	Note 1:  Basis of Presentation
	The accompanying unaudited consolidated interim financial statements of First Busey Corporation (“First Busey” or the “Company”), a Nevada corporation, have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for Quarterly Reports on Form 10-Q and do not include certain information and footnote disclosures required by U.S. generally accepted accounting principles (“GAAP”) for complete annual financial statements. Accordingly, these financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
	The accompanying Consolidated Balance Sheets as of December 31, 2013, which have been derived from audited financial statements, and the unaudited consolidated interim financial statements have been prepared in accordance with GAAP and reflect all adjustments that are, in the opinion of management, necessary for the fair presentation of the financial position and results of operations as of the dates and for the periods presented. All such adjustments are of a normal recurring nature. The results of operations for the three and nine months ended September 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014.
	The consolidated financial statements include the accounts of the Company and its subsidiaries. All material intercompany transactions and balances have been eliminated in consolidation. Certain prior-year amounts have been reclassified to conform to the current presentation with no effect on net income or stockholders’ equity.
	In preparing the accompanying consolidated financial statements, the Company’s management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses for the reporting period.  Actual results could differ from those estimates.  Material estimates which are particularly susceptible to significant change in the near term relate to the fair value of investment securities, the determination of the allowance for loan losses, and the valuation allowance on the deferred tax asset.
	The Company has evaluated subsequent events for potential recognition and/or disclosure through the date the consolidated financial statements included in this Quarterly Report on Form 10-Q were issued.  Other than the return of capital and associated surplus to the Company from Busey Bank (the “Bank”), which was executed on October 22, 2014, as discussed in the capital resources section of management’s discussion and analysis of financial condition and results of operations, there were no significant subsequent events for the quarter ended September 30, 2014 through the issuance date of these financial statements that warranted adjustment to or disclosure in the consolidated financial statements.

	ASU 2014-04, “Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40) - Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure.” ASU 2014-04 clarifies when an in-substance repossession or foreclosure occurs and requires interim and annual disclosures.  The new authoritative guidance will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2014 and is not expected to have a significant impact on the Company’s financial statements.
	ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).”  ASU 2014-09 outlines a single model for companies to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 will require that companies recognize revenue based on the value of transferred goods or services as they occur in the contract and will also require additional disclosures.  The new authoritative guidance will be for reporting periods after December 15, 2016, and the Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures.
	ASU 2014-14, “Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40) — Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure.” ASU 2014-14 requires that certain government-guaranteed mortgage loans be derecognized and that a separate other receivable be recognized upon foreclosure if certain conditions are met. Upon foreclosure on loans that meet these criteria, a separate receivable should be recorded based on the amount of the loan balance expected to be recovered from the guarantor. The new authoritative guidance will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2014 and is not expected to have a significant impact on the Company’s financial statements.

	Note 3:  Securities
	Securities are classified as held to maturity when First Busey has the ability and management has the positive intent to hold those securities to maturity.  Accordingly, they are stated at cost, adjusted for amortization of premiums and accretion of discounts.  Securities are classified as available for sale when First Busey may decide to sell those securities due to changes in market interest rates, liquidity needs, changes in yields on alternative investments, and for other reasons.  They are carried at fair value with unrealized gains and losses, net of taxes, reported in other comprehensive income.

Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation.  Consideration is given to the length of time and extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, and whether the Company has the intent to sell the security and it is more-likely-than-not it will have to sell the security before recovery of its cost basis.
The total number of securities in the investment portfolio in an unrealized loss position as of September 30, 2014 was 158, and represented a loss of 0.7% of the aggregate carrying value. Based upon a review of unrealized loss circumstances, the unrealized losses resulted from changes in market interest rates and liquidity, not from changes in the probability of receiving the contractual cash flows. The Company does not intend to sell the securities and it is more-likely-than-not that the Company will recover the amortized cost prior to being required to sell the securities.  Full collection of the amounts due according to the contractual terms of the securities is expected; therefore, the Company does not consider these investments to be other-than-temporarily impaired at September 30, 2014.
The Company had available for sale obligations of state and political subdivisions with a fair value of $237.2 million and $272.2 million as of September 30, 2014 and December 31, 2013, respectively.  In addition, the Company had held to maturity obligations of state and political subdivisions totaling $1.4 million and $0.8 million at September 30, 2014 and December 31, 2013, respectively.
As of September 30, 2014, the Company’s obligations of state and political subdivisions portfolio was comprised of $196.7 million of general obligation bonds and $41.8 million of revenue bonds issued by 238 issuers, primarily consisting of states, counties, cities, towns, villages and school districts.  The Company held investments in general obligation bonds in 23 states (including the District of Columbia), including seven states in which the aggregate fair value exceeded $5.0 million.  The Company held investments in revenue bonds in 17 states, including two states where the aggregate fair value exceeded $5.0 million.
As of December 31, 2013, the Company’s obligations of state and political subdivisions portfolio was comprised of $223.5 million of general obligation bonds and $49.5 million of revenue bonds issued by 267 issuers, primarily consisting of states, counties, cities, towns, villages and school districts.  The Company held investments in general obligation bonds in 25 states (including the District of Columbia), including seven states in which the aggregate fair value exceeded $5.0 million.  The Company held investments in revenue bonds in 21 states, including two states where the aggregate fair value exceeded $5.0 million.

