Allowance for Loan and Lease Losses, Provision for Loss, Net [Abstract] |
Allowance for Loan Losses | Allowance for Loan Losses The Company provides for loan losses through the establishment of an allowance for loan losses which represents an estimated reserve for existing losses in the loan portfolio. A systematic methodology is used for determining the allowance that includes a quarterly review process, risk rating changes, and adjustments to the allowance. The loan portfolio is classified in eight segments and credit risk is evaluated separately in each segment. The appropriate level of the allowance is evaluated continually based on a review of significant loans, with a particular emphasis on nonaccruing, past due, and other loans that may require special attention. Other factors include general conditions in local and national economies; loan portfolio composition and asset quality indicators; and internal factors such as changes in underwriting policies, credit administration practices, experience, ability and depth of lending management, among others. The allowance consists of four elements: (1) specific reserves for loans evaluated individually for impairment; (2) general reserves for each portfolio segment based on historical loan loss experience, (3) qualitative reserves judgmentally adjusted for local and national economic conditions, concentrations, portfolio composition, volume and severity of delinquencies and nonaccrual loans, trends of criticized and classified loans, changes in credit policies, and underwriting standards, credit administration practices, and other factors as applicable for each portfolio segment; and (4) unallocated reserves. All outstanding loans are considered in evaluating the appropriateness of the allowance. A breakdown of the allowance for loan losses as of March 31, 2013, December 31, 2012, and March 31, 2012, by class of financing receivable and allowance element, is presented in the following tables:

Qualitative adjustment factors are taken into consideration when determining reserve estimates. These adjustment factors are based upon our evaluation of various current conditions, including those listed below.
• | General economic conditions.
• | Credit quality trends with emphasis on loan delinquencies, nonaccrual levels and classified loans.
• | Recent loss experience in particular segments of the portfolio.
• | Loan volumes and concentrations, including changes in mix.
• | Other factors, including changes in quality of the loan origination; loan policy changes; changes in credit risk management processes; Bank regulatory and external loan review examination results.
The qualitative amount assigned to the substandard commercial loan segments increased between March 31, 2013 from December 31, 2012 to adjust historical loss averages for the impact of recent write downs taken on a large, atypical credit. Changes to qualitative adjustments for other major portfolio segments were not material at March 31, 2013. The unallocated component of the Allowance for Loan Losses totaled $1,089,000 at March 31, 2013. This compares to $842,000 as of December 31, 2012 and $1,699,000 as of March 31, 2012. Management views these fluctuations in the unallocated portion of the Allowance for Loan Losses to be immaterial. The unallocated amount was deemed appropriate due to the following:
• | In general, the unallocated component is available to cover imprecision or uncertainties to incorporate the range of probable outcomes inherent in estimates used for the allowance, which may change from period to period. An example of this could be a delay in receiving an updated appraisal on a troubled credit.
• | An internal analysis completed on foreclosed property found that when these properties are sold, on average, the selling price is approximately 20% below the appraised value of the property at the time of take in. The unallocated provides for uncertainty in the value of properties when in impaired loan status.
• | Watch-rated commercial loans have increased after bottoming out in late 2009 and early 2010. Additional losses may exist in this portfolio segment, yet are not identifiable at present. The unallocated portion provides some level of support for this.
Commercial loans are comprised of three major classes, commercial real estate loans, commercial construction loans and other commercial loans. Commercial real estate is primarily comprised of loans to small businesses collateralized by owner-occupied real estate, while other commercial is primarily comprised of loans to small businesses collateralized by plant and equipment, commercial fishing vessels and gear, and limited inventory-based lending. Commercial real estate loans typically have a maximum loan-to-value of 75% based upon current appraisal information at the time the loan is made. Municipal loans are comprised of loans to municipalities in Maine for capitalized expenditures, construction projects or tax-anticipation notes. All municipal loans are considered general obligations of the municipality and as such are collateralized by the taxing ability of the municipality for repayment of debt. Construction loans, both commercial and residential, comprise a very small portion of the portfolio, and at 17.0% of capital are well under the regulatory guidance of 100.0% of capital at March 31, 2013. Construction loans and non-owner-occupied commercial real estate loans are at 73.9% of total capital, well under regulatory guidance of 300.0% of capital at March 31, 2013. The process of establishing the allowance with respect to the commercial loan portfolio begins when a loan officer initially assigns each loan a risk rating, using established credit criteria. Approximately 50% of the outstanding loans and commitments are subject to review and validation annually by an independent consulting firm, as well as periodically by the Company's internal credit review function. The methodology employs Management's judgment as to the level of losses on existing loans based on internal review of the loan portfolio, including an analysis of a borrower's current financial position, and the consideration of current and anticipated economic conditions and their potential effects on specific borrowers and or lines of business. In determining the Company's ability to collect certain loans, Management also considers the fair value of underlying collateral. The risk rating system has eight levels, defined as follows: 1 Strong Credits rated "1" are characterized by borrowers fully responsible for the credit with excellent capacity to pay principal and interest. Loans rated "1" may be secured with acceptable forms of liquid collateral. 2 Above Average Credits rated "2" are characterized by borrowers that have better than average liquidity, capitalization, earnings and/or cash flow with a consistent record of solid financial performance. 3 Satisfactory Credits rated "3" are characterized by borrowers with favorable liquidity, profitability and financial condition with adequate cash flow to pay debt service. 4 Average Credits rated "4" are characterized by borrowers that present risk more than 1, 2 and 3 rated loans and merit an ordinary level of ongoing monitoring. Financial condition is on par or somewhat below industry averages while cash flow is generally adequate to meet debt service requirements. 5 Watch Credits rated "5" are characterized by borrowers that warrant greater monitoring due to financial condition or unresolved and identified risk factors. 6 Other Assets Especially Mentioned (OAEM) Loans in this category are currently protected but are potentially weak and constitute an undue and unwarranted credit risk, but not to the point of justifying a classification of substandard. OAEM have potential weaknesses which may, if not checked or corrected, weaken the asset or inadequately protect the Bank's credit position at some future date. 7 Substandard Loans in this category are inadequately protected by the current sound worth and paying capacity of the borrower or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Substandard loans are characterized by the distinct possibility that the Bank may sustain some loss if the deficiencies are not corrected. 8 Doubtful Loans classified "Doubtful" have the same weaknesses as those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, based on currently existing facts, conditions, and values, highly questionable and improbable. The possibility of loss is high, but because of certain important and reasonably specific pending factors which may work to the advantage and strengthening of the asset, its classification as an estimated loss is deferred until its more exact status may be determined.

