NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

Note 1. Summary of Significant Accounting Policies

Nature of Business — Pinnacle Financial Partners, Inc. (Pinnacle Financial) is a bank holding company whose primary business is conducted by its wholly-owned subsidiary, Pinnacle Bank. Pinnacle Bank is a commercial bank headquartered in Nashville, Tennessee. Pinnacle Financial completed its acquisitions of CapitalMark Bank & Trust (CapitalMark), Magna Bank (Magna), Avenue Financial Holdings, Inc. (Avenue) and BNC Bancorp (BNC) on July 31, 2015, September 1, 2015, July 1, 2016 and June 16, 2017, respectively. Pinnacle Financial and Pinnacle Bank also collectively hold a 49% interest in Bankers Healthcare Group, LLC (BHG), a full-service commercial loan provider to healthcare and other professional practices. Pinnacle Bank provides a full range of banking services, including investment, mortgage, insurance, services, and comprehensive wealth management services, in its 11 primarily urban markets within Tennessee, the Carolinas and Virginia. In addition to the offices in those primary markets, Pinnacle Financial has recently opened loan production offices in Indiana and Texas.

Basis of Presentation — The accompanying unaudited consolidated financial statements have been prepared in accordance with instructions to Form 10-Q and therefore do not include all information and footnotes necessary for a fair presentation of financial position, results of operations, and cash flows in conformity with U.S. generally accepted accounting principles (U.S. GAAP).  All adjustments consisting of normally recurring accruals that, in the opinion of management, are necessary for a fair presentation of the financial position and results of operations for the periods covered by the report have been included. The accompanying unaudited consolidated financial statements should be read in conjunction with the Pinnacle Financial consolidated financial statements and related notes appearing in Pinnacle Financial's Annual Report on Form 10-K for the year ended December 31, 2016 (20162017 (2017 10-K).

These consolidated financial statements include the accounts of Pinnacle Financial and its wholly-owned subsidiaries. Certain statutory trust affiliates of Pinnacle Financial, as noted in Note 12. Subordinated Debt and Other Borrowings are included in these consolidated financial statements pursuant to the equity method of accounting. Significant intercompany transactions and accounts are eliminated in consolidation.

Use of Estimates — The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the balance sheet date and the reported amounts of revenues and expenses during the reporting period. 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 intangible assets and the valuation of deferred tax assets. Certain refinements to the determination of the allowance for loan losses were made during the quarter ended September 30, 2017 and are discussed more fully below. Additionally, the adoption of ASU 2016-09, which became effective January 1, 2017, and is described more fully in Recently Adopted Accounting Pronouncements below is representative of a change in estimate. Other than the items noted herein, thereThere have been no significant changes to Pinnacle Financial's significant accounting policies as disclosed in the 20162017 10-K.

Allowance for Loan Losses (allowance) -  Pinnacle Financial's management assesses the adequacy of the allowance prior to the end of each calendar quarter. This assessment includes procedures to estimate the allowance and test the adequacy and appropriateness of the resulting balance. The level of the allowance is based upon management's evaluation of the loan portfolio, loan loss experience, asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect the borrowers' ability to repay the loan (including the timing of future payment), the estimated value of any underlying collateral, composition of the loan portfolio, economic conditions, industry and peer bank loan quality indications and other pertinent factors, including regulatory recommendations.  The level of allowance maintained by management is believed adequate to absorb probable losses inherent in the loan portfolio at the balance sheet date. The allowance is increased by provisions charged to expense and decreased by charge-offs, net of recoveries of amounts previously charged-off.  Allocation of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management's judgment, is deemed uncollectible.

Pinnacle Financial's allowance for loan loss assessment methodology was modified in the quarter ended September 30, 2017 to (i) extend the lookback period from 24 quarters to a period beginning January 1, 2006 to better capture a complete economic cycle, (ii) eliminate the use of risk ratings in the calculation of the loss rate and instead focus on risk by loan type and (iii) expand the economic variables used in the qualitative assessment to incorporate our expanded footprint. Pinnacle Financial also eliminated the use of a loss emergence period in light of the minimal population of losses available to evaluate that were previously being extrapolated to the full population of loans, and shifted the focus of its analysis to more of a quantitative model. There was no material impact on the adoption of the change in the allowance for loan loss assessment methodology.


Pinnacle Financial's allowance for loan losses is composed of the result of two independent analyses pursuant to the provisions of ASC 450-20, Loss Contingencies and ASC 310-10-35, Receivables. The ASC 450-20 analysis is intended to quantify the inherent risks in its performing loan portfolio. The ASC 310-10-35 analysis includes a loan-by-loan analysis of impaired loans, both those reported as nonaccrual and troubled-debt restructurings.
In assessing the adequacy of the allowance, Pinnacle Financial also considers the results of Pinnacle Financial's ongoing independent loan review process. Pinnacle Financial undertakes this process both to ascertain those loans in the portfolio with elevated credit risk and to assist in its overall evaluation of the risk characteristics of the entire loan portfolio.  Its loan review process includes the judgment of management, independent internal loan reviewers, and reviews that may have been conducted by third-party reviewers including regulatory examiners. Pinnacle Financial incorporates relevant loan review results in the allowance.
The ASC 450-20 component of the allowance for loan losses begins with a historical loss rate calculation for each loan pool with similar risk characteristics. The losses realized over a rolling four-quarter cycle are utilized to determine an annual loss rate for each loan pool for each quarter-end in our look-back period. The look-back period in our loss rate calculation begins with January 2006, as we believe the period from January 1, 2006 to September 30, 2017 is more representative of a complete economic cycle. The loss rates for each category are then averaged and applied to the end of period loan portfolio balances to determine estimated losses. The loss rates provide a quantitative estimate of credit losses inherent in our end of period loan portfolio based on our actual loss experience.

The estimated loan loss allocation for all loan segments is then adjusted for management's estimate of probable losses for a number of qualitative factors that have not been considered in the quantitative analysis. The qualitative categories and the measurements used to quantify the risks within each of these categories are subjectively selected by management, but measured by objective measurements period over period.  The data for each measurement may be obtained from internal or external sources.  The current period measurements are evaluated and assigned a factor commensurate with the current level of risk relative to past measurements over time. The resulting factor is applied to the non-impaired loan portfolio.  This amount represents estimated probable inherent credit losses which exist, but have not yet been identified either in its risk rating or impairment process, as of the balance sheet date, and is based upon quarterly trend assessments in portfolio concentrations, policy exceptions, economic conditions, associate retention, independent loan review results, collateral considerations, credit quality, competition and regulatory requirements, enterprise wide risk assessments, and peer group credit quality.  The qualitative allowance allocation, as determined by the processes noted above, is increased or decreased for each loan segment based on the assessment of these various qualitative factors.
The allowance for loan losses for purchased loans is calculated similar to that utilized for legacy Pinnacle Bank loans. Pinnacle Financial's accounting policy is to compare the computed allowance for loan losses for each purchased loan to the remaining fair value adjustment at the individual loan level. If the computed allowance at the loan level is greater than the remaining fair value adjustment, the excess is added to the allowance for loan losses by a charge to the provision for loan losses.
The ASC 450-20 portion of the allowance includes a small unallocated component.  Pinnacle Financial believes that the unallocated amount is warranted for inherent factors that cannot be practically assigned to individual loan categories, such as the imprecision in the overall loss allocation measurement process, the subjectivity risk of potentially not considering all relevant environmental categories and related measurements and imprecision in its credit risk ratings process. The appropriateness of the unallocated component of the allowance is assessed each quarter end based upon changes in the overall business environment not otherwise captured.
The impaired loan allowance is determined pursuant to ASC 310-10-35.  Loans are impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement. Collection of all amounts due according to the contractual terms means collecting all interest and principal payments of a loan as scheduled in the loan agreement.  This evaluation is inherently subjective as it requires material estimates including the amounts and timing of future cash flows expected to be received on impaired loans that may be susceptible to significant change. Loan losses are charged off when management believes that the full collectability of the loan is unlikely.  A loan may be partially charged-off after a "confirming event" has occurred which serves to validate that full repayment pursuant to the terms of the loan is unlikely.
An impairment allowance is recognized if the fair value of the loan is less than the recorded investment in the loan (recorded investment in the loan is the principal balance plus any accrued interest, net of deferred loan fees or costs and unamortized premium or discount). The impairment is recognized through the provision for loan losses and is a component of the allowance for loan losses. Loans that are impaired are recorded at the present value of expected future cash flows discounted at the loan's effective interest rate, or if the loan is collateral dependent, at the fair value of the collateral, less estimated disposal costs. If the loan is cash flow dependent, a specific reserve is established as a component of the allowance. If the loan is collateral dependent, the principal balance of the loan is charged-off in an amount equal to the impairment measurement. The fair value of collateral dependent loans is derived primarily

from collateral appraisals performed by independent third-party appraisers.  Management believes it follows appropriate accounting and regulatory guidance in determining impairment and accrual status of impaired loans. This analysis is completed for all individual loans greater than $250,000. The resulting allowance percentage by segment adjusted for specific trends identified, if applicable, is then applied to the remaining population of impaired loans.
Pursuant to the guidance set forth in ASU No. 2011-02, A Creditor's Determination of Whether a Restructuring is a Troubled Debt Restructuring, the above impairment methodology is also applied to those loans identified as troubled debt restructurings.
Sufficiency of the computed allowance is then tested by comparison to historical trends and industry and peer information. Pinnacle Financial then evaluates the result of the procedures performed, including the results of our testing, and concludes on the appropriateness of the balance of the allowance in its entirety. The audit committee of the board of directors reviews and approves the methodology and resultant allowance prior to the filing of quarterly and annual financial information.

While its policies and procedures used to estimate the allowance for loan losses, as well as the resultant provision for loan losses charged to income, are considered adequate by management and are reviewed from time to time by regulators, they are necessarily approximate and imprecise. There are factors beyond its control, such as conditions in the local, national, and international economy, a local real estate market or particular industry conditions which may negatively impact materially asset quality and the adequacy of the allowance for loan losses and thus the resulting provision for loan losses.

Income Per Common Share — Basic net income per common share (EPS) is computed by dividing net income by the weighted average common shares outstanding for the period. Diluted EPS reflects the dilution that could occur if securities or other contracts to issue common stock were exercised or converted. The difference between basic and diluted weighted average shares outstanding is attributable to common stock options, common stock appreciation rights, restricted share awards, and restricted share unit awards. The dilutive effect of outstanding options, common stock appreciation rights, restricted share awards, and restricted share unit awards is reflected in diluted EPS by application of the treasury stock method.


The following is a summary of the basic and diluted net income per share calculations for the three and nine months ended September 30,March 31, 2018 and 2017 and 2016:

Recently Adopted Accounting Pronouncements    In August 2017, the FASB issued Accounting Standards Update No. 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities. The amendments in this ASU make more financial and non-financial hedging strategies eligible for hedge accounting. It also amends the presentation and disclosure requirements and changes how companies assess effectiveness. The amendments will be effective for public companies for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. Pinnacle Financial early adopted this standard in early 2018 and subsequently entered into two derivative contracts under this standard, as noted in Note 9. Derivative Instruments.

In March 2017, the FASB issued Accounting Standards Update No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendment in this ASU shortens the amortization period for certain callable debt securities held at a premium to the earliest call date. The amendment does not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those periods. Early adoption is permitted with modified retrospective application. Pinnacle Financial elected to early adopt this standard in the first quarter of 2018 with no material impact to its financial statements.

In August 2016, the FASB issued  updated guidance to Accounting Standards Update 2016-09 Stock Compensation Improvements to Employee Share-Based Payment Activity2016-15,Statement of Cash Flows (Topic 230) (ASU 2016-09) intended to simplify and improve several aspects ofreduce the accounting for share-based paymentdiversity in practice around how certain transactions including the income tax consequences, classification of such awards as either equity or liabilities and classification of such awards onare classified within the statement of cash flows. This The guidance is effective for public companies for annual periods beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted with retrospective application. Pinnacle Financial adopted this standard in the first quarter of 2018 with no material impact to its financial statements, with the exception of dividends received from our equity method investments which were reclassified from cash flow from investments to operating cash flow.

In January 2016, the FASB issued Accounting Standards Update (ASU) impacted Pinnacle Financial's consolidated financial statements2016-01 Financial Instruments – Overall (Subtopic 825-10) which, among other things, (i) requires equity investments, excluding those accounted for under the equity method or that result in consolidation, to be measured at fair value with changes in fair value recognized in net income, (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that allis required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (iv) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (v) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial

Previously, income tax benefits at settlement of an award were reported as an increase (or decrease) to additional paid-in capital. Theassets. ASU also requires that all income tax related cash flows resulting from share-based payments be reported as operating activities in the statement of cash flows whereas these cash flows were previously reported as a reduction to operating cash flows and an increase to financing cash flows. The guidance2016-01 became effective for Pinnacle Financial in the first quarter of 2018 and did not have a material impact on January 1, 2017. Duringour financial statements. See Note 10. Fair Value of Financial Instruments for disclosure of the threefair value of financial instruments based on an exit price notion as required by ASU 2016-01.

In May 2014, the FASB issued Accounting Standards Update 2014-09,Revenue from Contracts with Customers(Topic 606) developed as a joint project with the International Accounting Standards Board to remove inconsistencies in revenue requirements and nine months ended September 30, 2017,provide a more robust framework for addressing revenue issues. The ASU's core principle is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the newlyconsideration to which an entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued  Accounting Standards Update 2015-14, which deferred the effective date by one year (i.e., interim and annual reporting periods beginning after December 15, 2017). Early adoption is permitted, but not before the original effective date (i.e., interim and annual reporting periods beginning after December 15, 2016). The ASU may be adopted using either a modified retrospective method or a full retrospective method. Pinnacle Financial adopted the ASU during the first quarter of 2018, as required, using a modified retrospective approach. The majority of Pinnacle Financial's revenue stream is generated from interest income on loans and deposits, which are outside the scope of Topic 606. Pinnacle Financial’s sources of income that fall within the scope of Topic 606 include service charges on deposits, investment services, insurance sales commissions, trust fees, interchange fees and gains and losses on sales of other real estate, all of which are presented within noninterest income. Pinnacle Financial has evaluated the effect of Topic 606 on these fee-based income streams and concluded that adoption of the standard resulteddid not materially impact its financial statements. The following is a summary of the implementation considerations for the revenue streams that fall within the scope of Topic 606:

Service charges on deposits, investment services, trust fees and interchange fees — Fees from these services are either transaction based, for which the performance obligations are satisfied when the individual transaction is processed, or set periodic service charges, for which the performance obligations are satisfied over the period the service is provided. Transaction based fees are recognized at the time the transaction is processed, and periodic service charges are recognized over the service period. The adoption of Topic 606 had no impact on Pinnacle Financial's revenue recognition practice for these services.

Insurance sales commissions — Insurance commissions are received from insurance companies in return for the placement of policies with customers. While additional services, such as claims assistance, may be provided over the term of the policy, the revenues are substantially earned at the time of policy placement. The only contingency in earning the revenue relates to the potential for subsequent cancellation of policies. Accordingly, revenue is recognized at the time of policy placement, net of an allowance for estimated policy cancellations. The adoption of Topic 606 had no impact on Pinnacle Financial's revenue recognition related to insurance sales commissions.

Gains on sales of other real estate — ASU 2014-09 creates Topic 610-20, under which a reductiongain on sale should be recognized when a contract for sale exists and control of the asset has been transferred to the buyer. Topic 606 list several criteria which must exist to conclude that a contract for sale exists, including a determination that the institution will collect substantially all of the consideration to which it is entitled. This presents a key difference between the current and new guidance related to the recognition of the gain when the institution finances the sale of the property. Rather than basing recognition on the amount of the buyer's initial investment, which was the primary consideration under prior guidance, the analysis is now based on various factors including not only the loan to value, but also the credit quality of the borrower, the structure of the loan, and any other factors that may affect collectability. While these differences may affect the decision to recognize or defer gains on sales of other real estate in tax expense of $59,000 and $4.6 million, respectively.circumstances where Pinnacle Financial has financed the sale, the effects would not be material to its financial statements.

Subsequent Events  Accounting Standards Codification (ASC) Topic 855, Subsequent Events, establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued. Pinnacle Financial evaluated all events or transactions that occurred after September 30, 2017March 31, 2018 through the date of the issued financial statements. Following early adoption of ASU 2017-12 as noted above, Pinnacle Financial entered into a derivative transaction on April 10, 2018 that has been more fully disclosed in Note 9. Derivative Instruments. Other than the above-noted transaction, no other subsequent events were noted.

On April 17, 2018, Pinnacle Financial's shareholders approved an amendment to Pinnacle Financial's Charter to increase the number of authorized shares of capital stock from 100,000,000 to 190,000,000 shares, in both instances 10,000,000 of which are reserved for issuance as preferred stock.


Note 2. Acquisitions
 
BNC Bancorp. On June 16, 2017, Pinnacle Financial consummated its merger with BNC. Pursuant to the terms of the Agreement and Plan of Merger, dated as of January 22, 2017, by and between Pinnacle Financial and BNC, BNC merged with and into Pinnacle Financial, with Pinnacle Financial continuing as the surviving corporation (the BNC Merger). On that same day, Pinnacle Bank and Bank of North Carolina, BNC's wholly-owned bank subsidiary, merged, with Pinnacle Bank continuing as the surviving entity.

