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, N.A. (“Bank”). All inter-company balances and transactions have been eliminated. The results of operations for the periods ended March 31, 2016 and March 31, 2015 are not necessarily indicative of the operating results for the full year of 2016 or 2015. 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 2016 2015 (Unaudited) (Unaudited) Basic earnings per share Net income $ 5,381 $ 5,358 Less: Preferred stock dividends 42 31 Net income available to common shareholders $ 5,339 $ 5,327 Weighted average common shares outstanding 11,949,416 9,216,011 Basic earnings per share $ 0.45 $ 0.58 Diluted earnings per share Net income available to common shareholders $ 5,339 $ 5,327 Weighted average common shares outstanding 11,949,416 9,216,011 Effect of dilutive securities: Warrants — 321,652 Restricted stock 21,033 30,510 Stock options 38,035 41,333 Weighted average shares outstanding 12,008,484 9,609,506 Diluted earnings per share $ 0.44 $ 0.55 There were zero dilutive shares for the three months ended March 31, 2016 and 62,445 shares for the three months ended March 31, 2015 which 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, 2015 Annual Report on Form 10-K. Reclassifications Certain reclassifications have been made to the 2015 condensed consolidated financial statements to be comparable to 2016. These reclassifications had no effect on net income.

Acquisitions

Acquisitions	3 Months Ended

Business Combinations [Abstract]
Acquisitions	Note 2 – Acquisitions On July 1, 2015, Horizon completed the acquisition of Peoples Bancorp, an Indiana corporation (“Peoples”) and Horizon Bank N.A.’s acquisition of Peoples Federal Savings Bank of DeKalb County (“Peoples FSB”), through mergers effective July 1, 2015. Under the terms of the acquisition, the exchange ratio was 0.95 shares of Horizon common stock (the “Exchange Ratio”) and $9.75 in cash for each outstanding share of Peoples common stock. Peoples shareholders owning fewer than 100 shares of common stock received $33.14 in cash for each common share. Peoples shares outstanding at the closing were 2,311,858, and the shares of Horizon common stock issued to Peoples shareholders totaled 2,192,202. Horizon’s stock price was $25.32 per share at the close of business on July 1, 2015. Based upon these numbers, the total value of the consideration for the acquisition was $78.1 million. The Company had approximately $4.9 million in costs related to the acquisition as of December 31, 2015. These expenses were classified in the other expense section of the income statement and primarily located in the salaries and employee benefits, professional services and other expense line items. As a result of the acquisition, the Company will have an opportunity to increase its deposit base and reduce transaction costs. The Company also expects to reduce cost through economies of scale. Under the purchase method of accounting, the total estimated purchase price is allocated to Peoples net tangible and intangible assets based on their current estimated fair values on the date of the acquisition. Based on management’s preliminary valuation 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 Peoples acquisition is allocated as follows: ASSETS Cash and due from banks $ 205,054 Investment securities, held to maturity 2,038 Commercial 67,435 Residential mortgage 137,331 Consumer 19,593 Total loans 224,359 Premises and equipment, net 5,524 FRB and FHLB stock 2,743 Goodwill 21,424 Core deposit intangible 4,394 Interest receivable 1,279 Cash value of life insurance 13,898 Other assets 4,364 Total assets purchased $ 485,077 Common shares issued $ 55,506 Cash paid 22,641 Total estimated purchase price $ 78,147 LIABILITIES Deposits Non-interest bearing $ 28,251 NOW accounts 65,771 Savings and money market 125,176 Certificates of deposits 131,889 Total deposits 351,087 Borrowings 48,884 Interest payable 21 Other liabilities 6,938 Total liabilities assumed $ 406,930 Of the total purchase price of $78.1 million, $4.4 million has been allocated to core deposit intangible. Additionally, $21.0 million has been allocated to goodwill and none of the purchase price is deductible. The core deposit intangible will be amortized over seven years on a straight line basis. The Company acquired the $228.6 million loan portfolio at a fair value discount of $4.8 million. The performing portion of the portfolio, $223.4 million, had an estimated fair value of $220.0 million. The excess of expected cash flows above the fair value of the performing portion of loans will be accreted to interest income over the remaining lives of the loans in accordance with ASC 310-20. The Company acquired certain loans in the acquisition and the transferred loans had evidence of deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected. The 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 and non-accrual status, borrower credit scores and recent loan-to-value percentages. Purchased credit-impaired loans are accounted for under the accounting guidance for loans and debt securities acquired with deteriorated credit quality (ASC 310-30) and initially measured at fair value, which includes estimated future credit losses expected to be incurred over the life of the loan. Accordingly, an allowance for credit losses related to these loans is not carried over and recorded at the acquisition date. Management estimated the cash flows expected to be collected at acquisition using our internal risk models, which incorporate the estimate of current key assumptions, such as default rates, severity and prepayment speeds. Loans with 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. The following table details the acquired loans that are accounted for in accordance with ASC 310-30 as of July 1, 2015. Contractually required principal and interest at acquisition $ 5,730 Contractual cash flows not expected to be collected (nonaccretable differences) 715 Expected cash flows at acquisition 5,015 Interest component of expected cash flows (accretable discount) 647 Fair value of acquired loans accounted for under ASC 310-30 $ 4,368 The results of operations of Peoples and Peoples FSB have been included in the Company’s consolidated financial statements since the acquisition dates. The following schedule includes pro forma results for the periods ended March 31, 2016 and 2015 as if the Peoples and Peoples FSB acquisitions had occurred as of the beginning of the comparable prior reporting period. Three Months Ended March 31, March 31, 2016 2015 Summary of Operations: Net Interest Income $ 19,774 $ 19,865 Provision for Loan Losses 532 644 Net Interest Income after Provision for Loan Losses 19,242 19,221 Non-interest Income 7,864 7,966 Non-Interest Expense 19,747 19,270 Income before Income Taxes 7,359 7,917 Income Tax Expense 1,978 1,939 Net Income 5,381 5,978 Net Income Available to Common Shareholders $ 5,339 $ 5,984 Basic Earnings Per Share $ 0.45 $ 0.52 Diluted Earnings Per Share $ 0.44 $ 0.51 The pro forma information includes adjustments for interest income on loans, amortization of intangibles arising from the transaction, interest expense on deposits acquired, premises expense for the banking centers acquired and the related income tax effects. The pro forma information for the three months ended March 31, 2015 includes $657,000, net of tax, of operating revenue from Peoples and approximately $95,000, net of tax, of non-recurring expenses directly attributable to the Peoples acquisition. The pro forma financial information is presented for information purposes only and is not indicative of the results of operations that actually would have been achieved had the acquisition consummated as of that time, nor is it intended to be a projection of future results.

