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 generally accepted accounting principles and general practice within the banking industry. A summary of significant accounting policies can be found in Footnote (1) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

Basis of Presentation

The accompanying 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., BancFirst Agency, Inc., and BancFirst Community Development Corporation. 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 consolidated financial statements.

The accompanying 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, 2012, should be referred to in connection with these unaudited interim consolidated financial statements.

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, 2012, the date of the most recent annual report.

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.

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 net income.

Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-02, “Comprehensive Income (Topic 220).” ASU 2013-02 requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. An entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. The new standard was effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2012. Adoption of ASU 2013-02 did not have a significant effect on the Company’s financial statements.

In July 2012, the FASB issued ASU No. 2012-02, “Intangibles (Topic 350)—Goodwill and Other.” ASU 2012-02 simplifies the impairment test for indefinite-lived intangible assets other than goodwill. The new guidance gives the option to first assess qualitative factors to determine if it is more likely than not that the fair value of an

6

indefinite-lived intangible asset is less than its carrying amount as a basis for determining whether it is necessary to perform a quantitative valuation test. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning on or after September 15, 2012. The Company opted to continue to perform quantitative tests for indefinite-lived intangible assets other than goodwill and not to perform qualitative tests for impairment under ASU 2012-02 as of September 15, 2012. Adoption of ASU 2012-02 did not have a significant effect on the Company’s financial statements.

In November 2011, the FASB issued ASU No. 2011-11, “Balance Sheet (Topic 210)—Disclosure about Offsetting Assets and Liabilities.” ASU 2011-11 is an amendment to require an entity to disclose both net and gross information about offsetting assets and liabilities to enable users of its financial statements to understand the effect of those arrangements. Arrangements include derivatives, sale and repurchase agreements and transactions, securities borrowing and securities lending arrangements. ASU 2011-11 was effective for annual and interim periods beginning on January 1, 2013. Adoption of ASU 2011-11 did not have a significant effect on the Company’s financial statements.

(2) RECENT DEVELOPMENTS, INCLUDING MERGERS AND ACQUISITIONS

On January 19, 2012, Council Oak Investment Corporation, a wholly-owned subsidiary of BancFirst, completed the sale of one of its investments that resulted in a pretax gain of approximately $4.5 million. After related expenses and income taxes, the increase in net income approximated $2.6 million. The gain was included in first quarter 2012 earnings.

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 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 Footnote (1) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

Nonperforming and Restructured Assets

Nonaccrual loans, accruing loans past due 90 days or more, and restructured loans are shown in the table below. Had nonaccrual loans performed in accordance with their original contract terms, the Company would have recognized additional interest income of approximately $301,000 for the three months ended March 31, 2013 and approximately $338,000 for the three months ended March 31, 2012.

At March 31, 2013, troubled debt restructurings were primarily due to the principal deferral restructuring from a customer whose loan 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. Collateral value will be 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 recorded balance of loans considered to be restructured were not considered to be material.

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 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 employs several means to monitor the 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.

Loans are subject to an internal risk grading system which indicates the risk and acceptability of that loan. 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 Footnote (5) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.

(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 2,800,000 shares in May 2011. At March 31, 2013, 15,860 shares were available for future grants. The BancFirst ISOP will terminate on December 31, 2014. 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 March 31, 2013 will become exercisable through the year 2019. 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 205,000 shares in May 2009. At March 31, 2013, 30,000 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 March 31, 2013 will become exercisable through the year 2015. 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:

	Options			Wgtd. Avg. Exercise Price		Wgtd. Avg. Remaining Contractual Term			Aggregate Intrinsic Value
	(Dollars in thousands, except per share data)
Three Months Ended March 31, 2013
Outstanding at December 31, 2012		1,216,981		$	31.98
Options granted		—			—
Options exercised		(8,250	)		17.22
Options cancelled, forfeited or expired		—			—
Outstanding at March 31, 2013		1,208,731			32.08		8.43	Yrs	$	11,632
Exercisable at March 31, 2013		626,031			26.20		5.01	Yrs	$	9,703

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 March 31,
	2013		2012
	(Dollars in thousands)
Total intrinsic value of options exercised	$	348	$	1,132
Cash received from options exercised		142		483
Tax benefit realized from options exercised		135		438

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 March 31,
	2013		2012
	(Dollars in thousands)
Stock-based compensation expense	$	374	$	441
Tax		145		171
Stock-based compensation expense, net of tax	$	229	$	270

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:

	March 31, 2013
	(Dollars in thousands)
Fair value of stock options	$	5,103

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

	Three Months Ended March  31,
	2013			2012
Risk-free interest rate		1.95	%		1.95	%
Dividend yield		2.00	%		2.00	%
Stock price volatility		20.21	%		38.75	%
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 following table is a summary of the shares under the program:

	Three Months Ended March 31,
	2013		2012
Number of shares repurchased		23,050		—
Average price of shares repurchased	$	40.92		—
Shares remaining to be repurchased		211,914		241,751

The Company and BancFirst are subject to risk-based capital guidelines issued by the Board of Governors of the Federal Reserve System and 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, as of March 31, 2013, that the Company and BancFirst met all capital adequacy requirements to which they are subject. The required capital amounts and the Company’s and BancFirst’s respective ratios are shown in the following table:

15

	Actual					For Capital Adequacy Purposes					To Be Well Capitalized Under Prompt Corrective Action Provisions
	Amount		Ratio			Amount		Ratio			Amount		Ratio
	(Dollars in thousands)
As of March 31, 2013:
Total Capital
(to Risk Weighted Assets)-
BancFirst Corporation	$	531,048		14.75	%	$	288,098		8.00	%		N/A		N/A
BancFirst		502,497		13.98	%		287,481		8.00	%	$	359,351		10.00	%
Tier 1 Capital
(to Risk Weighted Assets)-
BancFirst Corporation	$	492,384		13.67	%	$	144,049		4.00	%		N/A		N/A
BancFirst		463,833		12.91	%		143,740		4.00	%	$	215,610		6.00	%
Tier 1 Capital
(to Total Assets)-
BancFirst Corporation	$	492,384		8.61	%	$	173,218		3.00	%		N/A		N/A
BancFirst		463,833		8.12	%		172,641		3.00	%	$	287,735		5.00	%

As of March 31, 2013, BancFirst was considered to be “well capitalized” and there are no conditions or events since the most recent notification of BancFirst’s capital category that management believes would materially change its category under capital requirements existing as of the report date. To be well capitalized under Federal bank regulatory agency definitions, a depository institution must have a Tier 1 Ratio of at least 6%, a combined Tier 1 and Tier 2 Ratio of at least 10%, and a Leverage Ratio of at least 5%. The Company’s trust preferred securities have continued to be included in Tier 1 capital as the Company’s total assets do not exceed $10 billion.

(8) NET INCOME PER COMMON SHARE

Basic and diluted net income per common share are calculated as follows:

	Income (Numerator)		Shares (Denominator)		Per  Share Amount
	(Dollars in thousands, except per share data)
Three Months Ended March 31, 2013
Basic
Income available to common stockholders	$	13,372		15,238,701	$	0.88
Effect of stock options		—		243,816
Diluted
Income available to common stockholders plus assumed exercises of stock options	$	13,372		15,482,517	$	0.86
Three Months Ended March 31, 2012
Basic
Income available to common stockholders	$	14,005		15,134,606	$	0.93
Effect of stock options		—		280,905
Diluted
Income available to common stockholders plus assumed exercises of stock options	$	14,005		15,415,511	$	0.91

The following table shows the number and average exercise price of options that were excluded from the computation of diluted net income per common share for each period because the options’ exercise prices were greater than the average market price of the common shares:

16

	Shares		Average Exercise Price
Three Months Ended March 31, 2013		534,000	$	39.44
Three Months Ended March 31, 2012		607,200	$	38.70

(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 Accounting Standards Codification 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, 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 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 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.

17

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.

Mortgage Servicing Intangibles

The Company acquired these Mortgage Servicing Intangibles with the acquisition of 1^st Bank Oklahoma on July 12, 2011. Mortgage Servicing Intangibles are amortized based on current prepayment assumptions and are adjusted to fair value quarterly, 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 March 31, 2013 and 2012, 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

The changes in Level 3 assets measured at estimated fair value on a recurring basis during the three months ended March 31, 2013 and 2012 were as follows:

	Three Months Ended March 31,
	2013			2012
	(Dollars in thousands)
Balance at the beginning of the year	$	10,779		$	13,225

Total unrealized losses		(17	)		(2,066	)
Balance at the end of the period	$	10,833		$	10,377

18

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 three months ended March 31, 2013 and 2012, 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. The impaired loans are adjusted to fair value through a specific allocation of the allowance for loan losses.

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 gains or losses recognized during the period:

	Level 1		Level 2		Level 3		Total Fair Value		Gains (Losses)
	(Dollars in thousands)
Three Months Ended March 31, 2013
Impaired loans (less specific allowance)		—		—	$	40,852	$	40,852	$	—

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.

19

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.

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 are as follows:

	March 31,

	(Dollars in thousands)

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 quarterly) 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 were not considered to be significant to the Company at March 31, 2013 or 2012.

(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.

