The Company closely monitors economic conditions and loan performance trends to manage and evaluate the exposure to credit risk. Key factors tracked by the Company and utilized in evaluating the credit quality of the loan portfolio include trends in delinquency ratios, the level of nonperforming assets, borrower’s repayment capacity, and collateral coverage.

Assets are graded “pass” when the relationship exhibits acceptable credit risk and indicates repayment ability, tolerable collateral coverage and reasonable performance history. Lending relationships exhibiting potentially significant credit risk and marginal repayment ability and/or asset protection are graded “special mention.” Assets 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 must have a well-defined weakness that jeopardizes the liquidation of the debt. Substandard graded loans are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Assets graded “doubtful” are substandard graded loans that have added characteristics that make collection or liquidation in full improbable. The Company typically measures impairment based on the present value of expected future cash flows, discounted at the loan's effective interest rate, or based on the loan's observable market price or the fair value of the collateral if the loan is collateral-dependent.

The following tables summarize the credit exposure in the Company’s consumer and commercial loan portfolios as of:

A troubled debt restructuring (“TDR”) is a restructuring in which a bank, for economic or legal reasons related to a borrower's financial difficulties, grants a concession to the borrower that it would not otherwise consider. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due from the borrower in accordance with original contractual terms of the loan. Loans with insignificant delays or insignificant short falls in the amount of payments expected to be collected are not considered to be impaired. Loans defined as individually impaired, based on applicable accounting guidance, include larger balance nonperforming loans and TDRs.

The following tables present loans by class, modified as TDRs, that occurred during the six months ended June 30, 2019, the twelve months ended December 31, 2018 and the six months ended June 30, 2018:

There was one TDR that subsequently defaulted, therefore remained on nonaccrual status as of December 31, 2018. The TDRs described above did not increase the allowance for loan losses and resulted in no charge-offs during the year ended December 31, 2018.

There were no TDRs that subsequently defaulted through June 30, 2018. The TDRs described above did not increase the allowance for loan losses and resulted in no charge-offs during the six months ended June 30, 2018.
