Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition In May 2014, the Financial Accounting Standards Board (the "FASB") issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). On January 1, 2018, the Company adopted ASU 2014-09 and all subsequent amendments to the ASU that modified Topic 606. Topic 606 creates a single framework for recognizing revenue from contracts with customers that fall within its scope and revises when it is appropriate to recognize a gain (loss) from the transfer of nonfinancial assets. Since the guidance does not apply to revenue associated with financial instruments, the new guidance did not have a material impact on revenue most closely associated with financial instruments, including interest income and expense. The majority of the Company's revenues are from financial instruments and are not within the scope of Topic 606. The Company completed its overall assessment of revenue streams and related contracts, including service charges on deposit accounts, interchange income, and trust and investment brokerage fees. Based on the assessment, the Company concluded that ASU 2014-09 did not materially change the method in which the Company currently recognizes revenue for these revenue streams. The Company also completed its evaluation of certain costs related to these revenue streams to determine whether certain revenue streams should be reported gross versus net of certain expenses. Based on its evaluation, the Company determined that the classification of certain debit card related costs should change and now be reported as expenses versus contra-revenue. This reclassification change resulted in an immaterial impact to both revenue and expense. The Company adopted ASU 2014-09 and its related amendments utilizing the modified retrospective approach. Since there was no net income impact upon adoption of this guidance, a cumulative adjustment to retained earnings was not deemed necessary. Consistent with the modified retrospective approach, the Company did not adjust prior period amounts for the debit card costs noted above. A description of the Company's revenue streams accounted for under Topic 606 follows: Service Charges on Deposit Accounts : The Company earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as stop payment charges and statement rendering, are recognized at the time the transaction is executed (the point in time the Company fills the customer's request). Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Interchange Fee Income: The Company earns interchange fees from debit/credit cardholder transactions conducted through various payment networks. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. Trust and Investment Product Fees: The Company earns trust and investment brokerage fees from its contracts with trust and brokerage customers to manage assets for investment and/or to transact their accounts. These fees are primarily earned over time as the Company provides the contracted monthly or quarterly services and are generally assessed based on the market value of assets under management at month-end. Fees that are transaction based, including trade execution services, are recognized at the point in time that the transaction is executed (trade date). Insurance Revenues : The Company earns insurance revenue from commissions derived from the sale of personal and corporate property and casualty insurance products. These commissions are primarily earned over time as the Company provides the contracted insurance product to customers. NOTE 2 - Revenue Recognition (continued) The following table presents non-interest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the three months ended March 31, 2018 and 2017.

Securities	Securities The amortized cost, unrealized gross gains and losses recognized in accumulated other comprehensive income (loss), and fair value of Securities Available-for-Sale at March 31, 2018 and December 31, 2017, were as follows: Securities Available-for-Sale: Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value March 31, 2018 Obligations of State and Political Subdivisions $ 271,135 $ 3,893 $ (2,275 ) $ 272,753 MBS/CMO - Residential 481,192 76 (16,417 ) 464,851 Total $ 752,327 $ 3,969 $ (18,692 ) $ 737,604 December 31, 2017 Obligations of State and Political Subdivisions $ 267,437 $ 6,733 $ (861 ) $ 273,309 MBS/CMO - Residential 476,205 416 (9,289 ) 467,332 Total $ 743,642 $ 7,149 $ (10,150 ) $ 740,641 All mortgage-backed securities in the above table (identified above and throughout this Note 4 as "MBS/CMO - Residential") are residential mortgage-backed securities and guaranteed by government sponsored entities. Equity securities that do not have readily determinable fair values are included as "Other Investments" on the Consolidated Balance Sheet, are carried at historical cost and are evaluated for impairment on a periodic basis. The Company's equity securities consist of one non-controlling investment in a single banking organization at March 31, 2018 and December 31, 2017. The original investment totaled $1,350 and other-than-temporary impairment was previously recorded totaling $997 . When a decline in fair value below cost is deemed to be other-than-temporary, the unrealized loss must be recognized as a charge to earnings. The amortized cost and fair value of securities at March 31, 2018 by contractual maturity are shown below. Expected maturities may differ from contractual maturities because some issuers have the right to call or prepay certain obligations with or without call or prepayment penalties. Mortgage-backed Securities are not due at a single maturity date and are shown separately in the table below.

