Significant Accounting Policies | Note 1. Significant Accounting Policies Description of business First Busey Corporation is a Nevada corporation and a financial holding company. The Company’s subsidiaries provide retail and commercial banking services, remittance processing, and offer a full range of financial products and services, including depository, lending, security brokerage services, investment management and fiduciary services, to individual, corporate, institutional and governmental customers through its locations in Illinois, Missouri, southwest Florida and Indianapolis, Indiana. The Company and its subsidiaries are subject to competition from other financial institutions and non-financial institutions providing financial products and services. The Company and its subsidiaries are also subject to the regulations of certain regulatory agencies and undergo periodic examinations by those regulatory agencies. All share and per share information has been restated for all prior periods presented in this Annual Report on Form 10-K to give retroactive effect to the Reverse Stock Split. The significant accounting and reporting policies for the Company and its subsidiaries follow: Basis of consolidation The Consolidated Financial Statements include the accounts of the Company and its subsidiaries: Busey Bank and its wholly-owned subsidiaries FirsTech, Inc. and Pulaski Service Corporation; and Busey Wealth Management, Inc. and its wholly-owned subsidiaries Busey Trust Company and Busey Capital Management, Inc. The Company and its subsidiaries maintain various LLCs that hold specific assets for risk mitigation purposes and are consolidated into these financial statements. All significant intercompany balances and transactions have been eliminated in consolidation. The Consolidated Financial Statements also exclude the following wholly-owned variable interest entities: First Busey Statutory Trust II, First Busey Statutory Trust III, First Busey Statutory Trust IV, Pulaski Financial Statutory Trust I and Pulaski Financial Statutory Trust II because the Company is not the primary beneficiary. The Consolidated Financial Statements of the Company have been prepared in conformity with GAAP and conform to predominant practice within the banking industry. Use of estimates In preparing the accompanying Consolidated Financial Statements in conformity with GAAP, 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, fair value of assets acquired and liabilities assumed in business combinations and the determination of the allowance for loan losses. Comprehensive income Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities, are reported as a separate component of the equity section of the balance sheet, such items, along with net income, are components of comprehensive income. Trust assets Assets held for customers in a fiduciary or agency capacity, other than trust cash on deposit at the Company’s bank subsidiary, are not assets of the Company and, accordingly, are not included in the accompanying Consolidated Financial Statements. Busey Trust Company had assets under care of $5.4 billion and $5.1 billion at December 31, 2016 and 2015, respectively. Cash flows For purposes of the Consolidated Statement of Cash Flows, cash and cash equivalents includes cash on hand, amounts due from banks and federal funds sold. Cash flows from federal funds purchased and sold, short-term borrowings, and securities sold under agreements to repurchase are reported net, since their original maturities are less than three months. Cash flows from loans and deposits are also reported net. Securities Securities classified as held to maturity are those debt securities that the Company intends to hold to maturity. Securities held to maturity are carried at cost, adjusted for amortization of premiums and accretion of discounts. Securities classified as available for sale are those debt securities that the Company intends to hold for an indefinite period of time, but not necessarily to maturity, and marketable equity securities. Any decision to sell a security classified as available for sale would be based on various factors, including significant movements in interest rates, changes in the maturity mix of the Company’s assets and liabilities, liquidity needs, regulatory capital considerations and other similar factors. Securities available for sale are carried at fair value, with temporary unrealized gains and losses excluded from earnings and reported in other comprehensive income. Declines in the fair value of debt securities below their amortized cost are evaluated to determine whether they are temporary or OTTI. If the Company (a) has the intent to sell a debt security or (b) more likely than not will be required to sell the debt security before its anticipated recovery, then the Company recognizes the entire unrealized loss in earnings as an OTTI loss. If neither of these conditions are met, the Company evaluates whether a credit loss exists. The impairment is separated into (x) the amount of the total impairment related to the credit loss and (y) the amount of total impairment related to all other factors. The amount of the total OTTI related to the credit loss is recognized in earnings and the amount related to all other factors is recognized in other comprehensive income. The Company also evaluates whether the decline in fair value of an equity security is temporary or OTTI. In determining whether an unrealized loss on an equity security is temporary or OTTI, management considers various factors, including the magnitude and duration of the impairment, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to hold the equity security to forecasted recovery. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. Loans held for sale Loans held for sale consist of loans that management does not intend to hold until maturity. These loans consist of mortgage loans conforming to established guidelines and held for sale to investors and the secondary mortgage market. Loans held for sale are reflected at their fair values, as the Company has elected to apply the fair value method of accounting, with changes in fair value recognized in earnings, consistent with the provisions in ASC Topic 820, Fair Value Measurement . The Company accounted for loans held for sale that were originated prior to January 1, 2016 under the lower of cost or fair value option, with any corresponding adjustments recorded as a valuation adjustment, if necessary. Fair value adjustments are recorded as an adjustment to mortgage revenues. The fair value of the loans held for sale are measured using observable quoted market or contract prices or market price equivalents, which are consistent with those used by other market participants. Consistent with the fair value principles of ASC Topic 820, any direct loan origination fees and costs related to loans accounted for at fair value are recognized when the loans are sold. Loan servicing Servicing assets are recognized as separate assets when rights are acquired or retained through the sale of mortgage loans. Mortgage servicing rights are initially recorded at fair value. Fair value is based on a valuation model that calculates the present value of estimated future net servicing income. Capitalized servicing rights are reported in other assets and are amortized into other income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Mortgage servicing rights are periodically evaluated for impairment based on the fair value of those rights as compared to book value. Fair values are estimated using discounted cash flows based on current expected future prepayment rates. For purposes of measuring impairment, the rights must be stratified by one or more predominant risk characteristics of the underlying loans. The Company stratifies its capitalized mortgage servicing rights based on the type of the underlying loans. The amount of impairment recognized is the amount, if any, by which the amortized cost of the rights for each stratum exceeds its fair value. If the Company later determines that all or a portion of the impairment no longer exists for a particular group of loans, a reduction of the allowance may be recorded as an increase to income. The Company had no impairment recorded at December 31, 2016 and 2015. Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal and are recorded as income when earned. The amortization of mortgage servicing rights is included in mortgage revenue. Portfolio loans Loan receivables that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported at the principal balance outstanding, net of purchase premiums and discounts, charge-offs, the allowance for loan losses, and any deferred origination fees or costs on loans. Retail loan origination fees, net of certain direct loan origination costs, are deferred and the net amount is amortized as an adjustment of the related loan’s yield. The Company is generally amortizing these amounts over the contractual life. However, for long-term, fixed-rate residential mortgages, the Company has anticipated prepayments and assumes an estimated economic life of five years or less. Material commercial loan origination fees are amortized over the life of the loan which is usually a term of three years or less. Commitment fees and costs are generally based upon a percentage of a customer’s maximum line of credit or fees related to standby letters of credit and are recognized as collected. Interest income is accrued daily on the outstanding balances. 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. Past due status is based on the contractual terms of the loan. Interest accrued in the current year but not collected for loans that are placed on non-accrual status or charged-off is reversed against interest income. Interest accrued during the prior year but not collected for loans that are placed on non-accrual status or charged-off is charged against the allowance for loan losses. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Purchased credit-impaired loans In conjunction with business combinations, the Company purchases loans, some of which have shown evidence of credit deterioration since origination. These purchased credit-impaired (“PCI”) loans are recorded at fair value at acquisition date, factoring in credit losses expected to be incurred over the life of the loan. Accordingly, the seller’s allowance for loan losses is not carried over or recorded as of the acquisition date. PCI loans are reviewed individually or aggregated into pools of loans based on common risk characteristics. The Company estimates the amount and timing of expected cash flows and the excess of the cash flows expected to be collected over the recorded investment, if material, is considered to be the accretable yield and is recognized as interest income over the life. The excess of the contractual cash flows over the cash flows expected to be collected is considered to be the nonaccretable difference. Over the life, expected cash flows continue to be estimated and any increases in expected cash flows over those expected at purchase date in excess of fair value that are significant and probable are adjusted through the accretable yield on a prospective basis. Any subsequent decreases in expected cash flows over those expected at purchase date that are probable are recognized by recording an allowance for loan losses. Allowance for loan losses The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. 