  $1,858,262
 
Subsequently, Pinnacle Financial recorded costs incurred in connection with the issuance of Pinnacle Financial common stock resulting from the BNC Merger of $10.3$7.2 million, which was recordednet of related tax benefits, as a reduction to additional paid in capital. Certain merger-related charges resulting from cultural and systems integrations, as well as stock-based compensation expense incurred as a result of change-in-control provisions applicable to assumed equity-based awards were recorded as merger-related expense.

Goodwill originating from the BNC Merger resulted primarily from anticipated synergies arising from the combination of certain operational areas of the businesses of BNC and Pinnacle Financial as well as the purchase premium inherent in buying a complete and successful banking operation. Goodwill associated with the BNC Merger is not amortizable for book or tax purposes. Adjustments totaling $1.8$83.2 million were recorded to goodwill to appropriately reflect the valuation of the loan portfolio, OREO acquired, and certain liabilities assumed and have been included in the table below.

Pinnacle Financial accounted for the BNC Merger under the acquisition method in accordance with ASC Topic 805. Accordingly, the purchase price is allocated to the fair value of the assets acquired and liabilities assumed as of the date of merger.

The following purchase price allocations on the BNC Merger are preliminary and will be finalized upon the receipt of final valuations on certain assets and liabilities. Upon receipt of final fair value estimates, which must be received within one year of the BNC Merger date, Pinnacle Financial will make any final adjustments to the purchase price allocation and prospectively adjust any goodwill recorded. Information regarding Pinnacle Financial's loan discount and related deferred tax asset, core deposit intangible asset and related deferred tax liability, as well as income taxes payable and the related deferred tax balances recorded in the BNC Merger, may be adjusted as Pinnacle Financial refines its estimates. Determining the fair value of assets and liabilities, particularly illiquid assets and liabilities, is a complicated process involving significant judgment regarding estimates and assumptions used to calculate estimated fair value. Fair value adjustments based on updated estimates could materially affect the goodwill recorded on the BNC Merger. Pinnacle Financial may incur losses on the acquired loans that are materially different from losses Pinnacle Financial originally projected.

Explanation of certain fair value adjustments:
(1)The amount represents the adjustment of the book value of BNC's assets and liabilities to their estimated fair value on the date of acquisition. Fair value adjustments are updated subsequent to the merger date based on the results of finalized valuation assessements.assessments.
(2)The amount represents the adjustment of the net book value of BNC's loans to their estimated fair value based on interest rates and expected cash flows as of the date of acquisition, which includes estimates of expected credit losses inherent in the portfolio of approximately 2.6% of the 3.1% mark on the acquired loan portfolio. The discount recorded was increased by $6.0 million during the third quarter as valuation information related to certain purchase credit impaired loans became available.
(3)Although not complete, this adjustment reflects the Day 1 value of OREO properties subsequently sold.
(4)The amount represents the fair value of the core deposit intangible asset representing the intangible value of the deposit base acquired and the fair value of the customer relationship intangible assets representing the intangible value of customer relationships acquired.
(5)AThe amount represents the adjustment of the net book value of BNC's property, plant and equipment to estimated fair value adjustment for property and equipment will be recorded, but no estimate is determinable at this time.based on market values of similar assets.
(6)The amount represents the deferred tax asset recognized on the fair value adjustment of BNC's acquired assets and assumed liabilities.
(7)The amount represents the adjustment necessary because the weighted average interest rate of BNC's deposits exceeded the cost of similar funding at the time of acquisition. The fair value adjustment will be amortized to reduce future interest expense over the life of the portfolio.
(8)The amount represents the combined adjustment necessary because the weighted average interest rate of BNC's subordinated debt issuance exceeded the cost of similar funding at the time of acquisition and because the weighted average interest rate of BNC's trust preferred securities issuances was lower than the cost of similar funding at the time of acquisition. The combined fair value adjustments will be amortized to increase future interest expense over the lives of the portfolios.instruments.
(9)The amount represents the adjustment to accrue obligations that existed but had not been recorded as of the acquisition date and the fair value of BNC lease obligations.

Supplemental Pro Forma Combined Results of Operations
The supplemental proforma information below for the three and nine months ended September 30,March 31, 2017 and 2016 gives effect to the BNC acquisition as if it had occurred on January 1, 2016.2017. These results combine the historical results of BNC into Pinnacle Financial's consolidated statement of income and, while certain adjustments were made for the estimated impact of certain fair value adjustments, they are not indicative of what would have occurred had the BNC Merger taken place on the indicated date nor are they intended to represent or be indicative of future results of operations. In particular, no adjustments have been made to eliminate the amount of BNC's provision for credit losses for the first ninethree months of 20162017 that may not have been necessary had the acquired loans been recorded at fair value as of the beginning of 2016.2017. Additionally, these financialsfinancial statements were not adjusted for non-recurring expenses, such as merger-related charges incurred by either Pinnacle Financial or BNC. Pinnacle Financial expects to achieve operating cost savings and other business synergies as a result of the acquisition which are also not reflected in the proforma amounts.

At September 30, 2017,March 31, 2018, approximately $1.19$1.4 billion of securities within Pinnacle Financial's investment portfolio were pledged to secure either public funds and other deposits or securities sold under agreements to repurchase. At September 30, 2017,March 31, 2018, repurchase agreements comprised of secured borrowings totaled $129.6$131.9 million and were secured by $129.6$131.9 million of pledged U.S. government agency securities, municipal securities, asset backed securities, and corporate debentures. As the fair value of securities pledged to secure repurchase agreements may decline, Pinnacle Financial regularly evaluates its need to pledge additional securities to remain adequately secured.

The amortized cost and fair value of debt securities as of September 30, 2017March 31, 2018 by contractual maturity are shown below. Actual maturities may differ from contractual maturities of mortgage- and asset-backed securities since the mortgages and assets underlying the securities may be called or prepaid with or without penalty. Therefore, these securities are not included in the maturity categories in the following summary (in thousands):

The applicable dates for determining when securities arewere in an unrealized loss position are September 30, 2017were March 31, 2018 and December 31, 2016.2017. As such, it is possible that a security had a market value that exceeded its amortized cost on other days during the past twelve-month periods ended September 30, 2017March 31, 2018 and December 31, 2016,2017, but is not in the "Investments with an Unrealized Loss of less than 12 months" category above.

As shown in the tables above, including both available-for-sale and held-to-maturity investment securities, at September 30, 2017,March 31, 2018, Pinnacle Financial had approximately $22.9$52.1 million in unrealized losses on $1.95$2.30 billion of securities. The unrealized losses associated with these investment securities are driven by changes in interest rates and are not due to the credit quality of the securities.  These securities will continue to be monitored as a part of Pinnacle Financial's ongoing impairment analysis. Management evaluates the financial performance of the issuers on a quarterly basis to determine if it is probable that the issuers can make all contractual principal and interest payments. Because Pinnacle Financial currently does not intend to sell those securities that have an unrealized loss at September 30, 2017,March 31, 2018, and it is not more-likely-than-not that Pinnacle Financial will be required to sell the securities before recovery of their amortized cost bases, which may be maturity, Pinnacle Financial does not consider these securities to be other-than-temporarily impaired at September 30, 2017.March 31, 2018.

Periodically, available-for-sale securities may be sold or the composition of the portfolio realigned to improve yields, quality or marketability, or to implement changes in investment or asset/liability strategy, including maintaining collateral requirements and raising funds for liquidity purposes. Additionally, if an available-for-sale security loses its investment grade or tax-exempt status, the underlying credit support is terminated or collection otherwise becomes uncertain based on factors known to management, Pinnacle Financial will consider selling the security, but will review each security on a case-by-case basis as these factors become known. Consistent with the investment policy, during the first quarter of 2018 available-for-sale securities of approximately $14.5 million were sold and net unrealized gains, net of tax, of $22,000 were reclassified from accumulated other comprehensive income into net income.

The carrying values of Pinnacle Financial's investment securities could decline in the future if the financial condition of issuers deteriorates and management determines it is probable that Pinnacle Financial will not recover the entire amortized cost bases of the securities.  As a result, there is a risk that other-than-temporary impairment charges may occur in the future. Additionally, there is a risk that other-than-temporary impairment charges may occur in the future if management's intention to hold these securities to maturity and/or recovery changes. 



Note 5. Loans and Allowance for Loan Losses

For financial reporting purposes, Pinnacle Financial classifies its loan portfolio based on the underlying collateral utilized to secure each loan. This classification is consistent with those utilized in the Quarterly Report of Condition and Income filed by Pinnacle Bank with the Federal Deposit Insurance Corporation (FDIC).

Pinnacle Financial uses five loan categories: commercial real estate mortgage, consumer real estate mortgage, construction and land development, commercial and industrial, and consumer and other.
Commercial real-estatereal estate mortgage loans. Commercial real-estatereal estate mortgage loans are categorized as such based on investor exposures where repayment is largely dependent upon the operation, refinance, or sale of the underlying real estate. Commercial real-estatereal estate mortgage also includes owner occupied commercial real estate which shares a similar risk profile to Pinnacle Financial's commercial and industrial products.
Consumer real-estatereal estate mortgage loans. Consumer real-estatereal estate mortgage consists primarily of loans secured by 1-4 residential properties, including home equity lines of credit.
Construction and land development loans. Construction and land development loans include loans where the repayment is dependent on the successful operation of the related real estate project. Construction and land development loans include 1-4 family construction projects and commercial construction endeavors such as warehouses, apartments, office and retail space and land acquisition and development.
Commercial and industrial loans. Commercial and industrial loans include loans to business enterprises issued for commercial, industrial and/or other professional purposes.
Consumer and other loans. Consumer and other loans include all loans issued to individuals not included in the consumer real-estatereal estate mortgage classification. Examples of consumer and other loans are automobile loans, credit cards and loans to finance education, among others.

Commercial loans receive risk ratings assigned by a financial advisor and approved by a senior credit officer subject to validation by Pinnacle Financial's independent loan review department.  Risk ratings are categorized as pass, special mention, substandard, substandard-nonaccrual or doubtful-nonaccrual.  Pinnacle Financial believes that its categories follow those used by Pinnacle Bank's primary regulators.  At September 30, 2017,March 31, 2018, approximately 81%81.1% of Pinnacle Financial's loan portfolio was analyzed as a commercial loan type with a specifically assigned risk rating.  Consumer loans and small business loans are generally not assigned an individual risk rating but are evaluated as either accrual or nonaccrual based on the performance of the individual loans.  However, certain consumer real-estate mortgage loans and certain consumer and other loans receive a specific risk rating due to the loan proceeds being used for commercial purposes even though the collateral may be of a consumer loan nature.
 
Risk ratings are subject to continual review by a financial advisor and a senior credit officer. At least annually, Pinnacle Financial's credit procedures require that every risk rated loan of $1.0 million or more be subject to a formal credit risk review process by the assigned financial advisor. Each loan's risk rating is also subject to review by Pinnacle Financial's independent loan review department, which reviews a substantial portion of Pinnacle Financial's risk rated portfolio annually. Included in the coverage are independent loan reviews of loans in targeted higher-risk portfolio segments such as certain commercial and industrial loans, land loans and/or loan types in certain geographies.
 
The following table presents Pinnacle Financial's loan balances by primary loan classification and the amount within each risk rating category. Pass rated loans include all credits other than those included in special mention, substandard, substandard-nonaccrual and doubtful-nonaccrual which are defined as follows:


Special mention loans have potential weaknesses that deserve management's close attention.  If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in Pinnacle Financial's credit position at some future date.
Substandard loans are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any.  Assets so classified must have a well-defined weakness or weaknesses that jeopardize collection of the debt.  Substandard loans are characterized by the distinct possibility that Pinnacle Financial could sustain some loss if the deficiencies are not corrected.
Substandard-nonaccrual loans are substandard loans that have been placed on nonaccrual status.
Doubtful-nonaccrual loans have all the characteristics of substandard-nonaccrual loans with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable.


The following table outlines the amount of each loan classification categorized into each risk rating category as of September 30, 2017March 31, 2018 and December 31, 20162017 (in thousands):

(1)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 nonaccrual loans and troubled debt restructurings. Potential problem loans, which are not included in nonaccrual loans, amounted to approximately $148.7$158.1 million at September 30, 2017,March 31, 2018, compared to $114.6$164.0 million at December 31, 2016.2017.

Certain of these loans have been deemed to be collateral dependent and as such, no accretable yield has been recorded for these loans. The carrying value is adjusted for additional draws, pursuant to contractual arrangements, offset by loan paydowns. Year-to-date settlements include both loans that were charged-off as well as loans that were paid off, typically as a result of refinancings at other institutions.
 
For the three and nine months ended September 30, 2017,March 31, 2018, the average balance of nonaccrualimpaired loans was $52.4$105.0 million and $66.9 million, respectively, compared to $31.6$41.1 million and $35.1 million, respectively, for the same periodsperiod in 2016.2017. Pinnacle Financial's policy is that the accrual of interest income will be discontinued when (1) there is a significant deterioration in the financial condition of the borrower and full repayment of principal and interest is not expected or (2) the principal or interest is more than 90 days past due, unless the loan is both well secured and in the process of collection. As such, at the date the above mentioned loans were placed on nonaccrual status, Pinnacle Financial reversed all previously accrued interest income against current year earnings. Pinnacle Financial's policy is that once a loan is placed on nonaccrual status each subsequent payment is reviewed on a case-by-case basis to determine if the payment should be applied to interest or principal pursuant to regulatory guidelines. Pinnacle Financial recognized no interest income from cash payments received on nonaccrual loans during the three months ended September 30, 2017 and $65,000 during the nine months ended September 30, 2017,March 31, 2018 compared to approximately $47,000 and $95,000, respectively,$49,000 during the three and nine months ended September 30, 2016.March 31, 2017. Had these nonaccruing loans been on accruing status, interest income would have been higher by $849,000 and $2.1$1.4 million for the three and nine months ended September 30, 2017, respectively,March 31, 2018 compared to $478,000 and $999,000$640,000 higher for the three and nine months ended September 30, 2016, respectively.March 31, 2017.

At September 30, 2017March 31, 2018 and December 31, 2016,2017, there were $15.2$6.1 million and $15.0$6.6 million, respectively, of troubled debt restructurings that were performing as of their restructure date and which were accruing interest. Troubled commercial loans are restructured by specialists within Pinnacle Bank's Special Assets Group, and all restructurings are approved by committees and credit officers separate and apart from the normal loan approval process.  These specialists are charged with reducing Pinnacle Financial's overall risk and exposure to loss in the event of a restructuring by obtaining some or all of the following:  improved documentation, additional guaranties, increase in curtailments, reduction in collateral release terms, additional collateral or other similar strategies.

The  following table outlines the amount of each loan category where troubled debt restructurings were made during the three and nine months ended September 30,March 31, 2018 and 2017 and 2016 (dollars in thousands):

During the ninethree months ended September 30,March 31, 2018 and 2017, and 2016, Pinnacle Financial did not have any troubled debt restructurings that subsequently defaulted within twelve months of the restructuring.

To monitorAt March 31, 2018 and 2017, the allowance for loan losses included no allowance and $44,000, respectively, specifically related to accruing troubled debt restructurings, which are classified as impaired loans pursuant to U.S. GAAP, but which loans continued to accrue interest at contractual rates at those dates.

In addition to the loan metrics above, Pinnacle Financial analyzes its commercial loan portfolio to determine if a concentration of credit risk exists to any industries. Pinnacle Financial utilizes broadly accepted industry classification systems in order to classify borrowers into various industry classifications.  Pinnacle Financial has a credit exposure (loans outstanding plus unfunded lines of credit) exceeding 25% of Pinnacle Bank's total risk-based capital to borrowers in the following industries at September 30, 2017March 31, 2018 with the comparative exposures for December 31, 20162017 (in thousands):

Additionally, Pinnacle Financial monitors two ratios regarding construction and commercial real estate lending as part of its concentration management processes.  Both ratios are calculated by dividing certain types of loan balances for each of the two categories by Pinnacle Bank’s total risk-based capital.   At March 31, 2018 and December 31, 2017, Pinnacle Bank’s construction and land development loans as a percentage of total risk-based capital were 96.1% and 89.4%, respectively. Non-owner occupied commercial real estate and multifamily loans (including construction and land development loans) as a percentage of total risk-based capital were 306.2% and 297.1% as of March 31, 2018 and December 31, 2017, respectively. Banking regulations have established guidelines for the construction ratio of less than 100% of total risk-based capital and for the non-owner occupied ratio of less than 300% of total risk-based capital. When a bank’s ratios are in excess of one or both of these guidelines, banking regulations generally

require an increased level of monitoring in these lending areas by bank management.  At March 31, 2018 Pinnacle Bank slightly exceeded the 300% guideline and has established what it believes to be appropriate controls to monitor Pinnacle Bank's lending in this area.

(1)Loans acquired with deteriorated credit quality are recorded at fair value at the time of acquisition. An allowance for loan losses is recorded resulting from subsequent credit deterioration.

The adequacy of the allowance for loan losses is assessed at the end of each calendar quarter. The level of the allowance is based upon evaluation of the loan portfolio, current asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect the borrowers' ability to repay (including the timing of future payment), the estimated value of any underlying collateral, composition of the loan portfolio, economic conditions, historical loss experience, industry and peer bank loan quality indications and other pertinent factors, including regulatory recommendations. The allowance for loan losses for purchased loans is calculated similarly to the method utilized for legacy Pinnacle Bank loans. Pinnacle Financial's accounting policy is to compare the computed allowance for loan losses for purchased loans on a loan-by-loan basis to any remaining fair value adjustment. If the computed allowance is greater than the remaining fair value adjustment, the excess is added to the allowance for loan losses by a charge to the provision for loan losses.

