Organization, Consolidation and Presentation Of Financial Statements [Abstract] |
Consolidation, Policy [Policy Text Block] | Principles of Consolidation - The consolidated financial statements include NorthWest Indiana Bancorp (the “Bancorp”), its wholly owned subsidiary, Peoples Bank SB (the “Bank”), and the Bank’s wholly owned subsidiaries, Peoples Service Corporation, NWIN, LLC, and NWIN Funding, Incorporated, and Columbia Development Company, LLC. The Bancorp has no other business activity other than being a holding company for the Bank. The Bancorp’s earnings are dependent upon the earnings of the Bank. Peoples Service Corporation provides insurance and annuity investments to the Bank’s wealth management customers. NWIN, LLC is located in Las Vegas, Nevada and serves as the Bank’s investment subsidiary and parent of a real estate investment trust, NWIN Funding, Inc. NWIN Funding, Inc. was formed as an Indiana Real Estate Investment Trust. The formation of NWIN Funding, Inc. provides the Bancorp with a vehicle that may be used to raise capital utilizing portfolio mortgages as collateral, without diluting stock ownership. In addition, NWIN Funding, Inc. will receive favorable state tax treatment for income generated by its operations. Columbia Development Company is a limited liability company that serves to hold certain real estate properties that are acquired through foreclosure. All significant inter-company accounts and transactions have been eliminated in consolidation.
Use of Estimates, Policy [Policy Text Block] | Use of Estimates - Preparing financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period, as well as the disclosures provided. Actual results could differ from those estimates. Estimates associated with the allowance for loan losses, mortgage servicing rights, fair values of foreclosed real estate, financial instruments and investment securities, and the status of contingencies are particularly susceptible to material change in the near term.
Concentration Risk, Credit Risk, Policy [Policy Text Block] | Concentrations of Credit Risk - The Bancorp grants residential, commercial real estate, commercial business and installment loans to customers primarily in Lake County, in northwest Indiana. The Bancorp is also an active lender in Porter County, and to a lesser extent, LaPorte, Newton, and Jasper counties in Indiana, and Lake, Cook and Will counties in Illinois. Substantially all loans are secured by specific items of collateral including residences, commercial real estate, business assets, and consumer assets.
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash Flow Reporting - For purposes of the statements of cash flows, the Bancorp considers cash on hand, noninterest bearing deposits in other financial institutions, all interest-bearing deposits in other financial institutions with original maturities of ninety days or less, and federal funds sold to be cash and cash equivalents. The Bancorp reports net cash flows for customer loan and deposit transactions and short-term borrowings with maturities of 90 days or less.
Marketable Securities, Policy [Policy Text Block] | Securities - The Bancorp classifies securities into held-to-maturity, available-for-sale, or trading categories. Held-to-maturity securities are those which management has the positive intent and the Bancorp has the ability to hold to maturity, and are reported at amortized cost. Available-for-sale securities are those the Bancorp may decide to sell if needed for liquidity, asset-liability management or other reasons. Available-for-sale securities are reported at fair value, with unrealized gains and losses reported in other comprehensive income, net of tax. During 2011, the Bancorp transferred the balance of its held-to-maturity securities to the available-for-sale classification. The Bancorp does not have a trading portfolio. Realized gains and losses resulting from the sale of securities recorded on the trade date are computed by the specific identification method. Interest and dividend income, adjusted by amortization of premiums or discounts on a level yield method, are included in earnings. Securities are reviewed for other-than-temporary impairment on a quarterly basis. The Bancorp considers the following factors when determining an other-than-temporary impairment for a security: the length of time and the extent to which the market value has been less than amortized cost; the financial condition and near-term prospects of the issuer; the underlying fundamentals of the relevant market and the outlook for such market for the near future; and an assessment of whether the Bancorp has (1) the intent to sell the debt security or (2) it is more likely than not that the Bancorp will be required to sell the debt security before its anticipated market recovery. If either of these conditions are met, management will recognize other-than-temporary impairment. If, in management’s judgment, an other-than-temporary impairment exists, the cost basis of the security will be written down for the credit loss, and the unrealized credit loss will be transferred from accumulated other comprehensive loss as an immediate reduction of current earnings.
Finance, Loan and Lease Receivables, Held-for-sale, Policy [Policy Text Block] | Loans Held-for-Sale - Mortgage loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair market value, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Mortgage loans held-for-sale can be sold with servicing rights retained or released. The carrying value of mortgage loans sold is reduced by the amount allocated to the servicing rights. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold.
Loans and Loan Income [Policy Text Block] | Loans and Loan Income - Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of unearned interest, net deferred loan fees and costs, and an allowance for loan losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the level-yield method without anticipating prepayments. The accrual of interest income on mortgage and commercial loans is discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection. Consumer loans are typically charged-off no later than when they reach 120 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on non-accrual or charged-off status at an earlier date if collection of principal or interest is considered doubtful. Generally, interest accrued but not received for loans placed on non-accrual status is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block] | Allowance for Loan Losses– The allowance for loan losses (allowance) is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged-off. A loan is considered impaired when, based on current information and events, it is probable that the Bancorp will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case by case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis for commercial and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Bancorp does not separately identify individual consumer and residential loans for impairment disclosures.
Federal Home Loan Bank Stock [Policy Text Block] | Federal Home Loan Bank Stock – The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income.