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

	March 31, 2013
Oil and Natural Gas Swaps and Options	Notional Units	Notional Amount			Estimated Fair  Value
	(Notional amounts and dollars in thousands)

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 March 31,
	2013		2012
	(Dollars in thousands)
Derivative income	$	108	$	209

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.

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:

The Company entered into a $30 million five year guaranty with a counterparty on June 4, 2008 for the timely payment of the obligations of its subsidiary Bank related to the settlement of oil and gas positions.

(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 four principal business units are metropolitan banks, community banks, other financial services, and executive, operations and support. Metropolitan and community banks offer traditional banking products such as commercial and retail lending, and a full line of deposit accounts. Metropolitan banks consist of banking locations in the metropolitan Oklahoma City and Tulsa areas. Community banks consist of banking locations in communities throughout Oklahoma. Other financial services are specialty product business units including guaranteed small business lending, residential mortgage lending, trust services, securities brokerage, electronic banking and insurance. The executive, operations and support groups represent executive management, operational support and corporate functions that are not allocated to the other business units.

SUMMARY

BancFirst Corporation’s net income for the first quarter of 2013 was $13.4 million compared to $14.0 million for the first quarter of 2012. Diluted net income per share was $0.86 and $0.91 for the first quarter of 2013 and 2012, respectively. Included in the 2012 quarter’s net income was a $4.5 million securities gain that was partially offset by merger related expenses and other non-operating costs totaling $2.5 million. Excluding these items, the Company’s net income for the first quarter of 2012 would have been approximately $12.7 million, or approximately $0.83 diluted net income per share.

Net interest income for the first quarter of 2013 was $40.3 million compared to $40.8 million for the first quarter of 2012. The Company’s net interest margin for the quarter was 3.08% compared to 3.18% a year ago, as interest rates have remained at historically low levels. The Company’s provision for loan loss for the first quarter of 2013 was $300,000 compared to $173,000 for the first quarter of 2012. Net charge-offs for the quarter were only 0.01% of average loans, which was the same as for the first quarter of 2012. Noninterest income for the quarter totaled $22.5 million, compared to $23.4 million last year. Noninterest expense for the quarter totaled $41.9 million compared to $42.0 million last year.

At March 31, 2013, the Company’s total assets were $5.8 billion, down $248.3 million, or 4.1%, from $6.0 billion at December 31, 2012. Loans totaled $3.2 billion, down $22.5 million from December 31, 2012. Deposits totaled $5.2 billion, down $266.3 million due to a temporary influx of deposits at year end 2012. Stockholders’ equity was $527.7 million, an increase of $8.1 million, or 1.6%, over December 31, 2012.

Asset quality remained strong and was little changed from the previous quarters. Nonperforming and restructured assets were 0.84% of total assets compared to 0.81% at December 31, 2012. The allowance to total loans was 1.20% compared to 1.19% at year end 2012.

Net Interest Income

For the three months ended March 31, 2013, net interest income, which is the Company’s principal source of operating revenue, was $40.3 million compared to $40.8 million for the three months ended March 31, 2012. 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 decreased for the three months ended March 31, 2013 compared to the three months ended March 31, 2012, as shown in the preceding table, which was due to continued low interest rates and the maturity or pay down of higher-yielding earning assets. If interest rates and/or loan volume do not increase, management expects continued compression of its net interest margin for the remainder of 2013 as higher yielding loans and securities mature and are replaced at current market rates.

Provision for Loan Losses

For the three months ended March 31, 2013, the Company’s provision for loan losses was $300,000, compared to $173,000 for the same period a year ago. Management believes the recorded amount of 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 level of future provisions for loan losses. Net loan charge-offs were $361,000 for the first quarter of 2013 compared to $196,000 for the first quarter of 2012. The rate of net charge-offs to average total loans is presented in the preceding table.

Noninterest Income

Noninterest income totaled $22.5 million for the three months ended March 31, 2013 compared to $23.4 million for the three months ended March 31, 2012. The first quarter of 2012 included a $4.5 million pretax securities gain from the sale of an investment by the Company’s Small Business Investment Corporation, Council Oak Investment Corporation, a wholly-owned subsidiary of BancFirst.

24

The Company had income from debit card usage totaling $4.1 million during the three months ended March 31, 2013 and 2012. The Dodd-Frank Act has given the Federal Reserve the authority to establish rules regarding debit card interchange fees charged for electronic debit transactions by payment card issuers. Because of the uncertainty as to any future rulemaking by the Federal Reserve and the inability to forecast competitive responses, the Company cannot provide any assurance as to the ultimate impact of the Dodd-Frank Act on the amount of revenue from debit card usage reported in future periods.

Noninterest Expense

For the three months ended March 31, 2013, noninterest expense totaled $41.9 million compared to $42.0 million for the three months ended March 31, 2012. Included in the 2012 quarter’s noninterest expense is $1.6 million in merger related costs and approximately $500,000 of expenses related to the sale of an investment by the Company’s Small Business Investment Corporation, Council Oak Investment Corporation, a wholly-owned subsidiary of BancFirst.

Income Taxes

The Company’s effective tax rate on income before taxes was 34.9% for the first quarter of 2013 compared to 36.5% for the first quarter of 2012 due primarily to new tax credits utilized.

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 March 31, 2013 decreased $229.8 million from December 31, 2012 and $120.9 million from March 31, 2012. The higher level at year-end 2012 was due primarily to funds provided by the temporary influx of deposits at year-end 2012. 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.

25

Securities

At March 31, 2013, total securities increased $2.9 million compared to December 31, 2012 and decreased $8.3 million compared to March 31, 2012. 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 $9.1 million at March 31, 2013, compared to an unrealized gain of $9.7 million at December 31, 2012 and $11.6 million at March 31, 2012. These unrealized gains are included in the Company’s stockholders’ equity as accumulated other comprehensive income, net of income tax, in the amounts of $5.9 million, $6.3 million and $7.5 million, respectively.

Loans (Including Acquired Loans)

At March 31, 2013, total loans were down $22.5 million from December 31, 2012 and up $170.6 million from March 31, 2012 due primarily to growth in the fourth quarter of 2012.

Allowance for Loan Losses/Fair Value Adjustments on Acquired Loans

At March 31, 2013, the allowance for loan losses represented 1.20% of total loans, compared to 1.19% at December 31, 2012 and 1.23% at March 31, 2012. The allowance for loan losses as a percentage of total loans and the allowance to nonperforming and restructured loans are shown in the preceding table.

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 $2.7 million at March 31, 2013, $2.8 million at December 31, 2012 and $3.8 million at March 31, 2012, while the acquired loans outstanding were $96.2 million, $108.5 million and $162.6 million, respectively. The decrease from the first quarter of 2012 was due t improved credit quality of the loans, loan payoffs and the early settlement of a loan escrow agreement related to one of the bank acquisitions.

Nonperforming and Restructured Assets

Nonperforming and restructured assets totaled $48.7 million at March 31, 2013 compared to $48.5 million at December 31, 2012 and $52.8 million at March 31, 2012. The Company’s level of nonperforming and restructured assets has continued to be relatively low, as shown in the preceding table.

Nonaccrual loans totaled $20.9 million at March 31, 2013 compared to $20.5 million at the end of 2012. 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 for the quarter, which was not accrued on nonaccrual loans outstanding was approximately $301,000 at March 31, 2013 and $338,000 at March 31, 2012. Only a small amount of this interest is expected to be ultimately collected.

Other real estate owned and repossessed assets totaled $9.4 million at March 31, 2013 compared to $9.6 million at December 31, 2012 and $12.4 million at March 31, 2012. The decrease in 2012 was due in part to the sale of one nonperforming commercial real estate property valued at $3.5 million.

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 $3.3 million of these loans at March 31, 2013 compared to $5.3 million at December 31, 2012 and $7.3 million at March 31, 2012. These 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 March 31, 2013, total deposits decreased $266.3 million compared to December 31, 2012 and increased $21.7 million compared to March 31, 2012. The decrease from December 31, 2012 was due to a temporary influx of deposits at year end 2012. 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 92.8% at March 31, 2013and December 31, 2012 compared to 92.3% at March 31, 2012. Noninterest-bearing deposits to total deposits were 37.4% at March 31, 2013, compared to 37.1% at December 31, 2012 and 35.3% at March 31, 2012.

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 $4.9 million at March 31, 2013 compared to $4.6 million at December 31, 2012 and $7.3 million at March 31, 2012.

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 $535.9 million, are pledged as collateral for the borrowings under the line of credit. As of March 31, 2013, the Company had approximately $11.0 million in advances outstanding compared to $9.2 million at December 31, 2012 and $13.4 million at March 31, 2012. The advances mature at varying dates through 2014.

There have not been 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, 2012.

Capital Resources

Stockholders’ equity totaled $527.7 million at March 31, 2013 compared to $519.6 million at December 31, 2012 and $492.0 million at March 31, 2012. In addition to net income of $13.4 million, other changes in stockholders’ equity during the three months ended March 31, 2013 included $190,000 related to stock option exercises and $374,000 related to stock-based compensation, that were partially offset by $4.4 million in dividends, $943,000 in common stock acquired and canceled, and a $431,000 decrease in other comprehensive income. The Company’s average stockholders’ equity to average assets are presented above. The Company’s leverage ratio and total risk-based capital ratio were 8.61% and 14.75%, respectively, at March 31, 2013, well in excess of the regulatory minimums.

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, 2012.