At September 30,March 31, 2018, Pinnacle Bank had granted loans and other extensions of credit amounting to approximately $24.6 million to current directors, executive officers, and their related entities, of which $14.4 million had been drawn upon. At December 31, 2017, Pinnacle Bank had granted loans and other extensions of credit amounting to approximately $26.3 million to current directors, executive officers, and their related entities, of which $16.7 million had been drawn upon. At December 31, 2016, Pinnacle Bank had granted loans and other extensions of credit amounting to approximately $22.6$26.4 million to directors, executive officers, and their related entities, of which approximately $14.8$16.1 million had been drawn upon. None of these loans to directors, executive officers, and their related entities were impaired at September 30, 2017March 31, 2018 or December 31, 2016.2017.

At September 30, 2017,March 31, 2018, Pinnacle Financial had approximately $20.4$18.6 million in commercial loans held for sale compared to $25.5 million at December 31, 2017, which included loans previously held in Pinnacle Bank's commercial loan portfolio that it has elected to sell, as well as apartment loans originated for sale to a third-party as part of a multi-family loan program. Such loans are closed under a pass-through commitment structure wherein Pinnacle Bank's loan commitment to the borrower is the same as the third party's take-out commitment to Pinnacle Bank and the third party purchase typically occurs within thirty days of Pinnacle Bank closing with the borrowers.


Residential Lending


At September 30, 2017,March 31, 2018, Pinnacle Financial had approximately $105.0$99.6 million of mortgage loans held-for-sale compared to approximately $47.7$102.7 million at December 31, 2016.2017. Total loan volumes sold during the ninethree months ended September 30, 2017March 31, 2018 were approximately $756.7$147.1 million compared to approximately $549.4$160.7 million for the ninethree months ended September 30, 2016.March 31, 2017. During the ninethree months ended September 30, 2017,March 31, 2018, Pinnacle Financial recognized $14.8$3.7 million in gains on the sale of these loans, net of commissions paid, compared to $12.9$4.2 million, net of commissions paid, during the ninethree months ended September 30, 2016.March 31, 2017.

These mortgage loans held-for-sale are originated internally and are primarily to borrowers in Pinnacle Bank's geographic markets. These sales are typically on a mandatory basis to investors that follow conventional government sponsored entities (GSE) and the Department of Housing and Urban Development/U.S. Department of Veterans Affairs (HUD/VA) guidelines.
 
Each purchaser of a mortgage loan held-for-sale has specific guidelines and criteria for sellers of loans and the risk of credit loss with regard to the principal amount of the loans sold is generally transferred to the purchasers upon sale. While the loans are sold without recourse, the purchase agreements require Pinnacle Bank to make certain representations and warranties regarding the existence and sufficiency of file documentation and the absence of fraud by borrowers or other third parties such as appraisers in connection with obtaining the loan. If it is determined that the loans sold were in breach of these representations or warranties, Pinnacle Bank has obligations to either repurchase the loan for the unpaid principal balance and related investor fees or make the purchaser whole for the economic benefits of the loan. To date, Pinnacle Bank's liability pursuant to the terms of these representations and warranties has been insignificant to Pinnacle Bank.

Note 6. Income Taxes

ASC 740, Income Taxes, defines the threshold for recognizing the benefits of tax return positions in the financial statements as "more-likely-than-not" to be sustained by the taxing authority. This section also provides guidance on the derecognition, measurement and classification of income tax uncertainties, along with any related interest and penalties, and includes guidance concerning accounting for income tax uncertainties in interim periods.
 
The unrecognized tax benefit related to uncertain tax positions related to state income tax filings was $2.8 million at March 31, 2018 compared to $1.3 million at September 30, 2017 compared to $196,000 at September 30, 2016.March 31, 2017. No change was recorded to the unrecognized tax benefit related to uncertain tax positions in each of the three and nine month periods ended September 30, 2017March 31, 2018 and 2016.2017.

Pinnacle Financial's policy is to recognize interest and/or penalties related to income tax matters in income tax expense. For the three months ended September 30, 2017March 31, 2018 there were no interest and penalties recorded in the income statement and $22,000 for the nine months ended September 30, 2017, compared to no$18,000 in interest and penalties for the three and nine months ended September 30, 2016.March 31, 2017.

Pinnacle Financial's effective tax rate for the three and nine months ended September 30, 2017March 31, 2018 was 35.2% and 31.9%, respectively,19.0% compared to 33.5% and 33.5%25.8% for the three and nine months ended September 30, 2016.March 31, 2017. The difference between the effective tax rate and the federal and state income tax statutory rate of 26.14% at March 31, 2018 and 39.23% at March 31, 2017 is primarily due to the reduction in the statutory corporate tax rate following the enactment of the Tax Cuts and Jobs Act in December 2017, state excise tax expense, investments in bank qualified municipal securities, tax benefits of Pinnacle Financial's real estate investment trust subsidiary, participation in the Tennessee Community Investment Tax Credit (CITC) program, and tax benefits associated with share-based compensation, bank-owned life insurance and our captive insurance subsidiary, offset in part by the limitation on deductibility of meals and entertainment expense and certain merger-related expenses.FDIC premiums.

Additionally, in March 2016, the FASB issued updated guidance to Accounting Standards Update, 2016-09 Stock Compensation Improvements to Employee Share-Based Payment Activity (ASU 2016-09) intended to simplify and improve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of such awards as either equity or liabilities and classification of such awards on the statement of cash flows. This Accounting Standards Update (ASU) impacted Pinnacle Financial's consolidated financial statements by requiring that all income tax effects related to settlements of share-based payment awards be reported as increases (or decreases) to income tax expense. Previously, income tax benefits at settlement of an award were reported as an increase (or decrease) to additional paid-in capital. The ASU also requires that all income tax related cash flows resulting from share-based payments be reported as operating activities in the statement of cash flows whereas these cash flows were previously reported as a reduction to operating cash flows and an increase to financing cash flows. The guidance became effective for Pinnacle Financial on January 1, 2017. The impact of the adoption of ASU 2016-09 (as described in Note 1) was included in income tax expense for the three and nine months ended September 30,March 31, 2018 and 2017 resulting in the recognition of $59,000$2.7 million and $4.6$3.8 million, respectively, of tax benefits which reduced income tax expense. Prior to the adoption of ASU 2016-09, these tax benefits were recorded as an increase to additional paid-in-capital.
 

Note 7. Commitments and Contingent Liabilities

In the normal course of business, Pinnacle Financial has entered into off-balance sheet financial instruments which include commitments to extend credit (i.e., including unfunded lines of credit) and standby letters of credit. Commitments to extend credit are usually the result of lines of credit granted to existing borrowers under agreements that the total outstanding indebtedness will not exceed a specific amount during the term of the indebtedness. Typical borrowers are commercial concerns that use lines of credit to supplement their treasury management functions, and thus their total outstanding indebtedness may fluctuate during any time period based on the seasonality of their business and the resultant timing of their cash flows.  Other typical lines of credit are related to home equity loans granted to consumers.  Commitments to extend credit generally have fixed expiration dates or other termination clauses and may require payment of a fee. At September 30, 2017,March 31, 2018, these commitments amounted to $5.2 billion.

$5.77 billion, of which approximately $917.7 million related to home equity lines of credit.

Standby letters of credit are generally issued on behalf of an applicant (our customer) to a specifically named beneficiary and are the result of a particular business arrangement that exists between the applicant and the beneficiary.  Standby letters of credit have fixed expiration dates and are usually for terms of two years or less unless terminated beforehand due to criteria specified in the standby letter of credit.  A typical arrangement involves the applicant routinely being indebted to the beneficiary for such items as inventory purchases, insurance, utilities, lease guarantees or other third party commercial transactions.  The standby letter of credit would permit the beneficiary to obtain payment from Pinnacle Financial under certain prescribed circumstances.  Subsequently, Pinnacle Financial would then seek reimbursement from the applicant pursuant to the terms of the standby letter of credit. At September 30, 2017,March 31, 2018, these commitments amounted to $137.3$150.9 million.

Pinnacle Financial typically follows the same credit policies and underwriting practices when making these commitments as it does for on-balance sheet instruments. Each customer's creditworthiness is typically evaluated on a case-by-case basis, and the amount of collateral obtained, if any, is based on management's credit evaluation of the customer. Collateral held varies but may include cash, real estate and improvements, marketable securities, accounts receivable, inventory, equipment and personal property.

The contractual amounts of these commitments are not reflected in the consolidated financial statements and only amounts drawn upon would be reflected in the future.  Since many of the commitments are expected to expire without being drawn upon, the contractual amounts do not necessarily represent future cash requirements.  However, should the commitments be drawn upon and should Pinnacle Financial's customers default on their resulting obligation to Pinnacle Financial, the maximum exposure to credit loss, without consideration of collateral, is represented by the contractual amount of those commitments. At September 30, 2017both March 31, 2018 and December 31, 2016,2017, Pinnacle Financial had accrued $3.1 million and $1.1 million, respectively, for the inherent risks associated with these off-balance sheet commitments.

Various legal claims also arise from time to time in the normal course of business.  In the opinion of management, the resolution of these claims outstanding at September 30, 2017March 31, 2018 will not have a material adverse impact on Pinnacle Financial's consolidated financial condition, operating results or cash flows.

The 20142018 Plan also permits Pinnacle Financial to reissue awards currently outstanding that are subsequently forfeited, settled in cash, withheld by Pinnacle Financial to cover withholding taxes or expired unexercised and returned to the 20142018 Plan.

The BNC Bancorp 2013 Amended and Restated Omnibus Stock Incentive Plan (the "BNC Plan") was assumed by Pinnacle Financial in connection with the BNC Merger. As of March 31, 2018, the BNC Plan had approximately 9,000 shares remaining available for issuance to existing associates that were previously BNC associates in future periods. No new awards may be granted under plans other than the 2018 Plan except for shares remaining available for issuance to the former BNC associates pursuant to the BNC Plan.

No further shares remain available for issuance under the CapitalMark Option Plan. Approximately 33,000 shares remain available for issuance to existing BNC associates in future periods, related to the BNC Plan. No options were assumed upon the acquisition of Magna, Avenue or BNC as all preexisting Magna, Avenue and BNC stock options were converted to cash upon acquisition.

Note 9. Derivative Instruments

Financial derivatives are reported at fair value in other assets or other liabilities. The accounting for changes in the fair value of a derivative depends on whether it has been designated and qualifies as part of a hedging relationship. For derivatives not designated as hedges, the gain or loss is recognized in current period earnings.

Non-hedge derivatives

Pinnacle Financial enters into interest rate swaps (swaps) to facilitate customer transactions and meet their financing needs. Upon entering into these instruments to meet customer needs, Pinnacle Financial enters into offsetting positions in order to minimize the risk to Pinnacle Financial. These swaps are derivatives, but are not designated as hedging instruments. A summary of Pinnacle Financial's interest rate swaps related to customers as of September 30, 2017March 31, 2018 and December 31, 20162017 is included in the following table (in thousands):

Derivatives designated as cash flow hedges

For derivative instruments that are designated and qualify as a cash flow hedge, the aggregate fair value of the derivative instrument is recorded in other assets or other liabilities with any gain or loss related to changes in fair value recorded in accumulated other comprehensive income, net of tax. The gain or loss is reclassified into earnings in the same period during which the hedged asset or liability affects earnings and is presented in the same income statement line item as the earnings effect of the hedged asset or liability. Pinnacle Financial uses forward cash flow hedge relationships in an effort to manage future interest rate exposure. The hedging strategy converts the LIBOR-based variable interest rate on forecasted borrowings to a fixed interest rate and is used in an effort to protect Pinnacle Financial from floating interest rate variability.

Each of these swaps were terminated via cash settlement in the second quarter of 2017. As a result of terminating these contracts in the second quarter of 2017, Pinnacle Financial began recognizing a gain of $3.1 million over the original terms of these agreements.

The cash flow hedges were determined to be fullyhighly effective during the periods presented. Therefore, no amount of ineffectiveness has been included in net income. The aggregate fair value of the swaps is recorded in other assets or other liabilities with changes in fair value recorded in accumulated other comprehensive (loss) income, net of tax.presented and as a result qualify for hedge accounting treatment. If a hedge was deemed to be ineffective, the amount included in accumulated other comprehensive (loss) income would be reclassified into a line item within the statement of income that impacts operating results. The hedge would no longer be considered effective if a portion of the hedge becomes ineffective, the item hedged is no longer in existence or Pinnacle Financial discontinues hedge accounting. Other than the interest rate swaps agreements terminated in the second quarter of 2017, Pinnacle Financial expects the hedges to remain fullycontinue to be highly effective and qualify for hedge accounting during the remaining terms of the swaps. Pinnacle Financial does not expect anyNo amounts were reclassified from accumulated other comprehensive income into net income related to these derivatives during the three months ended March 31, 2018 or 2017, and no amounts are expected to be reclassified from accumulated other comprehensive (loss) income related to these swapsinto net income over the next twelve months.

Derivatives designated as fair value hedges

For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged asset or liability attributable to the hedged risk are recognized in current earnings. The gain or loss on the derivative instrument is presented on the same income statement line item as the earnings effect of the hedged item. Pinnacle Financial utilizes interest rate swaps designated as fair value hedges to mitigate the effect of changing interest rates on the fair values of fixed rate callable securities available-for-sale. The hedging strategy converts the fixed interest rates on the securities to LIBOR-based variable interest rates. These derivatives are designated as partial term hedges of selected cash flows covering specified periods of time prior to the call dates of the hedged securities. Pinnacle Financial has elected early adoption of FASB ASU 2017-12, which allows such partial term hedge designations.

In April 2018, Pinnacle Financial executed additional swap transactions with a notional amount of $525 million designated as fair value hedges. These derivatives are intended to protect against the effects of changing interest rates on the fair values of fixed rate prepayable loans. As allowed under FASB ASU 2017-12, a specified portion of the prepayable loans have been designated as the hedged assets under the "last-of-layer" method. Such hedging designations are allowed on the portion of a closed portfolio of prepayable assets that is not expected to be affected by prepayments, defaults, and other factors affecting the timing and amount of cash flows.

Note 10. Fair Value of Financial Instruments

FASB ASC 820, Fair Value Measurements and Disclosures, which defines fair value, establishes a framework for measuring fair value in U.S. GAAP and expands disclosures about fair value measurements.  The definition of fair value focuses on the exit price, i.e., the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, not the entry price, i.e., the price that would be paid to acquire the asset or received to assume the liability at the measurement date.  The statement emphasizes that fair value is a market-based measurement; not an entity-specific measurement.  Therefore, the fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability.

Valuation Hierarchy

FASB ASC 820 establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows:

Level 1 – inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3 – inputs to the valuation methodology are unobservable and significant to the fair value measurement.

A financial instrument's categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. FollowingThe following is a description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy.

Assets


Securities available-for-sale – Where quoted prices are available for identical securities in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities include highly liquid government securities and certain other financial products. If quoted market prices are not available, then fair values are estimated by using pricing models that use observable inputs or quoted prices of securities with similar characteristics and are classified within Level 2 of the valuation hierarchy. In certain cases where there is limited activity or less transparency around inputs to the valuation and more complex pricing models or discounted cash flows are used, securities are classified within Level 3 of the valuation hierarchy.

Other investments – Included in other assets are other investments recorded at fair value primarily in certain nonpublic private equityinvestments and funds. The valuation of these nonpublic private equity investments requires management judgment due to the absence of observable quoted market prices, inherent lack of liquidity and the long-term nature of such assets. These investments are valued initially based upon transaction price. The carrying values of other investments are adjusted either upwards or downwards from the transaction price

to reflect expected exit values as evidenced by financing and sale transactions with third parties, or when determination of a valuation adjustment is confirmed through ongoing reviews by senior investment managers. A variety of factors are reviewed and monitored to assess positive and negative changes in valuation including, but not limited to, current operating performance and future expectations of the particular investment, industry valuations of comparable public companies and changes in market outlook and the third-party financing environment over time. In determining valuation adjustments resulting from the investment review process, emphasis is placed on current company performance and market conditions. These investments are included in Level 3 of the valuation hierarchy as these entities and funds are not widely traded and the underlying investments of such funds are often privately-held and/or start-up companies for which market values are not readily available.

Other assets – Included in other assets are certain assets carried at fair value, including interest rate swap agreements, the cash flow hedge agreements and interest rate locks associated with the mortgage loan pipeline.  The carrying amount of interest rate swap agreements is based on Pinnacle Financial's pricing models that utilize observable market inputs. The fair value of the cash flow hedge agreements is determined by calculating the difference between the discounted fixed rate cash flows and the discounted variable rate cash flows.  The fair value of the mortgage loan pipeline is based upon the projected sales price of the underlying loans, taking into account market interest rates and other market factors at the measurement date, net of the projected fallout rate.  Pinnacle Financial reflects these assets within Level 2 of the valuation hierarchy as these assets are valued using similar transactions that occur in the market.

NonaccrualImpaired loans – A loan is classified as nonaccrualimpaired when it is probable Pinnacle Financial will be unable to collect all principal and interest payments due in accordance with the contractual terms of the loan agreement. NonaccrualImpaired loans are measured based on the present value of expected payments using the loan's original effective rate as the discount rate, the loan's observable market price, or the fair value of the collateral less selling costs if the loan is collateral dependent. If the recorded investment in the nonaccrualimpaired loan exceeds the measure of fair value, a valuation allowance may be established as a component of the allowance for loan losses or the difference may be recognized as a charge-off. NonaccrualImpaired loans are classified within Level 3 of the hierarchy due to the unobservable inputs used in determining their fair value such as collateral values and the borrower's underlying financial condition.

