Accounting Policies [Abstract]
OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Principles of Consolidation
	The accompanying consolidated financial statements include the accounts of Penns Woods Bancorp, Inc. and its wholly owned subsidiaries, Jersey Shore State Bank (“JSSB”), Luzerne Bank ("Luzerne" collectively with JSSB "Banks"), Woods Real Estate Development Co., Inc., Woods Investment Company, Inc., and The M Group Inc. D/B/A The Comprehensive Financial Group (“The M Group”), a wholly owned subsidiary of the Bank (collectively, the “Company”).  All significant intercompany balances and transactions have been eliminated.
	Nature of Business
	The Banks engage in a full-service commercial banking business, making available to the community a wide range of financial services including, but not limited to, installment loans, credit cards, mortgage and home equity loans, lines of credit, construction financing, farm loans, community development loans, loans to non-profit entities and local government, and various types of demand and time deposits including, but not limited to, checking accounts, savings accounts, money market deposit accounts, certificates of deposit, and IRAs.  Deposits are insured by the Federal Deposit Insurance Corporation (“FDIC”) to the extent provided by law.
	The financial services are provided by the Banks to individuals, partnerships, non-profit organizations, and corporations through their twenty-two offices located in Clinton, Lycoming, Centre, Montour, and Luzerne Counties, Pennsylvania.
	Woods Real Estate Development Co., Inc. engages in real estate transactions on behalf of Penns Woods Bancorp, Inc. and the Banks.
	Woods Investment Company, Inc., a Delaware holding company, is engaged in investing activities.
	The M Group engages in securities brokerage and financial planning services, which include the sale of life insurance products, annuities, and estate planning services.
	Operations are managed and financial performance is evaluated on a corporate-wide basis.  Accordingly, all financial service operations are considered by management to be aggregated in one reportable operating segment.
	Use of Estimates
	The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results may differ from those estimates.
	Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, valuation of net deferred tax assets, impairment of goodwill, other than temporary impairment of debt and equity securities, fair value of financial instruments, and the valuation of real estate acquired through, or in lieu of, foreclosure on settlement of debt.
	Cash and Cash Equivalents
	Cash and cash equivalents include cash on hand and in banks and federal funds sold.  Interest-earning deposits mature within 90 days and are carried at cost.  Net cash flows are reported for loan, deposit, and short-term borrowing transactions.
	Restrictions on Cash and Cash Equivalents
	Based on deposit levels, the Banks must maintain cash and other reserves with the Federal Reserve Bank of Philadelphia (FRB).
	Investment Securities
	Investment securities are classified at the time of purchase, based on management’s intention and ability, as securities held to maturity or securities available for sale.  Debt securities acquired with the intent and ability to hold to maturity are stated at cost, adjusted for amortization of premium and accretion of discount, which are computed using the interest method and recognized as adjustments of interest income. Certain other debt securities have been classified as available for sale to serve principally as a source of liquidity.  Unrealized holding gains and losses for available for sale securities are reported as a separate component of shareholders’ equity, net of tax, until realized.  Realized security gains and losses are computed using the specific identification method for debt securities and the average cost method for marketable equity securities.  Interest and dividends on investment securities are recognized as income when earned.
	Securities are periodically reviewed for other-than-temporary impairment based upon a number of factors, including, but not limited to, the length of time and extent to which the fair value has been less than cost, the financial condition of the underlying issuer, the ability of the issuer to meet contractual obligations, the likelihood of the security’s ability to recover any decline in its fair value, whether it is more likely than not that the Company would be required to sell the security before its anticipated recovery in fair value, and a review of the Company’s capital adequacy, interest rate risk position, and liquidity. The assessment of a security’s ability to recover any decline in fair value, the ability of the issuer to meet contractual obligations, and management’s intent and ability requires considerable judgment. A decline in value that is considered to be other-than-temporary is recorded as a loss within non-interest income in the Consolidated Statement of Income.
	Investment securities fair values are based on observed market prices.  Certain investment securities do not have observed bid prices and their fair value is based on instruments with similar risk elements. Since regulatory stock is redeemable at par, the Company carries it at cost.
	Loans
	Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff generally are stated at the principal amount outstanding, net of deferred fees and discounts, unamortized loan fees and costs, and the allowance for loan losses. Interest on loans is recognized as income when earned on the accrual method.  The Company’s general policy has been to stop accruing interest on loans when it is determined a reasonable doubt exists as to the collectability of additional interest. Income is subsequently recognized only to the extent that cash payments are received provided the loan is not delinquent in payment and, in management’s judgment, the borrower has the ability and intent to make future principal payments.  Otherwise, payments are applied to the unpaid principal balance of the loan.  Loans are restored to accrual status if certain conditions are met, including but not limited to, the repayment of all unpaid interest and scheduled principal due, ongoing performance consistent with the contractual agreement, and the future expectation of continued, timely payments.
	Loan origination and commitment fees as well as certain direct loan origination costs are being deferred and amortized as an adjustment to the related loan’s yield over the contractual lives of the related loans.
	Allowance for Loan Losses
	The allowance for loan losses represents the amount which management estimates is adequate to provide for probable losses inherent in its loan portfolio, as of the Consolidated Balance Sheet date.  The allowance method is used in providing for loan losses.  Accordingly, all loan losses are charged to the allowance and all recoveries are credited to it.  The allowance for loan losses is established through a provision for loan losses charged to operations.  The provision for loan losses is based upon management’s quarterly review of the loan portfolio.  The purpose of the review is to assess loan quality, identify impaired loans, analyze delinquencies, ascertain loan growth, evaluate potential charge-offs and recoveries, and assess general economic conditions in the markets served.  An external independent loan review is also performed annually for the Bank.  Management remains committed to an aggressive program of problem loan identification and resolution.
	The allowance is calculated by applying loss factors to outstanding loans by type, excluding loans for which a specific allowance has been determined.  Loss factors are based on management’s consideration of the nature of the portfolio segments, changes in mix and volume of the loan portfolio, historical loan loss experience, and general economic conditions.  In addition, management considers industry standards and trends with respect to nonperforming loans and its knowledge and experience with specific lending segments.
	Although management believes that it uses the best information available to make such determinations and that the allowance for loan losses is adequate at December 31, 2014, future adjustments could be necessary if circumstances or economic conditions differ substantially from the assumptions used in making the initial determinations.  A downturn in the local economy, rising unemployment, or negative performance trends in financial information from borrowers could be indicators of subsequent increased levels of nonperforming assets and possible charge-offs, which would normally require increased loan loss provisions. An integral part of the periodic regulatory examination process is the review of the adequacy of the Banks' loan loss allowance. The regulatory agencies could require the Banks, based on their evaluation of information available at the time of their examination, to provide additional loan loss provisions to further supplement the allowance.
	Impaired loans are commercial and commercial real estate loans for which it is probable the Banks will not be able to collect all amounts due according to the contractual terms of the loan agreement.  The Banks individually evaluate such loans for impairment and do not aggregate loans by major risk classifications.  The definition of “impaired loans” is not the same as the definition of “nonaccrual loans,” although the two categories overlap.  The Banks may choose to place a loan on nonaccrual status due to payment delinquency or uncertain collectability, while not classifying the loan as impaired if the loan is not a commercial or commercial real estate loan. Factors considered by management in determining impairment include payment status and collateral value.  The amount of impairment for these types of loans is determined by the difference between the present value of the expected cash flows related to the loan, using the original interest rate, and its recorded value, or as a practical expedient in the case of collateralized loans, the difference between the fair value of the collateral and the recorded amount of the loans.  When foreclosure is probable, impairment is measured based on the fair value of the collateral.
	Mortgage loans on one-to-four family properties and all consumer loans are large groups of smaller-balance homogeneous loans and are measured for impairment collectively.  Loans that experience insignificant payment delays, which are defined as 90 days or less, generally are not classified as impaired.  Management determines the significance of payment delays on a case-by-case basis taking into consideration all circumstances surrounding the loan and the borrower including the length of the delay, the borrower’s prior payment record, and the amount of shortfall in relation to the principal and interest owed.
	Loan Charge-off Policies
	Loans are generally fully or partially charged down to the fair value of collateral securing the asset when:
	•	management judges the asset to be uncollectible;
	•	repayment is deemed to be protracted beyond reasonable time frames;
	•	the asset has been classified as a loss by either the internal loan review process or external examiners;
	•	the borrower has filed bankruptcy and the loss becomes evident due to a lack of assets; or
	•	the loan is 180 days past due unless both well secured and in the process of collection.
	Troubled Debt Restructurings
	In situations where, for economic or legal reasons related to a borrower’s financial difficulties, management may grant a concession for other than an insignificant period of time to the borrower that would not otherwise be considered, the related loan is classified as a troubled debt restructuring (TDR). Management strives to identify borrowers in financial difficulty early and work with them to modify to more affordable terms before their loan reaches nonaccrual status. These modified terms may include rate reductions, principal forgiveness, payment forbearance, and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral. In cases where borrowers are granted new terms that provide for a reduction of either interest or principal, management measures any impairment on the restructuring as noted above for impaired loans.
	In addition to the allowance for the pooled portfolios, management has developed a separate allowance for loans that are identified as impaired through a TDR. These loans are excluded from pooled loss forecasts and a separate reserve is provided under the accounting guidance for loan impairment. Consumer loans whose terms have been modified in a TDR are also individually analyzed for estimated impairment.
	Loans Held for Sale
	In general, fixed rate residential mortgage loans originated by the Banks are held for sale and are carried at cost due to their short holding period, which can range from less than two weeks to a maximum of thirty days.  Sold loans are not serviced by the Banks. Proceeds from the sale of loans in excess of the carrying value are accounted for as a gain.  Total gains on the sale of loans are shown as a component of non-interest income within the Consolidated Statement of Income.
	Foreclosed Assets
	Foreclosed assets are carried at the lower of cost or fair value less estimated selling costs.  Prior to foreclosure, the value of the underlying loan is written down to the fair value of the real estate to be acquired by a charge to the allowance for loan losses, if necessary. Any subsequent write-downs are charged against operating expenses.  Net operating expenses and gains and losses realized from disposition are included in non-interest expense and income, respectively, within the Consolidated Statement of Income.