While these securities are held in the available for sale portfolio and held-to-maturity, Horizon intends, and has the ability, to hold them until the earlier of a recovery in fair value or 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, 2016, 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, 2016. The amortized cost and fair value of securities available for sale and held to maturity at March 31, 2016 and December 31, 2015, by contractual maturity, are shown below.

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 occupied loans. Real Estate and Consumer With respect to residential loans that are secured by 1-4 family residences and are generally owner occupied, the Company generally establishes a maximum loan-to-value ratio and requires private mortgage insurance if that ratio is exceeded. Home equity loans are typically secured by a subordinate interest in 1-4 family residences, and consumer loans are secured by consumer assets such as automobiles or recreational vehicles. Some consumer loans are unsecured such as small installment loans and certain lines of credit. Repayment of these loans is primarily dependent on the personal income of the borrowers, which can be impacted by economic conditions in their market areas such as unemployment levels. Repayment can also be impacted by changes in property values on residential properties. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over a large number of borrowers. 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 individual mortgage and the related mortgagee are underwritten 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 reaquire 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.

Accounting for Certain Loans Acquired in a Transfer	Note 5 – Accounting for Certain Loans Acquired in a Transfer The Company acquired loans in acquisitions and the transferred loans 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 and non-accrual status, borrower credit scores and recent loan-to-value percentages. Purchased credit-impaired loans are accounted for under the accounting guidance for loans and debt securities acquired with deteriorated credit quality (ASC 310-30) and initially measured at fair value, which includes estimated future credit losses expected to be incurred over the life of the loan. Accordingly, an allowance for credit losses related to these loans is not carried over and recorded at the acquisition date. Management estimated the cash flows expected to be collected at acquisition using our internal risk models, which incorporate the estimate of current key assumptions, such as default rates, severity and prepayment speeds. The carrying amounts of those loans included in the balance sheet amounts of loans receivable are as follows: March 31 March 31 March 31 March 31 2016 2016 2016 2016 Heartland Summit Peoples Total Commercial $ 1,282 $ 5,494 $ 962 $ 7,738 Real estate 676 1,199 289 2,164 Consumer 1 9 — 10 Outstanding balance $ 1,959 $ 6,702 $ 1,251 $ 9,912 Carrying amount, net of allowance of $0 $ 9,912 December 31 December 31 December 31 Peoples December 31 Total Commercial $ 1,633 $ 5,567 $ 1,061 $ 8,261 Real estate 693 1,216 179 2,088 Consumer 6 35 — 41 Outstanding balance $ 2,332 $ 6,818 $ 1,240 $ 10,390 Carrying amount, net of allowance of $63 $ 10,327 Accretable yield, or income expected to be collected for the three months ended March 31, is as follows: Three Months Ended March 31, 2016 Heartland Summit Peoples Total Balance at January 1 $ 795 $ 708 $ 555 $ 2,058 Additions — — — — Accretion (36 ) (55 ) (42 ) (133 ) Reclassification from nonaccretable difference — — — — Disposals (10 ) (4 ) (30 ) (44 ) Balance at March 31 $ 749 $ 649 $ 483 $ 1,881 Three Months Ended March 31, 2015 Heartland Summit Peoples Total Balance at January 1 $ 2,400 $ 1,268 $ — $ 3,668 Additions — — — — Accretion (107 ) (99 ) — (206 ) Reclassification from nonaccretable difference — — — — Disposals (88 ) (49 ) — (137 ) Balance at March 31 $ 2,205 $ 1,120 $ — $ 3,325 During the three months ended March 31, 2016 and 2015, the Company decreased the allowance for loan losses on purchased loans by a recovery to the income statement of $63,000 and $105,000, respectively.