NOTE 4 - Securities (continued) Below is a summary of securities with unrealized losses as of March 31, 2018 and December 31, 2017, presented by length of time the securities have been in a continuous unrealized loss position: Less than 12 Months 12 Months or More Total March 31, 2018 Fair Value Unrealized Loss Fair Value Unrealized Loss Fair Value Unrealized Loss Obligations of State and Political Subdivisions $ 74,634 $ (1,264 ) $ 23,716 $ (1,011 ) $ 98,350 $ (2,275 ) MBS/CMO - Residential 222,993 (5,380 ) 236,726 (11,037 ) 459,719 (16,417 ) Total $ 297,627 $ (6,644 ) $ 260,442 $ (12,048 ) $ 558,069 $ (18,692 ) Less than 12 Months 12 Months or More Total December 31, 2017 Fair Value Unrealized Loss Fair Value Unrealized Loss Fair Value Unrealized Loss Obligations of State and Political Subdivisions $ 33,230 $ (237 ) $ 24,161 $ (624 ) $ 57,391 $ (861 ) MBS/CMO - Residential 172,354 (2,048 ) 250,520 (7,241 ) 422,874 (9,289 ) Total $ 205,584 $ (2,285 ) $ 274,681 $ (7,865 ) $ 480,265 $ (10,150 ) Securities are written down to fair value when a decline in fair value is not considered temporary. In estimating other-than-temporary losses, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether the Company has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The Company does not intend to sell or expect to be required to sell these securities, and the decline in fair value is largely due to changes in market interest rates. Therefore, the Company does not consider these securities to be other-than-temporarily impaired. All mortgage-backed securities and collateralized mortgage obligations (MBS/CMO - Residential) in the Company’s portfolio are guaranteed by government sponsored entities, are investment grade, and are performing as expected.

Derivatives

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. The notional amounts of these interest rate swaps and the offsetting counterparty derivative instruments were $87.3 million at March 31, 2018 and $87.8 million at December 31, 2017. These interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions with approved, reputable, independent counterparties with substantially matching terms. The agreements are considered stand alone derivatives and changes in the fair value of derivatives are reported in earnings as non-interest income. Credit risk arises from the possible inability of counterparties to meet the terms of their contracts. The Company’s exposure is limited to the replacement value of the contracts rather than the notional, principal or contract amounts. There are provisions in the agreements with the counterparties that allow for certain unsecured credit exposure up to an agreed threshold. Exposures in excess of the agreed thresholds are collateralized. In addition, the Company minimizes credit risk through credit approvals, limits, and monitoring procedures. The following table reflects the fair value hedges included in the Consolidated Balance Sheets as of: March 31, 2018 December 31, 2017 Notional Amount Fair Value Notional Amount Fair Value Included in Other Assets: Interest Rate Swaps $ 87,257 $ 2,232 $ 87,788 $ 1,564 Included in Other Liabilities: Interest Rate Swaps $ 87,257 $ 2,210 $ 87,788 $ 1,633 The following table presents the effect of derivative instruments on the Consolidated Statements of Income for the periods presented: Three Months Ended 2018 2017 Interest Rate Swaps: Included in Other Operating Income $ 90 $ 348

General allocations of the allowance are primarily made based on historical averages for loan losses for these portfolios, judgmentally adjusted for current economic factors and portfolio trends. Loan impairment is reported when full repayment under the terms of the loan is not expected. This methodology is used for all loans, including loans acquired with deteriorated credit quality if such loans perform worse than what was expected at the time of acquisition. For purchased loans, the assessment is made at the time of acquisition as well as over the life of the loan. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported net, at the present value of estimated future cash flows using the loan’s existing rate, or at the fair value of collateral if repayment is expected solely from the collateral. Commercial and industrial loans, commercial real estate loans, and agricultural loans are evaluated individually for impairment. Smaller balance homogeneous loans are evaluated for impairment in total. Such loans include real estate loans secured by one-to-four family residences and loans to individuals for household, family and other personal expenditures. Individually evaluated loans on non-accrual are generally considered impaired. Impaired loans, or portions thereof, are charged off when deemed uncollectible. Specific allocations on impaired loans are determined by comparing the loan balance to the present value of expected cash flows or expected collateral proceeds. Allocations are also applied to categories of loans not considered individually impaired but for which the rate of loss is expected to be greater than historical averages, including non-performing consumer or residential real estate loans. Such allocations are based on past loss experience and information about specific borrower situations and estimated collateral values.

