Accounting Policies [Abstract]
Accounting Policies	Note 1 - Accounting Policies The accompanying unaudited condensed consolidated financial statements include the accounts of Horizon Bancorp (“Horizon” or the “Company”) and its wholly-owned subsidiaries, including Horizon Bank (“Horizon Bank” or the “Bank”). Horizon Bank (formerly known as “Horizon Bank, N.A.”) was a national association until its conversion to an Indiana commercial bank effective June 23, 2017. All inter-company balances and transactions have been eliminated. The results of operations for the periods ended March 31, 2018 and March 31, 2017 are not necessarily indicative of the operating results for the full year of 2018 or 2017. The accompanying unaudited condensed consolidated financial statements reflect all adjustments that are, in the opinion of Horizon’s management, necessary to fairly present the financial position, results of operations and cash flows of Horizon for the periods presented. Those adjustments consist only of normal recurring adjustments. Certain information and note disclosures normally included in Horizon’s annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in Horizon’s Annual Report on Form 10-K Basic earnings per share is computed by dividing net income available to common shareholders (net income less dividend requirements for preferred stock and accretion of preferred stock discount) by the weighted-average number of common shares outstanding. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. The following table shows computation of basic and diluted earnings per share. Three Months Ended March 31 2018 2017 Basic earnings per share Net income $ 12,804 $ 8,224 Weighted average common shares outstanding 25,537,597 22,175,526 Basic earnings per share $ 0.50 $ 0.37 Diluted earnings per share Net income available to common shareholders $ 12,804 $ 8,224 Weighted average common shares outstanding 25,537,597 22,175,526 Effect of dilutive securities: Restricted stock 23,571 36,336 Stock options 84,706 114,209 Weighted average common shares outstanding 25,645,874 22,326,071 $ 0.50 $ 0.37 There were 44,053 and zero shares for the three months ended March 31, 2018 and 2017, respectively, that were not included in the computation of diluted earnings per share because they were non-dilutive. Horizon has share-based employee compensation plans, which are described in the notes to the financial statements included in the December 31, 2017 Annual Report on Form 10-K. Adoption of New Accounting Standards Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) No. 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income The FASB has issued ASU No. 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income 2018-02 FASB ASU No. 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities The FASB has issued ASU No. 2016-01, Financial Instruments – Overall (Subtopic 825-10): not-for-profit The new guidance makes targeted improvements to existing U.S. GAAP by: • Requiring equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; • Requiring public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; • Requiring separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements; • Eliminating the requirement to disclose the fair value of financial instruments measured at amortized cost for organizations that are not public business entities; • Eliminating the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; and • Requiring a reporting organization to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk (also referred to as “own credit”) when the organization has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. The new guidance is effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The new guidance permits early adoption of the own credit provision. In addition, the new guidance permits early adoption of the provision that exempts private companies and not-for-profit 2016-01 FASB ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) The FASB has issued ASU No. 2014-09 Revenue from Contracts with Customers (Topic 606). 2014-09 In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients In December 2016, the FASB issued ASU No. 2016-20, Revenue from Contracts with Customers (Topic 606): Technical Corrections and Improvements No. 2014-09 No. 2014-09. No. 2014-09. Revenue Recognition Accounting Standards Codification 606, “ Revenue from Contracts with Customers” • Service charges and fees on deposit accounts – these include general service fees charged for deposit account maintenance and activity and transaction-based fees charged for certain services, such as debit card, wire transfer or overdraft activities. Revenue is recognized when the performance obligation is completed, which is generally after a transaction is completed or monthly for account maintenance services. • Fiduciary activities – this includes periodic fees due from trust and wealth management customers for managing the customers’ financial assets. Fees are charged based on a standard agreement and are recognized as they are earned. Reclassifications Certain reclassifications have been made to the 2017 condensed consolidated financial statements to be comparable to 2018. These reclassifications had no effect on net income.

