These amendments allow an entity to make a reclassification from other comprehensive income to retained earnings for the difference between the historical corporate income tax rate and the newly enacted corporate income tax rate. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those years. Early adoption is permitted with retrospective application. This standard will not have a material impact on Pinnacle Financial's consolidated financial statements.</font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In January 2017, the FASB issued </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Accounting Standards Update No. 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment</font><font style="font-family:inherit;font-size:10pt;"> to simplify how entities other than private companies, such as public business entities and not-for-profit entities, are required to test goodwill for impairment by eliminating the comparison of the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill. The amendments are effective for fiscal years beginning after December 15, 2019, including interim periods within those periods. 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. </font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In February 2016, the FASB issued </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Accounting Standards Update 2016-02, Leases</font><font style="font-family:inherit;font-size:10pt;"> which requires recognition in the statement of financial position of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. The guidance requires that a lessee should recognize lease assets and lease liabilities as compared to previous GAAP that did not require lease assets and lease liabilities to be recognized for operating leases. The guidance becomes effective for Pinnacle Financial on January 1, 2019.  In July 2016, the FASB issued </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Accounting Standards Update 2018-10, Codification Improvements to Topic 842, Leases</font><font style="font-family:inherit;font-size:10pt;"> which provides technical corrections and improvements to ASU 2016-02. It is not anticipated that this update will have an impact on our adoption of ASU 2016-02. In July 2016, the FASB issued </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Accounting Standards Update 2018-11, Leases (Topic 842): Targeted Improvements</font><font style="font-family:inherit;font-size:10pt;"> which provides an optional transition method to adopt the new requirements of ASU 2016-02 as of the adoption date with no adjustment to the presentation or disclosure of comparative prior periods included in the financial statements in the period of adoption. Pinnacle Financial intends to elect the optional transition method which will result in presentation of periods prior to adoption under the prior lease guidance of ASC Topic 840. In December 2018, the FASB issued </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Accounting Standards Update 2018-20, Leases (Topic 842): Narrow-Scope Improvements for Lessors</font><font style="font-family:inherit;font-size:10pt;">. ASU 2018-20 permits lessors to account for certain taxes as lessee costs, permits lessors to exclude from revenue certain lessor costs paid by lessees directly to third parties, and requires lessors to allocate certain variable payments to lease and non-lease components. Had these standards been effective as of December 31, 2018, we would have recorded a right of use asset and additional lease liabilities of approximately $</font><font style="font-family:inherit;font-size:10pt;">80</font><font style="font-family:inherit;font-size:10pt;"> million.</font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In June 2016, the FASB issued </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Accounting Standards Update 2016-13</font><font style="font-family:inherit;font-size:10pt;">,  </font><font style="font-family:inherit;font-size:10pt;font-style:italic;">Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments </font><font style="font-family:inherit;font-size:10pt;">(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 new model will require institutions to calculate all probable and estimable losses that are expected to be incurred through the financial asset's entire 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. The amendments are effective for fiscal years beginning after December 15, 2019. Early application will be permitted for fiscal years beginning after December 15, 2018. Pinnacle Financial is currently assessing the impact of the new guidance on its consolidated financial statements. An increase in the overall allowance for loan losses is likely upon adoption in order to provide for expected credit losses over the life of the loan portfolio.</font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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.</font></div></div>

Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term include the determination of the allowance for loan losses, determination of any impairment of goodwill or intangible assets and the valuation of deferred tax assets.</font></div></div>
