Basis of Presentation
Basis of Presentation	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, 2014. The accompanying Consolidated Balance Sheet as of December 31, 2014, which has 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 six months ended June 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. 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. There were no significant subsequent events for the quarter ended June 30, 2015 through the issuance date of these consolidated financial statements that warranted adjustment to or disclosure in the consolidated financial statements.

Acquisitions	Note 2: Acquisitions On January 8, 2015, First Busey acquired Herget Financial Corp. (“Herget Financial”), headquartered in Pekin, Illinois and its wholly-owned bank subsidiary, Herget Bank, National Association (“Herget Bank”). First Busey operated Herget Bank as a separate banking subsidiary from January 9, 2015 until March 13, 2015, when it was merged with Busey Bank. At that time, Herget Bank’s three branches in Pekin, Illinois became branches of Busey Bank. The operating results of Herget Financial are included with the Company’s results of operations since the date of acquisition. The acquisition of Herget Financial allowed First Busey to further increase its presence in the Pekin and greater Peoria market. Additionally, Herget Financial held a dominant deposit market position in its community and offered trust, estate and asset management services, as well as competitive commercial loan and mortgage offerings, all of which complement First Busey’s offerings. First Busey acquired 100% of Herget Financial’s outstanding common stock for aggregate cash consideration of $34.1 million which was funded through internal sources. Each shareholder of Herget Financial common stock received $588.00 per share in cash. During the three and six months ended June 30, 2015, expenses related to the acquisition of Herget Financial totaled $0.1 million and $1.0 million, respectively. Additionally, during 2014, First Busey incurred $0.4 million of acquisition expenses related to this transaction. The expenses were comprised primarily of system conversion, restructuring, legal, consulting, regulatory and marketing costs, all of which are reported as a component of other expense in the accompanying unaudited consolidated interim financial statements. This transaction was accounted for using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed, and consideration exchanged were recorded at estimated fair values on the date of acquisition. Fair values are subject to refinement for up to one year after the closing date of January 8, 2015 as additional information regarding the closing date fair values becomes available; however, the Company does not expect any adjustments will be necessary. The following table provides an assessment of the assets purchased and liabilities assumed (dollars in thousands) : Cash and due from banks $ Securities Loans held for sale Loans Premises and equipment Goodwill Other intangible assets Other assets Deposits Other liabilities The loans acquired in this transaction were recorded at fair value with no carryover of any existing allowance for loan losses. Loans that were not deemed to be credit impaired at acquisition were accounted for under Financial Accounting Standards Board (“FASB”) ASC 310-20, Receivables-Nonrefundable Fees and Other Costs and were subsequently considered as part of the Company’s determination for the adequacy of the allowance for loan losses. Purchased credit-impaired (“PCI”) loans, loans with evidence of credit quality deterioration, were accounted for under FASB ASC 310-30, Receivables — Loans and Debt Securities Acquired with Deteriorated Credit Quality . The fair value of the acquired performing loans totaled $103.7 million and the fair value of the PCI loans totaled $1.5 million. The other intangible assets acquired in this transaction will be amortized using an accelerated method over 10 years.

Recent Accounting Pronouncements	Note 3: Recent Accounting Pronouncements Accounting Standards Update (“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 was originally effective for reporting periods after December 15, 2016. In July 2015, the FASB voted to delay the effective date of the ASU by one year. The Company is evaluating the impact this guidance will have on its consolidated financial statements and related disclosures.

Securities	Note 4: 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. The amortized cost, unrealized gains and losses and fair values of securities classified as available for sale and held to maturity are summarized as follows: Gross Gross Amortized Unrealized Unrealized Fair June 30, 2015: Cost Gains Losses Value (dollars in thousands) Available for sale U.S. Treasury securities $ $ $ — $ Obligations of U.S. government corporations and agencies ) Obligations of states and political subdivisions ) Residential mortgage-backed securities ) Corporate debt securities ) Total debt securities ) Mutual funds and other equity securities — Total $ $ $ ) $ Held to maturity Obligations of states and political subdivisions $ $ $ ) $ Commercial mortgage-backed securities — Total $ $ $ ) $ Gross Gross Amortized Unrealized Unrealized Fair December 31, 2014: Cost Gains Losses Value (dollars in thousands) Available for sale U.S. Treasury securities $ $ $ ) $ Obligations of U.S. government corporations and agencies ) Obligations of states and political subdivisions ) Residential mortgage-backed securities ) Corporate debt securities ) Total debt securities ) Mutual funds and other equity securities — Total $ $ $ ) $ Held to maturity Obligations of states and political subdivisions $ $ $ ) $ Commercial mortgage-backed securities — Total $ $ $ ) $ The amortized cost and fair value of debt securities available for sale and held to maturity as of June 30, 2015, by contractual maturity, are shown below. Mutual funds and other equity securities do not have stated maturity dates and therefore are not included in the following maturity summary. Mortgages underlying the residential mortgage-backed securities may be called or prepaid without penalties; therefore, actual maturities could differ from the contractual maturities. All residential mortgage- backed securities were issued by U.S. government agencies and corporations.

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 June 30, 2015 was 188, and represented a loss of 0.6% 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 June 30, 2015. The Company had available for sale obligations of state and political subdivisions with a fair value of $196.0 million and $220.2 million as of June 30, 2015 and December 31, 2014, respectively. In addition, the Company had held to maturity obligations of state and political subdivisions with a fair value of $35.0 million and $1.4 million at June 30, 2015 and December 31, 2014, respectively. As of June 30, 2015, the fair value of the Company’s obligations of state and political subdivisions portfolio was comprised of $194.3 million of general obligation bonds and $36.7 million of revenue bonds issued by 289 issuers, primarily consisting of states, counties, cities, towns, villages and school districts. The Company held investments in general obligation bonds in 30 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, 2014, the Company’s obligations of state and political subdivisions portfolio was comprised of $183.7 million of general obligation bonds and $37.9 million of revenue bonds issued by 220 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 15 states, including two states where the aggregate fair value exceeded $5.0 million. The amortized cost and fair values of the Company’s portfolio of general obligation bonds are summarized in the following tables by the issuers’ state: June 30, 2015: Average Exposure Number of Amortized Fair Per Issuer U.S. State Issuers Cost Value (Fair Value) (dollars in thousands) Illinois $ $ $ Wisconsin Michigan Pennsylvania Ohio Texas Iowa Other Total general obligations bonds $ $ $ December 31, 2014: Average Exposure Number of Amortized Fair Per Issuer U.S. State Issuers Cost Value (Fair Value) (dollars in thousands) Illinois $ $ $ Wisconsin Michigan Pennsylvania Ohio Texas Iowa Other Total general obligations bonds $ $ $ The general obligation bonds are diversified across many issuers, with $3.4 million being the largest exposure to a single issuer at June 30, 2015 and December 31, 2014. Accordingly, as of June 30, 2015 and December 31, 2014, 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, 98.0% had been rated by at least one nationally recognized statistical rating organization and 2.0% were unrated, based on the fair value as of June 30, 2015. Of the general obligation bonds in the Company’s portfolio, 97.1% had been rated by at least one nationally recognized statistical rating organization and 2.9% were unrated, based on the fair value as of December 31, 2014. The amortized cost and fair values of the Company’s portfolio of revenue bonds are summarized in the following tables by the issuers’ state: June 30, 2015: Average Exposure Number of Amortized Fair Per Issuer U.S. State Issuers Cost Value (Fair Value) (dollars in thousands) Illinois $ $ $ Indiana Other Total revenue bonds $ $ $ December 31, 2014: Average Exposure Number of Amortized Fair Per Issuer U.S. State Issuers Cost Value (Fair Value) (dollars in thousands) Illinois $ $ $ Indiana Other Total revenue bonds $ $ $ 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 June 30, 2015 and December 31, 2014. Accordingly, as of June 30, 2015 and December 31, 2014, 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 June 30, 2015 and December 31, 2014. 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 June 30, 2015, 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.

Net deferred loan origination costs included in the tables above were $0.7 million as of June 30, 2015 and $0.6 million as of December 31, 2014. Gross loans increased to $2.51 billion at June 30, 2015 from $2.41 billion at December 31, 2014 as a result of organic growth and the addition of loans obtained as part of the Herget Financial acquisition. The Company believes that making sound loans is 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, 2014. 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. Most commercial lending relationships 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 receive a portfolio review at least annually. 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 $2.32 billion at June 30, 2015 compared to $2.28 billion at December 31, 2014. Loans in the lowest grades, represented by grades 8, 9 and 10, totaled $162.0 million at June 30, 2015, compared to $124.0 million at December 31, 2014. The June 30, 2015 totals reflect the post-combination results of acquiring Herget Financial. The following table presents weighted average risk grades segregated by category of loans (excluding held for sale, loan accretion, non-posted and clearings) and geography: June 30, 2015 Weighted Avg.

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: June 30, 2015 Loans past due, still accruing Non- 30-59 Days 60-89 Days 90+Days accrual Loans (dollars in thousands) Illinois/Indiana Commercial $ $ $ — $ Commercial real estate — — Real estate construction — — Retail real estate — Retail other — — Total Illinois/Indiana $ $ $ — $ Florida Commercial $ — $ — $ — $ Commercial real estate — — — Real estate construction — — — Retail real estate — Retail other — — — — Total Florida $ $ — $ $ Total $ $ $ $ December 31, 2014 Loans past due, still accruing Non- 30-59 Days 60-89 Days 90+Days accrual Loans (dollars in thousands) Illinois/Indiana Commercial $ $ $ — $ Commercial real estate — Real estate construction — — — Retail real estate — Retail other — — Total Illinois/Indiana $ $ $ $ Florida Commercial $ — $ — $ — $ Commercial real estate — — — Real estate construction — — — Retail real estate — — — Retail other — — — — Total Florida $ — $ — $ — $ Total $ $ $ $ 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 $0.35 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. PCI loans are considered impaired. 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 six months ended June 30, 2015 if impaired loans had been current in accordance with their original terms was $0.1 million and $0.2 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 six months ended June 30, 2015. 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 June 30, 2015 and December 31, 2014 is as follows: June 30, 2015 December 31, 2014 (dollars in thousands) Restructured loans: In compliance with modified terms $ $ 30 — 89 days past due — Included in non-performing loans Total $ $ 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. Performing loans classified as TDRs during the three months ended June 30, 2015 included one retail real estate modification in Illinois/Indiana for short-term interest rate relief, with a recorded investment of $0.1 million. Performing loans classified as TDRs during the six months ended June 30, 2015 included one retail real estate modification in Illinois/Indiana for short-term interest rate relief, with a recorded investment of $0.1 million, two retail real estate modifications in Illinois/Indiana for short-term principal payment relief, with a recorded investment of $0.1 million and two retail real estate modifications in Florida for short-term principal payment relief, with a recorded investment of $0.3 million. Performing loans classified as TDRs during the three and six months ended June 30, 2014 were insignificant. The gross interest income that would have been recorded in the three and six months ended June 30, 2015 and 2014 if performing TDRs had been in accordance with their original terms instead of modified terms was insignificant. TDRs that were entered into during the last twelve months that subsequently 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 months ended June 30, 2015 consisted of one Illinois/Indiana commercial real estate modification totaling $1.0 million. TDRs that were entered into during the last twelve months that subsequently were classified as non-performing and had payment defaults during the six months ended June 30, 2015 consisted of one Illinois/Indiana commercial real estate modification totaling $1.0 million and one Florida commercial modification totaling $1.0 million. There were no TDRs that were entered into during the last twelve months that subsequently were classified as non-performing and had payment defaults during the three and six months ended June 30, 2014. 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.

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 June 30, 2015 and December 31, 2014. 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 June 30, 2015 and December 31, 2014, which is an estimate of the additional loss inherent in these loan grades based upon a review of overall historical charge-offs. As of June 30, 2015, 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 June 30, 2015 and December 31, 2014, based upon a review of the differences between the rolling 12- and 20-quarter historical loss averages by region. As of June 30, 2015, 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 second quarter of 2015, the Company adjusted Illinois/Indiana qualitative factors relating to Macro and Local Economic Factor and Nature and Volume of Loan Portfolio. The adjustment of these factors increased our allowance requirements by $1.8 million at June 30, 2015 compared to the method used for March 31, 2015. Adjustments to increase these qualitative factors were made 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.

OREO
OREO	Note 6: OREO OREO represents properties acquired through foreclosure or other proceedings in settlement of loans. OREO is held for sale and is recorded at the date of foreclosure at the fair value of the properties less estimated costs of disposal, which establishes a new cost basis. Any adjustment to fair value at the time of transfer to OREO is charged to the allowance for loan losses. Property is evaluated regularly to ensure the recorded amount is supported by its current fair value, and valuation allowances to reduce the carrying amount to fair value less estimated costs to dispose are recorded as necessary. Revenue, expense, gains and losses from the operations of foreclosed assets are included in operations. At June 30, 2015, the Company held $0.1 million in commercial OREO, $0.2 million in residential OREO and an insignificant amount of other repossessed assets. At December 31, 2014, the Company held $0.2 million of other repossessed assets. At June 30, 2015 the Company had $1.3 million of residential real estate in the process of foreclosure.

Securities Sold Under Agreements to Repurchase	Note 7: Securities Sold Under Agreements to Repurchase Securities sold under agreements to repurchase, which are classified as secured borrowings, generally mature either daily or within one year from the transaction date. Securities sold under agreements to repurchase are reflected at the amount of cash received in connection with the transaction. The underlying securities are held by the Company’s safekeeping agent. The Company may be required to provide additional collateral based on the fair value of the underlying securities. The following table sets forth the distribution of securities sold under agreements to repurchase and weighted average interest rates: June 30, 2015 December 31, 2014 (dollars in thousands) Balance at end of period $ $ Weighted average interest rate at end of period % % Maximum outstanding at any month end in year-to-date period $ $ Average daily balance for the year-to-date period $ $ Weighted average interest rate during period (1) % % (1)The weighted average interest rate is computed by dividing total annualized interest for the year-to-date period by the average daily balance 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 June 30, 2015, 259,756 outstanding options, 573,833 warrants, and 380,531 restricted stock units were anti-dilutive and excluded from the calculation of common stock equivalents. At June 30, 2014, 476,230 outstanding options, 573,833 warrants, and 353,976 restricted stock units were anti-dilutive and excluded from the calculation of common stock equivalents.

Share-based Compensation.
Share-based Compensation	Note 9: Share-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 grants RSUs to members of management periodically throughout the year. Each RSU is equivalent to one share of the Company’s common stock. These units have a requisite service period ranging from one to five years. The Company annually grants share-based awards in the form of DSUs, which are RSUs with a deferred settlement date, to its board of directors. Each DSU is equivalent to one share of the Company’s common stock. The DSUs vest over a twelve-month period following the grant date or on the date of the next annual shareholder’s meeting, whichever is earlier. These units 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 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 June 30, 2015, the Company held 1,381,951 shares in treasury. On February 3, 2015, First Busey announced that its board of directors approved a repurchase plan under which the Company is authorized to repurchase, from time to time as the Company deems appropriate, up to an aggregate of two million shares of its common stock. The repurchase plan has no expiration date and replaced the prior repurchase plan that was originally approved in 2008. A description of the 2010 Equity Incentive Plan can be found in the Company’s Proxy Statement for the 2015 Annual Meeting of Stockholders. 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 six months ended June 30, 2015 follows: Weighted- Weighted- Average Average Exercise Remaining Contractual Shares Price Term Outstanding at beginning of year $ Granted — — Exercised — — Forfeited Expired Outstanding at end of period $ Exercisable at end of period $ The Company did not record any stock option compensation expense for the three and six months ended June 30, 2015 or 2014. A summary of the changes in the Company’s stock unit awards for the six months ended June 30, 2015, is as follows: Director Weighted- Restricted Deferred Average Stock Stock Grant Date Units Units Total Fair Value Non-vested at beginning of year $ Granted Dividend Equivalents Earned Vested ) ) ) Forfeited ) — ) Non-vested at end of period $ Outstanding at end of period $ 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 (though not required) to be issued from treasury. On June 25, 2015, under the terms of the 2010 Equity Incentive Plan, the Company granted 326,836 RSUs to members of management. As the stock price on the grant date of June 25, 2015 was $6.69, total compensation cost to be recognized is $2.2 million. This cost will be recognized over a period of five years. Subsequent to the requisite service period, the awards will vest 100%. In addition, on June 25, 2015, under the terms of the 2010 Equity Incentive Plan, the Company granted 38,000 DSUs to directors. As the stock price on the grant date of June 25, 2015 was $6.69, total compensation cost to be recognized is $0.3 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 15,695 DSUs to the Chairman of the board. As the stock price on the grant date of June 25, 2015 was $6.69, 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%. The Company recognized $0.3 million of compensation expense related to non-vested stock units for the three months ended June 30, 2015 and 2014. The Company recognized $0.6 million and $0.5 million of compensation expense related to non-vested stock units for the six months ended June 30, 2015 and 2014, respectively. As of June 30, 2015, there was $5.3 million of total unrecognized compensation cost related to these non-vested stock units. This cost is expected to be recognized over a period of 3.9 years.

Outstanding Commitments and Contingent Liabilities
Outstanding Commitments and Contingent Liabilities	Note 11: 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: June 30, 2015 December 31, 2014 (dollars in thousands) Financial instruments whose contract amounts represent credit risk: Commitments to extend credit $ $ Standby letters of credit 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 June 30, 2015 and December 31, 2014, no amounts were recorded as liabilities for the Company’s potential obligations under these guarantees.

Capital
Capital	Note 12: Capital The ability of the Company to pay cash dividends to its stockholders and to service its debt historically was dependent on the receipt of cash dividends from its subsidiaries. However, Busey Bank sustained significant losses during 2008 and 2009 resulting in pressure on its capital, which was relieved through injections of capital from the Company. State chartered banks have certain statutory and regulatory restrictions on the amount of cash dividends they may pay. Due to the significant losses in the past and the Company’s desire to maintain a strong capital position at Busey Bank, no dividends have been paid from Busey Bank since 2009. Until such time as retained earnings have been restored, Busey Bank will not be permitted to pay dividends, and we will need to request permission from Busey Bank’s primary regulator to distribute any capital out of Busey Bank. On January 22, 2013, with the approval of its primary regulator, Busey Bank transferred $50.0 million to the Company, representing a return of capital and associated surplus as a result of an amendment to Busey Bank’s charter. Further, on October 22, 2014, with the approval of its primary regulator, Busey Bank transferred $60.0 million to the Company, representing a return of capital and associated surplus as a result of a further amendment to Busey Bank’s charter. The Company and Busey Bank are subject to regulatory capital requirements administered by federal and state banking agencies that involve the quantitative measure of their assets, liabilities, and certain off-balance-sheet items, as calculated under regulatory accounting practices. Quantitative measures established by regulations to ensure capital adequacy require the Company and Busey Bank to maintain minimum amounts and ratios (set forth in the table below) of total, Tier 1 capital and Common Equity Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined in the regulations), and, for the Bank, Tier 1 capital (as defined in the regulations) to average assets (as defined in the regulations). Failure to meet minimum capital requirements may cause regulatory bodies to initiate certain discretionary and/or mandatory actions that, if undertaken, may have a direct material effect on our financial statements. The Company, as a financial holding company, is required to be “well capitalized” in the capital categories shown in the table below. As of June 30, 2015, the Company and Busey Bank met all capital adequacy requirements to which they were subject, including the guidelines to be considered “well capitalized.” Minimum Minimum To Be Actual Capital Requirement Well Capitalized Amount Ratio Amount Ratio Amount Ratio (dollars in thousands) As of June 30, 2015: Total Capital (to Risk Weighted Assets) Consolidated $ % $ % $ % Busey Bank $ % $ % $ % Tier 1 Capital (to Risk Weighted Assets) Consolidated $ % $ % $ % Busey Bank $ % $ % $ % Common Equity Tier 1 Capital (to Risk Weighted Assets) Consolidated $ % $ % $ % Busey Bank $ % $ % $ % Tier 1 Capital (to Average Assets) Consolidated $ % $ % N/A N/A Busey Bank $ % $ % $ % On July 21, 2010, President Obama signed the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) into law, which required the Board of Governors of the Federal Reserve System to establish minimum capital levels for bank holding companies on a consolidated basis that are as stringent as those required for insured depository institutions. The components of Tier 1 capital were restricted to capital instruments that at the time of signing were considered to be Tier 1 capital for insured depository institutions. As a result, the proceeds of trust preferred securities are excluded from Tier 1 capital unless such securities were issued prior to May 19, 2010 by bank holding companies with less than $15.0 billion of assets. As the Company has assets of less than $15.0 billion, it is able to maintain its trust preferred proceeds as Tier 1 capital but it will have to comply with new capital mandates in other respects, and it will not be able to raise Tier 1 capital through the issuance of trust preferred securities in the future. In July 2013, the U.S. federal banking authorities approved the implementation of the Basel III regulatory capital reforms and issued rules effecting certain changes required by the Dodd-Frank Act (the “Basel III Rules”). The Basel III Rules are applicable to all U.S. banks that are subject to minimum capital requirements, as well as to bank and savings and loan holding companies other than “small bank holding companies” (generally non-public bank holding companies with consolidated assets of less than $1 billion). The Basel III Rules not only increased most of the required minimum regulatory capital ratios, but they also introduced a new Common Equity Tier 1 Capital ratio and the concept of a capital conservation buffer. The Basel III Rules also expanded the definition of capital as in effect currently by establishing criteria that instruments must meet to be considered Additional Tier 1 Capital (Tier 1 Capital in addition to Common Equity) and Tier 2 Capital. A number of instruments that generally qualified as Tier 1 Capital no longer qualify, or their qualifications changed, as the Basel III Rules are fully implemented. The Basel III Rules also permitted banking organizations with less than $15.0 billion in assets to retain, through a one-time election, the past treatment for accumulated other comprehensive income, which did not affect regulatory capital. First Busey and the Bank made this election in the first quarter of 2015 to avoid variations in the level of their capital depending on fluctuations in the fair value of their securities portfolio. The Basel III Rules maintained the general structure of the prompt corrective action framework, while incorporating increased requirements. The prompt corrective action guidelines were also revised to add the Common Equity Tier 1 Capital ratio. In order to be a “well-capitalized” depository institution under the new Basel III Rules, a bank and holding company must maintain a Common Equity Tier 1 Capital ratio of 6.5% or more; a Tier 1 Capital ratio of 8% or more; a Total Capital ratio of 10% or more; and a leverage ratio of 5% or more. Financial institutions became subject to the new Basel III Rules on January 1, 2015, with phase-in periods for many of the changes. As of June 30, 2015, the Company and the Bank were in compliance with the current phase Basel III Rules and management believes that the Company and the Bank would meet all capital adequacy requirements under the Basel III Rules on a fully phased-in basis as if such requirements had been in effect.