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. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectibility of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. In addition, regulatory agencies, as an integral part of their examination process, periodically review the allowance for loan losses, and may require the Company to make additions to the allowance based on their judgment about information available to them at the time of their examinations. The allowance consists of specific and general components. The specific component considers loans that are classified as impaired. For such loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying amount of that loan. The general component covers non-classified loans and classified loans not considered impaired, and is based on historical loss experience adjusted for qualitative factors. Other adjustments may be made to the allowance for pools of loans after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss experience. Premises and equipment, net Land is stated at cost less accumulated depreciation of depreciable land improvements. Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed principally by the straight-line method over the estimated useful lives of the assets. The estimated useful lives for premises and equipment are: Asset Description Estimated Useful Life Buildings and improvements 3 – 40 years Furniture and equipment 3 – 10 years Long-lived assets Long-lived assets, including premises and equipment and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. An impairment loss would be recognized when estimated undiscounted future cash flows from operations of the asset are less than the carrying value of the asset. The cash flows used for this analysis are those directly associated with and that are expected to arise as a direct result of the use and eventual disposition of the asset. An impairment loss would be measured by the amount by which the carrying value of the asset exceeds its fair value. Other real estate owned 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. Goodwill Goodwill represents the excess of the cost of a business acquired over the fair value of the new assets acquired. Goodwill is not amortized, but is subject to at least annual impairment assessments. The Company has established December 31 as the annual impairment assessment date. Accounting standards allow for goodwill to be tested for impairment by first performing a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying value. As part of this analysis, the reporting unit’s carrying value is compared to its fair value. The Company estimates the fair value of its reporting units as of the measurement date utilizing valuation methodologies including the comparable transactions approach and the control premium approach. Goodwill is considered impaired if the carrying value of the reporting unit exceeds its fair value. There was no impairment determined at December 31, 2016 and 2015. It is possible the Company will evaluate its goodwill for impairment on a more frequent basis than annually. Future evaluations may result in impairment. See “ Note 10. Goodwill and Other Intangible Assets” for further discussion. Cash surrender value of bank-owned life insurance The Company has purchased life insurance policies on certain executives and senior officers. Life insurance is recorded at its cash surrender value. ASC Topic 715, “Compensation—Retirement Benefits” requires an employer to recognize a liability for post-employment benefits promised to an employee based on an arrangement between an employer and an employee. In an endorsement split-dollar arrangement, the employer owns and controls the policy, and the employer and employee split the life insurance policy’s cash surrender value and/or death benefits. If the employer agrees to maintain a life insurance policy during the employee’s retirement, the present value of the cost of maintaining the insurance policy would be accrued over the employee’s active service period. Similarly, if the employer agrees to provide the employee with a death benefit, the present value of the death benefit would be accrued over the employee’s active service period. The Company has an accrued liability, included in other liabilities, for this arrangement. Transfers of financial assets Transfers of financial assets are accounted for as sales only when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when: (1) the assets have been isolated from the Company, (2) the transferee obtains the right to pledge or exchange the assets it received, and no condition both constrains the transferee from taking advantage of its right to pledge or exchange and provides more than a modest benefit to the transferor, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets. Income taxes The Company is subject to income taxes in the U.S. federal and various state jurisdictions. The Company and its subsidiaries file consolidated federal and state income tax returns with each subsidiary computing its taxes on a separate entity basis. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. With few exceptions, the Company is no longer subject to U.S. federal, state or local tax examinations by tax authorities for the years before 2012. The provision for income taxes is based on income as reported in the Consolidated Financial Statements. The Company has maintained significant net deferred tax assets for deductible temporary differences, the largest of which relates to the allowance for loan losses. For income tax return purposes, only actual charge-offs are deductible, not the provision for loan losses. Under GAAP, a valuation allowance is required to be recognized if it is more likely than not that the deferred tax assets will not be realized. The determination of the recoverability of the deferred tax assets is highly subjective and dependent upon judgment concerning management’s evaluation of both positive and negative evidence, the forecasts of future income, applicable tax planning strategies, and assessments of the current and future economic and business conditions. The Company evaluated the recoverability of its net deferred tax assets and established a valuation allowance for certain state net operating loss carryforwards and capital loss carryforwards that are not expected to be fully realized. Management believes that it is more likely than not that the deferred tax assets included in the accompanying Consolidated Financial Statements will be fully realized. The Company determined that no valuation allowance was required for any other deferred tax assets as of December 31, 2016, although there is no guarantee that those assets will be recognizable in future periods. Positions taken in tax returns may be subject to challenge upon examination by the taxing authorities. Uncertain tax positions are initially recognized in the Financial Statements when it is more likely than not the position will be sustained upon examination by the tax authorities. Such tax positions are both initially and subsequently measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon settlement with the tax authority, assuming full knowledge of the position and all relevant facts. When applicable, the Company recognizes interest accrued related to unrecognized tax benefits and penalties in operating expenses. The Company had no accruals for payments of interest and penalties at December 31, 2016 and 2015. At December 31, 2016, the Company was not under examination by any tax authority. Treasury Stock Treasury stock acquired is recorded at cost. Treasury stock issued is valued based on the “first-in, first-out” method. Gains and losses on issuance are recorded as increases or decreases to surplus. Stock-based employee compensation During the first quarter of 2010, the Company adopted the First Busey Corporation 2010 Equity Incentive Plan (“2010 Equity Plan”), which was approved at the annual stockholders meeting on May 19, 2010. During the second quarter of 2015, the Company adopted an amendment to revise some technical terms to the 2010 Equity Plan, which was approved at the annual stockholders meeting on May 20, 2015, and can be found as Appendix C of the Company’s Proxy Statement for the 2015 Annual Meeting of Stockholders. The Company will make all future grants under this plan. The Company’s equity incentive plans are designed to encourage ownership of its common stock by its employees and directors, to provide additional incentive for them to promote the success of the Company’s 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 plans. See “ Note 17. Share-based Compensation” for further discussion. The Company calculates the compensation cost of its non-vested stock awards (restricted stock units) based on the Company’s stock price on the grant date multiplied by the number of units granted. This cost is recorded over a specified requisite service period (i.e. vesting period) ranging from one to five years. As the units cliff vest and are subject only to a service condition, the cost is recorded using straight-line amortization. No compensation cost is recognized for unvested awards that are forfeited. Segment disclosure Operating segments are components of a business that (i) engage in business activities from which it may earn revenues and incur expenses; (ii) have operating results that are reviewed regularly by the entity’s chief operating decision maker to make decisions about resources to be allocated to the segments and assess their performance; and (iii) for which discrete financial information is available. The Company’s operations are managed along three operating segments consisting of Banking, Remittance Processing and Wealth Management. Business Combinations Business combinations are accounted for under ASC 805, Business Combinations , using the acquisition method of accounting. The acquisition method of accounting requires an acquirer to recognize the assets acquired and the liabilities assumed at the acquisition date measured at their fair values as of that date. To determine the fair values, the Company may rely on third-party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques. Under the acquisition method of accounting, the Company will identify the acquirer and the closing date and apply applicable recognition principles. On April 30, 2016, First Busey completed its acquisition of Pulaski, a Missouri corporation. On January 8, 2015, First Busey completed its acquisition of Herget Financial, headquartered in Pekin, Illinois. The operating results of both are included with the Company’s results of operations since each date of acquisition. See “ Note 2. Acquisitions ” in the Notes to the Consolidated Financial Statements for further information relating to these acquisitions. Acquisition related costs are costs the Company incurs to effect a business combination. Those costs may include legal, accounting, valuation, other