This standard became effective for Pinnacle Financial on January 1, 2020. If this standard had been effective as of the date of the financial statements included in this report, there would have been no impact on Pinnacle Financial's consolidated financial statements.</span></div><div style="text-indent:18pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">In June 2016, the FASB issued </span><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%;">Accounting Standards Update 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments</span><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;"> (CECL), which introduces the current expected credit losses methodology. Among other things, CECL requires the measurement of all expected credit losses for financial assets, including loans and held-to-maturity debt securities, held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The standard requires institutions to calculate all probable and estimable losses that are expected to be incurred through the financial asset's entire contractual life through a provision for credit losses, including loans obtained as a result of any acquisition not deemed to be purchased credit deteriorated (PCD). CECL also requires the allowance for credit losses for PCD loans to be determined in a manner similar to that of other financial assets measured at amortized cost; however, the initial allowance will be added to the purchase price rather than recorded as provision expense. The disclosure of credit quality indicators related to the amortized cost of financing receivables will be further disaggregated by year of origination (or vintage). Institutions are to apply the changes through a cumulative-effect adjustment to their retained earnings as of the beginning of the first reporting period in which the standard is effective. This standard became effective for Pinnacle Financial on January 1, 2020.</span></div><div style="text-indent:18pt;"><span><br/></span></div><div style="text-indent:18pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">Pinnacle Financial has established a cross-functional CECL Steering Committee, which includes members from the accounting, treasury, credit and lending functions, with involvement from members of model risk management, independent loan review and internal audit. Pinnacle Financial leveraged both internal and external expertise in the development of the models that will be utilized in the determination of the allowance for credit losses pursuant to CECL. At this time, Pinnacle Financial is focused on refining economic forecasts and certain other key assumptions utilized in our model, finalizing model validations and internal controls, and the creation of the financial statement disclosures. Pinnacle Financial has concluded that the overall allowance for credit losses will increase upon adoption of CECL in order to provide for expected credit losses over the life of the loan portfolio. Pinnacle Financial expects the allowance for credit losses to increase from 0.48% as a percentage of total loans at December 31, 2019 to a range between 0.65% and 0.70% of total loans upon adoption of this standard, primarily resulting from the impact of adjusting from the incurred loss model to the expected loss model. The allowance for credit losses also increased due to the requirement to record an allowance on acquired loan portfolios, previously recorded at fair value. Once finalized, the cumulative effect adjustment, as a result of the adoption of this guidance, will be recorded, net of tax, as an adjustment to retained earnings effective January 1, 2020. This estimate is subject to change as key assumptions are refined and model validations are finalized.</span></div><div style="text-indent:18pt;"><span><br/></span></div><div style="text-indent:18pt;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;">Other than those pronouncements discussed above and those which have been recently adopted, we do not believe there were any other recently issued accounting pronouncements that are expected to materially impact Pinnacle Financial.</span></div>