Acquisitions	Note 2 – Acquisitions Wolverine Bancorp, Inc. On October 17, 2017, Horizon completed the acquisition of Wolverine Bancorp, Inc., a Maryland corporation (“Wolverine”) and Horizon Bank’s acquisition of Wolverine Bank, a federally chartered savings bank and wholly-owned subsidiary of Wolverine, through mergers effective October 17, 2017. Under the terms of the Merger Agreement, shareholders of Wolverine received 1.0152 shares of Horizon common stock and $14.00 in cash for each outstanding share of Wolverine common stock. Wolverine shares outstanding at the closing to be exchanged were 2,129,331, and the shares of Horizon common stock issued to Wolverine shareholders totaled 2,160,697. Based upon the October 16, 2017 closing price of $29.06 per share of Horizon common stock immediately prior to the effectiveness of the merger, less the consideration used to pay off Wolverine Bancorp’s ESOP loan receivable, the transaction has an implied valuation of approximately $93.8 million. The Company incurred approximately $1.9 million in costs related to the acquisition. These expenses are classified in the non-interest Under the acquisition method of accounting, the total purchase price is allocated to net tangible and intangible assets based on their current estimated fair values on the date of the acquisition. Based on preliminary valuations of the fair value of tangible and intangible assets acquired and liabilities assumed, which are based on estimates and assumptions that are subject to change, the final purchase price for the Wolverine acquisition is allocated as follows: Assets Liabilities Cash and due from banks $ 44,450 Deposits Non-interest $ 25,221 Loans NOW accounts 8,026 Commercial 276,167 Savings and money market 129,044 Residential mortgage 30,603 Certificates of deposit 94,688 Consumer 3,897 Total deposits 256,979 Total loans 310,667 Premises and equipment, net 2,941 Borrowings 36,970 FRB and FHLB stock 2,700 Interest payable 214 Goodwill 26,827 Other liabilities 6,154 Core deposit intangible 2,024 Interest receivable 584 Other assets 3,897 Total assets purchased $ 394,090 Total liabilities assumed $ 300,317 Common shares issued $ 62,111 Cash paid 31,662 Total estimated purchase price $ 93,773 Of the total purchase price of $93.8 million, $2.0 million has been allocated to core deposit intangible. Additionally, $26.8 million has been allocated to goodwill and none of the purchase price is deductible. The core deposit intangible is being amortized over 10 years on a straight line basis. The Company acquired various loans in the acquisition that had evidence of deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected. Loans purchased with evidence of credit deterioration since origination and for which it is probable that all contractually required payments will not be collected are considered to be credit impaired. Evidence of credit quality deterioration as of the purchase date may include information such as past-due non-accrual loan-to-value 310-30) The following table details the acquired loans that are accounted for in accordance with ASC 310-30 Contractually required principal and interest at acquisition $ 21,912 Contractual cash flows not expected to be collected (nonaccretable differences) 1,832 Expected cash flows at acquisition 20,080 Interest component of expected cash flows (accretable discount) 2,267 Fair value of acquired loans accounted for under ASC 310-30 $ 17,813 Final estimates of certain loans, those for which specific credit-related deterioration, since origination, are recorded at fair value, reflecting the present value of the amounts expected to be collected. Income recognition of these loans is based on reasonable expectation about the timing and amount of cash flows to be collected. Lafayette Community Bancorp On September 1, 2017, Horizon completed the acquisition of Lafayette Community Bancorp, an Indiana corporation (“Lafayette”) and Horizon Bank’s acquisition of Lafayette Community Bank, a state-chartered bank and wholly-owned subsidiary of Lafayette, through mergers effective September 1, 2017. Under the terms of the Merger Agreement, shareholders of Lafayette received 0.5878 shares of Horizon common stock and $1.73 in cash for each outstanding share of Lafayette common stock. Lafayette shareholders owning fewer than 100 shares of common stock received $17.25 in cash for each common share. Lafayette shares outstanding at the closing to be exchanged were 1,856,679, and the shares of Horizon common stock issued to Lafayette shareholders totaled 1,091,259. Based upon the August 31, 2017 closing price of $26.17 per share of Horizon common stock immediately prior to the effectiveness of the merger, the transaction has an implied valuation of approximately $34.5 million. The Company incurred approximately $1.7 million in costs related to the acquisition. These expenses are classified in the non-interest Horizon held 5% ownership in Lafayette immediately preceding the merger date. In accordance with ASC 805-10 Under the acquisition method of accounting, the total purchase price is allocated to net tangible and intangible assets based on their current estimated fair values on the date of the acquisition. Based on preliminary valuations of the fair value of tangible and intangible assets acquired and liabilities assumed, which are based on assumptions that are subject to change, the purchase price for the Lafayette acquisition is detailed in the following table. Assets Liabilities Cash and due from banks $ 24,846 Deposits Investment securities, available for sale 6 Non-interest $ 34,990 NOW accounts 30,174 Loans Savings and money market 53,663 Commercial 116,258 Certificates of deposit 32,520 Residential mortgage 12,761 Total deposits 151,347 Consumer 5,280 Total loans 134,299 Premises and equipment, net 7,818 Interest payable 42 FHLB stock 395 Other liabilities 990 Goodwill 15,408 Core deposit intangible 2,085 Interest receivable 338 Other assets 1,649 Total assets purchased $ 186,844 Total liabilities assumed $ 152,379 Common shares issued $ 30,044 (1) Cash paid 4,421 Total estimated purchase price $ 34,465 (1) This includes $955,000 of common shares previously held by Horizon. Of the total estimated purchase price of $34.5 million, $2.1 million has been allocated to core deposit intangible. Additionally, $15.4 million has been allocated to goodwill and none of the purchase price is deductible. The core deposit intangible will be amortized over 10 years on a straight-line basis. The Company acquired various loans in the acquisition that had evidence of deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected. Loans purchased with evidence of credit deterioration since origination and for which it is probable that all contractually required payments will not be collected are considered to be credit impaired.