	Premises and Equipment
	Land is carried at cost.  Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed using straight-line and accelerated methods over the estimated useful lives of the related assets, which range from five to ten years for furniture, fixtures, and equipment and fifteen to forty years for buildings and improvements.  Costs incurred for routine maintenance and repairs are charged to operations as incurred.  Costs of major additions and improvements are capitalized.
	Bank-Owned Life Insurance
	The Company has purchased life insurance policies on certain officers and directors.  Bank-owned life insurance is recorded at its cash surrender value, or the amount that can be realized.  Increases in the cash surrender value are recognized as a component of non-interest income within the Consolidated Statement of Income.
	Goodwill
	The Company performs an annual impairment analysis of goodwill for its purchased subsidiaries, Luzerne and The M Group.  Based on the fair value of these reporting units, estimated using the expected present value of future cash flows, no impairment of goodwill was recognized in 2014, 2013, or 2012.
	Intangible Assets
	At December 31, 2014, the Company had intangible assets of $1,456,000 as a result of the acquisition of Luzerne National Bank Corporation, which is net of accumulated amortization of $558,000. These intangible assets will continue to be amortized using the sum-of-the-years digits method of amortization over ten years.
	Investments in Limited Partnerships
	The Company is a limited partner in four partnerships at December 31, 2014 that provide low income elderly housing in the Company’s geographic market area. The carrying value of the Company’s investments in limited partnerships was $1,560,000 at December 31, 2014 and $2,221,000 at December 31, 2013. One investment is fully amortized, while the other three are being amortized over the ten-year tax credit receipt period utilizing the straight-line method.  The partnerships are amortized once the projects reach the level of occupancy needed to begin the ten year tax credit recognition period.  Amortization of limited partnership investments amounted to $661,000 in 2014, 2013, and 2012.
	Off-Balance Sheet Financial Instruments
	In the ordinary course of business, the Company enters into off-balance sheet financial instruments. Those instruments consist of commitments to extend credit and standby letters of credit. When those instruments are funded or become payable, the Company reports the amounts in its financial statements.
	Advertising Cost
	Advertising costs are generally expensed as incurred.
	Income Taxes
	The Company prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met.
	Deferred tax assets and liabilities result from temporary differences in financial and income tax methods of accounting, and are reflected at currently enacted income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes.  The Company analyzed its deferred tax asset position and determined that there was not a need for a valuation allowance due to the Company’s ability to generate future ordinary and capital taxable income.
	The Company when applicable recognizes interest and penalties on income taxes as a component of income tax provision.
	Earnings Per Share
	The Company provides dual presentation of basic and diluted earnings per share.  Basic earnings per share is calculated utilizing net income as reported in the numerator and weighted average shares outstanding in the denominator.  The computation of diluted earnings per share differs in that the dilutive effects of any stock options are adjusted in the denominator.
Employee Benefits
Pension and employee benefits include contributions, determined actuarially, to a defined benefit retirement plan covering the eligible employees of JSSB.  The plan is funded on a current basis to the extent that it is deductible under existing federal tax regulations.  Pension and other employee benefits also include contributions to a defined contribution Section 401(k) plan covering eligible employees.  Contributions matching those made by eligible employees are funded throughout the year. In addition, an elective contribution is made annually at the discretion of the board of directors for the employees of JSSB.
The M Group Products and Income Recognition
The M Group product line is comprised primarily of annuities, life insurance, and mutual funds.  The revenues generated from life insurance sales are commission only, as The M Group does not underwrite the policies.  Life insurance sales include permanent and term policies with the majority of the policies written being permanent.  Term life insurance policies are written for 10, 15, 20, and 30 year terms with the majority of the policies being written for 20 years.  None of these products are offered as an integral part of lending activities.
Commissions from the sale of annuities are recognized at the time notice is received from the third party broker/dealer or an insurance company that the transaction has been accepted and approved, which is also the time when commission income is received.
Life insurance commissions are recognized at varying points based on the payment option chosen by the customer.  Commissions from monthly and annual payment plans are recognized at the start of each annual period for the life insurance, while quarterly and semi-annual premium payments are recognized quarterly and semi-annually when the earnings process is complete.  For example, semi-annual payments on the first of January and July would result in commission income recognition on the first of January and July, while payments on the first of January, April, July, and October would result in commission income recognition on those dates. The potential for chargebacks only exists for those policies on a monthly payment plan since income is recognized at the beginning of the annual coverage period versus at the time of each monthly payment.  No liability is maintained for chargebacks as these are removed from income at the time of the occurrence.
Accumulated Other Comprehensive Income (Loss)
The Company is required to present accumulated other comprehensive income (loss) in a full set of general-purpose financial statements for all periods presented. Accumulated other comprehensive income (loss) is comprised of unrealized holding gains (losses) on the available for sale securities portfolio and the unrecognized components of net periodic benefit costs of the defined benefit pension plan.
Segment Reporting
The Company has determined that its only reportable segment is Community Banking.
Reclassification of Comparative Amounts
Certain items previously reported have been reclassified to conform to the current year’s reporting format.  Such reclassifications did not affect net income or shareholders’ equity.
Recent Accounting Pronouncements
In January 2014, FASB issued ASU 2014-01, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects. The amendments in this update permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The amendments in this update should be applied retrospectively to all periods presented. A reporting entity that uses the effective yield method to account for its investments in qualified affordable housing projects before the date of adoption may continue to apply the effective yield method for those preexisting investments. The amendments in this update are effective for public business entities for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted. This ASU did not have an impact on the Company’s financial statements.
In January 2014, the FASB issued ASU 2014-04, Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The amendments in this update clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor, and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The amendments in this update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. An entity can elect to adopt the amendments in this update using either a modified retrospective transition method or a prospective transition method. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.
In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (a new revenue recognition standard). The update’s core principle is that a company will recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, this update specifies the accounting for certain costs to obtain or fulfill a contract with a customer and expands disclosure requirements for revenue recognition. This update is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.
In June 2014, the FASB issued ASU 2014-11, Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. The amendments in this update change the accounting for repurchase-to-maturity transactions to secured borrowing accounting. For repurchase financing arrangements, the amendments require separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. The amendments also require enhanced disclosures. The accounting changes in this update are effective for the first interim or annual period beginning after December 15, 2014. An entity is required to present changes in accounting for transactions outstanding on the effective date as a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. Earlier application is prohibited. The disclosure for certain transactions accounted for as a sale is required to be presented for interim and annual periods beginning after December 15, 2014, and the disclosure for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions accounted for as secured borrowings is required to be presented for annual periods beginning after December 15, 2014, and for interim periods beginning after March 15, 2015. The disclosures are not required to be presented for comparative periods before the effective date. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.
In June 2014, the FASB issued ASU 2014-12, Compensation-Stock Compensation (Topic 718): Accounting for Share-Based Payments when the Terms of an Award Provide that a Performance Target Could Be Achieved After the Requisite Service Period. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The amendments in this update are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Earlier adoption is permitted. Entities may apply the amendments in this update either (a) prospectively to all awards granted or modified after the effective date or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. If retrospective transition is adopted, the cumulative effect of applying this update as of the beginning of the earliest annual period presented in the financial statements should be recognized as an adjustment to the opening retained earnings balance at that date. Additionally, if retrospective transition is adopted, an entity may use hindsight in measuring and recognizing the compensation cost. This ASU did not have a significant impact on the Company’s financial statements.
In August 2014, the FASB issued ASU 2014-14, Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40). The amendments in this update require that a mortgage loan be de-recognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: (1) the loan has a government guarantee that is not separable from the loan before foreclosure, (2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim, and (3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The amendments in this update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. This ASU did not have a significant impact on the Company’s financial statements.
In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40). The amendments in this update provide guidance in accounting principles generally accepted in the United States of America about management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. The amendments in this update are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. This ASU is not expected to have a significant impact on the Company’s financial statements.
In November 2014, the FASB issued ASU 2014-17, Business Combinations (Topic 805): Pushdown Accounting. The amendments in this update apply to the separate financial statements of an acquired entity and its subsidiaries that are a business or nonprofit activity (either public or nonpublic) upon the occurrence of an event in which an acquirer (an individual or an entity) obtains control of the acquired entity. An acquired entity may elect the option to apply pushdown accounting in the reporting period in which the change-in-control event occurs. If pushdown accounting is not applied in the reporting period in which the change-in-control event occurs, an acquired entity will have the option to elect to apply pushdown accounting in a subsequent reporting period to the acquired entity's most recent change-in-control event. The amendments in this update are effective on November 18, 2014. After the effective date, an acquired entity can make an election to apply the guidance to future change-in-control events or to its most recent change-in-control event. This update will not have an impact on the Company’s financial statements.
In January 2015, the FASB issued ASU 2015-01, Income Statement -Extraordinary and Unusual Items, as part of its initiative to reduce complexity in accounting standards. This update eliminates from GAAP the concept of extraordinary items. The amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. A reporting entity may apply the amendments prospectively. A reporting entity also may apply the amendments retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. This update is not expected to have a significant impact on the Company’s financial statements.