Other real estate owned – Other real estate owned (OREO) represents real estate foreclosed upon by Pinnacle Bank through loan defaults by customers or acquired by deed in lieu of foreclosure. Substantially all of these amounts relate to lots, homes and development projects that are either completed or are in various stages of construction for which Pinnacle Financial believes it has adequate collateral. Upon foreclosure, the property is recorded at the lower of cost or fair value, based on appraised value, less selling costs estimated as of the date acquired with any loss recognized as a charge-off through the allowance for loan losses. Additional OREO losses for subsequent valuation downward adjustments are determined on a specific property basis and are included as a component of noninterest expense along with holding costs. Any gains or losses realized at the time of disposal are also reflected in noninterest expense, as applicable. OREO is included in Level 3 of the valuation hierarchy due to the lack of observable market inputs into the determination of fair value. Appraisalvalue as appraisal values are property-specific and sensitive to the changes in the overall economic environment.

Liabilities

Other liabilities – Pinnacle Financial has certain liabilities carried at fair value including certain interest rate swap agreements to facilitate customer transactions and the cash flow hedge and interest rate locks associated with the funding for its mortgage loan originations. The fair value of these liabilities is based on Pinnacle Financial's pricing models that utilize observable market inputs and is reflected within Level 2 of the valuation hierarchy.

In the case of the investment securities portfolio, Pinnacle Financial monitors the portfolio to ascertain when transfers between levels have been affected.  The nature of the remaining assets and liabilities is such that transfers in and out of any level are expected to be rare.  For the three and nine months ended September 30, 2017,March 31, 2018, there were no transfers between Levels 1, 2 or 3.


The table below includes a rollforward of the balance sheet amounts for the three and nine months ended September 30, 2017March 31, 2018 (including the change in fair value) for financial instruments classified by Pinnacle Financial within Level 3 of the valuation hierarchy measured at fair value on a recurring basis including changes in fair value due in part to observable factors that are part of the valuation methodology (in thousands):

The following methods and assumptions were used by Pinnacle Financial in estimating its fair value disclosures for financial instruments that are not measured at fair value. In cases where quoted market prices are not available, fair values are based on estimates using discounted cash flow models. Those models are significantly affected by the assumptions used, including the discount rates, estimates of future cash flows and borrower creditworthiness. The fair value estimates presented herein are based on pertinent information available to management as of September 30, 2017March 31, 2018 and December 31, 2016.2017. Such amounts have not been revalued for purposes of these consolidated financial statements since those dates and, therefore, current estimates of fair value may differ significantly from the amounts presented herein.

Securities held-to-maturity - Estimated fair values for investment securities are based on quoted market prices where available.  If quoted market prices are not available, then fair values are estimated by using pricing models that use observable inputs or quoted prices of securities with similar characteristics.

Loans net - The fair value of ourPinnacle Financial's loan portfolio includes a credit risk factor in the determination of the fair value of ourits loans.  This credit risk assumption is intended to approximate the fair value that a market participant would realize in a hypothetical orderly transaction.  OurPinnacle Financial's loan portfolio is initially fair valued using a segmented approach. We divide ourPinnacle Financial divides its loan portfolio into the following categories: variable rate loans, impaired loans and all other loans. The results are then adjusted to account for credit risk.

For variable-rate loans that reprice frequently and have no significant change inThe values derived from the discounted cash flow approach for our performing loan portfolio incorporate credit risk fair values approximate carrying values.to determine the exit price. Fair values for impaired loans are estimated using discounted cash flow models or based on the fair value of the underlying collateral.  For other

All other purchased loans are recorded at their initial fair value, and adjusted for subsequent advances, pay downs, amortization or accretion of any fair value premium or discount on purchase, charge-offs and any other adjustment to incorporate credit risk to determine the exit price.carrying value.

Mortgage loansLoans held-for-sale - Mortgage loansLoans held-for-sale are carried at the lower of cost or fair value.  The estimate of fair value is based on pricing models and other information.

Deposits, securities sold under agreements to repurchase, Federal Home Loan Bank (FHLB) advances, subordinated debt and other borrowings - The fair value of demand deposits, savings deposits and securities sold under agreements to repurchase are derived from a selection of market transactions reflecting our peer group. Fair values for certificates of deposit, FHLB advances and subordinated debt are estimated using discounted cash flow models, using current market interest rates offered on certificates, advances and other borrowings with similar remaining maturities.


Off-balance sheet instruments - The fair values of Pinnacle Financial's off-balance-sheet financial instruments are based on fees charged to enter into similar agreements. However, commitments to extend credit do not represent a significant value to Pinnacle Financial until such commitments are funded.

The following table presents the carrying amounts, estimated fair value and placement in the fair value hierarchy of Pinnacle Financial's financial instruments at September 30, 2017March 31, 2018 and December 31, 2016.2017.  This table excludes financial instruments for which the carrying amount approximates fair value.  For short-term financial assets such as cash and cash equivalents, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization.  For financial liabilities such as non-interest bearing demand, interest-bearing demand, and savings deposits, the carrying amount is a reasonable estimate of fair value due to these products having no stated maturity (in thousands):

(1)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.
(2)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 September 30, 2017March 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.

2016, Pinnacle Financial included in other liabilities $2.3 million and $383,000, respectively, representing the inherent risks associated with these off-balance sheet commitments.
(3)At September 30, 2017March 31, 2018 and December 31, 2016,2017, the aggregate fair value of Pinnacle Financial's standby letters of credit was $785,000$1.1 million and $740,000,$800,000, respectively. This amount representsThese amounts represent the unamortized fee associated with these standby letters of credit and isare included in the consolidated balance sheetsheets of Pinnacle Financial and isare believed to approximate fair value. ThisThese fair valuevalues will decrease over time as the existing standby letters of credit approach their expiration dates.


Note 11. Regulatory Matters

Pursuant to Tennessee banking law, Pinnacle Bank may not, without the prior consent of the Commissioner of the Tennessee Department of Financial Institutions (TDFI), pay any dividends to Pinnacle Financial in a calendar year in excess of the total of Pinnacle Bank's retained net income for that year plus the retained net income for the preceding two years. During the ninethree months ended September 30, 2017,March 31, 2018, Pinnacle Bank paid $38.1$25.1 million in dividends to Pinnacle Financial. Since the first quarter of 2016, Pinnacle Financial has paid a quarterly common stock dividend of $0.14 per share. The amount and timing of all future dividend payments by Pinnacle Financial, if any, is subject to discretion of Pinnacle Financial's board of directors and will depend on Pinnacle Financial's earnings, capital position, financial condition and other factors, including then applicable regulatory capital requirements, as they become known to Pinnacle Financial and Pinnacle Bank's ability to pay dividends to Pinnacle Financial.

Pinnacle Financial and Pinnacle Bank are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on the financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, Pinnacle Financial and Pinnacle Bank must meet specific capital guidelines that involve quantitative measures of the assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. Pinnacle Financial's and Pinnacle Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Quantitative measures established by regulation to ensure capital adequacy require Pinnacle Financial and its banking subsidiary to maintain minimum amounts and ratios of common equity Tier 1 capital to risk-weighted assets, Tier I capital to risk-weighted assets, total risk-based capital to risk-weighted assets and of Tier 1 capital to average assets.

The final rules implementing the Basel Committee on Banking Supervision's capital guidelines for U.S. banks (Basel III rules) became effective for Pinnacle Financial on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019. The minimum capital level requirements applicable to bank holding companies and banks subject to the rules are: (i) a common equity Tier 1 capital ratio of 4.5%; (ii) a Tier 1 risk-based capital ratio of 6%; (iii) a total risk-based capital ratio of 8%; and (iv) a Tier 1 leverage ratio of 4% for all institutions. The Basel III rules also establish a capital conservation buffer of 2.5% (to be phased in over three years) above the regulatory minimum risk-based capital ratios. The capital conservation buffer was phased in beginning in January 2016 at 0.625% and is increasing each year by a like percentage until fully implemented in January 2019. The net unrealized gain or loss on available-for-sale securities is not included in computing regulatory capital. Management believes, as of September 30, 2017,March 31, 2018, that Pinnacle Financial and Pinnacle Bank met all capital adequacy requirements to which they are subject. To be categorized as well-capitalized under applicable banking regulations, Pinnacle Financial and Pinnacle Bank must maintain minimumcertain total risk-based, Tier 1 risk-based, common equity Tier 1 and Tier 1 leverage ratios as set forth in the following table and not be subject to a written agreement, order or directive to maintain a higher capital level. Pinnacle Financial's and Pinnacle Bank's actual capital amounts and resulting ratios, not including the capital conservation buffer, are presented in the following table (in thousands):

Though these securities no longer qualify as Tier 1 capital from and after the closing of the merger, Pinnacle Financial believes these subordinated debentures continue to qualify as Tier 2 capital.
ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following is a discussion of our financial condition at September 30, 2017March 31, 2018 and December 31, 20162017 and our results of operations for the three and nine months ended September 30, 2017March 31, 2018 and 2016.2017.  The purpose of this discussion is to focus on information about our financial condition and results of operations which is not otherwise apparent from our consolidated financial statements.  The following discussion and analysis should be read along with our consolidated financial statements and the related notes included elsewhere herein.

Overview

Our diluted net income per common share for the three and nine months ended September 30, 2017March 31, 2018 was $0.83 and $2.46$1.08 compared to $0.71 and $2.12$0.82 for the same periodsperiod in 2016.2017. At September 30, 2017,March 31, 2018, loans had increased to $15.26$16.33 billion, as compared to $8.45$15.63 billion at December 31, 2016,2017, and total deposits increased to $15.79$16.50 billion at September 30, 2017March 31, 2018 from $8.76$16.45 billion at December 31, 2016.2017. The comparability of our financial condition and performance for the three month period ended March 31, 2018 compared to the comparable period in 2017 has been impacted by the July 1, 2016 acquisition of Avenue Financial Holdings, Inc. (Avenue) and the June 16, 2017 acquisition of BNC Bancorp (BNC).

Acquisitions.BNC Acquisition. We acquired a 30% membership interest in Bankers Healthcare Group, LLC (BHG) on February 1, 2015 for $75.0 million in cash and acquired an additional 19% membership interest in BHG on March 1, 2016 for $74.1 million in cash and 860,470 shares of Pinnacle Financial common stock, with a fair value of $39.9 million on the date of the acquisition. We acquired CapitalMark Bank and Trust (CapitalMark) on July 31, 2015 and Magna Bank (Magna) on September 1, 2015.

We acquired Avenue and its bank subsidiary Avenue Bank on July 1, 2016. At the acquisition date, Avenue had net assets valued at $81.7 million, including loans of $952.5 million and deposits valued at $966.7 million. The Avenue acquisition further expanded our franchise into our Tennessee market. We acquired BNC on June 16, 2017. At the acquisition date, BNC's net assets were preliminarily fair valued at $607.3$601.5 million, including loans valued at $5.60 billion and deposits valued at $6.21 billion. This acquisition expanded our footprint into the Carolinas and Virginia.
 
Our merger with BNC was consummated on June 16, 2017. Each holder of BNC common stock (including restricted shares) received 0.5235 shares of Pinnacle Financial's common stock for each share of BNC common stock held by each shareholder on the closing date. We issued 27,687,100 shares of common stock and paid cash consideration of approximately $129,000, related to fractional shares, to the BNC shareholders. Included in the common stock issued were 136,890 assumed shares of unvested restricted stock that will continue to vest over their original contractual terms. The fair value of these awards was $9.2 million, with $5.4 million attributable to precombination services provided by the recipients prior to the merger, that accordingly was included as merger consideration.

Tax Cuts and Jobs Act. On December 22, 2017, the Tax Cuts and Jobs Act was signed into law. Among other items, the Tax Cuts and Jobs Act reduced the corporate Federal tax rate from 35% to 21%. As a result of such decrease, we recognized a charge of $31.5 million in the fourth quarter of 2017 resulting from the revaluation of our deferred tax assets.

Under the Tax Cuts and Jobs Act, the qualified performance-based compensation exception to Section 162(m) that generally provided for the continued deductibility of performance-based compensation was repealed, effective for tax years commencing on or after January 1, 2018. Accordingly, commencing with our fiscal year ending December 31, 2018, compensation to our named executive officers in excess of $1,000,000 not awarded as performance-based compensation prior to November 2, 2017 will generally not be deductible, which will likely partially offset the expected reduction in our income tax expense resulting from the rate cut under the Tax Cuts and Jobs Act. Performance based compensation (meeting the requirements of Section 162(m) prior to amendment with the Tax Cuts and Jobs Act) that is earned on awards issued pursuant to binding agreements in effect as of November 2, 2017 will retain its status as tax deductible.
 
Results of Operations. Our net interest income increased to $173.2 million and $368.6$174.5 million for the three and nine months ended September 30, 2017, respectively,March 31, 2018 compared to $86.6 million and $235.6$88.8 million for the same periodsperiod in the prior year, representing

increases an increase of $86.6$85.7 million, and $133.0 million, respectively.largely as a result of our merger with BNC as well as continued loan growth in our Tennessee markets. The net interest margin (the ratio of net interest income to average earning assets) for the three and nine months ended September 30, 2017March 31, 2018 was 3.87% and 3.75%, respectively,3.77% compared to 3.60% and 3.69%, respectively, for the same periodsperiod in 2016.2017.
 
Our provision for loan losses was $6.9 million and $17.4 million, respectively, for the three and nine months ended September 30, 2017March 31, 2018 compared to $6.1 million and $15.3$3.7 million for the same periodsperiod in 2016.2017. Net charge-offs were $3.7$4.0 million and $11.2 million, respectively, for the three and nine months ended September 30, 2017,March 31, 2018 compared to $7.3$4.3 million and $20.5 million, respectively, for the same periodsperiod in 2016.2017. Provision expense for both periods was negatively impacted by organic loan growth and by charge-offs realized in our consumer portfolio, primarily related to non-prime automobile loans.
Our
At March 31, 2018, our allowance for loan losses as a percentage of total loans decreasedremained unchanged from 0.70%0.43% at December 31, 2016 to 0.43% at September 30, 2017. The decrease in thecalculated allowance for loan losses as a percentage of total loans is primarily attributable toimpacted by the acquired BNC loan portfolioportfolios being accounted for at its fair value as of the merger date. For the BNC loan portfolio, a preliminary fair value discount of $181.4 million was determined as of the acquisition date. At September 30, 2017,March 31, 2018, the remaining fair value discount for all acquired portfolios (inclusive of BNC) was $182.4$148.9 million. For loans acquired in connection with our mergers, the calculation of the allowance for loan losses subsequent to the acquisition date is consistent with that utilized for legacy Pinnacle Financial loans. Our accounting policy is to compare the computed allowance for loan losses on purchased loans to the remaining fair value adjustment at the individual loan level. Generally the fair value adjustments are expected to accrete to interest income over the remaining expected life of the underlying loan agreements and decrease proportionately with the related loan balance. However, if the computed allowance is greater than the remaining fair value adjustment, the excess is added to the allowance for loan losses by a provision for loan losses. Additional provisioning for purchased portfolios results from credit deterioration on the individual loan or from increased borrowings on loans and lines that existed as of the acquisition date. Should a loan with a remaining fair value discount be paid off prior to maturity, the remaining fair value discount is recognized as interest income. As more fully discussed in the Critical Accounting Policies below, our allowance for loan loss methodology was modified during the quarter ended September 30, 2017.

Noninterest income increased by $11.3$13.8 million, and $18.2 million, respectively,or 45.4 percent, during the three and nine months ended September 30, 2017,March 31, 2018 compared to the same periodsperiod in 2016.2017. Income from equity method investment was $8.9$9.4 million and $25.5 million, respectively, for the three and nine months ended September 30, 2017March 31, 2018 compared to $8.5 million and $23.3$7.8 million for the same periodsperiod in the prior year. The nine months ended September 30, 2017, included nine months of earnings from BHG at a 49% ownership level compared to two months of earnings from BHG at a 30% ownership level and seven months of earnings at the 49% ownership level for the nine months ended September 30, 2016. Gains on mortgage loans sold increased $866,000 and $1.9 million over the three and nine month periods in the prior year due to the expanded footprint and continued strength in the local housing economy and continued favorable refinancing market conditions. The additional growth within noninterest income was attributable to increased loan swap fees and gains on bank owned life insurance, as well as increased contributions from our fee-based businesses such as investments, insurance and trust.trust, resulting from both organic growth and our merger with BNC as well as gains on bank owned life insurance.
Noninterest expense increased by $46.2$46.5 million, and $70.1 millionor 75.0 percent, during the three and nine months ended September 30, 2017,March 31, 2018 as compared to the three and nine months ended September 30, 2016,March 31, 2017, and reflects the impact of our July 1, 2016 acquisition of Avenue and June 16, 2017 acquisition ofmerger with BNC, resulting inthat contributed to increased salaries and employment benefits, increased equipment and occupancy costs due to our expanded retail network, and increased intangible amortization expense and merger-related charges. OurSalaries and employee benefits were $63.4 million for the three months ended March 31, 2018 compared to $38.4 million for the three months ended March 31, 2017. This increase primarily resulted from annual merit increases and the expansion of our associate base has expanded from 1,177.51,217.5 full-time equivalent associates at September 30, 2016March 31, 2017 to 2,194.52,148.0 full-time equivalent associates at September 30, 2017,March 31, 2018, due to both opportunistic hires and our acquisition of Avenue andmerger with BNC. At September 30, 2017,March 31, 2018, approximately 947744 full-time equivalent associates were deployed in the former BNC footprint. Merger-related charges for the three months ended March 31, 2018 were $5.4 million compared to $672,000 for the three months ended March 31, 2017. Merger-related charges incurred for the three months ended March 31, 2018 were associated with our merger with BNC and were inclusive of costs associated with associate retention packages and cultural and technology integrations.
During the three and nine months ended September 30, 2017,March 31, 2018, Pinnacle Financial recorded income tax expense of $35.1$19.6 million and $68.8 million, respectively, compared to $16.3 million and $45.9$13.8 million for the three and nine months ended September 30, 2016.March 31, 2017.  Pinnacle Financial's effective tax rate for the three and nine months ended September 30, 2017March 31, 2018 was 35.2% and 31.9%, respectively,19.0% compared to 33.5% and 33.5%, respectively,25.8% for the three and nine months ended September 30, 2016.March 31, 2017. Pinnacle Financial's effective tax rate differs from the combined federal and state income tax statutory rate applicable to Pinnacle Financial of 26.14% at March 31, 2018 and 39.23% at March 31, 2017 primarily due to the reduction in the federal statutory corporate tax rate following enactment of the Tax Cuts and Jobs Act, state excise tax expense, our investments in bank-qualified municipal securities, tax benefits from our real estate investment trust subsidiary, participation in Tennessee's Community Investment Tax Credit (CITC) program, tax benefits associated with bank-owned life insurance and tax savings from our captive insurance subsidiary, offset in part by the limitation on deductibility of meals and entertainment expense and certain merger-related expenses. We also recorded taxnon-deductible FDIC insurance premiums. Tax benefits associated with our equity-based compensation program recognized pursuant to the adoptionASU 2016-09 also reduced our effective tax rate in both periods and resulted in tax benefits of ASU 2016-09$2.7 million for the three and nine months ended September 30, 2017, resulting inMarch 31, 2018 compared to $3.8 million for the recognition of $59,000 and $4.6 million, respectively, of tax benefits.same period prior year. Prior to the adoption of ASU 2016-09, these tax benefits were recorded in the statement of stockholders' equity directly to additional paid-in-capital.