While these securities are held in the available for sale portfolio and held-to-maturity, Should the impairment of any of these securities become other than temporary, the cost basis of the investment will be reduced and the resulting loss recognized in net income in the period the other-than-temporary impairment is identified. At March 31, 2018, no individual investment security had an unrealized loss that was determined to be other-than-temporary. The unrealized losses on the Company’s investments in securities of state and municipal governmental agencies, U.S. Treasury and federal agencies, federal agency collateralized mortgage obligations, and federal agency mortgage-backed pools were caused by interest rate volatility and not a decline in credit quality. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. The Company expects to recover the amortized cost basis over the term of the securities. Because the Company does not intend to sell the investments and it is not likely that the Company will be required to sell the investments before recovery of their amortized cost basis, which may be at maturity, the Company did not consider those investments to be other-than-temporarily impaired at March 31, 2018. The amortized cost and fair value of securities available for sale and held to maturity at March 31, 2018 and December 31, 2017, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

The cash flows of borrowers, however, may not be as expected, and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some short-term loans may be made on an unsecured basis. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers. Commercial real estate loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves larger loan principal amounts and the repayment of these loans is generally dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Commercial real estate loans may be more adversely affected by conditions in the real estate markets, the general economy or fluctuations in interest rates. The properties securing the Company’s commercial real estate portfolio are diverse in terms of property type, and are monitored for concentrations of credit. Management monitors and evaluates commercial real estate loans based on collateral, cash flow and risk grade criteria. As a general rule, the Company avoids financing single purpose projects unless other underwriting factors are present to help mitigate risk. In addition, management tracks the level of owner-occupied commercial real estate loans versus non-owner Real Estate and Consumer With respect to residential loans that are secured by 1-4 loan-to-value 1-4 Mortgage Warehousing Horizon’s mortgage warehouse lending has specific mortgage companies as customers of Horizon Bank. Individual mortgage loans originated by these mortgage companies are funded as a secured borrowing with a pledge of collateral under Horizon’s agreement with the mortgage company. Each mortgage loan funded by Horizon undergoes an underwriting review by Horizon to the end investor guidelines and is assigned to Horizon until the loan is sold to the secondary market by the mortgage company. In addition, Horizon takes possession of each original note and forwards such note to the end investor once the mortgage company has sold the loan. At the time a loan is transferred to the secondary market, the mortgage company reacquires the loan under its option within the agreement. Due to the reacquire feature contained in the agreement, the transaction does not qualify as a sale and therefore is accounted for as a secured borrowing with a pledge of collateral pursuant to the agreement with the mortgage company. When the individual loan is sold to the end investor by the mortgage company, the proceeds from the sale of the loan are received by Horizon and used to pay off the loan balance with Horizon along with any accrued interest and any related fees. The remaining balance from the sale is forwarded to the mortgage company. These individual loans typically are sold by the mortgage company within 30 days and are seldom held more than 90 days. Interest income is accrued during this period and collected at the time each loan is sold. Fee income for each loan sold is collected when the loan is sold, and no costs are deferred due to the term between each loan funding and related payoff, which is typically less than 30 days. Based on the agreements with each mortgage company, at any time a mortgage company can reacquire from Horizon its outstanding loan balance on an individual mortgage and regain possession of the original note. Horizon also has the option to request that the mortgage company reacquire an individual mortgage. Should this occur, Horizon would return the original note and reassign the assignment of the mortgage to the mortgage company. Also, in the event that the end investor would not be able to honor the purchase commitment and the mortgage company would not be able to reacquire its loan on an individual mortgage, Horizon would be able to exercise its rights under the agreement. The following table shows the recorded investment of individual loan categories.