	At December 31, 2014 there were 45 individual securities in a continuous unrealized loss position for less than twelve months and 31 individual securities in a continuous unrealized loss position for greater than twelve months.
	The Company reviews its position quarterly and has asserted that at December 31, 2014 and 2013, the declines outlined in the above table represent temporary declines and the Company does not intend to sell and does not believe they will be required to sell these securities before recovery of their cost basis, which may be at maturity.  The Company has concluded that any impairment of its investment securities portfolio is not other than temporary but is the result of interest rate changes that are not expected to result in the non-collection of principal and interest during the period.
	The amortized cost and fair value of debt securities at December 31, 2014, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities since borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

FEDERAL HOME LOAN BANK STOCK	FEDERAL HOME LOAN BANK STOCK
	The Banks are members of the Federal Home Loan Bank (“FHLB”) of Pittsburgh and as such, is required to maintain a minimum investment in stock of the FHLB that varies with the level of advances outstanding with the FHLB.  The stock is bought from and sold to the FHLB based upon its $100 par value.  The stock does not have a readily determinable fair value and as such is classified as restricted stock, carried at cost and evaluated for impairment as necessary.  The stock’s value is determined by the ultimate recoverability of the par value rather than by recognizing temporary declines. The determination of whether the par value will ultimately be recovered is influenced by criteria such as the following: (a) the significance of the decline in net assets of the FHLB as compared to the capital stock amount and the length of time this situation has persisted (b) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance (c) the impact of legislative and regulatory changes on the customer base of the FHLB and (d) the liquidity position of the FHLB.
	Management evaluated the stock and concluded that the stock was not impaired for the periods presented herein.  Management considered that the FHLB maintains regulatory capital ratios in excess of all regulatory capital requirements, liquidity appears adequate, new shares of FHLB stock continue to change hands at the $100 par value, and the payment of dividends.

	Purchased loans acquired are recorded at fair value on their purchase date without a carryover of the related allowance for loan losses.
	Upon acquisition, the Company evaluated whether each acquired loan (regardless of size) was within the scope of ASC 310-30.  Purchased credit-impaired loans are loans that have evidence of credit deterioration since origination and it is probable at the date of acquisition that the Company will not collect all contractually required principal and interest payments. The fair value of purchased credit-impaired loans, on the acquisition date, was determined, primarily based on the fair value of loan collateral.  The carrying value of purchased loans acquired with deteriorated credit quality was $349,000 at December 31, 2014. The remaining carrying value of the purchased loan acquired with deteriorated credit quality was transfered into other real estate owned by the Bank during the 3rd and 4th quarters of 2014.
	On the acquisition date, the preliminary estimate of the unpaid principal balance for all loans evidencing credit impairment acquired in the Luzerne acquisition was $1,211,000 and the estimated fair value of the loans was $878,000. Total contractually required payments on these loans, including interest, at the acquisition date was $1,783,000. However, the Company’s preliminary estimate of expected cash flows was $941,000. At such date, the Company established a credit risk related non-accretable discount (a discount representing amounts which are not expected to be collected from the customer nor liquidation of collateral) of $842,000 relating to these impaired loans, reflected in the recorded net fair value. Such amount is reflected as a non-accretable fair value adjustment to loans. The Company further estimated the timing and amount of expected cash flows in excess of the estimated fair value and established an accretable discount of $63,000 on the acquisition date relating to these impaired loans.
	The carrying value of the loans acquired and accounted for in accordance with ASC 310-30, was determined by projecting discounted contractual cash flows. The table below presents the components of the purchase accounting adjustments related to the purchased impaired loans acquired in the Luzerne acquisition as of June 1, 2013:

Impaired Loans
Impaired loans are loans for which it is probable the Banks will not be able to collect all amounts due according to the contractual terms of the loan agreement.  The Banks individually evaluate such loans for impairment and do not aggregate loans by major risk classifications.  The definition of “impaired loans” is not the same as the definition of “non-accrual loans,” although the two categories overlap.  The Banks may choose to place a loan on non-accrual status due to payment delinquency or uncertain collectability, while not classifying the loan as impaired. Factors considered by management in determining impairment include payment status and collateral value.  The amount of impairment for these types of loans is determined by the difference between the present value of the expected cash flows related to the loan, using the original interest rate, and its recorded value, or as a practical expedient in the case of collateralized loans, the difference between the fair value of the collateral and the recorded amount of the loan.  When foreclosure is probable, impairment is measured based on the fair value of the collateral.
Management evaluates individual loans in all of the commercial segments for possible impairment if the loan is greater than $100,000 and if the loan is either on non-accrual status or has a risk rating of substandard or worse.  Management may also elect to measure an individual loan for impairment if less than $100,000 on a case by case basis.
Mortgage loans on one-to-four family properties and all consumer loans are large groups of smaller-balance homogeneous loans and are measured for impairment collectively. Loans that experience insignificant payment delays, which are defined as 90 days or less, generally are not classified as impaired.  Management determines the significance of payment delays on a case-by-case basis taking into consideration all circumstances surrounding the loan and the borrower including the length of the delay, the borrower’s prior payment record, and the amount of shortfall in relation to the principal and interest owed.  Interest income for impaired loans is recorded consistent to the Banks' policy on non-accrual loans.