Financial Condition.  Reflecting a combination of organic growth due to continued economic growth in our core markets, increases in the number of relationship advisors and continued focus on attracting new customers to our acquisition of BNC,company, net loans increased $6.81 billion,$692.9 million, or 80.6%4.4%, during the ninethree months ended September 30, 2017,March 31, 2018, when compared to December 31, 2016. Similarly, total2017. Total deposits were $15.79$16.50 billion at September 30, 2017,March 31, 2018, compared to $8.76$16.45 billion at December 31, 2016,2017, an increase of $7.03 billion.$51.2 million.

Capital and Liquidity. At September 30,March 31, 2018 and December 31, 2017, our capital ratios, including our bank's capital ratios, exceeded regulatory minimum capital requirements and those levels necessary to be considered well-capitalized under applicable regulatory guidelines.federal regulations. See Note 11. Regulatory Matters in the Consolidated Financial Statements.
From time to time we may be required to support the capital needs of our bank (Pinnacle Bank). At September 30, 2017,March 31, 2018, we had approximately $47.1$79.8 million of cash at the holding company, substantially all of which could be used to support our bank. We believe we have various capital raising techniques available to us to provide for the capital needs of our company and bank, including an established a line of credit with another bank that can be utilized to provide up to $75 million of additional capital support to Pinnacle Bank, if needed.
Critical Accounting Estimates
The accounting principles we follow and our methods of applying these principles conform with U.S. GAAP and with general practices within the banking industry. There have been no significant changes to our Critical Accounting Policies as described in our Annual Report on Form 10-K for the year ended December 31, 2016 with the exception of changes to our policy for determining the allowance for loan losses which has been adjusted to better align the allowance with the current economic cycle and is described below.2017.

Allowance for Loan Losses (allowance).  Our management assesses the adequacy of the allowance prior to the end of each calendar quarter. This assessment includes procedures to estimate the allowance and test the adequacy and appropriateness of the resulting balance. The level of the allowance is based upon management's evaluation of the loan portfolio, loan loss experience, asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect the borrowers' ability to repay the loan (including the timing of future payment), the estimated value of any underlying collateral, composition of the loan portfolio, economic conditions, industry and peer bank loan quality indications and other pertinent factors, including regulatory recommendations.  The level of allowance maintained is believed by management to be adequate to absorb probable losses inherent in the loan portfolio at the balance sheet date. The allowance is increased by provisions charged to expense and decreased by charge-offs, net of recoveries of amounts previously charged-off.  Allocation of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management's judgment, is deemed to be uncollectible.

Our allowance for loan loss assessment methodology was modified in the quarter ended September 30, 2017 to (i) extend the lookback period from 24 quarters to a period beginning January 1, 2006 to better capture a complete economic cycle, (ii) eliminate the use of risk ratings in the calculation of the loss rate and instead focus on risk by loan type and (iii) expand the economic variables used in the qualitative assessment to incorporate our expanded footprint. We also eliminated the use of a loss emergence period in light of the minimal population of losses available to evaluate that were previously being extrapolated to the full population of loans, and shifted the focus of our analysis to more of a quantitative model. There was no material impact on the adoption of the change in the allowance for loan loss assessment methodology.

Our allowance for loan losses is composed of the result of two independent analyses pursuant to the provisions of ASC 450-20, Loss Contingencies and ASC 310-10-35, Receivables. The ASC 450-20 analysis is intended to quantify the inherent risks in our performing loan portfolio. The ASC 310-10-35 analysis includes a loan-by-loan analysis of impaired loans, both those reported as nonaccrual and troubled-debt restructurings.

In assessing the adequacy of the allowance, we also consider the results of our ongoing independent loan review process. We undertake this process both to ascertain those loans in the portfolio with elevated credit risk and to assist in our overall evaluation of the risk characteristics of the entire loan portfolio.  Our loan review process includes the judgment of management, independent internal loan reviewers, and reviews that may have been conducted by third-party reviewers primarily regulatory examiners. We incorporate relevant loan review results in the allowance.
The ASC 450-20 component of the allowance for loan losses begins with a historical loss rate calculation for each loan pool with similar risk characteristics. The losses realized over a rolling four-quarter cycle are utilized to determine an annual loss rate for each loan pool for each quarter-end in our look-back period. The look-back period in our loss rate calculation begins with January 2006, as we believe this period is representative of an economic cycle. The loss rates for each category are then averaged and applied to the end of period loan portfolio balances to determine estimated losses. The loss rates provide a quantitative estimate of credit losses inherent in our end of period loan portfolio based on our actual loss experience.

The estimated loan loss allocation for all loan segments also considers management's estimate of probable losses for a number of qualitative factors that have not been considered in the quantitative analysis. The qualitative categories and the measurements used to quantify the risks within each of these categories are subjectively selected by management, but measured by objective measurements period over period.  The data for each measurement may be obtained from internal or external sources.  The current period measurements are evaluated and assigned a factor commensurate with the current level of risk relative to past measurements over time. The resulting factor is applied to the non-impaired loan portfolio.  This amount represents estimated probable inherent credit losses which exist, but have not yet been identified either in our risk rating or impairment process, as of the balance sheet date, and is based upon quarterly trend assessments in portfolio concentrations, policy exceptions, economic conditions, associate retention, independent loan review results, collateral considerations, credit quality, competition and regulatory requirements, enterprise wide risk assessments, and peer group credit quality. The qualitative allowance allocation, as determined by the processes noted above, is increased or decreased for each loan segment based on the assessment of these various qualitative factors.
The allowance for loan losses for purchased loans is calculated similar to that utilized for our legacy loans. Our accounting policy is to compare the computed allowance for loan losses for purchased loans to any remaining fair value adjustment on a loan-by-loan basis. If the computed allowance is greater than the remaining fair value adjustment, the excess is added to the allowance for loan losses by a provision for loan losses.
The ASC 450-20 portion of the allowance also includes a small unallocated component.  We believe that the unallocated amount is warranted for inherent factors that cannot be practically assigned to individual loan categories, such as the imprecision in the overall loss allocation measurement process, the subjectivity risk of not considering all relevant environmental categories and related measurements and imprecision in our credit risk ratings process.  The appropriateness of the unallocated component of the allowance is assessed each quarter end based upon changes in the overall business environment not otherwise captured.
The second component of the allowance for loan losses is determined pursuant to ASC 310-10-35. Loans are impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement. Collection of all amounts due according to the contractual terms means collecting all interest and principal payments of a loan as scheduled in the loan agreement. This evaluation is inherently subjective as it requires material estimates including the amounts and timing of future cash flows expected to be received on impaired loans that may be susceptible to significant change. Loan losses are charged off when management believes that the full collectability of the loan is unlikely. A loan may be partially charged-off after a "confirming event" has occurred which serves to validate that full repayment pursuant to the terms of the loan is unlikely.

An impairment allowance is recognized if the fair value of the loan is less than the recorded investment in the loan (recorded investment in the loan is the principal balance plus any accrued interest, net of deferred loan fees or costs and unamortized premium or discount). The impairment is recognized through the provision for loan losses and is a component of the allowance. Loans that are impaired are recorded at the present value of expected future cash flows discounted at the loan's effective interest rate, or if the loan is collateral dependent, at the fair value of the collateral, less estimated disposal costs. If the loan is collateral dependent, the principal balance of the loan is charged-off in an amount equal to the impairment measurement. The fair value of collateral dependent loans is derived primarily from collateral appraisals performed by independent third-party appraisers.  Management believes it follows appropriate accounting and regulatory guidance in determining impairment and accrual status of impaired loans.
Pursuant to the guidance set forth in ASU No. 2011-02, A Creditor's Determination of Whether a Restructuring is a Troubled Debt Restructuring, the above impairment methodology is also applied to those loans identified as troubled debt restructurings.
We then test the resulting allowance by comparing the balance in the allowance to historical trends and industry and peer information. Our management then evaluates the result of the procedures performed, including the results of our testing, and decides on the appropriateness of the balance of the allowance in its entirety. The audit committee of our board of directors approves the allowance for loan loss policy annually and reviews the methodology and approves the resultant allowance prior to the filing of quarterly and annual financial information.

While our policies and procedures used to estimate the allowance for loan losses, as well as the resultant provision for loan losses charged to operations, are considered adequate by management and are reviewed from time to time by our regulators, they are necessarily approximate and inherently imprecise. There are factors beyond our control, such as conditions in the local, national, and international economy, a local real estate market or particular industry conditions which may negatively impact materially our asset quality and the adequacy of our allowance for loan losses and thus the resulting provision for loan losses.

Net Interest Income.  Net interest income represents the amount by which interest earned on various earning assets exceeds interest paid on deposits and other interest-bearing liabilities and is the most significant component of our revenues. Net interest income totaled $173.2$174.5 million and $368.6 million, respectively, for the three and nine months ended September 30, 2017,March 31, 2018, an increase of $86.6 million and $133.0$85.7 million from the levels recorded in the same periodsperiod of 2016. We were able to increase net interest income during the three and nine months ended September 30, 2017, comparedattributable to the same periodsgrowth in 2016 due primarily to our focus on growing our loan portfolio both organicallydue to our merger with BNC, organic growth, and an increase in the interest rates we receive on interest earning assets, offset in part by acquisition; this growth was partially offset byincreases in the rates we pay on deposits and our increasedother funding costs.sources. Average loans for the three and nine months ended September 30, 2017March 31, 2018 were 82.4% and 52.2%86.5% greater than average loan balances for the same periodsperiod in 2016.2017.

For the three and nine months ended September 30, 2017,March 31, 2018, our net interest margin was 3.87% and 3.75%, respectively,3.77% compared to 3.60% and 3.69% for the three and nine months ended September 30, 2016,March 31, 2017, respectively. Although our net interest margin for the three and nine month periodsthree-month period ended September 30, 2017,March 31, 2018 was positively impacted by increasesyield expansion in our earning assets,asset portfolio, these increases were partially offset by increases in our total funding costs. Increased levels of on balance sheet liquidity also negatively impactedDuring the three months ended March 31, 2018, total funding rates increased by 25 basis points compared to the three months ended March 31, 2017. The increase in our netcore funding costs was caused by our higher prevailing market interest marginrates, BNC acquisition as BNC's deposit rates were higher than our rates in the current year periods.our Tennessee markets and increased FHLB Cincinnati borrowings and subordinated debt, which have higher interest rates than our deposits. The expansion of our earning asset yields was driven in part by the impact of recent Federal funds rate increases, which positively impacted our floating and variable rate loan and investment portfolios. With our expected continued growth, we anticipate our net interest income will likely increase over the next several quarters. The application of fair value accounting on the BNC accounts we acquired also positively impacted our net interest margin for the three months ended March 31, 2018, albeit less than in the second and third quarters of 2017 but thismost closely following the merger. This impact should continue to lessen in future periods.

We continue to deploy various asset liability management strategies to manage our risk to interest rate fluctuations. We believe our net interest margin should remain relatively stable during the remainder of 2018. Although the further anticipated rise in interest rates should be beneficial to us, loan pricing for creditworthy borrowers is very competitive in our markets and may limit our ability to increase pricing on new and renewed loans. We also expect the impact of purchase accounting on our net interest income will continue to decrease in future periods. We anticipate that this challenging competitive environment will continue during the remainder of 2018 and it is unclear what impact the reduction in corporate tax rates under the Tax Cuts and Jobs Act will have on the demand for and the interest rates we charge for loans or pay on deposits. However, we believe our net interest income should continue to increase throughout the remainder of 2017in 2018 compared to 20162017 primarily due to an increase in average earning asset volumes, including the earning assets we acquired in connection with the BNC transaction.both loans and our securities portfolio. We anticipate fundingseek to fund these increased earning assets by growing our core deposits, but will utilize wholesale and utilizing limited wholesaleother forms of noncore funding to fund anya shortfall, if any, resulting from loan growth outpacing deposit growth.any.

Provision for Loan Losses.  The provision for loan losses represents a charge to earnings necessary to establish an allowance for loan losses that, in management's evaluation, should be adequate to provide coverage for the inherent losses on outstanding loans. Based upon management's assessment of the loan portfolio, we adjust our allowance for loan losses to an amount deemed appropriate to adequately cover probable losses inherent in the loan portfolio. OurAt March 31, 2018, our allowance for loan losses as a percentage of total loans decreasedremained unchanged from 0.70%0.43% at December 31, 2016 to 0.43% at September 30, 2017, largely driven by continued favorable credit experience in our larger portfolios and is supported by the acquired BNC loan portfoliostrong economies in the markets in which was recorded at fair value at the acquisition date.we operate.

The provision for loan losses amounted to $6.9 million and $17.4 million, respectively, for the three and nine months ended September 30, 2017March 31, 2018 compared to $6.1$3.7 million and $15.3 million, respectively, for the three and nine months ended September 30, 2016.March 31, 2017. Provision expense is impacted by the absolute level of loans, loan growth, the credit quality of the loan portfolio and the amount of net charge-offs. Provision expense in the most recent period continued to be negatively impacted by charge-offs realized in our consumer portfolio, primarily related to non-prime automobile loans.

Noninterest Income.  Our noninterest income is composed of several components, some of which vary significantly between quarterly and annual periods. Service charges on deposit accounts and other noninterest income generally reflect customer growth trends, while fees from our wealth management departments, the origination of mortgage loans, income from our equity method investment and gains and losses on the sale of securities will often reflect financial market conditions and fluctuate from period to period.

The increase in service charges on deposit accounts in the three and nine months ended September 30, 2017March 31, 2018 compared to the three and nine months ended September 30, 2016March 31, 2017 is primarily related to increased analysis fees due to an increase in the volume and number of commercial checking accounts.accounts resulting from our acquisition of BNC.
 
Income from our wealth management groups (investments, insurance and trust) is also included in noninterest income. For the three and nine months ended September 30, 2017,March 31, 2018, commissions and fees from investment services at our financial advisory unit, Pinnacle Asset Management, a division of Pinnacle Bank, increased by $1.1 million and $2.2$2.3 million as compared to the three and nine months ended September 30, 2016.March 31, 2017. At September 30,March 31, 2018 and 2017, and 2016, Pinnacle Asset Management was receiving commissions and fees in connection with approximately $3.0$3.5 billion and $2.1$2.3 billion, respectively, in brokerage assets.

The growth in our wealth management businesses is attributable to our expanded associate base and distribution platform in our new markets.

Gains on mortgage loans sold, net, consists of fees from the origination and sale of mortgage loans. These mortgage fees are for loans originated in our markets that are subsequently sold to third-party investors. Substantially all of these loan sales transfer servicing rights to the buyer. Generally, mortgage origination fees increase in lower interest rate environments and more robust housing markets and decrease in rising interest rate environments and more challenging housing markets. Mortgage origination fees will fluctuate from quarter to quarter as the rate environment changes. Gains on mortgage loans sold, net, were $6.0 million and $14.8$3.7 million for the three and nine months ended September 30, 2017March 31, 2018 as compared to $5.1 million and $12.9$4.2 million for the same periodsperiod in the prior year, reflectingyear. We hedge a portion of our expanded operations.mortgage pipeline as part of a mandatory delivery program. There is a strong positive correlation between the size of the mortgage pipeline and the value of this hedge. The hedge is not designated as a hedge for GAAP purposes and, as such, changes in its fair value are recorded directly through the income statement. Therefore, the size of the outstanding mortgage pipeline at any reporting period will directly impact the amount of revenue recorded for mortgage loans held for sale in any one period and is cyclical in nature. An overall increase in the volume of loans included in the mortgage pipeline typically results in a gain on the change in the fair market value of the hedge. Decreases in the volume of loans included in the mortgage pipeline are likely to negatively impact the gains we recognize as a result of this program.