The general obligation bonds are diversified across many issuers, with $3.5 million and $5.0 million being the largest exposure to a single issuer at September 30, 2014 and December 31, 2013, respectively.  Accordingly, as of September 30, 2014 and December 31, 2013, the Company did not hold general obligation bonds of any single issuer, the aggregate book or market value of which exceeded 10% of the Company’s stockholders’ equity. Of the general obligation bonds in the Company’s portfolio, 96.9% had been rated by at least one nationally recognized statistical rating organization and 3.1% were unrated, based on the fair value as of September 30, 2014.  Of the general obligation bonds in the Company’s portfolio, 96.4% had been rated by at least one nationally recognized statistical rating organization and 3.6% were unrated, based on the fair value as of December 31, 2013.
The amortized cost and fair values of the Company’s portfolio of revenue bonds are summarized in the following tables by the issuers’ state:

The revenue bonds are diversified across many issuers and revenue sources with $3.0 million being the largest exposure to a single issuer at each of September 30, 2014 and December 31, 2013.  Accordingly, as of September 30, 2014 and December 31, 2013, the Company did not hold revenue bonds of any single issuer, the aggregate book or market value of which exceeded 10% of the Company’s stockholders’ equity.  All of the revenue bonds in the Company’s portfolio had been rated by at least one nationally recognized statistical rating organization as of September 30, 2014 and December 31, 2013.  Some of the primary types of revenue bonds owned in the Company’s portfolio include: primary education or government building lease rentals secured by ad valorem taxes, utility systems secured by utility system net revenues, housing authorities secured by mortgage loans or principal receipts on mortgage loans, secondary education secured by student fees/tuitions, and pooled issuances (i.e. bond bank) consisting of multiple underlying municipal obligors.
Substantially all of the Company’s obligations of state and political subdivision securities are owned by Busey Bank, whose investment policy requires that state and political subdivision securities purchased be investment grade.  Busey Bank’s investment policy also limits the amount of rated state and political subdivision securities to an aggregate 100% of the Bank’s Total Risk Based Capital at the time of purchase and an aggregate 15% of Total Risk Based Capital for unrated state and political subdivision securities issued by municipalities having taxing authority or located in counties/micropolitan statistical areas/metropolitan statistical areas in which an office of the Bank is located.  The investment policy states fixed income investments that are not Office of the Comptroller of the Currency Type 1 securities (U.S. Treasuries, agencies, municipal government general obligation and, for well-capitalized institutions, most municipal revenue bonds) should be analyzed prior to acquisition to determine that (1) the security has low risk of default by the obligor, and (2) the full and timely repayment of principal and interest is expected over the expected life of the investment.  All securities in the Bank’s obligations of state and political subdivision securities portfolio are subject to ongoing review.  Factors that may be considered as part of ongoing monitoring of state and political subdivision securities include credit rating changes by nationally recognized statistical rating organizations, market valuations, third-party municipal credit analysis, which may include indicative information regarding the issuer’s capacity to pay, market and economic data and such other factors as are available and relevant to the security or the issuer such as its budgetary position and sources, strength and stability of taxes and/or other revenue.
As of September 30, 2014, the Company’s regular monitoring of its obligations of state and political subdivisions portfolio had not uncovered any facts or circumstances resulting in significantly different credit ratings than those assigned by a nationally recognized statistical rating organization.