professional or consulting fees, system conversions and marketing costs. The Company will account for acquisition related costs as expenses in the periods in which the costs are incurred and the services are received. Costs that the Company expects, but is not obligated to incur in the future, to effect its plan to exit an activity of an acquiree or to terminate the employment of an acquiree’s employees are not liabilities at the acquisition date. Instead, the Company will recognize these costs in its post-combination financial statements in accordance with other applicable accounting guidance. Derivative Financial Instruments The Company enters into derivative financial instruments, including interest rate lock commitments issued to residential loan customers for loans that will be held for sale, forward sales commitments to sell residential mortgage loans to loan investors and foreign currency forward contracts. These instruments have certain interest rate risk characteristics that change in value based upon changes in the capital markets. Interest Rate Lock Commitments. Commitments to originate loans held for sale (interest rate lock commitments), which primarily consist of commitments to originate fixed-rate residential mortgage loans, are recorded at their fair value in other assets or other liabilities in the Consolidated Financial Statements, with changes in the fair value of the corresponding derivative financial assets or liabilities recorded as either a charge or credit to mortgage revenues during the period in which the changes occurred. Such derivative financial instruments are recorded as an adjustment to the carrying value of the resulting loan once funded. Forward Sales Commitments. As a general rule, the Company economically hedges loans held for sale and interest rate lock commitments issued to its residential loan customers related to loans that will be held for sale by obtaining corresponding best-efforts forward sales commitments with an investor to sell the loans at an agreed-upon price at the time the interest rate locks are issued to the customers. Forward sales commitments that meet the definition of derivative financial instruments under ASC Topic 815, Derivatives and Hedging, are carried at their fair value in other assets or other liabilities in the Consolidated Financial Statements. The Company does not designate these forward sales commitments for hedge accounting treatment, and accordingly, changes in fair value of the corresponding derivative financial asset or liability are recorded as either a charge or credit to mortgage revenue during the period in which the changes occur. Foreign Currency Derivatives. The Company enters into derivative financial instruments as part of its foreign currency risk management strategies. These derivative financial instruments consist of foreign currency forward contracts to accommodate the business needs of its customers. They are carried at their fair value in other assets or other liabilities in the Consolidated Financial Statements. The Company does not designate these foreign currency forward contracts for hedge accounting treatment, and accordingly, changes in fair value of the corresponding derivative financial asset or liability are recorded in non-interest income and expense. Earnings per share 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, which include deferred stock units that are vested but not delivered. 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 December 31, 2016, 28,350 outstanding options, 191,278 warrants and 132,017 restricted stock units were anti-dilutive and excluded from the calculation of common stock equivalents. At December 31, 2015, 61,568 outstanding options and 191,278 warrants were anti-dilutive and excluded from the calculation of common stock equivalents. Earnings per common share, adjusted to reflect the Reverse Stock Split, have been computed as follows: For the Years Ended December 31, 2016 2015 2014 (dollars in thousands, except per share data) Net income available to common stockholders $ $ $ Shares: Weighted average common shares outstanding Dilutive effect of outstanding options, warrants and restricted stock units as determined by the application of the treasury stock method Weighted average common shares outstanding, as adjusted for diluted earnings per share calculation Basic earnings per common share $ $ $ Diluted earnings per common share $ $ $ Reclassifications Reclassifications have been made to certain prior year account balances, with no effect on net income or stockholders’ equity, to be consistent with the classifications adopted as of and for the year ended December 31, 2016. Subsequent events The Company has evaluated subsequent events for potential recognition and/or disclosure through the date the Consolidated Financial Statements included in this Annual Report on Form 10-K were issued. On February 6, 2017, First Busey announced entering into a Merger Agreement with First Community, pursuant to which First Community will merge into Frist Busey. The Merger is anticipated to be completed in mid-2017, and is subject to the satisfaction of customary closing conditions contained in the Merger Agreement including the approval of the appropriate regulatory authorities and the stockholders of First Community. See “ Note 2. Acquisitions ” for further information relating to this planned acquisition. Other than the Merger Agreement with First Community, there were no significant subsequent events for the year ended December 31, 2016 through the filing date of these Consolidated Financial Statements.