Income from equity-method investment is comprised solely of income from our 49% equity-method investment in BHG. We acquired a 30% investment during the first quarter of 2015 and subsequently increased our investment to 49% in the first quarter of 2016. Income from this equity-method investment was $8.9$9.4 million and $25.5 million, respectively, for the three and nine months ended September 30, 2017March 31, 2018 compared to $8.5 million and $23.3$7.8 million for the same periodsperiod last year. Income from equity-method investment is recorded net of associated expenses, including amortization expense associated with customer lists and other intangible assets of $832,000 and $2.5 million, respectively,$693,000 for the three and nine months ended September 30, 2017March 31, 2018 compared to $1.5 million and $2.4 million, respectively,$832,000 for the three and nine months ended September 30, 2016.March 31, 2017. At September 30, 2017,March 31, 2018, there were $14.3$12.7 million of these intangible assets which will be amortized in lesser amounts over the next 1817 years.  Also included in income from equity-method investment, is accretion income associated with the fair valuation of certain of BHG's liabilities of $758,000 and $2.3 million, respectively,$742,000 for the three and nine months ended September 30, 2017,March 31, 2018, compared to $599,000 and $1.8 million, respectively,$806,000 for the three and nine months ended September 30, 2016.March 31, 2017. At September 30, 2017,March 31, 2018, there were $11.0$9.5 million of these liabilities which will be accreted into income in lesser amounts over the next 98 years.

During the three months ended March 31, 2018, Pinnacle Financial and Pinnacle Bank received dividends from BHG of $4.3 million in the aggregate compared to $2.5 million for the same period in the prior year, which reduced the carrying amount of our investment in BHG while earnings from BHG increase the carrying amount of our investment in BHG. Our proportionate share of earnings from BHG are included in our consolidated tax return. Profits from intercompany transactions are eliminated. Earnings from BHG may fluctuate from period-to-period. No loans were purchased from BHG by Pinnacle Bank for the three-month periods ended March 31, 2018 or 2017, respectively.

As our ownership interest in BHG is 49%, we do not consolidate BHG's results of operations or financial position into our financial statements but record the net result of BHG's activities at our percentage ownership in income from equity method investment in noninterest income.  For the three and nine months ended September 30, 2017,March 31, 2018, BHG reported $42.0$43.8 million and $113.2 million, respectively, in revenues, net of substitution losses of $9.1$11.3 million and $31.9 million, respectively, compared to revenues of $37.6$34.2 million and $108.2 million, respectively, for the three and nine months ended September 30, 2016,March 31, 2017, net of substitution losses of $6.4 million and $16.4 million, respectively.$11.2 million.

Approximately $33.5$35.1 million and $89.6 million, respectively, of BHG's revenues for the three and nine months ended September 30, 2017March 31, 2018 related to gains on the sale of commercial loans BHG had previously issued to doctor, dentist and other medical and professional practices compared to $27.7$26.8 million and $73.9 million, respectively, for the three and nine months ended September 30, 2016.March 31, 2017. BHG refers to this activity as its core product. BHG typically funds these loans from cash reserves on its balance sheet. Subsequent to origination, these core product loans are sold by BHG with limited or no recourse to a network of community banks and other financial institutions at a premium to the par value of the loan. The purchaser may access a BHG cash reserve account of up to 3% of the loan balance to support loan payments.  BHG retains no servicing or other responsibilities related to the core product loan once sold. As a result, this gain on sale premium represents BHG's compensation for absorbing the costs to originate the loan as well as marketing expenses associated with maintaining its business model. At September 30, 2017,March 31, 2018, there were $1.4$1.6 billion in core product loans previously sold by BHG that were being actively serviced by BHG's bank network of purchasers. 

Traditionally, BHG, at its sole option, may also provide purchasers of these core product loans the ability to substitute the acquired loan with another more recently-issued BHG loan should the previously-acquired loan become at least 90-days past due as to its monthly payments. This substitution is subject to the purchaser having adhered to the standards of its purchase agreement with BHG. Additionally, all substitutions are subject to the approval by BHG's board of managers. As a result, the reacquired loans are deemed purchase credit impaired and recorded on BHG's balance sheet at the net present value of the loan's anticipated cash flows.  BHG will then initiate collection efforts and attempt to restore the reacquired loan to performing status. Substitution losses are recorded as a contra revenue account and reduce total revenues discussed above. BHG maintained a liability as of September 30,March 31, 2018 and 2017 and 2016 of $63.9$72.9 million and $39.9$52.9 million, respectively, that represents an estimate of the future inherent losses for the outstanding core portfolio that may be subject to future substitution.

BHG will maintain loans on its balance sheet for a period of time prior to sale or transfer to a purchaser. BHG also has an investment portfolio on which it earns interest and dividend income. Net interest income and fees associated with this activity amounted to $5.0$6.5 million and $13.8$4.2 million, respectively, for the three and nine months ended September 30, 2017, as compared to $4.2 millionMarch 31, 2018 and $15.5 million, respectively, for same periods in the prior year. 

March 31, 2017. 

Additionally, BHG will also refer loans to other financial institutions and, based on an agreement with the institution, earn a fee for doing so. Typically, these are loans that BHG believes would either be classified as consumer-type loans rather than commercial loans, the loans fail to meet the credit underwriting standards of BHG but another institution will accept the loans or these are loans to borrowers in certain geographic locations where BHG has elected not to do business. For the three and nine months ended September 30, 2017,March 31, 2018, BHG recognized fee income of $1.9 million and $5.8 million, respectively,$190,000 as compared to $3.5$2.1 million and $9.6 million, respectively, for the same periodsperiod in the prior year related to these activities.  

During the three and nine months ended September 30, 2017, Pinnacle Financial and Pinnacle Bank received $4.5 million and $19.4 million, respectively, in dividends in the aggregate from BHG compared to $5.0 million and $26.8 million, respectively for the three and nine months ended September 30, 2016. These dividends reduced the carrying amount of our investment in BHG while earnings from BHG increased the carrying amount of our investment in BHG. Our proportionate share of earnings from BHG are included in our consolidated tax return. Profits from intercompany transactions are eliminated. Earnings from BHG will fluctuate from period-to-period.

Included in other noninterest income are interchange and other consumer fees, gains from bank-owned life insurance, swap fees earned for the facilitation of derivative transactions for our clients, and other noninterest income items. Interchange revenues increased in the three and nine months ended September 30, 2017March 31, 2018 as a result of an increase in the number of cards being usedincreased debit and credit card transactions as compared to the comparable periodsperiod in 2016. Interchange revenues increased year-over-year,2017 resulting from both customers added through acquisition and organic growth, but were negatively impacted by the Durbin amendment which was applicable to us beginning on July 1, 2017. We estimate that the Durbin amendment negatively impacted our noninterest income by approximately $1.8$2.8 million to $2.0$3.7 million in the thirdfirst quarter of 2017.2018. Other noninterest income included changes in the cash surrender value of bank-owned life insurance which was $2.6$2.8 million and $5.1 million, respectively, for the three and nine months ended September 30, 2017March 31, 2018 compared to $955,000 and $2.6$1.1 million respectively, for the three and nine months ended September 30, 2016.March 31, 2017. The increase in earnings on these bank-owned life insurance policies resulted primarily from the additional $202.3 million of bank-owned life insurance policies with terms similar to our existing policies which were added upon acquisition of BNC. The assets that support these policies are administered by the life insurance carriers and the income we receive (i.e., increases or decreases in the cash surrender value of the policies) on these policies is dependent upon the returns the insurance carriers are able to earn on the underlying investments that support the policies. Earnings on these policies generally are not taxable. Loan swap fees are also included in other noninterest income and increased by $152,000 and decreased by $1.8 million, respectively,$243,000 when compared to the three and nine months ended September 30, 2016,March 31, 2017, as a result of manyincrease in market demand in the current rate environment. Also included in other noninterest income are fees related to SBA loan sales which were $1.1 million for the three months ended March 31, 2018 compared to $307,000 for the three months ended March 31, 2017. The growth in fees related to SBA loan sales was principally the result of our clients opting for current lower-coupon variable rate structures.acquisition of BNC, which engaged in a larger volume of these transactions than we did prior to the merger.

Total salaries and employee benefits expenses increased approximately $28.2$25.4 million and $43.5 million, respectively, for the three and nine months ended September 30, 2017March 31, 2018 compared to the same periodsperiod in 2016. The increase in salaries is2017, primarily the result of our annual merit increases that are effective on January 1 of each year as well as the overall increase in our associate base. At September 30, 2017,March 31, 2018, our associate base had expanded to 2,194.52,148.0 full-time equivalent associates as compared to 1,177.51,217.5 at September 30, 2016.March 31, 2017. At September 30, 2017,March 31, 2018, the BNC footprintCarolinas and Virginia represented approximately 947557 full-time equivalent associates. We expect salary and benefit expenses will

continue to rise as we hire more experienced bankers throughout our expanded franchise or new markets in which we might expand and add associates resulting from mergers and/or acquisitions. Moreover, as our total assets now exceed $20 billion, we also expect our compliance costs and FDIC insurance assessment expense will continue to increase.


We believe that cash and equity incentives are a valuable tool in motivating an employee base that is focused on providing our clients effective financial advice and increasing shareholder value. As a result, and unlike many other financial institutions, all of our non-commissioned associates participate in our annual cash incentive plan with a minimum targeted bonus equal to 10% of each associate's annual salary, and all of our associates participate in our equity compensation plans. Under the annual cash incentive plan, the targeted level of incentive payments requires achievement of a certain soundness threshold a revenue component and a targeted level of revenues and earnings (subject to certain adjustments). To the extent that the soundness threshold is met and revenues and earnings are above or below the targeted amount, the aggregate incentive payments are increased or decreased. Historically, we have paid between 0% and 125% of our targeted incentives. We are currently accruingFor the first quarter of 2018, we accrued incentive costs for the cash incentive plan in 2017 slightly below2018 at less than our targeted awards.

Also included in employee benefits and other expense for the quarters ended March 31, 2018 and 2017 were approximately $4.4 million and $3.5 million, respectively, of compensation expenses related to equity-based awards for restricted shares or restricted share units, including those with performance-based vesting criteria. We have not issued stock options since 2008. Under our equity incentive plans, we provide a broad-based equity incentive program for all associates. We believe that equity incentives provide a vehicle for all associates to become meaningful shareholders of Pinnacle Financial over an extended period of time and create a shareholder-centric culture throughout our organization. We expect thatOur compensation expense associated with equity awards for the remainder of 2017 will continue to increasequarter ended March 31, 2018 increased when compared to comparable periods in 2016the quarter ended March 31, 2017 as a result of the additional associates we have hired since March 31, 2017, primarily in connection with our acquisition of BNC. We expect our compensation expense associated with equity awards to continue to increase in 2018 when compared to 2017 andas a result of our intention to hire additional experienced financial advisors throughoutduring the remainder of 2017, as well as those additional associates obtained2018. Employee benefits and other expenses include costs associated with the acquisition of BNC.our 401k plan, health insurance, and payroll taxes.

Equipment and occupancy expenses for the three and nine months ended September 30, 2017,March 31, 2018 increased $7.2$8.1 million and $11.1 million, respectively, as compared to the same periodsperiod in the prior year due to our acquisitionsBNC merger and two new locations opened in our Tennessee markets in the latter part of 2017. We intend to expand our footprint by one location in each of the Knoxville, Chattanooga, and Memphis MSAs annually. In future periods, any new facilities, either branches or operational offices willthese expansions may lead to higher equipment and occupancy expenses as well as related increases in salaries and benefits expense. There are no current plans to expand our branch distribution in the Carolinas and Virginia.

Marketing and business development expense for the three and nine months ended September 30, 2017March 31, 2018 was $2.2 million and $6.2 million, respectively, compared to $1.3 million and $4.2$1.9 million for the three and nine months ended September 30, 2016.March 31, 2017. The primary source of the increase in 2018 as compared to 2017 is related to our advertisingmerger with BNC and banking sponsorships with a professional sports franchise in Memphis, which was entered into late in the third quarter of 2016, as well asassociated marketing and business development expenses for the increase associated with our acquisition of BNC.expanded footprint.

Intangible amortization expense was $3.1$2.7 million and $5.7 million, respectively, for the three and nine months ended September 30, 2017March 31, 2018 compared to $1.4$1.2 million and $3.1 million, respectively, for the same periodsperiod in 2016.2017.

These increases are attributable2017. This increase is due to a variety of factors includingand includes increases in FDIC insurance premiums of $2.3 million as well as increases in fees related to our credit card reward programs, increases in audit and consulting fees and increased directorsdirectors' fees regulatory and audit fees.in the three months ended March 31, 2018 when compared to the three months ended March 31, 2017.

Our efficiency ratio (ratio of noninterest expense to the sum of net interest income and noninterest income) was 50.8% and 51.1%49.7% for the three and nine months ended September 30, 2017March 31, 2018 compared to 53.7% and 53.3%52.1% for the three and nine months ended September 30, 2016.March 31, 2017.

Income Taxes. During the three and nine months ended September 30, 2017,March 31, 2018, Pinnacle Financial recorded income tax expense of $35.1$19.6 million and $68.8 million, respectively, compared to $16.3$13.8 million and $45.9 million, respectively, for the three and nine months ended September 30, 2016.March 31, 2017.

The composition of our loan portfolio at September 30, 2017 when comparedhas changed due to December 31, 2016 was impacted by our acquisition ofmerger with BNC, which had more of a commercial real estate focus, including construction, than we did in our legacy Tennessee markets. As we intend to focus on growth of the commercial and industrial segment in our expanded footprint, we continue to believe our commercial and industrial portfolio will again become a more substantial portion of our total loan portfolio. The commercial real estate – mortgage category includes owner-occupied commercial real estate loans.  At March 31, 2018, approximately 35.7% of the outstanding principal balance of our commercial real estate - mortgage loans which we believe arewas secured by owner-occupied commercial real estate properties. Owner-occupied commercial real estate is similar in many ways to our commercial and industrial lending in that these loans are generally made to businesses on the basis of the cash flows of the business rather than on the valuation of the real estate. At September 30, 2017, approximately 37.7% of the outstanding principal balance of our commercial real estate mortgage loans was secured by owner-occupied properties compared to 42.4% at December 31, 2016. Growth in the construction and land development loan segment reflects the development growth of the local economies in which we participateoperate and is diversified between commercial, residential and land.

Pinnacle Financial monitors two ratios regarding construction and commercial real estate lending as part of its concentration management processes.  Both ratios are calculated by dividing certain types of loan balances for each of the two categories by Pinnacle Bank’s total risk-based capital.   At March 31, 2018 and December 31, 2017, Pinnacle Bank’s construction and land development loans as a percentage of total risk-based capital were 96.1% and 89.4%, respectively. Non-owner occupied commercial real estate and multifamily loans (including construction and land development loans) as a percentage of total risk-based capital were 306.2% and 297.1% as of March 31, 2018 and December 31, 2017, respectively. Banking regulations have established guidelines for the construction ratio of less than 100% of total risk-based capital and for the non-owner occupied ratio of less than 300% of total risk-based capital. When a bank’s ratios are in excess of one or both of these guidelines, banking regulations generally require an increased level of monitoring in these lending areas by bank management.  At March 31, 2018 we slightly exceeded the 300% guideline and have established what we believe to be appropriate controls to monitor our lending in this area as we aim to reduce the level of these loans to below the 300% threshold in the second half of 2018.

The following table classifies our fixed and variable rate loans at September 30, 2017March 31, 2018 according to contractual maturities of (1) one year or less, (2) after one year through five years, and (3) after five years.  The table also classifies our variable rate loans pursuant to the contractual repricing dates of the underlying loans (dollars in thousands):

(*) Daily floating rate loans are tied to Pinnacle Bank's prime lending rate or a national interest rate index with the underlying loan rates changing in relation to changes in these indexes. Included in variable rate loans are $370.0$168.5 million of loans which are currently priced at their contractual floors with a weighted average rate of 4.95%5.32%. The weighted average contractual rate on these loans is 4.25%4.71%. As a result, interest income on these loans will not change until the contractual rate on the underlying loan exceeds the interest rate floor.

Potential Problem Loans. Potential problem loans, which are not included in nonperforming assets, amounted to approximately $148.7$158.1 million, or 1.2%1.0% of total loans at September 30, 2017,March 31, 2018, compared to $114.6$164.0 million, or 1.4%1.1% of total loans at December 31, 2016.2017. 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 serious 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 nonaccrual loans and substandard troubled debt restructurings. Troubled debt restructurings are not included in potential problem loans. Approximately $3.9$8.3 million of potential problem loans were past due at least 30 days but less than 90 days as of September 30, 2017.March 31, 2018.

Nonperforming Assets and Troubled Debt Restructurings. At September 30, 2017,March 31, 2018, we had $78.1$94.7 million in nonperforming assets compared to $33.7$85.5 million at December 31, 2016.2017. Included in nonperforming assets were $53.4$70.2 million in nonaccrual loans and $24.7$24.5 million in OREO and other nonperforming assets at September 30, 2017March 31, 2018 and $27.6$57.5 million in nonaccrual loans and $6.1$28.0 million in OREO and other nonperforming assets at December 31, 2016.  The increase in nonperforming assets at September 30, 2017 is primarily a result of the acquisition of such assets related to our BNC Merger.2017. At September 30, 2017March 31, 2018 and December 31, 2016,2017, there were $15.2$6.1 million and $15.0$6.6 million, respectively, of troubled debt restructurings, all of which were accruing as of the restructured date and remain on accrual status but are considered impaired loans pursuant to U.S. GAAP.
 