	The Company believes that sound loans are a necessary and desirable means of employing funds available for investment. Recognizing the Company’s obligations to its stockholders, depositors, and to the communities it serves, authorized personnel are expected to seek to develop and make sound, profitable loans that resources permit and that opportunity affords. The Company maintains lending policies and procedures designed to focus lending efforts on the types, locations and duration of loans most appropriate for its business model and markets.  While not specifically limited, the Company attempts to focus its lending on short to intermediate-term (0-7 years) loans in geographies within 125 miles of its lending offices.  The Company attempts to utilize government-assisted lending programs, such as the Small Business Administration and United States Department of Agriculture lending programs, when prudent. Generally, loans are collateralized by assets, primarily real estate, of the borrowers and guaranteed by individuals.  The loans are expected to be repaid primarily from cash flows of the borrowers, or from proceeds from the sale of selected assets of the borrowers.
	Management reviews and approves the Company’s lending policies and procedures on a routine basis.  Management routinely (at least quarterly) reviews the Company’s allowance for loan losses and reports related to loan production, loan quality, concentrations of credit, loan delinquencies and non-performing and potential problem loans. The Company’s underwriting standards are designed to encourage relationship banking rather than transactional banking.  Relationship banking implies a primary banking relationship with the borrower that includes, at a minimum, an active deposit banking relationship in addition to the lending relationship.  The integrity and character of the borrower are significant factors in the Company’s loan underwriting.  As a part of underwriting, tangible positive or negative evidence of the borrower’s integrity and character are sought out.  Additional significant underwriting factors beyond location, duration, a sound and profitable cash flow basis and the borrower’s character are the quality of the borrower’s financial history, the liquidity of the underlying collateral and the reliability of the valuation of the underlying collateral.
	Total borrowing relationships, including direct and indirect debt, are generally limited to $20 million, which is significantly less than the Company’s regulatory lending limit.  Borrowing relationships exceeding $20 million are reviewed by the Company’s board of directors at least annually and more frequently by management.  At no time is a borrower’s total borrowing relationship permitted to exceed the Company’s regulatory lending limit.  Loans to related parties, including executive officers and the Company’s various directorates, are reviewed for compliance with regulatory guidelines by the Company’s board of directors at least annually.
	The Company maintains an independent loan review department that reviews the loans for compliance with the Company’s loan policy on a periodic basis.  In addition to compliance with this policy, the loan review process reviews the risk assessments made by the Company’s credit department, lenders and loan committees. Results of these reviews are presented to management and the audit committee at least quarterly.
	The Company’s lending can be summarized into five primary areas: commercial loans, commercial real estate loans, real estate construction loans, retail real estate loans, and other retail loans. A description of each of the lending areas can be found in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.  The significant majority of the lending activity occurs in the Company’s Illinois and Indiana markets, with the remainder in the Florida market.  Due to the small scale of the Indiana loan portfolio and its geographical proximity to the Illinois portfolio, the Company believes that quantitative or qualitative segregation between Illinois and Indiana is not material or warranted.
	The Company utilizes a loan grading scale to assign a risk grade to all of its loans.  Loans are graded on a scale of 1 through 10 with grades 2, 4 & 5 unused.  A description of the general characteristics of the grades is as follows:
	·         Grades 1, 3, 6- These grades include loans which are all considered strong credits, with grade 1 being investment or near investment grade.  A grade 3 loan is comprised of borrowers that exhibit credit fundamentals that exceed industry standards and loan policy guidelines. A grade 6 loan is comprised of borrowers that exhibit acceptable credit fundamentals.
	·         Grade 7- This grade includes loans on management’s “Watch List” and is intended to be utilized on a temporary basis for a pass grade borrower where a significant risk-modifying action is anticipated in the near future.
	·         Grade 8- This grade is for “Other Assets Specially Mentioned” loans that have potential weaknesses which may, if not checked or corrected, weaken the asset or inadequately protect the Company’s credit position at some future date.
	·         Grade 9- This grade includes “Substandard” loans, in accordance with regulatory guidelines, for which the accrual of interest has not been stopped.  Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt.  They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.
	·         Grade 10- This grade includes “Doubtful” loans that have all the characteristics of a substandard loan with additional factors that make collection in full highly questionable and improbable. Such loans are placed on non-accrual status and may be dependent on collateral having a value that is difficult to determine.
	All loans are graded at the inception of the loan.  All commercial loans that are $1.0 million or less are processed through an expedited underwriting process.  If the credit receives a pass grade it is aggregated into a homogenous pool of either:  $0.35 million or less or $0.35 million to $1.0 million.  These pools are monitored on a quarterly basis for the first year, semiannually in the second year and annually thereafter.  Homogenous pool credits which are subsequently downgraded to a grading of 7 or worse, are subject to the same portfolio review as loans over $1.0 million.  All commercial loans greater than $1.0 million dollars receive a portfolio review at least annually.  Commercial loans greater than $1.0 million that have a grading of 7 receive a portfolio review twice per year.  Commercial loans greater than $1.0 million that have a grading of 8 or worse receive a portfolio review on a quarterly basis.  Interim grade reviews may take place if circumstances of the borrower warrant a more timely review.
	Loans in the highest grades, represented by grades 1, 3, 6 and 7, totaled $2.2 billion at September 30, 2014 compared to $2.1 billion at December 31, 2013.  Loans in the lowest grades, represented by grades 8, 9 and 10, totaled $131.8 million at September 30, 2014, a decline of $30.1 million from $161.9 million at December 31, 2013.
	The following table presents weighted average risk grades segregated by category of loans (excluding held for sale, non-posted and clearings) and geography:

Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due.  Loans are placed on non-accrual status when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory provisions.  Loans may be placed on non-accrual status regardless of whether or not such loans are considered past due.  When interest accrual is discontinued, all unpaid accrued interest is reversed.  Interest income is subsequently recognized only to the extent cash payments are received in excess of the principal due.  Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
An age analysis of past due loans still accruing and non-accrual loans is as follows:

A loan is impaired when, based on current information and events, it is probable the Company will be unable to collect scheduled principal and interest payments when due according to the terms of the loan agreement.  Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due.  Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired.  Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed.  The following loans are assessed for impairment by the Company: loans 60 days or more past due and over $0.25 million, loans graded 8 over $0.5 million and loans graded 9 or 10.
Impairment is measured on a loan-by-loan basis for commercial and construction loans by either the present value of the expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent.  Large groups of smaller balance homogenous loans are collectively evaluated for impairment.  Accordingly, the Company does not separately identify individual consumer and residential loans for impairment disclosures unless such loans are the subject of a restructuring agreement.
The gross interest income that would have been recorded in the three and nine months ended September 30, 2014 if impaired loans had been current in accordance with their original terms was $0.1 million and $0.7 million, respectively.  The amount of interest collected on those loans and recognized on a cash basis that was included in interest income was insignificant for the three and nine months ended September 30, 2014.
The Company’s loan portfolio includes certain loans that have been modified in a troubled debt restructuring (“TDR”), where concessions have been granted to borrowers who have experienced financial difficulties. The Company will restructure loans for its customers who appear to be able to meet the terms of their loan over the long term, but who may be unable to meet the terms of the loan in the near term due to individual circumstances.
The Company considers the customer’s past performance, previous and current credit history, the individual circumstances surrounding the current difficulties and the customer’s plan to meet the terms of the loan in the future prior to restructuring the terms of the loan.  Generally, all five primary areas of lending are restructured through short-term interest rate relief, short-term principal payment relief, short-term principal and interest payment relief, or forbearance (debt forgiveness).  Once a restructured loan has gone 90+ days past due or is placed on non-accrual status, it is included in the non-performing loan totals. A summary of restructured loans as of September 30, 2014 and December 31, 2013 is as follows:
	September 30, 2014			December 31, 2013
	(dollars in thousands)
Restructured loans:
In compliance with modified terms	$	11,050		$	11,511
30 – 89 days past due	—			380
Included in non-performing loans	2,253			5,919
Total	$	13,303		$	17,810
All TDRs are considered to be impaired for purposes of assessing the adequacy of the allowance for loan losses and for financial reporting purposes.  When the Company modifies a loan in a TDR, it evaluates any possible impairment similar to other impaired loans based on present value of the expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent.  If the Company determines that the value of the TDR is less than the recorded investment in the loan, impairment is recognized through an allowance estimate in the period of the modification and in periods subsequent to the modification.
There were no performing loans classified as TDRs during the three months ended September 30, 2014.  Performing loans classified as TDRs during the nine months ended September 30, 2014 were insignificant.
Performing loans classified as TDRs during the three and nine months ended September 30, 2013 included one commercial real estate modification in Illinois/Indiana for short-term principal payment relief, with a recorded investment of $0.2 million.  Performing loans classified as TDRs during the nine months ended September 30, 2013 also included one commercial real estate modification in Florida for short-term interest rate relief, with a recorded investment of $0.1 million.
The gross interest income that would have been recorded in the three and nine months ended September 30, 2014 and 2013 if performing TDRs had been in accordance with their original terms instead of modified terms was insignificant.
There were no TDRs that were classified as non-performing and had payment defaults (a default occurs when a loan is 90 days or more past due or transferred to non-accrual) during the three and nine months ended September 30, 2014.
TDRs that were classified as non-performing and had payment defaults during the three months ended September 30, 2013 consisted of one Florida retail real estate modification totaling $0.1 million.  TDRs that were classified as non-performing and had payment defaults during the nine months ended September 30, 2013 consisted of one Illinois/Indiana commercial real estate modification totaling $1.7 million, one Illinois/Indiana real estate construction modification totaling $0.3 million, four Illinois/Indiana retail real estate modifications totaling $1.1 million and two Florida retail real estate modifications totaling $0.2 million.
The following tables provide details of impaired loans, segregated by category and geography. The unpaid contractual principal balance represents the recorded balance prior to any partial charge-offs.  The recorded investment represents customer balances net of any partial charge-offs recognized on the loan.  The average recorded investment is calculated using the most recent four quarters.