Allowance for Loan Losses	Note 6 – Allowance for Loan Losses The historical loss experience is determined by portfolio segment and is based on the actual loss history experienced by the Company over the prior one to five years. Management believes using the highest of the one, two or five-year historical loss experience is an appropriate methodology in the current economic environment, as it captures loss rates that are comparable to the current period being analyzed.

In recognition of this, it is management’s policy to convert the loan from an “earning asset” to a non-accruing non-accrual non-accrual non-accrual Non-accrual non-accrual A loan becomes impaired when, based on current information, it is probable that a creditor will be unable to collect all amounts due according to the contractual terms of the loan agreement. When a loan is classified as impaired, the degree of impairment must be recognized by estimating future cash flows from the debtor. The present value of these cash flows is computed at a discount rate based on the interest rate contained in the loan agreement. However, if a particular loan has a determinable market value for its collateral, the creditor may use that value. Also, if the loan is secured and considered collateral dependent, the creditor may use the fair value of the collateral. Interest income on loans individually classified as impaired is recognized on a cash basis after all past due and current principal payments have been made. Smaller-balance, homogeneous loans are evaluated for impairment in total. Such loans include residential first mortgage loans secured by 1–4 family residences, residential construction loans, automobile, home equity, second mortgage loans and mortgage warehouse loans. Commercial loans and mortgage loans secured by other properties are evaluated individually for impairment. When analysis of borrower operating results and financial condition indicate that underlying cash flows of a borrower’s business are not adequate to meet its debt service requirements, the loan is evaluated for impairment. Often this is associated with a delay or shortfall in payments of 30 days or more. Loans are generally moved to non-accrual Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms, including TDRs, are measured for impairment. Allowable methods for determining the amount of impairment include the three methods described above. The Company’s TDRs are considered impaired loans and included in the allowance methodology using the guidance for impaired loans. At March 31, 2018, the type of concessions the Company has made on restructured loans has been temporary rate reductions and/or reductions in monthly payments and there have been no restructured loans with modified recorded balances. Any modification to a loan that is a concession and is not in the normal course of lending is considered a restructured loan. A restructured loan is returned to accruing status after six consecutive payments but is still reported as TDR unless the loan bears interest at a market rate. As of March 31, 2018, the Company had $3.0 million in TDRs and $1.1 million were performing according to the restructured terms and $0 in TDRs were returned to accrual status during the first three months of 2018. There were $70,000 specific reserves allocated to TDRs at March 31, 2018 based on the discounted cash flows or when appropriate the fair value of the collateral.

Horizon Bank’s processes for determining credit quality differ slightly depending on whether a new loan or a renewed loan is being underwritten, or whether an existing loan is being re-evaluated • For new and renewed commercial loans, the Bank’s Credit Department, which acts independently of the loan officer, assigns the credit quality grade to the loan. Loan grades for loans with an aggregate credit exposure that exceeds the authorities in the respective markets (ranging from $1,000,000 to $3,500,000) are validated by the Loan Committee, which is chaired by the Chief Commercial Banking Officer (CCBO). • Commercial loan officers are responsible for reviewing their loan portfolios and report any adverse material change to the CCBO or Loan Committee. When circumstances warrant a change in the credit quality grade, loan officers are required to notify the CCBO and the Credit Department of the change in the loan grade. Downgrades are accepted immediately by the CCBO, however, lenders must present their factual information to either the Loan Committee or the CCBO when recommending an upgrade. • The CCBO, or his designee, meets weekly with loan officers to discuss the status of past-due • Monthly, senior management meets with the Watch Committee, which reviews all of the past due, classified, and impaired loans and the relative trends of these assets. This committee also reviews the actions taken by management regarding foreclosure mitigation, loan extensions, troubled debt restructures, other real estate owned and personal property repossessions. The information reviewed in this meeting acts as a precursor for developing management’s analysis of the adequacy of the Allowance for Loan and Lease Losses. For residential real estate and consumer loans, Horizon uses a grading system based on delinquency. Loans that are 90 days or more past due, on non-accrual, non-accrual. Horizon Bank employs a nine-grade rating system to determine the credit quality of commercial loans. The first five grades represent acceptable quality, and the last four grades mirror the criticized and classified grades used by the bank regulatory agencies (special mention, substandard, doubtful, and loss). The loan grade definitions are detailed below. Risk Grade 1: Excellent (Pass) Loans secured by liquid collateral, such as certificates of deposit, reputable bank letters of credit, or other cash equivalents; loans that are guaranteed or otherwise backed by the full faith and credit of the United States government or an agency thereof, such as the Small Business Administration; or loans to any publicly held company with a current long-term debt rating of A or better. Risk Grade 2: Good (Pass) Loans to businesses that have strong financial statements containing an unqualified opinion from a CPA firm and at least three consecutive years of profits; loans supported by unaudited financial statements containing strong balance sheets, five consecutive years of profits, a five-year satisfactory relationship with the Bank, and key balance sheet and income statement trends that are either stable or positive; loans secured by publicly traded marketable securities where there is no impediment to liquidation; loans to individuals backed by liquid personal assets and unblemished credit history; or loans to publicly held companies with current long-term debt ratings of Baa or better. Risk Grade 3: Satisfactory (Pass) Loans supported by financial statements (audited or unaudited) that indicate average or slightly below average risk and having some deficiency or vulnerability to changing economic conditions; loans with some weakness but offsetting features of other support are readily available; loans that are meeting the terms of repayment, but which may be susceptible to deterioration if adverse factors are encountered. Loans may be graded Satisfactory when there is no recent information on which to base a current risk evaluation and the following conditions apply: • At inception, the loan was properly underwritten, did not • At inception, the loan was secured with collateral possessing a loan value adequate to protect the Bank from loss. • The loan has exhibited two or more years of satisfactory repayment with a reasonable reduction of the principal balance. • During the period that the loan has been outstanding, there has been no evidence of any credit weakness. Some examples of weakness include slow payment, lack of cooperation by the borrower, breach of loan covenants, or the borrower is in an industry known to be experiencing problems. If any of these credit weaknesses is observed, a lower risk grade may be warranted. Risk Grade 4 Satisfactory/Monitored: Loans in this category are considered to be of acceptable credit quality, but contain greater credit risk than Satisfactory loans. Borrower displays acceptable liquidity, leverage, and earnings performance within the Bank’s minimum underwriting guidelines. The level of risk is acceptable but conditioned on the proper level of loan officer supervision. Loans that normally fall into this grade include acquisition, construction and development loans and income producing properties that have not reached stabilization. Risk Grade 4W Management Watch: Loans in this category are considered to be of acceptable quality, but with above normal risk. Borrower displays potential indicators of weakness in the primary source of repayment resulting in a higher reliance on secondary sources of repayment. Balance sheet may exhibit weak liquidity and/or high leverage. There is inconsistent earnings performance without the ability to sustain adverse economic conditions. Borrower may be operating in a declining industry or the property type, as for a commercial real estate loan, may be high risk or in decline. These loans require an increased level of loan officer supervision and monitoring to assure that any deterioration is addressed in a timely fashion. Risk Grade 5: Special Mention Loans which possess some credit deficiency or potential weakness which deserves close attention. Such loans pose an unwarranted financial risk that, if not corrected, could weaken the loan by adversely impacting the future repayment ability of the borrower. The key distinctions of a Special Mention classification are that (1) it is indicative of an unwarranted level of risk and (2) weaknesses are considered “potential,” not “defined,” impairments to the primary source of repayment. These loans may be to borrowers with adverse trends in financial performance, collateral value and/or marketability, or balance sheet strength. Risk Grade 6: Substandard One or more of the following characteristics may be exhibited in loans classified Substandard: • Loans which possess a defined credit weakness. The likelihood that a loan will be paid from the primary source of repayment is uncertain. Financial deterioration is under way and very close attention is warranted to ensure that the loan is collected without loss. • Loans are inadequately protected by the current net worth and paying capacity of the obligor. • The primary source of repayment is gone, and the Bank is forced to rely on a secondary source of repayment, such as collateral liquidation or guarantees. • Loans have a distinct possibility that the Bank will sustain some loss if deficiencies are not corrected. • Unusual courses of action are needed to maintain a high probability of repayment. • The borrower is not generating enough cash flow to repay loan principal; however, it continues to make interest payments. • The lender is forced into a subordinated or unsecured position due to flaws in documentation. • Loans have been restructured so that payment schedules, terms, and collateral represent concessions to the borrower when compared to the normal loan terms. • The lender is seriously contemplating foreclosure or legal action due to the apparent deterioration in the loan. • There is a significant deterioration in market conditions to which the