In determining the adequacy of the allowance for loan loss, general allocations are made for other pools of loans, including non-classified loans, homogeneous portfolios of consumer and residential real estate loans, and loans within certain industry categories believed to present unique risk of loss. General allocations of the allowance are primarily made based on historical averages for loan losses for these portfolios, judgmentally adjusted for current economic factors and portfolio trends.

Loan impairment is reported when full repayment under the terms of the loan is not expected. This methodology is used for all loans, including loans acquired with deteriorated credit quality. For purchased loans, the assessment is made at the time of acquisition as well as over the life of loan. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported net, at the present value of estimated future cash flows using the loan’s existing rate, or at the fair value of collateral if repayment is expected solely from the collateral. Commercial and industrial loans, commercial real estate loans, and agricultural loans are evaluated individually for impairment. Smaller balance homogeneous loans are evaluated for impairment in total. Such loans include real estate loans secured by one-to-four family residences and loans to individuals for household, family and other personal expenditures. Individually evaluated loans on non-accrual are generally considered impaired. Impaired loans, or portions thereof, are charged off when deemed uncollectible.

All classes of loans, including loans acquired with deteriorated credit quality, are generally placed on non-accrual status when scheduled principal or interest payments are past due for 90 days or more or when the borrower’s ability to repay becomes doubtful. For purchased loans, the determination is made at the time of acquisition as well as over the life of the loan. Uncollected accrued interest for each class of loans is reversed against income at the time a loan is placed on non-accrual. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. All classes of loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Loans are typically charged-off at 180 days past due, or earlier if deemed uncollectible. Exceptions to the non-accrual and charge-off policies are made when the loan is well secured and in the process of collection.
 
The following tables present the recorded investment in non-accrual loans and loans past due 90 days or more still on accrual by class of loans as of December 31, 2015 and 2014:

Troubled Debt Restructurings:
 
In certain instances, the Company may choose to restructure the contractual terms of loans. A troubled debt restructuring occurs when the Bank grants a concession to the borrower that it would not otherwise consider due to a borrower’s financial difficulty. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without modification. This evaluation is performed under the Company’s internal underwriting policy. The Company uses the same methodology for loans acquired with deteriorated credit quality as for all other loans when determining whether the loan is a troubled debt restructuring.
 
During the year ended December 31, 2015, there were no new troubled debt restructurings. During the year ended December 31, 2014, there was one loan modified as troubled debt restructuring. The modification of the terms of this loan included a permanent reduction of the recorded investment in the loan.

Credit Quality Indicators:
 
The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company classifies loans as to credit risk by individually analyzing loans. This analysis includes commercial and industrial loans, commercial real estate loans, and agricultural loans with an outstanding balance greater than $100. This analysis is typically performed on at least an annual basis. The Company uses the following definitions for risk ratings:
 
Special Mention. Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date.
 
Substandard. Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.
 
Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.
 
Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans. Based on the most recent analysis performed, the risk category of loans by class of loans is as follows:

Mention
