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, 2017.

Basis of Presentation

The accompanying unaudited interim consolidated financial statements include the accounts of BancFirst Corporation, First Bank of Chandler, Council Oak Partners, LLC, BancFirst Insurance Services, Inc., BancFirst Risk and Insurance Company 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, 2017, 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, 2017, 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. Such estimates and assumptions may change over time and actual amounts realized may differ from those reported.

Recent Accounting Pronouncements

Standards Adopted During Current Period:

In February 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-2, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. ASU 2018-2 allows a reclassification from accumulated other comprehensive income (loss) to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. ASU 2018-2 is effective for fiscal years beginning after December 15, 2018 with early adoption permitted. The Company elected to early adopt the provisions of ASU 2018-2 and the amount to reclassify was immaterial to the Company’s financial statements. The Company’s policy is to release material stranded tax effects on a specific identification basis.

In May 2017, the FASB issued ASU No. 2017-09, “Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting.” The amendments in this update provide guidance about types of changes to the terms of conditions of share-based payment awards that would require an entity to apply modification accounting under ASC 718. ASU 2017-09 was adopted on January 1, 2018 and did not have a significant impact on the Company’s financial statements and no prior periods were adjusted.

In January 2017, the FASB issued ASU No. 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Good will Impairment.” ASU 2017-04 removes the second step of goodwill testing. ASU 2017-04 is effective for fiscal years beginning after December 31, 2019 with early adoption permitted. The Company elected to early adopt ASU 2017-4 and it did not have a significant impact on the Company’s financial statements .

In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business.” ASU 2017-01 clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of a business. ASU 2017-01 was adopted on January 1, 2018 and did not have a significant impact on the Company’s financial statements.

In October 2016, the FASB issued ASU No. 2016-16, “Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory.” ASU 2016-16 provides guidance stating that an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. ASU 2016-16 was adopted on January 1, 2018 and did not have a significant impact on the Company’s financial statements and no prior periods were adjusted.

In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments.” ASU 2016-15 is intended to reduce the diversity in practice around how certain transactions are classified within the statement of cash flows. ASU 2016-15 was adopted on January 1, 2018 and did not have a significant impact on the Company’s financial statements.

In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments – Overall (Subtopic 825-10).” ASU 2016-01 requires all equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in the fair value recognized through net income. The adoption of the guidance resulted in a $618,000 decrease to retained earnings and a $618,000 increase to accumulated other comprehensive income. Additional income of $41,200 was recorded in the consolidated statement of comprehensive income during 2018 as a result of changes to the accounting for equity investments. Further, the Company’s securities disclosures in Note (3) have been revised to exclude equity investments in 2018 and fair value disclosures in Note (9) have incorporated the revised disclosure requirements for financial investments. ASU 2016-01 also emphasizes the existing requirement to use exit prices to measure fair value for disclosure purposes and clarifies that entities should not make use of a practicability exception in determining the fair value of loans. Accordingly, we refined the calculation used to determine the disclosed fair value of the Company’s loans held for investment as part of adopting this standard. The refined calculation did not have a significant impact on the Company’s fair value disclosures. ASU 2016-01 was adopted on January 1, 2018 and did not have a significant impact on the Company’s financial statements.

In January 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customer (Topic 606).” ASU 2014-09 implements a comprehensive new revenue recognition standard that will supersede substantially all existing revenue recognition guidance. The new standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in a manner that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, which comprises a significant portion of the Company’s revenue stream. ASU 2014-09 was adopted on January 1, 2018 and did not have a significant impact on the Company’s financial statements.

Standards Not Yet Adopted:

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires a financial asset measured at amortized cost basis to be presented at the net amount expected to be collected. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. ASU 2016-13 requires enhanced disclosures related to the significant estimates and judgements used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. In addition, ASU 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. ASU 2016-13 will be effective for the Company on January 1, 2020. The Company is currently evaluating the potential impact of ASU 2016-13 on its financial statements. In that regard, the Company has formed a task force under the direction of its Chief Financial Officer. The Company is currently developing an implementation plan to include assessment of process, portfolio segmentation, model development, system requirements and the identification of data and resource need, among other things.

In February 2016, the FASB issued ASU No. 2016-02, “Leases - (Topic 842).” ASU 2016-02 requires that lessees recognize on the balance sheet the assets and liabilities for the rights and obligations created by leases. The amendments are effective for annual periods, and interim reporting periods within those annual periods, beginning after December 15, 2018. Early adoption is permitted. Adoption of ASU 2016-02 is not expected to have a significant effect on the Company’s financial statements.