borrower is highly vulnerable. Risk Grade 7: Doubtful One or more of the following characteristics may be present in loans classified Doubtful: • Loans have all of the weaknesses of those classified as Substandard. However, based on existing conditions, these weaknesses make full collection of principal highly improbable. • The primary source of repayment is gone, and there is considerable doubt as to the quality of the secondary source of repayment. • The possibility of loss is high but because of certain important pending factors which may strengthen the loan, loss classification is deferred until the exact status of repayment is known. Risk Grade 8: Loss Loans are considered uncollectible and of such little value that continuing to carry them as assets is not feasible. Loans will be classified Loss when it is neither practical nor desirable to defer writing off or reserving all or a portion of a basically worthless asset, even though partial recovery may be possible at some time in the future.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Note 9 – Derivative Financial Instruments Cash Flow Hedges As a strategy to maintain acceptable levels of exposure to the risk of changes in future cash flow due to interest rate fluctuations, the Company entered into interest rate swap agreements for a portion of its floating rate debt. The agreements provide for the Company to receive interest from the counterparty at three month LIBOR and to pay interest to the counterparty at a weighted average fixed rate of 5.81% on a notional amount of $30.5 million at March 31, 2018 and December 31, 2017. Under the agreements, the Company pays or receives the net interest amount monthly, with the monthly settlements included in interest expense. The Company assumed additional interest rate swap agreements as the result of the LaPorte acquisition in July 2016. The agreements provide for the Company to receive interest from the counterparty at one month LIBOR and to pay interest to the counterparty at a weighted average fixed rate of 2.31% on a notional amount of $30.0 million at March 31, 2018 and December 31, 2017. Under the agreements, the Company pays or receives the net interest amount monthly, with the monthly settlements included in interest expense. Management has designated the interest rate swap agreement as a cash flow hedging instrument. For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. At March 31, 2018, the Company’s cash flow hedge was effective and is not expected to have a significant impact on the Company’s net income over the next 12 months. Fair Value Hedges Fair value hedges are intended to reduce the interest rate risk associated with the underlying hedged item. The Company enters into fixed rate loan agreements as part of its lending policy. To mitigate the risk of changes in fair value based on fluctuations in interest rates, the Company has entered into interest rate swap agreements on individual loans, converting the fixed rate loans to a variable rate. For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative as well as the offsetting gain or loss on the hedged item attributable to the hedged risk are recognized in current earnings. At March 31, 2018, the Company’s fair value hedges were effective and are not expected to have a significant impact on the Company’s net income over the next 12 months. The change in fair value of both the hedge instruments and the underlying loan agreements are recorded as gains or losses in interest income. The fair value hedges are considered to be highly effective and any hedge ineffectiveness was deemed not material. The notional amounts of the loan agreements being hedged were $155.0 million at March 31, 2018 and $154.6 million at December 31, 2017. Other Derivative Instruments The Company enters into non-hedging The change in fair value of both the forward sale commitments and commitments to originate mortgage loans were recorded and the net gains or losses included in the Company’s gain on sale of loans.

Disclosures about Fair Value of Assets and Liabilities	Note 10 – Disclosures about Fair Value of Assets and Liabilities The Fair Value Measurements topic of the FASB ASC defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. There are three levels of inputs that may be used to measure fair value: Level 1 Quoted prices in active markets for identical assets or liabilities Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities Following is a description of the valuation methodologies used for instruments measured at fair value on a recurring basis and recognized in the accompanying condensed consolidated financial statements, as well as the general classification of such instruments pursuant to the valuation hierarchy. There have been no significant changes in the valuation techniques during the period ended March 31, 2018. For assets classified within Level 3 of the fair value hierarchy, the process used to develop the reported fair value is described below. Available for sale securities When quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. Level 2 securities include U.S. Treasury and federal agency securities, state and municipal securities, federal agency collateralized mortgage obligations and mortgage-backed pools and corporate notes. Level 2 securities are valued by a third party pricing service commonly used in the banking industry utilizing observable inputs. Observable inputs include dealer quotes, market spreads, cash flow analysis, the U.S. Treasury yield curve, trade execution data, market consensus prepayment spreads and available credit information and the bond’s terms and conditions. The pricing provider utilizes evaluated pricing models