All mortgage-backed securities in the above table are residential mortgage-backed securities and guaranteed by government sponsored entities. The amortized cost and fair value of securities at September 30, 2017 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.

Below is a summary of securities with unrealized losses as of September 30, 2017 and December 31, 2016, presented by length of time the securities have been in a continuous unrealized loss position: Less than 12 Months 12 Months or More Total September 30, 2017 Fair Value Unrealized Loss Fair Value Unrealized Loss Fair Value Unrealized Loss Obligations of State and Political Subdivisions $ 33,584 $ (337 ) $ 6,115 $ (233 ) $ 39,699 $ (570 ) MBS/CMO - Residential 294,132 (3,665 ) 47,985 (1,258 ) 342,117 (4,923 ) Equity Securities — — — — — — Total $ 327,716 $ (4,002 ) $ 54,100 $ (1,491 ) $ 381,816 $ (5,493 ) Less than 12 Months 12 Months or More Total December 31, 2016 Fair Value Unrealized Loss Fair Value Unrealized Loss Fair Value Unrealized Loss Obligations of State and Political Subdivisions $ 108,918 $ (3,678 ) $ — $ — $ 108,918 $ (3,678 ) MBS/CMO - Residential 356,040 (8,782 ) 47,271 (1,636 ) 403,311 (10,418 ) Equity Securities — — — — — — Total $ 464,958 $ (12,460 ) $ 47,271 $ (1,636 ) $ 512,229 $ (14,096 ) 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. The Company's equity securities consist of one non-controlling investment in a single banking organization at September 30, 2017 and December 31, 2016. 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.

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 $88.3 million at September 30, 2017 and $67.9 million at December 31, 2016. 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: September 30, 2017 December 31, 2016 Notional Amount Fair Value Notional Amount Fair Value Included in Other Assets: Interest Rate Swaps $ 88,303 $ 1,750 $ 67,902 $ 1,291 Included in Other Liabilities: Interest Rate Swaps $ 88,303 $ 1,848 $ 67,902 $ 1,238 The following table presents the effect of derivative instruments on the Consolidated Statements of Income for the periods presented: Three Months Ended Nine Months Ended 2017 2016 2017 2016 Interest Rate Swaps: Included in Other Operating Income $ 101 $ 670 $ 449 $ 828

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 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.

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 September 30, 2017 there were no loan modified as a troubled debt restructuring. During the nine months ended September 30, 2017, there were two loans modified as troubled debt restructurings. During the three and nine months ended September 30, 2016, there were no loans modified as troubled debt restructurings. The following tables present the recorded investment of troubled debt restructurings by class of loans as of September 30, 2017 and December 31, 2016: September 30, 2017 Total Performing Non-Accrual (1) Commercial and Industrial Loans and Leases $ 152 $ 152 $ — Commercial Real Estate Loans — — — Total $ 152 $ 152 $ — December 31, 2016 Total Performing Non-Accrual (1) Commercial and Industrial Loans and Leases $ 28 $ 28 $ — Commercial Real Estate Loans — — — Total $ 28 $ 28 $ — (1) The non-accrual troubled debt restructurings are included in the Non-Accrual Loan table presented on a previous page.

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 and nine months ending September 30, 2017 and 2016. 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: September 30, 2017 Pass Special Mention Substandard Doubtful Total Commercial and Industrial Loans and Leases $ 450,359 $ 9,374 $ 16,434 $ — $ 476,167 Commercial Real Estate Loans 862,066 21,642 17,229 — 900,937 Agricultural Loans 299,002 25,725 6,755 — 331,482 Total $ 1,611,427 $ 56,741 $ 40,418 $ — $ 1,708,586 Loans Acquired With Deteriorated Credit Quality (Included in the Total Above) $ 1,172 $ 3,060 $ 3,973 $ — $ 8,205 December 31, 2016 Pass Special Mention Substandard Doubtful Total Commercial and Industrial Loans and Leases $ 437,353 $ 10,454 $ 10,731 $ — $ 458,538 Commercial Real Estate Loans 814,033 26,549 17,448 — 858,030 Agricultural Loans 287,975 14,670 4,301 — 306,946 Total $ 1,539,361 $ 51,673 $ 32,480 $ — $ 1,623,514 Loans Acquired With Deteriorated Credit Quality (Included in the Total Above) $ 1,897 $ 3,121 $ 5,032 $ — $ 10,050 Loans Acquired in Current Year (Included in the Total Above) $ 175,915 $ 11,638 $ 8,145 $ — $ 195,698 The Company considers the performance of the loan portfolio and its impact on the allowance for loan losses.

Transfers and Servicing [Abstract]
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 $ 40,899 and $42,412 as of September 30, 2017 and December 31, 2016, 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. The core banking segment is comprised by the Company’s banking subsidiary, German American Bancorp, which operated through 53 banking offices at September 30, 2017. 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. Holding company amounts are the primary differences between segment amounts and consolidated totals, and are reflected in the column labeled “Other” below, along with amounts to eliminate transactions between segments.