Fair Value Measurements

Fair Value Measurements
Fair Value Measurements	Note 14: 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. Cash and due from banks were transferred to level 1 as of June 30, 2015 as carrying amount approximates fair value. There were no additional transfers between levels during the quarter ended June 30, 2015. 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 June 30, 2015 and December 31, 2014, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value: Level 1 Level 2 Level 3 Total Inputs Inputs Inputs Fair Value (dollars in thousands) June 30, 2015 Securities available for sale U.S. Treasury securities $ — $ $ — $ Obligations of U.S. government corporations and agencies — — Obligations of states and political subdivisions — — Residential mortgage-backed securities — — Corporate debt securities — — Mutual funds and other equity securities — — Derivative assets Foreign currency forward contracts — — Level 1 Level 2 Level 3 Total Inputs Inputs Inputs Fair Value (dollars in thousands) December 31, 2014 Securities available for sale U.S. Treasury securities $ — $ $ — $ Obligations of U.S. government corporations and agencies — — Obligations of states and political subdivisions — — Residential mortgage-backed securities — — Corporate debt securities — — Mutual funds and other equity securities — — Derivative assets Foreign currency forward contracts — — 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. The following table summarizes assets and liabilities measured at fair value on a non-recurring basis as of June 30, 2015 and December 31, 2014, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value: Level 1 Level 2 Level 3 Total Inputs Inputs Inputs Fair Value (dollars in thousands) June 30, 2015 Impaired loans $ — $ — $ $ OREO — — December 31, 2014 Impaired loans $ — $ — $ $ The following table presents additional quantitative information about assets measured at fair value on a non-recurring basis for which the Company has utilized level 3 inputs to determine fair value: Quantitative Information about Level 3 Fair Value Measurements Fair Value Valuation Unobservable Range Estimate Techniques Input (Weighted Average) (dollars in thousands) June 30, 2015 Impaired loans $ Appraisal of collateral Appraisal adjustments -6.0% to -100.0% (-51.6)% OREO Appraisal of collateral Appraisal adjustments -52.9% to -100.0% (-90.9)% December 31, 2014 Impaired loans $ Appraisal of collateral Appraisal adjustments -7.7% to -100.0% (-54.3)% The estimated fair values of financial instruments that are reported at amortized cost in the Company’s Consolidated Balance Sheets, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value, were as follows: June 30, 2015 December 31, 2014 Carrying Fair Carrying Fair Amount Value Amount Value (dollars in thousands) Financial assets: Level 1 inputs: Cash and due from banks $ $ $ — $ — Level 2 inputs: Cash and due from banks — — Securities held to maturity Loans held for sale Accrued interest receivable Level 3 inputs: Loans, net Financial liabilities: Level 2 inputs: Deposits $ $ $ $ Securities sold under agreements to repurchase Long-term debt Junior subordinated debt owed to unconsolidated trusts Accrued interest payable The fair value of loans, net reflects general changes in the interest rate curve used to calculate fair values based on cash flows.