Allowance for Loan Losses (allowance). We maintain the allowance at a level that our management deems appropriate to adequately cover the probable losses inherent in the loan portfolio.  As of September 30, 2017March 31, 2018 and December 31, 2016,2017, our allowance for loan losses was approximately $65.2$70.2 million and $59.0$67.2 million, respectively, which our management deemed to be adequate at each of the respective dates. Our allowance for loan losses is adjusted to an amount deemedthat our management deems appropriate to adequately cover the probable losses in the loan portfolio based on our allowance for loan loss methodology. Our allowance for loan losses as a percentage of loans decreasedremained unchanged at March 31, 2018 from 0.70% at December 31, 2016 to2017 at 0.43% at September 30, 2017, primarily attributable to the BNC portfolio being recorded at fair value upon acquisition.. As a result of our acquired loan portfolios being recorded at fair value upon acquisition, no allowance for loan losses is assigned to purchased loans as of the date of acquisition. However, an allowance for loan losses is recorded for purchased loans that have experienced credit deterioration subsequent to acquisition or increases in balances outstanding.


As of September 30, 2017,March 31, 2018, net loans included a remaining net fair value discount of $182.4$148.9 million. For the ninethree months ended September 30, 2017,March 31, 2018, the net fair value discount changed as follows:

Management assesses the adequacy of the allowance prior to the end of each calendar quarter. This assessment includes procedures to estimate the allowance and test the adequacy and appropriateness of the resulting balance.  The level of the allowance is based upon management's evaluation of the loan portfolios, past loan loss experience, known and inherent risks in the portfolio, the views of Pinnacle Bank's regulators, adverse situations that may affect the borrower's ability to repay (including the timing of future payments), the estimated value of any underlying collateral, composition of the loan portfolio, economic conditions, industry and peer bank loan quality indications and other pertinent factors. This evaluation is inherently subjective as it requires material estimates including the amounts and timing of future cash flows expected to be received on impaired loans that may be susceptible to significant change.  For further discussion regarding our allowance for loan losses, refer to Critical Accounting Estimates above.
Based upon our evaluation of the loan portfolio, we believe the allowance for loan losses to be adequate to absorb our estimate of inherent losses existing in the loan portfolio at September 30, 2017.March 31, 2018. While our policies and procedures used to estimate the allowance for loan losses as well as the resultant provision for loan losses charged to operations are considered adequate by management, they are necessarily approximate and imprecise. There are factors beyond our control, such as conditions in the local and national economy, local real estate market or a particular industry or borrower which may negatively impact, materially, our asset quality and the adequacy of our allowance for loan losses and, thus, the resulting provision for loan losses.

Investments.  Our investment portfolio, consisting primarily of Federal agency bonds, mortgage-backed securities, and state and municipal securities amounted to $2.90$2.98 billion and $1.32$2.54 billion at September 30, 2017March 31, 2018 and December 31, 2016,2017, respectively. Our investment portfolio serves many purposes including serving as a stable source of income, as collateral for public funds deposits and as a potential liquidity source. A summary of our investment portfolio at September 30, 2017March 31, 2018 and December 31, 20162017 follows:

Deposits and Other Borrowings.  We had approximately $15.79$16.50 billion of deposits at September 30, 2017March 31, 2018 compared to $8.76$16.45 billion at December 31, 2016. Total deposits acquired from BNC on June 16, 2017 were $6.21 billion.2017. Our deposits consist of noninterest and interest-bearing demand accounts, savings accounts, money market accounts and time deposits. Additionally, we entered into agreements with certain customers to sell certain securities under agreements to repurchase the security the following day. These

agreements (which are typically associated with comprehensive treasury management programs for our clients and provide them with short-term returns for their excess funds) amounted to $129.6$131.9 million at September 30, 2017March 31, 2018 and $85.7$135.3 million at December 31, 2016.2017. Additionally, at September 30, 2017March 31, 2018 and December 31, 2016,2017, Pinnacle Bank had borrowed $1.62$1.98 billion and $406.3 million,$1.32 billion, respectively, in advances from the Federal Home Loan Bank of Cincinnati (FHLB). At September 30, 2017,March 31, 2018, Pinnacle Bank also had approximately $2.44$4.1 billion in additional availability with the FHLB; however, incremental borrowings are made in a formal request by Pinnacle Bank and the subsequent approval by the FHLB.


Generally, we have classified our funding base as either core funding or non-core funding.  Core funding consists of all deposits other than time deposits issuedas shown in denominations greater than $250,000. All other funding is deemed to be non-core.the table below. The following table represents the balances of our deposits and other funding and the percentage of each type to the total at September 30, 2017March 31, 2018 and December 31, 20162017 (dollars in thousands):

As noted in the table above, our core funding as a percentage of total funding decreased from 77.6% at December 31, 2017 to 74.6% at March 31, 2018, primarily as a result of our increased FHLB advances and increased levels of brokered deposits. When wholesale funding is necessary to complement the company's core deposit base, management determines which source is best suited to address both liquidity risk management and interest rate risk management objectives.  We increased our exposure to brokered deposits in the first quarter of 2018 as a measure to diversify wholesale funding sources. Our Asset Liability Management Policy institutes limitations on overall wholesale funding reliance and on brokered deposit exposure specifically. Both our overall reliance on wholesale funding and exposure to brokered deposits were within those policy limitations as of March 31, 2018.

Our funding policies impose limits on the amount of non-core funding we can utilize.utilize based on the non-core funding dependency ratio which is calculated pursuant to regulatory guidelines. Periodically, we may exceed our policy limitations, at which time management will develop plans to bring our funding sources back into compliance with our core funding ratios.  At September 30, 2017March 31, 2018 and December 31, 2016,2017, we were in compliance with our core funding policies. As noted in the table above, our core funding as a percentage of total funding decreased from 81.6% at December 31, 2016 to 74.3% at September 30, 2017, primarily as a result of our increased FHLB advances and increased levels of brokered deposits and brokered time deposits resulting from among other things, the impact of our completed acquisitions. FHLB advances increased between December 31, 2016 and September 30, 2017 by $1.2 billion. Our use of FHLB advances will likely remain elevated as we continue to fund significant organic growth and rebalance the composition of BNC's deposit portfolio primarily focused on reducing the reliance on higher cost brokered time deposits.

Growing our core deposit base particularly in our markets is a key strategic objective of our firm. We have numerous commercial and affluent consumer depositorsOur current growth plans contemplate that maintain significant balances in their transaction and money market accounts. These deposits are subject to significant fluctuationswe may increase our non-core funding amounts from time to time forcurrent levels, but we do not currently anticipate that such purposes as distributions to owners, taxes, business acquisitions, etc. As a result,increases will exceed our core funding ratios may also fluctuate meaningfully based on these factors.internal policies.



The amount of time deposits as of September 30, 2017March 31, 2018 amounted to $2.5$2.57 billion.  The following table shows our time deposits in denominations of $250,000$100,000 and less and in denominations greater than $250,000$100,000 by category based on time remaining until maturity and the weighted average rate for each category as of September 30, 2017March 31, 2018 (in thousands):

Following the Mergermerger with BNC and as a result of that merger, Pinnacle Financial's total assets were in excess of $15.0 billion as a result of the acquisition of BNC, which caused the subordinated debentures Pinnacle Financial and BNC issued to cease to qualify as Tier 1 capital under applicable banking regulations. Though these securities no longer qualify as Tier 1 capital, Pinnacle Financial believes these subordinated debentures continue to qualify as Tier 2 capital.
 
Capital Resources. At September 30, 2017March 31, 2018 and December 31, 2016,2017, our shareholders' equity amounted to $3.67$3.75 billion and $1.50$3.71 billion, respectively, an increase of approximately $2.17 billion.  Approximately $192.2 million of this increase is attributable to our issuance of common equity in the first quarter of 2017 to support our future growth. Additionally, $1.85 billion is attributable to our acquisition of BNC.$41.4 million. The remaining increase is attributable to net income, equity compensation and changes in our other comprehensive income.

Dividends. Pursuant to Tennessee banking law, our bank may not, without the prior consent of the TDFI, pay any dividends to us in a calendar year in excess of the total of our bank's retained net profits for that year plus the retained net profits for the preceding two years, which was $466.8 million at September 30, 2017.March 31, 2018.  During the three and nine months ended September 30, 2017,March 31, 2018, our bank paid dividends of $22.4$25.1 million and $38.1 million, respectively, to us which is within the limits allowed by the TDFI.

During the three and nine months ended September 30, 2017,March 31, 2018, we paid $10.9$11.0 million and $25.0 million, respectively, in dividends to our common shareholders. On OctoberApril 17, 2017,2018, our board of directors declared a $0.14 quarterly cash dividend to common shareholders which should approximate $10.9$11.0 million in aggregate dividend payments that will be paid on November 24, 2017May 25, 2018 to common shareholders of record as of the close of business on November 3, 2017.May 4, 2018. The amount and timing of all future dividend payments, if any, is subject to board discretion and will depend on our earnings, capital position, financial condition and other factors, including regulatory capital requirements, as they become known to us.

Market and Liquidity Risk Management

Our objective is to manage assets and liabilities to provide a satisfactory, consistent level of profitability within the framework of established liquidity, loan, investment, borrowing, and capital policies. Our Asset Liability Management Committee (ALCO) is charged with the responsibility of monitoring these policies, which are designed to ensure acceptable composition of asset/liability mix. Two critical areas of focus for ALCO are interest rate sensitivity and liquidity risk management.

Interest Rate Sensitivity.  In the normal course of business, we are exposed to market risk arising from fluctuations in interest rates.  ALCO measures and evaluates the interest rate risk so that we can meet customer demands for various types of loans and deposits.  ALCO determines the most appropriate amounts of on-balance sheet and off-balance sheet items.  Measurements which we use to help us manage interest rate sensitivity include an earnings simulation model and an economic value of equity (EVE) model. 

Our interest rate sensitivity modeling incorporates a number of assumptions for both earnings simulation and EVE, including loan and deposit re-pricing characteristics, the rate of loan prepayments, etc. ALCO periodically reviews these assumptions for accuracy based on historical data and future expectations. Our ALCO policy requires that the base scenario assume rates remain flat and is the scenario to which all others are compared in order to measure the change in net interest income and EVE. Policy limits are applied to the results of certain modeling scenarios. While the primary policy scenarios focus is on a twelve month time frame for the earnings simulations model, longer time horizons are also modeled. All policy scenarios assume a static volume forecast where the balance sheet is held constant, although other scenarios are modeled.
 

Earnings simulation model. We believe interest rate risk is best measured by our earnings simulation modeling. Earning assets, interest-bearing liabilities and off-balance sheet financial instruments are combined with forecasts of interest rates for the next 12 months and are combined with other factors in order to produce various earnings simulations.simulations over that same 12-month period. To limit interest rate risk, we have policy guidelines for our earnings at risk which seek to limit the variance of net interest income in both gradual and instantaneous changes to interest rates. For instantaneous upward changes up or down in rates from management's flat interest rate forecast over the next twelve months, management establishes policy limits in the decline in net interest income, assuming a flatstatic balance sheet, for the following scenarios:changes are predicted:

-10.0% for
Estimated % Change in Net Interest Income Over 12 Months
March 31, 2018
Instantaneous Rate Change
100 bps increase5.3%
200 bps increase9.7%

While an instantaneous and severe shift in interest rates was used in this analysis to provide an estimate of exposure under these scenarios, we believe that a gradual changeshift in interest rates would have a more modest impact. Further, the earnings simulation model does not take into account factors such as future balance sheet growth, changes in product mix, changes in yield curve relationships, and changing product spreads that could mitigate the adverse impact of 400 basis points; -20.0% instantaneous change of 400 basis points
-7.5 % for gradual change of 300 basis points; -15.0% instantaneous change of 300 basis points
-5.0% for gradual change of 200 basis points; -10.0% instantaneous change of 200 basis points
-2.5% for gradual change of 100 basis points; -5.0% instantaneous change of 100 basis points

changes in interest rates.

At September 30, 2017,March 31, 2018, our earnings simulation model indicated we were in compliance with our policies for both the gradual and instantaneous interest rate changes. However, our policies provide that during certain interest rate cycles, the down basis point rate changes may not be particularly significant given the current level and slope of the yield curve.  Accordingly, we have currently suspended the calculation of the down rate scenarios for earnings simulation measurement forwhich we model as required by our board approved Asset Liability Policy. The board has suspended the requirement to model down 300 and down 400 scenarios.bps scenarios while 10 year maturity Treasury rates are below 3.0%, which was the case as of March 31, 2018.
 
Economic value of equity modelOurWhile earnings simulation modeling attempts to determine the impact of a changing rate environment to our net interest income, our EVE model measures estimated changes to the extent that estimated economic values of our assets, liabilities and off-balance sheet items will change as a result of interest rate changes. Economic values are determined by discounting expected cash flows from assets, liabilities and off-balance sheet items, which establishes a base case EVE. To help limit interestWe then shock rates as prescribed by our Asset Liability Policy and measure the sensitivity in EVE values for each of those shocked rate risk, we have stated policy guidelinesscenarios versus the base case. The Asset Liability Policy sets limits for those sensitivities. At March 31, 2018, our EVE modeling indicates the following changes in EVE due to instantaneous upward changes in rates:
March 31, 2018
Instantaneous Rate Change
100 bps increase(1.7%)
200 bps increase(4.9%)

While an instantaneous basis point changeand severe shift in interest rates was used in the following scenarios:

+/- 400 basis point changethis analysis to provide an estimate of exposure under these scenarios, we believe that a gradual shift in interest rates would have a more modest impact. Since EVE shall not decrease by more than 40 percent
+/- 300 basis pointmeasures the discounted present value of cash flows over the estimated lives of instruments, the change in interest rates, EVE shalldoes not decrease by more than 30 percent
+/- 200 basis point changedirectly correlate to the degree that earnings would be impacted over a shorter time horizon (i.e., the current year). Further, EVE does not take into account factors such as future balance sheet growth, changes in product mix, changes in yield curve relationships, and changing product spreads that could mitigate the adverse impact of changes in interest rates, EVE shall not decrease by more than 20 percent
+/- 100 basis point change in interest rates, EVE shall not decrease by more than 10 percentrates.

At September 30, 2017,March 31, 2018, our EVE model indicated we were in compliance with our policies for the scenarios noted above.  However, our policies provide that during certainall interest rate cycles, the down basis point rate changes may not be particularly significant given the current level and slope of the yield curve.  Accordingly, we have currently suspended the calculation of the down rate scenarios for EVE measurement forwhich we model as required by our board approved Asset Liability Policy. The board has suspended the requirement to model down 300 bps and down 400 scenarios.bps scenarios while 10 year maturity Treasury rates are below 3.0%, which was the case as of March 31, 2018.

Most likely earnings simulation models.We also analyze a most-likely earnings simulation scenario that projects the expected change in rates based on a forward yield curve adopted by management using expected balance sheet volumes forecasted by management.  Separate growth assumptions are developed for loans, investments, deposits, etc.  Other interest rate scenarios analyzed by management may include delayed rate shocks, yield curve steepening or flattening, or other variations in rate movements to further analyze or stress our balance sheet under various interest rate scenarios. Each scenario is evaluated by management and weighted to determine the most likely result. These processes assist management to better anticipate the financial results of the Company and, as a result, management may determine the need to invest in other operating strategies and tactics which might enhance results or better position the firm's balance sheet to reduce interest rate risk going forward.



Each of the above analyses may not, on its own, be an accurate indicator of how our net interest income will be affected by changes in interest rates.  Income associated with interest-earning assets and costs associated with interest-bearing liabilities may not be affected uniformly by changes in interest rates.  In addition, the magnitude and duration of changes in interest rates may have a significant impact on net interest income.  For example, although certain assets and liabilities may have similar maturities or periods of repricing, they may react in different degrees to changes in market interest rates.  Interest rates on certain types of assets and liabilities fluctuate in advance of changes in general market rates, while interest rates on other types may lag behind changes in general market rates.  In addition, certain assets, such as adjustable rate mortgage loans, have features (generally referred to as interest rate caps and floors) which limit changes in interest rates.  Prepayment and early withdrawal levels also could deviate significantly from those assumed in calculating the maturity of certain instruments. The ability of many borrowers to service their debts also may decrease during periods of rising interest rates.  ALCO reviews each of the above interest rate sensitivity analyses along with several different interest rate scenarios as part of its responsibility to provide a satisfactory, consistent level of profitability within the framework of established liquidity, loan, investment, borrowing, and capital policies.

We may also use derivativeManagement's model governance, model implementation and model validation processes and controls are subject to review in our regulatory examinations to ensure they are in compliance with the most recent regulatory guidelines and consistent with the best practices of our industry. Management utilizes a respected, sophisticated third party asset liability modeling software to help ensure implementation of management's assumptions into the model are processed as intended in a robust manner. That said, there are numerous assumptions regarding financial instrument behavior that are integrated into the model. The assumptions are formulated by combining observations gleaned from our historical studies of financial instruments and our best estimations of how, if at all, these instruments may behave in the future given changes in economic conditions, technology, etc. These assumptions may prove to improvebe inaccurate. Additionally, given the balance between interest-sensitive assets and interest-sensitive liabilities as one toollarge number of assumptions built into firm's asset liability modeling software, it is difficult at best to managecompare our interest rate sensitivity while continuingresults to meet the credit and deposit needs of our customers. We may also enter into interest rate swaps to facilitate customer transactions and meet their financing needs.  These swaps qualify as derivatives, even though they are not designated as hedging instruments.