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 September 30, 2017, the Company has reserved 412,104 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 and nine months ended September 30, 2017 and 2016, the Company granted no options. The Company recorded no stock compensation expense applicable to options during the three and nine months ended September 30, 2017 and 2016 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 September 30, 2017 and 2016, the Company granted awards of 390 and 270 shares of restricted stock, respectively. During the nine months ended September 30, 2017 and 2016, the Company granted awards of 38,490 and 48,645 shares of restricted stock, respectively. Total unvested restricted stock awards at September 30, 2017 and December 31, 2016 were 91,653 and 53,163 , 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 September 30, 2017 2016 Restricted Stock Expense $ 303 $ 267 Cash Entitlement Expense 155 143 Tax Effect (180 ) (166 ) Net of Tax $ 278 $ 244 Nine Months Ended 2017 2016 Restricted Stock Expense $ 952 $ 1,122 Cash Entitlement Expense 495 427 Tax Effect (568 ) (627 ) Net of Tax $ 879 $ 922 Unrecognized expense associated with the restricted stock grants and cash entitlements totaled $2,277 and $2,011 as of September 30, 2017 and 2016, 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 September 30, 2017, there were 577,426 shares available for future issuance under this plan. Funding for the purchase of common stock is from employee and Company contributions. There was $32 expense recorded for the employee stock purchase plan during the three and nine months ended September 30, 2017. There was $82 expense recorded for the employee stock purchase plan during the three and nine months ended September 30, 2016. There was no unrecognized compensation expense as of September 30, 2017 and 2016 for the Employee Stock Purchase Plan.

Fair Value

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 September 30, 2017, the Company held $6.1 million in Level 3 securities which consist of $5.7 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 September 30, 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 $ — $ 260,754 $ 5,742 $ 266,496 MBS/CMO - Residential — 474,861 — 474,861 Equity Securities — — 353 353 Total Securities $ — $ 735,615 $ 6,095 $ 741,710 Loans Held-for-Sale $ — $ 8,484 $ — $ 8,484 Derivative Assets $ — $ 1,750 $ — $ 1,750 Mortgage Servicing Rights $ — $ 563 $ — $ 563 Derivative Liabilities $ — $ 1,848 $ — $ 1,848 Fair Value Measurements at December 31, 2016 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 $ — $ 240,495 $ 7,024 $ 247,519 MBS/CMO - Residential — 461,914 — 461,914 Equity Securities — — 353 353 Total Securities $ — $ 702,409 $ 7,377 $ 709,786 Loans Held-for-Sale $ — $ 15,273 $ — $ 15,273 Derivative Assets $ — $ 1,291 $ — $ 1,291 Mortgage Servicing Rights $ — $ 611 $ — $ 611 Derivative Liabilities $ — $ 1,238 $ — $ 1,238 There were no transfers between Level 1 and Level 2 for the periods ended September 30, 2017 and December 31, 2016.

FHLB Stock and Other Restricted Stock: It is not practical to determine the fair values of FHLB stock and other restricted stock due to restrictions placed on their transferability. Loans: Fair values of loans, excluding loans held for sale and collateral dependent impaired loans carried at fair value, are estimated as follows: For variable rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values resulting in a Level 3 classification. Fair values for other loans are estimated using discounted cash flow analysis, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality resulting in a Level 3 classification. Impaired loans are valued as described previously. The methods utilized to estimate fair value of loans do not necessarily represent an exit price. Accrued Interest Receivable: The carrying amount of accrued interest approximates fair value resulting in a Level 2 or Level 3 classification consistent with the asset they are associated with. Deposits: The fair values disclosed for demand deposits (e.g., interest and non-interest checking, savings and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amount) resulting in a Level 1 classification. Fair values for fixed rate time deposits are estimated using a discounted cash flows calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits resulting in a Level 2 classification. Short-term Borrowings: The carrying amounts of federal funds purchased, borrowings under repurchase agreements, and other short-term borrowings, generally maturing within ninety days, approximate their fair values resulting in a Level 2 classification. Long-term Debt: The fair values of the Company’s long-term borrowings are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 2 classification. The fair values of the Company’s subordinated debentures are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 3 classification. Accrued Interest Payable: The carrying amount of accrued interest approximates fair value resulting in a Level 2 or Level 3 classification consistent with the liability they are associated with.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Newly Issued Accounting Pronouncements	Newly Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (the "FASB") amended existing guidance (ASU 2014-09 Revenue From Contracts With Customers) related to revenue from contracts with customers. This amendment supersedes and replaces nearly all existing revenue recognition guidance, including industry-specific guidance, establishes a new control-based revenue recognition model, changes the basis for deciding when revenue is recognized over time or at a point in time, provides new and more detailed guidance on specific topics and expands and improves disclosures about revenue. In addition, this amendment specifies the accounting for some costs to obtain or fulfill a contract with a customer. These amendments are effective for public business entities for fiscal periods beginning after December 15, 2017, including interim periods within that reporting period. The Company does not expect this pronouncement to have a material impact on the Company's consolidated results of operations and financial condition as the Company's core revenue does not fall under this guidance. Even though the Company does not expect this pronouncement to have a material impact on the Company's consolidated results, the Company will have additional disclosures beginning in the first quarter of 2018 as required by this guidance. 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 through the income statement or at cost, less impairment when fair value is not readily determinable, with observable price changes being recognized in earnings. The Company doesn't expect the impact to be material. For additional information on this equity security, see Note 4 - Securities. 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 September 30, 2017, 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. These amendments are effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within that reporting period. The Company anticipates there may be an increase in its allowance for loan losses at the time of adoption of this standard, but can not estimate the amount at this time. In August 2016, the FASB issued this 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 for fiscal years beginning after December 15, 2017, including interim periods within that reporting period. This guidance currently has no material impact on the Company's Consolidated Statements of Cash Flows; however, the Company will continue to monitor it going forward. In March 2017, the FASB issued this ASU (ASU No. 2017-08, Premium Amortization on Purchased Callable Debt Securities) to align the accounting with the economics of a callable debt security and to align the amortization period with expectations that already are included in market pricing on the callable debt securities. This ASU will shorten the amortization period for premiums on purchased callable debt securities by requiring that premiums be amortized to the first (or earliest) call date instead of as an adjustment to the yield over the contractual life. This guidance is effective for for public business entities for fiscal years beginning after December 15, 2018, including interim period within that reporting period. As a result of the Company's analysis, the Company doesn't expect this pronouncement to have a material impact on its consolidated results of operations and financial condition.
