Loan Portfolio Credit Quality Internal Grading System Policy	The Company reviews the credit quality of its loan portfolio using an internal grading system that classifies loans as “Satisfactory,” “Watch,” “Special Mention,” “Substandard” and “Doubtful.” Loans classified as watch are being monitored because of indications of potential weaknesses or deficiencies that may require future classification as special mention or substandard. Special mention loans possess potential weaknesses that deserve management’s close attention but do not expose the Bank to a degree of risk that warrants substandard classification. Substandard loans are characterized by the distinct possibility that the Bank will sustain some loss if certain deficiencies are not corrected. Doubtful loans are those having all the weaknesses inherent to those classified Substandard with the added characteristics 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 any of the criteria previously described are considered satisfactory. The FDIC-assisted acquired loans are evaluated using this internal grading system. These loans are accounted for in pools. Minimal adverse classification in these acquired loan pools was identified as of December 31, 2017 and 2016, respectively. See Note 4 for further discussion of the acquired loan pools and termination of the loss sharing agreements. The Company evaluates the loan risk internal grading system definitions and allowance for loan loss methodology on an ongoing basis. The general component of the allowance for loan losses is affected by several factors, including, but not limited to, average historical losses, average life of the loans, the current composition of the loan portfolio, current and expected economic conditions, collateral values and internal risk ratings. Management considers all these factors in determining the adequacy of the Company’s allowance for loan losses. No significant changes were made to the loan risk grading system definitions and allowance for loan loss methodology during the past year.