Management’s opinion as to the ultimate collectability of loans is subject to estimates regarding future cash flows from operations and the value of property, real and personal, pledged as collateral.  These estimates are affected by changing economic conditions and the economic prospects of borrowers.
Allowance for Loan Losses
The allowance for loan losses represents an estimate of the amount of losses believed inherent in the Company’s loan portfolio at the balance sheet date.  The allowance for loan losses is evaluated geographically, by class of loans.  The allowance calculation involves a high degree of estimation that management attempts to mitigate through the use of objective historical data where available. Loan losses are charged against the allowance for loan losses when management believes the uncollectibility of the loan balance is confirmed.  Subsequent recoveries, if any, are credited to the allowance.  Overall, the Company believes the allowance methodology is consistent with prior periods and the balance was adequate to cover the estimated losses in the Company’s loan portfolio at September 30, 2014 and December 31, 2013.
The general portion of the Company’s allowance contains two components: (i) a component for historical loss ratios, and (ii) a component for adversely graded loans.  The historical loss ratio component is an annualized loss rate calculated using a sum-of-years digits weighted 20-quarter historical average.
The Company’s component for adversely graded loans attempts to quantify the additional risk of loss inherent in the grade 8 and grade 9 portfolios.  The grade 9 portfolio has an additional allocation placed on those loans determined by a one-year charge-off percentage for the respective loan type/geography.  The minimum additional reserve on a grade 9 loan was 3.00% as of each of September 30, 2014 and December 31, 2013, which is an estimate of the additional loss inherent in these loan grades based upon a review of overall historical charge-offs.  As of September 30, 2014, the Company believed this minimum reserve remained adequate.
Grade 8 loans have an additional allocation placed on them determined by the trend difference of the respective loan type/geography’s rolling 12- and 20-quarter historical loss trends. If the rolling 12-quarter average is higher (more current information) than the rolling 20-quarter average, the Company adds the additional amount to the allocation.  The minimum additional amount for grade 8 loans was 1.00% as of September 30, 2014 and December 31, 2013, based upon a review of the differences between the rolling 12- and 20-quarter historical loss averages by region.  As of September 30, 2014, the Company believed this minimum additional amount remained adequate.
The specific portion of the Company’s allowance relates to loans that are impaired, which includes non-performing loans, TDRs and other loans determined to be impaired.  The impaired loans are subtracted from the general loans and are allocated specific reserves as discussed above.
Impaired loans are reported at the fair value of the underlying collateral, less estimated costs to sell, if repayment is expected solely from the collateral. Collateral values are estimated using a combination of observable inputs, including recent appraisals discounted for collateral specific changes and current market conditions, and unobservable inputs based on customized discounting criteria.
The general quantitative allocation based upon historical charge off rates is adjusted for qualitative factors based on current general economic conditions and other qualitative risk factors both internal and external to the Company. In general, such valuation allowances are determined by evaluating, among other things:  (i) Management & Staff; (ii) Loan Underwriting, Policy and Procedures; (iii) Internal/External Audit & Loan Review; (iv) Valuation of Underlying Collateral; (v) Macro and Local Economic Factor; (vi) Impact of Competition, Legal & Regulatory Issues; (vii) Nature and Volume of Loan Portfolio; (viii) Concentrations of Credit; (ix) Net Charge-Off Trend; and (x) Non-Accrual, Past Due and Classified Trend.  Management evaluates the degree of risk that each one of these components has on the quality of the loan portfolio on a quarterly basis.  Based on each component’s risk factor, a qualitative adjustment to the reserve may be applied to the appropriate loan categories.
During the third quarter of 2014, the Company adjusted Illinois/Indiana qualitative factors relating to Loan Underwriting, Policy and Procedures, Macro and Local Economic Factor, Nature and Volume of Loan Portfolio, and Net Charge-Off Trend.  Additionally, the Company adjusted Florida qualitative factors relating to Loan Underwriting, Policy and Procedures, Macro and Local Economic Factor, and Net Charge-Off Trend.  The adjustment of these factors increased our allowance requirements by $5.3 million at September 30, 2014 compared to the method used for June 30, 2014.  Further, during the first quarter of 2014, the Company adjusted Illinois/Indiana and Florida qualitative factors relating to Net Charge-Off Trend compared to the method used for December 31, 2013.  Adjustments to increase these qualitative factors were made in the third and first quarters of 2014 to recognize perceived changing degrees of risk, offset decreasing quantitative factors and reflect management’s evaluation of risk.  The Company will continue to monitor its qualitative factors on a quarterly basis.
The following table details activity on the allowance for loan losses.  Allocation of a portion of the allowance to one category does not preclude its availability to absorb losses in other categories.

	Basic earnings per share are computed by dividing net income available to common stockholders for the period by the weighted average number of common shares outstanding.
	Diluted earnings per common share is computed using the treasury stock method and reflects the potential dilution that could occur if the Company’s outstanding stock options were exercised and restricted stock units were vested.  Stock options and restricted stock units for which the exercise or the grant price exceeds the average market price over the period have an anti-dilutive effect and are excluded from the calculation.  At September 30, 2014, 457,630 outstanding options, 573,833 warrants, and 353,976 restricted stock units were anti-dilutive and excluded from the calculation of common stock equivalents.  At September 30, 2013, 648,529 outstanding options, 573,833 warrants, and 380,252 restricted stock units were anti-dilutive and excluded from the calculation of common stock equivalents.

Stock-based Compensation	'
	Note 7:  Stock-based Compensation
	The Company grants share-based compensation awards to its employees and members of its board of directors as provided for under the Company’s 2010 Equity Incentive Plan. The Company currently grants share-based compensation in the form of restricted stock units (“RSUs”) and deferred stock units (“DSUs”).  The Company also has outstanding stock options granted prior to 2011.  Under the terms of the Company’s 2010 Equity Incentive Plan, the Company is allowed, but not required, to source stock option exercises and grants of RSUs and DSUs from its inventory of treasury stock.  As of September 30, 2014, the Company held 1,442,257 shares in treasury, with 895,655 additional shares authorized for repurchase under its stock repurchase plan.  The repurchase plan has no expiration date and expires when the Company has repurchased all of the remaining authorized shares.
	A description of the 2010 Equity Incentive Plan can be found in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.  The Company’s 2010 Equity Incentive Plan is designed to encourage ownership of its common stock by its employees and directors, to provide additional incentive for them to promote the success of its business, and to attract and retain talented personnel.  All of the Company’s employees and directors, and those of its subsidiaries, are eligible to receive awards under the plan.
	A summary of the status of and changes in the Company’s stock option awards for the nine months ended September 30, 2014 follows:
				Weighted-			Weighted-