(2) RECENT DEVELOPMENTS, INCLUDING MERGERS AND ACQUISITIONS

On January 11, 2018, the Company acquired First Wagoner Corp. and its subsidiary bank, First Bank & Trust Company, with locations in Carney, Grove, Ketchum, Luther, Tulsa and Wagoner. First Bank & Trust Company had approximately $290 million in total assets, $247 million in loans, $251 million in deposits and $36 million in equity capital. First Bank & Trust Company operated as a subsidiary of BancFirst Corporation until it was merged into BancFirst on February 16, 2018. As a result of the acquisition, the Company recorded a core deposit intangible of approximately $6.3 million and goodwill of approximately $19.1 million. These fair value estimates are considered preliminary and are subject to change for up to one year after the closing date of the acquisition as additional information becomes available. The effect of this acquisition was included in the consolidated financial statements of the Company from the date of acquisition forward. The acquisition did not have a material effect on the Company’s consolidated financial statements. The acquisition of First Wagoner Corp. and its subsidiary bank, First Bank & Trust Company complements the Company’s community banking strategy by adding five communities to its banking network in Oklahoma.

On January 11, 2018, the Company acquired First Chandler Corp. and its subsidiary bank, First Bank of Chandler, with two locations in Chandler. First Bank of Chandler had approximately $88 million in total assets, $66 million in loans, $79 million in deposits and $11 million in equity capital. The bank will operate as First Bank of Chandler until it is merged into BancFirst, which is expected to be during the third quarter of 2018. As a result of the acquisition, the Company recorded a core deposit intangible of approximately $2.2 million and goodwill of approximately $6.6 million. These fair value estimates are considered preliminary and are subject to change for up to one year after the closing date of the acquisition as additional information becomes available. The effect of this acquisition was included in the consolidated financial statements of the Company from the date of acquisition forward. The acquisition did not have a material effect on the Company’s consolidated financial statements. The acquisition of First Chandler Corp. and its subsidiary bank, First Bank of Chandler complements the Company’s community banking strategy by increasing its banking network in Oklahoma.

On July 31, 2017, the Company completed a two-for-one stock split of the Company’s outstanding shares of common stock. The stock was payable in the form of a dividend on or about July 31, 2017 to shareholders of record of the outstanding common stock as of the close of business record date of July 17, 2017. Stockholders received one additional share for each share held on that date. This was the second stock split for the Company since going public. All share and per share amounts in these consolidated financial statements and related notes have been retroactively adjusted to reflect this stock split for all periods presented.

The Company’s loans are mostly to customers within Oklahoma and over 60% of the loans are secured by real estate. Credit risk on loans is managed through limits on amounts loaned to individual and related 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.

The Company’s commercial and industrial loan category includes a small percentage of loans to companies that provide ancillary services to the oil and gas industry, such as transportation, preparation contractors and equipment manufacturers. The balance of these loans was approximately $79 million at June 30, 2018 and approximately $81 million at December 31, 2017.

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, 2017.

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. During the period ended June 30, 2018 no material amount of interest income was recognized on impaired loans subsequent to their classification as impaired. During the period ended June 30, 2017, $2.3 million 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, 2017.

( 6 ) STOCK-BASED COMPENSATION

The Company adopted a nonqualified incentive stock option plan (the “BancFirst ISOP”) in May 1986. The Company has amended the BancFirst ISOP since 1986 to increase the number of shares to be issued under the plan to 6,400,000 shares. At June 30, 2018, there were 310,470 shares available for future grants. The BancFirst ISOP will terminate on December 31, 2019, if not extended. The options vest and 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, 2018 will become exercisable through the year 2025. 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 has amended the BancFirst Directors’ Stock Option Plan since 1999 to increase the number of shares to be issued under the plan to 520,000 shares. At June 30, 2018, there were 50,000 shares available for future grants. The BancFirst Directors’ Stock Option Plan will terminate on December 31, 2019, if not extended. The options vest and 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, 2018 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.