For purchased loans, the determination is made at the time of acquisition as well as over the life of the loan. Uncollected accrued interest for each class of loans is reversed against income at the time a loan is placed on non-accrual. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. All classes of loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Loans are typically charged-off at 180 days past due, or earlier if deemed uncollectible. Exceptions to the non-accrual and charge-off policies are made when the loan is well secured and in the process of collection. The following tables present the recorded investment in non-accrual loans and loans past due 90 days or more still on accrual by class of loans as of March 31, 2018 and December 31, 2017: Non-Accrual Loans Loans Past Due 90 Days or More & Still Accruing March 31, December 31, March 31, December 31, 2018 2017 2018 2017 Commercial and Industrial Loans and Leases $ 3,105 $ 4,753 $ — $ — Commercial Real Estate Loans 4,502 4,618 893 474 Agricultural Loans 697 748 228 268 Home Equity Loans 188 199 — — Consumer Loans 71 286 — — Residential Mortgage Loans 916 487 — — Total $ 9,479 $ 11,091 $ 1,121 $ 742 Loans Acquired With Deteriorated Credit Quality (Included in the Total Above) $ 822 $ 866 $ — $ — The following tables present the aging of the recorded investment in past due loans by class of loans as of March 31, 2018 and December 31, 2017: March 31, 2018 Total 30-59 Days Past Due 60-89 Days Past Due 90 Days or More Past Due Total Past Due Loans Not Past Due Commercial and Industrial Loans and Leases $ 483,512 $ 659 $ 180 $ 633 $ 1,472 $ 482,040 Commercial Real Estate Loans 950,326 1,195 — 2,237 3,432 946,894 Agricultural Loans 333,988 106 — 228 334 333,654 Home Equity Loans 152,527 529 94 188 811 151,716 Consumer Loans 64,655 303 62 71 436 64,219 Residential Mortgage Loans 178,537 3,860 123 701 4,684 173,853 Total (1) $ 2,163,545 $ 6,652 $ 459 $ 4,058 $ 11,169 $ 2,152,376 Loans Acquired With Deteriorated Credit Quality (Included in the Total Above) $ 8,819 $ 518 $ — $ 27 $ 545 $ 8,274 (1) Total recorded investment in loans includes $9,697 in accrued interest.

Troubled Debt Restructurings: In certain instances, the Company may choose to restructure the contractual terms of loans. A troubled debt restructuring occurs when the Bank grants a concession to the borrower that it would not otherwise consider due to a borrower’s financial difficulty. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without modification. This evaluation is performed under the Company’s internal underwriting policy. The Company uses the same methodology for loans acquired with deteriorated credit quality as for all other loans when determining whether the loan is a troubled debt restructuring. During the three months ended March 31, 2018, there were no loans modified as a troubled debt restructuring. During the three months ended March 31, 2017, there was one loan modified as a troubled debt restructuring. The following tables present the recorded investment of troubled debt restructurings by class of loans as of March 31, 2018 and December 31, 2017: March 31, 2018 Total Performing Non-Accrual (1) Commercial and Industrial Loans and Leases $ 224 $ 124 $ 100 Commercial Real Estate Loans — — — Total $ 224 $ 124 $ 100 December 31, 2017 Total Performing Non-Accrual (1) Commercial and Industrial Loans and Leases $ 258 $ 125 $ 133 Commercial Real Estate Loans 24 24 — Total $ 282 $ 149 $ 133 (1) The non-accrual troubled debt restructurings are included in the Non-Accrual Loan table presented on a previous page. The Company had not committed to lending any additional amounts as of March 31, 2018 and December 31, 2017 to customers with outstanding loans that are classified as troubled debt restructurings. The following tables present loans by class modified as troubled debt restructurings that occurred during the three months ending March 31, 2018 and 2017: March 31, 2018 Number of Loans Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Commercial and Industrial Loans and Leases — $ — $ — Commercial Real Estate Loans — — — Total — $ — $ — The troubled debt restructurings described above increased the allowance for loan losses by $0 and resulted in charge-offs of $0 during the three months ending March 31, 2018.

Additionally, there were no loans modified as troubled debt restructurings for which there was a payment default within twelve months following the modification during the three months ending March 31, 2018 and 2017. A loan is considered to be in payment default once it is 30 days contractually past due under the modified terms. Credit Quality Indicators: The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company classifies loans as to credit risk by individually analyzing loans. This analysis includes commercial and industrial loans, commercial real estate loans, and agricultural loans with an outstanding balance greater than $250 . This analysis is typically performed on at least an annual basis. The Company uses the following definitions for risk ratings: Special Mention. Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. Substandard. Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans. Based on the most recent analysis performed, the risk category of loans by class of loans is as follows: March 31, 2018 Pass Special Mention Substandard Doubtful Total Commercial and Industrial Loans and Leases $ 459,442 $ 7,953 $ 16,117 $ — $ 483,512 Commercial Real Estate Loans 917,878 16,163 16,285 — 950,326 Agricultural Loans 300,012 27,917 6,059 — 333,988 Total $ 1,677,332 $ 52,033 $ 38,461 $ — $ 1,767,826 Loans Acquired With Deteriorated Credit Quality (Included in the Total Above) $ 2,395 $ 1,652 $ 3,894 $ — $ 7,941 December 31, 2017 Pass Special Mention Substandard Doubtful Total Commercial and Industrial Loans and Leases $ 462,212 $ 7,901 $ 17,945 $ — $ 488,058 Commercial Real Estate Loans 894,027 18,037 16,976 — 929,040 Agricultural Loans 304,032 27,288 6,481 — 337,801 Total $ 1,660,271 $ 53,226 $ 41,402 $ — $ 1,754,899 Loans Acquired With Deteriorated Credit Quality (Included in the Total Above) $ 2,604 $ 1,647 $ 3,978 $ — $ 8,229 The Company considers the performance of the loan portfolio and its impact on the allowance for loan losses. For home equity, consumer and residential mortgage loan classes, the Company also evaluates credit quality based on the aging status of the loan, which was previously presented, and by payment activity.