	Outstanding at end of period	1,184,558		144,822		1,329,380		$	5.22
	All recipients earn quarterly dividend equivalents on their respective units. These dividend equivalents are not paid out during the vesting period, but instead entitle the recipients to additional units. Therefore, dividends earned each quarter compound based upon the updated unit balances.  Upon vesting/delivery, shares are expected to be issued from treasury.
	On June 23, 2014, under the terms of the 2010 Equity Incentive Plan, the Company granted 304,277 RSUs to members of management.  As the stock price on the grant date of June 23, 2014 was $5.84, total compensation cost to be recognized is $1.8 million.  This cost will be recognized over a period of two to five years.   Subsequent to each requisite service period, the awards will vest 100%.
	Additionally, on June 23, 2014, under the terms of the 2010 Equity Incentive Plan, the Company granted 36,000 DSUs to directors.  As the stock price on the grant date of June 23, 2014 was $5.84, total compensation cost to be recognized is $0.2 million. This cost will be recognized over the requisite service period of one year from the date of grant or the next annual shareholders’ meeting; whichever is earlier. The Company also granted 13,699 DSUs to the Chairman of the Board.  As the stock price on the grant date of June 23, 2014 was $5.84, total compensation cost to be recognized is $0.1 million. This cost will be recognized over a period of five years.  Subsequent to the requisite service period, the awards will vest 100%. These DSUs generally are subject to the same terms as RSUs under the Company’s 2010 Equity Incentive Plan, except that, following vesting, settlement occurs within 30 days following the earlier of separation from the Board or a change in control of the Company.  Subsequent to vesting and prior to delivery, these units will continue to earn dividend equivalents.
	The Company recognized $0.3 million of compensation expense related to non-vested stock units for the three months ended September 30, 2014 and 2013.  The Company recognized $0.8 million and $0.7 million of compensation expense related to non-vested stock units for the nine months ended September 30, 2014 and 2013, respectively.  As of September 30, 2014, there was $3.9 million of total unrecognized compensation cost related to these non-vested stock units.  This cost is expected to be recognized over a period of 3.7 years.

	Note 9:  Outstanding Commitments and Contingent Liabilities
	Legal Matters
	The Company is a party to legal actions which arise in the normal course of its business activities.  In the opinion of management, the ultimate resolution of these matters is not expected to have a material effect on the financial position or the results of operations of the Company.
	Credit Commitments and Contingencies
	The Company is a party to credit-related financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers.  These financial instruments include commitments to extend credit and standby letters of credit.  Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Balance Sheets.
	The Company’s exposure to credit loss is represented by the contractual amount of those commitments.  The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments.  A summary of the contractual amount of the Company’s exposure to off-balance-sheet risk relating to the Company’s commitments to extend credit and standby letters of credit follows:
		September 30, 2014		December 31, 2013
		(dollars in thousands)
	Financial instruments whose contract amounts represent credit risk:
	Commitments to extend credit	$	575,586	$	527,614
	Standby letters of credit	13,601		10,155
	Commitments to extend credit are agreements to lend to a customer as long as no condition established in the contract has been violated.  These commitments are generally at variable interest rates and generally have fixed expiration dates or other termination clauses and may require payment of a fee.  The commitments for equity lines of credit may expire without being drawn upon.  Therefore, the total commitment amounts do not necessarily represent future cash requirements.  The amount of collateral obtained, if it is deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the customer.
	Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer’s obligation to a third party.  Those guarantees are primarily issued to support public and private borrowing arrangements, including bond financing and similar transactions and primarily have terms of one year or less.  The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.  The Company holds collateral, which may include accounts receivable, inventory, property and equipment, and income producing properties, supporting those commitments if deemed necessary.  In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment.  The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount shown in the summary above.  If the commitment is funded, the Company would be entitled to seek recovery from the customer.  As of September 30, 2014 and December 31, 2013, no amounts were recorded as liabilities for the Company’s potential obligations under these guarantees.

	Note 11: Derivative Financial Instruments
	Starting in the first quarter of 2014, the Company began entering into loan agreements that settled in non-U.S. dollar denominations.  The foreign loan balance, gross, translated into U.S. dollars as of September 30, 2014 was $1.4 million.
	Foreign Currency Derivatives. The Company enters into foreign currency forward contracts that are not designated as hedging instruments to mitigate the economic effect of fluctuations in foreign currency exchange rates on certain non-U.S. dollar denominated loans.  Due to the foreign loan activity beginning in 2014, the Company implemented a new accounting policy based on existing accounting standards. Because the foreign currency forward contracts do not meet hedge accounting requirements, gains and losses due to changes in their fair values are recognized in other income.
	The notional amount and fair values of open foreign currency forward contracts were as follows:
		September 30, 2014		December 31, 2013
		(dollars in thousands)
	Forward contracts – foreign exchange:

	Other liabilities – estimated fair value	—		—
	The amount of gains and losses relating to foreign currency forward contracts included in other income for the three and nine months ended September 30, 2014 was insignificant.
	Foreign currency forward contracts involve the risk of dealing with counterparties and their ability to meet contractual terms.  We believe the risk of incurring losses due to nonperformance by our counterparties is manageable.
	As of September 30, 2014, the Company had no other interest rate futures, forwards, swaps or option contracts, or other financial instruments with similar characteristics with the exception of rate lock commitments on mortgage loans to be held for sale, which netted to an insignificant amount.