Modifications
The loan portfolio also includes certain loans that have been modified in a Troubled Debt Restructuring (TDR), where economic concessions have been granted to borrowers who have experienced or are expected to experience financial difficulties.  These concessions typically result from loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance, or other actions.  Certain TDRs are classified as nonperforming at the time of restructure and may only be returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period, generally six months.
Loan modifications that are considered TDRs completed during the twelve months ended December 31, 2014 and 2013 were as follows:
	Year Ended December 31,
	2014											2013

There was one commercial real estate loan modifications considered a troubled debt restructurings made during the twelve months previous to December 31, 2014 that defaulted during the twelve month period ending December 31, 2014.  However, that loan was paid off in the fourth quarter of 2014. There were four commercial real estate loan modifications considered troubled debt restructurings with a recorded investment of $1,884,000 made during the twelve months previous to December 31, 2013 that defaulted during the twelve month period ending December 31, 2013.
Internal Risk Ratings
Management uses a ten point internal risk rating system to monitor the credit quality of the overall loan portfolio. The first six categories are considered not criticized, and are aggregated as “Pass” rated. The criticized rating categories utilized by management generally follow bank regulatory definitions. The Special Mention category includes assets that are currently protected but are potentially weak, resulting in an undue and unwarranted credit risk, but not to the point of justifying a Substandard classification. Loans in the Substandard category have well-defined weaknesses that jeopardize the liquidation of the debt, and have a distinct possibility that some loss will be sustained if the weaknesses are not corrected. All loans greater than 90 days past due are evaluated for Substandard classification.  Loans in the Doubtful category exhibit the same weaknesses found in the Substandard loans, however, the weaknesses are more pronounced.  Such loans are static and collection in full is improbable.  However, these loans are not yet rated as loss because certain events may occur which would salvage the debt.  Loans classified Loss are considered uncollectible and charge-off is imminent.
To help ensure that risk ratings are accurate and reflect the present and future capacity of borrowers to repay a loan as agreed, the Banks have a structured loan rating process with several layers of internal and external oversight.  Generally, consumer and residential mortgage loans are included in the pass category unless a specific action, such as bankruptcy, repossession, or death occurs to raise awareness of a possible credit event.  An external annual loan review of large commercial relationships is performed, as well as a sample of smaller transactions.  During 2014, the threshold for the annual loan review was commercial relationships $1,000,000 or greater for JSSB and $1,450,000 or greater for Luzerne. Confirmation of the appropriate risk category is included in the review.  Detailed reviews, including plans for resolution, are performed on loans classified as Substandard, Doubtful, or Loss on a quarterly basis.
The following table presents the credit quality categories identified above as of December 31, 2014 and 2013:

Allowance for Loan Losses
An allowance for loan losses (“ALL”) is maintained to absorb losses from the loan portfolio.  The ALL is based on management’s continuing evaluation of the risk characteristics and credit quality of the loan portfolio, assessment of current economic conditions, diversification and size of the portfolio, adequacy of collateral, past and anticipated future loss experience, and the amount of non-performing loans.
The Banks' methodology for determining the ALL is based on the requirements of ASC Section 310-10-35 for loans individually evaluated for impairment (previously discussed) and ASC Subtopic 450-20 for loans collectively evaluated for impairment, as well as the Interagency Policy Statements on the Allowance for Loan and Lease Losses and other bank regulatory guidance.  The total of the two components represents the Banks' ALL.
Loans that are collectively evaluated for impairment are analyzed with general allowances being made as appropriate.  Allowances are segmented based on collateral characteristics previously disclosed, and consistent with credit quality monitoring.  Loans that are collectively evaluated for impairment are grouped into two classes for evaluation.  A general allowance is determined for “Pass” rated credits, while a separate pool allowance is provided for “Criticized” rated credits that are not individually evaluated for impairment.
For the general allowances historical loss trends are used in the estimation of losses in the current portfolio.  These historical loss amounts are modified by other qualitative factors.  A historical charge-off factor is calculated utilizing a twelve quarter moving average.  However, management may adjust the moving average time frame by up to four quarters to adjust for variances in the economic cycle. Management has identified a number of additional qualitative factors which it uses to supplement the historical charge-off factor because these factors are likely to cause estimated credit losses associated with the existing loan pools to differ from historical loss experience.  The additional factors that are evaluated quarterly and updated using information obtained from internal, regulatory, and governmental sources are: national and local economic trends and conditions; levels of and trends in delinquency rates and non-accrual loans; trends in volumes and terms of loans; effects of changes in lending policies; experience, ability, and depth of lending staff; value of underlying collateral; and concentrations of credit from a loan type, industry, and/or geographic standpoint.
Loans in the criticized pools, which possess certain qualities or characteristics that may lead to collection and loss issues, are closely monitored by management and subject to additional qualitative factors.  Management also monitors industry loss factors by loan segment for applicable adjustments to actual loss experience.
Management reviews the loan portfolio on a quarterly basis in order to make appropriate and timely adjustments to the ALL.  When information confirms all or part of specific loans to be uncollectible, these amounts are promptly charged off against the ALL.

The Company grants commercial, industrial, residential, and installment loans to customers throughout north-central and north-eastern Pennsylvania. Although the Company has a diversified loan portfolio at December 31, 2014 and 2013, a substantial portion of its debtors’ ability to honor their contracts is dependent on the economic conditions within this region.
The Company has a concentration of loans at December 31, 2014 and 2013 as follows:
	2014			2013
Owners of residential rental properties	16.01	%		15.67	%

	As of December 31, 2014 and 2013 goodwill had a gross carrying value of $17,380,000 and accumulated amortization of $276,000 resulting in a net carrying amount of $17,104,000.
	The gross carrying amount of goodwill is tested for impairment in the third quarter of each fiscal year.  Based on the fair value of the reporting unit, estimated using the expected present value of future cash flows, there was no evidence of impairment of the carrying amount at December 31, 2014 or 2013.
	Identifiable intangibles are amortized to their estimated residual values over the expected useful lives. Such lives are also periodically reassessed to determine if any amortization period adjustments are required.  Since the acquisition, no such adjustments were recorded.  The identifiable intangible assets consist of a core deposit intangible and trade name intangible which are being amortized on an accelerated basis over the useful life of such assets.  The gross carrying amount of the core deposit intangible and trade name intangible at December 31, 2014 was $1,360,000 and $96,000, respectively, with $521,000 and $37,000 accumulated amortization as of that date.
	As of December 31, 2014, the estimated future amortization expense for the core deposit and trade name intangible was:

	The terms of the convertible borrowings allow the FHLB to convert the interest rate to an adjustable rate based on the three month London Interbank Offered Rate (“LIBOR”) at a predetermined anniversary date of the borrowing’s origination, ranging from three months to five years.  If the FHLB converts the interest rate on one of the predetermined dates, the Bank has the ability to pay off the debt on the conversion date and quarterly thereafter without incurring the customary pre-payment penalty.
	The Banks maintain a credit arrangement which includes a revolving line of credit with the FHLB.  Under this credit arrangement, at December 31, 2014 JSSB has a remaining borrowing capacity of $245,776,000 and Luzerne has a remaining capacity of $141,559,000, which are subject to annual renewal and typically incur no service charges.  Under terms of a blanket agreement, collateral for the FHLB borrowings must be secured by certain qualifying assets of each Bank which consist principally of first mortgage loans and mortgage-backed securities.
	In December 2012, JSSB entered in to a capital lease on a piece of land in Lewisburg, Pennsylvania. The carrying amount of the land as of December 31, 2014 and 2013 was $827,000. The present value of minimum lease payments at December 31, 2014 and 2013 was $426,000 and $452,000. The following is a schedule showing the furture minimum lease payments under the capital lease by years and the present value of the minimum lease payments as of December 31, 2014.

	No valuation allowance was established at December 31, 2014 and 2013, because of the Company’s ability to carry back capital losses to recover taxes paid in previous years and certain tax strategies, together with the anticipated future taxable income as evidenced by the Company’s earning potential. The Corporation is no longer subject to federal, state, and local examinations by tax authorities for years before 2011.