The Company currently uses newly issued shares for stock option exercises, but reserves the right to use shares 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:

		Wgtd. Avg.		Wgtd. Avg. — Remaining	Aggregate
		Exercise		Contractual	Intrinsic
Options		Price		Term	Value
(Dollars in thousands, except option data)
Six Months Ended June 30, 2018
Outstanding at December 31, 2017	1,273,625	$	25.90
Options granted	34,500		54.68
Options exercised	(99,950	)	16.45
Options canceled, forfeited, or expired	(5,000	)	48.02
Outstanding at June 30, 2018	1,203,175		27.41	9.83 Yrs	$ 38,244
Exercisable at June 30, 2018	542,925		21.17	7.32 Yrs	$ 20,648

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, — 2018	2017	Six Months Ended June 30, — 2018	2017
	(Dollars in thousands except per share data)
Weighted average grant-date fair value per share of options granted	$ 14.12	$ 10.96	$ 13.98	$ 10.96
Total intrinsic value of options exercised	967	1,032	3,827	5,645
Cash received from options exercised	411	647	1,644	3,257
Tax benefit realized from options exercised	246	399	975	2,183

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, — 2018	2017	Six Months Ended June 30, — 2018	2017
	(Dollars in thousands)
Stock-based compensation expense	$ 322	$ 243	$ 628	$ 465
Tax benefit	82	109	160	180
Stock-based compensation expense, net of tax	$ 240	$ 134	$ 468	$ 285

The Company will continue to amortize the unearned stock-based compensation expense over the remaining vesting period of approximately seven years. The following table shows the unearned stock-based compensation expense:

	June 30, 2018
	(Dollars in thousands)
Unearned stock-based compensation expense	$ 3,216

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

	Six Months Ended June 30, — 2018	2017
Risk-free interest rate	2.55 to 2.92%	2.15 to 2.38%
Dividend yield	2.00%	2.00%
Stock price volatility	23.05 to 23.29%	22.57 to 23.13%
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. The Company accounts for forfeitures as they occur.

In May 1999, the Company adopted the BancFirst Corporation Directors’ Deferred Stock Compensation Plan (the “BancFirst Deferred Stock Compensation Plan”). The Company has amended the BancFirst Deferred Stock Compensation Plan since 1999 to increase the number of shares to be issued under the plan to 222 , 220 shares. The BancFirst Deferred Stock Compensation Plan will terminate on December 31, 2019, if not extended. Under the plan, directors and members of the community advisory boards of the Company and its subsidiaries may defer up to 100% of their board fees. They are credited for each deferral with a number of stock units based on the current market price of the Company’s stock, which accumulate in an account until such time a s the director or community board member terminates serving as a board member. Shares of common stock of the Company are then distributed to the terminating director or community board member based upon the number of stock units accumulated in his or her a ccount. There were 3 ,8 91 and 9 , 918 shares of common stock distributed from the BancFirst Deferred Stock Compensation Plan during the six months ended June 30, 201 8 and June 30, 2017, respectively .

A summary of the accumulated stock units is as follows:

	June 30,	December 31,
	2018	2017
Accumulated stock units	139,114	138,768
Average price	$ 23.87	$ 22.84

(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 following table is a summary of the shares under the program:

	Six Months Ended June 30, — 2018	2017
Number of shares repurchased	—	—
Average price of shares repurchased	$ —	$ —
Shares remaining to be repurchased	300,000	300,000

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 o r 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, 201 8 , the Company and BancFirst met all capital adequacy requirements to which they a re subject. The actual and required capital amounts and ratios are shown in the following table:

			Required				To Be Well
			For Capital		With		Capitalized Under
			Adequacy		Capital Conservation		Prompt Corrective
	Actual		Purposes		Buffer		Action Provisions

As of June 30, 2018, 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

Under the Basel III Capital Rules, 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 requirements. The implementation of the capital conservation buffer began on January 1, 2016 at the 0.625% level and will be phased in over a four-year period (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, 2018, 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.

( 8 ) NET INCOME PER COMMON SHARE

Basic and diluted net income per common share based on weighted-average shares outstanding are calculated as follows:

( 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, repossessed assets, other real estate owned, 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 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 portfolio primarily 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. Periodically, the Company will validate prices supplied by the independent pricing service by comparison to prices obtained from third party sources.

Equity Securities

The Company invests in equity securities without readily determinable fair values and utilizes Level 3 inputs. Beginning January 1, 2018, upon adoption of ASU 2016-01, these securities are reported at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The realized and unrealized gains and losses are reported as securities transactions in the noninterest income section of the consolidated statements of comprehensive income. For periods prior to January 1, 2018, equity securities were classified as available-for-sale and stated at fair value with unrealized gains and losses reported as a separate component of accumulated other comprehensive income (loss), net of tax.

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.

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:

	Level 1 Inputs	Level 2 Inputs	Level 3 Inputs	Total Fair Value
	(Dollars in thousands)
June 30, 2018
Securities available for sale:
U.S. Treasury	$ 320,195	$ —	$ —	$ 320,195

Derivative assets	—	295	—	295
Derivative liabilities	—	261	—	261
Loans held for sale	—	6,173	—	6,173

The changes in Level 3 assets measured at estimated fair value on a recurring basis during the periods presented were as follows:

	Six Months Ended June 30, — 2018	2017
	(Dollars in thousands)
Balance at the beginning of the year	$ 20,171	$	21,385
Purchases	1,709		1,668
Settlements	(2,058	)	(722	)
Sales	(73	)	(5,412	)
Gains included in earnings	108		4,060
Total unrealized losses	21		(808	)
Balance at the end of the period	$ 19,878	$	20,171

The Company’s policy is to recognize transfers in and transfers out of Levels 1, 2 and 3 as of the end of the reporting period. During the six months ended June 30, 2018 and 2017, the Company did not transfer any securities between levels in the fair value hierarchy.

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.

Repossessed 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 repossessed 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. The fair value represents end of period values, which approximate fair value measurements that occurred on various measurement dates throughout the period:

	Total Fair Value
	Level 3
	(Dollars in thousands)
As of and for the Year-to-date Period Ended June 30, 2018
Impaired loans (less specific allowance)	$ 43,448
Repossessed assets	221
Other real estate owned	1,355
As of and for the Year-to-date Period Ended December 31, 2017
Impaired loans (less specific allowance)	$ 34,041
Repossessed assets	288
Other real estate owned	1,995

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

To determine the fair value of loans, the Company uses an exit price calculation, which takes into account factors such as liquidity, credit and the nonperformance risk of 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.

Short-term Borrowings

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

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:

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 periodically) 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, 2018 or December 31, 2017.

SUMMARY

BancFirst Corporation’s net income for the second quarter of 2018 was $30.6 million, compared to $23.2 million for the second quarter of 2017. Diluted net income per common share was $0.91 and $0.71 for the second quarter of 2018 and 2017, respectively.

Net income was $60.2 million, or $1.80 diluted earnings per share, for the six months ended June 30, 2018, compared to net income of $45.2 million, or $1.39 diluted earnings per share, for the six months ended June, 30, 2017. On January 11, 2018 the Company completed the acquisitions of two Oklahoma banking corporations. Consequently the six months ended June 30, 2018 included one-time acquisition related expenses of approximately $2.1 million, which reduced diluted earnings per share by approximately 5 cents in the first quarter. Net income for the six months ended June 30, 2017 included the effects of favorable resolutions of two problem loans which resulted in principal recovery of $894,000 and unaccrued interest income of $2.3 million.

The Company’s net interest income for the second quarter of 2018 increased to $64.9 million, compared to $56.4 million for the second quarter of 2017. The net interest margin for the quarter was 3.70%, compared to 3.43% a year ago. The increase in margin was primarily due to the increase in the federal funds rate throughout 2017 and 2018 and the two acquisitions in the first quarter of 2018. The Company’s provision for loan losses for the second quarter of 2018 was $1.2 million, compared to $1.8 million a year ago. Net charge-offs for the quarter were only 0.01% of average loans, compared to 0.02% for the second quarter of 2017. Noninterest income for the quarter totaled $30.4 million, compared to $28.0 million last year. Noninterest expense for the quarter totaled $54.3 million, compared to $49.0 million last year. The increase in noninterest expenses was due to salary increases in 2018 and the two acquisitions. The Company’s effective tax rate was 23.2% compared to 31.1% for the second quarter of 2017. The decrease in the effective tax rate compared to the second quarter of 2017 was due to the change in tax rates from the Tax Cuts and Jobs Act and exercising of stock options during the quarter.

At June 30, 2018, the Company’s total assets were $7.6 billion, an increase of $369.8 million from December 31, 2017. The increase in total assets was primarily related to the acquisitions during the first quarter. Securities of $462.9 million were down slightly from December 31, 2017, primarily due to Accounting Standards Update No. 2016-01, which revised securities to exclude equity investments in 2018. Loans totaled $5.0 billion, a modest increase from March 31, 2018. Loan growth for the 6 months ended June 30, 2018 was primarily from acquired loans. Deposits totaled $6.7 billion, an increase of $277.1 million from the December 31, 2017 total, which was primarily related to the acquisitions. The Company’s total stockholders’ equity was $862.0 million, an increase of $86.4 million over December 31, 2017.