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 the five-year historical loss experience methodology is appropriate in the current economic environment, as it captures loss rates that are comparable to the current period being analyzed. The actual allowance for loan loss activity is provided below. Three Months Ended March 31 2016 2015 (Unaudited) (Unaudited) Balance at beginning of the period $ 14,534 $ 16,501 Loans charged-off: Commercial Owner occupied real estate 147 — Non owner occupied real estate 299 16 Residential development — — Development & Spec Land Loans — — Commercial and industrial 39 — Total commercial 485 16 Real estate Residential mortgage 115 22 Residential construction — — Mortgage warehouse — — Total real estate 115 22 Consumer Direct Installment 58 59 Direct Installment Purchased — — Indirect Installment 276 369 Home Equity 175 200 Total consumer 509 628 Total loans charged-off 1,109 666 Recoveries of loans previously charged-off: Commercial Owner occupied real estate 25 8 Non owner occupied real estate 23 — Residential development 2 — Development & Spec Land Loans — — Commercial and industrial 32 19 Total commercial 82 27 Real estate Residential mortgage 32 2 Residential construction — — Mortgage warehouse — — Total real estate 32 2 Consumer Direct Installment 16 29 Direct Installment Purchased — — Indirect Installment 94 101 Home Equity 55 26 Total consumer 165 156 Total loan recoveries 279 185 Net loans charged-off (recovered) 830 481 Provision charged to operating expense Commercial (332 ) (45 ) Real estate (592 ) 933 Consumer 1,456 (274 ) Total provision charged to operating expense 532 614 Balance at the end of the period $ 14,236 $ 16,634 Certain loans are individually evaluated for impairment, and the Company’s general practice is to proactively charge down impaired loans to the fair value, which is the appraised value less estimated selling costs, of the underlying collateral. Consistent with regulatory guidance, charge-offs on all loan segments are taken when specific loans, or portions thereof, are considered uncollectible. The Company’s policy is to promptly charge these loans off in the period the uncollectible loss is reasonably determined. For all loan portfolio segments except 1-4 family residential properties and consumer, the Company promptly charges-off loans, or portions thereof, when available information confirms that specific loans are uncollectible based on information that includes, but is not limited to, (1) the deteriorating financial condition of the borrower, (2) declining collateral values, and/or (3) legal action, including bankruptcy, that impairs the borrower’s ability to adequately meet its obligations. For impaired loans that are considered to be solely collateral dependent, a partial charge-off is recorded when a loss has been confirmed by an updated appraisal or other appropriate valuation of the collateral. The Company charges-off 1-4 family residential and consumer loans, or portions thereof, when the Company reasonably determines the amount of the loss. The Company adheres to timeframes established by applicable regulatory guidance which provides for the charge-down or specific allocation of 1-4 family first and junior lien mortgages to the net realizable value less costs to sell when the value is known but no later than when a loan is 180 days past due. Pursuant to such guidelines, the Company also charges-off unsecured open-end loans when the loan is 90 days past due, and charges down to the net realizable value other secured loans when they are 90 days past due. Loans at these respective delinquency thresholds for which the Company can clearly document that the loan is both well-secured and in the process of collection, such that collection in full will occur regardless of delinquency status, are not charged off.

