[1] Approximately $16.7 million and $19.0 million of nonaccrual loans as of December 31, 2016 and 2015, respectively, are currently performing pursuant to their contractual terms.

[2] Potential problem loans represent those loans with a well-defined weakness and where information about possible credit problems of borrowers has caused management to have doubts about the borrower's ability to comply with present repayment terms. This definition is believed to be substantially consistent with the standards established by Pinnacle Bank's primary regulators for loans classified as substandard, excluding the impact of substandard nonperforming loans and substandard troubled debt restructurings. Potential problem loans, which are not included in nonperforming assets, amounted to approximately $114.6 million at December 31, 2016 compared to $105.0 million at December 31, 2015.

[3] Included in nonaccrual loans at December 31, 2016 and 2015 are $8.8 million and $12.1 million, respectively, in loans acquired with deteriorated credit quality and accounted for as purchase credit impaired.

[4] Troubled debt restructurings are presented as an impaired loan; however, they continue to accrue interest at contractual rates.

[5] All of the acquired impaired loans have been deemed to be collateral dependent and as such were placed on nonaccrual. As such, no accretable difference has been recorded on these loans.