	Defined Benefit Pension Plan
	The Company has a noncontributory defined benefit pension plan (the “Plan”) for all employees meeting certain age and length of service requirements that were hired prior to January 1, 2004, at which time entrance into the Plan was frozen.  The benefit accrual for the Plan was subsequently frozen at December 31, 2014. Benefits are based primarily on years of service and the average annual compensation during the highest five consecutive years within the final ten years of employment - up until December 31, 2014 when the benefit accrual was frozen.
	The following table sets forth the obligation and funded status as of December 31, 2014 and 2013:

	Expected long-term return on plan assets	8	%		8	%		8	%
	Rate of compensation increase	3	%		3	%		3	%
	The expected long-term rate of return was estimated using market benchmarks by which the plan assets would outperform the market value in the future, based on historical experience adjusted for changes in asset allocation and expectations for overall lower future returns on similar investments compared to past periods.
	Plan Assets
	The Plan’s weighted-average asset allocations at December 31, 2014 and 2013 by asset category are as follows:
	Asset Category		2014			2013
	Cash		11.54	%		1.48	%
	Fixed income securities		12.46	%		19.78	%
	Equity		76	%		78.74	%
	Total		100	%		100	%
	The investment objective for the Plan is to maximize total return with tolerance for slightly above average risk, meaning the fund is able to tolerate short-term volatility to achieve above-average returns over the long term.
	Asset allocation favors equities, with target allocation of approximately 75% equity securities, 22.5% fixed income securities and 2.5% cash.  Due to volatility in the market, the target allocation is not always desirable and asset allocations will fluctuate between the acceptable ranges.  The equity portfolio’s exposure is primarily in mid and large capitalization domestic equities with limited exposure to small capitalization and international stocks.
	It is management’s intent to give the investment managers flexibility, within the overall guidelines, with respect to investment decisions and their timing. However, certain investments require specific review and approval by management.  Management is also informed of anticipated, significant modifications of any previously approved investment, or anticipated use of derivatives to execute investment strategies.
	The following table sets forth by level, within the fair value hierarchy detailed in Note 20 - Fair Value Measurements, the Plan’s assets at fair value as of December 31, 2014 and 2013:

Off Balance Sheet Risk
OFF-BALANCE SHEET RISK	OFF-BALANCE SHEET RISK
	The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit.  These instruments involve, to varying degrees, elements of credit, interest rate, or liquidity risk in excess of the amount recognized in the Consolidated Balance Sheet. The contract amounts of these instruments express the extent of involvement the Company has in particular classes of financial instruments.
	The Company’s exposure to credit loss from nonperformance by the other party to the financial instruments for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments.  The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments.  The Company may require collateral or other security to support financial instruments with off-balance sheet credit risk.
	Financial instruments whose contract amounts represent credit risk are as follows at December 31, 2014 and 2013:
	(In Thousands)	2014		2013
	Commitments to extend credit	$	235,940	$	185,415
	Standby letters of credit	7,490		4,379
	Commitments to extend credit are legally binding agreements to lend to customers.  Commitments generally have fixed expiration dates or other termination clauses and may require payment of fees.  Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future liquidity requirements.  The Company evaluates each customer’s credit worthiness on a case-by-case basis.  The amount of collateral obtained, if deemed necessary by the Company, on an extension of credit is based on management’s credit assessment of the counterparty.
	Standby letters of credit represent conditional commitments issued by the Company to guarantee the performance of a customer to a third party.  These instruments are issued primarily to support bid or performance related contracts.  The coverage period for these instruments is typically a one year period with an annual renewal option subject to prior approval by management.  Fees earned from the issuance of these letters are recognized upon expiration of the coverage period.  For secured letters of credit, the collateral is typically Bank deposit instruments or customer business assets.

CAPITAL_REQUIREMENTS

CAPITAL REQUIREMENTS	12 Months Ended

Banking and Thrift [Abstract]
CAPITAL REQUIREMENTS	CAPITAL REQUIREMENTS
	Federal regulations require the Company and the Banks to maintain minimum amounts of capital.  Specifically, each is required to maintain certain minimum dollar amounts and ratios of Total and Tier 1 capital to risk-weighted assets and of Tier 1 capital to average total assets.
	In addition to the capital requirements, the Federal Deposit Insurance Corporation Improvement Act (“FDICIA”) established five capital categories ranging from “well capitalized” to “critically undercapitalized.”  Should any institution fail to meet the requirements to be considered “adequately capitalized,” it would become subject to a series of increasingly restrictive regulatory actions.
	As of December 31, 2014 and 2013, the FDIC categorized the Banks as well capitalized under the regulatory framework for prompt corrective action.  To be classified as a well capitalized financial institution, Total risk-based, Tier 1 risk-based, and Tier 1 leverage capital ratios must be at least 10%, 6%, and 5%, respectively.
	The Company’s and the Banks' actual capital ratios are presented in the following tables, which shows that the Company and both Banks met all regulatory capital requirements.

REGULATORY RESTRICTIONS	REGULATORY RESTRICTIONS
	The Pennsylvania Banking Code restricts the availability of capital funds for payment of dividends by all state-chartered banks. Accordingly, at December 31, 2014, the balance in the additional paid in capital account totaling $11,657,000 for JSSB and $42,214,000 for Luzerne Bank is unavailable for dividends.
	The Banks are subject to regulatory restrictions, which limit the ability to loan funds to Penns Woods Bancorp, Inc.  At December 31, 2014, the regulatory lending limit amounted to approximately $16,985,000.
	Cash and Due from Banks
	Jersey Shore State Bank and Luzerne Bank had no reserve requirements by the district Federal Reserve Bank at December 31, 2014 or 2013; however, if they did they would be reported with cash and due from banks. The required reserves are computed by applying prescribed ratios to the classes of average deposit balances.  These are held in the form of cash on hand and a balance maintained directly with the Federal Reserve Bank.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS
	The following disclosures show the hierarchal disclosure framework associated with the level of pricing observations utilized in measuring assets and liabilities at fair value. The three broad levels of pricing observations are as follows:
	Level I:	Quoted prices are available in active markets for identical assets or liabilities as of the reported date.
	Level II:	Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reported date. The nature of these assets and liabilities includes items for which quoted prices are available but traded less frequently, and items that are fair valued using other financial instruments, the parameters of which can be directly observed.
	Level III:	Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.
	This hierarchy requires the use of observable market data when available.
	The following table presents the assets reported on the balance sheet at their fair value on a recurring basis as of December 31, 2014 and 2013, by level within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

	Other real estate owned	$	1,898	Appraisal of collateral (1)
	(1) Appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses.
	The significant unobservable inputs used in the fair value measurement of the Company’s impaired loans using the discounted cash flow valuation technique include temporary changes in payment amounts and the probability of default.  Significant increases (decreases) in payment amounts would result in significantly higher (lower) fair value measurements.  The probability of default is 0% for impaired loans using the discounted cash flow valuation technique because all defaulted impaired loans are valued using the appraisal of collateral valuation technique.
	The significant unobservable input used in the fair value measurement of the Company’s impaired loans using the appraisal of collateral valuation technique include appraisal adjustments, which are adjustments to appraisals by management for qualitative factors such as economic conditions and estimated liquidation expenses.  The significant unobservable input used in the fair value measurement of the Company’s other real estate owned are the same inputs used to value impaired loans using the appraisal of collateral valuation technique.