that vary based on asset class. These models incorporate available market information including quoted prices of securities with similar characteristics and, because many fixed-income securities do not trade on a daily basis, apply available information through processes such as benchmark curves, benchmarking of like securities, sector grouping, and matrix pricing. In addition, model processes, such as an option adjusted spread model, is used to develop prepayment and interest rate scenarios for securities with prepayment features. Hedged loans Certain fixed rate loans have been converted to variable rate loans by entering into interest rate swap agreements. The fair value of those fixed rate loans is based on discounting the estimated cash flows using interest rates determined by the respective interest rate swap agreement. Loans are classified within Level 2 of the valuation hierarchy based on the unobservable inputs used. Interest rate swap agreements The fair value of the Company’s interest rate swap agreements is estimated by a third party using inputs that are primarily unobservable including a yield curve, adjusted for liquidity and credit risk, contracted terms and discounted cash flow analysis, and therefore, are classified within Level 2 of the valuation hierarchy. The following table presents the fair value measurements of assets and liabilities recognized in the accompanying condensed consolidated financial statements measured at fair value on a recurring basis and the level within the FASB ASC fair value hierarchy in which the fair value measurements fall at the following: March 31, 2018 Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Available for sale securities U.S. Treasury and federal agencies $ 24,284 $ — $ 24,284 $ — State and municipal 133,371 — 133,371 — Federal agency collateralized mortgage obligations 133,408 — 133,408 — Federal agency mortgage-backed pools 212,173 — 212,173 — Private labeled mortgage-backed pools 4,110 — 4,110 — Corporate notes 390 — 390 — Total available for sale securities 507,736 — 507,736 — Hedged loans 155,013 — 155,013 — Forward sale commitments 257 — 257 — Interest rate swap agreements 2,610 — 2,610 — Commitments to originate loans (4 ) — (4 ) — December 31, 2017 Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Available for sale securities U.S. Treasury and federal agencies $ 19,052 $ — $ 19,052 $ — State and municipal 149,564 — 149,564 — Federal agency collateralized mortgage obligations 130,365 — 130,365 — Federal agency mortgage-backed pools 208,657 — 208,657 — Private labeled mortgage-backed pools 1,642 — 1,642 — Corporate notes 385 — 385 — Total available for sale securities 509,665 — 509,665 — Hedged loans 154,575 — 154,575 — Forward sale commitments 143 — 143 — Interest rate swap agreements (917 ) — (917 ) — Commitments to originate loans (3 ) — (3 ) — Realized gains and losses included in net income for the periods are reported in the condensed consolidated statements of income as follows: Three Months Ended March 31, 2018 March 31, 2017 (Unaudited) (Unaudited) Non-interest Total gains and losses from: Hedged loans $ 2,768 $ 253 Fair value interest rate swap agreements (2,768 ) (253 ) Derivative loan commitments 112 (59 ) $ 112 $ (59 ) Certain other assets are measured at fair value on a non-recurring Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) March 31, 2018 Impaired loans $ 6,593 $ — $ — $ 6,593 Mortgage servicing rights 11,477 — — 11,477 December 31, 2017 Impaired loans $ 6,957 $ — $ — $ 6,957 Mortgage servicing rights 11,602 — — 11,602 Impaired (collateral dependent): If the impaired loan is identified as collateral dependent, then the fair value method of measuring the amount of impairment is utilized.

Impaired loans that are collateral dependent are classified within Level 3 of the fair value hierarchy when impairment is determined using the fair value method.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 11 – Fair Value of Financial Instruments The estimated fair value amounts of the Company’s financial instruments were determined using available market information, current pricing information applicable to Horizon and various valuation methodologies. Where market quotations were not available, considerable management judgment was involved in the determination of estimated fair values. Therefore, the estimated fair value of financial instruments shown below may not be representative of the amounts at which they could be exchanged in a current or future transaction. Due to the inherent uncertainties of expected cash flows of financial instruments, the use of alternate valuation assumptions and methods could have a significant effect on the estimated fair value amounts. The estimated fair values of financial instruments, as shown below, are not intended to reflect the estimated liquidation or market value of Horizon taken as a whole. The disclosed fair value estimates are limited to Horizon’s significant financial instruments at March 31, 2018 and December 31, 2017. These include financial instruments recognized as assets and liabilities on the condensed consolidated balance sheet as well as certain off-balance The following methods and assumptions were used to estimate the fair value of each class of financial instrument: Cash and Due from Banks Held-to-Maturity Loans Held for Sale Net Loans FHLB and FRB Stock Interest Receivable/Payable Deposits Borrowings Subordinated Debentures Commitments to Extend Credit and Standby Letters of Credit The following table presents estimated fair values of the Company’s financial instruments and the level within the fair value hierarchy in which the fair value measurements fall (unaudited).