Commercial loans are generally charged off when all or a portion of the principal amount is determined to be uncollectible. This determination is based on circumstances specific to a borrower including repayment ability, analysis of collateral and other factors as applicable. Residential loans are comprised of two classes: term loans, which include traditional amortizing home mortgages, and construction loans, which include loans for owner-occupied residential construction. Residential loans typically have a 75% to 80% loan to value based upon current appraisal information at the time the loan is made. Home equity loans and lines of credit are typically written to the same underwriting standards. Consumer loans are primarily amortizing loans to individuals collateralized by automobiles, pleasure craft and recreation vehicles, typically with a maximum loan to value of 80% to 90% of the purchase price of the collateral. Consumer loans also include a small amount of unsecured short-term time notes to individuals. Residential loans, consumer loans and home equity lines of credit are segregated into homogeneous pools with similar risk characteristics. Trends and current conditions are analyzed and historical loss experience is adjusted accordingly. Quantitative and qualitative adjustment factors for these segments are consistent with those for the commercial and municipal classes. Certain loans in the residential, home equity lines of credit and consumer classes identified as having the potential for further deterioration are analyzed individually to confirm impairment status, and to determine the need for a specific reserve; however there is no formal rating system used for these classes. Consumer loans greater than 120 days past due are generally charged off. Residential loans 90 days or more past due are placed on non-accrual status unless the loans are both well secured and in the process of collection. One- to four-family residential real estate loans and home equity loans are written down or charged-off no later than 180 days past due, or for residential real estate secured loans having a borrower in bankruptcy, within 60 days of receipt of notification of filing from the bankruptcy court, whichever is sooner. This is subject to completion of a current assessment of the value of the collateral with any outstanding loan balance in excess of the fair value of the property, less costs to sell, written down or charged-off.

Troubled Debt Restructured A troubled debt restructured ("TDR") constitutes a restructuring of debt if the Company, for economic or legal reasons related to the borrower's financial difficulties, grants a concession to the borrower that it would not otherwise consider. To determine whether or not a loan should be classified as a TDR, Management evaluates a loan based upon the following criteria:
• | The borrower demonstrates financial difficulty; common indicators include past due status with bank obligations, substandard credit bureau reports, or an inability to refinance with another lender, and
• | The Company has granted a concession; common concession types include maturity date extension, interest rate adjustments to below market pricing, and deferment of payments.
As of March 31, 2013, the Company had 106 loans with a value of $31,147,000 that have been classified as TDRs. This compares to 101 loans with a value of $29,955,000 and 71 loans with a value of $20,647,000 classified as TDRs as of December 31, 2012 and March 31, 2012, respectively. The impairment carried as a specific reserve in the allowance for loan losses is calculated by present valuing the cashflow modification on the loan, or, for collateral-dependent loans, using the fair value of the collateral less costs to sell. The following table shows TDRs by class and the specific reserve as of March 31, 2013:
