 million at December 31, 2014. These unrealized gains are included in the Company’s stockholders’ equity as accumulated other comprehensive income, net of income tax, in the amounts of $2.5 million and $4.2 million, respectively. The unrealized gains decreased in 2015 primarily due to the reclassification of an unrealized gain on one investment of $3.3 million from other comprehensive income to realized gain by Council Oak Partners, LLC, a wholly-owned subsidiary of the Company. The realized gain is reported as securities transactions within the noninterest income section of the consolidated statement of comprehensive income.

Loans (Including Acquired Loans)

At June 30, 2015, loans totaled $3.9 billion, with no material change from December 31, 2014. Loan growth during the first half of 2015 slowed in part due to the effect of lower oil prices on the Oklahoma economy.

30

Allowance for Loan Losses/Fair Value Adjustments on Acquired Loans

At June 30, 2015, the allowance for loan losses to total loans represented 1.10% of total loans, compared to 1.06% at December 31, 2014. The increase was mainly due to higher adversely classified loans.

The fair value adjustment on acquired loans consists of an interest rate component to adjust the effective rates on the loans to market rates and a credit component to adjust for estimated credit exposures in the acquired loans. The credit component of the adjustment was $3.5 million at June 30, 2015 and $4.3 million at December 31, 2014 while the acquired loans outstanding were $86.2 million and $101.7 million, respectively. The decrease in the credit component in 2015 was due to loan payoffs and accretion.

Nonperforming and Restructured Assets

Nonperforming and restructured assets totaled $56.7 million at June 30, 2015, compared to $42.1 million at December 31, 2014. The Company’s level of nonperforming and restructured assets has continued to be relatively low.

Nonaccrual loans totaled $32.2 million at June 30, 2015, compared to $16.4 million at the end of 2014. The Company’s nonaccrual loans are primarily commercial and real estate loans. Nonaccrual loans negatively impact the Company’s net interest margin. A loan is placed on nonaccrual status when, in the opinion of management, the future collectability of interest or principal or both is in serious doubt. Interest income is recognized on certain of these loans on a cash basis if the full collection of the remaining principal balance is reasonably expected. Otherwise, interest income is not recognized until the principal balance is fully collected. Total interest income which was not accrued on nonaccrual loans outstanding, was approximately $922,000 for the six months ended June 30, 2015 and $481,000 for the six months ended June 30, 2014. Only a small amount of this interest is expected to be ultimately collected. During the second quarter of 2015 the Company’s nonaccrual loans increased due to the downgrade of a single commercial loan.

Other real estate owned and repossessed assets totaled $7.5 million at June 30, 2015, compared to $8.1 million at December 31, 2014. Other real estate owned and repossessed assets decreased due to the sale of two properties during the first quarter of 2015, partially offset by an addition in the second quarter.

Potential problem loans are performing loans to borrowers with a weakened financial condition, or which are experiencing unfavorable trends in their financial condition, which causes management to have concerns as to the ability of such borrowers to comply with the existing repayment terms. The Company had approximately $7.6 million of these loans at June 30, 2015, compared to $27.5 million at December 31, 2014. Potential problem loans are not included in nonperforming and restructured loans. In general, these loans are adequately collateralized and have no specific identifiable probable loss. Loans which are considered to have identifiable probable loss potential are placed on nonaccrual status, are allocated a specific allowance for loss or are directly charged-down, and are reported as nonperforming. Potential problem loans decreased due to the downgrade of a single commercial loan that was moved to nonaccrual during the second quarter.

Liquidity and Funding

Deposits

At June 30, 2015, deposits totaled $5.8 billion, virtually flat compared to December 31, 2014. The Company’s core deposits provide it with a stable, low-cost funding source. The Company’s core deposits as a percentage of total deposits were 94.2% at June 30, 2015 compared to 94.1% at December 31, 2014. Noninterest-bearing deposits to total deposits were 40.0% at June 30, 2015, compared to 40.8% at December 31, 2014.

Short-Term Borrowings

Short-term borrowings, consisting primarily of federal funds purchased and repurchase agreements are another source of funds for the Company. The level of these borrowings is determined by various factors, including customer demand and the Company’s ability to earn a favorable spread on the funds obtained. Short-term borrowings were $2.1 million at June 30, 2015, compared to $4.0 million at December 31, 2014.

Long-Term Borrowings

The Company has a line of credit from the Federal Home Loan Bank (“FHLB”) of Topeka, Kansas to use for liquidity or to match-fund certain long-term fixed rate loans. The Company’s assets, including residential first mortgages of $637.6 million, are pledged as collateral for the borrowings under the line of credit. As of June 30, 2015 and December 31, 2014, the Company had no advances outstanding.

31

There have not been any other material changes from the liquid ity and funding discussion included in Management’s Discussion and Analysis in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.

Capital Resources

Stockholders’ equity totaled $634.2 million at June 30, 2015, compared to $609.3 million at December 31, 2014. In addition to net income of $34.8 million, other changes in stockholders’ equity during the six months ended June 30, 2015 included $1.7 million related to stock option exercises and $754,000 related to stock-based compensation that were partially offset by a $1.7 million decrease in other comprehensive income and $10.6 million in dividends. The Company’s leverage ratio and total risk-based capital ratios at June 30, 2015, were well in excess of the regulatory requirements.

See Note (7) of the Notes to Consolidated Financial Statements for a discussion of capital ratio requirements.

CONTRACTUAL OBLIGATIONS

There have not been any material changes in the resources required for scheduled repayments of contractual obligations from the table of Contractual Cash Obligations included in Management’s Discussion and Analysis which was included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014.