Repurchase Agreements Accounted for as Secured Borrowings	Repurchase Agreements Accounted for as Secured Borrowings Repurchase agreements are short-term borrowings included in FHLB Advances and Other Borrowings and mature overnight and continuously. Repurchase agreements, which were secured by mortgage-backed securities, totaled $ 31,796 and $41,499 as of March 31, 2018 and December 31, 2017, respectively. Risk could arise when the collateral pledged to a repurchase agreement declines in fair value. The Company minimizes risk by consistently monitoring the value of the collateral pledged. At the point in time where the collateral has declined in fair value, the Company is required to provide additional collateral based on the value of the underlying securities.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company’s operations include three primary segments: core banking, trust and investment advisory services, and insurance operations. The core banking segment involves attracting deposits from the general public and using such funds to originate consumer, commercial and agricultural, commercial and agricultural real estate, and residential mortgage loans, primarily in the Company’s local markets. The core banking segment also involves the sale of residential mortgage loans in the secondary market. The trust and investment advisory services segment involves providing trust, investment advisory, and brokerage services to customers. The insurance segment offers a full range of personal and corporate property and casualty insurance products, primarily in the Company’s banking subsidiary’s local markets.

Effective April 1, 2018, the legal name of German American Bancorp was changed to German American Bank. Net interest income from loans and investments funded by deposits and borrowings is the primary revenue for the core-banking segment. The trust and investment advisory services segment’s revenues are comprised primarily of fees generated by the trust operations of the Company's banking subsidiary and by German American Investment Services, Inc. These fees are derived by providing trust, investment advisory, and brokerage services to its customers. The insurance segment primarily consists of German American Insurance, Inc., which provides a full line of personal and corporate insurance products. Commissions derived from the sale of insurance products are the primary source of revenue for the insurance segment. The following segment financial information has been derived from the internal financial statements of the Company which are used by management to monitor and manage financial performance. The accounting policies of the three segments are the same as those of the Company. The evaluation process for segments does not include holding company income and expense.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Equity Plans and Equity Based Compensation	Equity Plans and Equity Based Compensation The Company maintains three equity incentive plans under which stock options, restricted stock, and other equity incentive awards can be granted. At March 31, 2018, the Company has reserved 386,754 shares of common stock for the purpose of issuance pursuant to outstanding and future grants of options, restricted stock, and other equity awards to officers, directors and other employees of the Company. For the three months ended March 31, 2018 and 2017, the Company granted no options. The Company recorded no stock compensation expense applicable to options during the three months ended March 31, 2018 and 2017 because all outstanding options were fully vested prior to 2007. In addition, there was no unrecognized option expense. During the periods presented, awards of long-term incentives were granted in the form of restricted stock. Awards that were granted to management under a management incentive plan were granted in tandem with cash credit entitlements (typically in the form of 60% restricted stock grants and 40% cash credit entitlements). The management and employee restricted stock grants and tandem cash credit entitlements awarded will vest in three equal installments of 33.3% with the first annual vesting on December 5th of the year of the grant and on December 5th of the next two succeeding years. Awards that were granted to directors as additional retainer for their services do not include any cash credit entitlement. These director restricted stock grants are subject to forfeiture in the event that the recipient of the grant does not continue in service as a director of the Company through December 5th of the year after grant or does not satisfy certain meeting attendance requirements, at which time they generally vest 100 percent . For measuring compensation costs, restricted stock awards are valued based upon the market value of the common shares on the date of grant. During the three months ended March 31, 2018 and 2017, the Company granted awards of 34,860 and 37,890 shares of restricted stock, respectively. Total unvested restricted stock awards at March 31, 2018 and December 31, 2017 were 80,716 and 46,306 , respectively. The following table presents expense recorded for restricted stock and cash entitlements as well as the related tax information for the periods presented: Three Months Ended March 31, 2018 2017 Restricted Stock Expense $ 278 $ 306 Cash Entitlement Expense 170 158 Tax Effect (117 ) (182 ) Net of Tax $ 331 $ 282 Unrecognized expense associated with the restricted stock grants and cash entitlements totaled $3,449 and $3,201 as of March 31, 2018 and 2017, respectively. The Company maintains an Employee Stock Purchase Plan whereby eligible employees have the option to purchase the Company’s common stock at a discount. The purchase price of the shares under this Plan has been set at 95% of the fair market value of the Company’s common stock as of the last day of the plan year. The plan provided for the purchase of up to 750,000 shares of common stock, which the Company may obtain by purchases on the open market or from private sources, or by issuing authorized but unissued common shares. At March 31, 2018, there were 557,203 shares available for future issuance under this plan. Funding for the purchase of common stock is from employee and Company contributions. There was no expense recorded for the employee stock purchase plan during the three months ended March 31, 2018 and 2017. There was no unrecognized compensation expense as of March 31, 2018 and 2017 for the Employee Stock Purchase Plan.