Fair Value Measurements	'
Fair Value Measurements	'
	Note 12: Fair Value Measurements
	The fair value of an asset or liability is the price that would be received by selling that asset or paid in transferring that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. 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 - Unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
	Level 2 Inputs - Inputs other than quoted prices included in level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.
	Level 3 Inputs - Unobservable inputs for determining the fair values of assets or liabilities that reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.
	A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to those Company assets and liabilities that are carried at fair value.
	There were no transfers between levels during the quarter ended September 30, 2014.
	In general, fair value is based upon quoted market prices, when available. If such quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable data. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect, among other things, counterparty credit quality and the company’s creditworthiness as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.  Furthermore, the reported fair value amounts have not been comprehensively revalued since the presentation dates and, therefore, estimates of fair value after the balance sheet date may differ significantly from the amounts presented herein.
	Securities Available for Sale. Securities classified as available for sale are reported at fair value utilizing level 1 and level 2 measurements. For mutual funds and other equity securities, unadjusted quoted prices in active markets for identical assets are utilized to determine fair value at the measurement date and have been classified as level 1 in the ASC 820 fair value hierarchy.  For all other securities, the Company obtains fair value measurements from an independent pricing service. The independent pricing service evaluations are based on market data.  The independent pricing service utilizes evaluated pricing models that vary by asset class and incorporate available trade, bid and other market information.  Because many fixed income securities do not trade on a daily basis, the independent pricing service evaluated pricing applications apply available information as applicable through processes such as benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing, to prepare evaluations.  In addition, the independent pricing service uses model processes, such as the Option Adjusted Spread model, to assess interest rate impact and develop prepayment scenarios.  The models and processes take into account market convention.  For each asset class, a team of evaluators gathers information from market sources and integrates relevant credit information, perceived market movements and sector news into the evaluated pricing applications and models.
	The market inputs that the independent pricing service normally seeks for evaluations of securities, listed in approximate order of priority, include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data including market research publications.  The independent pricing service also monitors market indicators, industry and economic events.  Information of this nature is a trigger to acquire further market data.  For certain security types, additional inputs may be used or some of the market inputs may not be applicable.  Evaluators may prioritize inputs differently on any given day for any security based on market conditions, and not all inputs listed are available for use in the evaluation process for each security evaluation on a given day.  Because the data utilized was observable, the securities have been classified as level 2 in the ASC 820 fair value hierarchy.
	Derivative Assets and Derivative Liabilities. Derivative assets and derivative liabilities are reported at fair value utilizing level 2 measurements.  Derivative instruments with positive fair values are reported as an asset and derivative instruments with negative fair value are reported as liabilities.  The fair value of derivative assets and liabilities is determined based on prices obtained from a third party.  Values of derivative assets and liabilities are primarily based on observable inputs and are classified as level 2 in the ASC 820 fair value hierarchy.
	The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of September 30, 2014 and December 31, 2013, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value:

	Certain financial assets and financial liabilities are measured at fair value on a non-recurring 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).
	Impaired Loans. The Company does not record loans at fair value on a recurring basis. However, periodically, a loan is considered impaired and is reported at the fair value of the underlying collateral, less estimated costs to sell, if repayment is expected solely from the collateral.  Impaired loans measured at fair value typically consist of loans on non-accrual status and restructured loans in compliance with modified terms.  Collateral values are estimated using a combination of observable inputs, including recent appraisals, and unobservable inputs based on customized discounting criteria. Due to the significance of the unobservable inputs, all impaired loan fair values have been classified as level 3 in the ASC 820 fair value hierarchy.
	OREO.  Non-financial assets and non-financial liabilities measured at fair value include OREO (upon initial recognition or subsequent impairment). OREO properties are measured using a combination of observable inputs, including recent appraisals, and unobservable inputs based on customized discounting criteria. Due to the significance of the unobservable inputs, all OREO fair values have been classified as level 3 in the ASC 820 fair value hierarchy.

FASB ASC Topic 825 requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis. A detailed description of the valuation methodologies used in estimating the fair value of financial instruments is set forth in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
During the third quarter of 2014, the Company executed $30.0 million in Federal Home Loan Bank (“FHLB”) overnight discount note indexed advances.  The variable rate notes range in maturity from seven to ten years with options to prepay at par prior to maturity.
