[1] | At the end of each quarter, Pinnacle Financial evaluates the inherent risks of the outstanding off-balance sheet commitments. In making this evaluation, Pinnacle Financial evaluates the credit worthiness of the borrower, the collateral supporting the commitments and any other factors similar to those used to evaluate the inherent risks of our loan portfolio. Additionally, Pinnacle Financial evaluates the probability that the outstanding commitment will eventually become a funded loan. As a result, at March 31, 2018 and December 31, 2017, Pinnacle Financial included in other liabilities $1.9 million and $2.3 million, respectively, representing the inherent risks associated with these off-balance sheet commitments.
[2] | At March 31, 2018 and December 31, 2017, the aggregate fair value of Pinnacle Financial's standby letters of credit was $1.1 million and $800,000, respectively. These amounts represent the unamortized fee associated with these standby letters of credit and are included in the consolidated balance sheets of Pinnacle Financial and are believed to approximate fair value. These fair values will decrease over time as the existing standby letters of credit approach their expiration dates.
[3] | Estimated fair values are consistent with an exit-price concept. The assumptions used to estimate the fair values are intended to approximate those that a market-participant would realize in a hypothetical orderly transaction.