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other 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. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The Company used the following methods and significant assumptions to estimate the fair value of each type of financial instrument: Investment Securities: The fair values for investment securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3). Level 3 pricing is obtained from a third-party based upon similar trades that are not traded frequently without adjustment by the Company. At March 31, 2018, the Company held $5.5 million in Level 3 securities which consist of $5.2 million of non-rated Obligations of State and Political Subdivisions and $353 thousand of equity securities that are not actively traded. Absent the credit rating, significant assumptions must be made such that the credit risk input becomes an unobservable input and thus these securities are reported by the Company in a Level 3 classification. Derivatives: The fair values of derivatives are based on valuation models using observable market data as of the measurement date (Level 2). Impaired Loans: Fair values for impaired collateral dependent loans are generally based on appraisals obtained from licensed real estate appraisers and in certain circumstances includes consideration of offers obtained to purchase properties prior to foreclosure. Appraisals for commercial real estate generally use three methods to derive value: cost, sales or market comparison and income approach. The cost method bases value in the cost to replace the current property. Value of market comparison approach evaluates the sales price of similar properties in the same market area. The income approach considers net operating income generated by the property and an investor's required return. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Comparable sales adjustments are based on known sales prices of similar type and similar use properties and duration of time that the property has been on the market to sell. Such adjustments made in the appraisal process are typically significant and result in a Level 3 classification of the inputs for determining fair value. Appraisals for both collateral-dependent impaired loans and other real estate owned are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, a member of the Company’s Risk Management Area reviews the assumptions and approaches utilized in the appraisal. In determining the value of impaired collateral dependent loans and other real estate owned, significant unobservable inputs may be used which include: physical condition of comparable properties sold, net operating income generated by the property and investor rates of return. Other Real Estate: Nonrecurring adjustments to certain commercial and residential real estate properties classified as other real estate (ORE) are measured at the lower of carrying amount or fair value, less costs to sell. Fair values are generally based on third party appraisals of the property utilizing similar techniques as discussed above for Impaired Loans, resulting in a Level 3 classification. In cases where the carrying amount exceeds the fair value, less costs to sell, impairment loss is recognized. Loan Servicing Rights: On a quarterly basis, loan servicing rights are evaluated for impairment based upon the fair value of the rights as compared to carrying amount resulting in a Level 2 classification. The valuation model utilizes interest rate, prepayment speed, and default rate assumptions that market participants would use in estimating future net servicing income and that can be validated against available market data. Loans Held-for-Sale: The fair values of loans held for sale are determined by using quoted prices for similar assets, adjusted for specific attributes of that loan resulting in a Level 2 classification. Assets and Liabilities Measured on a Recurring Basis Assets and liabilities measured at fair value on a recurring basis, including financial assets and liabilities for which the Company has elected the fair value option, are summarized below: Fair Value Measurements at March 31, 2018 Using Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Assets: Obligations of State and Political Subdivisions $ — $ 267,582 $ 5,171 $ 272,753 MBS/CMO - Residential — 464,851 — 464,851 Equity Securities — — 353 353 Total Securities $ — $ 732,433 $ 5,524 $ 737,957 Loans Held-for-Sale $ — $ 6,628 $ — $ 6,628 Derivative Assets $ — $ 2,232 $ — $ 2,232 Mortgage Servicing Rights $ — $ 531 $ — $ 531 Derivative Liabilities $ — $ 2,210 $ — $ 2,210 Fair Value Measurements at December 31, 2017 Using Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Assets: Obligations of State and Political Subdivisions $ — $ 267,660 $ 5,649 $ 273,309 MBS/CMO - Residential — 467,332 — 467,332 Equity Securities — — 353 353 Total Securities $ — $ 734,992 $ 6,002 $ 740,994 Loans Held-for-Sale $ — $ 6,719 $ — $ 6,719 Derivative Assets $ — $ 1,564 $ — $ 1,564 Mortgage Servicing Rights $ — $ 547 $ — $ 547 Derivative Liabilities $ — $ 1,633 $ — $ 1,633 There were no transfers between Level 1 and Level 2 for the periods ended March 31, 2018 and December 31, 2017.