From time to time, the Bank obtains information that may lead management to believe that the collection of payments may be doubtful on a particular loan. In recognition of this, it is management’s policy to convert the loan from an “earning asset” to a non-accruing loan. The entire balance of a loan is considered delinquent if the minimum payment contractually required to be made is not received by the specified due date. Further, it is management’s policy to place a loan on a non-accrual status when the payment is delinquent in excess of 90 days or the loan has had the accrual of interest discontinued by management. The officer responsible for the loan and the Chief Operations Officer or the senior collection officer must review all loans placed on non-accrual status. Subsequent payments on non-accrual loans are recorded as a reduction of principal, and interest income is recorded only after principal recovery is reasonably assured. Non-accrual loans are returned to accrual status when, in the opinion of management, the financial position of the borrower indicates there is no longer any reasonable doubt as to the timely collection of interest or principal in accordance with the loan terms. The Company requires a period of satisfactory performance of not less than six months before returning a non-accrual loan to accrual status. 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 status when they are 90 days or more past due. These loans are often considered impaired. Impaired loans, or portions thereof, are charged off when deemed uncollectible. 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 estimating fair value using the fair value of the collateral for collateral-dependent loans. The Company’s TDRs are considered impaired loans and included in the allowance methodology using the guidance for impaired loans. At March 31, 2016, 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 three consecutive payments but is still reported as TDR unless the loan bears interest at a market rate.

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 credit quality. The latter usually occurs upon receipt of current financial information or other pertinent data that would trigger a change in the loan grade. • 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 $2,500,000) are validated by the Loan Committee, which is chaired by the Chief Credit Officer (CCO). • Commercial loan officers are responsible for reviewing their loan portfolios and report any adverse material change to the CCO or Loan Committee. When circumstances warrant a change in the credit quality grade, loan officers are required to notify the CCO and the Credit Department of the change in the loan grade. Downgrades are accepted immediately by the CCO, however, lenders must present their factual information to either the Loan Committee or the CCO when recommending an upgrade. • The CCO, or his designee, meets weekly with loan officers to discuss the status of past-due loans and classified loans. These meetings are also designed to give the loan officers an opportunity to identify an existing loan that should be downgraded to a classified grade. • 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, or are classified as a TDR are graded “Substandard.” After being 90 days delinquent a loan is charged off unless it is well secured and in the process of collection. If the latter case exists, the loan is placed on non-accrual. Occasionally a mortgage loan may be graded as “Special Mention.” When this situation arises, it is because the characteristics of the loan and the borrower fit the definition of a Risk Grade 5 described below, which is normally used for grading commercial loans. Loans not graded Substandard are considered Pass. 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 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 6.14% on a notional amount of $30.5 million at March 31, 2016 and December 31, 2015. 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, 2016, 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, 2016, 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 $115.1 million at March 31, 2016 and $117.3 million at December 31, 2015. Other Derivative Instruments The Company enters into non-hedging derivatives in the form of mortgage loan forward sale commitments with investors and commitments to originate mortgage loans as part of its mortgage banking business. At March 31, 2016, the Company’s fair value of these derivatives were recorded and over the next 12 months are not expected to have a significant impact on the Company’s net income. 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, 2016. 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 mortgage obligations and mortgage-backed pools, private-label 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: Fair Value Quoted Prices in Active Markets Significant Significant (Level 1) (Level 2) (Level 3) March 31, 2016 Available-for-sale securities U.S. Treasury and federal agencies $ 15,470 $ — $ 15,470 $ — State and municipal 71,042 — 71,042 — Federal agency collateralized mortgage obligations 157,313 — 157,313 — Federal agency mortgage-backed pools 218,576 — 218,576 — Corporate notes 75 — 75 — Total available-for-sale securities 462,476 — 462,476 — Hedged loans 110,837 — 110,837 — Forward sale commitments 644 — 644 — Interest rate swap agreements (7,985 ) — (7,985 ) — Commitments to originate loans — — — — December 31, 2015 Available-for-sale securities U.S. Treasury and federal agencies $ 5,926 $ — $ 5,926 $ — State and municipal 75,095 — 75,095 — Federal agency collateralized mortgage obligations 156,203 — 156,203 — Federal agency mortgage-backed pools 207,704 — 207,704 — Corporate notes 54 — 54 — Total available-for-sale securities 444,982 — 444,982 — Hedged loans 115,472 — 115,472 — Forward sale commitments 642 — 642 — Interest rate swap agreements (4,923 ) — (4,923 ) — 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 Non Interest Income 2016 2015 Total gains and losses from: (Unaudited) (Unaudited) Hedged loans $ 1,478 $ 719 Fair value interest rate swap agreements (1,478 ) (719 ) Derivative loan commitments 2 189 $ 2 $ 189 Certain other assets are measured at fair value on a nonrecurring basis in the ordinary course of business and are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment): Quoted Prices in Active Markets for Identical Assets Significant Significant Fair Value (Level 1) (Level 2) (Level 3) March 31, 2016 Impaired loans $ 4,873 $ — $ — $ 4,873 Mortgage servicing rights 9,093 — — 9,093 December 31, 2015 Impaired loans $ 6,803 $ — $ — $ 6,803 Mortgage servicing rights 8,874 — — 8,874 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. This method requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value.