Transfers and Servicing of Financial Assets, Policy [Policy Text Block] | Transfers of Financial Assets - Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Bancorp, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of the right) to pledge or exchange the transferred assets, and (3) the Bancorp does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Property, Plant and Equipment, Policy [Policy Text Block] | Premises and Equipment– Land is carried at cost. Premises and equipment are carried at cost less accumulated depreciation. Premises and related components are depreciated using the straight-line method with useful lives ranging from 26 to 39 years. Furniture and equipment are depreciated using the straight-line method with useful lives ranging from 2 to 10 years.
Real Estate, Policy [Policy Text Block] | Foreclosed Real Estate– Assets acquired through or instead of loan foreclosure are initially recorded at fair value less estimated costs to sell when acquired, establishing a new cost basis. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block] | Long-term Assets– Premises and equipment and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.
Bank Owned Life Insurance [Policy Text Block] | Bank Owned Life Insurance - The Bancorp has purchased life insurance policies on certain key executives. In accordance with accounting for split-dollar life insurance, Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Repurchase Agreements, Valuation, Policy [Policy Text Block] | Repurchase Agreements– Substantially, all repurchase agreement liabilities represent amounts advanced by various customers that are not covered by federal deposit insurance and are secured by securities owned by the Bancorp.
Pension and Other Postretirement Plans, Nonpension Benefits, Policy [Policy Text Block] | Postretirement Benefits Other Than Pensions - The Bancorp sponsors a defined benefit postretirement plan that provides comprehensive major medical benefits to all eligible retirees. Postretirement benefits are accrued based on the expected cost of providing postretirement benefits to employees during the years the employees have rendered service to the Bancorp.
Income Tax, Policy [Policy Text Block] | Income Taxes -Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized.
Loan Commitments, Policy [Policy Text Block] | Loan Commitments and Related Financial Instruments– Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and standby letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Earnings Per Share, Policy [Policy Text Block] | Earnings Per Common Share – Basic earnings per common share is net income divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock options.
Comprehensive Income, Policy [Policy Text Block] | Comprehensive Income – Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on securities available-for-sale and the unrecognized gains and losses on postretirement benefits.
Malpractice Loss Contingency, Policy [Policy Text Block] | Loss Contingencies– Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe such matters currently exist that will have a material effect on the financial statements.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block] | Restrictions on Cash - Cash on hand or on deposit with the Federal Reserve Bank of $572,000 and $559,000 was required to meet regulatory reserve and clearing requirements at December 31, 2012 and 2011, respectively. These balances do not earn interest.
Fair Value of Financial Instruments, Policy [Policy Text Block] | Fair Value of Financial Instruments - Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments and other factors, especially in the absence of broad markets for particular instruments. Changes in assumptions or in market conditions could significantly affect the estimates.
Operating Segments [Policy Text Block] | Operating Segments– While the Bancorp's executive management monitors the revenue streams of the various products and services, the identifiable segments are not material and operations are managed and financial performance is evaluated on a company-wide basis. Accordingly, all of the Bancorp's financial service operations are considered by management to be aggregated in one reportable operating segment.
Reclassification, Policy [Policy Text Block] | Reclassification - Certain amounts appearing in the consolidated financial statements and notes thereto for the year ended December 31, 2011, may have been reclassified to conform to the December 31, 2012 presentation.
New Accounting Pronouncements, Policy [Policy Text Block] | Adoption of New Accounting Pronouncements Update Number 2011-04 – Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS. This update to Fair Value Measurement (Topic 820) results in common fair value measurement and disclosure requirements in U.S. GAAP and IFRS. The amendments in this update explain how to measure fair value. They do not require additional fair value measurements and are not intended to establish valuation standards or affect valuation practices outside of financial reporting. The amendments in this update are to be applied prospectively and are effective during interim and annual periods beginning after December 15, 2011. The Bancorp has adopted this update as of January 1, 2012. Adoption has not resulted in any changes in valuation techniques nor related inputs. Note 15 - Fair Value of Financial Instruments contains expanded disclosure of the level in the fair value hierarchy of inputs that are used in estimating and measuring fair value and information concerning how fair values have been calculated. Update Number 2011-05 – Comprehensive Income (Topic 220): Presentation of Comprehensive Income. This accounting standard update was issued to increase the prominence of items reported in other comprehensive income and to facilitate the convergence of U.S. GAAP and IFRS. Previous U.S. GAAP allowed the Bancorp to present other comprehensive income as part of the statement of changes in stockholders’ equity. This accounting standard update eliminates that option and requires consecutive presentation of the statement of net income and the statement of comprehensive income. The requirement to report comprehensive income either in a single continuous financial statement or in two separate but consecutive financial statements are effective for public entities for reporting periods beginning after December 15, 2011 and will be applied retrospectively. A Consolidated Statement of Comprehensive Income has been included as part of the Bancorp’s audited financial statements, for the twelve months ended December 31, 2012 and 2011. Update Number 2011-12 – Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards update No. 2011-05. This update to Comprehensive Income (Topic 220) defers the requirement to present items that are reclassified from accumulated other comprehensive income to net income separately with their respective components of net income and other comprehensive income. The deferral supersedes only the paragraphs pertaining to how and where reclassification adjustments are presented. The amendments in this update are effective for public entities for reporting periods beginning after December 15, 2011. This update has not had an impact on the Bancorp’s financial statements.