Banking and Thrift [Abstract]
Regulatory Capital	Note 13 – Regulatory Capital Horizon and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies and are assigned to a capital category. Failure to meet the minimum regulatory capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators, which if undertaken, could have a direct material effect on the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective actions, the Bank must meet specific capital guidelines involving quantitative measures of the Bank’s assets, liabilities, and certain off-balance-sheet Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios of total and Tier I capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier I capital (as defined) to average assets (as defined), or leverage ratio. For March 31, 2018, Basel III rules require the Bank to maintain minimum amounts and ratios of common equity Tier I capital (as defined in the regulation) to risk-weighted assets (as defined). Additionally, under Basel III rules, the decision was made to opt-out To be categorized as well capitalized, the Bank must maintain minimum Total risk-based, Tier I risk-based, common equity Tier I risk-based and Tier I leverage ratios as set forth in the table below. As of March 31, 2018 and December 31, 2017, the Bank met all capital adequacy requirements to be considered well capitalized. There have been no conditions or events since the end of the first quarter of 2018 that management believes have changed the Bank’s classification as well capitalized. There is no threshold for well-capitalized status for bank holding companies. Horizon and the Bank’s actual and required capital ratios as of March 31, 2018 and December 31, 2017 were as follows: Actual Required for Capital 1 Adequacy Purposes Required For Capital 1 Adequacy Purposes with Capital Buffer Well Capitalized Under 1 Corrective Action Amount Ratio Amount Ratio Amount Ratio Amount Ratio March 31, 2018 Total capital 1 Consolidated $ 390,855 13.08 % 239,082 8.00 % 276,439 9.25 % N/A N/A Bank 384,766 12.87 % 239,093 8.00 % 276,451 9.25 % $ 298,866 10.00 % Tier 1 capital 1 Consolidated 374,322 12.53 % 179,312 6.00 % 216,668 7.25 % N/A N/A Bank 368,233 12.32 % 179,320 6.00 % 216,678 7.25 % 239,093 8.00 % Common equity tier 1 capital 1 Consolidated 335,859 11.24 % 134,483 4.50 % 171,840 5.75 % N/A N/A Bank 368,233 12.32 % 134,490 4.50 % 171,848 5.75 % 194,263 6.50 % Tier 1 capital 1 Consolidated 374,322 9.82 % 152,494 4.00 % 152,494 4.00 % N/A N/A Bank 368,233 9.66 % 152,542 4.00 % 152,542 4.00 % 190,678 5.00 % December 31, 2017 Total capital 1 Consolidated $ 384,800 12.91 % $ 238,543 8.00 % $ 275,816 9.25 % N/A N/A Bank 382,788 12.85 % 238,386 8.00 % 275,634 9.25 % $ 297,982 10.00 % Tier 1 capital 1 Consolidated 368,355 12.35 % 178,907 6.00 % 216,180 7.25 % N/A N/A Bank 366,343 12.29 % 178,790 6.00 % 216,038 7.25 % 238,386 8.00 % Common equity tier 1 capital 1 Consolidated 329,892 11.06 % 134,181 4.50 % 171,454 5.75 % N/A N/A Bank 366,343 12.29 % 134,092 4.50 % 171,340 5.75 % 193,689 6.50 % Tier 1 capital 1 Consolidated 368,355 9.92 % 148,503 4.00 % 148,503 4.00 % N/A N/A Bank 366,343 9.89 % 148,116 4.00 % 148,116 4.00 % 185,145 5.00 %

Earnings Per Share	Basic earnings per share is computed by dividing net income available to common shareholders (net income less dividend requirements for preferred stock and accretion of preferred stock discount) by the weighted-average number of common shares outstanding. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. The following table shows computation of basic and diluted earnings per share. Three Months Ended March 31 2018 2017 Basic earnings per share Net income $ 12,804 $ 8,224 Weighted average common shares outstanding 25,537,597 22,175,526 Basic earnings per share $ 0.50 $ 0.37 Diluted earnings per share Net income available to common shareholders $ 12,804 $ 8,224 Weighted average common shares outstanding 25,537,597 22,175,526 Effect of dilutive securities: Restricted stock 23,571 36,336 Stock options 84,706 114,209 Weighted average common shares outstanding 25,645,874 22,326,071 $ 0.50 $ 0.37 There were 44,053 and zero shares for the three months ended March 31, 2018 and 2017, respectively, that were not included in the computation of diluted earnings per share because they were non-dilutive.

The new guidance is effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The new guidance permits early adoption of the own credit provision.