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE OF FINANCIAL INSTRUMENTS
	The Company is required to disclose fair values for its financial instruments.  Fair values are made at a specific point in time, based on relevant market information and information about the financial instrument.  These fair values do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument.  Also, it is the Company’s general practice and intention to hold most of its financial instruments to maturity and not to engage in trading or sales activities.  Because no market exists for a significant portion of the Company’s financial instruments, fair values are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors.  These fair values are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision.  Changes in assumptions can significantly affect the fair values.
	Fair values have been determined by the Company using historical data and an estimation methodology suitable for each category of financial instruments.  The Company’s fair values, methods, and assumptions are set forth below for the Company’s other financial instruments.
	As certain assets and liabilities, such as deferred tax assets, premises and equipment, and many other operational elements of the Company, are not considered financial instruments but have value, the fair value of financial instruments would not represent the full market value of the Company.
	The fair values of the Company’s financial instruments are as follows at December 31, 2014 and 2013:

	Cash and Cash Equivalents, Loans Held for Sale, Accrued Interest Receivable, Short-term Borrowings, and Accrued Interest Payable:
	The fair value is equal to the carrying value.
	Investment Securities:
	The fair value of investment securities available for sale is equal to the available quoted market price. If no quoted market price is available, fair value is determined by using the quoted market price for similar securities.  Regulatory stocks’ fair value is equal to the carrying value.
	Loans:
	Fair values are determined for portfolios of loans with similar financial characteristics.  Loans are segregated by type such as commercial, commercial real estate, residential real estate, construction real estate, and other consumer.  Each loan category is further segmented into fixed and adjustable rate interest terms and by performing and nonperforming categories.
	The fair value of performing loans is calculated by discounting scheduled cash flows through the estimated maturity using market discount rates that reflect the credit and interest rate risk inherent in the loan.  The estimate of maturity is based on the Company’s historical experience with repayments for each loan classification, modified, as required, by an estimate of the effect of current economic and lending conditions.
	Fair value for significant nonperforming loans is based on recent external appraisals.  If appraisals are not available, estimated cash flows are discounted using a rate commensurate with the risk associated with the estimated cash flows.  Assumptions regarding credit risk, cash flows, and discounted rates are judgmentally determined using available market information and specific borrower information.
	Bank-Owned Life Insurance:
	The fair value is equal to the cash surrender value of the life insurance policies.
	Deposits:
	The fair value of deposits with no stated maturity, such as noninterest-bearing demand deposits, savings, NOW, and money market accounts, is equal to the amount payable on demand as of December 31, 2014 and 2013.  The fair value of certificates of deposit is based on the discounted value of contractual cash flows.
	The fair values above do not include the benefit that results from the low-cost funding provided by the deposit liabilities compared to the cost of borrowing funds in the market, commonly referred to as the core deposit intangible.
	Long Term Borrowings:
	The fair value of long term borrowings is based on the discounted value of contractual cash flows.
	Commitments to Extend Credit, Standby Letters of Credit, and Financial Guarantees Written:
	There is no material difference between the notional amount and the fair value of off-balance sheet items at December 31, 2014 and 2013.  The contractual amounts of unfunded commitments and letters of credit are presented in Note 17.

ACQUISITION_OF_LUZERNE_NATIONA

ACQUISITION OF LUZERNE NATIONAL BANK CORPORATION	12 Months Ended
	Dec. 31, 2014
Business Combinations [Abstract]
ACQUISITION OF LUZERNE NATIONAL BANK CORPORATION	ACQUISITION OF LUZERNE NATIONAL BANK CORPORATION
	On June 1, 2013, the Company closed on a merger transaction pursuant to which Penns Woods Bancorp, Inc. acquired Luzerne National Bank Corporation in a stock and cash transaction.  The acquisition extended the Company’s footprint into Luzerne and Lackawanna Counties, Pennsylvania.
	Luzerne National Bank Corporation was the holding company for Luzerne Bank, a Pennsylvania bank that conducted its business from a main office in Luzerne, Pennsylvania with eight branch offices in Luzerne County and one loan production office in Lackawanna County, all in northeastern Pennsylvania. Since June 1, 2013, the loan production office in Lackawanna County has been closed.
	Under the terms of the merger agreement, the Company acquired all of the outstanding shares of Luzerne National Bank Corporation for a total purchase price of approximately $42,612,000.  As a result of the acquisition, the Company issued 978,977 common shares, or 20.37% of the total shares outstanding as of December 31, 2014, to former shareholders of Luzerne National Bank Corporation.  Luzerne Bank is operating as an independent bank under the Penns Woods Bancorp, Inc. umbrella.
	The acquired assets and assumed liabilities were measured at estimated fair values. Management made significant estimates and exercised significant judgment in accounting for the acquisition.  Management measured loan fair values based on loan file reviews, appraised collateral values, expected cash flows, and historical loss factors of Luzerne Bank.  Real estate acquired through foreclosure was primarily valued based on appraised collateral values.  The Company also recorded an identifiable intangible asset representing the core deposit base of Luzerne Bank based on management’s evaluation of the cost of such deposits relative to alternative funding sources.  The Company also recorded an identifiable intangible asset representing the trade name of Luzerne Bank based on management’s evaluation of the value of the name in the market.  Management used significant estimates including the average lives of depository accounts, future interest rate levels, and the cost of servicing various depository products. Management used market quotations to determine the fair value of investment securities.
	The business combination resulted in the acquisition of loans with and without evidence of credit quality deterioration. Luzerne Bank’s loans were deemed impaired at the acquisition date if the Company did not expect to receive all contractually required cash flows due to concerns about credit quality.  Such loans were fair valued and the difference between contractually required payments at the acquisition date and cash flows expected to be collected was recorded as a non-accretable difference. At the acquisition date, the Company recorded $1,211,000 of purchased credit-impaired loans subject to a non-accretable difference of $842,000. The method of measuring carrying value of purchased loans differs from loans originated by the Company (originated loans), and as such, the Company identifies purchased loans and purchased loans with a credit quality discount and originated loans at amortized cost.
	Luzerne’s loans without evidence of credit deterioration were fair valued by discounting both expected principal and interest cash flows using an observable discount rate for similar instruments that a market participant would consider in determining fair value.  Additionally, consideration was given to management’s best estimates of default rates and payment speeds.  At acquisition, Luzerne’s loan portfolio without evidence of deterioration totaled $249,789,000 and was recorded at a fair value of $249,500,000.

OPERATIONS_AND_SUMMARY_OF_SIGN1

OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation
	The accompanying consolidated financial statements include the accounts of Penns Woods Bancorp, Inc. and its wholly owned subsidiaries, Jersey Shore State Bank (“JSSB”), Luzerne Bank ("Luzerne" collectively with JSSB "Banks"), Woods Real Estate Development Co., Inc., Woods Investment Company, Inc., and The M Group Inc. D/B/A The Comprehensive Financial Group (“The M Group”), a wholly owned subsidiary of the Bank (collectively, the “Company”).  All significant intercompany balances and transactions have been eliminated.
Use of Estimates	Use of Estimates
	The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results may differ from those estimates.
	Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, valuation of net deferred tax assets, impairment of goodwill, other than temporary impairment of debt and equity securities, fair value of financial instruments, and the valuation of real estate acquired through, or in lieu of, foreclosure on settlement of debt.
Cash and Cash Equivalents	Cash and Cash Equivalents
	Cash and cash equivalents include cash on hand and in banks and federal funds sold.  Interest-earning deposits mature within 90 days and are carried at cost.  Net cash flows are reported for loan, deposit, and short-term borrowing transactions.
Restrictions on Cash and Cash Equivalents	Restrictions on Cash and Cash Equivalents
	Based on deposit levels, the Banks must maintain cash and other reserves with the Federal Reserve Bank of Philadelphia (FRB).
Investment Securities	Investment Securities
	Investment securities are classified at the time of purchase, based on management’s intention and ability, as securities held to maturity or securities available for sale.  Debt securities acquired with the intent and ability to hold to maturity are stated at cost, adjusted for amortization of premium and accretion of discount, which are computed using the interest method and recognized as adjustments of interest income. Certain other debt securities have been classified as available for sale to serve principally as a source of liquidity.  Unrealized holding gains and losses for available for sale securities are reported as a separate component of shareholders’ equity, net of tax, until realized.  Realized security gains and losses are computed using the specific identification method for debt securities and the average cost method for marketable equity securities.  Interest and dividends on investment securities are recognized as income when earned.
	Securities are periodically reviewed for other-than-temporary impairment based upon a number of factors, including, but not limited to, the length of time and extent to which the fair value has been less than cost, the financial condition of the underlying issuer, the ability of the issuer to meet contractual obligations, the likelihood of the security’s ability to recover any decline in its fair value, whether it is more likely than not that the Company would be required to sell the security before its anticipated recovery in fair value, and a review of the Company’s capital adequacy, interest rate risk position, and liquidity. The assessment of a security’s ability to recover any decline in fair value, the ability of the issuer to meet contractual obligations, and management’s intent and ability requires considerable judgment. A decline in value that is considered to be other-than-temporary is recorded as a loss within non-interest income in the Consolidated Statement of Income.
	Investment securities fair values are based on observed market prices.  Certain investment securities do not have observed bid prices and their fair value is based on instruments with similar risk elements. Since regulatory stock is redeemable at par, the Company carries it at cost.
Loans	Loans
	Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff generally are stated at the principal amount outstanding, net of deferred fees and discounts, unamortized loan fees and costs, and the allowance for loan losses. Interest on loans is recognized as income when earned on the accrual method.  The Company’s general policy has been to stop accruing interest on loans when it is determined a reasonable doubt exists as to the collectability of additional interest. Income is subsequently recognized only to the extent that cash payments are received provided the loan is not delinquent in payment and, in management’s judgment, the borrower has the ability and intent to make future principal payments.  Otherwise, payments are applied to the unpaid principal balance of the loan.  Loans are restored to accrual status if certain conditions are met, including but not limited to, the repayment of all unpaid interest and scheduled principal due, ongoing performance consistent with the contractual agreement, and the future expectation of continued, timely payments.
	Loan origination and commitment fees as well as certain direct loan origination costs are being deferred and amortized as an adjustment to the related loan’s yield over the contractual lives of the related loans.
Allowance for Loan Losses	Allowance for Loan Losses
	The allowance for loan losses represents the amount which management estimates is adequate to provide for probable losses inherent in its loan portfolio, as of the Consolidated Balance Sheet date.  The allowance method is used in providing for loan losses.  Accordingly, all loan losses are charged to the allowance and all recoveries are credited to it.  The allowance for loan losses is established through a provision for loan losses charged to operations.  The provision for loan losses is based upon management’s quarterly review of the loan portfolio.  The purpose of the review is to assess loan quality, identify impaired loans, analyze delinquencies, ascertain loan growth, evaluate potential charge-offs and recoveries, and assess general economic conditions in the markets served.  An external independent loan review is also performed annually for the Bank.  Management remains committed to an aggressive program of problem loan identification and resolution.
	The allowance is calculated by applying loss factors to outstanding loans by type, excluding loans for which a specific allowance has been determined.  Loss factors are based on management’s consideration of the nature of the portfolio segments, changes in mix and volume of the loan portfolio, historical loan loss experience, and general economic conditions.  In addition, management considers industry standards and trends with respect to nonperforming loans and its knowledge and experience with specific lending segments.
	Although management believes that it uses the best information available to make such determinations and that the allowance for loan losses is adequate at December 31, 2014, future adjustments could be necessary if circumstances or economic conditions differ substantially from the assumptions used in making the initial determinations.  A downturn in the local economy, rising unemployment, or negative performance trends in financial information from borrowers could be indicators of subsequent increased levels of nonperforming assets and possible charge-offs, which would normally require increased loan loss provisions. An integral part of the periodic regulatory examination process is the review of the adequacy of the Banks' loan loss allowance. The regulatory agencies could require the Banks, based on their evaluation of information available at the time of their examination, to provide additional loan loss provisions to further supplement the allowance.
	Impaired loans are commercial and commercial real estate loans for which it is probable the Banks will not be able to collect all amounts due according to the contractual terms of the loan agreement.  The Banks individually evaluate such loans for impairment and do not aggregate loans by major risk classifications.  The definition of “impaired loans” is not the same as the definition of “nonaccrual loans,” although the two categories overlap.  The Banks may choose to place a loan on nonaccrual status due to payment delinquency or uncertain collectability, while not classifying the loan as impaired if the loan is not a commercial or commercial real estate loan. Factors considered by management in determining impairment include payment status and collateral value.  The amount of impairment for these types of loans is determined by the difference between the present value of the expected cash flows related to the loan, using the original interest rate, and its recorded value, or as a practical expedient in the case of collateralized loans, the difference between the fair value of the collateral and the recorded amount of the loans.  When foreclosure is probable, impairment is measured based on the fair value of the collateral.
	Mortgage loans on one-to-four family properties and all consumer loans are large groups of smaller-balance homogeneous loans and are measured for impairment collectively.  Loans that experience insignificant payment delays, which are defined as 90 days or less, generally are not classified as impaired.  Management determines the significance of payment delays on a case-by-case basis taking into consideration all circumstances surrounding the loan and the borrower including the length of the delay, the borrower’s prior payment record, and the amount of shortfall in relation to the principal and interest owed.
Loan Charge-off Policies	Loan Charge-off Policies
	Loans are generally fully or partially charged down to the fair value of collateral securing the asset when:
	•	management judges the asset to be uncollectible;
	•	repayment is deemed to be protracted beyond reasonable time frames;
	•	the asset has been classified as a loss by either the internal loan review process or external examiners;
	•	the borrower has filed bankruptcy and the loss becomes evident due to a lack of assets; or
	•	the loan is 180 days past due unless both well secured and in the process of collection.
Troubled Debt Restructurings	Troubled Debt Restructurings
	In situations where, for economic or legal reasons related to a borrower’s financial difficulties, management may grant a concession for other than an insignificant period of time to the borrower that would not otherwise be considered, the related loan is classified as a troubled debt restructuring (TDR). Management strives to identify borrowers in financial difficulty early and work with them to modify to more affordable terms before their loan reaches nonaccrual status. These modified terms may include rate reductions, principal forgiveness, payment forbearance, and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral. In cases where borrowers are granted new terms that provide for a reduction of either interest or principal, management measures any impairment on the restructuring as noted above for impaired loans.
	In addition to the allowance for the pooled portfolios, management has developed a separate allowance for loans that are identified as impaired through a TDR. These loans are excluded from pooled loss forecasts and a separate reserve is provided under the accounting guidance for loan impairment. Consumer loans whose terms have been modified in a TDR are also individually analyzed for estimated impairment.
Loans Held for Sale	Loans Held for Sale
	In general, fixed rate residential mortgage loans originated by the Banks are held for sale and are carried at cost due to their short holding period, which can range from less than two weeks to a maximum of thirty days.  Sold loans are not serviced by the Banks. Proceeds from the sale of loans in excess of the carrying value are accounted for as a gain.  Total gains on the sale of loans are shown as a component of non-interest income within the Consolidated Statement of Income.
Foreclosed Assets	Foreclosed Assets
	Foreclosed assets are carried at the lower of cost or fair value less estimated selling costs.  Prior to foreclosure, the value of the underlying loan is written down to the fair value of the real estate to be acquired by a charge to the allowance for loan losses, if necessary. Any subsequent write-downs are charged against operating expenses.  Net operating expenses and gains and losses realized from disposition are included in non-interest expense and income, respectively, within the Consolidated Statement of Income.
Premises and Equipment	Premises and Equipment
	Land is carried at cost.  Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed using straight-line and accelerated methods over the estimated useful lives of the related assets, which range from five to ten years for furniture, fixtures, and equipment and fifteen to forty years for buildings and improvements.  Costs incurred for routine maintenance and repairs are charged to operations as incurred.  Costs of major additions and improvements are capitalized.
Bank-Owned Life Insurance	Bank-Owned Life Insurance
	The Company has purchased life insurance policies on certain officers and directors.  Bank-owned life insurance is recorded at its cash surrender value, or the amount that can be realized.  Increases in the cash surrender value are recognized as a component of non-interest income within the Consolidated Statement of Income.
Goodwill	Goodwill
	The Company performs an annual impairment analysis of goodwill for its purchased subsidiaries, Luzerne and The M Group.
Intangible Assets	Intangible Assets
	At December 31, 2014, the Company had intangible assets of $1,456,000 as a result of the acquisition of Luzerne National Bank Corporation, which is net of accumulated amortization of $558,000. These intangible assets will continue to be amortized using the sum-of-the-years digits method of amortization over ten years.
Investments in Limited Partnerships	Investments in Limited Partnerships
	The Company is a limited partner in four partnerships at December 31, 2014 that provide low income elderly housing in the Company’s geographic market area. The carrying value of the Company’s investments in limited partnerships was $1,560,000 at December 31, 2014 and $2,221,000 at December 31, 2013. One investment is fully amortized, while the other three are being amortized over the ten-year tax credit receipt period utilizing the straight-line method.
Off-Balance Sheet Financial Instruments	Off-Balance Sheet Financial Instruments
	In the ordinary course of business, the Company enters into off-balance sheet financial instruments. Those instruments consist of commitments to extend credit and standby letters of credit. When those instruments are funded or become payable, the Company reports the amounts in its financial statements.
Advertising Cost	Advertising Cost
	Advertising costs are generally expensed as incurred.
Income Taxes	Income Taxes
	The Company prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met.
	Deferred tax assets and liabilities result from temporary differences in financial and income tax methods of accounting, and are reflected at currently enacted income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes.  The Company analyzed its deferred tax asset position and determined that there was not a need for a valuation allowance due to the Company’s ability to generate future ordinary and capital taxable income.
	The Company when applicable recognizes interest and penalties on income taxes as a component of income tax provision.
Earnings Per Share	Earnings Per Share
	The Company provides dual presentation of basic and diluted earnings per share.  Basic earnings per share is calculated utilizing net income as reported in the numerator and weighted average shares outstanding in the denominator.  The computation of diluted earnings per share differs in that the dilutive effects of any stock options are adjusted in the denominator.
Employee Benefits	Employee Benefits
	Pension and employee benefits include contributions, determined actuarially, to a defined benefit retirement plan covering the eligible employees of JSSB.  The plan is funded on a current basis to the extent that it is deductible under existing federal tax regulations.  Pension and other employee benefits also include contributions to a defined contribution Section 401(k) plan covering eligible employees.  Contributions matching those made by eligible employees are funded throughout the year. In addition, an elective contribution is made annually at the discretion of the board of directors for the employees of JSSB.
The M Group Products and Income Recognition	The M Group Products and Income Recognition
	The M Group product line is comprised primarily of annuities, life insurance, and mutual funds.  The revenues generated from life insurance sales are commission only, as The M Group does not underwrite the policies.  Life insurance sales include permanent and term policies with the majority of the policies written being permanent.  Term life insurance policies are written for 10, 15, 20, and 30 year terms with the majority of the policies being written for 20 years.  None of these products are offered as an integral part of lending activities.
	Commissions from the sale of annuities are recognized at the time notice is received from the third party broker/dealer or an insurance company that the transaction has been accepted and approved, which is also the time when commission income is received.
	Life insurance commissions are recognized at varying points based on the payment option chosen by the customer.  Commissions from monthly and annual payment plans are recognized at the start of each annual period for the life insurance, while quarterly and semi-annual premium payments are recognized quarterly and semi-annually when the earnings process is complete.  For example, semi-annual payments on the first of January and July would result in commission income recognition on the first of January and July, while payments on the first of January, April, July, and October would result in commission income recognition on those dates. The potential for chargebacks only exists for those policies on a monthly payment plan since income is recognized at the beginning of the annual coverage period versus at the time of each monthly payment.  No liability is maintained for chargebacks as these are removed from income at the time of the occurrence.
Accumulated Other Comprehensive Income	Accumulated Other Comprehensive Income (Loss)
	The Company is required to present accumulated other comprehensive income (loss) in a full set of general-purpose financial statements for all periods presented. Accumulated other comprehensive income (loss) is comprised of unrealized holding gains (losses) on the available for sale securities portfolio and the unrecognized components of net periodic benefit costs of the defined benefit pension plan.
Segment Reporting	Segment Reporting
	The Company has determined that its only reportable segment is Community Banking.
Reclassification of Comparative Amounts	Reclassification of Comparative Amounts
	Certain items previously reported have been reclassified to conform to the current year’s reporting format.  Such reclassifications did not affect net income or shareholders’ equity.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In January 2014, FASB issued ASU 2014-01, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects. The amendments in this update permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). The amendments in this update should be applied retrospectively to all periods presented. A reporting entity that uses the effective yield method to account for its investments in qualified affordable housing projects before the date of adoption may continue to apply the effective yield method for those preexisting investments. The amendments in this update are effective for public business entities for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2014. Early adoption is permitted. This ASU did not have an impact on the Company’s financial statements.
	In January 2014, the FASB issued ASU 2014-04, Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The amendments in this update clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendments require interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor, and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The amendments in this update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. An entity can elect to adopt the amendments in this update using either a modified retrospective transition method or a prospective transition method. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (a new revenue recognition standard). The update’s core principle is that a company will recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, this update specifies the accounting for certain costs to obtain or fulfill a contract with a customer and expands disclosure requirements for revenue recognition. This update is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.
	In June 2014, the FASB issued ASU 2014-11, Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. The amendments in this update change the accounting for repurchase-to-maturity transactions to secured borrowing accounting. For repurchase financing arrangements, the amendments require separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. The amendments also require enhanced disclosures. The accounting changes in this update are effective for the first interim or annual period beginning after December 15, 2014. An entity is required to present changes in accounting for transactions outstanding on the effective date as a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. Earlier application is prohibited. The disclosure for certain transactions accounted for as a sale is required to be presented for interim and annual periods beginning after December 15, 2014, and the disclosure for repurchase agreements, securities lending transactions, and repurchase-to-maturity transactions accounted for as secured borrowings is required to be presented for annual periods beginning after December 15, 2014, and for interim periods beginning after March 15, 2015. The disclosures are not required to be presented for comparative periods before the effective date. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.
	In June 2014, the FASB issued ASU 2014-12, Compensation-Stock Compensation (Topic 718): Accounting for Share-Based Payments when the Terms of an Award Provide that a Performance Target Could Be Achieved After the Requisite Service Period. The amendments require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. The amendments in this update are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Earlier adoption is permitted. Entities may apply the amendments in this update either (a) prospectively to all awards granted or modified after the effective date or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. If retrospective transition is adopted, the cumulative effect of applying this update as of the beginning of the earliest annual period presented in the financial statements should be recognized as an adjustment to the opening retained earnings balance at that date. Additionally, if retrospective transition is adopted, an entity may use hindsight in measuring and recognizing the compensation cost. This ASU did not have a significant impact on the Company’s financial statements.
	In August 2014, the FASB issued ASU 2014-14, Receivables - Troubled Debt Restructurings by Creditors (Subtopic 310-40). The amendments in this update require that a mortgage loan be de-recognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: (1) the loan has a government guarantee that is not separable from the loan before foreclosure, (2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim, and (3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The amendments in this update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. This ASU did not have a significant impact on the Company’s financial statements.
	In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40). The amendments in this update provide guidance in accounting principles generally accepted in the United States of America about management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. The amendments in this update are effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. This ASU is not expected to have a significant impact on the Company’s financial statements.
	In November 2014, the FASB issued ASU 2014-17, Business Combinations (Topic 805): Pushdown Accounting. The amendments in this update apply to the separate financial statements of an acquired entity and its subsidiaries that are a business or nonprofit activity (either public or nonpublic) upon the occurrence of an event in which an acquirer (an individual or an entity) obtains control of the acquired entity. An acquired entity may elect the option to apply pushdown accounting in the reporting period in which the change-in-control event occurs. If pushdown accounting is not applied in the reporting period in which the change-in-control event occurs, an acquired entity will have the option to elect to apply pushdown accounting in a subsequent reporting period to the acquired entity's most recent change-in-control event. The amendments in this update are effective on November 18, 2014. After the effective date, an acquired entity can make an election to apply the guidance to future change-in-control events or to its most recent change-in-control event. This update will not have an impact on the Company’s financial statements.
	In January 2015, the FASB issued ASU 2015-01, Income Statement -Extraordinary and Unusual Items, as part of its initiative to reduce complexity in accounting standards. This update eliminates from GAAP the concept of extraordinary items. The amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. A reporting entity may apply the amendments prospectively. A reporting entity also may apply the amendments retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. This update is not expected to have a significant impact on the Company’s financial statements.