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, 2016 and December 31, 2015. These include financial instruments recognized as assets and liabilities on the condensed consolidated balance sheet as well as certain off-balance sheet financial instruments. The estimated fair values shown below do not include any valuation of assets and liabilities, which are not financial instruments as defined by the FASB ASC fair value hierarchy. 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 Securities 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 items as calculated under regulatory accounting practices. The Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. 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, 2016, 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 of including accumulated other comprehensive income in regulatory capital To be categorized as well capitalized, the Bank must maintain minimum Total risk-based, Tier I risk-based, common equity Tier I risk-based (March 31, 2016) and Tier I leverage ratios as set forth in the table below. As of March 31, 2016 and December 31, 2015, 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 2016 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, 2016 and December 31, 2015 were as follows: Required For Capital 1 Well Capitalized Under Prompt 1 Actual Adequacy Purposes Corrective Action Provisions Amount Ratio Amount Ratio Amount Ratio As of March 31, 2016 Total capital 1 Consolidated $ 251,434 13.57 % $ 159,902 8.63 % N/A N/A Bank 242,478 13.10 % 159,739 8.63 % $ 185,098 10.00 % Tier 1 capital 1 Consolidated 203,797 12.80 % 105,560 6.63 % N/A N/A Bank 228,242 12.33 % 122,729 6.63 % 148,089 8.00 % Common equity tier 1 capital 1 Consolidated 203,797 11.00 % 95,044 5.13 % N/A N/A Bank 228,242 12.33 % 94,962 5.13 % 120,322 6.50 % Tier 1 capital 1 Consolidated 237,198 9.32 % 101,802 4.00 % N/A N/A Bank 228,242 8.98 % 101,667 4.00 % 127,084 5.00 % As of December 31, 2015 Total capital 1 Consolidated $ 264,452 13.99 % $ 151,223 8.00 % N/A N/A Bank 237,348 12.57 % 151,057 8.00 % $ 188,821 10.00 % Tier 1 capital 1 Consolidated 249,918 13.22 % 113,427 6.00 % N/A N/A Bank 222,814 11.80 % 113,295 6.00 % 151,060 8.00 % Common equity tier 1 capital 1 Consolidated 204,350 10.81 % 85,067 4.50 % N/A N/A Bank 222,814 11.80 % 84,971 4.50 % 122,737 6.50 % Tier 1 capital 1 Consolidated 249,918 9.82 % 101,800 4.00 % N/A N/A Bank 222,814 8.77 % 101,626 4.00 % 127,032 5.00 % 1 As defined by regulatory agencies

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.