Asset quality remained strong during the second quarter of 2018. Nonperforming and restructured assets were 0.67% of total assets at June 30, 2018 compared to 0.61% at December 31, 2017. The allowance to total loans was 1.04%, compared to 1.09% at year-end 2017. The allowance to nonperforming and restructured loans was 109.7% compared to 130.6% at year-end 2017.

On January 11, 2018, the Company completed the previously announced acquisitions of two Oklahoma banking corporations. First Wagoner Corporation and its subsidiary bank, First Bank & Trust Company, and First Chandler Corp. and its subsidiary bank, First Bank of Chandler, had combined total assets of approximately $378 million. The Company exchanged a combination of cash and stock for these transactions.

Net Interest Income

For the three months ended June 30, 2018, net interest income, which is the Company’s principal source of operating revenue, increased 15.0% compared to the three months ended June 30, 2017. Net interest margin, which is shown in the preceding table, is the ratio of taxable-equivalent net interest income to average earning assets for the period. The increase in the margin was primarily due to the increase in the federal funds rate throughout 2017 and 2018 and the two acquisitions in the first quarter of 2018.

Net interest income for the six months ended June 30, 2018 increased 15.0% compared to the six months ended June 30, 2017. The net interest margin for the year-to-date increased compared to the same period of the previous year, as shown in the preceding table. The increase in the margin was primarily due to the increase in the federal funds rate throughout 2017 and 2018 and the two acquisitions in the first quarter of 2018.

Provision for Loan Losses

The Company’s provision for loan loss for the second quarter of 2018 was $1.2 million compared to $1.8 million a year ago. 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 $575,000 for the second quarter of 2018, compared to $757,000 for the second quarter of 2017. The rate of net charge-offs to average total loans, as presented in the preceding table, continues to be at a very low level.

For the six months ended June 30, 2018, the Company’s provision for loan losses was $1.5 million compared to $1.9 million for the six months ended June 30, 2017. Net loan charge-offs were $1.0 million, compared to $1.6 million for the same period of the prior year.

Noninterest Income

Noninterest income totaled $30.4 million for the second quarter of 2018 compared to $28.0 million for the second quarter of 2017. Noninterest income included increases in trust revenue, insurance commissions, debit card usage fees and non-sufficient funds fees. The Company had fees from debit card usage totaling $7.4 million and $6.6 million during the three month periods ended June 30, 2018 and 2017, respectively. This represents 24.3% and 23.7% of the Company’s noninterest income for the three month periods ended June 30, 2018 and 2017, respectively. In addition, the Company has non-sufficient funds fees totaling $7.5 million and $7.0 million for the three month periods ended June 30, 2018 and 2017, respectively. This represents 24.8% and 25.1% of the Company’s noninterest income for the three month periods ended June 30, 2018 and 2017, respectively.

Noninterest income for the six months ended June 30, 2018 totaled $60.5 million compared to $56.1 million for the six months ended June 30, 2017. Noninterest income included increases in trust revenue, insurance commissions, debit card usage fees and non-sufficient funds fees. Fees from debit card usage totaled $14.2 million and $12.9 million during the six months ended June 30, 2018 and 2017, respectively. This represents 23.5% and 22.9% of the Company’s noninterest income for the six month periods ended June 30, 2018 and 2017, respectively. In addition, the Company had non-sufficient fund fees totaling $14.8 million and $13.9 million during the six months ended June 30, 2018 and 2017, respectively. This represents 24.4% and 24.8% of the Company’s noninterest income for the six month periods ended June 30, 2018 and 2017, respectively.

Noninterest Expense

For the three months ended June 30, 2018, noninterest expense totaled $54.3 million, compared to $49.0 million for the three months ended June 30, 2017. The increase in noninterest expense for the second quarter of 2018 was due to salary increases in 2018 and the two acquisitions.

For the six months ended June 30, 2018, noninterest expense totaled $110.1 million compared to $98.5 million for the six months ended June 30, 2017. The increase in noninterest expense for year-to-date 2018 was primarily due to salary increases in 2018 and the two acquisitions which included one-time acquisition related expenses of approximately $2.1 million.

Income Taxes

The Company’s effective tax rate on income before taxes was 23.2% for the second quarter of 2018, compared to 31.1% for the second quarter of 2017. The decrease in the effective tax rate was due to the change in tax rates from the Tax Cuts and Jobs Act and exercising of stock options during the period.

The Company’s effective tax rate on income before taxes was 21.6% for the first six months of 2018, compared to 32.3% for the first six months of 2017. The decrease in the effective tax rate was due to the change in tax rates from the Tax Cuts and Jobs Act and exercising of stock options during the period.

(2) Tangible book value per common share is stockholders’ equity less goodwill and intangible assets, net, divided by common shares outstanding. This amount is a non-GAAP financial measure but has been included as it is considered to be a critical metric with which to analyze and evaluate the financial condition and capital strength of the Company. This measure should not be considered a substitute for operating results determined in accordance with GAAP.

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 increased slightly by $32.3 million or 1.8% to $1.8 billion, from December 31, 2017 to June 30, 2018.

Securities

At June 30, 2018, total securities decreased $7.1 million, or 1.5% compared to December 31, 2017, primarily due to Accounting Standards Update No. 2016-01 which revised securities to exclude equity investments in 2018. The size of the Company’s securities portfolio is determined by the Company’s liquidity and asset/liability management. The net unrealized loss on securities available for sale, before taxes, was $4.9 million at June 30, 2018, compared to $3.1 million at December 31, 2017. These unrealized losses are included in the Company’s stockholders’ equity as accumulated other comprehensive income, net of income tax, in the amounts of $3.6 and $2.3 million, respectively.

Loans (Including Acquired Loans)

At June 30, 2018, loans totaled $5.0 billion, an increase of $288.9 million from December 31, 2017. Loan growth for the six months ended June 30, 2018 was primarily from acquired loans.

Allowance for Loan Losses/Fair Value Adjustments o n Acquired Loans

At June 30, 2018, the allowance for loan losses to total loans represented 1.04% of total loans, compared to 1.09% at December 31, 2017.

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 interest rate component was $2.2 million at June 30, 2018 and zero at December 31, 2017. The credit component of the adjustment was $8.8 million at June 30, 2018 and $1.2 million at December 31, 2017 while the acquired loans outstanding were $371.2 million and $120.0 million, respectively.

Nonperforming and Restructured Assets

Nonperforming and restructured assets totaled $51.4 million at June 30, 2018, compared to $44.0 million at December 31, 2017. The Company’s level of nonperforming and restructured assets has continued to be relatively low.

Nonaccrual loans totaled $30.1 million at June 30, 2018, compared to $31.9 million at the end of 2017. 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. Had nonaccrual loans performed in accordance with their original contractual terms, the Company would have recognized additional interest income of approximately $1.1 million for the six months ended June 30, 2018 and $886,000 for the six months ended June 30, 2017. Only a small amount of this interest is expected to be ultimately collected.

Restructured loans totaled $14.5 million at June 30, 2018, compared to $4.7 million at the end of 2017. The increase in restructured loans was due primarily to a few commercial loans identified as troubled debt restructurings during the period and the restructured loans from the two acquisitions. The Company charges interest on principal balances outstanding during deferral periods. As a result, the current and future financial effects of the recorded balance of loans considered to be troubled debt restructurings whose terms were modified during the period were not considered to be material.

Other real estate owned and repossessed assets totaled $3.8 million at June 30, 2018, compared to $4.4 million at December 31, 2017.

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 $7.2 million of these loans at June 30, 2018, compared to $7.7 million at December 31, 2017. 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.

Liquidity and Funding

Deposits

At June 30, 2018, deposits totaled $6.7 billion, an increase of $277.1 million from the December 31, 2017 total, which was primarily related to the acquisitions during the first quarter of 2018. 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 98.0% at June 30, 2018 compared to 98.1% at December 31, 2017. Noninterest-bearing deposits to total deposits were 39.8% at both June 30, 2018 and December 31, 2017.

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 $2.5 million at June 30, 2018, compared to $900,000 at December 31, 2017.

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 $764.8 million, are

pledged as collateral for the borrowings under the line of credit. As of June 30, 201 8 and December 31, 201 7 , the Company had no advances outstanding under the line of credit from FHLB. In addition, the Company has a revolving line of credit with another f inancial institution with the ability to draw up to $10.0 million with no advances outstanding . This line of credit has a variable rate based on prime rate minus 25 basis points and matures in 2020.

There have not been any other material changes from the liquidity 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, 2017.

Capital Resources

Stockholders’ equity totaled $862.0 million at June 30, 2018, compared to $775.6 million at December 31, 2017. In addition to net income of $60.2 million, other changes in stockholders’ equity during the three months ended June 30, 2018 included $41.2 million related to common stock issuances and $628,000 related to stock-based compensation, that were partially offset by $13.7 million in dividends and a $1.9 million decrease in other comprehensive income. The Company’s leverage ratio and total risk-based capital ratios at June 30, 2018, 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.