For the three months ended March 31, 2017, impaired loans resulted in an increase to the provision for loan losses of $278 . Impaired loans, which are measured for impairment using the fair value of the collateral for collateral dependent loans, had a carrying amount of $9,020 with a valuation allowance of $2,228 , resulting in an increase to the provision for loan losses of $1,973 for the year ended December 31, 2017. There was no Other Real Estate carried at fair value less costs to sell at March 31, 2018. No charge to earnings was included in the three months ended March 31, 2018 and 2017. There was no Other Real Estate carried at fair value less costs to sell at December 31, 2017. No charge to earnings was included in the year ended December 31, 2017. The following table presents quantitative information about Level 3 fair value measurements for financial instruments measured at fair value on a non-recurring basis at March 31, 2018 and December 31, 2017: March 31, 2018 Fair Value Valuation Technique(s) Unobservable Input(s) Range (Weighted Average) Impaired Loans - Commercial and Industrial Loans $ 2,853 Sales comparison approach Adjustment for physical condition of comparable properties sold 0%-95% (88%) Impaired Loans - Commercial Real Estate Loans $ 3,240 Sales comparison approach Adjustment for physical condition of comparable properties sold 17%-76% (47%) December 31, 2017 Fair Value Valuation Technique(s) Unobservable Input(s) Range (Weighted Average) Impaired Loans - Commercial and Industrial Loans $ 3,354 Sales comparison approach Adjustment for physical condition of comparable properties sold 0%-95% (84%) Impaired Loans - Commercial Real Estate Loans $ 3,438 Sales comparison approach Adjustment for physical condition of comparable properties sold 30%-76% (47%) The carrying amounts and estimated fair values of the Company’s financial instruments not previously presented are provided in the tables below for the periods ending March 31, 2018 and December 31, 2017. Not all of the Company’s assets and liabilities are considered financial instruments, and therefore are not included in the tables. Because no active market exists for a significant portion of the Company’s financial instruments, fair value estimates were based on subjective judgments, and therefore cannot be determined with precision. In accordance with the adoption of ASU 2016-01, the tables below present the fair values measured using an exit price notion. The fair value of loans as of December 31, 2017 was measured using an entrance price notion.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Newly Issued Accounting Pronouncements	Newly Issued Accounting Pronouncements In January 2016, the FASB amended existing guidance (ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities) that requires 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. Also, it requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. It requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables). It eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost. These amendments are effective for public business entities for fiscal years beginning after December 15, 2017, including interim periods within that reporting period. The Company notes that the impact of adoption is to carry the equity security at fair value or at cost, less impairment when fair value is not readily determinable, with observable price changes being recognized in earnings. The Company adopted ASU 2016-01 on January 1, 2018 and no adjustment to the single equity security was performed upon adoption. Also, upon adoption of ASU 2016-01, this equity security is no longer classified as available-for-sale. For additional information on this equity security, see Note 4 - Securities. Per ASU 2016-01 guidance, the Company reported the fair value of financial instruments based upon an exit price notion for March 31, 2018. For additional information, see Note 11 - Fair Value. In August 2016, the FASB issued ASU (ASU No. 2016-15, Statement of Cash Flows (Topic 320): Classification of Certain Cash Receipts and Cash Payments) to address the diversity in how certain cash receipts and cash payments are presented and classified in the statement of cash flows including the following: • Debt Prepayment or Debt Extinguishment Costs; • Settlement of Zero-Coupon Bonds or Debt with Coupon Interest Rates That Are Insignificant in Relation to the Effective Interest Rate; • Contingent Consideration payments Made Soon After a Business Combination; • Proceeds From the Settlement of Insurance Claims; • Proceeds From the Settlement of BOLI and COLI Policies; • Distributions Received From Equity Method Investees; • Beneficial Interests in Securitization Transactions; and • Application of the Predominance Principle. These amendments are effective for public business entities beginning January 1, 2018. The Company adopted ASU 2016-15 on January 1, 2018 and there was no material impact on the Company's Consolidated Statements of Cash Flows. In March 2017, the FASB amended existing guidance (ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715)) to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. The amendments require that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit costs are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. The amendments are effective for public business entities beginning January 1, 2018. The Company adopted ASU 2017-07 on January 1, 2018 and there was no material impact on the Company's Consolidated Statements of Income. In February 2016, the FASB amended existing guidance (ASU No. 2016-02, Leases (Topic 842)) that requires lessees recognize the following for all leases (with the exception of short-term leases) at the commencement date (1) A lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) A right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. These amendments are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that reporting period. Based on our leases outstanding as of March 31, 2018, the Company does not expect this new guidance to have a material impact on the consolidated results of operation. However as a result of this new guidance, the Company anticipates an estimated increase in its Consolidated Balance Sheet of approximately $6,000 . This impact will vary based on the Company's future decisions to enter into new lease agreements or exit/renew current lease agreements prior to the date of implementation. In June 2016, the FASB issued guidance (ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326)) to replace the incurred loss model with an expected loss model, which is referred to as the current expected credit loss (CECL) model. The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loan receivables, held-to-maturity debt securities, and reinsurance receivables. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor. This standard will be effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within that reporting period. The transition to the new standard will be applied as follows: • For debt securities with other-than-temporary impairment (OTTI), the guidance will be applied prospectively. • Existing purchased credit impaired (PCI) assets will be grandfathered and classified as purchased credit deteriorated (PCD) assets at the date of adoption. The asset will be grossed up for the allowance for expected credit losses for all PCD assets at the date of adoption and will continue to recognize the noncredit discount in interest income based on the yield of such assets as of the adoption date. Subsequent changes in expected credit losses will be recorded through the allowance. • For all other assets within the scope of CECL, a cumulative-effect adjustment will be recognized in retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company has formed a CECL committee that is assessing data and system needs in order to evaluate the impact of adopting the new guidance. The Company expects to recognize a one-time cumulative adjustment to the allowance for loan losses as of the beginning of the first reporting period in which the new standard is effective, but cannot estimate the amount at this time.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On February 12, 2018, German American Bancorp (now known as German American Bank) entered into a Purchase and Assumption Agreement (the “Purchase Agreement”) with MainSource Bank, a wholly-owned subsidiary of MainSource Financial Group, Inc. (“MainSource”), which provides for the acquisition by German American Bank of five MainSource Bank branch locations ( four in Columbus, Indiana, and one in Greensburg, Indiana), and certain related assets, and the assumption by German American Bank of certain related liabilities. Pursuant to the Purchase Agreement, German American Bank has agreed to assume approximately $160 million in deposits and purchase approximately $134 million in loans associated with the five bank branches. German American Bank has agreed to pay a purchase price equal to the sum of: (i) 8.0% of the balances of certain checking accounts and other demand withdrawal accounts (excluding governmental accounts with public funds); (ii) 4.5% of the balances of governmental accounts with public funds, excluding time deposits; (iii) 4.5% of the balances of money market and savings deposits, excluding governmental accounts with public funds; (iv) the net book value of all assets, including loans but excluding any accrued interest on such loans; and (v) the accrued interest with respect to purchased loans. The purchase price will be adjusted to reflect increases or decreases in the deposit balances during the six month period following the closing date. Upon written notice, German American Bank will also have the ability to put loans back to MainSource Bank during such six month period. The expected premium to be paid for deposits under the Agreement is approximately $8 million . German American Bank is also assuming the obligations of MainSource Bank related to certain leases covering the five bank branches. With the previously-announced merger of MainSource and First Financial Bancorp having been completed on April 1, 2018 and all necessary regulatory approvals having been received, the transaction is expected to close on May 18, 2018, subject to other customary closing conditions. Effective April 1, 2018, the legal name of German American Bancorp was changed to German American Bank. The new name corresponds with the trade name already being used by the banking subsidiary and promotes further distinction in nomenclature between the banking subsidiary and the bank holding company, German American Bancorp, Inc.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Basis of Presentation	The accounting and reporting policies of German American Bancorp, Inc. and its subsidiaries (hereinafter collectively referred to as the "Company") conform to U.S. generally accepted accounting principles. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted. All adjustments which are, in the opinion of management, necessary for a fair presentation of the results for the periods reported have been included in the accompanying unaudited consolidated financial statements, and all such adjustments are of a normal recurring nature.
Revenue Recognition	Revenue Recognition In May 2014, the Financial Accounting Standards Board (the "FASB") issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). On January 1, 2018, the Company adopted ASU 2014-09 and all subsequent amendments to the ASU that modified Topic 606. Topic 606 creates a single framework for recognizing revenue from contracts with customers that fall within its scope and revises when it is appropriate to recognize a gain (loss) from the transfer of nonfinancial assets. Since the guidance does not apply to revenue associated with financial instruments, the new guidance did not have a material impact on revenue most closely associated with financial instruments, including interest income and expense. The majority of the Company's revenues are from financial instruments and are not within the scope of Topic 606. The Company completed its overall assessment of revenue streams and related contracts, including service charges on deposit accounts, interchange income, and trust and investment brokerage fees. Based on the assessment, the Company concluded that ASU 2014-09 did not materially change the method in which the Company currently recognizes revenue for these revenue streams. The Company also completed its evaluation of certain costs related to these revenue streams to determine whether certain revenue streams should be reported gross versus net of certain expenses. Based on its evaluation, the Company determined that the classification of certain debit card related costs should change and now be reported as expenses versus contra-revenue. This reclassification change resulted in an immaterial impact to both revenue and expense. The Company adopted ASU 2014-09 and its related amendments utilizing the modified retrospective approach. Since there was no net income impact upon adoption of this guidance, a cumulative adjustment to retained earnings was not deemed necessary. Consistent with the modified retrospective approach, the Company did not adjust prior period amounts for the debit card costs noted above. A description of the Company's revenue streams accounted for under Topic 606 follows: Service Charges on Deposit Accounts : The Company earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as stop payment charges and statement rendering, are recognized at the time the transaction is executed (the point in time the Company fills the customer's request). Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Interchange Fee Income: The Company earns interchange fees from debit/credit cardholder transactions conducted through various payment networks. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. Trust and Investment Product Fees: The Company earns trust and investment brokerage fees from its contracts with trust and brokerage customers to manage assets for investment and/or to transact their accounts. These fees are primarily earned over time as the Company provides the contracted monthly or quarterly services and are generally assessed based on the market value of assets under management at month-end. Fees that are transaction based, including trade execution services, are recognized at the point in time that the transaction is executed (trade date). Insurance Revenues : The Company earns insurance revenue from commissions derived from the sale of personal and corporate property and casualty insurance products. These commissions are primarily earned over time as the Company provides the contracted insurance product to customers.

In February 2016, the FASB amended existing guidance (ASU No. 2016-02, Leases (Topic 842)) that requires lessees recognize the following for all leases (with the exception of short-term leases) at the commencement date (1) A lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) A right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. These amendments are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that reporting period. Based on our leases outstanding as of March 31, 2018, the Company does not expect this new guidance to have a material impact on the consolidated results of operation. However as a result of this new guidance, the Company anticipates an estimated increase in its Consolidated Balance Sheet of approximately $6,000 . This impact will vary based on the Company's future decisions to enter into new lease agreements or exit/renew current lease agreements prior to the date of implementation. In June 2016, the FASB issued guidance (ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326)) to replace the incurred loss model with an expected loss model, which is referred to as the current expected credit loss (CECL) model. The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loan receivables, held-to-maturity debt securities, and reinsurance receivables. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor. This standard will be effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within that reporting period. The transition to the new standard will be applied as follows: • For debt securities with other-than-temporary impairment (OTTI), the guidance will be applied prospectively. • Existing purchased credit impaired (PCI) assets will be grandfathered and classified as purchased credit deteriorated (PCD) assets at the date of adoption. The asset will be grossed up for the allowance for expected credit losses for all PCD assets at the date of adoption and will continue to recognize the noncredit discount in interest income based on the yield of such assets as of the adoption date. Subsequent changes in expected credit losses will be recorded through the allowance. • For all other assets within the scope of CECL, a cumulative-effect adjustment will be recognized in retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company has formed a CECL committee that is assessing data and system needs in order to evaluate the impact of adopting the new guidance. The Company expects to recognize a one-time cumulative adjustment to the allowance for loan losses as of the beginning of the first reporting period in which the new standard is effective, but cannot estimate the amount at this time.

Schedule of Carrying Amounts and Estimated Fair Values of Company's Financial Instruments	The carrying amounts and estimated fair values of the Company’s financial instruments not previously presented are provided in the tables below for the periods ending March 31, 2018 and December 31, 2017. Not all of the Company’s assets and liabilities are considered financial instruments, and therefore are not included in the tables. Because no active market exists for a significant portion of the Company’s financial instruments, fair value estimates were based on subjective judgments, and therefore cannot be determined with precision. In accordance with the adoption of ASU 2016-01, the tables below present the fair values measured using an exit price notion. The fair value of loans as of December 31, 2017 was measured using an entrance price notion.