Based on information gathered from these various modeling scenarios management believes that at September 30, 2017, our balance sheet would likely be modestly asset sensitive.other firms.

ALCO may determine that Pinnacle Financial should over time become more or less asset or liability sensitive depending on the underlying balance sheet circumstances and the firm's conclusions as to anticipated interest rate fluctuations in future periods.  At present, ALCO has determined that its "most likely" rate scenario considers onetwo additional increaseincreases in short-term interest rates in 2017.2018.  Our "most likely" rate forecast has been basicallylargely consistent for severalover recent quarters and is based primarily on information we acquire from a service which includes a consensus forecast of numerous benchmarks. Over the last several quarters we have taken steps to make our balance sheet more asset sensitive, which has favorably impacted us in the current rising rate environment and should continue to positively impact our results with additional rate increases unless we are unable to hold our funding costs at levels that don't eliminate the positive impact to interest income of these rising rates. However, BNC’s balance sheet was less asset sensitive which neutralizes some, if not most, of the impact of those steps, nonetheless, we have implemented andWe may implement additional actions designed to achieve our desired sensitivity position.

We may also use derivative financial instruments to improve the balance between interest-sensitive assets and interest-sensitive liabilities as one tool to manage our interest rate sensitivity, including that inherent in our mortgage lending program, while continuing to meet the credit and deposit needs of our customers. We may also enter into interest rate swaps to facilitate customer transactions and meet their financing needs.  These swaps qualify as derivatives, even though they are not designated as hedging instruments.

Liquidity Risk Management.  The purpose of liquidity risk management is to ensure that there are sufficient cash flows to satisfy loan demand, deposit withdrawals, and our other needs.  Traditional sources of liquidity for a bank include asset maturities and growth in core deposits.  A bank may achieve its desired liquidity objectives from the management of its assets and liabilities and by internally generated funding through its operations.  Funds invested in marketable instruments that can be readily sold and the continuous maturing of other earning assets are sources of liquidity from an asset perspective.  The liability base provides sources of liquidity through attraction of increased deposits and borrowing funds from various other institutions. Maintaining increased levels of liquid assets on our balance sheet, in the form of readily marketable investment securities or other highly liquid assets, could negatively impact our profitability as the interest we earn on these assets is less than that we earn on other earning assets like loans.

To assist in determining the adequacy of our liquidity, we perform a variety of liquidity stress tests including idiosyncratic, systemic and combined scenarios for both moderate and severe events. Liquidity is defined as the ability to convert assets into cash or cash equivalents without significant loss and to raise additional funds by increasing liabilities. Liquidity management involves maintaining our ability to meet the daily cash flow requirements of our customers, both depositors and borrowers. We seek to  maintain ona sufficiently liquid asset balance sheet liquidity consisting of cash and unpledged securities at a level we believe will allow usto ensure our ability to meet our obligations. The sizeamount of the appropriate minimum liquid asset balance is determined through severe liquidity stress testing.testing as measured by our liquidity coverage ratio calculation. At September 30, 2017,March 31, 2018, we were in compliance with our liquidity stress testing policy requirements.coverage ratio.

Changes in interest rates also affect our liquidity position. We currently price deposits in response to market rates, and our management intends to continue this policy. If deposits are not priced in response to market rates, a loss of deposits could occur which would negatively affect our liquidity position. Alternatively, we may have to raise the rates we pay on deposits which would negatively impact our net interest income.

Scheduled loan payments are a relatively stable source of funds, but loan payoffs and deposit flows fluctuate significantly, being influenced by interest rates, general economic conditions competition and the specific needs of our customers.competition. Additionally, debt security investments are subject to prepayment and call provisions that could accelerate their payoff prior to stated maturity. We attempt to price our deposit products to

meet our asset/liability objectives consistent with local market conditions. Our ALCO is responsible for monitoring our ongoing liquidity needs. Our regulators also monitor our liquidity and capital resources on a periodic basis and may require that we increase our levels of liquidity or the mixture of our liquidity components which could negatively impact our results of operations.basis.

In addition, our bank is a member of the FHLB Cincinnati.  As a result, our bank receives advances from the FHLB Cincinnati, pursuant to the terms of various borrowing agreements, which assist it in the funding of its home mortgage and commercial real estate loan portfolios. Under the borrowing agreements with the FHLB Cincinnati, our bank has pledged certain qualifying residential mortgage loans and, pursuant to a blanket lien, all qualifying commercial mortgage loans as collateral. As such, Pinnacle Bank may use the FHLB Cincinnati as a source of liquidity depending on its ALCO strategies. Additionally, we may pledge additional qualifying assets or reduce the amount of pledged assets with the FHLB Cincinnati to increase or decrease our borrowing capacity with the FHLB Cincinnati. At September 30, 2017,March 31, 2018, we believe we had an estimated $2.44$4.1 billion in additional borrowing capacity with the FHLB Cincinnati.  However, incremental borrowings are made via a formal request by Pinnacle Bank and the subsequent approval by the FHLB Cincinnati. At September 30, 2017,March 31, 2018, our bank had received advances from the FHLB Cincinnati totaling $1.62$1.98 billion. Pinnacle Financial has recognized a discount on FHLB Cincinnati advances in conjunction with its acquisitions within its Tennessee markets. The remaining discount was $33,000 at September 30, 2017. At September 30, 2017,March 31, 2018, the scheduled maturities of the Pinnacle Bank's FHLB Cincinnati advances and interest rates are as follows (in thousands):

Pinnacle Bank also has accommodations with upstream correspondent banks available for unsecured short-term advances which aggregate $160.0$170.0 million.  These accommodations have various covenants related to their term and availability, and in most cases must be repaid within a month of borrowing. We had no outstanding borrowings at September 30, 2017March 31, 2018 under these agreements. Our bank also has approximately $3.08$2.84 billion in available Federal Reserve discount window lines of credit.

At September 30, 2017,March 31, 2018, excluding reciprocating time deposits issued through the Promontory Network, we had $1.38$1.28 billion of brokered deposits. Historically, we have issued brokered depositscertificates of deposit through several different firmsbrokerage houses based on competitive bid.  Through the BNC acquisition, we increased our levels of non-reciprocal insured cash sweep deposits under various multi-year agreements. Typically, the brokeredthese funds have been for varying maturities of up to fourtwo years and were issued at rates which were competitive to rates that we would be required to pay to attract similar deposits within our local markets as well as rates for FHLB Cincinnati advances of similar maturities. Although we consider these deposits to be a ready source of liquidity under current market conditions, we anticipate that these deposits will continue to represent a small percentage of our total funding in 2017 as we seek to continue maintaining a higher level of core deposits.

Industry regulators have defined additional liquidity guidelines, through the issuance of the Basel III Liquidity Coverage Ratio (LCR) and the Modified LCR, for banking institutions greater than $250 billion in assets, and $50 billion in assets respectively, in the United States. These regulatory guidelines became effective January 2015 with phase in over subsequent years and will require these large institutions to follow prescriptive guidance in determining an absolute level of a high quality liquid asset (HQLA) buffer that must be maintained on their balance sheets in order to withstand a potential liquidity crisis event. Although Pinnacle Financial follows the principles outlined in the Interagency Policy Statement on Liquidity Risk Management, issued March 2010, to determine its HQLA buffer, Pinnacle Financial is not currently subject to these regulations. However, these formulas could eventually be imposed on smaller banks, such as Pinnacle Bank, and require an increase in the absolute level of liquidity on our balance sheet. Consequently, thissheet, which could result in lower net interest margins for us in future periods.

At September 30, 2017,March 31, 2018, we had no significant commitments for capital expenditures, althoughexpenditures. However, we intend to construct additional retail locationsexpand our footprint by one location in each of the Knoxville, Chattanooga, and Memphis MSAs annually. In future periods, these expansions may lead to higher equipment and occupancy expenses as well as related increases in salaries and benefits expense. There are no current plans to expand our various markets. We will also incur additional capital expenditures as we develop an infrastructure to incorporate BNC into our network. Our management believes that we have adequate liquidity to meet all known contractual obligationsbranch distribution in the Carolinas and unfunded commitments, including loan commitments and reasonable borrower, depositor, and creditor requirements over the next twelve months.Virginia.

Off-Balance Sheet Arrangements.  At September 30, 2017,March 31, 2018, we had outstanding standby letters of credit of $137.3$150.9 million and unfunded loan commitments outstanding of $5.2$5.77 billion. Because these commitments generally have fixed expiration dates and many will expire without being drawn upon, the total commitment level does not necessarily represent future cash requirements. If needed to

fund these outstanding commitments, Pinnacle Bank has the ability to liquidate Federal funds sold or on a short-term basis to borrow and purchase Federal funds from other financial institutions.

Impact of Inflation

The consolidated financial statements and related consolidated financial data presented herein have been prepared in accordance with U.S. GAAP and practices within the banking industry which require the measurement of financial position and operating results in terms of historical dollars without considering the changes in the relative purchasing power of money over time due to inflation. Unlike most industrial companies, virtually all the assets and liabilities of a financial institution are monetary in nature. As a result, interest rates have a more significant impact on a financial institution's performance than the effects of general levels of inflation.

RecentRecently Adopted Accounting Pronouncements

Except as set forth below, there are currently no new accounting standards that have been issued that will have a significant impact on the Company's financial position, results of operations or cash flows upon adoption that were not disclosed in the Company's most recent Annual Report on Form 10-K.

In August 2017, the FASB issued Accounting Standards Update No. 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities. The amendments in this ASU makesmake more financial and non-financial hedging strategies eligible for hedge accounting. It also amends the presentation and disclosure requirements and changes how companies assess effectiveness. The amendments will be effective for the Company for interim and annual periods beginning after December 15, 2018. Early2018, with early adoption is permitted. Pinnacle Financial is currently evaluatingentered into two derivative contracts, one in the impactfirst quarter of 2018 and the new guidance on its consolidated financial statements.second in the second quarter of 2018, under early adoption of this standard as noted in Note 9. Derivative Instruments herein.

In March 2017, the FASB issued Accounting Standards UpdateNo. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendment in this ASU shortens the amortization period for certain callable debt securities held at a premium to the earliest call date. The amendment does not require an

accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those periods. Early adoption is permitted with modified retrospective application. Pinnacle Financial is currently evaluating the impact of the new guidance on its consolidated financial statements.

In January 2017, the FASB issued Accounting Standards UpdateNo. 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairmentelected to simplify how an 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. Pinnacle Financial is currently evaluating the impact of the new guidance on its consolidated financial statements.

In January 2017, the FASB issued Accounting Standards Update2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The amendment inearly adopt this ASU clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) or assets or businesses. The amendments are effective for fiscal years beginning after December 15, 2017, including interim periods within those periods. Pinnacle Financial is currently evaluating the impact of the new guidance on its consolidated financial statements.

In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases guidance requiring the recognitionstandard in the statementfirst quarter of financial position of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous U.S. GAAP. The guidance requires that a lessee should recognize lease assets and lease liabilities as compared2018 with no material impact to previous U.S. GAAP that did not require lease assets and lease liabilities to be recognized for most leases. The guidance becomes effective for us on January 1, 2019. In September 2017, the FASB issued Accounting Standards Update 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842), which provides additional implementation guidance on the previously issued ASU 2016-02. Pinnacle Financial is currently evaluating the impact on its consolidated financial statements.
In June 2016, the FASB issued Accounting Standards Update 2016-13Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments (the ASU), which introduces the current expected credit losses methodology. Among other things, the ASU requires the measurement of all expected credit losses for financial assets, including loans and available-for-sale 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 loan's entire life. The ASU also requires the allowance for credit losses for purchased financial assets with credit deterioration since origination 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 credit loss 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.

In August 2016, the FASB issued  Accounting Standards Update 2016-15, Statement of Cash Flows (Topic 230), intended to reduce the diversity in practice around how certain transactions are classified within the statement of cash flows. The guidance is effective for public companies for annual periods beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted with retrospective application. Pinnacle Financial adopted this standard in the first quarter of 2018 with no material impact to its financial statements, with the exception of dividends received from our equity method investments which were reclassified from cash flow from investments to operating cash flow.

In January 2016, the FASB issued Accounting Standards Update 2016-01 Financial Instruments – Overall (Subtopic 825-10) which, among other things, (i) requires equity investments, excluding those accounted for under the equity method or that result in consolidation, to be measured at fair value with changes in fair value recognized in net income, (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that is currently evaluatingrequired to be disclosed for financial instruments measured at amortized cost on the impactbalance sheet, (iv) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (v) requires an entity to present separately in other comprehensive income the portion of the new guidancetotal change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on its consolidatedthe balance sheet or the accompanying notes to the financial statements and (viii) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity's other deferred tax assets. ASU 2016-01 became effective for Pinnacle Financial in the first quarter of 2018 and did not have a material impact on our financial statements. See Note 10. Fair Value of Financial Instruments for disclosure of the fair value of financial instruments based on an exit price notion as required by ASU 2016-01.

In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606),(Topic 606) the ASU developed as a joint project with the International Accounting Standards Board to remove inconsistencies in revenue requirements and provide a more robust framework for addressing revenue issues. The ASU's core principle is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued  Accounting Standards Update 2015-14, which deferred the effective date by one year (i.e., interim and annual reporting periods beginning after December 15, 2017). Early adoption is permitted, but not before the original effective date (i.e., interim and annual reporting periods beginning after December 15, 2016). The ASU may

be adopted using either a modified retrospective method or a full retrospective method. Pinnacle Financial intends to adoptadopted the ASU during the first quarter of 2018, as required, using a modified retrospective approach. The majority of Pinnacle Financial's preliminary analysis suggestsrevenue stream is generated from interest income on loans and deposits, which are outside the scope of Topic 606. Pinnacle Financial’s sources of income that fall within the scope of Topic 606 include service charges on deposits, investment services, insurance sales commissions, trust fees, interchange fees and gains and losses on sales of other real estate, all of which are presented within noninterest income. Pinnacle Financial has evaluated the effect of Topic 606 on these fee-based income streams and concluded that adoption of the standard did not materially impact its financial statements. The following is a summary of the implementation considerations for the revenue streams that fall within the scope of Topic 606:

Service charges on deposits, investment services, trust fees and interchange fees — Fees from these services are either transaction based, for which the performance obligations are satisfied when the individual transaction is processed, or set periodic service charges, for which the performance obligations are satisfied over the period the service is provided. Transaction based fees are recognized at the time the transaction is processed, and periodic service charges are recognized over the service period. The adoption of Topic 606 had no impact on Pinnacle Financial's revenue recognition practice for these services.

Insurance sales commissions — Insurance commissions are received from insurance companies in return for the placement of policies with customers. While additional services, such as claims assistance, may be provided over the term of the policy, the revenues are substantially earned at the time of policy placement. The only contingency in earning the revenue relates to the potential for subsequent cancellation of policies. Accordingly, revenue is recognized at the time of policy placement, net of an allowance for estimated policy cancellations. The adoption of Topic 606 had no impact on Pinnacle Financial's revenue recognition related to insurance sales commissions.

Gains on sales of other real estate — ASU 2014-09 creates Topic 610-20, under which a gain on sale should be recognized when a contract for sale exists and control of the asset has been transferred to the buyer. Topic 606 list several criteria which must exist to conclude that a contract for sale exists, including a determination that the institution will collect substantially all of the consideration to which it is entitled. This presents a key difference between the current and new guidance related to the recognition of the gain when the institution finances the sale of the property. Rather than basing recognition on the amount of the buyer's initial investment, which was the primary consideration under prior guidance, the analysis is now based on various factors including not only the loan to value, but also the credit quality of the borrower, the structure of the loan, and any other factors that may affect collectability. While these differences may affect the decision to recognize or defer gains on sales of other real estate in circumstances where Pinnacle Financial has financed the sale, the effects would not be material to its financial statements.

Recently Issued Accounting Pronouncements

In February 2018, the FASB issued Accounting Standards Update 2018-02,Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendments in this ASU addressed the income tax accounting treatment of the stranded tax effects within other comprehensive income due to the newly enacted federal corporate tax rate included in the Tax Cuts and Jobs Act issued December 22, 2017. 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 ofis permitted with retrospective application. Pinnacle Financial does not expect this accounting guidance is not expectedstandard to have a material impact onand will implement the Company's consolidated financial statements asstandard when the majority of its revenue streamfinal BNC tax return is generated from financial instruments which are not within thefinalized.

scopeIn January 2017, the FASB issued Accounting Standards Update No. 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment 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 ASU. However,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.

In January 2017, the FASB issued Accounting Standards Update 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The amendment in this ASU clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments are effective for fiscal years beginning after December 15, 2017, 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.


In February 2016, the FASB issued  Accounting Standards Update 2016-02, Leases guidance requiring the 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 us on January 1, 2019.  If this standard was effective as of the date of the financial statements included in this report, Pinnacle Financial would have recorded a right of use asset and liability in an amount similar to its current future minimum lease obligations.
In June 2016, the FASB issued  Accounting Standards Update 2016-13Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments (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 still evaluatingcurrently assessing the impact of the new guidance on its consolidated financial statements.

Other than those pronouncements discussed above and those which have been recently adopted, we do not believe there were noany other recently issued accounting pronouncements that are expected to materially impact Pinnacle Financial.

The amendments to the Bylaws include, among other changes, the adoption of changes to special shareholder meeting provisions and advance notice provisions.

Section 2.2 of the Bylaws was amended to specify that in order to be eligible to call a special meeting of shareholders, holders of record of 25% of the outstanding shares of Pinnacle Financial’s common stock (the aggregate percentage required to call a special meeting under the existing Bylaws) seeking to call a special meeting must hold such shares in a “net long” position.
